Item The intention to enroll in Medicare Part D:an analysis in the pre-medicare eligible population(2012-01) Jin, TaoStudies suggested that the wide range of drug plan options and the complexity of drug benefits in the Medicare Part D program might have discouraged the enrollment in the Medicare Part D program. This study used the Theory of Planned Behaviors (TPB) as the theoretical framework to understand pre-Medicare eligible individuals’ decisionmaking in the context of Medicare Part D enrollment. Specifically, the objective of this research were (1) to examine correlations between underlying beliefs with attitudes, subjective norms, and perceived behavioral controls variables in the model of the TPB; and (2) to evaluate the strengths of paths among attitudes, subjective norms, perceived behavioral controls, and intentions to enroll in the model of the TPB. This research included focused interviews, pretest study, pilot study, and main study. The instrument was established and evaluated in focused interviews, pretest study, and pilot study. Then a cross-sectional survey design was used in the main study and data was collected by mailed self-administered surveys. The survey was administered to a random sample of 1500 pre-Medicare eligible individuals (62-64 years) living in Minnesota. 689 surveys were returned; 556 out of these 689 surveys were eligible for inclusion criteria. The usable response rate was 40.67%. Descriptive statistics showed that generally pre-Medicare eligible individuals’ evaluations about Medicare Part D (Average score: 3.25 out of 5); their social pressure to enroll in Medicare Part D (Average score: 3.26 out of 5), and their perceived controllability (Average score: 3.34 out of 5) regarding the Medicare Part D enrollment were positive. In addition, their intention to enroll in Medicare Part D was moderately positive (Average score: 3.33 out of 5). Hierarchical regression analyses were employed to explore correlations between underlying beliefs (behavioral beliefs, normative beliefs, and control beliefs) and corresponding factors (attitudes, subjective norms, and perceived behavioral controls) preceding enrollment intentions. The results revealed that (1) “saving money on medications” (a=1.79, p<0.0001) was significantly associated with pre-Medicare eligible individuals’ attitude toward Medicare Part D and this outcome was perceived significantly beneficial for them. (2) “my spouse/significant other” (a=1.54, p<0.0001) and “my parents” (a=0.42, p=0.03) were perceived to approve of Pre-Medicare eligible individuals’ enrollment in Medicare Part D; however, their motivations to comply with their opinions were not significant; (3) Pre-Medicare eligible individuals believed that “mailing materials about drug plans” (a=0.4, p=0.0042) and “consulting with my pharmacy” (a=0.5, p=0.0056) would make is easier for them to enroll in Medicare Part D. Structural equation modeling methods (confirmatory factor analysis and path analysis) were applied to investigate associations between factors (attitudes, subjective norms, and perceived behavioral controls) analyses and pre-Medicare eligible individuals’ enrollment intentions. Results showed that (1) attitude (r=0.39 p<0.001) and subjective norm (r=0.44 p<0.001) were significantly associated with pre-Medicare eligible individuals’ enrollment intentions in Medicare Part D; (2) subjective norm was the stronger predictor (r=0.49) than attitudes (r=0.35) of enrollment intentions in Medicare Part D for male pre-Medicare eligible individuals. However, the difference was not obvious (r attitude-intention=0.42 vs. r subjective norm-intention=0.40) for female individuals; (3) the TPB model had a reasonable good fit of the data to predict Medicare Part D enrollment intentions (R2= 0.616). This study showed that a more favorable evaluation of the Medicare Part D program, and a stronger perception of relevant others’ beliefs regarding enrolling in Medicare Part D drug plans could result in a stronger enrollment intentions of pre- Medicare eligible individuals. This study took the initial step to understand the decisionmaking process surrounding the Medicare Part D program enrollment in those pre- Medicare eligible individuals. Based on an understanding of the decision-making process of the Medicare Part D enrollment, the impact of this study could be enhanced by proving social support for Medicare beneficiaries in enrolling in Medicare programs. However, there was considerable variability in the observed association between behavioral intentions and actual behaviors. Further research is needed to explore the stability between Medicare Part D enrollment intentions of pre-Medicare eligible individuals and their actual enrollment behaviors. That will be more meaningful.Item Pre-Medicare Eligible Individuals’ Decision-Making In Medicare Part D: An Interview Study(University of Minnesota, College of Pharmacy, 2010) Jin, Tao; Cline, Richard R.; Hadsall, Ronald S.Objectives The objective of this study was to elicit salient beliefs among pre-Medicare eligible individuals regarding (1) the outcomes associated with enrolling in the Medicare Part D program; (2) those referents who might influence participants’ decisions about enrolling in the Part D program; and (3) the perceived barriers and facilitators facing those considering enrolling in the Part D program. Methods Focused interviews were used for collecting data. A sample of 10 persons between 62 and 64 years of age not otherwise enrolled in the Medicare program was recruited. Interviews were audio taped and field notes were taken concurrently. Audio recordings were reviewed to amend field notes until obtaining a thorough reflection of interviews. Field notes were analyzed to elicit a group of beliefs, which were coded into perceived outcomes, the relevant others who might influence Medicare Part D enrollment decisions and perceived facilitators and impediments. By extracting those most frequently mentioned beliefs, modal salient sets of behavioral beliefs, relevant referents, and control beliefs were identified. Results Analyses showed that (1) most pre-Medicare eligible believed that Medicare Part D could “provide drug coverage”, “save money on medications”, and “provide financial and health security in later life”. However, “monthly premiums”, “the formulary with limited drug coverage” and “the complexity of Medicare Part D” were perceived as major disadvantages; (2) immediate family members are most likely to influence pre-Medicare eligible’s decisions about Medicare Part D enrollment; and (3) internet and mailing educational brochures are considered to be most useful resources for Medicare Part D enrollment. Major barriers to enrollment included the complexity and inadequacy of insurance plan information. Conclusion There are multiple factors related to decision-making surrounding the Medicare Part D enrollment. These factors include the advantages and disadvantages of enrolling in Part D, facilitators and barriers to enrolling in Medicare Part D, and significant individuals and groups for pre-Medicare eligible individuals.
