Abstract: | This paper describes the analysis of injury-related linked hospital morbidity data by admissions and by individual patients in Western Australia (WA) from 1990 to 1994. Over this five-year period, there were an average of 35,385 admissions and 30,524 people admitted each year for injuries in WA. The age-standardised rates for injury-related hospital admissions and persons admitted for injuries increased significantly, by 2.4% and 1.5% per year respectively, over the five-year period. The number of admissions and the number of persons admitted peaked in the 20–24 years age group but the highest rates were among those aged 75 years and above. Injuries accounted for nearly 10% of all hospital bed day costs and cost about $50 per head of population per year. The cost of hospitalisation rose steadily from $85.2 million in 1990 to $113.6 million in 1994, the average cost being nearly $100 million per year. The average cost per injury related hospital episode was $2,748. Generally, the cost per hospital episode was higher for males and increased with age, following a similar pattern to that for the average length of stay. |
