Abstract
Over a 10-mo period, a computerized admission discharge system was scrutinized to identify all persons with diabetes mellitus admitted to a general hospital in Christchurch, North Canterbury (population 342,000), New Zealand. The 274 admissions by 197 diabetic persons (42% were insulin treated, 14% were newly diagnosed, 44% were non-insulin-dependent) contributed to 3.6% of the total hospital admissions, with duration of stay being longer than for nondiabetic persons (13.6 versus 11.3 days, P = 0.05). Patients admitted were aged 11–91 yr (mean 59 yr); those over 50 yr of age were numerically the largest admission group. Although cardiovascular illnesses were the most frequent events precipi-tating admission (34%), potentially preventable admissions for reasons of infection, poor glycemic control, or hypoglycemia were found in all age groups. Just under half of the 902 registered insulin-treated diabetic patients living in this health region had at some stage participated in diabetes education programs at the time this admission survey was undertaken. Of these, only nine were admitted. The other 70 insulin-treated patients admitted who lived in this region had never had diabetes education. Overall, only 11.7% of patients admitted had received diabetes education. These data show that, for insulin-treated diabetic individuals at least, admission rates were substantially lower among those who were sufficiently motivated to attend diabetes education programs.
