Trends in admission and case fatality for acute malnutrition: Kingston 1892-1991

RESUMO

The case fatality ratio (CFR) in acute protein-energy malnutrition (PEM) achieved in the Tropical Metabolism Research Unit (TMRU) was compared with that of other tertiary care facilities in Kingston. Trends in admission and fatality rates, case severity and complications were also examined. From ward admission registers for Bustamante Hospital for Children (BHC), the University Hospital of the West Indies (UHWI), children's wards and the TMRU all cases of PEM admitted from 1982 through 1991 were enumerated and there was a docket search for random subsamples. Ten-year mean CFR percent for BHC was 8.8 (n=1974); for UHWI wards 5.5 (n=658); for TMRU 7.1 (n=662). BHC has the least restrictions on admission and showed most clearly that the peak time in Kingston for admission of PEM was around 1985, falling to a minimum in 1988 - 1990 and rising again in 1991; however, the other sites also showed similar trends. BHC had a range of CFR precent p.a. of 20.0 to 3.0, with a striking fall in the second half of the decade. There was no temporal CFR trend for the UHWI or TMRU. The latter institution had the highest proportion of admissions with marasmic-kwashiorkor and the lowest proportion with recorded infection. The annual variation in numbers of PEM deaths at BHC was best accounted for by (a) percentage change in consumer price index and (b) percentage change in the US$ value of the Jamaican $, in the preceding year, and (c) annual number of admissions, together. Generally, our findings suggest a minor role for expert in-patient management in reducing deaths from PEM
