What is the Risk for Infection and Infection Control?

Infection risk arises when an individual’s natural defenses are insufficient to ward off invading microorganisms. These microorganisms, including bacteria, viruses, fungi, and parasites, can breach the body’s defenses through injuries or exposures, leading to infection in susceptible hosts. The human body is equipped with a sophisticated immune system, a network of cells and tissues dedicated to protecting against these threats. Key components of the immune system include the thymus, bone marrow, lymph nodes, spleen, appendix, tonsils, and Peyer’s patches in the small intestine. When the immune system falters in its response, infection takes hold.

Breaches in the integrity of the skin (integument), mucous membranes, soft tissues, or organs such as the kidneys and lungs become potential entry points for infections. These breaches can occur due to trauma, invasive medical procedures, or the invasion of pathogens via the bloodstream or lymphatic system. The development of an infection is a sequential process, requiring six essential elements: a causative organism, a reservoir for the organism, a mode of transmission from the reservoir to the host, a portal of entry into a susceptible host, and a susceptible host.

It’s crucial to distinguish between infection and infectious disease. Infection refers to the invasion and multiplication of microorganisms in body tissues. Infectious disease, however, is defined as the state where the infected host exhibits a decline in health and well-being as a direct result of the infection. If the body’s immune system interacts with an organism without producing noticeable symptoms, it is considered an infection without meeting the criteria for infectious disease.

Infectious diseases commonly spread through direct person-to-person transfer of bacteria, viruses, or other germs. This transmission can occur via various routes, including physical contact, airborne particles, sexual contact, or the sharing of intravenous (IV) drug paraphernalia. Factors such as inadequate resources, lack of knowledge about hygiene and infection control, and malnutrition significantly increase an individual’s susceptibility to infection.

Untreated infections can prolong healing processes and, in severe cases, may lead to life-threatening complications. Antimicrobials are frequently employed to combat infections when the causative organisms are susceptible. However, some organisms, such as the human immunodeficiency virus (HIV), are resistant to many antimicrobials. Immunization is another vital medical intervention, widely used for individuals at high risk of infection to bolster their defenses. Crucially, handwashing remains the most effective and simple method to disrupt the chain of infection and prevent its spread.

Infection control encompasses the policies and procedures implemented to manage and minimize the spread of infections within hospitals and other healthcare environments. The primary goal of infection control is to reduce infection rates. Infection control programs focus on the surveillance of healthcare-associated infections (HAIs) and utilize epidemiological principles to identify and mitigate risk factors for HAIs (Habboush et al., 2023).

Nursing interventions are tailored to the specific nature and severity of the infection risk. Nurses play a vital role in educating clients about recognizing the signs and symptoms of infection and implementing strategies to reduce their risk.

Causes of Infection

Various health problems and conditions can compromise the body’s defenses, creating an environment conducive to infection development. Understanding these risk factors is crucial for effective prevention and management.

Cause/Risk Factor Description Examples
Inadequate primary defenses The body’s initial protective barriers against infection are compromised. These include the skin, mucous membranes, and normal flora. – Skin breaches (cuts, wounds)– Tissue damage from burns or frostbite– Dry skin, compromising barrier function– Dehydrated mucous membranes– Disruption of normal flora due to antibiotic use
Insufficient knowledge to avoid exposure to pathogens Lack of awareness or understanding of infection prevention practices. – Improper handwashing techniques– Lack of awareness regarding germ spread– Inadequate surface cleaning and disinfection– Improper food handling and preparation
Compromised host defenses Impairment of the body’s secondary defenses, including the immune system, white blood cells, and inflammatory response. – Cancer and cancer treatments– Immunosuppression (e.g., post-transplant)– AIDS (Acquired Immunodeficiency Syndrome)– Diabetes mellitus– Malnutrition and nutritional deficiencies– Chronic diseases (heart, lung, kidney diseases)– Medications like chemotherapy and steroids
Compromised circulation Reduced blood flow to tissues, hindering immune cell access and waste removal. – Obesity– Lymphedema– Peripheral vascular disease– Smoking– Diabetes mellitus
A site for organism invasion Any opening in the body that provides a portal of entry for pathogens. – Surgical wounds and incisions– Burns – Skin breaks and lesions– Urinary tract infections (UTIs)– Respiratory infections– Central venous lines (CVLs)– Enteral feeding tubes
Contact with contagious agents Exposure to pathogens capable of causing infection through various routes. – Close contact with sick individuals– Touching contaminated surfaces– Inadequate respiratory etiquette (not covering mouth when coughing or sneezing)
Increased vulnerability of the infant Conditions that make infants more susceptible to infections due to immature immune systems and unique vulnerabilities. – Premature birth– Low birth weight– Congenital heart defects– Cleft lip or palate– Weakened immune system
Chronic diseases Long-term health conditions that weaken the immune system over time, increasing susceptibility to infections. – Heart disease– Lung disease– Kidney disease– Diabetes mellitus– Cancer
Multiple sex partners Engaging in sexual activity with multiple partners without practicing safe sex significantly increases the risk of sexually transmitted infections (STIs). – Unprotected sexual intercourse with multiple partners
Lack of immunization Failure to receive recommended vaccines leaves individuals vulnerable to preventable infections. – Missing routine childhood vaccinations– Not receiving recommended booster shots throughout life

Signs and Symptoms of Infection

Recognizing the signs and symptoms of infection is crucial for early detection and prompt intervention. These indicators can vary depending on the infection site, causative agent, and individual patient factors.

Subjective Data (Patient-Reported Symptoms)

  • Reports of fatigue and malaise, a general feeling of discomfort or illness.
  • Complaints of pain or discomfort, which may be localized or generalized.
  • Reports of decreased appetite or anorexia.

