Pharmaceutical care in hypertensive patients: A systematic literature review

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.

Effectiveness of a pharmacist-led educational intervention on health outcomes in hypertension management at community pharmacies in Nigeria: A two-arm parallel single-blind randomized controlled trial

AIMS

This study determined the impact of a pharmacist-led educational intervention on the health outcomes of hypertensive patients in community pharmacies.

METHODS

A 2-arm parallel single-blind randomized trial design was adopted among hypertensive patients in 4 pharmacies in Abuja and Lokoja, Nigeria. A pharmacist-led educational intervention was provided to the patients in the intervention group. The study outcomes, namely changes in adherence to medication, quality of life and cost of medication were measured using MARS-10, SF-12 and official price list, respectively. Independent and paired-sample t-tests were conducted on the data.

RESULTS

A total of 128 patients participated in the study. All of them completed the study and were included in the analysis: 70 in the control arm and 58 in the intervention arm. There was a significant improvement in components of Behaviour (2.57 vs. 2.98), Attitude (2.59 vs. 3.14) and Negative attitude (1.62 vs. 1.92). There was a better improvement in adherence in the intervention arm: 8.05 ± 1.32 vs. 6.55 ± 2.24; t = -4.65, P = .0001. There were no changes in the respondents' health status after intervention in both groups (P < .05). There was a weak inverse association between the physical health component and mental health component: R = -0.2, P = .04 and a positive association with overall adherence (R = 0.26, P = .004) in the intervention group, in whom the monthly cost of treatment decreased from N2233.1 to N2068.4.

CONCLUSION

Community pharmacy educational intervention improves health outcomes, particularly with adherence among patients with hypertension. Health-related quality of life of the patients improved, but the physical health component was better than that of the mental health component.

[Adherence, barriers, and facilitators for the treatment of systemic arterial hypertension: rapid review of evidenceAdhesión, obstáculos y elementos facilitadores en relación con el tratamiento de la hipertensión: revisión rápida de la evidencia]

Objective

To identify strategies to increase adherence to systemic arterial hypertension (SAH) treatment and describe the barriers and facilitators for implementing these strategies in primary health care (PHC).

Method

A rapid evidence review was performed. We included systematic reviews with or without meta-analyses, published in English, Spanish or Portuguese, covering adults (age 18 to ≤ 60 years) with SAH followed in the PHC. Searches were performed in nine databases in December 2020 and updated in April 2022. The systematic reviews were assessed for methodological quality using the AMSTAR 2 tool.

Results

Fourteen systematic reviews on treatment adherence strategies and three on barriers and facilitators for implementation were included. Regarding methodological quality, one systematic review was classified as moderate, four as low, and the others as critically low. Four strategies were identified as options for health policies: actions performed by pharmacists; actions performed by non-pharmaceutical health professionals; self-monitoring, use of mobile apps, and text messages; and subsidies for the purchase of medicines. Low digital literacy, limited access to the internet, work process and incipient training were barriers for professionals. The users' educational and health literacy levels, accessibility to health services and good relationships with professionals were facilitators.

Conclusions

Positive effects of strategies related to pharmaceutical care, self-monitoring, and the use of cell phone applications and text messages were identified to increase adherence to the treatment of SAH in the context of PHC. However, for implementation purposes, it is necessary to consider barriers and facilitators, in addition to the methodological limitations of the analyzed systematic reviews.

Development of coupled patient care experience courses to enhance patient care skills in the ambulatory and acute care settings

BACKGROUND AND PURPOSE

Providing opportunities to allow pharmacy students to apply clinical skills is essential to ensure that they are comfortable and competent to perform these skills during advanced pharmacy practice experiences (APPEs) and in practice. We describe unique coupled courses that require students to apply clinical skills during real patient encounters and simulation activities in the ambulatory and acute care setting to ensure that they are ready for APPEs.

EDUCATIONAL ACTIVITY AND SETTING

New required courses were developed at West Virginia University School of Pharmacy that focused on teaching and reinforcing patient care skills in the ambulatory and acute care settings. Both courses were designed to provide students with multiple opportunities to offer supervised patient care and to become more comfortable and confident in their patient care skills.

FINDINGS

The coupled courses were well-received by students. Feedback indicated that students felt more comfortable in these patient care settings and in performing patient care activities as a result of these courses.

