Types of usual sources of care and their association with healthcare outcomes among cancer survivors: a Medical Expenditure Panel Survey (MEPS) study

Abstract

Purpose : To assess associations between usual source of care (USC) type and health status, healthcare access, utilization, and expenses among adult cancer survivors. Methods: This retrospective cross-sectional analysis using 2013–2018 Medical Expenditure Panel Survey included 2690 observations representing 31,953,477 adult cancer survivors who were currently experiencing cancer and reporting one of five USC types: solo practicing physician (SPP), a specific person in a non-hospital facility, a specific person in a hospital-based facility, a non-hospital facility, and a hospital-based facility. We used logistic regressions and generalized linear models to determine associations of USC type with health status, healthcare access, utilization, and expenses, adjusting for patient demographic and clinical characteristics. Results: All non-SPP USC types were associated with reporting more difficulties contacting USC by telephone during business hours (p < 0.05). Compared to SPP, non-hospital facility was associated with more difficulty getting needed prescriptions (OR: 1.81, p = 0.036) and higher annual expenses ($5225, p = 0.028), and hospital-based facility was associated with longer travel time (OR: 1.61, p = 048), more ED visits (0.13, p = 0.049), higher expenses ($6028, p = 0.014), and worse self-reported health status (OR: 1.93, p = 0.001), although both were more likely to open on nights/weekends (p < 0.05). Cancer survivors with a specific person in a hospital-based facility (vs. SPP) as USC were > twofold as likely (p < 0.05) to report difficulty getting needed prescriptions and contacting USC afterhours. Conclusions: Among adult cancer survivors who were currently experiencing cancer, having a non-SPP type of UCS was associated with reporting more difficulties accessing care, worse health, more ED visits, and higher total expenses. Implications for Cancer Survivors: Transitioning to SPP type of USC may result in better healthcare outcomes.
