Association of a Patient's Type of Insurance With Preventive Service Delivery

Introduction Chronic disease or death associated with chronic disease is often avoidable with proper interventions, including preventive services in healthcare settings. However, preventive service delivery rates by physicians are low. This study examined the association between preventive services and the type of patient insurance, as well as the association between the duration of an office visit and the type of patient insurance. Methods A retrospective observational cohort study was conducted using multivariate logistic regression. Pooled data on physician office-based visits from the 2011-2016 and 2018 National Ambulatory Medical Care Survey (NAMCS) were used in this analysis. The main measures observed were the odds of providing preventive services as they related to the type of patient insurance. Preventive measures assessed were those recommended by the United States Preventive Services Task Force with an A or B grade, applicable to most adults 18-64. Additionally, the mean office visit duration was analyzed based on the type of insurance. Results The odds of receiving cervical cancer screenings and tobacco smoking cessation screenings were 47% (p <0.01) and 31% (p =0.10) lower with Medicaid than private insurance, respectively. The odds of receiving blood pressure screenings and cervical cancer screenings were 43% (p =0.01) and 62% (p <0.01) lower in uninsured office visits compared to private insurance, respectively. Compared to private insurance, Medicaid and uninsured visits were 2.68 minutes and 1.97 minutes shorter in duration, respectively (p <0.05). Conclusions An association was found between the type of patient's insurance and the odds of providing preventive services. If the aim of healthcare is to improve the incidence of chronic disease or death associated with chronic disease, preventive services should be provided regardless of insurance type.
