BC Clinical impact of medication reviews with follow-up in cardiovascular older patients in primary care: A cluster-randomized controlled trial.

AIMS: Cardiovascular diseases (CVD) are the primary cause of death in Chile. Pharmacist-led medication review with follow-up (MRF) has improved CVD risk factors control in Europe and North America. However, their healthcare systems differ from Chile's, precluding generalizability. This trial aimed to determine the effect of MRF on CVD risk factor control among older patients with polypharmacy attending public primary care centres in Chile. METHODS: A cluster-randomized controlled trial was conducted in 24 centres. Patients older than 65 years with moderate-to-high CVD risk, five or more medications, hypertension, type 2 diabetes or dyslipidaemia, received MRF in addition to usual care or usual care alone for 12 months. Primary outcome measures were clinical goal achievement for hypertension, type 2 diabetes and dyslipidaemia, as well as medication adherence, medication number and CVD risk score. Adjusted generalized estimating equations were used, with odds ratios (ORs) for binary measures and mean differences for continuous measures. RESULTS: In total, 324 patients from 12 centres (174 MRF group, 150 usual care group, six centres each) received four pharmacist visits. Significant improvements were found for goal achievement in hypertension (OR 4.37, 95% confidence interval [CI] 2.54 to 7.51, P = .001), LDL cholesterol (OR 3.67, 95% CI 2.13 to 6.33, P = .001), type 2 diabetes (OR 6.97, 95% CI 3.69 to 13.2, P = .001), medication adherence (OR 6.60, 95% CI 1.36 to 31.9, P = .022), medications number (-0.86, 95% CI -1.14 to -0.58, P < .001) and CVD risk score (-2.27, 95% CI -2.84 to -1.69, P < .001). CONCLUSION: Pharmacist-led medication review with follow-up improved cardiovascular disease risk factor control and medication adherence. This study supports pharmacists' inclusion in primary care teams.

Cost-utility analysis of medication review with follow-up for cardiovascular outcomes: A microsimulation model.

BACKGROUND: Cardiovascular diseases are the leading cause of death. Pharmacist-led medication review with follow-up might be cost-effective preventing cardiovascular diseases. OBJECTIVE: To undertake a cost-utility analysis of the addition of pharmacist-led medication review with follow-up to usual care compared to usual care alone for cardiovascular outpatients. MATERIALS AND METHODS: A state-transition microsimulation model was built to project outcomes over a lifetime time horizon. Inputs from a cluster randomized controlled trial conducted in primary health care centers in Chile with full-time pharmacists were used. Probabilities were estimated using patient-level data. Utilities and costs associated with each health state were obtained from the literature, whereas the intervention costs were retrieved from the trial. The public third-party payer perspective was used. Uncertainty was evaluated through one-way and probabilistic sensitivity analyses. RESULTS: For the base case analysis, an incremental cost-effectiveness ratio of $963 per quality-adjusted life-year was observed which was considered cost-effective. The results were robust to sensitivity analyses and were driven by decreased cardiovascular events resulting in lower mortality. CONCLUSIONS: Medication review with follow-up was deemed a cost-effective addition to usual care with low uncertainty.

Medication review with follow-up for cardiovascular outcomes: a trial based cost-utility analysis.

Aim: To assess the trial-based cost-effectiveness of medication review with follow-up compared with usual care in primary care. Materials & methods: A cluster randomized controlled trial included patients if they were independent older adults, receiving five or more prescriptions, with moderate or high cardiovascular risk. Costs were estimated from the public healthcare sector perspective, and health benefits were measured as quality-adjusted life years. Both of which were used to calculate the incremental cost-effectiveness ratio. Results: Twelve centers completed the study, six (146 patients) in the intervention group and six (145 patients) in the control group. The base-case analysis showed an incremental cost-effectiveness ratio of US$ (2019) 434.4/quality-adjusted life year (95% CI 64.20-996.03). Conclusion: The intervention was cost-effective in the public primary care setting.

Primary health care pharmacists and vision for community pharmacy and pharmacists in Chile.

The Chilean healthcare system is composed of public and private sectors, with most of the higher-income population being covered privately. Primary healthcare in the public system is provided in more than 2,500 public primary care centers of different sizes with assigned populations within territories. Private insurance companies have their own healthcare networks or buy services from individual health providers. Patients from the public system receive most medications free of charge in primary care pharmacies embedded in each care center. Private patients must purchase their medicines from community pharmacies. Some government policies subsidize part of the cost of medications, but original medicines remain as the most expensive of Latin America. Three chain pharmacies have more than 90% of the market share, and these pharmacies have negative public perception because of price collusion court sentences. A non-profit, municipal pharmacy model was developed but has limited implementation. Most privately owned independent and chain community pharmacies do not provide pharmaceutical services as there is no remuneration or cover by insurers. The limited number of publicly owned Municipal pharmacies could implement pharmaceutical services in community settings as they are non-profit establishments and have full-time pharmacists but are not resourced for these services. A limited number of pharmaceutical services are almost exclusively provided in public primary care, including medication reviews, pharmaceutical education, home visits and pharmacovigilance services, but several barriers to their implementation remain. A risk-based multimorbidity care model was implemented in 2020 for public primary care with additional employment of part-time pharmacists to provide services. We believe that this model will help pharmacists to optimize their time by prioritizing the much-needed clinical tasks. We propose within this multimorbidity care model that the more time-consuming services are provided to higher risk patients. Pharmacy prescribing i.e. amending or approving changes in medications in primary care for chronic conditions could also be useful for the health system, but pharmacists would require additional training. The landscape for pharmaceutical services for primary care in Chile is promising, but the integration with community pharmacies will not be possible until they are funded by public and private insurance, and the public perception of these establishments is improved.

