Physician-pharmacist cooperation program for blood pressure control in patients with hypertension: a randomized-controlled trial

Involving community pharmacists in interprofessional collaboration in primary care: a systematic review

BACKGROUND

The World Health Organization supports interprofessional collaboration in primary care. On over the past 20 years, community pharmacists had been taking a growing number of new responsibilities and they are recognized as a core member of collaborative care teams as patient-centered care providers. This systematic review aimed to describe interprofessional collaboration in primary care involving a pharmacist, and its effect on patient related outcomes.

METHODS

A systematic review of randomized controlled trials cited in the MEDLINE, EMBASE, PsycInfo and CINAHL in English and French was conducted from inception to November 2022. Studies were included if they described an intervention piloted by a primary care provider and included a pharmacist and if they evaluated the effects of intervention on a disease or on patient related outcomes. The search generated 3494 articles. After duplicates were removed and titles and abstracts screened for inclusion, 344 articles remained.

RESULTS

Overall, 19 studies were included in the review and assessed for quality. We found 14 studies describing an exclusive collaboration between physician and pharmacist with for all studies a three-step model of pharmacist intervention: a medication review, an interview with the patient, and recommendations made to physician. Major topics in the articles eligible for inclusion included cardiovascular diseases with blood pressure, diabetes, dyslipidemia, and risk of cardiovascular diseases. Positive effects concerned principally blood pressure.

CONCLUSIONS

Collaboration involving pharmacists is mainly described in relation to cardiovascular diseases, for which patient-centered indicators are most often positive. It underscores the need for further controlled studies on pharmacist-involved interprofessional collaboration across various medical conditions to improve consensus on core outcomes measures.

Interprofessional collaboration in primary care: what effect on patient health? A systematic literature review

BACKGROUND

In a period of change in the organization of primary care, Interprofessional Collaboration (IPC) is presented as one of the solutions to health issues. Although the number of inter-professional interventions grounded in primary care increases in all developed countries, evidence on the effects of these collaborations on patient-centred outcomes is patchy. The objective of our study was to assess the effects of IPC grounded in the primary care setting on patient-centred outcomes.

METHODS

We conducted a systematic literature review using the PubMed, Embase, PsycINFO and CINAHL databases from 01/01/1995 to 01/03/2021, according to the PRISMA guidelines. Studies reporting the effects of IPC in primary care on patient health outcomes were included. The quality of the studies was assessed using the revised Downs and Black checklist.

RESULTS

Sixty-five articles concerning 61 interventions were analysed. A total of 43 studies were prospective and randomized. Studies were classified into 3 main categories as follows: 1) studies with patients at cardiovascular risk (28 studies)-including diabetes (18 studies) and arterial hypertension (5 studies); 2) studies including elderly and/or polypathological patients (18 studies); and 3) patients with symptoms of mental or physical disorders (15 studies). The number of included patients varied greatly (from 50 to 312,377). The proportion of studies that reported a positive effect of IPC on patient-centred outcomes was as follows: 23 out of the 28 studies including patients at cardiovascular risk, 8 out of the 18 studies of elderly or polypathological patients, and 11 out of the 12 studies of patients with mental or physical disorders.

CONCLUSIONS

Evidence suggests that IPC is effective in the management of patients at cardiovascular risk. In elderly or polypathological patients and in patients with mental or physical disorders, the number of studies remains very limited, and the results are heterogeneous. Researchers should be encouraged to perform studies based on comparative designs: it would increase evidence on the positive effect and benefits of IPC on patient variables.

Is lifestyle modification with individual face-to-face education and counseling more effective than usual care for controlling hypertension? A systematic review and meta-analysis of randomized controlled trials

Hypertension (HTN) management continues to be a concern due to challenges with behavioral risk factors. Patient education to modify unhealthy behaviors appears to be effective in managing HTN. Therefore, this meta-analysis aimed to determine whether individualized face-to-face education and counseling have a beneficial effect on systolic and diastolic blood pressure (SBP and DBP) in hypertensive patients. Studies were extracted from PubMed, Scopus, Cochrane Library, and Web of Science databases. Nine studies, comprising 2627 participants, were included. Random effects models were used to pool estimates of mean differences (MDs) with 95% confidence intervals (CIs) in SBP and DBP between the intervention and usual care groups. SBP and DBP were significantly reduced at the 6-month (MD = -4.38 mmHg, 95% CI: -6.95 to -1.81; MD = -2.09 mmHg, 95% CI: -3.69 to -0.50, respectively) and 12-month time points (MD = -2.48 mmHg, 95% CI: -3.96 to -1.01; MD = -1.71 mmHg, 95% CI: -2.88 to -0.55, respectively) with intervention. At the 24-month time point, there was a significant change in SBP (MD = -2.13 mmHg, 95% CI: -3.94 to -0.32) with intervention compared with the usual care group. This study showed that individualized face-to-face education and counseling add significant benefits to usual care for lowering blood pressure in hypertensive patients. Graphical Abstract.

Effect of Medication Therapy Management by Pharmaceutical Care on Blood Pressure and Cardiovascular Risk in Hypertension: A Systematic Review, Meta-Analysis, and Meta-Regression

Medication therapy management by pharmaceutical care (MTM-PC) has been shown to improve the effectiveness of antihypertensive treatments. The aim was to answer the question: what are the MTM-PC models and their impact on hypertensive patients' outcomes? This is a systematic review with meta-analysis. The search strategies were run on 27 September 2022 in the following databases: PubMed, EMBASE, Scopus, LILACs, Central Cochrane Library, Web of Science; and International Pharmaceutical Abstracts. The quality and bias risk was assessed by the Downs and Black instrument. Forty-one studies met the eligibility criteria and were included, Kappa = 0.86; 95% CI, 0.66-1.0; (p < 0.001). Twenty-seven studies (65.9%) had MTM-PC models outlined by the clinical team, showing as characteristics the mean of 10.0 ± 10.7 months of follow-up of hypertensive patients, with 7.7 ± 4.9 consultations. Instruments to assess the quality of life measured the enhancement by 13.4 ± 10.7% (p = 0.047). The findings of the meta-analysis show a mean reduction of -7.71 (95% CI, -10.93 to -4.48) and -3.66 (95% CI, -5.51 to -1.80), (p < 0.001) in mmHg systolic and diastolic pressures, respectively. Cardiovascular relative risk (RR) over ten years was 0.561 (95% CI, 0.422 to 0.742) and RR = 0.570 (95% CI, 0.431 to 0.750), considering homogeneous studies, I² = 0%. This study shows the prevalence of MTM-PC models outlined by the clinical team, in which there are differences according to the models in reducing blood pressure and cardiovascular risk over ten years with the improvement in quality of life.

Development and acceptance of a new adherence monitoring package to identify non-adherent patients with polypharmacy in primary care: a feasibility study

BACKGROUND

Adherence to pharmacotherapy is crucial to prevent symptom deterioration in chronic diseases. However, non-adherence to chronic treatments is prevalent, especially in polypharmacy. Practical tools to assess adherence to polypharmacy in primary care are missing.

