Abstract
In order to discover differences that may exist in death rate and utilization pattern of the deaths during hospital admission between insured and non-insured patients, records for all hospital deaths discharged between January 1978 to December 1980 from a university hospital were examined. The major findings were as follows; 1. Total number of deaths in the hospital showed no difference by year, however, the percentage of insured patients was increased year by year. 2. The death rate during hospital admission was higher among non-insured patients and statistically significant. Age specific death rates were higher among non-insured patients and statistically significant except the age group 1-4. 3. The case mix among the hospital deaths was different between the insured and the non-insured. 4. Length of stay was statistically significantly longer among the insured. However, surgical operation rate and the period from surgical operation to death showed no difference between the two groups. 5. The non-insured patients were admitted more through the emergency room than insured patients.
