Increases in Medicare prescription drug plan costs attributable to psychotropic medications

Demographic and practice characteristics of Medicaid-participating dentists

OBJECTIVES

The challenges entailed in dental Medicaid programs are well documented. To increase our understanding of Medicaid participation, we surveyed Florida dentists to determine the demographic and practice characteristics of Medicaid-participating dentists.

METHODS

Our target population was practicing Florida dentists who treat children, including those who do not currently accept Medicaid as well as those who do. The final sample (n = 882) included (1) pediatric dentists and (2) general dentists who self-reported that they treat children. Participants completed a survey concerning their Medicaid participation. Analyses included survey-sample weighted chi-square tests and multivariable logistic regression.

RESULTS

More than two-thirds of the sample dentists are not participating in Medicaid and will not consider doing so. Key findings are that Black dentists across the state and Hispanics in South Florida are more likely to participate in Medicaid than other groups of Florida dentists. Pediatric dentists are more likely to be Medicaid participants than general dentists, but nearly one-fifth of the pediatric dentists might quit participation. Non-Medicaid providers are more likely to report not being busy enough in their practice than Medicaid providers.

CONCLUSIONS

If we are to address the shortage of Medicaid dental providers, increasing our understanding of how to capture the excess capacity among general dentists (the reported lack of busyness) in a way acceptable to dentists and to the State of Florida is an important first step. In addition, dental schools should consider implementing a track dedicated to training students for practice success within communities of highest dental need and to seek to increase the number of Black dental students.

Cost-related medication nonadherence in older patients with rheumatoid arthritis

OBJECTIVE

Economic access to costly medications including biologic agents can be challenging. Our objective was to examine whether patients with rheumatoid arthritis (RA) are at particular risk for cost-related medication nonadherence (CRN) and spending less on basic needs.

METHODS

We identified a nationally representative sample of older adults with RA (n = 1100) in the Medicare Current Beneficiary Survey (2004-2008) and compared them to older adults with other morbidities categorized by chronic disease count: 0 (n = 5898), 1-2 (n = 30,538), and ≥ 3 (n = 34,837). We compared annual rates of self-reported CRN (skipping or reducing medication doses or not obtaining prescriptions because of cost) as well as spending less on basic needs to afford medications and tested for differences using survey-weighted logistic regression analyses adjusted for demographic characteristics, health status, and prescription drug coverage.

RESULTS

In the RA sample, the unadjusted weighted prevalence of CRN ranged from 20.7% in 2004 to 18.4% in 2008 as compared to 18.5% and 11.9%, respectively, in patients with 3 or more non-RA conditions. In adjusted analyses, having RA was associated with a 3.5-fold increase in the risk of CRN (OR 3.52, 95% CI 2.63-4.71) and almost a 2.5-fold risk of spending less on basic needs (OR 2.41, 95% CI 1.78-3.25) as compared to those without a chronic condition.

CONCLUSION

Patients with RA experience a high prevalence of CRN and forgoing of basic needs, more than do older adults with multiple other chronic conditions. The situation did not improve during a period of policy change aimed at alleviating high drug costs.

The effect of depression and cognitive impairment on enrollment in Medicare Part D

OBJECTIVES

To examine concerns that vulnerable populations, such as depressed or cognitively impaired beneficiaries would have challenges accessing Part D coverage.

DESIGN

Logistic regression analysis was used to assess whether elderly Medicare beneficiaries with depression or cognitive impairment differentially planned to and actually signed up for Part D.

SETTING

2004 and 2006 data from the Health and Retirement Study (HRS) were used, including a subsample that completed the Prescription Drug Study (PDS) in 2005.

PARTICIPANTS

Nine thousand five hundred ninety-three HRS respondents and 3,567 PDS respondents.

MEASUREMENTS

The outcome variables of interest were planned and actual enrollment in Part D. The independent variables were depression and cognitive impairment status. The analyses were adjusted using clinical and demographic predictors including age, sex, race or ethnicity, educational attainment, net worth, marital status, health status, number of health conditions being treated with prescription medications, and presence of a caregiver.

RESULTS

Although having depression or cognitive impairment was associated with a higher likelihood of planning to and actually signing up for Part D in unadjusted analyses, in adjusted analyses, having depression or cognitive impairment was not significantly associated with whether Medicare beneficiaries planned to enroll in or actually enrolled in Part D.

CONCLUSION

Vulnerable Medicare beneficiaries with depression or cognitive impairment were able to access Part D benefits to the same extent as nonvulnerable beneficiaries. More research is needed to determine how well Part D meets the needs of these populations.
