Prescription Drug Costs for Dually Eligible People in a Medicaid Home- and Community-Based Services Program

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 7 2002
Victoria L. Phillips Dphil
This study examined the prescription drug costs of Medicare beneficiaries participating in a Medicaid home- and community-based services (HCBS) program and discussed possible implications of providing a prescription drug benefit under Medicare. The study examined Medicaid pharmaceutical claims data using two random samples (n = 766) of dually eligible Medicare beneficiaries in a HCBS program from four regions in Georgia. The average total monthly Medicaid prescription drug expenditure was determined. Annual prescription expenditures for this group averaged more than $1,500 per person. Prescription drugs intended for the treatment of cancer and circulatory disorders combined to account for 61% of total program drug expenditures. Multivariate analysis found that drug expenditures were higher for those who died during the observation period, the young-old, Caucasians, and those who self-selected into the program. Higher drug expenditures for the self-selected group, even after frailty adjustments, suggest the presence of adverse selection. Medicare prescription drug benefit proposals that rely on voluntary enrollment may also experience adverse selection from frail, low-income beneficiaries. [source]


Quantifying Components of Drug Expenditure Inflation: The British Columbia Seniors' Drug Benefit Plan

HEALTH SERVICES RESEARCH, Issue 5 2002
Steven G Morgan
Objective. To quantify the relative and absolute importance of different factors contributing to increases in per capita prescription drug costs for a population of Canadian seniors. Data Sources/Study Setting. Data consist of every prescription claim from 1985 to 1999 for the British Columbia Pharmacare Plan A, a tax-financed public drug plan covering all community-dwelling British Columbians aged 65 and older. Study Design. Changes in per capita prescription drug expenditures are attributed to changes to four components of expenditure inflation: (1) the pattern of exposure to drugs across therapeutic categories; (2) the mix of drugs used within therapeutic categories; (3) the rate of generic drug product selection; and (4) the prices of unchanged products. Data Collection/Extraction Methods. Data were extracted from administrative claims files housed at the UBC Centre for Health Services and Policy Research. Principal Findings. Changes in drug prices, the pattern of exposure to drugs across therapeutic categories, and the mix of drugs used within therapeutic categories all caused spending per capita to increase. Incentives for generic substitution and therapeutic reference pricing policies temporarily slowed the cost-increasing influence of changes in product selection by encouraging the use of generic drug products and/or cost-effective brand-name products within therapeutic categories. Conclusions. The results suggest that drug plans (and patients) would benefit from more concerted efforts to evaluate the relative cost-effectiveness of competing products within therapeutic categories of drugs.

Prevalence and cost of medication nonadherence in Parkinson's disease: Evidence from administrative claims data,

MOVEMENT DISORDERS, Issue 4 2010
Keith L. Davis MA
Abstract We estimated the prevalence of medication nonadherence in Parkinson's disease (PD) and the association between treatment nonadherence and healthcare costs. Insurance claims from over 30 US health plans were analyzed. Inclusion criteria were as follows: PD diagnosis, ,1 PD-related prescription between 1/1/1997 and 12/31/2004, continuous health plan enrollment for ,6 months before and ,12 months after first PD prescription. Adherence, all-cause healthcare utilization, and all-cause costs were evaluated over 12 months post-treatment initiation. Adherence was measured using the medication possession ratio (MPR), with MPR < 0.8 defining nonadherence. Among patients identified for inclusion (N = 3,119), 58% were male and mean age was 69 years. Mean MPR was 0.58 and 61% of patients were nonadherent. Unadjusted mean medical costs were significantly higher (P < 0.01) among nonadherers ($15,826) compared with adherers ($9,228), although nonadherers had lower prescription drug costs ($2,684 vs. $3,854; P < 0.05). After controlling for confounders in multivariable analyses, a large positive relationship between nonadherence and both medical and total healthcare costs remained (+$3,451, P < 0.0001 and +$2,383, P = 0.0053, respectively). Medication adherence in PD is suboptimal and nonadherence may be associated with increased healthcare costs despite offsets from reduced drug intake. Efforts to promote medication adherence in PD may lead to cost savings for managed care systems. © 2010 Movement Disorder Society [source]
