Introduction And Rationale

  • Definition: IMNCI is an integrated approach to child health that focuses on the well-being of the whole child, rather than a single disease entity. It is a syndromic case management approach developed by WHO and UNICEF, designed to reduce death, illness, and disability, and to promote improved growth and development among children under five years of age.
  • Core Rationale: In developing countries, the majority of childhood deaths are caused by five preventable/treatable conditions: acute respiratory infections (pneumonia), diarrhea, measles, malaria, and malnutrition. Children often present with overlapping signs and symptoms (e.g., a child with malaria and pneumonia simultaneously), making single-disease diagnosis difficult for frontline workers. IMNCI provides an evidence-based, syndromic triage system.

Differences Between Generic WHO IMCI And Indian IMNCI

The Government of India adapted the generic IMCI to suit the national epidemiological profile, creating IMNCI. Key Indian adaptations include:

  • Inclusion Of Early Neonatal Period: Generic IMCI covers children 1 week to 5 years. Indian IMNCI covers infants from 0 days to 2 months (Young Infant) and 2 months to 5 years (Child). This was crucial because over 50% of infant mortality in India occurs in the neonatal period.
  • Addition Of Malaria And Anemia: Aligned with the National Vector Borne Disease Control Programme (NVBDCP) guidelines.
  • Dengue Hemorrhagic Fever: Added to the algorithm due to endemicity.
  • Malnutrition Assessment: Integrated with the use of MUAC (Mid-Upper Arm Circumference) and WHO Z-score growth charts.
  • Management Of Young Infants: Expanded to include comprehensive assessment of bacterial infections, jaundice, and breastfeeding counseling.

The Case Management Process

The IMNCI strategy utilizes a sequential, structured case management process for every sick child:

  1. Assess: Take a history, check for danger signs, and perform a focused physical examination (Ask, Look, Listen, Feel).
  2. Classify: Based on the presence or absence of specific signs, classify the illness into color-coded categories.
  3. Identify Treatment: Determine the specific treatments needed for the classification.
  4. Treat: Administer pre-referral drugs, perform procedures, or teach the mother how to give treatment at home.
  5. Counsel The Mother: Provide advice on feeding, fluids, and when to return immediately.
  6. Follow-up: Reassess the child at specified intervals.

Color Coding And Triage System

IMNCI uses a universal three-tier color-coded triage system to guide immediate action.

Color CodeUrgencyAction Required
PINK (Severe)UrgentRequires Urgent Referral to a higher facility. Administer pre-referral treatment (e.g., first dose of antibiotics, prevention of hypoglycemia) before transfer.
YELLOW (Moderate)ActionSpecific medical treatment and advice. Can be managed at the Outpatient/PHC level with prescribed oral drugs and close follow-up.
GREEN (Mild)SafeSimple advice and home care. Management by the caregiver at Home.

Part 1: Management Of The Sick Young Infant (0 Up To 2 Months)

The assessment of the young infant involves checking for Possible Severe Bacterial Infection (PSBI), jaundice, diarrhea, and feeding problems.

Part 2: Management Of The Sick Child (2 Months Up To 5 Years)

1. Check For General Danger Signs

Before assessing specific symptoms, ALWAYS check for General Danger Signs. The presence of ANY general danger sign automatically classifies the child into a PINK (Urgent Referral) category.

Pre-Referral Treatment Principles

When a child is classified in the PINK category, immediate life-saving interventions must be provided before transfer to prevent mortality during transit.

  • First Dose of Appropriate Antibiotic: Usually IM Ampicillin + Gentamicin for infants, or IM Ceftriaxone.
  • Prevention of Hypoglycemia: Administer 50 ml of 10% Glucose solution or breastmilk orally/via NG tube.
  • Artesunate: IM Artesunate for severe febrile illness in high-risk malaria areas.
  • Diazepam/Midazolam: PR Diazepam or IM Midazolam for actively convulsing children.
  • Vitamin A: Immediate dose for severe complicated measles or severe malnutrition with eye signs.

Counseling The Mother

IMNCI places heavy emphasis on empowering the caregiver. Counseling encompasses:

  1. Assess the Child’s Feeding: Ask about breastfeeding frequency, complementary foods (consistency, frequency, active feeding).
  2. Feeding Recommendations: Promote exclusive breastfeeding up to 6 months, and introduction of nutrient-dense complementary foods at 6 months while continuing breastfeeding up to 2 years.
  3. Fluid Requirements During Illness: Advise the mother to increase fluid intake (including breastmilk) to prevent dehydration.
  4. When to Return Immediately:
    • Any sick child: Not able to drink/breastfeed, becomes sicker, develops a fever.
    • Child with Cough: Develops fast breathing or difficult breathing (chest indrawing).
    • Child with Diarrhea: Blood in stool or drinking poorly.

Follow-Up Guidelines

Crucial for cases classified as YELLOW.

  • 2 Days: Pneumonia, Dysentery, Malaria (if fever persists), Local bacterial infection, Feeding problem.
  • 3 Days: Measles with eye/mouth complications.
  • 5 Days: Persistent diarrhea, Acute ear infection, Cough/cold not improving.
  • 14 Days: Malnutrition (MAM), Anemia, Low weight for age.

F-IMNCI (Facility Based IMNCI) Integration

While IMNCI is designed for outpatient and peripheral centers, F-IMNCI is the protocol for inpatient hospital management of children referred with PINK classifications. It details:

  • Emergency Triage Assessment and Treatment (ETAT): Sorting patients into Emergency signs (ABCDE approach), Priority signs, and Non-urgent cases.
  • Inpatient Management: Standardized protocols for treating severe pneumonia, SAM with medical complications (at NRCs), severe malaria, and neonatal sepsis in the ward setting.