Objective Data (Observable Signs and Laboratory Findings)

  • Elevated body temperature or fever (hyperthermia), a key indicator of systemic infection.
  • Localized redness (erythema), swelling (edema), warmth, and pain at the infection site, indicating inflammation.
  • Purulent or unusual discharge from wounds, surgical sites, or body orifices, suggesting bacterial or fungal infection.
  • Increased heart rate (tachycardia), a physiological response to fever and infection.
  • Increased respiratory rate (tachypnea), another compensatory mechanism in response to infection and fever.
  • Laboratory findings indicating elevated white blood cell (WBC) count (leukocytosis), a hallmark of the body’s immune response to infection.
  • Positive results from culture tests (blood, urine, wound), identifying the specific pathogen causing the infection.
  • Signs of inflammation, such as elevated C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR).
  • Delayed wound healing or presence of non-healing wounds or skin breakdown, indicating potential infection.
  • Skin lesions, rashes, or changes in skin integrity.

Nursing Care Plans and Management

Nursing care plans for infection risk are essential for guiding comprehensive care, focusing on early identification, prompt treatment, and client and healthcare provider education. These plans aim to minimize healthcare-associated infections and promote patient well-being across diverse healthcare settings.

Nursing Problem Priorities

Prioritizing nursing actions is critical in managing patients at risk for or with an active infection. The following are key nursing priorities:

  1. Infection control and prevention. Implementing rigorous infection prevention measures is paramount to minimize the spread of infection to both the patient and others.
  2. Assessment and early detection. Timely identification of infection is crucial for initiating prompt and effective treatment. Early detection improves patient outcomes and reduces complications.
  3. Isolation precautions. Implementing appropriate isolation precautions based on the suspected or confirmed mode of transmission is essential to prevent cross-contamination and outbreaks.
  4. Surgical asepsis. Strict adherence to surgical asepsis principles is fundamental in preventing surgical site infections (SSIs) and ensuring patient safety during invasive procedures.
  5. Client and caregiver education. Empowering patients and their caregivers with knowledge about infection prevention strategies enhances adherence to care plans and reduces the risk of infection transmission in the home and community.

Nursing Assessment

A thorough nursing assessment is the cornerstone of identifying infection risk and detecting early signs of infection. Assessing both subjective and objective data is essential.

Assess for the following subjective and objective data:

  • Fever. Monitor body temperature for elevation above normal range, which may be accompanied by chills and sweating.
  • Pain or tenderness. Assess for localized pain, tenderness, or discomfort at potential infection sites.
  • Redness and swelling. Observe for signs of inflammation, including redness (erythema), warmth, swelling (edema), and pain at potential infection sites.
  • Tachycardia and tachypnea. Monitor vital signs for increased heart rate (tachycardia) and respiratory rate (tachypnea), which can indicate a systemic response to infection.
  • Malaise. Inquire about general feelings of discomfort, uneasiness, or being unwell, which may indicate early infection or systemic illness.
  • Increased white blood cell count. Review laboratory results for elevated white blood cell (WBC) count, which is a common indicator of infection.

Nursing Diagnosis

Based on the comprehensive nursing assessment, appropriate nursing diagnoses are formulated to address the identified risks and actual problems related to infection. These diagnoses guide the development of individualized care plans. Examples of nursing diagnoses relevant to infection risk include:

  • Risk for Infection related to inadequate primary defenses (e.g., broken skin integrity, immunosuppression, chronic disease).
  • Deficient Knowledge related to infection prevention and control measures, as evidenced by lack of awareness of proper hand hygiene or transmission modes.
  • Impaired Skin Integrity related to surgical incision, trauma, or pressure ulcer, increasing the risk of infection.
  • Hyperthermia related to infectious process, as evidenced by elevated body temperature and chills.

Nursing Goals

Establishing clear and measurable goals is essential for guiding nursing interventions and evaluating patient outcomes. Sample patient goals for individuals at risk for infection include:

  • The patient will remain free of infection throughout their hospital stay, as evidenced by normal vital signs, absence of fever, and no signs or symptoms of localized or systemic infection.
  • The patient will demonstrate effective infection control practices, including meticulous hand-washing technique, proper wound care, and adherence to isolation precautions (if applicable).
  • The patient will verbalize understanding of infection prevention strategies and risk factors, demonstrating knowledge for self-management at home.
  • The patient will maintain or restore optimal immune defenses through adequate nutrition, rest, and stress management.
  • The patient will experience early recognition of infection signs and symptoms, enabling prompt treatment initiation.
  • The patient will actively participate in care and treatment plan to alleviate or reduce problems related to infection.

Nursing Interventions and Actions

Nursing interventions are designed to address the identified nursing diagnoses and achieve the established patient goals. These interventions encompass assessment, infection control and prevention measures, isolation precautions, surgical asepsis, and patient education.

1. Performing Assessment and Early Detection

Early detection of infection is critical for initiating timely treatment and preventing complications. Comprehensive assessment is the first step in this process.

1.1. Assess for predisposing factors to infection.

  • Rationale: Identifying risk factors, such as breaks in skin integrity, chronic diseases, immunosuppression, and inadequate knowledge of infection control, helps determine the patient’s susceptibility to infection. Understanding these factors allows for targeted preventive measures. The common types of microorganisms causing infections are bacteria, rickettsiae, viruses, protozoa, fungi, and helminths.

