PurposeOn July 1, 2012, the Illinois legislature passed the Save Medicaid Access and Resources Together (SMART) Act, which restricts adult public dental insurance coverage to emergency-only treatment. The purpose of this study was to measure the effect of this restriction on the volume, severity, and treatment costs of odontogenic infections in an urban hospital.Materials and MethodsA retrospective cohort study of patients presenting for odontogenic pain or infection at the University of Illinois Hospital was performed. Data were collected using related International Classification of Diseases, Ninth Revision codes from January 1, 2011 through December 31, 2013 and divided into 2 cohorts over consecutive 18-month periods. Outcome variables included age, gender, insurance status, oral and maxillofacial surgery (OMS) consultation, imaging, treatment, treatment location, number of hospital admission days, and inpatient care level. Severity was determined by the presence of OMS consultation, incision and drainage, hospital admission, and cost per encounter. Hospital charges were used to compare the cost of care between cohorts. Between-patients statistics were used to compare risk factors and outcomes between cohorts.ResultsOf 5,192 encounters identified, 1,405 met the inclusion criteria. There were no significant differences between cohorts for age (P = .28) or gender (P = .43). After passage of the SMART Act, emergency department visits increased 48%, surgical intervention increased 100%, and hospital admission days increased 128%. Patients were more likely to have an OMS consult (odds ratio [OR] = 1.42; 95% confidence interval [CI], 1.11-1.81), an incision and drainage (OR = 1.48; 95% CI, 1.13-1.94), and a longer hospital admission (P = .04). The average cost per encounter increased by 20% and the total cost of care increased by $1.6 million.ConclusionAfter limitation of dental benefits, there was an increase in the volume and severity of odontogenic infections. In addition, there was an escalated health care cost. The negative public health effects and increased economic impact of eliminating basic dental care show the importance of affordable and accessible preventative oral health care.
