Health literacy and health care spending and utilization in a consumer-driven health plan.

We examined health literacy and health care spending and utilization by linking responses of three health literacy questions to 2006 claims data of enrollees new to consumer-driven health plans (n = 4,130). Better health literacy on all four health literacy measures (three item responses and their sum) was associated with lower total health care spending, specifically, lower emergency department and inpatient admission spending (p < .05).

Behavioral healthcare services use in health savings accounts versus traditional health plans.

Background: Numerous studies have examined behavioral health services via employer-sponsored health insurance cost-sharing measures. Their results clearly indicate that health plan design matters a great deal with respect to behavioral health utilization. It is also clear that there remain a number of unresolved issues, particularly with respect to the effects of a switch from traditional plan designs to high deductible, consumer-driven policies.

Population pharmacokinetics of valproic acid concentrations in elderly nursing home residents.

The objective of this study was to identify factors that affect valproic acid (VPA) apparent clearance (CL/F) in elderly nursing home residents. Inclusion criteria included residency in a nursing home for at least 2 months, aged 65 years or older, a stable dosing regimen of VPA for at least 4 weeks, VPA concentration, and complete dosing information. CL/F was analyzed by a nonlinear mixed effects model.

Carbamazepine dose-concentration relationship in elderly nursing home residents.

Purpose: To describe the dose-concentration relationships of carbamazepine (CBZ) in elderly nursing home residents and the effect of sex, age, and type of co-medications.

Results: This is a cross-sectional study of elderly (> or = 65 years) nursing home residents across the United States (N=92). Data collection was from 1 June 1998 to 31 December 2000.

The validity of epilepsy or seizure documentation in nursing homes.

Recent studies have reported that epilepsy and seizures are common in nursing homes. Prevalence has been reported to range from 5 to 9% and antiepileptic drug (AED) use is even more common. Most of these studies have relied on various forms of nursing home records, but the validity of this source data, while assumed, has not been verified.

Effects of collaborative drug therapy management on patients' perceptions of care and health-related quality of life.

Background: It has been demonstrated that collaborative drug therapy management may result in enhanced medication adherence and improved clinical outcomes. It is not yet known whether CDTM is associated with patients' perceptions of care or self-reports of health-related quality of life.

Objectives: Examine the impact of collaborative drug therapy management (CDTM) on patients' perceptions of care and health-related quality of life in 15 ambulatory clinics (6 intervention, 9 comparison) in the Fairview system of Minneapolis-St Paul, Minn.

Demographic factors associated with dental utilization among community dwelling elderly in the United States, 1997.

Objectives: The purpose of this study was to characterize dental service utilization in 1997 by community dwelling Medicare beneficiaries.

Methods: The Medicare Current Beneficiary Survey, or MCBS, is a continuous annual series of nationally representative surveys of Medicare beneficiaries. Univariate comparisons were made between dependent variables (dental utilization and types of dental services) by each of the independent variables (age group, gender, race, income, education, population density, marital status and U.

Prevalence of appropriate and problematic antiepileptic combination therapy in older people in the nursing home.

Objectives: To determine the prevalence of mono- and poly-antiepileptic drug (AED) therapy in a cohort of nursing home (NH) residents and to describe specific AED combinations used, as well as demographic, clinical, and functional factors associated with poly-AED therapy and the most common AED combination.

Design: Retrospective, point prevalence study.

Setting: All NHs owned/managed by Beverly Enterprises.

Valproic acid doses, concentrations, and clearances in elderly nursing home residents.

VPA daily dose and total VPA concentrations for 146 elderly (> or =65 years) nursing home residents collected from June 1998 to December 2000 in homes located throughout the United States are presented. Average age was 78.5+/-8.

Phenytoin use in elderly nursing home residents.

Background: Phenytoin (PHT) dosing regimens are often determined based on experience in those aged <65 years rather than in those aged >or=65 years.

Objective: The goal of this study was to determine the impact of sex, age, receipt of concomitant inhibitors or inducers of PHT metabolism, and albumin levels on doses and total serum concentrations of PHT in elderly nursing home residents.

Methods: Consulting pharmacists to nursing homes located throughout the United States collected data from June 1998 to December 2000.

Antiepileptic drug use in nursing home admissions.

Although 1 of 10 nursing home residents is taking an antiepileptic drug (AED), no study to our knowledge has determined whether most residents are already receiving AED treatment when they are admitted or are given these drugs afterward. That differentiation was the focus of this study. The study group consisted of 10,318 residents, 65 years and older, admitted to 510 nursing homes located throughout the United States during the first quarter of 1999.