AIMS

We aimed to develop an Adherence Monitoring Package (AMoPac) for general practitioners (GPs) to identify patient non-adherence. We tested the feasibility and acceptance of AMoPac in the primary healthcare setting.

METHODS

AMoPac was developed based on peer-reviewed literature. It consists in (1) electronic monitoring of patients' medication intakes for 4 weeks, (2) receiving feedback on intake behaviour by the pharmacist and (3) generating an adherence report to communicate to the GPs. A feasibility study was conducted with heart failure patients. GPs' acceptance of AMoPac was explored with semistructured interviews. Electronic transmission of the reports into the GP's electronic health record along with laboratory reports stating N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels was analysed.

RESULTS

We developed AMoPac and tested its feasibility with six GPs and seven heart failure patients. GPs were satisfied with the adherence report including the pharmaceutical-clinical recommendations. Integrated transmission of adherence reports to GPs was not feasible due to technical incompatibilities. Mean taking adherence was 86.4%±12.8% and three patients had low correct dosing-days (69%, 38% and 36%, respectively). NT-proBNP ranged from 102 to 8561 pg/mL and four patients had elevated values (>1000 pg/mL).

CONCLUSION

AMoPac is feasible in the primary healthcare setting, excluding the integrated transmission of adherence reports to GPs. The procedure was highly accepted by GPs and patients. AMoPac fills a gap by combining clinical values with adherence data, and therefore, delivers a multifaceted picture of the patient's behaviour. In case of unmet adherence, our tool might facilitate the selection of patient-centred approaches to optimise pharmacological therapies in chronic heart failure patients.

Effects of Pharmacist Intervention on Community Control of Hypertension: A Randomized Controlled Trial in Zunyi, China

OBJECTIVE

We aimed to test the effects of pharmacist intervention on the community control of hypertension through a comparative randomized controlled trial.

METHODS

We recruited adult hypertensive patients with comorbidity or confusion with medication (n=636) from 2 community health centers in Zunyi, China. They were randomly and equally divided into 2 groups. Both groups received the usual care and participated in the community systematic management program of hypertension. Participants in the intervention group were given interventions from pharmacists, including a monthly review of medications, patient education, and medication adjustment advice to medical doctors over 6 months. Participants' blood pressure was assessed at baseline, 3 months, and 6 months. Participants' knowledge and medication adherence were measured using a questionnaire before and after the trial.

RESULTS

Compared to the control group (n=298), a significantly higher percentage of participants in the intervention group (n=290) had their blood pressure under control 3 months (46.9% vs. 38.3%, P=.034) and 6 months (60.7% vs. 40.9%, P<.001) after the interventions. Difference-in-differences analyses showed that the pharmacist intervention resulted in an increase in knowledge scores by 12.55 points (P<.001), a decrease in systolic blood pressure by 6.65 mmHg (P=.001), and a decrease in diastolic blood pressure by 7.26 mmHg (P<.001) compared to the controls after adjustment for variations in potential confounding factors. The odds of participants passing the hypertension knowledge tests in the intervention group was 4.45 times those in the control group (P<.001). Similarly, it was found that the intervention group had higher odds of not needing any medication adjustments (adjusted odds ratio [AOR]=2.75, P<.001) and having their blood pressure under control (AOR=2.18, P=.002) compared to the control group.

CONCLUSION

It is evident that pharmacist intervention has significant short-term effects on improving the knowledge and medication adherence of hypertensive patients, as well as timely medication adjustments from medical doctors, resulting in lowered blood pressure and an increased control rate. Further studies should explore the long-term sustainability of the effects of community pharmacist intervention.

Risk Classification for Metabolic Syndrome and the Incidence of Cardiovascular Disease in Japan With Low Prevalence of Obesity: A Pooled Analysis of 10 Prospective Cohort Studies

Background It is uncertain whether risk classification under the nationwide program on screening and lifestyle modification for metabolic syndrome captures well high-risk individuals who could benefit from lifestyle interventions. We examined the validity of risk classification by linking the incidence of cardiovascular disease (CVD). Methods and Results Individual-level data of 29 288 Japanese individuals aged 40 to 74 years without a history of CVD from 10 prospective cohort studies were used. Metabolic syndrome was defined as the presence of high abdominal obesity and/or overweight plus risk factors such as high blood pressure, high triglyceride or low high-density lipoprotein cholesterol levels, and high blood glucose levels. The risk categories for lifestyle intervention were information supply only, motivation-support intervention, and intensive support intervention. Sex- and age-specific hazard ratios and population attributable fractions of CVD, which were also further adjusted to consider non-high density lipoprotein cholesterol levels, were estimated with reference to nonobese/overweight individuals, using Cox proportional hazard regression. Since the reference category included those with risk factors, we set a supernormal group (nonobese/overweight with no risk factor) as another reference. We documented 1023 incident CVD cases (565 men and 458 women). The adjusted CVD risk was 60% to 70% higher in men and women aged 40 to 64 years receiving an intensive support intervention, and 30% higher in women aged 65 to 74 years receiving a motivation-support intervention, compared with nonobese/overweight individuals. The population attributable fractions in men and women aged 40 to 64 years receiving an intensive support intervention were 17.7% and 6.6%, respectively, while that in women aged 65 to 74 years receiving a motivation-support intervention was 9.4%. Compared with the supernormal group, nonobese/overweight individuals with risk factors had similar hazard ratios and population attributable fractions as individuals with metabolic syndrome. Conclusions Similar CVD excess and attributable risks among individuals with metabolic syndrome components in the absence and presence of obesity/overweight imply the need for lifestyle modification in both high-risk groups.

Development of a primary care pharmacy outcomes framework: An umbrella literature review

BACKGROUND

An aging population and rising multi-morbidity has shifted healthcare provision from secondary to primary care. Pharmacy-led services have been introduced to support this. The development of an outcomes framework for these services would facilitate conclusions to be drawn on their effectiveness.

OBJECTIVES

To identify outcomes used to evaluate pharmacy-led medication therapy and disease management services within primary care settings to develop an outcomes framework for future studies.

METHODS

An umbrella literature review was conducted. MEDLINE, EMBASE, The Cochrane Library and PsycINFO were searched in June 2020 to identify relevant articles. Eligible reviews were those including studies published from 2010 onwards which reported on the outcomes of pharmacy-led medication therapy and disease management services within primary care, excluding community pharmacy settings. Data were extracted and a content analysis, guided by the ECHO model, stratified the outcomes into four areas: economic, clinical, humanistic and service.

