1. Introduction to Diarrhea in Community Health
Community health nurse performing diarrhea assessment in a rural health setting
Diarrhea remains one of the most common health concerns addressed by community health nurses worldwide. It is characterized by loose, watery stools occurring more than three times in a day, often accompanied by abdominal cramps, nausea, and sometimes fever. Effective diarrhea assessment and management at the community level is crucial for preventing complications, especially dehydration, which can be life-threatening particularly in vulnerable populations like children and the elderly.
From a community health nursing perspective, addressing diarrhea involves more than just treating individual cases; it requires a comprehensive approach including screening, early diagnosis, appropriate treatment, referral when necessary, and most importantly, prevention through education and environmental interventions.
Scope of Diarrhea in Public Health:
- Diarrheal diseases are the second leading cause of death in children under five years worldwide
- Approximately 1.7 billion cases of diarrheal disease occur globally each year
- Preventable and treatable condition when appropriate community interventions are implemented
- Community health nurses serve as frontline providers in identification, management, and prevention
2. Standing Orders for Diarrhea Management
2.1 Definition and Purpose
Standing orders are written protocols approved by a physician or authorized healthcare provider that allow nurses and other healthcare personnel to carry out specific procedures or interventions in certain clinical scenarios without direct physician involvement at the time of care.
Standing orders enable community health nurses to:
- Initiate timely diarrhea assessment and management
- Standardize care approaches in community settings
- Respond promptly to diarrheal cases, reducing complications
- Efficiently utilize healthcare resources in primary care settings

2.3 Implementation in Community Health Settings
When implementing standing orders for diarrhea assessment and management, community health nurses should:
Documentation Requirements
- Record complete patient assessment
- Document interventions provided
- Note patient response to treatment
- Include rationale for any deviation from standing orders
- Maintain community surveillance records
Quality Assurance Measures
- Regular review of standing order implementation
- Periodic updates based on current evidence
- Staff training on proper execution
- Case discussions for complex presentations
- Outcome tracking to evaluate effectiveness
3. Screening and Diagnosis of Diarrhea
3.1 Community-Based Screening Approaches
Effective community screening for diarrheal diseases is essential for early intervention and prevention of outbreaks. Community health nurses should implement the following screening methods:
Active Screening
- Household surveys during regular community visits
- School-based screening programs
- Screening at community gatherings
- Integration with other health programs (e.g., immunization days)
- Enhanced surveillance during seasonal peaks or outbreaks
Passive Screening
- Health facility-based case identification
- Community health worker referrals
- Self-reported cases
- Pharmacy-based surveillance
- School absenteeism monitoring
3.2 Diagnostic Criteria and Tools
The diagnosis of diarrhea in community settings relies primarily on clinical assessment, with laboratory investigations reserved for specific situations.
Clinical Diagnostic Criteria for Diarrhea
Definition: Passage of three or more loose or watery stools in a 24-hour period, with a change in consistency and frequency from normal bowel habits.
Classification by Duration:
- Acute diarrhea: Lasts less than 14 days
- Persistent diarrhea: Lasts 14 days or longer
- Chronic diarrhea: Lasts more than 30 days
Classification by Clinical Presentation:
- Watery diarrhea: Non-bloody, watery stool (typically viral or toxigenic)
- Bloody diarrhea (dysentery): Visible blood in stool (typically bacterial)
- Mucoid diarrhea: Contains visible mucus (may indicate inflammatory process)
Simple Diagnostic Tools for Community Settings
| Diagnostic Tool | Application | Indications |
|---|---|---|
| Visual Stool Assessment | Observing stool consistency, color, presence of blood/mucus | All diarrhea cases; helps classify type of diarrhea |
| Bristol Stool Chart | Standardized tool for categorizing stool consistency | Documentation and communication about stool characteristics |
| Rapid Diagnostic Tests | Point-of-care tests for specific pathogens (e.g., cholera, rotavirus) | Outbreak situations; severe cases; surveillance purposes |
| Dehydration Assessment Chart | WHO guidelines for categorizing dehydration severity | All diarrhea cases to determine treatment approach |
| Occult Blood Testing | Chemical test for non-visible blood in stool | Suspected inflammatory or infectious colitis without visible bleeding |
| Microscopy (if available) | Direct examination for parasites, ova, white blood cells | Persistent cases; suspected parasitic infection |

4. Diarrhea Assessment Framework
4.1 Comprehensive Assessment Protocol
Community health nurses should follow a structured approach to diarrhea assessment. This systematic evaluation helps determine severity, identify causes, and guide appropriate interventions.
