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

ABSTRACT: 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.

Project description:BackgroundThe health risks associated with poor medication practices in the home suggest that patients would benefit from home-based medication reviews that could detect and resolve these issues. However, remuneration for home visits often excludes ambulatory, nonhomebound patients. A subset of these patients have issues that cannot be adequately identified and resolved during the course of a typical pharmacy-based medication review.PurposeThis study aims to characterize the prevalence and nature of "hidden in the home" medication management issues in nonhomebound patients.MethodsPharmacists facilitated subject enrollment among patients at 6 community pharmacies in Toronto over a 15-month period, from January 2016 to March 2017. Patients taking 5 or more chronic medications who were ambulatory (able to visit the pharmacy) and scored 3 points or higher on a prescreening questionnaire were invited to participate. Visits included a standard medication review, the identification of drug therapy problems and an assessment of the patient's medication and organization/storage practices, followed by a medication cabinet cleanup.ResultsOne hundred patients were recruited, with a mean age of 76.9 years and taking on average 10 chronic medications. Pharmacists identified a total of 275 drug therapy problems (2.75 per patient). The most common issues reported additional therapy required (23.6%), nonadherence (23.3%) and adverse drug reactions (17.8%). For those patients 65 years or older (87%), 32% were found to be using at least 1 medication on the Beers Criteria list, while 6% were using 3 or more. Sulfonylureas, non-steroidal anti-inflammatory drugs and short-acting benzodiazepines were the most commonly implicated drugs. Medications were removed from the homes of 67% of the patients, with expiry of medication being the most common reason for removal (54.2%). The mean duration of a home visit was 49.5 minutes.ConclusionPharmacist-directed home medication reviews offer an effective mechanism to address the pharmacotherapy issues of patients taking multiple medications. These findings highlight the frequency of medication management issues in this group and suggest that home medication reviews could serve to minimize inappropriate use of medication and maximize health care cost savings in this unique patient population.

Project description:ObjectiveTo (1) characterize community pharmacists' and community pharmacy residents' decision making and unmet information needs when conducting comprehensive medication reviews (CMRs) as part of medication therapy management and (2) explore any differences between community pharmacists and community pharmacy residents in CMR decision making and unmet information needs.DesignThirty-to 60-minute semistructured interviews framed using a clinical decision-making model (CDMM) were conducted with community pharmacists and residents.Setting and participantsParticipants were recruited from practice-based research networks and researchers' professional networks. Eligible participants had completed or supported the completion of at least 2 CMRs in the last 30 days.Outcome measuresTwo researchers independently coded transcripts using a combination of inductive and deductive methods to identify themes pertaining to community pharmacists' and residents' decision making and unmet information needs in the provision of CMRs. Discrepancies among researchers' initial coding decisions were resolved through discussion.ResultsSixteen participants (8 pharmacists and 8 residents) were interviewed. Themes were mapped to 5 CDMM steps. Participants primarily used subjective information during "case familiarization"; objective information was secondary. Information used for "generating initial hypotheses" varied by medication therapy problem (MTP) type. During "case assessment," if information was not readily available, participants sought information from patients. Thus, patients' levels of self-management and health literacy influenced participants' ability to identify and resolve MTPs, as described under "identifying final hypotheses." Finally, participants described "decision-making barriers," including communication with prescribers to resolve MTPs. Although pharmacist and resident participants varied in the types of MTPs identified, both groups cited the use and need of similar information.ConclusionCommunity pharmacists and residents often rely primarily on patient-provided information for decision making during CMRs because of unmet information needs, specifically, objective information. Moreover, confidence in MTP identification and resolution is reduced by communication challenges with prescribers and limitations in patients' ability to convey accurate and necessary information.

