<i>Objective</i>: This study aims to describe
differences in healthcare utilization between homeless and non-homeless minors with
diabetes mellitus (DM).
<p><i>Research Design and Methods</i>: Data from
the Healthcare Cost and Utilization Project’s Statewide Inpatient Database from
New York for years 2009-2014 was examined to identify pediatric patients <18
years old with DM. Outcomes
of interest included: hospitalization rate, in-hospital mortality, admission
through the emergency department (ED), diabetic ketoacidosis (DKA),
hospitalization cost, and lengths of stay (LOS). Other variables of
interest included: age group, race/ethnicity, insurance type, and year. Multivariate
logistic regression models were used for in-hospital mortality, admission through ED, and DKA.
Log-transformed linear regression models were used for hospitalization cost,
and negative binomial regression models were used for LOS.</p>
<p><i>Results</i>: A total of 643
homeless and 10,559 non-homeless cases were identified. The hospitalization
rate was higher among homeless minors, with 3.64 per 1,000 homeless population
and 0.38 per 1,000 non-homeless population, respectively. A statistically
significant higher readmission rate was detected among homeless minors (20.4%
among homeless and 14.1% among non-homeless, <i>p</i> <0.01). Lower rates of DKA (OR 0.75, <i>p</i>=0.02), hospitalization costs (point estimate 0.88,<i> p</i> <.01), and longer LOS (Incidence
Rate Ratio (IRR) 1.20, <i>p</i> <0.01)
were detected among homeless minors compared to non-homeless minors. </p>
<p><i>Conclusions</i>: This study found
that among minors with DM, those who are homeless experience a higher
hospitalization rate than the non-homeless. Housing instability, among other environmental
factors, may be targeted for intervention to improve health outcomes.</p>