SUMMARY

These coupled courses offered multiple opportunities for students to practice patient care skills and gain valuable experience participating in activities that increased their confidence and competence at being integral members of the healthcare team. The interactions with real patients, simulated patient scenarios, standardized patients, and other members of the healthcare team helped students advance communication skills, clinical skills, and ability to identify and resolve medication-related problems in preparation for APPEs.

Effects of lifestyle advice provided by pharmacists on blood pressure: The COMmunity Pharmacists ASSist for Blood Pressure (COMPASS-BP) randomized trial

The COMmunity Pharamcists ASSist for Blood Pressure (COMPASS-BP) study aimed to assess the effectiveness of lifestyle support programs administered in community pharmacies on hypertension control. This open-label, two-armed parallel group, cluster-randomized controlled trial included 73 pharmacies (clusters) in Japan randomized to a control or intervention group. Eligible hypertensive patients (n = 125), aged 20-75 years, received the intervention (n = 64) or the control treatment (n = 61), as dictated by their pharmacy randomization. Patients in the intervention group received brochures and healthy lifestyle advice from pharmacists using motivational interviewing methods during pharmacy visits over a 12-week period, with their usual pharmacy care. Conversely, the control group just received usual care. The main outcome measure was a change in morning systolic blood pressure (SBP) from baseline to week 12. The intervention group exhibited a decrease in morning SBP that was 6.0 mmHg greater than that of the control group (95% confidence interval [CI]: -11.0 to -0.9, p = 0.021). In a mixed-effect model for repeated measures analysis, the intergroup difference in morning SBP decrease was -4.5 mmHg (95% CI: -8.5 to -0.6, p = 0.024). Our findings indicate that implementation of a lifestyle advice program in pharmacies is feasible and may lead to reduced blood pressure.

Randomized controlled trials covering pharmaceutical care and medicines management: A systematic review of literature

OBJECTIVE

To review the effects of pharmaceutical care on hospitalizations, mortality and clinical outcomes in patients.

METHODS

Systematic searches were conducted in MEDLINE, EMBASE and International Pharmaceutical Abstracts (IPA) databases to identify studies that were published between 2004 and January 2017. Studies included in this review were randomized controlled trials (RCTs) that spanned across both community and hospital settings. Using strict inclusion/exclusion criteria studies were included if they reported level 1 or 2 outcomes in the hierarchy of outcome measure i.e. clinical and surrogate outcomes (e.g. blood pressure (BP) control, blood glucose level, cholesterol BMI). Each study was assessed for quality using the Jadad scoring system.

RESULTS

Fifty-four RCTs were included in the present review. Forty-six of these studies ranked high quality according to the Jadad scoring system. Studies were categorized into their general condition groups. Interventions in patients with diabetes, depression, respiratory disorders, cardiovascular disorders, epilepsy, osteoporosis, and interventions in older adults were identified. In the majority of studies pharmaceutical care was found to lead to significant improvements in clinical outcomes and/or hospitalizations when compared to the non-intervention group. Some conditions had a large number of RCTs, for example for cardiovascular conditions and in diabetes. Statistically significant improvements were seen in the majority of the studies included for both of these conditions, with studies indicating positive clinical outcomes and/or hospitalizations rates. Within the cardiovascular condition, a subset of studies, focusing on cardiac heart failure and coronary heart disease, had more mixed results. In other conditions the number of RCTs conducted was small and the evidence did not show improvements after pharmaceutical care, i.e. in depression, osteoporosis, and epilepsy. The majority of interventions were face to face interactions with patients, whilst a smaller number were conducted via the telephone and one via a web-based system. Patient education was a key component of most interventions, either verbal and/or written. Longitudinal data, post intervention cessation, was not collected in the majority of cases.

CONCLUSIONS

RCTs conducted to evaluate pharmaceutical care appear to be effective in improving patient short-term outcomes for a number of conditions including diabetes and cardiovascular conditions, however, other conditions such as depression are less well researched. Future research should attempt to evaluate the conditions where there is a lack of data, whether the positive effects of pharmaceutical care persist in patient populations after the interventions cease and what the long-term clinical outcomes would be of continued pharmaceutical care.

Can we document the practice of dispensing? A systematic review

WHAT IS KNOWN

Documentation is a process indicator utilized to evaluate quality clinical pharmacist services. In this framework, documentation of dispensing, besides supporting patient care, allows evaluation of the impact of counselling.