RESULTS

Twenty-four reviews covering 52 unique studies were identified. Pharmacy-led services included: medication reviews (n=24, 46.2%), disease and therapy management (n=17, 32.7%), educational services (n=6, 11.5%), medicines reconciliation (n=3, 5.8%), and medication compliance support (n=1, 1.9%). Services were commonly targeted towards endocrine (n=23, 44.2%) or cardiovascular diseases (n=20, 38.5%). Outcomes most commonly explored were clinical (n=38, 73.1%) and service outcomes (n=37, 71.2%), followed by humanistic (n=23, 44.2%) and economic outcomes (n=13, 25.0%). Overall, 17 sub-categories of outcomes were identified; common sub-categories were: disease indicators [clinical]; medication use and healthcare utilisation [service]; adherence to medicines [humanistic]; and healthcare costs [economic].

CONCLUSIONS

The findings informed the development of an outcomes framework to guide the evaluation of medication therapy and disease management services, and facilitate international standardised outcome measures within primary care pharmacy to be developed. This could help offer vital evidence on the effectiveness of these services to ensure the pharmacy workforce is working optimally to support primary care.

Assessment of the educational competencies for the Hypertension Canada Professional Certification Program (HC-PCP) designed for implementation of hypertension guidelines into primary care

BACKGROUND

The uptake of clinical practice guidelines into practice is limited for many chronic conditions, including hypertension. The aim of this study was to ascertain the importance of the educational competencies for the development of the Hypertension Canada Professional Certification Program (HC-PCP) among frontline, primary care professionals (e.g., pharmacists, physicians, nurses).

METHODS

A group of hypertension experts developed 15 competencies believed to be important for primary care professionals to master when providing hypertension management. These competencies were surveyed for consensus by frontline clinicians through the Hypertension Canada e-newsletter in 2018. Clinicians were asked to rank the importance of each competency for a primary care provider to acquire when undertaking a certification in hypertension management, using a Likert scale from 1 (not important) to 5 (very important).

RESULTS

A total of 121 clinicians responded to the survey. Of these, 38% were pharmacists, 31.4% were registered nurses, 10.7% were physicians and 7% were nurse practitioners. There was at least 1 respondent from each Canadian province and territory, except for the Northwest Territories. All 15 competencies received a mean rank of at least 4. The competency with the highest ranking was Competency 6: Ability to screen and identify hypertension (mean 4.83 [0.04]). The competencies with the lowest average ranks were Competency 1: Demonstrates a sound knowledge of the epidemiology of hypertension (mean 4.07 [0.85]) and Competency 5: Demonstrates an understanding of the validation process for blood pressure devices (mean 4.15 [0.08]).

CONCLUSIONS

Clinicians generally ranked all 15 competencies to be of high importance for a provider who is certified in hypertension management to possess. These competencies and the current Hypertension Canada guidelines were used as the foundation for the development of an education program called the Hypertension Canada Professional Certification Program.

Healthcare professional-led interventions on lifestyle modifications for hypertensive patients - a systematic review and meta-analysis

BACKGROUND

About 0.9 billion people in the world have hypertension. The mortality due to hypertension increased dramatically over the last decades. Healthcare professionals should support patients with hypertension to modify their lifestyle to decrease blood pressure, but an overview of effective lifestyle interventions is lacking. The aim of this study was to determine whether healthcare professional-led interventions on lifestyle modifications are effective in lowering blood pressure in patients with hypertension.

METHODS

A systematic literature review following the PRISMA guidelines was conducted. PubMed, EMBASE and CINAHL databases were searched for randomized control trials (RCTs) of interventions on lifestyle modifications of hypertensive patients which were performed by healthcare professionals (physician, nurse, pharmacist) and which reported blood pressure measurements. Papers were reviewed by two reviewers and analysed using Cochrane software Revman 5.4. In a meta-analysis difference in systolic blood pressure (SBP), diastolic blood pressure (DBP) and the percentage of patients with controlled blood pressure (BP) was analysed.

RESULTS

In total, 34 clinical trials reporting on 22,419 patients (mean age 58.4 years, 49.14% female, 69.9% used antihypertensive medications) were included. The mean difference SBP was - 4.41 mmHg (95% CI, - 5.52to - 3.30) and the mean difference DBP was - 1.66 mmHg (95% CI - 2.44 to - 0.88) in favor of the intervention group vs usual care. Fifty-six percent of patients achieved BP control in the intervention group vs 44% in usual care, OR = 1.87 (95% CI, 1.51 to 2.31).

CONCLUSION

Healthcare professional-led interventions were effective. Patients achieved almost 5 mmHg decrease of SBP and more patients achieved BP control. The results suggest that efforts are needed for widespread implementation.

Community Pharmacist Services for Hypertensive Patients: A Novel Practice in Shanghai, China

For Chinese community pharmacists, there is a lack of guidance before and after the drug treatment process for community residents. This study aimed to investigate community pharmacists' role in hypertension management. One hundred ninety-six hypertensive patients were randomly selected from the studied community. For patients in the intervention group, monthly meetings were scheduled with a community pharmacist. Patients in the non-intervention group received standard care from their physicians. In the intervention group, the percentage using information from pharmacists increased significantly, from 54.3% to 94.2% (P < .05). Awareness of self-management was also enhanced, with community self-management group attendance increasing from 53.4% to 77.7% (P < .05), but the non-intervention group did not change significantly. Hypertensive patients' beliefs about community pharmacists also improved significantly. Hypertension status also showed a significant improvement, whereas for participants without intervention, it worsened over time. In addition to increasing knowledge regarding drug use, care provided by community pharmacists can also significantly improve blood pressure status. For those who did not receive intervention, a disproportionate level of health deterioration could be seen.

Benefits of medication charts provided at transitions of care: a narrative systematic review

OBJECTIVES

Particularly at transitions of care points information concerning current medication tends to be incomplete. A medication chart that contains all essential information on current therapy is likely to be a helpful tool for patients and healthcare providers. We aimed to investigate any type of benefits associated with medication charts provided at transition points.

METHODS

A systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed. Two databases, two online journals and two association websites dedicated to biomedicine and pharmacy issues were consulted to identify studies for the review using the search term 'medication chart' and synonyms. We run our search from database inception up to March 2019. Studies of any study design, intervention and population which examined the effect of paper-based medication charts were included. We extracted study results narratively and coded and classified them by themes and categories inductively by using the 'framework method' with content analysis. The methodological quality of the studies was assessed using the Effective Public Health Practice Project (EPHPP) tool.

RESULTS

From the 846 retrieved articles, 30 studies met the inclusion criteria, mostly from Germany (18 studies) and the USA (5 studies). Thirteen studies reported a statistically significant result. In the 'patient theme', the most obvious benefits were an increase in medication knowledge, a reduction of medication errors and higher medication adherence. In the 'interdisciplinary theme', a medication chart represented a helpful tool to increase communication and inter-sectoral cooperation between healthcare providers. In the 'theme of terms and conditions', accuracy and currency of data are prerequisites for any positive effect. The quality of the studies was classified predominantly weak mainly due to unmet good quality criteria (no randomised controlled trials study design, no reported dropouts).

