Trends in hospitalizations and mortality due to medicinal or non-medicinal poisonings in Hong Kong

Previous epidemiologic studies of poisonings in Hong Kong are regional hospital- or poison information center-based and have focused on either adults or children. This paper reports on the territory-wide hospitalization and mortality rates, comparing medicinal and non-medicinal poisonings in the general population. Between 1980 and 1995, the figures far hospitalizations and mortality due to medicinal (ICD codes 960-977) or non-medicinal (ICD codes 980-989) poisonings were obtained from the Annual Reports of the Department of Health, Hong Kong Government. Rates of medicinal poisonigs increased between 1980/81 [57.3/100,000] and 1987/88 (80.9/100,000), but then declined (59.1/100,000) in 1993/94. Rates of non-medicinal poisonings were rather static (49-53/100,000) between 1980/81 and 1988/89, but then declined (22.0/100,000) in 1994/95, Between 1980/81 and 1988/89, rates of fatal medicinal poisonings (0.73-1.31/100,000) were similar to those of fatal non-medicinal poisonings (0.98-1.70/100,000). However, from 1989/90, there was an increase in the rates of fatal medicinal poisonings (1.94-2.80/100,000), although rates for non-medicinal poisonings remained much the same (0.80-1.38/100,000). Hospitalizations due to poisonings are now less common in Hong Kong than before, due largely to a greater decline in non-medicinal poisonings.
