Effect of Prescription Drug Coverage on Health of the Elderly

HEALTH SERVICES RESEARCH, Issue 5p1 2008

Objective. To estimate the effect of prescription drug insurance on health, as measured by self-reported poor health status, functional disability, and hospitalization among the elderly. Data. Analyses are based on a nationally representative sample of noninstitutionalized elderly (,65 years of age) from the Medicare Current Beneficiary Survey (MCBS) for years 1992,2000. Study Design. Estimates are obtained using multivariable regression models that control for observed characteristics and unmeasured person-specific effects (i.e., fixed effects). Principal Findings. In general, prescription drug insurance was not associated with significant changes in self-reported health, functional disability, and hospitalization. The lone exception was for prescription drug coverage obtained through a Medicare HMO. In this case, prescription drug insurance decreased functional disability slightly. Among those elderly with chronic illness and older (71 years or more) elderly, prescription drug insurance was associated with slightly improved functional disability. Conclusions. Findings suggest that prescription drug coverage had little effect on health or hospitalization for the general population of elderly, but may have some health benefits for chronically ill or older elderly.

The Effect of Transitioning to Medicare Part D Drug Coverage in Seniors Dually Eligible for Medicare and Medicaid

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 12 2008
William H. Shrank MD
OBJECTIVES: To evaluate medication use, out-of-pocket spending, and medication switching during the transition period for patients dually eligible for Medicaid and Medicare (dual eligibles). DESIGN: Time-trend analysis, using segmented linear regression. SETTING: Patient-level pharmacy dispensing data from January 2005 to December 2006 from a large pharmacy chain with stores in 34 states. PARTICIPANTS: Dual eligibles aged 65 and older. MEASUREMENTS: Changes in utilization, patient copayments, and medication switching were analyzed using interrupted time trend analyses. Utilization and spending were evaluated for five study drugs: clopidogrel, proton pump inhibitors (PPIs), warfarin, and statins (essential drugs covered by Part D plans) and benzodiazepines (not covered through Part D but potentially covered through Medicaid). RESULTS: Drug use for 13,032 dual eligibles was evaluated. There was no significant effect of the transition to Medicare Part D on use of all study drugs, including the uncovered benzodiazepines. Cumulative reductions were seen in copayments for all covered drugs after implementation of Part D, ranging from 25% annually for PPIs to 53% for warfarin, but there was a larger increase in copayments, 91% annually, for benzodiazepines after the transition. The rate of switching medications was 3.0 times as great for the PPIs after implementation of Part D than before implementation, but there was no significant change in the other study drug classes. CONCLUSION: These findings in a single, large pharmacy chain indicate that the transition plan for dual eligibles led to less medication discontinuation and switching than many had expected. The substantially greater cost sharing for benzodiazepines highlights the importance of implementing a thoughtful transition plan when executing such a national policy. [source]


Dynamic versus static models in cost-effectiveness analyses of anti-viral drug therapy to mitigate an influenza pandemic

HEALTH ECONOMICS, Issue 5 2010
Anna K. Lugnér
Abstract Conventional (static) models used in health economics implicitly assume that the probability of disease exposure is constant over time and unaffected by interventions. For transmissible infectious diseases this is not realistic and another class of models is required, so-called dynamic models. This study aims to examine the differences between one dynamic and one static model, estimating the effects of therapeutic treatment with antiviral (AV) drugs during an influenza pandemic in the Netherlands. Specifically, we focus on the sensitivity of the cost-effectiveness ratios to model choice, to the assumed drug coverage, and to the value of several epidemiological factors. Therapeutic use of AV-drugs is cost-effective compared with non-intervention, irrespective of which model approach is chosen. The findings further show that: (1) the cost-effectiveness ratio according to the static model is insensitive to the size of a pandemic, whereas the ratio according to the dynamic model increases with the size of a pandemic; (2) according to the dynamic model, the cost per infection and the life-years gained per treatment are not constant but depend on the proportion of cases that are treated; and (3) the age-specific clinical attack rates affect the sensitivity of cost-effectiveness ratio to model choice.

The Effect of Three-Tier Formulary Adoption on Medication Continuation and Spending among Elderly Retirees

HEALTH SERVICES RESEARCH, Issue 5 2007
Haiden A. Huskamp
Objective. To assess the effect of three-tier formulary adoption on medication continuation and spending among elderly members of retiree health plans. Data Sources. Pharmacy claims and enrollment data on elderly members of four retiree plans that adopted a three-tier formulary over the period July 1999 through December 2002 and two comparison plans that maintained a two-tier formulary during this period. Study Design. We used a quasi-experimental design to compare the experience of enrollees in intervention and comparison plans. We used propensity score methods to match intervention and comparison users of each drug class and plan. We estimated repeated measures regression models for each class/plan combination for medication continuation and monthly plan, enrollee, and total spending. We estimated logit models of the probability of nonpersistent use, medication discontinuation, and medication changes. Data Collection/Extraction Methods. We used pharmacy claims to create person-level drug utilization and spending files for the year before and year after three-tier adoption. Principal Findings. Three-tier formulary adoption resulted in shifting of costs from plan to enrollee, with relatively small effects on medication continuation. Although implementation had little effect on continuation on average, a small minority of patients were more likely to have gaps in use and discontinue use relative to comparison patients. Conclusions. Moderate cost sharing increases from three-tier formulary adoption had little effect on medication continuation among elderly enrolled in retiree health plans with relatively generous drug coverage.

Insurance Coverage of Prescription Drugs and the Rural Elderly

THE JOURNAL OF RURAL HEALTH, Issue 1 2004
Curt Mueller PhD
ABSTRACT: Context: Rural impacts of a Medicare drug benefit will ultimately depend on the number of elderly who are currently without drug coverage, new demand by those currently without coverage, the nature of the new benefit relative to current benefits, and benefit design. Purpose: To enhance understanding of drug coverage among rural elderly Medicare beneficiaries and their expenditures for pharmaceuticals. Methods: Estimates of the extent of coverage, expenditures, and sources of drugs were obtained using data are from the 1997 Medicare Current Beneficiary Survey and the Pharmacy Verification and Household Components of the 1996 Medical Expenditure Panel Survey. Findings: Three-quarters of the urban elderly had some type of drug coverage in 1997 versus 59% of the elderly in rural areas. Urban residents were more likely to have obtained their drug coverage from an employersponsored supplemental plan, and rural residents were more likely to have self-purchased Medigap drug coverage. Expenditures and use of drugs by Medicare beneficiaries are greater for those with than without coverage, and differences are invariant with respect to geographic location. Coverage under self-purchased supplemental plans appears less generous than under employer-sponsored plans in both rural and urban areas. Rural and urban elderly are more than twice as likely to receive at least 1 prescribed medication through the mail than the general population. Conclusion: A well-designed Medicare drug benefit would be especially beneficial to the rural elderly because relatively more rural elderly currently lack coverage or have less generous coverage than urban beneficiaries. Mail-order distribution may help contain future program expenditures. [source]