1.2. Assess for local signs of infection in skin and mucous membranes.

  • Rationale: Localized infections often manifest with distinct signs and symptoms. These include swelling (edema), redness (erythema), pain or tenderness to touch, localized loss of function, and increased warmth at the affected site. For example, a patient colonized with Staphylococcus aureus may carry the bacteria on their skin without active infection. However, if a skin incision occurs, S. aureus can enter the wound, triggering a local inflammatory response and white blood cell migration to the site.

1.3. Monitor for systemic signs and symptoms of infection.

  • Rationale: Systemic infections affect the entire body and can present with varied symptoms depending on the organs involved. Regularly assess for:
    • Fever: Elevated body temperature is a primary indicator of systemic infection.
    • Chills and sweats: These often accompany fever and are indicative of the body’s thermoregulatory response to infection.
    • Tachycardia and tachypnea: Increased heart rate and respiratory rate are physiological responses to fever and the body’s attempt to compensate for infection.
    • Fatigue and malaise: Generalized weakness, fatigue, and feeling unwell are common systemic symptoms.
    • Anorexia: Loss of appetite can occur due to systemic illness and inflammatory responses.
    • Changes in mental status (confusion, lethargy): These can indicate severe infection, particularly in older adults or those with underlying conditions.

1.4. Monitor white blood cell (WBC) count and differential.

  • Rationale: WBC count is a key laboratory indicator of infection. An elevated WBC count (leukocytosis) signifies the body’s immune response to fight pathogens. Leukocytosis primarily involves an increase in neutrophils. Normal WBC range is 4,500 – 11,000 cells/µL.
    • Leukopenia (low WBC count, below 4,500 cells/µL): May indicate bone marrow suppression or overwhelming infection, increasing infection risk.
    • Leukocytosis (high WBC count, above 11,000 cells/µL): Typically indicates an inflammatory response, such as infection.
    • In older adults, infection may be present without a significant increase in WBC count.
    • WBC differential: Provides information about specific types of WBCs, which can further indicate the nature of infection (e.g., increased neutrophils in bacterial infections, increased lymphocytes in viral infections).

1.5. Assess and monitor nutritional status, weight, weight loss history, and serum albumin levels.

  • Rationale: Nutritional status significantly impacts immune function. Malnutrition or deficiencies in micronutrients can impair cellular immune response, increasing susceptibility to infection.
    • Micronutrient deficiencies: Particularly vitamin D, zinc, vitamin E, and selenium, can weaken immune function and reduce infection resistance.
    • Serum albumin: Low albumin levels can indicate poor nutritional status and compromised immune function.
    • Vitamin D deficiency is linked to increased risk of respiratory infections (Calder et al., 2020).

1.6. Investigate medication and treatment history for immunosuppressive agents.

  • Rationale: Certain medications and treatments can suppress the immune system, increasing infection risk.
    • Immunosuppressant medications: Antineoplastic agents (chemotherapy), corticosteroids, anti-rejection drugs, and tumor necrosis factor inhibitors can impair immune function.
    • Corticosteroids and TNF inhibitors increase the risk of fungal infections (Centers for Disease Control and Prevention, 2020).
    • Immunosuppressants reduce the intensity of the immune response (Hussain & Khan, 2022).

1.7. Assess immunization status and history.

  • Rationale: Immunizations provide acquired active immunity against specific pathogens. Incomplete immunization history increases susceptibility to vaccine-preventable infections.
    • Vaccination history: Inquire about childhood and adult vaccinations, including routine and booster shots.
    • Risk-benefit assessment: Evaluate individual and community risks and benefits of vaccination programs in terms of morbidity, mortality, and costs.
    • Vaccine success: Vaccination programs have significantly reduced the incidence of many infectious diseases.

1.8. Observe for subtle signs of infection in older adults.

  • Rationale: Older adults may present with atypical infection symptoms.
    • Low-grade fever or new onset of confusion: These can be early indicators of infection in older adults and should be promptly reported.
    • Non-specific decline in functional status: Infection in older adults may manifest as a general decline from their baseline, rather than classic infection symptoms.
    • Cognitive impairment: Can mask or complicate the presentation of infection in older adults, reducing their ability to communicate symptoms.
    • Fever may be absent in 30-50% of frail older adults with serious infections (Debonera & Simmons, 2021).

1.9. Obtain travel history from patients.

  • Rationale: Travel history is important for identifying potential exposure to geographically specific infections, especially for patients presenting with infectious symptoms.
    • Travel-associated illnesses: A significant percentage of travelers to low- and middle-income countries develop travel-related health problems.
    • Incubation periods: Post-travel infections may manifest shortly after return or months to years later.
    • Travel history helps contextualize infectious symptoms for accurate diagnosis and treatment (Fairley, 2023).

1.10. Determine travel exposures.

  • Rationale: Specific exposures during travel, such as food and water consumption, insect bites, and activities, can further narrow down potential infectious agents.
    • Exposure risks: Contaminated food or water, insect bites, freshwater swimming, and other activities vary in risk for different diseases.
    • Accommodation and activities: Type of accommodation and travel activities influence disease acquisition risk.
    • Travelers visiting friends and relatives are at higher risk for malaria, typhoid fever, and other diseases due to longer stays, remote destinations, and less pre-travel advice seeking (Fairley, 2023).

1.11. For pregnant patients, assess amniotic membrane intactness.

  • Rationale: Prolonged rupture of amniotic membranes increases infection risk for both mother and neonate.
    • Prolonged rupture of membranes (PROM): Provides a pathway for pathogens to ascend into the uterus, increasing risk of chorioamnionitis and neonatal sepsis.
    • Many pregnant patients with infections are asymptomatic, requiring high clinical awareness and screening (Smith & Basistha, 2023).

