Incidence and hospitalization patterns of insulin-dependent diabetes mellitus
HA Fishbein, GA Faich and SE Ellis
Data from a statewide insulin-dependent diabetes mellitus (IDDM) registry
in Rhode Island show that IDDM affects young adults (20-29 yr) as
frequently as adolescents and teenagers (10-19 yr). Overall incidence less
than 30 yr was 14/100,000 population. Peak incidence occurred at 10-14 yr
(19/100,000 population). Poor diabetic control and infection accounted for
46-62% of hospitalizations among 275 known diabetic persons. Despite a
10-yr mean duration of diabetes, only 31% of hospitalized diabetic persons
less than 30 yr of age reported ever having received outpatient diabetes
education of two or more hours. Readmissions 1 yr after initial
registration were more frequent for known (43%) than new-onset (18%) IDDM
cases. Increased risk of readmission for both groups was associated with a
poverty socioeconomic status. Total direct hospitalization costs for IDDM
in persons under 30 yr of age in Rhode Island was $530,000 per year of
$2,245 per patient.
