Costs and Cost-Effectiveness of the Patient-Centered HIV Care Model: A Collaboration Between Community-Based Pharmacists and Primary Medical Providers.

BACKGROUND: The patient-centered HIV care model (PCHCM) is an evidence-informed structural intervention that integrates community-based pharmacists with primary medical providers to improve rates of HIV viral suppression. This report assesses the costs and cost-effectiveness of the PCHCM. SETTING: Patient-centered HIV care model. METHODS: Three project sites, each composed of a medical clinic and 1 or 2 community-based HIV-specialized pharmacies, were included in the analyses. PCHCM required patient data sharing between medical providers and pharmacists and collaborative therapy-related decision making. Intervention effectiveness was measured as the incremental number of patients virally suppressed (HIV RNA <200 copies/mL at the last test in a 12-month measurement period). Microcosting direct measurement methods were used to estimate intervention costs. The cost per patient, cost per patient visit, and incremental cost per patient virally suppressed were calculated from the health care providers' perspective. Additionally, the number of HIV transmissions averted, lifetime HIV treatment cost saved, quality-adjusted life years (QALYs) saved, and cost per QALY saved were calculated from the societal perspective, using standard methods and reported values from the published literature. RESULTS: Overall, the PCHCM annual intervention cost for the 3 project sites was $226,741. The average cost per patient, cost per patient visit, and incremental cost per patient virally suppressed were $813, $48, and $5,039, respectively. The intervention averted 2.75 HIV transmissions and saved 12.22 QALYs and nearly $1.28 million in lifetime HIV treatment costs. The intervention was cost saving overall and at each project site. CONCLUSIONS: The PCHCM can be delivered at a relatively low cost and is a cost-saving intervention to assist patients in achieving viral suppression and preventing HIV transmission.

Work System and Process Designs for Community Pharmacy-Medical Clinic Partnerships to Improve Retention in Care, Antiretroviral Adherence, and Viral Suppression in Persons with HIV.

The objective of this project was to collect and analyze information about work systems and processes that community pharmacy-medical clinic partnerships used for implementing the Patient-Centered HIV Care Model (PCHCM). Paired collaborations of 10 Walgreens community pharmacies and 10 medical clinics were formed in 10 cities located throughout the United States that had relatively high HIV prevalence rates and existing Walgreens HIV Centers of Excellence. Patient service provision data and most significant change stories were collected from key informants at each of the clinic and pharmacy sites over an 8 week period in 2016 and through in-depth phone interviews. Written notes were reviewed by two authors (J.C.S. and O.W.G.) and analyzed using the most significant change technique. The findings showed that half of the partnerships (n = 5) were unable to fully engage in service implementation due to external factors or severe staff turnover during the project period. The other half of the partnerships (n = 5) were able to engage in service implementation, with the most impactful changes being related to strong patient care systems, having a point person at the clinic who served as a connector between sites, and having pharmacists integrated fully into the health care team.

Improving Medication Adherence and Health Care Outcomes in a Commercial Population through a Community Pharmacy.

The aim was to evaluate the impact of a multifaceted set of medication management interventions offered by a community pharmacy on adherence, health care utilization, and costs within a commercial population. Patients initiating therapy within 16 drug classes from February 7, 2013, to October 6, 2013, were offered various adherence interventions by Walgreens pharmacy. Patients were linked deterministically to IMS medical and prescription databases for 6-month pre- and post-index data analysis. Walgreens patients (intervention) were matched to patients using other pharmacies (control) on drug class, index date, baseline demographics, clinical factors, utilization, and costs. Outcomes were evaluated at the intent-to-treat level using post-index differences and generalized estimating equations (GEE) regression model. Paired t tests (continuous variables) and McNemar's test (dichotomous variables) were used to determine the significance of estimated model coefficients at α = 0.05. The groups (n = 72,410 each) had similar age (47.1 vs. 45.7 years), sex (41.2% vs. 40.2% male), and disease burden (0.52 vs. 0.40 mean Charlson comorbidity index). In the 6-month post-index period, the intervention group had 3.0% greater medication adherence, 1.8% fewer hospital admissions, 2.7% fewer emergency room (ER) visits, and 0.53 fewer mean outpatient visits compared to the control group (all P < 0.0001). The intervention group incurred significantly lower GEE-adjusted pharmacy costs (-$92), outpatient costs (-$120), ER costs (-$38), and total health care costs (-$226.07) (all P < 0.0001), and higher inpatient costs ($86, P < 0.004) per patient. A multifaceted set of medication management interventions offered by a community pharmacy were associated with patients in a commercial population having significantly higher medication adherence and lower health care utilization and costs.

Wellness program satisfaction, sustained coaching participation, and achievement of health goals.

OBJECTIVE: To examine factors associated with program satisfaction for participants of a comprehensive workplace wellness program. METHODS: Data from satisfaction surveys completed by 17,896 program participants were used to examine the association between demographics, program satisfaction, sustained coaching participation, and odds of meeting health goals. Inferential statistical analysis was used to assess average satisfaction rates, and generalized estimating equations were used to estimate the effect of program satisfaction on sustained coaching participation and odds of meeting health goals while controlling for potential confounds. RESULTS: Statistically significant positive associations were found between participant satisfaction and sustained coaching participation, and factors associated with both were being older, being female, having greater program maturity, having higher incentive amounts, and having participation through telephonic coaching modality. CONCLUSIONS: Wellness program participant satisfaction is positively associated with sustained coaching participation and achievement of health goals.

Factors associated with long-term weight loss and weight maintenance: analysis of a comprehensive workplace wellness program.

OBJECTIVE: To examine factors associated with long-term weight loss and maintenance for participants of a comprehensive workplace wellness program. METHODS: Data came from Health Risk Assessments completed by 89,746 overweight and obese persons between 2005 and 2010 to examine the association between demographics, improved nutrition, improved exercise and reduced stress and odds of weight loss and weight maintenance, as well as changes in bodyweight at 1 year follow-up. Generalized estimating equations were used to estimate coefficients of interest while controlling for confounds. RESULTS: Factors significantly associated with increased odds and amount of weight loss were male gender, older age, reduced psychosocial stress, improved nutrition, and increased exercise when combined with improved nutrition. CONCLUSIONS: Comprehensive workplace wellness programs that address weight management through an integrated stress management approach can be effective in addressing the obesity epidemic.
