Elderly Patients' Knowledge of Drug Benefit Caps and Communication with Providers About Exceeding Caps

OBJECTIVES: Many elderly persons have drug benefits with coverage gaps, such as in Medicare Part D. Because beneficiaries who have such gaps must pay all drug costs, an accurate knowledge of gap thresholds and communication with providers about exceeding caps is important for elderly persons to manage out-of-pocket drug costs.
DESIGN: Cross-sectional survey.
SETTING: Health plan.
PARTICIPANTS: One thousand three hundred eight health plan members aged 65 and older. The study was a 2002 cross-sectional survey of elderly persons with capped drug benefits in a managed care plan in one state. Participants were sampled so that half reached coverage caps and half did not.
METHODS: Participants reported cap levels, communication with providers about exceeding caps, and decreased medication use due to cost.
RESULTS: Of the 1,308 participants (65.4% response rate), 68.6% did not know their correct cap level. Rates were similar in those who exceeded caps (66.2%), reported difficulty paying for medications (63.9%), or decreased medication use (66%). For participants who exceeded caps, 59.1% did not know beforehand that they were close to exceeding caps and 50.2% did not tell providers afterward. In multivariate analyses accounting for demographics and health, the oldest participants (≥85 vs 65–74) were at greater risk for not knowing cap levels (odds ratio (OR)=2.0, 95% confidence interval (CI)=1.2–3.4) and not telling providers about exceeding caps (OR=2.2, 95% CI=1.1–4.5).
CONCLUSIONS: Elderly patients often did not know correct cap levels and did not tell providers about exceeding caps. Providers, plans, and policymakers should actively assess and improve Medicare beneficiaries' knowledge of Part D coverage gaps.     

Effect of Influenza Vaccination of Nursing Home Staff on Mortality of Residents: A Cluster-Randomized Trial

OBJECTIVES: To evaluate the effect of staff influenza vaccination on all-cause mortality in nursing home residents.
DESIGN: Pair-matched cluster-randomized trial.
SETTING: Forty nursing homes matched for size, staff vaccination coverage during the previous season, and resident disability index.
PARTICIPANTS: All persons aged 60 and older residing in the nursing homes.
INTERVENTION: Influenza vaccine was administered to volunteer staff after a face-to-face interview. No intervention took place in control nursing homes.
MEASUREMENTS: The primary endpoint was total mortality rate in residents from 2 weeks before to 2 weeks after the influenza epidemic in the community. Secondary endpoints were rates of hospitalization and influenza-like illness (ILI) in residents and sick leave from work in staff.
RESULTS: Staff influenza vaccination rates were 69.9% in the vaccination arm versus 31.8% in the control arm. Primary unadjusted analysis did not show significantly lower mortality in residents in the vaccination arm (odds ratio=0.86, P =.08), although multivariate-adjusted analysis showed 20% lower mortality ( P =.02), and a strong correlation was observed between staff vaccination coverage and all-cause mortality in residents (correlation coefficient=−0.42, P =.007). In the vaccination arm, significantly lower resident hospitalization rates were not observed, but ILI in residents was 31% lower ( P =.007), and sick leave from work in staff was 42% lower ( P =.03).
CONCLUSION: These results support influenza vaccination of staff caring for institutionalized elderly people.     

Medicare Part D's effect on the under- and overuse of medications: a systematic review

OBJECTIVES: To evaluate the literature regarding the effect of Medicare Part D on the under‐ and overuse of specific medications and corresponding health outcomes. DESIGN: Systematic review. SETTING: Medline search of the peer‐reviewed literature from January 1, 2006, to October 8, 2010. PARTICIPANTS: Medicare beneficiaries who obtained drug insurance from the Part D program. MEASUREMENTS: The review evaluated changes in the use of specific drugs or drug classes after implementation of Part D, as described in original, peer‐reviewed articles. RESULTS: Nineteen articles met inclusion criteria. Part D's implementation was associated with greater use of essential medications such as clopidogrel and statins, especially in beneficiaries who had been previously uninsured, but increases in inappropriate antibiotic use for the treatment of acute respiratory tract infections and increases in claims for the often overused proton pump inhibitor drug class were also observed. In the Part D transition period, dually eligible beneficiaries' drug use remained largely unchanged. When beneficiary cost sharing increased in the coverage gap, use of essential and overused medications declined. CONCLUSION: Increasing drug coverage led to greater use of underused essential medications and inappropriate, or overused, medications under Medicare Part D. Despite efforts to have it do so, the Part D benefit did not sufficiently discriminate between essential and nonessential medication use.
