Evaluation of Pharmacists' Work in a Physician-Pharmacist Collaborative Model for the Management of Hypertension.

ABSTRACT: Physician-pharmacist collaborative models have been shown to improve the care of patients with numerous chronic medical conditions. Team-based health care using integrated clinical pharmacists provides one opportunity to improve quality in health care systems that use population-based financing. In November 2015, the Centers for Medicare and Medicaid Services (CMS) requested that the relative value of pharmacists' work in team-based care needs to be established. Thus the objective of this study was to describe the components of pharmacists' work in the management of hypertension with a physician-pharmacist collaborative model.Descriptive analysis of the components of pharmacists' work in the Collaboration Among Pharmacists and Physicians to Improve Outcomes Now (CAPTION) study, a prospective, cluster randomized trial.This analysis was intended to provide policymakers with data and information, using the CAPTION study model, on the time and intensity of pharmacists' work to understand pharmacists' relative value contributions in the context of CMS financing and population management aims. The CAPTION trial was conducted in 32 community-based medical offices in 15 U.S. states and included 390 patients with multiple cardiovascular risk factors. Blood pressure was measured by trained study coordinators in each office, and patients were included in the study if they had uncontrolled blood pressure. Included patients were randomized to a 9-month intervention, a 24-month intervention, or usual care. The goal of the pharmacist intervention was to improve blood pressure control and resolve drug therapy problems impeding progress toward blood pressure goals. This intervention included medical record review, a structured assessment with the patient, collaboration to achieve goals of therapy, and patient follow-up. The two intervention arms (9 and 24 mo) were identical the first 9 months, and that time frame is the focus of this workload evaluation. Pharmacists completed study encounter forms for every patient encounter and estimated time spent in pre-visit, face-to-face care, and post-visit activities. Among the 390 patients, there were 2811 encounters with pharmacists that involved 3.44 hours/patient for face-to-face care visits plus 1.55 hours/patient for pre-visit and post-visit work. Intensity of work was reflected in interventions to resolve drug therapy problems with patients (43% of encounters) and with physicians (1169 recommendations, of which physicians accepted 1153 [98.6%]), resulting in improvement of patients' blood pressure goals achieved (from 0% at baseline to 43% at 9 months based on the primary study end point).Pharmacists provided extensive interventions to patients with hypertension. This analysis provides a framework for health systems, provider groups, and payers to measure pharmacists' work in value-based financing and population management.

Project description:Background: Pirfenidone is an anti-fibrotic agent used to treat patients with idiopathic pulmonary fibrosis (IPF). Managing adverse drug events and ensuring compliance with pirfenidone treatment for a prolonged period are important to reduce the rate of disease progression. To maximize the benefits of pirfenidone treatment, we established and evaluated an ambulatory care pharmacy practice, a model of pharmacist-physician collaborative management, for patients receiving pirfenidone. Methods: We conducted a retrospective chart review of 76 consecutive patients treated with pirfenidone in the Kobe City Medical Center General Hospital, Japan, between January 2012 and January 2019. The first group (61 patients) received pirfenidone treatment as conventional management, whereas the second group (15 patients) started pirfenidone based on collaborative pharmacist-physician management. The drug discontinuation rate and time to drug discontinuation were compared between the groups. To analyze factors associated with pirfenidone discontinuation, we used a multivariate Cox regression analysis to evaluate the baseline characteristics of patients, including those receiving the collaborative management. Clinical outcomes were compared using a propensity score matched analysis. Results: In the collaborative management group, pharmacists made 56 suggestions, including suggestions for supportive care (51 suggestions), to the physicians. Among these suggestions, 52 were accepted by the physicians. The discontinuation rates at 3 [6.7% (1/15) vs. 26.2% (16/61)] and 6 [9.1% (1/11) vs. 36.1% (22/61)] months were lower in the collaborative management group than in the conventional management group. Multivariate analysis revealed that collaborative management [hazard ratio (HR) 0.34, 95% CI 0.08-0.96, p = 0.041] and predicted baseline forced vital capacity <60% (HR 2.13, 95% CI 1.17-3.85, p = 0.015) were significantly associated with pirfenidone discontinuation. The time to drug discontinuation was also significantly longer in the collaborative management group than in the conventional management group (p = 0.034, log-rank test). Propensity score matched analysis confirmed a significant correlation between collaborative management and drug discontinuation time (HR 0.20, 95% CI 0.03-0.84, p = 0.027). Conclusions: We established an ambulatory care pharmacy practice for out-patients with IPF receiving pirfenidone. The results suggest that collaborative management may help prevent pirfenidone discontinuation compared with conventional management.

