title: Hospital admission and mortality differentials of asthma between urban and rural populations in New South Wales.
abstract: It remains unclear whether there are any differentials in hospital admission and mortality rates of asthma between urban and rural populations. An observational study was conducted, based on patient hospital records, to examine the distribution of asthma admissions and mortality in New South Wales. Data on all reported cases of asthma were obtained from New South Wales hospitals between 1989 and 1994. Information on deaths of asthma was collected between 1983 and 1992. The hospital admission rates of asthma varied from 4.8 per 1000 in 1990 to 5.4 per 1000 in 1992 for rural population, and from 3.0 per 1000 in 1991 to 3.4 per 1000 in 1992 for urban population. The hospital admission rates were 51.2-69.1% higher for rural residents than urban dwellers. The mortality rates of asthma ranged from 4.8 per 100,000 in 1983 to 8.0 per 100,000 in 1985 for rural population, and from 3.8 per 100,000 in 1983 to 6.0 per 100,000 in 1989 for urban population. The mortality rates of asthma were 3.62-42.85% higher for rural residents than urban dwellers. These results indicate that the non-age-adjusted hospital admission and mortality rates of asthma were considerably higher in rural populations than in urban populations in New South Wales.