CONCLUSION

Overall, the reviewed studies suggested some benefits when using medication charts. Healthcare providers could consider using medication charts in their counselling practice. However, it is unknown whether the reported benefits lead to measurable improvement in clinical outcomes. PROSPERO REGISTRATION NUMBER.

Identifying contexts and mechanisms in multiple behavior change interventions affecting smoking cessation success: a rapid realist review

Background

Smoking continues to be a leading cause of preventable chronic disease-related morbidity and mortality, excess healthcare expenditure, and lost work productivity. Tobacco users are disproportionately more likely to be engaging in other modifiable risk behaviours such as excess alcohol consumption, physical inactivity, and poor diet. While hundreds of interventions addressing the clustering of smoking and other modifiable risk behaviours have been conducted worldwide, there is insufficient information available about the context and mechanisms in these interventions that promote successful smoking cessation. The aim of this rapid realist review was to identify possible contexts and mechanisms used in multiple health behaviour change interventions (targeting tobacco and two or more additional risk behaviours) that are associated with improving smoking cessation outcome.

Methods

This realist review method incorporated the following steps: (1) clarifying the scope, (2) searching for relevant evidence, (3) relevance confirmation, data extraction, and quality assessment, (4) data analysis and synthesis.

Results

Of the 20,423 articles screened, 138 articles were included in this realist review. Following Michie et al.’s behavior change model (the COM-B model), capability, opportunity, and motivation were used to identify the mechanisms of behaviour change. Universally, increasing opportunities (i.e. factors that lie outside the individual that prompt the behaviour or make it possible) for participants to engage in healthy behaviours was associated with smoking cessation success. However, increasing participant’s capability or motivation to make a behaviour change was only successful within certain contexts.

Conclusion

In order to address multiple health behaviours and assist individuals in quitting smoking, public health promotion interventions need to shift away from ‘individualistic epidemiology’ and invest resources into modifying factors that are external from the individual (i.e. creating a supportive environment).

Effectiveness of Educational Interventions on Adherence to Lifestyle Modifications Among Hypertensive Patients: An Integrative Review

Controlling blood pressure is a global concern as it is a major risk factor for cardiometabolic diseases and stroke. A flattened control rate was noted in recent decades, which highlighted an issue of adherence to medications and lifestyle modifications. Effectiveness of educational intervention on medication adherence and blood pressure control had been reviewed, but reviews on lifestyle modifications are lacking. This review with meta-analysis aimed to identify the effect of educational interventions on blood pressure control and adherence to lifestyle modifications. In accordance with the PRISMA statement, a search of CINAHL Complete, PubMed, Medline, Embase and Scopus for randomized control trials published between 2009 and 2019 was conducted. Data were extracted for quality synthesis and meta-analysis. Thirteen studies were included. Two forms of educational intervention, individual and group education, were commonly used. Phone calls, message reminders and reading materials after education were identified in the studies as supportive methods, which showed a moderate to large effect on adherence to lifestyle modifications and blood pressure control. Monthly group education lasting 45 min was suggested. Health professionals could integrate the education with supportive methods into community health promotion to improve and reinforce the adherence behavior on medications and lifestyle modifications among hypertensive patients.

Community pharmacy interventions for health promotion: effects on professional practice and health outcomes

BACKGROUND

Community pharmacies are an easily accessible and cost-effective platform for delivering health care worldwide, and the range of services provided has undergone rapid expansion in recent years. Thus, in addition to dispensing medication, pharmacy workers within community pharmacies now give advice on a range of health-promoting behaviours that aim to improve health and to optimise the management of long-term conditions. However, it remains uncertain whether these health-promotion interventions can change the professional practice of pharmacy workers, improve health behaviours and outcomes for pharmacy users and have the potential to address health inequalities.

OBJECTIVES

To assess the effectiveness and safety of health-promotion interventions to change community pharmacy workers' professional practice and improve outcomes for users of community pharmacies.

SEARCH METHODS

We searched MEDLINE, Embase, CENTRAL, six other databases and two trials registers to 6 February 2018. We also conducted reference checking, citation searches and contacted study authors to identify any additional studies.

SELECTION CRITERIA

We included randomised trials of health-promotion interventions in community pharmacies targeted at, or delivered by, pharmacy workers that aimed to improve the health-related behaviour of people attending the pharmacy compared to no treatment, or usual treatment received in the community pharmacy. We excluded interventions where there was no interaction between pharmacy workers and pharmacy users, and those that focused on medication use only.

DATA COLLECTION AND ANALYSIS

We used standard procedures recommended by Cochrane and the Effective Practice and Organisation of Care review group for both data collection and analysis. We compared intervention to no intervention or to usual treatment using standardised mean differences (SMD) and 95% confidence intervals (95% CI) (higher scores represent better outcomes for pharmacy user health-related behaviour and quality of life, and lower scores represent better outcomes for clinical outcomes, costs and adverse events). Interpretation of effect sizes (SMD) was in line with Cochrane recommendations.

MAIN RESULTS

We included 57 randomised trials with 16,220 participants, described in 83 reports. Forty-nine studies were conducted in high-income countries, and eight in middle-income countries. We found no studies that had been conducted in low-income countries. Most interventions were educational, or incorporated skills training. Interventions were directed at pharmacy workers (n = 8), pharmacy users (n = 13), or both (n = 36). The clinical areas most frequently studied were diabetes, hypertension, asthma, and modification of cardiovascular risk. Duration of follow-up of interventions was often unclear. Only five studies gave details about the theoretical basis for the intervention, and studies did not provide sufficient data to comment on health inequalities. The most common sources of bias were lack of protection against contamination - mainly in individually randomised studies - and inadequate blinding of participants. The certainty of the evidence for all outcomes was moderate. We downgraded the certainty because of the heterogeneity across studies and evidence of potential publication bias. Professional practice outcomes We conducted a narrative analysis for pharmacy worker behaviour due to high heterogeneity in the results. Health-promotion interventions probably improve pharmacy workers' behaviour (2944 participants; 9 studies; moderate-certainty evidence) when compared to no intervention. These studies typically assessed behaviour using a simulated patient (mystery shopper) methodology. Pharmacy user outcomes Health-promotion interventions probably lead to a slight improvement in health-related behaviours of pharmacy users when compared to usual treatment (SMD 0.43, 95% CI 0.14 to 0.72; I² = 89%; 10 trials; 2138 participants; moderate-certainty evidence). These interventions probably also lead to a slight improvement in intermediate clinical outcomes, such as levels of cholesterol or glycated haemoglobin, for pharmacy users (SMD -0.43, 95% CI -0.65 to -0.21; I² = 90%; 20 trials; 3971 participants; moderate-certainty evidence). We identified no studies that evaluated the impact of health-promotion interventions on event-based clinical outcomes, such as stroke or myocardial infarction, or the psychological well-being of pharmacy users. Health-promotion interventions probably lead to a slight improvement in quality of life for pharmacy users (SMD 0.29, 95% CI 0.08 to 0.50; I²= 82%; 10 trials, 2687 participants; moderate-certainty evidence). Adverse events No studies reported adverse events for either pharmacy workers or pharmacy users. Costs We found that health-promotion interventions are likely to be cost-effective, based on moderate-certainty evidence from five of seven studies that reported an economic evaluation.

