Trends in perinatal mortality at a Hong Kong hospital

Abstract
Causes of perinatal mortality in Tsan Yuk Hospital, Hong Kong, were classified into 14 categories from the P list of stillbirths and neonatal mortality in the International Statistical Classification of Diseases, Injuries and Causes of Death. Trends for each category over the period 1970-1979 were examined by regression analysis. Overall perinatal mortality fell from 17.80 in 1970 to 10.94 in 1979. A low incidence of deaths from congenital abnormality and medical complication in the mother was observed. Significant statistical correlations were obtained in the trends in mortality associated with placental hemorrhage, pre-eclampsia, difficult labor, hemolytic disease of the newborn, and prematurity. Improvements in perinatal mortality in these areas and inadequacies in perinatal care in other areas are discussed.
