Doctor–Patient Communication, Health-Related Beliefs, and Adherence in Glaucoma : Results from the Glaucoma Adherence and Persistency Study

OBJECTIVE To use multiple data sources to determine drivers of patient adherence to topical ocular hypotensive therapy. DESIGN Retrospective database and chart reviews in combination with prospective patient surveys. Diverse medical environments where insured patients in the research database seek care. PARTICIPANTS Three hundred patients with a new claim diagnosis for open-angle glaucoma who initially were prescribed one of three prostaglandins and 103 physicians participating in the same medical plans. METHODS A structured interview addressing self-reported adherence, experiences with medication, communication with the physician, and health-related beliefs associated with adherence behavior was administered to surveyed patients. Phone interviews were conducted with participating ophthalmologists. MAIN OUTCOME MEASURE Of adherence, medication possession ratio. RESULTS Eight variables were associated independently with a lower medication possession ratio: (1) hearing all of what you know about glaucoma from your doctor (compared with some or nothing); (2) not believing that reduced vision is a risk of not taking medication as recommended; (3) having a problem paying for medications; (4) difficulty while traveling or away from home; (5) not acknowledging stinging and burning; (6) being nonwhite; (7) receiving samples; and (8) not receiving a phone call visit reminder. The multivariate model explained 21% of the variance. CONCLUSIONS These findings indicate that doctor-patient communications and health-related beliefs of patients contribute to patient adherence. Patient learning styles that are associated with less concern about the future effects of glaucoma and the risks of not taking medications are associated with lower adherence. Specifically, knowledge about potential vision loss from glaucoma is a critical element that tends to be missed by more passive doctor-dependent patients who tend to be poorly adherent. These findings suggest that educational efforts in the office may improve patient adherence to medical therapies.

Impact of donepezil treatment for Alzheimer's disease on caregiver time

SUMMARY Objective: To assess the impact of donepezil treatment compared with placebo on caregiver time spent assisting patients with Alzheimers disease (AD). Research design and methods: Patient and caregiver data were collected as part of a 1-year, prospective, double-blind, randomized, placebo-controlled trial. The Resource Utilization in Dementia (RUD) questionnaire was used to record caregiver time at study baseline and at Weeks 12, 24, 36, and 52. This analysis focuses solely on those caregivers who were actively (> 0 h/day reported on the RUD) providing care at study baseline. Main outcome measures: The change in time relative to baseline that caregivers spent assisting patients over the course of the study. Results: The active caregiver population was composed of 96 caregivers of donepezil-treated patients and 94 caregivers of patients receiving placebo. Over the course of the 1-year study, and as the condition of the AD patients deteriorated, it was expected that caregiver time would increase. As expected, after 52 weeks, caregivers of placebo patients were providing almost 2 h each day (106.8 min) more care than they had done at study baseline. For those caregivers of donepezil-treated patients, although they were spending more time caring than they had done at study baseline, their time burden had only increased by 42.6 min more each day. This difference in caring time between the 2 groups, relative to baseline at Week 52, was 1.1 h (64.2 min) each day, and was significant ( p = 0.03). Conclusion: Caregiver time devoted to helping an AD patient typically increases with the severity of the disease. By helping the patient maintain his/her ability to perform activities of daily living for longer, treatment with donepezil is not only beneficial to the patient, but also has positive time-burden implications for the caregiver.

