Diverticular disease, encompassing both diverticulosis and diverticulitis, is a prevalent condition characterized by the formation of diverticula, or pouches, in the colon. While diverticulosis often remains asymptomatic, diverticulitis arises when these pouches become inflamed or infected, leading to a range of symptoms. Predominantly affecting the sigmoid colon, where the intestinal walls are weaker, understanding diverticulitis and its management is crucial for effective nursing care.
This article provides an in-depth guide to diverticulitis, focusing on nursing diagnoses, assessments, interventions, and care plans to optimize patient outcomes.
Understanding Diverticulitis: A Nursing Perspective
Diverticulitis occurs when diverticula, pouches that form in the wall of the colon, become inflamed or infected. This condition can range in severity from mild, manageable cases to severe instances requiring hospitalization and even surgical intervention. Nurses play a vital role in the care of patients with diverticulitis, from initial assessment and diagnosis to implementing treatment plans and providing crucial patient education.
Key Aspects of Diverticulitis for Nursing Professionals:
- Pathophysiology: Diverticulitis involves inflammation and potential infection of the diverticula, often due to micro-perforation.
- Clinical Manifestations: Symptoms can vary but commonly include abdominal pain (especially in the left lower quadrant), fever, changes in bowel habits, nausea, and vomiting.
- Diagnosis: Diagnosis typically involves clinical evaluation, imaging studies like CT scans, and ruling out other conditions.
- Treatment Goals: The primary goals of treatment are to reduce inflammation, manage infection, relieve symptoms, and prevent complications.
- Nursing Care Focus: Nursing care centers on pain management, bowel rest, infection control, nutritional support, patient education, and monitoring for complications.
Nursing Assessment for Diverticulitis
A thorough nursing assessment is the cornerstone of effective care for patients with diverticulitis. This assessment includes gathering both subjective and objective data to understand the patient’s condition comprehensively.
Subjective Data: Health History Review
Collecting subjective data involves understanding the patient’s symptoms and medical history. Key areas to explore include:
1. Symptom Evaluation:
- General Symptoms: Inquire about abdominal cramps, tenderness, bloating, and changes in bowel habits like constipation. These symptoms, while common in other GI disorders, can indicate diverticular issues.
- Diverticulitis-Specific Symptoms: Assess for acute abdominal pain (location, intensity, character), distention, changes in bowel sounds, nausea and vomiting, chills, constipation, and rectal bleeding. Understanding the specific characteristics of pain is critical for differential diagnosis.
2. Bowel Habit Changes:
- Investigate any alterations in bowel frequency, consistency, or ease of passage. Changes, especially when accompanied by abdominal pain, are significant.
- Explore associated symptoms like nausea and vomiting, which may suggest complications such as bowel obstruction.
3. Risk Factor Identification:
- Non-modifiable Risk Factors:
- Age: Diverticular disease prevalence increases significantly after age 40.
- Ethnicity: Higher prevalence is noted in Western populations.
- Modifiable Risk Factors:
- Diet: Low-fiber, high-fat diets are strongly linked to diverticular disease. Educate patients about the importance of dietary fiber.
- Physical Inactivity: Lack of exercise increases the risk. Promote regular physical activity as a preventative measure.
- Obesity: Associated with inflammation and altered gut microbiota, increasing risk. Counsel patients on weight management.
- Smoking: Reduces mucus production in the colon, elevating diverticulitis risk. Provide smoking cessation resources.
4. Medication History:
- NSAID Use: Regular use of aspirin or NSAIDs is linked to a higher risk of diverticulitis and diverticular bleeding. Document medication history thoroughly.
Objective Data: Physical Assessment
Objective data is gathered through physical examination and diagnostic procedures. Key components of the physical assessment include:
1. Vital Signs Monitoring:
- Temperature: Fever (≥100.4°F or 38.0°C) indicates infection associated with diverticulitis. Monitor temperature regularly.
2. Abdominal Examination:
- Palpation: Assess for tenderness, particularly in the left lower quadrant, which is characteristic of diverticulitis. Note any guarding, rigidity, or rebound tenderness, which may suggest bowel perforation. Palpate for masses, which could indicate abscess formation. Gentle and systematic palpation is essential.
- Auscultation: Bowel sounds may be normal or hypoactive. Document bowel sound characteristics.
3. Rectal Examination:
- Perform a rectal exam to assess for rectal mucosal abnormalities and check for rectal bleeding. This is important for identifying potential lower GI bleeding.
Diagnostic Procedures and Data Review
Diagnostic procedures confirm the diagnosis and assess the severity of diverticulitis. Nurses play a key role in preparing patients for and understanding the results of these procedures.
1. Stool Sample Analysis:
- Obtain stool samples to rule out other causes of infection, such as bacterial or parasitic infections, especially when diarrhea is present. Follow proper collection and handling protocols.
2. Laboratory Tests Review:
- Complete Blood Count (CBC): Assess for leukocytosis (elevated WBC count), indicating infection, and low hemoglobin levels, suggesting bleeding.
- C-Reactive Protein (CRP): Elevated CRP levels indicate inflammation. Monitor trends in CBC and CRP to assess disease progression and treatment effectiveness.