AUTHORS' CONCLUSIONS

Health-promotion interventions in the community pharmacy context probably improve pharmacy workers' behaviour and probably have a slight beneficial effect on health-related behaviour, intermediate clinical outcomes, and quality of life for pharmacy users. Such interventions are likely to be cost-effective and the effects are seen across a range of clinical conditions and health-related behaviours. Nevertheless the magnitude of the effects varies between conditions, and more effective interventions might be developed if greater consideration were given to the theoretical basis of the intervention and mechanisms for effecting behaviour change.

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.

Changes in community pharmacists' knowledge, attitudes, and practice regarding the management of hypertension before and after educational interventions

Objective: To clarify changes in community pharmacists' knowledge, attitudes, and practice regarding the management of hypertension before and after attending educational interventions based on their self-report on a questionnaire survey.Method: We conducted questionnaire surveys regarding the management of hypertension with a sample of community pharmacists before and after educational interventions.Results: The proportions of pharmacists who knew the 2014 Japanese Society of Hypertension Guidelines, guidelines for home blood pressure measurement, reference values for hypertension based on clinic-measured blood pressure, and reference values for hypertension based on home-measured blood pressure after the educational interventions (59.3%, 41.4%, 75.1%, and 70.8% respectively) were significantly higher relative to those recorded before interventions (31.6%, 13.7%, 47.7%, and 25.4% respectively).Conclusions: These findings suggest that in-house training might increase the knowledge of community pharmacists regarding hypertension management.

The change in pharmacists’ attitude, confidence and job satisfaction following participation in a novel hypertension support service

Objectives

To demonstrate how the confidence, attitude and job satisfaction of pharmacists who provide interventions and lifestyle support services to patients with hypertension are altered.

Methods

This study was a before-and-after study that used data from 50 pharmacists who participated in the Community Pharmacists Assist for Blood Pressure (COMPASS-BP) study, which was an interventional study that was conducted in Japan to evaluate the effects of lifestyle support services provided to hypertension patients. The pharmacists received 4 h of training before the study was initiated to learn how to quickly provide patients with guidance about diet and exercise and tobacco and alcohol consumption. During the interventional period, each pharmacist provided concise lifestyle guidance to 1–3 hypertension patients. The pharmacists met with the patients a total of 5 times. The parameters that were assessed were the pharmacists’ attitudes towards and confidence in their lifestyle support services, as well as their level of job satisfaction. We verified the scores of each parameter assessed before and after the study, as well as changes in the relationships among the different parameters.

Key findings

Significant increases from baseline to the end of the study were observed for Confidence (P &lt; 0.01), Job satisfaction, including ‘Knowledge’ (P &lt; 0.01), ‘Patient counselling management’ (P = 0.04) and ‘Sense of personal growth’ (P &lt; 0.01). Additionally, path analysis results revealed that after the study, the causal relationship between ‘Knowledge’ and ‘Attitude’ disappeared, and a new causal relationship appeared between ‘Patient counselling and management’ and ‘Attitude’.

Conclusions

Providing lifestyle guidance improved pharmacists’ confidence and attitude. Also, ‘Attitude’ tended to improve as the ‘Patient counselling and management’ score increased.

The degree of integration of non-dispensing pharmacists in primary care practice and the impact on health outcomes: A systematic review

BACKGROUND

A non-dispensing pharmacist conducts clinical pharmacy services aimed at optimizing patients individual pharmacotherapy. Embedding a non-dispensing pharmacist in primary care practice enables collaboration, probably enhancing patient care. The degree of integration of non-dispensing pharmacists into multidisciplinary health care teams varies strongly between settings. The degree of integration may be a determinant for its success.

OBJECTIVES

This study investigates how the degree of integration of a non-dispensing pharmacist impacts medication related health outcomes in primary care.

METHODS

In this literature review we searched two electronic databases and the reference list of published literature reviews for studies about clinical pharmacy services performed by non-dispensing pharmacists physically co-located in primary care practice. We assessed the degree of integration via key dimensions of integration based on the conceptual framework of Walshe and Smith. We included English language studies of any design that had a control group or baseline comparison published from 1966 to June 2016. Descriptive statistics were used to correlate the degree of integration to health outcomes. The analysis was stratified for disease-specific and patient-centered clinical pharmacy services.

RESULTS

Eighty-nine health outcomes in 60 comparative studies contributed to the analysis. The accumulated evidence from these studies shows no impact of the degree of integration of non-dispensing pharmacists on health outcomes. For disease specific clinical pharmacy services the percentage of improved health outcomes for none, partial and fully integrated NDPs is respectively 75%, 63% and 59%. For patient-centered clinical pharmacy services the percentage of improved health outcomes for none, partial and fully integrated NDPs is respectively 55%, 57% and 70%.

CONCLUSIONS

Full integration adds value to patient-centered clinical pharmacy services, but not to disease-specific clinical pharmacy services. To obtain maximum benefits of clinical pharmacy services for patients with multiple medications and comorbidities, full integration of non-dispensing pharmacists should be promoted.

What works for whom in pharmacist-led smoking cessation support: realist review

BACKGROUND

New models of primary care are needed to address funding and staffing pressures. We addressed the research question "what works for whom in what circumstances in relation to the role of community pharmacies in providing lifestyle interventions to support smoking cessation?"

METHODS

This is a realist review conducted according to RAMESES standards. We began with a sample of 103 papers included in a quantitative review of community pharmacy intervention trials identified through systematic searching of seven databases. We supplemented this with additional papers: studies that had been excluded from the quantitative review but which provided rigorous and relevant additional data for realist theorising; citation chaining (pursuing reference lists and Google Scholar forward tracking of key papers); the 'search similar citations' function on PubMed. After mapping what research questions had been addressed by these studies and how, we undertook a realist analysis to identify and refine candidate theories about context-mechanism-outcome configurations.

RESULTS

Our final sample consisted of 66 papers describing 74 studies (12 systematic reviews, 6 narrative reviews, 18 RCTs, 1 process detail of a RCT, 1 cost-effectiveness study, 12 evaluations of training, 10 surveys, 8 qualitative studies, 2 case studies, 2 business models, 1 development of complex intervention). Most studies had been undertaken in the field of pharmacy practice (pharmacists studying what pharmacists do) and demonstrated the success of pharmacist training in improving confidence, knowledge and (in many but not all studies) patient outcomes. Whilst a few empirical studies had applied psychological theories to account for behaviour change in pharmacists or people attempting to quit, we found no studies that had either developed or tested specific theoretical models to explore how pharmacists' behaviour may be affected by organisational context. Because of the nature of the empirical data, only a provisional realist analysis was possible, consisting of five mechanisms (pharmacist identity, pharmacist capability, pharmacist motivation and clinician confidence and public trust). We offer hypotheses about how these mechanisms might play out differently in different contexts to account for the success, failure or partial success of pharmacy-based smoking cessation efforts.

