Insights
The Integrated Management of Neonatal and Childhood Illness (IMNCI) algorithm showed moderate agreement with pediatrician decisions in India, with significant over-diagnosis of severe illness in infants with multiple symptoms.
Area of Science:
- Pediatrics
- Public Health
- Global Health
Background:
- The Integrated Management of Neonatal and Childhood Illness (IMNCI) strategy is widely implemented in India.
- Limited studies have validated IMNCI's accuracy against expert pediatrician decisions within the Indian context.
Purpose of the Study:
- To compare IMNCI diagnostic decisions with those of pediatricians for sick young infants.
- To evaluate the agreement, over-diagnosis, and under-diagnosis rates of the IMNCI algorithm.
- To assess the impact of multiple presenting symptoms on IMNCI classifications.
Main Methods:
- A comparative study involving sick young infants presenting to a pediatric department.
- Analysis of IMNCI algorithm decisions versus pediatrician assessments.
- Statistical evaluation using percent agreement, Kappa, and weighted Kappa.
Main Results:
- Overall diagnostic agreement between IMNCI and pediatricians was 55.56% (Kappa=0.32).
- The IMNCI algorithm demonstrated a 33.33% over-diagnosis and 11.11% under-diagnosis rate.
- IMNCI significantly over-classified infants with multiple symptoms as 'red' (71.88%) compared to single symptoms (40%).
Conclusions:
- The IMNCI algorithm shows moderate diagnostic agreement with pediatricians for sick young infants in India.
- Over-diagnosis, particularly in cases with multiple symptoms, is a notable finding.
- Further refinement of the IMNCI algorithm may be needed to improve accuracy and reduce unnecessary referrals.
Abstract:
Integrated management of neonatal and childhood illness (IMNCI) was already operational in many states of India, but there were very few studies in Indian scenario comparing its validity and reliability with the decisions of pediatricians. The general objective of the study is to compare the IMNCI decisions with the decisions of pediatricians and the specific objectives are to assess the agreement between IMNCI decisions and the decisions of pediatricians, to assess the under diagnosis and over diagnosis in IMNCI algorithm in comparison to the decisions of pediatricians and to assess the significance of multiple presenting symptoms in IMNCI algorithm. The study was conducted among the sick young infants presenting in pediatric department from January to March 2009. The IMNCI decision was compared with pediatrician's decisions by percent agreement, Kappa and weighted Kappa with the aids of SPSS version 10. The overall diagnostic agreement between IMNCI algorithm and pediatrician's decisions was 55.56%, (Kappa 0.32 and weighted Kappa 0.41) with 33.33% over diagnosis, and 11.11% under diagnosis. 71.88% young infants with multiple symptoms and 40% with single symptom were classified as red by IMNCI algorithm, which is statistically significant (P=0.004) whereas 56.25% young infants with multiple and 31.76% with single symptom were considered admissible by pediatricians, which is not statistically significant (P=0.052).
