Cost-related nonadherence by medication type among Medicare Part D beneficiaries with diabetes.

摘要: Only about 50% of patients with chronic conditions routinely take their medicine as directed [1]. Diabetic patients’ nonadherence to medication is associated adverse health outcomes, including increased hospitalization rates and higher mortality [2-6]. Patients report many reasons for such forgetfulness, desire avoid side effects, the relatively high costs some medications [2]. Efforts increase overall adherence often focus specifically on decreasing cost-related because it common can be addressed policy-based approaches. Cost-related (CRN) among older adults has been documented prior initiation Medicare Part D program remains a significant problem, recent published estimates CRN ranging from 13% 36% [7-10]. The existing research somewhat limited, vast majority papers examining have used administrative data calculate adherence, rather than direct patient report. Most these also observed responses cost sharing changes in copayment or prescription tiering strategies, infer indirectly that out pocket [11-16]. Some authors found people are more likely cut back they consider “less” necessary which an over-the-counter substitution readily available [17-18]. However, while other studies directly asked types use less due (e.g., anti-hypertensives, cholesterol-lowering medications), shows do not fact know indication all [19]. Few reconciled pharmacy actual bottles patient’s possession determine adults. Using collected part Translating Research into Action Diabetes (TRIAD) Study, main objective this analysis examine rate self-reported population persons diabetes who entered coverage gap 2006. Data were obtained during telephone interviews bring phone, self-report any currently taking. In group elderly beneficiaries diabetes, we hypothesized would treating (diabetes, blood pressure, cholesterol) primarily symptom relief. We simultaneously investigated possibility beneficiaries’ socio-demographic characteristics. In particular, having income will make after controlling factors.