Project description:BACKGROUND:Medication reviews are recognized services to increase quality of therapy and reduce medication risks. The selection of eligible patients with potential to receive a major benefit is based on assumptions rather than on factual data. Acceptance of interprofessional collaboration is crucial to increase the quality of medication therapy. OBJECTIVE:The research question was to identify and prioritize eligible patients for a medication review and to provide evidence-based criteria for patient selection. Acceptance of the prescribing general practitioner to implement pharmaceutical recommendations was measured and factors influencing physicians' acceptance were explored to obtain an impression on the extent of collaboration in medication review in an ambulatory care setting. METHODS:Based on data of a cluster-randomized controlled study (WestGem-study), the correlation between patient parameters and the individual performance in a medication review was calculated in a multiple logistic regression model. Physician's acceptance of the suggested intervention was assessed using feedback forms. Influential factors were analyzed. RESULTS:The number of drugs in use (p = 0.001), discrepancies between prescribed and used medicines (p = 0.014), the baseline Medication Appropriateness Index score (p<0.001) and the duration of the intervention (p = 0.006) could be identified as influential factors for a major benefit from a medication review, whereas morbidity (p>0.05) and a low kidney function (p>0.05) do not predetermine the outcome. Longitudinal patient care with repeated reviews showed higher interprofessional acceptance and superior patient benefit. A total of 54.9% of the recommendations in a medication review on drug therapy were accepted for implementation. CONCLUSIONS:The number of drugs in use and medication reconciliation could be a first rational step in patient selection for a medication review. Most elderly, multimorbid patients with polymedication experience a similar chance of receiving a benefit from a medication review. Longitudinal patient care should be preferred over confined medication reviews. The acceptance of medication reviews by physicians supports further implementation into health care systems.

Project description:The available evidence on the effects of ambient air pollution on cardiovascular diseases (CVDs) has increased substantially. In this umbrella review, we summarized the current epidemiological evidence from systematic reviews and meta-analyses linking ambient air pollution and CVDs, with a focus on geographical differences and vulnerable subpopulations. We performed a search strategy through multiple databases including articles between 2010 and 31 January 2021. We performed a quality assessment and evaluated the strength of evidence. Of the 56 included reviews, the most studied outcomes were stroke (22 reviews), all-cause CVD mortality, and morbidity (19). The strongest evidence was found between higher short- and long-term ambient air pollution exposure and all-cause CVD mortality and morbidity, stroke, blood pressure, and ischemic heart diseases (IHD). Short-term exposures to particulate matter <2.5 μm (PM2.5 ), <10 μm (PM10 ), and nitrogen oxides (NOx ) were consistently associated with increased risks of hypertension and triggering of myocardial infarction (MI), and stroke (fatal and nonfatal). Long-term exposures of PM2.5 were largely associated with increased risk of atherosclerosis, incident MI, hypertension, and incident stroke and stroke mortality. Few reviews evaluated other CVD outcomes including arrhythmias, atrial fibrillation, or heart failure but they generally reported positive statistical associations. Stronger associations were found in Asian countries and vulnerable subpopulations, especially among the elderly, cardiac patients, and people with higher weight status. Consistent with experimental data, this comprehensive umbrella review found strong evidence that higher levels of ambient air pollution increase the risk of CVDs, especially all-cause CVD mortality, stroke, and IHD. These results emphasize the importance of reducing the alarming levels of air pollution across the globe, especially in Asia, and among vulnerable subpopulations.

Project description:BackgroundNon-adherence negatively affects the efficacy, safety and costs of therapies. Non-adherence is a multifactorial problem. This systematic review (SR) of SRs (overview) aims to identify factors that can influence the adherence of adult patients with chronic physical diseases.MethodsWe performed a systematic literature search in MEDLINE and Embase on June 13, 2018. We included SRs on the factors that can influence adherence in adult patients taking oral medications for treating physical chronic diseases. Two reviewers independently selected studies according to pre-defined inclusion criteria. Two reviewers independently assessed the risk of bias with the ROBIS tool. Data were extracted in standardized tables previously piloted by one reviewer and verified by a second reviewer. We synthesized data in tables in a structured narrative manner.ResultsWe included 21 SRs on eight different conditions. We rated eight SRs to be at low risk of bias and 13 to be at high risk of bias. Although higher education, employment, higher financial status and marriage/partnership mostly showed a positive effect on adherence, the impact was unclear because of the high uncertainty of the underlying evidence. The evidence indicates that socioeconomic status and social support might have a positive impact on adherence and that belonging to an ethnic minority might have a negative impact on adherence. Therapy-related factors (e.g., intake regime) and disease-related factors (e.g., duration) mostly showed no impact on adherence. Analysis of gender showed inconsistent results. Age might have a concave relation to adherence, i.e., adherence is lowest in very young and very old people. Depression has a negative impact on adherence. Impacts of other mental and physical comorbidities were uncertain. Co-payments (any or higher) have a negative impact on adherence. In contrast, the impacts of medication costs and insurance status were uncertain.ConclusionThis overview analyses factors that might impact adherence to oral therapies in adult patients with physical chronic diseases. Our overview suggests that there is a social gradient in adherence. However, for most factors, the evidence was not conclusive due to the risk of bias, inconsistency or imprecision.