3. Imaging Procedures:
- Computed Tomography (CT) Scans: The gold standard for diagnosing diverticulitis, CT scans visualize inflamed diverticula, abscesses, and other complications. Prepare patients for CT scans, explaining the procedure and contrast administration if used.
- Barium Enema: While less common now, barium enemas can highlight the colon on X-rays.
- Ultrasonography: Less sensitive than CT scans but can be used to diagnose diverticulitis, though it may miss larger abscesses. Understand the limitations of different imaging modalities.
4. Colon Visualization:
- Colonoscopy: Typically performed 6-8 weeks after symptom resolution to confirm the diagnosis, assess the extent of disease, and rule out other conditions like cancer or inflammatory bowel disease. Educate patients about bowel preparation for colonoscopy and post-procedure care.
- Sigmoidoscopy: Visualizes the sigmoid colon and rectum, common sites for diverticula.
Diverticulitis Nursing Diagnosis and Care Plans
Based on the nursing assessment, several nursing diagnoses may be relevant for patients with diverticulitis. These diagnoses guide the development of individualized care plans to address the patient’s specific needs.
Here are common nursing diagnoses and associated care plan components for diverticulitis:
1. Acute Pain
Nursing Diagnosis: Acute Pain related to the disease process and inflammatory process, as evidenced by reports of abdominal pain/tenderness, guarding behavior, facial grimacing, distraction behavior, diaphoresis, positioning to ease pain, and protective behavior.
Expected Outcomes:
- Patient will verbalize a significant reduction in pain as evidenced by stable vital signs and absence of restlessness and guarding behavior.
- Patient will report pain at a manageable level using a pain scale.
Nursing Interventions:
- Pain Assessment:
- Assess pain characteristics (sharp, constant, sudden), intensity (using a pain scale), and location (typically left lower quadrant).
- Identify precipitating and relieving factors.
- Diagnostic Data Review:
- Monitor results of diagnostic imaging and laboratory studies (elevated WBC, ESR, CRP, CT scan findings).
- Pharmacological Management:
- Administer prescribed antibiotics to address the infectious process.
- Administer analgesics as needed for pain relief. Ensure timely and effective pain medication administration.
- Non-pharmacological Pain Relief:
- Encourage bed rest to reduce intra-abdominal pressure.
- Provide a clear liquid or soft diet as indicated to rest the bowel.
- Implement non-pharmacologic pain relief measures: distraction, music therapy, imagery, relaxation techniques. Integrate both pharmacological and non-pharmacological approaches for comprehensive pain management.
- Surgical Preparation:
- Prepare the patient for surgical intervention if indicated (bowel resection, colostomy). Provide pre-operative education and support.
2. Constipation
Nursing Diagnosis: Constipation related to blockage of the colon, insufficient fiber intake, insufficient fluid intake, inadequate toileting habits, altered routine, decreased physical activity, and habitually suppressing the urge to defecate, as evidenced by straining with defecation, a sensation of anorectal obstruction, a sensation of incomplete evacuation, hard stools, need for manual stool evacuation, inability to defecate, and rectal bleeding.
Expected Outcomes:
- Patient will report passing stool without straining.
- Patient will report at least one bowel movement every 1-3 days.
- Patient will verbalize strategies to manage and prevent constipation.
Nursing Interventions:
- Assessment of Contributing Factors:
- Assess the patient’s fiber and fluid intake.

- Assess the patient’s pattern of defecation and stool characteristics (frequency, consistency, volume, presence of blood or mucus).
- Evaluate stool tests for parasites, infection, toxins, and blood.
- Review CT scan results to confirm diverticulitis and assess severity.
- Monitor for symptoms of dehydration (tachycardia, hypotension, dry mucous membranes, poor skin turgor).
- Pharmacological and Dietary Management:
- Administer prescribed antidiarrheals and antibiotics.
- Place the patient on a liquid diet initially to rest the bowel. Gradually reintroduce solid foods as tolerated.
- Instruct on dietary modifications: decrease fiber intake during diarrhea episodes and increase fiber intake during remission to prevent constipation. Provide clear guidelines on dietary adjustments during different phases of diverticulitis.
- Fluid and Electrolyte Management:
- Monitor the patient’s fluid and electrolyte balance.
- Encourage oral fluid intake or administer IV fluids as prescribed to prevent dehydration. Strict monitoring of intake and output is crucial.
4. Imbalanced Nutrition: Less Than Body Requirements
Nursing Diagnosis: Imbalanced Nutrition: Less Than Body Requirements related to inability to absorb nutrients due to inflammatory response, inability to digest food, abdominal cramping, abdominal pain, constipation, diarrhea, and food intake less than recommended daily allowance (RDA), as evidenced by difficulty swallowing, insufficient dietary intake, inadequate fluid intake, poor appetite, and inadequate knowledge of nutrient requirements.
Expected Outcomes:
- Patient will maintain an average weight and demonstrate stable nutritional status.
- Patient will identify food choices appropriate for diverticulitis management.
- Patient will verbalize understanding of nutritional requirements for diverticulitis.
Nursing Interventions:
- Nutritional Assessment:
- Assess the patient’s nutritional habits and dietary intake.
