Abstract: | By referring to all of the death cards recorded for the year of 1978 in the whole area of Osaka Prefecture, we examined deaths due to burn injuries, electric injury and heatstroke, and obtained the following results. - 1. 1. Of the total 41 737 deaths, externally induced death took place in 3207 cases (8 per cent), and death due to burn injuries including electric shock and heatstroke took place in 215 cases (2–60 cases against 100 000 population), accounting for 6.7 per cent of all externally induced deaths. In those aged under 40 years, externally induced death ranked highest as the cause of death, and burn injury was one of the chief causes.
- 2. 2. The sex ratio of burn-induced death was 3: I for males and females, respectively. However, if burn injuries resulting from social factors and suicide were excluded, the sex ratio was not significantly different at 1-3:1. The causes of injury were work accidents, suicide and other accidents at a rate of I: 2: 3.
- 3. 3. The monthly incidence of injuries was larger in winter when there were many cases of on-the-spot death due to fire, but there was no significant difference in the monthly incidence of post-treatment death.
- 4. 4. Of the 215 cases, 158 (73–5 per cent) died on the spot, while only 57 cases died after treatment. There were apparent regional differences in the total casualties. Post-treatment death probably occurred in 30 per cent of the total deaths induced by burn injuries.
- 5. 5. Medical institutions receiving burn victims could be divided into private and public ones at a nearly equal ratio. Public institutions took a significantly larger proportion of this type of casualty than following road accidents.
- 6. 6. Supplementary investigations revealed that two to three times as many people died at the scene of the accident than died after treatment from severe burns, this amounted to 140 cases a year in the whole area of Osaka Prefecture.
