title: Hospitalizations for people with type 1 and type 2 diabetes compared with the nondiabetic population of Tayside, Scotland: a retrospective cohort study of resource use.
abstract: OBJECTIVE
  To compare the hospitalizations of people with type 1 and type 2 diabetes with those of the nondiabetic population of Tayside, Scotland.
  
  
  METHODS
  This was a retrospective cohort study set in Tayside, Scotland. Study subjects were eligible for inclusion if they lived in Tayside from 1 January 1995 to 31 December 1995. The primary end point was hospitalization. Comparisons between people with and without diabetes were assessed using logistic regression modeling.
  
  
  RESULTS
  The fixed population for the year 1995 included 366,849 people registered with a Tayside general practitioner; 7,735 (2.1%) of these had diabetes. Approximately 25% of all study subjects with diabetes had at least one hospital admission, compared with 12% of the nondiabetic population. The length of stay was highest for patients with type 2 diabetes (median of 7 days). People with diabetes accounted for 8.2% of the total bed days and had approximately double the risk of admission. Type 2 diabetic patients had increased risks of myocardial infarction and stroke; both type 1 and type 2 diabetic patients were at increased risk for an endocrine/metabolic admission or renal failure. The risk of ophthalmic admissions, especially for cataract, was much higher in patients with type 1 diabetes compared with the nondiabetic population.
  
  
  CONCLUSIONS
  Type 2 diabetes was associated with more frequent and longer admissions compared with the nondiabetic population. This was due to a higher risk of neurological, cardiovascular, renal, and ophthalmic hospitalizations compared with people without diabetes.
