Abstract
In1993, theWorldHealth Organization completed thedevelopment ofadraft algorithm fortheintegrated management ofchildhood illness (IMCI), which deals with acute respiratory infections, diarrhoea, malaria, measles, earinfections, malnutrition, andimmunization status. Thepresent study compares theperform- anceofaminimally trained health worker tomakeacorrect diagnosis using thedraft IMCIalgorithm with that ofafully trained paediatrician whohadlaboratory andradiological support. During the14-month study period, 1795children agedbetween 2months and5yearswereenrolled fromtheoutpatient paediatric clinic ofSiaya District Hospital inwestemKenya; 48%werefemale andthe median agewas13months. Fever, coughanddiarrhoea werethemostcommonchief complaints presented by907(51%), 395(22%), and199(11%) ofthechildren, respectively; 86%ofthechief complaints were directly addressed bytheIMCIalgorithm. A total of1210children (67%)hadPlasmodium falciparum infection and1432(80%) mettheWHOdefinition foranaemia (haemoglobin <11gidl). Thesensitivities and specificities forclassification ofillness bythehealth worker using theIMCIalgorithm compared todiagnosis bythephysician were:pneumonia (97%sensitivity, 49%specificity); dehydration inchildren with diarrhoea (51%,98%); malaria (100%, 0%);earproblem (98%,2%);nutritional status (96%,66%); andneedfor referral (42%,94%). Detection offever bylaying ahandontheforehead wasbothsensitive andspecific (91%, 77%). There wassubstantial clinical overlap between pneumonia andmalaria (n=895), andbetween malaria andmalnutrition (n= 811). Basedontheinitial analysis ofthese data, somechanges weremadeintheIMCIalgorithm. This study provides important technical validation oftheIMCIalgorithm, buttheperformance ofhealth workers should bemonitored during theearly partoftheir IMCItraining.