The Impact of Menopausal Symptoms on Quality of Life, Productivity, and Economic Outcomes

BACKGROUND The aim of this study was to investigate the impact of menopausal symptoms and menopausal symptom severity on health-related quality of life (HRQoL), work impairment, healthcare utilization, and costs. METHODS Data from the 2005 United States National Health and Wellness Survey were used, with only women 40-64 years without a history of cancer included in the analyses (N=8,811). Women who reported experiencing menopausal symptoms (n=4,116) were compared with women not experiencing menopausal symptoms (n=4,695) on HRQoL, work impairment, and healthcare utilization using regression modeling (and controlling for demographics and health characteristic differences). Additionally, individual menopausal symptoms were used as predictors of outcomes in a separate set of regression models. RESULTS The mean age of women in the analysis was 49.8 years (standard deviation,±5.9). Women experiencing menopausal symptoms reported significantly lower levels of HRQoL and significantly higher work impairment, and healthcare utilization than women without menopausal symptoms. Depression, anxiety, and joint stiffness were symptoms with the strongest associations with health outcomes. CONCLUSIONS Menopausal symptoms can be a significant humanistic and economic burden on women in middle age.

The Clinical and Economic Burden of Newly Diagnosed Alzheimer’s Disease in a Medicare Advantage Population

Background/Rationale: Alzheimer’s disease (AD) represents a serious public health issue affecting approximately 5.4 million individuals in the United States and is projected to affect up to 16 million by 2050. This study examined health care resource utilization (HCRU), costs, and comorbidity burden immediately preceding new diagnosis of AD and 2 years after diagnosis. Methods: This study utilized a claims-based, retrospective cohort design. Medicare Advantage members newly diagnosed with AD (n = 3374) were compared to matched non-AD controls (n = 6748). All patients with AD were required to have 12 months of continuous enrollment prior to AD diagnosis (International Classification of Diseases, Clinical Modification [ICD-9] 331.0), during which time no diagnosis of AD, a related dementia, or an AD medication was observed. Non-AD controls demonstrated no diagnosis of AD, a related dementia, or a prescription claim for an AD medication treatment during their health plan enrollment. Medical and pharmacy claims data were used to measure HCRU, costs, and comorbidity burden over a period of 36 months (12 months pre-diagnosis and 24 months post-diagnosis). Results: The HCRU and costs were greater for AD members during the year prior to diagnosis and during postdiagnosis years 1 and 2 compared to controls. The AD members also displayed greater comorbidity than their non-AD counterparts during postdiagnosis years 1 and 2, as measured by 2 different comorbidity indices. Conclusions: Members newly diagnosed with AD demonstrated greater HCRU, health care costs, and comorbidity burden compared to matched non-AD controls.

Cost-Effectiveness Model for Neovascular Age-Related Macular Degeneration: Comparing Early and Late Treatment with Pegaptanib Sodium Based on Visual Acuity

OBJECTIVE To compare the cost-effectiveness of pegaptanib and usual care within three distinct cohorts of subfoveal neovascular age-related macular degeneration (NV-AMD) patients, that is, those with early, moderate, and late disease, using a comprehensive economic model. METHODS A Markov framework was used to model lifetime movement of a subfoveal NV-AMD cohort through health states based on visual acuity. The model takes a US payer perspective of patients over the age of 65 years. Clinical efficacy was based on published results for the 0.3 mg pegaptanib and usual care groups. Expert interviews were conducted to determine adverse event treatment patterns and vision rehabilitation resource use. Incidence and costs of comorbidities such as depression and fractures associated with the effects of declining visual acuity were based on our previously published analysis of Medicare data. Transition probabilities were derived from published clinical trial data for each 3-month cycle. Utilities were derived from published sources. Three runs of the model were conducted with cohorts of newly diagnosed patients. Patients were classified as having early, moderate, or late NV-AMD defined as visual acuity in the better-seeing eye of 20/40 to more than 20/80, 20/80 to more than 20/200, and 20/200 to more than 20/400, respectively. Costs and outcomes were discounted 3.0% per annum. RESULTS Incremental costs per vision-year gained and per quality-adjusted life-year (QALY) gained for early NV-AMD patients were approximately one-third those of patients with late disease (

Sensitivity analysis showed that base-case incremental costs per QALY gained for pegaptanib versus usual care were relatively robust. CONCLUSIONS For patients with subfoveal NV-AMD, treatment with pegaptanib should be started as early as possible to maximize the clinical and economic benefits.