OBJECTIVE

To identify and assess studies of documentation by pharmacists in the dispensing process.

METHOD

A systematic review was carried out according to the following steps: (i) identification of studies in the following databases: PubMed/Medline, Web of Science, Scopus and Lilacs, using the descriptors 'counselling', 'dispensing', 'community pharmacy services', 'pharmacies' and 'pharmacists' in different combinations; (ii) evaluation of studies, in which the title, abstract and full text of the studies, and the evaluation of the methodological quality of the selected studies were analysed.

RESULTS

In total, 26 articles met the specific criteria. Few studies addressed documentation as part of the dispensing working process (3), and 16 articles reported documentation using non-electronic systems. The main variables documented were patient information, drug therapy problems and clinical interventions. Furthermore, 20 studies showed the effects of documentation in the dispensing process and 23 studies included statistical evidence. Eight articles met between 42% and 75% of the 28 items recommended by the STROBE initiative, and two articles met approximately 60% of the 36 items recommended by the CONSORT initiative.

WHAT IS NEW AND CONCLUSION

Few studies address documentation as part of the dispensing working process. Thus, researchers should be concerned with standardizing documentation and implementing more robust designs and multicenter studies.

Impact of Pharmaceutical Care Interventions on Health-Related Quality-of-Life Outcomes: A Systematic Review and Meta-analysis

OBJECTIVE

To evaluate the impact of pharmaceutical care (PC) interventions on health-related quality of life (HRQoL) and determine sensitivity of HRQoL measures to PC services.

DATA SOURCES

MEDLINE, EMBASE, International Pharmaceutical Abstracts, PubMed, Global Health, PsychINFO, CINAHL, and Web of Science (January 2005 to September 2015) were searched.

STUDY SELECTION AND DATA EXTRACTION

Original English-language articles were included if PC impact on HRQoL was evaluated and reported using validated HRQoL measures.

DATA SYNTHESIS

A total of 31 randomized controlled trials, 9 nonrandomized studies with comparison groups, and 8 before-after studies were included. PC interventions resulted in significant improvement in 1 domain and ≥3 domains of HRQoL measures in 66.7% and 27.1% of the studies, respectively. There was a significant improvement in at least 1 domain in 18 of 32 studies using generic and 16 of 21 studies using disease-specific measures. When the Short Form 36 Items Health Survey (SF-36) measure was used, PC interventions had a moderate impact on social functioning (standardized mean difference [SMD] = 0.59; 95% CI = 0.14, 1.04), general health (SMD = 0.36; 95% CI = 0.12, 0.59), and physical functioning (SMD = 0.30; 95% CI = 0.11, 0.48). The pooled data on heart failure-specific (SMD = -0.17; 95% CI = -0.43, 0.09), asthma-specific (SMD = 0.17; 95% CI = -0.03, 0.36), and chronic obstructive pulmonary disease-specific (SMD = -0.09; 95% CI = -0.37, 0.19) measures indicated no significant impact of PC on HRQoL.

CONCLUSIONS

PC interventions can significantly improve at least 1 domain of HRQoL. Existing measures may have minimal to moderate sensitivity to PC interventions, with evidence pointing more toward social functioning, general health, and physical functioning of the SF-36 measure. However, evidence generated from current non-PC-specific HRQoL measures is insufficient to judge the impact of PC interventions on HRQoL. The development of a suitable HRQoL measure for PC interventions may help generate better evidence for the contribution of pharmacist services to improving HRQoL.

Cardiovascular risk rate in hypertensive patients attended in primary health care units: the influence of pharmaceutical care

Cardiovascular complications are relevant due to their frequency and severity on the hypertension scenario. Studies refer Pharmaceutical Care (PC) as capable of decreasing cardiovascular risk rate (%CVR) on hypertensive patients. This study aimed to investigate, through a randomized clinical assay, the influence of PC service on the %CVR of hypertensive patients assisted in a health primary care unit from Fortaleza-Ceará. Two study groups were formed: i. Intervention Group (IG), which received orientation about taking medicines, actions aiming to prevent/solve medicine interactions and adverse effects and non-pharmacological interventions for 9 months and, ii. Control Group (CG), which received traditional assistance of the unit and was monitored during the same period. It was observed a statistically significant reduction on %CVR (10.76 to 7.86; p=0.04) and systolic blood pressure levels (SBP) (137.69 to 131.54; p<0.01) in the IG, while, in the CG, there was no significant alteration. 151 Drug Related Problem (DRP) were identified and it was realized 124 pharmaceutical interventions, with 89.2% of them resulting on solution/prevention of the problem. Our findings indicated that the inclusion of the PC service in the hypertensive health assistance was more effective at the %CVR and the SBP reduction in comparison to the traditional assistance offered.