CONCLUSION

Smoking cessation support from community pharmacists and their staff has been extensively studied, but few policy-relevant conclusions are possible. We recommend that further research should avoid duplicating existing literature on individual behaviour change; seek to study the organisational and system context and how this may shape, enable and constrain pharmacists' extended role; and develop and test theory.

Role of pharmacist in cardiovascular disease-related health promotion and in hypertension and dyslipidemia management: a cross-sectional study in the State of Qatar

RATIONALE, AIMS AND OBJECTIVES

In Qatar, cardiovascular diseases (CVD) have recently become the leading cause of morbidity and mortality. Prevention, detection and management of CVD risk factors reduce CVD chance. The study objectives were to assess Qatar pharmacists' involvement in CVD health promotion, to identify the activities that they currently provide to patients with CVD risk factors, to describe their attitudes towards their involvement in CVD prevention and to assess their perceived barriers for provision of CVD prevention services

METHOD

We conducted a cross-sectional survey of community and ambulatory pharmacists in Qatar. Pharmacist characteristics, involvement in CVD-related activities along with their attitudes and perceived barriers were analysed using frequency distributions. Bivariate linear regression models were used to test for associations between CVD health promotion activity score and each variable. Variables with a P-value of 0.20 or less were included in the multivariate model.

RESULTS

A total of 141 pharmacists completed the survey (response rate 60%). More than 70% responded with rarely or never to 6 out of the 10 CVD health promotion activities. Eighty-four per cent and 68% always or often describe to patients the appropriate time to take antihypertensive medications and the common medication adverse effects, respectively. Yet, 50% rarely or never review the medication refill history or provide adherence interventions. Lack of CVD educational materials was the top perceived barrier (55%) in addition to lack of having private counselling area (44.6%), and lack of time (38.3%). Females and community pharmacists were more involved in CVD health promotion (P = 0.046 and P = 0.017, respectively) than their counterparts. Health promotion practice increased with increasing attitudes score and decreased with increased barriers score (P = 0.012 and P = 0.001).

CONCLUSION

The scope of pharmacy practice in CVD prevention is limited in Qatar. Efforts need to be exerted to increase pharmacists' involvement in CVD prevention.

[The pharmacist-physician collaboration for IPW: from physician's perspective]

Interprofessional work (IPW) is increasingly important in various settings including primary care, in which the role of pharmacists is particularly important. Many studies have shown that in cases of hypertension, diabetes, dyslipidemia, and metabolic syndrome, physician-pharmacist collaboration can improve medication adherence and help to identify drug-related problems. Some surveys and qualitative studies revealed barriers and key factors for effective physician-pharmacist collaboration, including trustworthiness and role clarification. In Japan, some cases of good collaborative work between pharmacists and physicians in hospitals and primary care settings have been reported. Still, community pharmacists in particular have difficulties collaborating with primary care doctors because they have insufficient medical information about patients, they feel hesitant about contacting physicians, and they usually communicate by phone or fax rather than face to face. Essential competencies for good interprofessional collaboration have been proposed by the Canadian Interprofessional Health Collaborative (CIHC): interprofessional communication; patient/client/family/community-centered care; role clarification; team functioning; collaborative leadership; and interprofessional conflict resolution. Our interprofessional education (IPE) team regularly offers educational programs to help health professionals learn interprofessional collaboration skills. We expect many pharmacists to learn those skills and actively to facilitate interprofessional collaboration.

Reduced dietary salt for the prevention of cardiovascular disease

BACKGROUND

This is an update of a Cochrane review that was first published in 2011 of the effects of reducing dietary salt intake, through advice to reduce salt intake or low-sodium salt substitution, on mortality and cardiovascular events.

OBJECTIVES

1. To assess the long-term effects of advice and salt substitution, aimed at reducing dietary salt, on mortality and cardiovascular morbidity.2. To investigate whether a reduction in blood pressure is an explanatory factor in the effect of such dietary interventions on mortality and cardiovascular outcomes.

SEARCH METHODS

We updated the searches of CENTRAL (2013, Issue 4), MEDLINE (OVID, 1946 to April week 3 2013), EMBASE (OVID, 1947 to 30 April 2013) and CINAHL (EBSCO, inception to 1 April 2013) and last ran these on 1 May 2013. We also checked the references of included studies and reviews. We applied no language restrictions.

SELECTION CRITERIA

Trials fulfilled the following criteria: (1) randomised, with follow-up of at least six months, (2) the intervention was reduced dietary salt (through advice to reduce salt intake or low-sodium salt substitution), (3) participants were adults and (4) mortality or cardiovascular morbidity data were available. Two review authors independently assessed whether studies met these criteria.

DATA COLLECTION AND ANALYSIS

A single author extracted data and assessed study validity, and a second author checked this. We contacted trial authors where possible to obtain missing information. We extracted events and calculated risk ratios (RRs) and 95% confidence intervals (CIs).

MAIN RESULTS

Eight studies met the inclusion criteria: three in normotensives (n = 3518) and five in hypertensives or mixed populations of normo- and hypertensives (n = 3766). End of trial follow-up ranged from six to 36 months and the longest observational follow-up (after trial end) was 12.7 years.The risk ratios (RR) for all-cause mortality in normotensives were imprecise and showed no evidence of reduction (end of trial RR 0.67, 95% confidence interval (CI) 0.40 to 1.12, 60 deaths; longest follow-up RR 0.90, 95% CI 0.58 to 1.40, 79 deaths n=3518) or in hypertensives (end of trial RR 1.00, 95% CI 0.86 to 1.15, 565 deaths; longest follow-up RR 0.99, 95% CI 0.87 to 1.14, 674 deaths n=3085). There was weak evidence of benefit for cardiovascular mortality (hypertensives: end of trial RR 0.67, 95% CI 0.45 to 1.01, 106 events n=2656) and for cardiovascular events (hypertensives: end of trial RR 0.76, 95% CI 0.57 to 1.01, 194 events, four studies, n = 3397; normotensives: at longest follow-up RR 0.71, 95% CI 0.42 to 1.20, 200 events; hypertensives: RR 0.77, 95% CI 0.57 to 1.02, 192 events; pooled analysis of six trials RR 0.77, 95% CI 0.63 to 0.95, n = 5912). These findings were driven by one trial among retirement home residents that reduced salt intake in the kitchens of the homes, thereby not requiring individual behaviour change.Advice to reduce salt showed small reductions in systolic blood pressure (mean difference (MD) -1.15 mmHg, 95% CI -2.32 to 0.02 n=2079) and diastolic blood pressure (MD -0.80 mmHg, 95% CI -1.37 to -0.23 n=2079) in normotensives and greater reductions in systolic blood pressure in hypertensives (MD -4.14 mmHg, 95% CI -5.84 to -2.43 n=675), but no difference in diastolic blood pressure (MD -3.74 mmHg, 95% CI -8.41 to 0.93 n=675).Overall many of the trials failed to report sufficient detail to assess their potential risk of bias. Health-related quality of life was assessed in one trial in normotensives, which reported significant improvements in well-being but no data were presented.