Project description:Study objectiveTo assess blood pressure control after discontinuation of a physician-pharmacist collaborative intervention.DesignComparative analysis of data of the patients who received the intervention versus a control group from a prospective, cluster-randomized, 9-month efficacy trial and the same patients' data 18 and 27 months after completion of the trial, abstracted from their medical records.SettingFive primary care medical offices operated by a university health system.PatientsOne hundred four patients with hypertension; 65 were in the intervention group, and 39 were in the control group.Measurements and main resultsIn the prospective study, patients were randomized to receive a physician-pharmacist collaborative intervention to improve blood pressure control or to the control group. Systolic and diastolic blood pressures were measured by a research nurse at baseline and at the end of the study (9 mo later). In the current study, data were abstracted for blood pressure and blood pressure control at 18 and 27 months (9 and 18 mo, respectively, after discontinuation of the study). At baseline, mean +/- SD systolic blood pressure was 152.5 +/- 9.5 and 150.1 +/- 9.6 mm Hg in the intervention and control groups, respectively (p=0.22). At 9 months, systolic blood pressure decreased to 124.5 +/- 10.7 and 132.0 +/- 15.1 mm Hg (p=0.0038 between groups), and blood pressure was controlled in 78.5% and 48.7% (p=0.0017) of patients in the intervention and control groups, respectively. By 18 months, systolic blood pressure had deteriorated to 131.0 +/- 12.2 and 143.3 +/- 17.5 mm Hg (p<0.001), and blood pressure control rates decreased to 53.9% and 30.8% (p=0.02). By 27 months, systolic blood pressure was 131.3 +/- 13.0 and 141.2 +/- 15.8 mm Hg (p=0.0008), and blood pressure control was 55.4% and 35.9% (p=0.05).ConclusionA sustained positive effect on blood pressure control was noted up to 18 months after discontinuation of a physician-pharmacist collaborative intervention, when compared with a control group. Blood pressure control did deteriorate at a similar rate in both the intervention and control groups, but the percentage of patients with controlled blood pressure remained significantly higher in the intervention group. These results suggest that continued interventions by pharmacists may be necessary to maintain high rates of blood pressure control, especially in those patients whose blood pressure begins to increase.

Project description:Background:Pharmacist-managed (team-based) care for hypertension with home blood pressure monitoring support interventions have been widely studied and shown to be effective in improving rates of hypertension control and lowering blood pressure; however, few studies have evaluated the economic considerations related to bringing these programs into usual practice. Objective:To analyze the economic outcomes of the Blood Pressure Telemonitoring and Pharmacist Management on Blood Pressure (Hyperlink) study, a cluster randomized controlled trial which used home blood pressure telemonitoring and pharmacist case management to achieve better blood pressure control in patients with uncontrolled hypertension. Methods:A prospective analysis compared differences in medical costs and encounters in the Hyperlink telemonitoring intervention and usual care groups in the 12 months pre- and post-enrollment using medical and pharmacy insurance claims from a health care sector perspective. Generalized estimating equation models were used to estimate differences between groups over time. These results, combined with previously published prospective study results on intervention costs and blood pressure outcomes, were used to estimate cost-effectiveness measures for blood pressure control and reduction. Findings:Total medical costs in the intervention group were lower compared with the usual care group by an average of $281 per person, but this difference was not statistically significant. Clinic-based office visit, radiology, pharmacy, and hospital costs were also non-significantly lower in the intervention group. Statistically significant differences were found in lipid-related laboratory costs (higher) and in hypertension- (higher) and lipid-related (lower) pharmacy costs. Patterns in medical costs were similar for medical encounters. On average, the intervention cost $7337 per person achieving hypertension control and $139 or $265 per mm Hg reduction in systolic or diastolic blood pressure, respectively. Conclusions:Home blood pressure monitoring and pharmacist case management to improve hypertension care can be implemented without increasing, and potentially reducing, overall medical care costs.

Project description:Studies have demonstrated that physician/pharmacist collaboration can improve management of chronic conditions.The purpose of this study was to determine whether a correlation exists between existing clinical pharmacy services within a practice-based research network (PBRN) and provider attitudes and beliefs regarding implementing a new pharmacy intervention based on the Theory of Planned Behavior (TPB).A validated survey was completed by one clinical pharmacist from each office. This instrument evaluated the current clinical pharmacy services provided in the medical office. TPB instruments were developed that measured beliefs concerning implementation of a clinical pharmacy intervention for either blood pressure or asthma. The pharmacy services and TPB surveys were then administered to physicians and pharmacists in 32 primary care offices throughout the United States.Physicians returned 321 (35.9%) surveys, while pharmacists returned 40 (75.5%). The Cronbach's alpha coefficients generally ranged from 0.65 to 0.98. TPB subscale scores were lower in offices rated with lower pharmacy service scores, but these differences were not statistically significant. There was no correlation between clinical pharmacy service score and providers' TPB subscale scores. In both the hypertension and asthma groups, pharmacists scores were significantly higher than physicians' scores on the attitudes subscale in the multivariate analysis (P < 0.001 and P < 0.05, respectively).Pharmacists consistently scored higher than physicians on the TPB, indicating that they felt the hypertension or asthma intervention would be more straightforward for them to implement than did physicians. There was no significant correlation between clinical pharmacy service scores and attitudes toward implementing a future physician/pharmacist collaborative intervention using the TPB. Future studies should investigate the ability of the TPB instrument to predict implementation of a similar intervention in offices of physicians never exposed to clinical pharmacy services.