1.12. Screen pregnant women for Group B Streptococcus (GBS) at 35-37 weeks gestation.

  • Rationale: GBS is a common cause of severe neonatal infections. Screening allows for intrapartum antibiotic prophylaxis to prevent neonatal GBS disease.
    • Vaginal and rectal swab: Screening is performed via vaginal or rectal swab culture at 35-37 weeks.
    • Introitus and rectum: Culture sites should include the introitus (just inside hymenal ring) and rectum (beyond sphincter) for optimal detection.
    • GBS is the most common cause of life-threatening infections in newborns (Smith & Basistha, 2023).

1.13. Identify factors reducing hand hygiene effectiveness.

  • Rationale: Hand hygiene effectiveness can be compromised by skin conditions and jewelry.
    • Skin condition: Cracks, dermatitis, or cuts on hands can harbor bacteria, even after hand hygiene.
    • Jewelry: Rings and bracelets increase microbial count on hands and hinder effective hand hygiene.
    • For religious bracelets that cannot be removed, push them as high as possible above the wrist before hand hygiene (McCutcheon & Doyle, 2015).

1.14. Assess for latex allergy history.

  • Rationale: Latex allergy is a potential risk for healthcare workers and patients exposed to latex-containing medical supplies.
    • Latex allergy: Reaction to proteins in natural rubber latex.
    • Risk groups: Healthcare workers, patients with multiple surgeries, frequent latex exposure, and those with other allergies (rhinitis, food allergies).
    • Powdered latex gloves are associated with increased latex allergy risk (McCutcheon & Doyle, 2015).

1.15. Perform urgent risk assessment for blood and body fluid exposure after incidents.

  • Rationale: Prompt risk assessment after exposure to blood or body fluids is crucial for determining post-exposure prophylaxis needs to prevent bloodborne infections.
    • Timeframe: Risk assessment should be completed within two hours of exposure incident.
    • Assessment location: Emergency department or urgent care center.
    • Risk factors: Assess exposure type, source infectivity risk, and exposed person’s susceptibility (HIV, hepatitis B, hepatitis C).
    • (McCutcheon & Doyle, 2015).

1.16. Monitor C-reactive protein (CRP) levels.

  • Rationale: CRP is an acute-phase reactant and a sensitive marker of inflammation, including infection.
    • CRP kinetics: Rises within 6 hours of infection, peaks at 48 hours, half-life of 19 hours.
    • Therapeutic monitoring: CRP levels can be used to monitor infection severity and treatment response.
    • CRP is less affected by age-related immune changes (immunosenescence) and comorbidities in older adults (Debonera & Simmons, 2021).

1.17. Utilize validated biomarkers for infection prediction in older adults.

  • Rationale: Validated biomarkers and scoring systems can aid in early infection diagnosis and risk stratification in older adults, who often present atypically.
    • CURB-65 score: Validated in older adults, assesses confusion, uremia, respiratory rate, blood pressure, and age ≥65 to predict mortality and guide care setting.
    • Pneumonia Severity Index (PSI): Widely used to risk-stratify patients with community-acquired pneumonia (CAP) to determine inpatient vs. outpatient management.
    • Prognostic modeling is increasingly important for managing infections in the aging population (Debonera & Simmons, 2021).

2. Infection Control and Prevention

Implementing comprehensive infection control measures is essential to break the chain of infection and prevent healthcare-associated infections (HAIs).

2.1. Maintain strict asepsis during invasive procedures and wound care.

  • Rationale: Aseptic technique minimizes pathogen transmission during procedures that breach the body’s natural barriers.
    • Procedures requiring asepsis: Dressing changes, wound care, intravenous therapy, catheter insertion and handling, surgical procedures.
    • Chain of infection interruption: Asepsis interrupts the chain of infection, preventing pathogen spread.
    • Urinary catheter insertion: Use sterile, pre-assembled, closed urinary drainage systems with the smallest possible catheter size.
    • Wound care: Open wounds are high infection risk; aseptic technique is crucial during dressing changes and wound management.

2.2. Practice diligent hand hygiene.

  • Rationale: Hand hygiene is the single most effective measure to prevent infection transmission.
    • “5 Moments for Hand Hygiene”:
      • Before touching a patient.
      • Before clean/aseptic procedures (wound dressing, IV insertion).
      • After body fluid exposure risk.
      • After touching a patient.
      • After touching patient surroundings.
    • Handwashing technique: Use friction and running water to physically remove microorganisms. Wash with antiseptic soap and water for at least 15 seconds, followed by alcohol-based hand rub if available.
    • Alcohol-based hand rubs (ABHRs): For non-visibly soiled hands, ABHRs are faster and more effective than plain soap.
    • Plain soap reduces bacteria; antimicrobial soap is better; ABHRs are most effective (Gilmartin, 2019).

2.3. Promote optimal nutrition.

  • Rationale: Adequate nutrition supports immune system function and tissue health, enhancing the body’s ability to fight infection.
    • Protein and calorie-rich diet: Provides building blocks for tissue repair and immune cell production.
    • Balanced diet: Ensures intake of essential vitamins and minerals for immune function.
    • Micronutrients: Zinc, vitamin E, and vitamin D are crucial for immune function, especially in older adults.
    • Nutrition intervention can mitigate age-related immune decline and improve infection resistance (Pae & Wu, 2017).

2.4. Change soiled or wet dressings and bandages promptly.

  • Rationale: Soiled dressings provide a moist, warm environment conducive to bacterial growth and can become a source of infection.
    • Aseptic technique: Use aseptic technique during dressing changes and wound cleansing.
    • Frequency: Change dressings as prescribed (typically on postoperative days 2-5 for surgical wounds), and more frequently if visibly soiled.
    • Healthcare provider notification: Inform the healthcare provider if dressings require frequent changes due to excessive drainage or soiling.

