Findings indicate that having insurance was associated with decreased emergency care use and increased access to routine medical care. In comparison with insurance status, medical need was a more important determinant of the frequency of both routine and emergency medical care visits. Researchers conclude that the results broadly support Medicaid expansion under the Affordable Care Act, as well as its provisions for medical homes for offender populations. Multivariable logistic and negative binomial models controlling for socio-demographic and psychodiagnostic factors assessed the extent to which insurance status and medical need significantly affected having a regular health care place/provider and number of emergency and non-emergency care visits in the year prior to detention. 46 references (Publisher abstract modified)
