Serious unintentional injuries associated with architectural glass.

Injuries associated with architectural glass have become a matter of considerable concern in recent years. Despite this concern there has been no attempt to document either the extent of the problem in New Zealand or the circumstances under which these events occur. In this study, national injury mortality data for the period 1977-86 were examined and cases selected if the cause of death was attributable to an event involving architectural glass. A total of nine deaths were identified. All discharges from New Zealand public hospitals during 1986 were examined to identify victims who had been treated for injuries associated with architectural glass. Descriptive information contained on each patient record was coded to provide more specific information on the circumstances of injury. A total of 501 first admissions to hospital were identified, giving an incidence rate of 15 per 100,000 persons per year. The highest rate of 60 per 100,000 per year, was found for males in the age group 15-24 years. Seventy-eight percent of the events involved males, 62% occurred at home, 64% involved windows, and 32% involved doors. Ninety-three percent of the injuries were open wounds. Seventy-nine percent of the injuries were to the upper limbs, 13% were to lower limbs and 5% were to the head. The mean length of stay in hospital was 3.3 days. Opportunities for injury prevention are discussed including visual and physical barriers, mandatory glazing standards and public education. Specific areas requiring further research are identified.