AUTHORS' CONCLUSIONS

Despite collating more event data than previous systematic reviews of randomised controlled trials, there is insufficient power to confirm clinically important effects of dietary advice and salt substitution on cardiovascular mortality in normotensive or hypertensive populations. Our estimates of the clinical benefits from advice to reduce dietary salt are imprecise, but are larger than would be predicted from the small blood pressure reductions achieved. Further well-powered studies would be needed to obtain more precise estimates. Our findings do not support individual dietary advice as a means of restricting salt intake. It is possible that alternative strategies that do not require individual behaviour change may be effective and merit further trials.

Interventions for enhancing medication adherence

BACKGROUND

People who are prescribed self administered medications typically take only about half their prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications.

OBJECTIVES

The primary objective of this review is to assess the effects of interventions intended to enhance patient adherence to prescribed medications for medical conditions, on both medication adherence and clinical outcomes.

SEARCH METHODS

We updated searches of The Cochrane Library, including CENTRAL (via http://onlinelibrary.wiley.com/cochranelibrary/search/), MEDLINE, EMBASE, PsycINFO (all via Ovid), CINAHL (via EBSCO), and Sociological Abstracts (via ProQuest) on 11 January 2013 with no language restriction. We also reviewed bibliographies in articles on patient adherence, and contacted authors of relevant original and review articles.

SELECTION CRITERIA

We included unconfounded RCTs of interventions to improve adherence with prescribed medications, measuring both medication adherence and clinical outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive findings at earlier time points.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted all data and a third author resolved disagreements. The studies differed widely according to medical condition, patient population, intervention, measures of adherence, and clinical outcomes. Pooling results according to one of these characteristics still leaves highly heterogeneous groups, and we could not justify meta-analysis. Instead, we conducted a qualitative analysis with a focus on the RCTs with the lowest risk of bias for study design and the primary clinical outcome.

MAIN RESULTS

The present update included 109 new RCTs published since the previous update in January 2007, bringing the total number of RCTs to 182; we found five RCTs from the previous update to be ineligible and excluded them. Studies were heterogeneous for patients, medical problems, treatment regimens, adherence interventions, and adherence and clinical outcome measurements, and most had high risk of bias. The main changes in comparison with the previous update include that we now: 1) report a lack of convincing evidence also specifically among the studies with the lowest risk of bias; 2) do not try to classify studies according to intervention type any more, due to the large heterogeneity; 3) make our database available for collaboration on sub-analyses, in acknowledgement of the need to make collective advancement in this difficult field of research. Of all 182 RCTs, 17 had the lowest risk of bias for study design features and their primary clinical outcome, 11 from the present update and six from the previous update. The RCTs at lowest risk of bias generally involved complex interventions with multiple components, trying to overcome barriers to adherence by means of tailored ongoing support from allied health professionals such as pharmacists, who often delivered intense education, counseling (including motivational interviewing or cognitive behavioral therapy by professionals) or daily treatment support (or both), and sometimes additional support from family or peers. Only five of these RCTs reported improvements in both adherence and clinical outcomes, and no common intervention characteristics were apparent. Even the most effective interventions did not lead to large improvements in adherence or clinical outcomes.

AUTHORS' CONCLUSIONS

Across the body of evidence, effects were inconsistent from study to study, and only a minority of lowest risk of bias RCTs improved both adherence and clinical outcomes. Current methods of improving medication adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. The research in this field needs advances, including improved design of feasible long-term interventions, objective adherence measures, and sufficient study power to detect improvements in patient-important clinical outcomes. By making our comprehensive database available for sharing we hope to contribute to achieving these advances.

Assessment of pharmacist-led patient counseling in randomized controlled trials: a systematic review

Background Pharmacists' counseling has improved health-related outcomes in many acute and chronic conditions. Several studies have shown how pharmacists have been contributing to reduce morbidity and mortality related to drug-therapy (MMRDT). However, there still is a lack of reviews that assemble evidence-based clinical pharmacists' counseling. Equally, there is also a need to understand structure characteristics, processes and technical contents of these clinical services. Aim of the review To review the structure, processes and technical contents of pharmacist counseling or education reported in randomized controlled trials (RCT) that had positive health-related outcomes. Methods We performed a systematic search in specialized databases to identify RCT published between 1990 and 2013 that have evaluated pharmacists' counseling or educational interventions to patients. Methodological quality of the trials was assessed using the Jadad scale. Pharmacists' interventions with positive clinical outcomes (p < 0.05) were evaluated according to patients' characteristics, setting and timing of intervention, reported written and verbal counseling. Results 753 studies were found and 101 RCT matched inclusion criteria. Most of the included RCTs showed a Jadad score between two (37 studies) and three (32 studies). Pharmacists were more likely to provide counseling at ambulatories (60 %) and hospital discharge (25 %); on the other hand pharmacists intervention were less likely to happen when dispensing a medication. Teaching back and explanations about the drug therapy purposes and precautions related to its use were often reported in RCT, whereas few studies used reminder charts, diaries, group or electronic counseling. Most of studies reported the provision of a printed material (letter, leaflet or medication record card), regarding accessible contents and cultural-concerned informations about drug therapy and disease. Conclusion Pharmacist counseling is an intervention directed to patients' health-related needs that improve inter-professional and inter-institutional communication, by collaborating to integrate health services. In spite of reducing MMRDT, we found that pharmacists' counseling reported in RCT should be better explored and described in details, hence collaborating to improve medication-counseling practice among other countries and settings.

Team-based care and improved blood pressure control: a community guide systematic review

CONTEXT

Uncontrolled hypertension remains a widely prevalent cardiovascular risk factor in the U.S. team-based care, established by adding new staff or changing the roles of existing staff such as nurses and pharmacists to work with a primary care provider and the patient. Team-based care has the potential to improve the quality of hypertension management. The goal of this Community Guide systematic review was to examine the effectiveness of team-based care in improving blood pressure (BP) outcomes.

EVIDENCE ACQUISITION

An existing systematic review (search period, January 1980-July 2003) assessing team-based care for BP control was supplemented with a Community Guide update (January 2003-May 2012). For the Community Guide update, two reviewers independently abstracted data and assessed quality of eligible studies.

EVIDENCE SYNTHESIS

Twenty-eight studies in the prior review (1980-2003) and an additional 52 studies from the Community Guide update (2003-2012) qualified for inclusion. Results from both bodies of evidence suggest that team-based care is effective in improving BP outcomes. From the update, the proportion of patients with controlled BP improved (median increase=12 percentage points); systolic BP decreased (median reduction=5.4 mmHg); and diastolic BP also decreased (median reduction=1.8 mmHg).

