Hospital admissions due to acute poisoning in the New Territories, Hong Kong.

To study the pattern of acute poisoning in the New Territories East of Hong Kong, 291 adult cases admitted to the Prince of Wales Hospital in 1989 were reviewed. The female-to-male ratio was 2.3 to 1 and the majority of patients (83%) were below the age of 40. The main poisons involved were hypnotics and sedatives (44.3%), household products (14.8%) and analgesics (10%). The poisoning was intentional in the majority of cases (98.6%). A specific antidote was necessary in 5.2% of cases. Four patients died after admission giving an overall mortality of 1.4%. When compared to the findings from other western countries, important variations in the pattern of acute poisoning were seen in Hong Kong. Firstly, a substantial proportion of drugs ingested were not dispensed labeled although their nature could usually be determined. Secondly, "Dettol", a household antiseptic, was commonly used in self-poisoning episodes. The lack of drug identification labeling on dispensed medicines outside hospitals is of great concern to all physicians in Hong Kong.
