Increasing trend of outpatient management of children with newly diagnosed IDDM. Colorado IDDM Registry, 1978-1988.

OBJECTIVE--To examine the management of newly diagnosed insulin-dependent diabetes mellitus (IDDM) in Colorado over time and to determine the prevalence of outpatient care at IDDM diagnosis on a statewide basis. RESEARCH DESIGN AND METHODS--The Colorado IDDM Registry was used to assess medical care at the diagnosis of IDDM in 1182 patients less than 18 yr of age between 1978 and 1988. RESULTS--Twenty-three percent of children with IDDM in Colorado reported never being hospitalized during the diagnosis period. Treatment of IDDM at diagnosis (outpatient vs. inpatient) did not differ by age, sex, or ethnicity/race. Patients living in rural counties were less likely to have been treated as outpatients at diagnosis than those living in urban counties. Physicians at specialized diabetes clinics (e.g., The Barbara Davis Center for Childhood Diabetes and The Childrens Hospital) were more likely to treat newly diagnosed children in an outpatient setting than physicians not affiliated with these clinics. The proportion of patients receiving only outpatient care at IDDM diagnosis increased from 6% in 1978 to 35% in 1988. This increase can be attributed to three factors: 1) an increase in the number of Colorado children diagnosed at The Barbara Davis Center, where outpatient care is strongly advocated; 2) a change in treatment practices at The Childrens Hospital away from routine hospitalization at onset; and 3) a steady increase in outpatient care for newly diagnosed diabetic children by physicians who were not affiliated with the aforementioned specialized diabetes clinics. CONCLUSIONS--The relatively new practice of outpatient care at diagnosis of IDDM increased between 1978 and 1988 in Colorado, in both specialized diabetes clinics and physicians' practices not affiliated with specialized clinics.