CONCLUSIONS

Team-based care increased the proportion of people with controlled BP and reduced both systolic and diastolic BP, especially when pharmacists and nurses were part of the team. Findings are applicable to a range of U.S. settings and population groups. Implementation of this multidisciplinary approach will require health system-level organizational changes and could be an important element of the medical home.

Dietary approaches to hypertension: a call to pharmacists to promote lifestyle changes

OBJECTIVES

To describe guideline updates regarding a dietary approach to preventing or treating hypertension and to encourage pharmacists to provide education to patients on the Dietary Approaches to Stop Hypertension (DASH) diet and reducing dietary sodium intake.

DATA SOURCES

Abstracts and published articles identified by searching Medline (January 2001 to July 2011) and International Pharmaceutical Abstracts (January 2001 to July 2011) using the terms hypertension, cardiovascular risk, risk reduction behavior, health behavior, community pharmacy services, counseling, diet, and sodium-restricted diet, as well as reports from the Institute of Medicine and Dietary Guidelines for Americans 2010.

DATA SYNTHESIS

In the Dietary Guidelines for Americans 2010, the recommended daily dietary sodium intakes for individuals with hypertension, chronic kidney disease, and diabetes was reduced to less than 1,500 mg per day. All other healthy individuals are recommended to achieve dietary sodium intakes of less than 2,300 mg per day. Americans are consuming excessive amounts of dietary sodium in the form of processed foods, which poses a barrier to blood pressure control. Pharmacists should recommend the DASH diet as a way to reduce intake of dietary sodium and use available nutrition resources found on the ChooseMyPlate.gov and Food and Drug Administration websites. Pharmacists should integrate approaches using behavioral and motivational strategies to provide education that is culturally sensitive and appeals to individuals with marginal health literacy.

CONCLUSION

Community and ambulatory practice pharmacists, as well as collaborative practice models between pharmacists and physicians, should optimize medication management and incorporate lifestyle interventions that reduce dietary sodium intake as part of a comprehensive approach to improve hypertension outcomes.

Impact of a clinical pharmacist on a cardiovascular surrogate endpoint: a pilot study

Utilizing a multidisciplinary approach to management of patients with certain chronic cardiovascular diseases (CVD) has been shown to improve treatment outcomes. The role of clinical pharmacists in comprehensive outpatient CVD management has not been evaluated.

OBJECTIVE

The objective of this pilot study was to evaluate the impact of a clinical pharmacist added to cardiologist care on blood pressure (BP), a key surrogate marker of CVD, in outpatients with CVD compared to cardiologist care alone.

METHODS

A retrospective, matched-control study was conducted in patients established in a cardiovascular clinic. The intervention was referral to a pharmacist clinic; control was usual care from the cardiologist. The surrogate marker evaluated was the change in BP.

RESULTS

Patients in the pharmacist-intervention (n=57) experienced significant reductions in diastolic BP (-2.6 mmHg, p=0.05) and non-significant reductions in systolic BP (-4.3 mmHg, p=0.16) compared to baseline, whereas patients in the control group experienced non-significant increases in both systolic and diastolic BP (+1.6/+0.7 mmHg, p=NS). Similarly, there were significant reductions in diastolic BP and non-significant reductions in systolic BP for the intervention group when compared to controls (difference 3.3 mmHg, p=0.04 and 5.9 mmHg, p=0.1, respectively). Lastly, the proportion of patients categorized as having Stage 2 BP was significantly reduced in the intervention group (p=0.02), but not in the controls (p=0.5).

CONCLUSIONS

The multidisciplinary model of care that included a clinical pharmacist reduced BP more than usual care by a cardiologist alone. This benefit was demonstrated in complex patients with CVD who were already receiving specialized care. The impact of this model on clinical outcomes requires further evaluation and should be a high priority given the burden of CVD in the population.

Improving blood pressure control through a clinical pharmacist outreach program in patients with diabetes mellitus in 2 high-performing health systems: the adherence and intensification of medications cluster randomized, controlled pragmatic trial

BACKGROUND

Even in high-performing health systems, some patients with diabetes mellitus have poor blood pressure (BP) control because of poor medication adherence and lack of medication intensification. We examined whether the Adherence and Intensification of Medications intervention, a pharmacist-led intervention combining elements found in efficacy studies to lower BP, improved BP among patients with diabetes mellitus with persistent hypertension and poor refill adherence or insufficient medication intensification in 2 high-performing health systems.

METHODS AND RESULTS

We conducted a prospective, multisite cluster randomized pragmatic trial with randomization of 16 primary care teams at 5 medical centers (3 Veterans Affairs and 2 Kaiser Permanente) to the Adherence and Intensification of Medications intervention or usual care. The primary outcome was relative change in systolic BP (SBP), comparing 1797 intervention with 2303 control team patients, from 6 months preceding to 6 months after the 14-month intervention period. We examined shorter-term changes in SBP as a secondary outcome. The mean SBP decrease from 6 months before to 6 months after the intervention period was ≈9 mm Hg in both arms. Mean SBPs of eligible intervention patients were 2.4 mm Hg lower (95% CI: -3.4 to -1.5; P<0.001) immediately after the intervention than those achieved by control patients.

CONCLUSIONS

The Adherence and Intensification of Medications program more rapidly lowered SBPs among intervention patients, but usual-care patients achieved equally low SBP levels by 6 months after the intervention period. These findings show the importance of evaluating in different real-life clinical settings programs found in efficacy trials to be effective before urging their widespread adoption in all settings.

[An occupational physician-pharmacist cooperative management for hypertension by the use of educational letters and posters]

OBJECTIVES

To provide an occupational physician-pharmacist cooperative management for hypertension, we aimed to improve blood pressure (BP) control for workers with high-normal BP or hypertension.

METHOD

Health checkups were performed from May 2005 to May 2008 for male professional grooms and exercise riders aged 20-69 years working at Miho Training Center, the largest racing-horse training facility in Japan. An occupational physician-pharmacist cooperative hypertension management was performed from Jan 2007 to Mar 2008, including the use of posters at the work site and letters to employers and the subjects who were diagnosed as having high-normal BP (office systolic/diastolic BPs 130-139 and/or 85-89 mmHg) or hypertension (≥ 140 and/or 90 mmHg) twice during 2005-2006 examinations. The observational study examined BP measurements before and after the hypertension management.

RESULTS

We analyzed 232 participants in the 2008 Nov examination with had high-normal BP or hypertension in both of 2005 and 2006 Nov examinations. Office systolic and diastolic BP decreased after the hypertension management by the use of educational letters and posters (-3.1 mmHg; p<0.001, -1.5 mmHg; p=0.02). The prevalence of workers with high-normal BP and hypertension also decreased after those activities (-15% and -7%; p<0.001). The subjects who started or continued the antihypertensive medication were more likely to show reductions in office BP and body mass index than those who received no treatment.

CONCLUSIONS

An occupational physician-pharmacist cooperated hypertension management by the use of educational letters and posters may improve BP control for subjects with high-normal BP or hypertension.
