The effect of routine hospital care on the health of hypothermic newborn infants in Zambia.

A prospective cohort study was carried out at the University Teaching Hospital, Lusaka, Zambia, to investigate the prevalence of neonatal hypothermia, type of infant care and incidence of mortality. Two-hundred-and-sixty-one infants, aged 0-7 days, admitted to the pediatric unit during the 'warm' season were recruited to the study. Forty-four per cent of the infants were hypothermic (< 36 degrees C) on admission, and admission hypothermia correlated to admission weight and home delivery in the youngest age group (0-24 hours). Exclusively breastfed infants (age group 1-7 days) were less likely to be hypothermic at admission. 'Hypothermia' was not recorded as an admission diagnosis and no special attention was given to those infants in terms of clinical management. Mean time to reach a body temperature above 35.9 degrees C did not differ between infants kept in a cot and in an incubator. Total numbers of death was 82 (31 per cent) and the mortality was higher in infants who were hypothermic at admission compared to those who were not. This study demonstrates that a change of existing care routines is needed.
