In 1993, the World Health Organization completed the development of a draft algorithm for the integrated management of childhood illness (IMCI), which deals with acute respiratory infections, diarrhoea, malaria, measles, ear infections, malnutrition, and immunization status. The present study compares the performance of a minimally trained health worker to make a correct diagnosis using the draft IMCI algorithm with that of a fully trained paediatrician who had laboratory and radiological support. During the 14-month study period, 1795 children aged between 2 months and 5 years were enrolled from the outpatient paediatric clinic of Siaya District Hospital in western Kenya; 48% were female and the median age was 13 months. Fever, cough and diarrhoea were the most common chief complaints presented by 907 (51%), 395 (22%), and 199 (11%) of the children, respectively; 86% of the chief complaints were directly addressed by the IMCI algorithm. A total of 1210 children (67%) had Plasmodium falciparum infection and 1432 (80%) met the WHO definition for anaemia (haemoglobin < 11 g/dl). The sensitivities and specificities for classification of illness by the health worker using the IMCI algorithm compared to diagnosis by the physician were: pneumonia (97% sensitivity, 49% specificity); dehydration in children with diarrhoea (51%, 98%); malaria (100%, 0%); ear problem (98%, 2%); nutritional status (96%, 66%); and need for referral (42%, 94%). Detection of fever by laying a hand on the forehead was both sensitive and specific (91%, 77%). There was substantial clinical overlap between pneumonia and malaria (n = 895), and between malaria and malnutrition (n = 811). Based on the initial analysis of these data, some changes were made in the IMCI algorithm. This study provides important technical validation of the IMCI algorithm, but the performance of health workers should be monitored during the early part of their IMCI training. The World Health Organization (WHO) in 1993 developed the integrated management of childhood illness (IMCI) draft algorithm which offers guidelines upon the diagnosis and treatment of acute respiratory infections, diarrhea, malaria, measles, ear infections, and malnutrition, as well as immunization status. During a 14-month study period, 1795 children aged 2 months to 5 years were enrolled in the study from the outpatient pediatric clinic of Siaya District Hospital in western Kenya, of whom 52% were male and the median age was 13 months. 51% of the children complained of having fever, 22% of having a cough, and 11% of having diarrhea. 86% of the main complaints were directly addressed by the IMCI algorithm. 1210 children had Plasmodium falciparum infection and 1432 met the WHO definition for anemia. The sensitivities and specificities for classification of illness by a minimally trained health worker using the IMCI algorithm compared to diagnosis by the physician were: pneumonia, 97% sensitivity and 49% specificity; dehydration in children with diarrhea, 51% and 98%, respectively; malaria, 100% and 0%; ear problem, 98% and 2%; nutritional status, 96% and 66%; and need for referral, 42% and 94%. Detection of fever by placing a hand upon the forehead was 91% sensitive and 77% specific. Considerable clinical overlap was observed between pneumonia and malaria, and between malaria and malnutrition. Study findings led to some changes in the IMCI algorithm. |