2.5. Assist patients with appropriate skin hygiene.

  • Rationale: Regular skin cleansing, especially handwashing, reduces viral transfer to mucous membranes and prevents self-inoculation.
    • Frequent cleansing: Simple, inexpensive, and effective strategy for infection prevention.
    • Handwashing: Reduces viral transfer to nose, mouth, and eyes.
    • (Rivers et al., 2021).

2.6. Dispose of soiled linens properly.

  • Rationale: Soiled linens, especially those contaminated with body fluids, can harbor pathogens and contribute to cross-contamination.
    • Pathogen reservoir: Soiled linens can harbor bacteria, viruses, and fungi.
    • Proper disposal: Prevents pathogen spread to healthcare workers and other patients.

2.7. Avoid talking, coughing, or sneezing over open wounds or sterile fields.

  • Rationale: Respiratory droplets can contaminate sterile fields and open wounds, introducing pathogens.
    • Respiratory pathogens: Easily aerosolized and highly contagious.
    • Respiratory hygiene: Critical for maintaining a healthy environment.
    • Symptom awareness: Individuals with respiratory symptoms should be aware and practice respiratory etiquette.
    • (DePaola & Grant, 2019).

2.8. Wear gloves when handling patient body fluids.

  • Rationale: Gloves provide a barrier against microorganisms present in patient body fluids, protecting healthcare workers from exposure.
    • Barrier protection: Gloves prevent direct hand contact with patient microflora.
    • Glove disposal: Discard gloves after each patient contact and perform hand hygiene.
    • Handwashing after glove removal: Hands can become colonized with microorganisms in the warm, moist glove environment; handwashing is essential after glove removal.

2.9. Instruct patients on hand hygiene before handling food or eating.

  • Rationale: Hand hygiene before eating prevents ingestion of pathogens and reduces risk of foodborne infections.
    • Bacterial transmission: Hands of healthcare workers are a major route of bacterial transmission in healthcare settings.
    • Effective handwashing: Vigorous scrubbing for at least 15 seconds, paying attention to nail beds and between fingers.

2.10. Encourage increased fluid intake (unless contraindicated).

  • Rationale: Adequate fluid intake promotes urinary tract health, hydration, and secretion thinning.
    • Urinary tract health: Increased fluids dilute urine, promote frequent bladder emptying, and reduce urinary stasis, lowering UTI risk.
    • Hydration: Replaces fluids lost due to fever and helps maintain skin and tissue moisture.
    • Secretion thinning: Helps thin respiratory secretions, facilitating expectoration.
    • Contraindications: Heart failure, kidney failure, or other conditions requiring fluid restriction.

2.11. Encourage coughing and deep breathing exercises and frequent position changes.

  • Rationale: These measures prevent respiratory secretion stasis, reducing the risk of pneumonia and other respiratory infections.
    • Secretion stasis: Stasis in lungs and bronchial tree increases risk of microbial infection and pneumonia.
    • Chest physiotherapy: Includes postural drainage, chest percussion and vibration, and breathing retraining to remove secretions and improve ventilation.

2.12. Recommend soft-bristled toothbrushes and stool softeners.

  • Rationale: Protect mucous membranes from trauma, reducing pathogen entry points.
    • Oral mucous membranes: Hard-bristled toothbrushes can damage mucous membranes, creating entry points for pathogens. Soft toothbrushes are gentler.
    • Anal mucous membranes: Straining during bowel movements can damage anal mucosa, increasing infection risk, especially in immunocompromised patients. Stool softeners prevent constipation and straining.

2.13. Promote nail care: keep nails short and clean.

  • Rationale: Short, clean nails reduce microbial load and prevent pathogen harboring.
    • Microorganism reservoir: Rough nail edges and hangnails can harbor microorganisms.
    • Hand hygiene effectiveness: Short, clean nails improve hand hygiene effectiveness.
    • Nail length: Keep nails short (max ¼ inch), clean undersides with soap and water frequently.
    • (Centers for Disease Control and Prevention, 2022).

2.14. Encourage sleep and rest.

  • Rationale: Adequate sleep strengthens immune function and reduces infection susceptibility.
    • Immune modulation: Sleep is essential for immune response regulation.
    • Sleep deprivation: Weakens immunity, increasing infection risk.
    • Common cold: Shorter sleep duration is associated with increased cold susceptibility.
    • Regular sleep routine: Boosts immune system effectiveness.
    • (Ragnoli et al., 2022).

2.15. Assist patients to learn stress-reducing techniques.

  • Rationale: Excessive stress can suppress immune function, increasing infection risk.
    • Stress hormones: Chronic stress elevates stress hormones, which can impair immune responses.
    • Stress reduction techniques: Meditation, deep breathing exercises, mindfulness can lower stress hormones and improve immune balance.

2.16. Follow proper cleaning and disinfecting procedures for patient environment and equipment.

  • Rationale: Environmental cleaning and disinfection reduce pathogen load in the patient environment.
    • Environmental controls: Prevent microorganism growth and spread from surfaces and equipment.
    • Cleaning procedures: Use damp cloth dusting (avoid shaking linens), clean contaminated objects, sterilize or disinfect equipment and patient-care items according to agency policy.
    • (McCutcheon & Doyle, 2015).

2.17. Avoid eating or drinking in patient care areas.

  • Rationale: Eating and drinking in patient areas increases infection transmission risk for healthcare workers.
    • Portal of exit: Mouth is a common portal of exit for pathogens.
    • Designated areas: Eat and drink in designated areas away from patient care environments.
    • (Ernstmeyer & Christman, 2019).

