ObjectivesThe prevalence and burdens of obesity-associated chronic conditions (OCC) are rising nationwide, particularly in health professional shortage areas (HPSA). This study examined the impact of access to primary care on health care utilization for vulnerable populations with OCC in the South.MethodsAdult patients with obesity (BMI ≥ 30 kg/m2 ), greater than or equal to one additional OCC, and self-reported primary care access data were retrospectively identified from hospital and emergency department (ED) electronic medical records of a major health care system in the South. Multivariable logistic regression assessed factors associated with self-reported access to primary care. Multivariable zero-inflated negative binomial models assessed effect of HPSA residence on relationships between self-reported access to primary care and health care utilization.ResultsA total of 29 674 patients were identified. Hypertension (76.1%), type 2 diabetes mellitus (34.1%), and hyperlipidemia (32.9%) were the most prevalent OCC. Males (odds ratio [OR]: 0.43; 95% confidence interval [CI], 0.40-0.47), unmarried (OR: 0.69; 95% CI, 0.63-0.76), and uninsured (OR: 0.29; 95% CI, 0.27-0.32) had lower odds of access to primary care. For patients living in HPSA (vs non-HPSA), access to primary care was associated with higher incidence of overall ED use (relative risk [RR]: 1.38; 95% CI, 1.19-1.61) and lower incidence of potentially preventable hospital use (RR: 0.59; 95% CI, 0.38-0.92).ConclusionParadoxically, access to primary care may increase ED use while reducing potentially preventable hospital utilization for patients with OCC in HPSA. Increasing access to primary care alone, without strengthening its capacity to serve the needs of vulnerable patients, may be insufficient to reduce hospital utilization.© 2020 John Wiley & Sons, Ltd.