Systematic Review and Meta-Analysis of Medication Reviews Conducted by Pharmacists on Cardiovascular Diseases Risk Factors in Ambulatory Care.

Background Pharmacists-led medication reviews (MRs) are claimed to be effective for the control of cardiovascular diseases; however, the evidence in the literature is conflicting. The main objective of this meta-analysis was to analyze the impact of pharmacist-led MRs on cardiovascular disease risk factors overall and in different ambulatory settings while exploring the effects of different components of MRs. Methods and Results Searches were conducted in PubMed, Web of Science, Embase, the Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library Central Register of Controlled Trials database. Randomized and cluster randomized controlled trials of pharmacist-led MRs compared with usual care were included. Settings were community pharmacies and ambulatory clinics. The classification used for MRs was the Pharmaceutical Care Network Europe as basic (type 1), intermediate (type 2), and advanced (type 3). Meta-analyses in therapeutic goals used odds ratios to standardize the effect of each study, and for continuous data (eg, systolic blood pressure) raw differences were calculated using baseline and final values, with 95% CIs. Prediction intervals were calculated to account for heterogeneity. Sensitivity analyses were conducted to test the robustness of results. Meta-analyses included 69 studies with a total of 11 644 patients. Sample demographic characteristics were similar between studies. MRs increased control of hypertension (odds ratio, 2.73; 95% prediction interval, 1.05-7.08), type 2 diabetes mellitus (odds ratio, 3.11; 95% prediction interval, 1.17-5.88), and high cholesterol (odds ratio, 1.91; 95% prediction interval, 1.05-3.46). In ambulatory clinics, MRs produced significant effects in control of diabetes mellitus and cholesterol. For community pharmacies, systolic blood pressure and low-density lipoprotein values decreased significantly. Advanced MRs had larger effects than intermediate MRs in diabetes mellitus and dyslipidemia outcomes. Most intervention components had no significant effect on clinical outcomes and were often poorly described. CIs were significant in all analyses but prediction intervals were not in continuous clinical outcomes, with high heterogeneity present. Conclusions Intermediate and advanced MRs provided by pharmacists may improve control of blood pressure, cholesterol, and type 2 diabetes mellitus, as statistically significant prediction intervals were found. However, most continuous clinical outcomes failed to achieve statistical significance, with high heterogeneity present, although positive trends and effect sizes were found. Studies should use a standardized method for MRs to diminish sources of these heterogeneities.

Economic evaluations of pharmacist-led medication review in outpatients with hypertension, type 2 diabetes mellitus, and dyslipidaemia: a systematic review.

OBJECTIVES: To evaluate the health economics evidence based on randomized controlled trials of pharmacist-led medication review in pharmacotherapy managed cardiovascular disease risk factors, specifically, hypertension, type-2 diabetes mellitus and dyslipidaemia in ambulatory settings and to provide recommendations for future evaluations. METHODS: A systematic review was carried out according to the Cochrane Handbook for Systematic Reviews. PubMed (Medline), Scopus, Web of Science, National Health System Economic Evaluation Database (NHS EED), Cochrane Library, and Econlit were searched and screened by two independent authors. Incremental cost-effectiveness ratio was the main outcome. Risk of bias was assessed with the Effective Practice and Organisation of Care tool by the Cochrane Collaboration. Economic evaluation quality was assessed with the he Consensus Health Economic Criteria list (CHEC list). RESULTS: 5636 records were found, and 174 were retrieved for full-text review yielding 11 articles. Eight articles deemed the intervention as cost effective and two as dominant. Two cost-utility analyses were performed yielding ICERs of $612.7 and $59.8 per QALY. Four articles were considered to perform a high-quality economic evaluation and four had a low risk of bias. Future economic evaluations should consider cost-utility analysis, to describe usual care thoroughly, and use time horizons that capture the effect of cardiovascular disease prevention, a societal perspective and uncertainty analysis. CONCLUSION: Pharmacist-led medication review has proven to be cost effective in various studies in different settings. Policy decision makers are advised to undertake local economic evaluations reflecting the gaps observed in this systematic review and published literature. If this is not possible, a transferability assessment should be conducted.