2.18. Avoid artificial nails and nail extenders; keep nails short.

  • Rationale: Artificial nails and extenders harbor higher bacterial loads and are difficult to clean, increasing infection risk.
    • Bacterial load: Artificial nails increase bacterial load up to nine times.
    • Cleaning difficulty: Long nails and artificial nails are harder to clean effectively.
    • Glove punctures: Long nails increase glove puncture risk.
    • Nail length recommendation: Max ¼ inch, no extenders for healthcare workers.
    • (McCutcheon & Doyle, 2015).

2.19. Use warm water and appropriate products for hand hygiene.

  • Rationale: Warm water and proper soaps optimize hand hygiene effectiveness and skin integrity.
    • Water temperature: Warm water removes oils less aggressively than hot water, reducing skin damage.
    • Soap quantity: Use adequate soap to dissolve fatty materials and oils; water alone is insufficient for soiled hands.
    • Product dispensing: Use disposable pump containers for soaps and hand rubs; avoid topping off containers to prevent contamination.

2.20. Carry alcohol-based hand rub (ABHR) for frequent use.

  • Rationale: ABHRs are convenient and effective for routine hand hygiene in healthcare settings.
    • ABHR effectiveness: More effective than soap and water against many germs and viruses.
    • ABHR convenience: Faster to use, readily available at point of care.
    • Alcohol concentration: Use ABHRs with 60-90% alcohol concentration.
    • (McCutcheon & Doyle, 2015).

2.21. Manage blood and body fluid exposures immediately.

  • Rationale: Prompt management of exposures minimizes risk of bloodborne pathogen transmission.
    • Post-exposure protocol: Wash exposed area thoroughly with soap and water (or normal saline for mucous membranes).
    • Avoid manipulation: Do not promote bleeding of percutaneous injuries by cutting or squeezing.
    • Agency policy: Refer to agency policy for blood/body fluid exposure management.
    • Exposure risk assessment: Assess exposure type, source risk, and recipient susceptibility to HIV, hepatitis B, and hepatitis C.
    • (McCutcheon & Doyle, 2015).

2.22. Provide micronutrient supplementation as appropriate.

  • Rationale: Micronutrient and omega-3 fatty acid supplementation can support optimal immune function, especially in individuals with nutritional gaps.
    • Micronutrient benefits: Vitamins and trace elements (A, B6, B12, folate, C, D, E, zinc, iron, selenium, magnesium, copper) support immune cell function. Consider multivitamin/trace mineral supplements.
    • Vitamin C: Doses >200 mg/day support respiratory infection risk reduction. Higher doses (1-2 g/day) may be beneficial during infection.
    • Vitamin D: 2000 IU/day supplementation reduces acute respiratory infection risk.
    • Zinc: 8-11 mg/day recommended intake; deficiency impairs immunity and increases diarrheal and respiratory morbidity.
    • Omega-3 fatty acids (EPA+DHA): 250 mg/day recommended intake; support effective immune response and inflammation resolution.
    • (Calder et al., 2020).

2.23. Ensure staff vaccinations and health assessments are up-to-date.

  • Rationale: Healthcare worker vaccinations protect both staff and patients from vaccine-preventable infections.
    • Influenza vaccination: Annual influenza vaccine recommended for all healthcare personnel.
    • Tuberculosis screening: Periodic testing for latent TB is recommended.
    • Employee health programs: Proactive programs and policies promote employee well-being and infection prevention.
    • (Habboush et al., 2023).

2.24. Implement antimicrobial stewardship programs.

  • Rationale: Antimicrobial stewardship programs control antimicrobial resistance, improve patient outcomes, and reduce healthcare costs.
    • Antimicrobial resistance: Monitor antimicrobial susceptibility profiles to detect and manage resistance patterns.
    • Antimicrobial use monitoring: Correlate resistance trends with antimicrobial usage to optimize prescribing practices.
    • (Habboush et al., 2023).

2.25. Collaborate on infection control policies and interventions.

  • Rationale: Collaborative development and implementation of infection control policies ensure comprehensive and effective strategies.
    • Infection control program goals: Develop, implement, and evaluate policies to minimize HAIs.
    • Intervention types: Vertical interventions (pathogen-specific, e.g., MRSA surveillance and isolation) and horizontal interventions (targeting transmission mechanisms, e.g., hand hygiene).
    • (Habboush et al., 2023).

2.26. Promote appropriate oral hygiene.

  • Rationale: Oral hygiene is often overlooked but is linked to infection spread, poor health outcomes, and malnutrition.
    • Oral care frequency: Perform oral care in the morning, after meals, and before bedtime.
    • Poor oral care consequences: Associated with infection spread, poor health outcomes, and malnutrition.
    • (Ernstmeyer & Christman, 2019).

2.27. Encourage daily bathing.

  • Rationale: Daily bathing, especially with chlorhexidine products, can significantly reduce HAIs.
    • Bathing frequency: Daily bathing can have a powerful impact on infection spread reduction.
    • Chlorhexidine bathing: Daily bathing with chlorhexidine gluconate wipes or solutions is more effective than soap and water in reducing HAIs.
    • Wash basins: Wash basins can be reservoirs for pathogens.
    • (Ernstmeyer & Christman, 2019).

2.28. Disinfect mobile phones and gadgets frequently.

  • Rationale: Mobile devices are frequently contaminated with pathogens and can contribute to infection spread in healthcare settings.
    • Mobile device contamination: Cell phones and mobile devices carry many pathogens, often more contaminated than toilet seats.
    • Disinfection frequency: Healthcare workers, patients, and visitors should frequently disinfect mobile devices with disinfectant wipes.
    • (Ernstmeyer & Christman, 2019).