History Taking
- Onset and duration of diarrhea
- Frequency and volume of stools
- Stool characteristics (watery, bloody, mucoid)
- Associated symptoms
- Dietary history and recent changes
- Medication use, including antibiotics
- Travel history
- Similar illness in contacts
- Water source and sanitation practices
- Previous episodes and treatments
Physical Examination
- Vital signs (temperature, pulse, respiration, BP)
- Weight (especially for children)
- Hydration status assessment:
- Skin turgor
- Mucous membranes
- Fontanelle in infants
- Capillary refill
- Urine output
- Mental status
- Abdominal examination
- General appearance
Special Assessments
- Nutritional status evaluation
- Immunization history (esp. rotavirus)
- Environmental assessment:
- Water storage practices
- Toilet facilities
- Food preparation areas
- Waste disposal
- Family knowledge assessment
- Care practices observation
- Home hygiene evaluation
4.2 Dehydration Assessment Scale
Assessing dehydration status is critical for appropriate management of diarrhea. The WHO dehydration scale is widely used in community settings:
| Clinical Sign | No Dehydration | Some Dehydration (5-10%) | Severe Dehydration (>10%) |
|---|---|---|---|
| General condition | Alert, responsive | Restless, irritable | Lethargic, unconscious |
| Eyes | Normal | Sunken | Very sunken and dry |
| Tears | Present | Absent | Absent |
| Mouth and tongue | Moist | Dry | Very dry |
| Thirst | Drinks normally | Thirsty, eager to drink | Unable to drink or drinks poorly |
| Skin pinch | Goes back quickly | Goes back slowly | Goes back very slowly (>2 seconds) |
| Radial pulse | Normal | Rapid | Rapid, weak, or not detectable |
| Urine output | Normal | Reduced | Minimal or none |
Key Point: Dehydration Assessment in Special Populations
Modified approach needed for:
- Elderly: May have reduced skin elasticity baseline, assess other signs
- Malnourished children: May already have sunken eyes, use other criteria
- Obese individuals: Skin turgor less reliable, emphasize other signs
- Infants: Include fontanelle assessment (sunken indicates dehydration)
5. Primary Care Interventions
5.1 Rehydration Therapy
Rehydration is the cornerstone of diarrhea assessment and management. The appropriate method and solution depend on the severity of dehydration and patient factors.
Oral Rehydration Therapy (ORT)
For no or some dehydration
WHO ORS Formula:
- Sodium chloride: 2.6g
- Glucose, anhydrous: 13.5g
- Potassium chloride: 1.5g
- Trisodium citrate: 2.9g
- Dissolved in 1 liter of clean water
Administration Guidelines:
- No dehydration: 50-100ml after each loose stool (10ml/kg)
- Some dehydration: 75ml/kg over 4 hours, plus losses
- Give in small amounts frequently
- Use clean cup and spoon (not bottle)
Homemade ORS (emergency):
- 1 liter clean water
- 6 level teaspoons sugar
- 1/2 level teaspoon salt
- Note: Less effective than standard ORS
Intravenous Rehydration
For severe dehydration or when ORT is contraindicated
Indications:
- Severe dehydration (shock, lethargy)
- Persistent vomiting preventing ORT
- Ileus or abdominal distension
- Altered mental status
- Failed ORT administration
Solutions:
- First choice: Ringer’s Lactate
- Alternatives: Normal saline, half-strength Darrow’s solution
Administration Protocol:
- First 30ml/kg within 30 minutes (children) or 60 minutes (adults)
- Reassess and continue until hydration achieved
- Transition to ORT when possible
- Requires immediate referral to higher-level facility
5.2 Nutritional Support
Key Principles of Nutritional Management during Diarrhea
- Continue feeding during illness – “Feed through diarrhea”
- Maintain breastfeeding for infants (increased frequency recommended)
- Return to normal diet as soon as rehydrated
- Provide small, frequent meals of easily digestible foods
- Increase feeding during recovery phase (extra meal daily for 2 weeks)
| Age Group | Recommended Foods | Foods to Avoid |
|---|---|---|
| Infants (0-6 months) |
|
|
| Infants (6-12 months) |
|
|
| Children (1-5 years) |
|
|
| Older children and adults |
|
|
5.3 Medication Management
Caution with Medications
Most cases of acute diarrhea are self-limiting and do not require medication. Inappropriate use of antibiotics can contribute to antimicrobial resistance and may prolong certain infections.
| Medication Category | Indications | Notes for Community Health Nurses |
|---|---|---|
| Zinc Supplementation |
|
|
| Antibiotics |
|
|
| Antimotility Agents |
|
|
| Probiotics |