Investigation on barriers to pharmaceutical care in community pharmacies: a structural equation model

OBJECTIVE

The concept of pharmaceutical care (PhC) has been popular in pharmacy during past decades. However, in some countries, including Iran, it does not seem to mature.

AIM OF THE STUDY

To identify and prioritize barriers to the provision of PhC in Iranian community pharmacies, based on the perceptions of community pharmacists in Tehran.

METHOD

Between August and November 2013, a cross-sectional descriptive study was performed using an anonymous questionnaire asking the pharmacists' perceptions on the implementation of PhC. Of the 2000 invited community pharmacists, 505 pharmacists responded. A descriptive analysis, was conducted, and the data were also analyzed through structural equation modeling.

MAIN OUTCOME MEASURE

Priorities of barriers to the implementation of PhC in Iran.

RESULTS

Five major dimensions included in the survey instrument were confirmed by confirmatory factor analysis. According to the model developed based on pharmacists' opinions, lack of pharmacists' skills and lack of appropriate regulation and environment are the two most important barriers of the provision of PhC, and the least important is lack of resources.

CONCLUSION

The results show that the main barriers to PhC in Iran are the lack of skills and of appropriate regulation and environment. These main barriers are different from those mentioned in studies conducted in other countries.

Pharmaceutical care in transplant patients in a university hospital: pharmaceutical interventions

A descriptive and prospective study was conducted on the pharmaceutical care in the post-transplant outpatient clinic of Hospital Universitario Walter Cantidio of Universidade Federal do Ceará (HUWC/UFC), in Fortaleza- Ceará in the period of April to October of 2011. The aim of the present study was to describe the pharmaceutical interventions performed in a Pharmaceutical Care service structured in the liver and kidney transplant outpatient clinic of an academic hospital. The Pharmaceutical interventions (PI) were classified according to Sabater et al.(2005), with significance based on Riba et al.(2000) and the Negative Outcomes associated with Medication (NOM) established at the Third Consensus of Granada. Statistical analyses were performed using the Epi Info v.3.5.1 program and hypothesis tests were done with the SigmaPlot v.10.0 program. A chi-squared (X²) test was utilized for statistical analysis of the sample. A total of 97 patients were followed, where 54 problems related to medications were identified and 139 PI performed. The main PI were in education of the patient about treatment (n=111; 80%) (p<0.05), while the significance of all interventions were appropriate, where 83.4% (n=116) of PI performed in the study period were shown to be "significant" (p<0.05). Through pharmaceutical care, the pharmacist is capable of monitoring the pharmacotherapeutic treatment and intervening when necessary, while being part of the multiprofessional team caring for the transplant patient.

Pharmaceutical Care for hypertensive patients provided within the Family Health Strategy in Goiânia, Goiás, Brazil

The aim of Pharmaceutical Care programs is to improve patients' quality of life, and such programs are particularly effective in the case of chronic diseases such as hypertension. The objective of this longitudinal study was to analyze a Pharmaceutical Care model for hypertensive patients receiving care within the Family Health Strategy (FHS). All patients were being seen by an FHS team affiliated to a primary healthcare unit in Goiânia, Goiás, Brazil. Fourteen patients participated in the study, with each patient receiving six home visits during the Pharmaceutical Care. Overall, 142 drug-related problems were reported, the most common concerning the ineffectiveness of treatment (33.8%). A total of 135 pharmaceutical interventions were performed, 92.6% of which involved pharmacist-patient communication, with 48.8% of these interventions being implemented. Cardiovascular risk decreased in three patients and remained unchanged in nine. In hypertensive patients with diabetes, fasting glucose levels were reduced in six out of nine cases. The Pharmaceutical Care model proposed here was effective in detecting drug-related problems and in proposing interventions to resolve or prevent these problems. Consequently, this may have contributed towards improving clinical parameters, such as fasting glucose levels and cardiovascular risk in hypertensive patients receiving care within the FHS.