3. Implementing Isolation Precautions

Isolation precautions are implemented to prevent and control the transmission of infections based on the mode of transmission of specific microorganisms.

3.1. Instruct patients not to share personal care items.

  • Rationale: Sharing personal care items can facilitate pathogen transmission.
    • Personal item examples: Toothbrushes, towels, razors, combs, makeup.
    • Pathogen transmission: Personal items can harbor bacteria, viruses, fungi, and bloodborne pathogens (razors).
    • Prevention strategy: Avoid sharing personal care items to reduce infection spread.

3.2. Limit visitors and reinforce infection symptom reporting.

  • Rationale: Limiting visitors reduces pathogen introduction and transmission.
    • Visitor restriction: Reduces exposure to potential pathogens.
    • Symptom reporting: Instruct visitors and staff with respiratory infection symptoms to avoid contact and report symptoms.
    • Respiratory etiquette: Visitors and staff with symptoms should practice respiratory hygiene (covering coughs, mask use).
    • (DePaola & Grant, 2019).

3.3. Provide surgical masks to coughing visitors and enforce respiratory etiquette.

  • Rationale: Masks and respiratory etiquette prevent droplet transmission of respiratory pathogens.
    • Droplet transmission prevention: Masks prevent droplet spread from coughing or sneezing visitors.
    • Respiratory etiquette: Instruct visitors to cover mouth and nose when coughing or sneezing (using elbow), use tissues for secretions and dispose immediately, perform hand hygiene.
    • Protective barriers: Provide masks, tissues, no-touch receptacles in patient rooms and common areas.
    • (DePaola & Grant, 2019).

3.4. Place high-risk patients in protective isolation.

  • Rationale: Protective isolation (reverse isolation) protects severely immunocompromised patients from environmental pathogens.
    • Indications: Neutropenia (low WBC count) and other severe immunocompromising conditions.
    • Room requirements: Single-patient room, adequate ventilation (if possible).
    • (Mohty et al., 2018).

Initiate specific precautions for suspected agents as determined by CDC protocol.

Standard Precautions

Standard precautions. These are the foundational infection control practices used for all patients, regardless of suspected or confirmed infection status. They are based on the principle that all patients may be colonized or infected with microorganisms.

  • Hand hygiene. Perform hand hygiene frequently during patient care, especially when hands are visibly soiled or contaminated with biological material. Use soap and water for visibly soiled hands; alcohol-based hand rubs are acceptable for routine decontamination when hands are not visibly soiled.
  • Glove use. Wear gloves when there is potential contact with patient secretions or excretions. Discard gloves after each patient contact and perform hand hygiene.
  • Needlestick prevention. Handle needles, scalpels, and sharps with extreme care. Do not recap used needles; dispose of them directly into puncture-resistant sharps containers. Use a one-handed scoop technique if recapping is unavoidable.
  • Avoidance of splash and spray. Use appropriate barriers (goggles, facemask, gown) when procedures may generate splashes or sprays of body fluids.

Airborne Precautions

Airborne precautions. These are required for patients with confirmed or suspected airborne infections, such as pulmonary tuberculosis (TB), varicella (chickenpox), measles, and other airborne pathogens.

  • Airborne infection isolation room (AIIR): Place patients in AIIRs, which are single-patient rooms with negative air pressure, rapid air turnover, and direct exhaust of air outdoors or HEPA filtration.
  • N95 respirators: Healthcare personnel entering the AIIR must wear fit-tested N95 respirators.
  • Room signage: Post a sign outside the room alerting personnel to airborne precautions.
  • Limit susceptible personnel entry: Restrict room entry to non-susceptible individuals.
  • Keep door closed: Keep the AIIR door closed at all times.

Droplet Precautions

Droplet precautions. These are used for infections transmitted by large respiratory droplets generated during coughing, sneezing, or talking, such as influenza and meningococcus.

  • Facemask: Wear a facemask when within 3-6 feet of the patient.
  • PPE: Masks and goggles or face shields are recommended PPE for droplet precautions.

Contact Precautions

Contact precautions. These are used for infections spread by direct or indirect contact, such as antibiotic-resistant organisms (e.g., MRSA, VRE) and Clostridium difficile (C. difficile).

  • Gloves and gowns: Wear gloves and gowns upon room entry. Remove gloves and gowns before leaving the patient environment and perform hand hygiene.
  • Dedicated equipment: Use dedicated patient-care equipment (e.g., stethoscope, blood pressure cuff). If shared equipment is unavoidable, clean and disinfect it thoroughly between patients.
  • Hand hygiene: For C. difficile infection, hand hygiene with soap and water is more effective than alcohol-based hand rubs. C. difficile spores are resistant to alcohol.
  • Bleach-based disinfectants: Use bleach-containing cleaning products for environmental disinfection in C. difficile rooms, as bleach kills spores. Clean frequently touched surfaces daily or when visibly soiled.

Proper Wearing of PPE

Wear personal protective equipment (PPE) properly. Proper donning and doffing of PPE is crucial to prevent self-contamination and infection spread.

  • Gloves. Wear gloves for direct patient care. Perform hand hygiene after glove removal. Double gloving may be considered for surgical procedures for enhanced infection prevention (Kening, 2023).
  • Masks. Use masks, goggles, and face shields to protect mucous membranes during procedures with potential splashes or sprays of body fluids. N95 respirators offer the highest respiratory protection; cloth masks offer the least (Kening, 2023).
  • Gowns. Wear gowns for direct contact with uncontained secretions or excretions. Remove gowns before leaving the patient room and perform hand hygiene. Do not reuse gowns, even for the same patient. USP 800 guidelines specify gown standards for handling hazardous drugs (Kening, 2023).

Limit patient transport. Minimize patient transport outside of the isolation room to essential purposes only (e.g., diagnostic procedures). Use appropriate barriers on the patient during transport, consistent with the transmission mode. Notify receiving departments of necessary precautions.

Institute enteric precautions as indicated. Enteric precautions are used for suspected or confirmed gastrointestinal pathogens, such as C. difficile or norovirus. Wear gowns in the patient room to prevent fecal contamination of clothing. Use soap and water for hand hygiene (hand sanitizers are ineffective against C. difficile spores). Implement special disinfection procedures after patient discharge, including mattress disinfection (Ernstmeyer & Christman, 2019).

Place signages on doors of isolation precaution rooms. Clearly display signs on isolation room doors indicating the type of precautions required. Single-patient rooms are preferred; cohorting patients with the same infection may be acceptable. Private bathrooms are ideal (McCutcheon & Doyle, 2015).

Perform appropriate and systematic donning of PPE. Don PPE immediately before patient interaction and remove it immediately after, followed by hand hygiene.

Donning of PPE (Putting On)

  1. Remove rings, bracelets, and watches. Perform hand hygiene.
  2. Apply waterproof long-sleeved gown, tie neck and waist strings.
  3. Apply surgical or N95 mask, ensuring a secure fit.
  4. Apply goggles or face shield over eyes.
  5. Apply non-sterile gloves over gown cuffs.

Doffing of PPE (Taking Off)

  1. Remove gloves first. Grasp outer glove edge at wrist and peel off, turning inside out. With ungloved hand, peel off second glove. Perform hand hygiene.
  2. Remove gown. Untie neck ties, pull gown forward, roll inward into a ball, and discard. Perform hand hygiene.
  3. Remove eye protection (goggles or face shield) by handling clean parts (arms or headband).
  4. Remove mask or N95 respirator by touching ties, ear loops, or straps. Remove bottom tie first, then top tie (if tied). Lean forward to remove mask. Perform hand hygiene.
    (Ernstmeyer & Christman, 2019).

4. Promoting Surgical Asepsis

Surgical asepsis, or sterile technique, is critical in preventing surgical site infections (SSIs) and ensuring patient safety during invasive procedures.

4.1. Perform thorough surgical scrubbing.

  • Rationale: Surgical scrubbing removes transient and reduces resident microorganisms on hands and arms, minimizing surgical field contamination.
    • Traditional scrub: Antiseptic soap and water scrub of hands and arms.
    • Alternative scrubs: Alcohol-based or scrubless soaps may be used when gross contamination is absent.

4.2. Wear appropriate sterile PPE for surgical procedures.

  • Rationale: Sterile PPE creates a barrier between surgical team members and the sterile surgical field.
    • Sterile attire: Sterile gowns, gloves, caps (covering hair), and masks (covering nose and mouth) are required for surgical team members.
    • Sterile field contact: Only scrubbed, gloved, and gowned personnel can touch sterile objects in the surgical field.

4.3. Meticulously prepare the surgical site.

  • Rationale: Surgical site preparation reduces microorganisms at the incision site, lowering SSI risk.
    • Skin cleansing: Cleanse a wide area of skin around the surgical site with antiseptic solution.
    • Hair removal: If needed, remove hair immediately before surgery with electric clippers to minimize infection risk.

4.4. Ensure all surgical articles are sterile.

4.8. Avoid contamination when opening sterile equipment.

  • Rationale: Proper opening techniques preserve sterility during transfer of sterile supplies to the sterile field.
    • Package edges: Edges of opened sterile packages are considered unsterile.
    • Sterile supply delivery: Dispense sterile supplies and solutions to the sterile field or scrubbed personnel in a manner that maintains sterility.

4.9. Do not use compromised sterile equipment.

  • Rationale: Compromised sterile barriers (punctures, moisture, tears) indicate contamination.
    • Barrier breach: Any breach in a sterile barrier renders the item or field contaminated.
    • Replacement: Replace any sterile equipment with compromised barriers.

4.10. Avoid touching the border of a sterile field.

  • Rationale: The one-inch border around a sterile field is considered contaminated.
    • Sterile field border: A one-inch border around the sterile drape edge is non-sterile.
    • Object placement: Place all sterile objects within the sterile field, away from the one-inch border.

4.11. Constantly monitor every sterile field.

  • Rationale: Continuous monitoring and maintenance are necessary to ensure sterile field integrity.
    • Sterile field vigilance: Constantly monitor sterile fields for any breaks in technique or potential contamination.
    • Doubtful sterility: Consider any item of questionable sterility as non-sterile.
    • Preparation timing: Prepare sterile fields as close as possible to the time of use to minimize contamination risk.

4.12. Ensure movements around the sterile field do not cause contamination.

  • Rationale: Proper movement and behavior in the sterile field prevent contamination.
    • Movement restrictions: Avoid sneezing, coughing, laughing, or talking directly over the sterile field.
    • Safe margin: Maintain a safe margin between sterile and non-sterile areas.
    • No reaching over: Never reach across a sterile field.
    • Pouring sterile solutions: When pouring sterile solutions, only the lip and inner cap of the pouring container are sterile. Avoid container contact with the sterile field and prevent splashes.
    • (McCutcheon & Doyle, 2015).

4.13. Select sterile or clean gloves based on procedure needs.

  • Rationale: Appropriate glove selection depends on the procedure and risk of contamination.
    • Clean gloves: Use for procedures with risk of body fluid contact or contact with contaminated surfaces.
    • Sterile gloves: Use for invasive procedures or when contact with sterile sites, tissues, or body cavities is anticipated (Ernstmeyer & Christman, 2021).
