The 2017 American College of Cardiology/American Heart Association hypertension guideline and opportunities for community pharmacists

Utilization of telepharmacy in the management of hypertension

BACKGROUND

Deaths due to cardiovascular diseases is on the rise, with hypertension as its most important risk factor. Effective management of hypertension, however, remains a challenge. Globally, only one in five adults with hypertension have it under control. The situation is worse in sub-Saharan Africa where hypertension prevalence is highest. Telepharmacy presents a great opportunity to enhance the way we address hypertension management.

OBJECTIVES

This study sought to determine the effectiveness of pharmaceutical care interventions implemented through telepharmacy on medication adherence, practice of therapeutic lifestyles and overall blood pressure control among patients with hypertension.

METHODS

This was a randomized control trial conducted among individuals with hypertension recruited from two Ghanaian hospitals from May 2022 to December 2022. Patients with confirmed diagnosis of hypertension were recruited and assigned into a control or intervention group. Both groups were followed for six months with the intervention group receiving telepharmacy services in addition to standard clinical care. Outcome measures included changes in blood pressure, medication adherence, lifestyle modifications, identification and resolution of pharmaceutical care issues.

RESULTS

One hundred and eighteen (118) patients with hypertension were involved in the study. There was a statistically significant reduction in mean blood pressures for the intervention group after six months (Systolic-148.1 + 23.6, to 134.8 + 13.7, Diastolic- 85.8 + 9.8, to 79.5 + 8.7) (p < 0.05). The proportion of patients with adequately controlled blood pressure increased from 39.0% to 66.1%. There was also an increase in the mean adherence score (p < 0.05). The number of participants who adopted lifestyle modifications such as reducing salt consumption (89.5%) and exercising (77.2%) increased. The majority (87%) of all pharmaceutical care issues were identified and resolved over the six-month period.

CONCLUSION

Telepharmacy service provided via phone calls was effective in improving the control of blood pressure. It also promoted the practice of therapeutic lifestyle modifications, medication adherence and identification of pharmaceutical care issues among patients with hypertension.

Professionals' and Patients' Perspectives on Criteria for Referring Hypertensive Patients to Comprehensive Medication Management Services in Public Primary Health Care

Patient prioritization in comprehensive medication management services allows coordinating care and guiding patients according to their clinical profile and their medication use. The aim of the study is to identify and describe factors that indicate the need for comprehensive medication management services among primary care hypertension patients within a public health system from the perspective of patients, pharmacists, nurses and physicians. A qualitative study was carried out with interviews with nurses, pharmacists and physicians (n = 20), and two focus groups with hypertensive patients (n = 12) at primary health care facilities and a public outdoor fitness area between January and February 2019 in Brazil. All interviews were transcribed and analyzed using the Atlas.ti^® software. The data analysis revealed the following factors indicative of the need to refer hypertension patients to a pharmacist: lifestyle habits, comorbidities, health care utilization and medication use. The issues identified and the information obtained from the qualitative research and compared with literature studies reviewed allowed defining dimensions that should be considered as an aid in the selection of uncontrolled hypertensive patients for comprehensive medication management services.

Pregnancy Induced Hypertension and Uric Acid Levels among Pregnant Women Attending Ruhengeri Referral Hospital, in Rwanda

Background:

Pregnancy Induced Hypertension (PIH) is a common burden during pregnancy usually associoted with adverse maternal and paternal outcomes. The uric acid serum level was identified as an important biochemical marker which can predict preeclampsia, a type of PIH. This study was conducted to evaluate the effects of serum uric acid levels in association with blood pressure among pregnant women attending Ruhengeri Referral Hospital.

Methodology:

A cross-sectional study was designed and 80 pregnant women in different gestation trimesters participated in the study. Data was collected from September to October 2018. Digital sphygmomanometer was used to test blood pressures for participants. Blood samples were collected in red top tubes and centrifuged to obtain serum for uric acid levels. Using Humastar 80, uric acid levels were measured for each participant. Data was analysed using Statistical Package for Social Sciences (SPSS) version 23.0. Bivariate correlation was used to analyse the relationship between uric acid levels and participants’ blood pressure.

Results:

The median age was 27 in interquartile 23-31 ranging from 19 to 39 years. 58.75% of participants were in their 1^st trimester, followed by 21.25% in the 2^nd trimester and 20% in the 3^rd trimester. The prevalence of hypertension was 11.3% (7.5% for stage 1 and 3.8% for stage 2). Hyperuricemia was found in 15% of the participants. The mean of uric acid level was 7.12 ±1.86 mg/dl in the hypertensive group and 4.49 ±1.22 mg/dl in the non-hypertensive group. The study revealed a strong positive correlation between uric acid levels and systolic/diastolic blood pressure.

Conclusion:

High prevalence of hypertension among pregnant women was revealed. The association of hypertension and hyperuricemia was recorded with a strong correlation between blood pressures and serum uric acid levels. Examination of Uric acid levels among pregnant women should be routinely performed for early identification and management of hypertension.

Diagnostic performance of clinic and home blood pressure measurements compared with ambulatory blood pressure: a systematic review and meta-analysis

BACKGROUND

Clinic blood pressure measurement (CBPM) is currently the most commonly used form of screening for hypertension, however it might have a problem detecting white coat hypertension (WCHT) and masked hypertension (MHT). Home blood pressure measurement (HBPM) may be an alternative, but its diagnostic performance is inconclusive relative to CBPM. Therefore, this systematic review aimed to estimate the performance of CBPM and HBPM compared with ambulatory blood pressure measurement(ABPM) and to pool prevalence of WCHT and MHT.

METHODS

Medline, Scopus, Cochrane Central Register of Controlled Trials and WHO's International Clinical Trials Registry Platform databases were searched up to 23rd January 2020. Studies having diagnostic tests as CBPM or HBPM with reference standard as ABPM, reporting sensitivity and specificity of both tests and/or proportion of WCHT or MHT were eligible. Diagnostic performance of CBPM and HBPM were pooled using bivariate mixed-effect regression model. Random effect model was applied to pool prevalence of WCHT and MHT.

RESULTS

Fifty-eight studies were eligible. Pooled sensitivity, specificity, and diagnostic odds ratio (DOR) of CBPM, when using 24-h ABPM as the reference standard, were 74% (95% CI: 65-82%), 79% (95% CI: 69%, 87%), and 11.11 (95% CI: 6.82, 14.20), respectively. Pooled prevalence of WCHT and MHT were 0.24 (95% CI 0.19, 0.29) and 0.29 (95% CI 0.20, 0.38). Pooled sensitivity, specificity, and DOR of HBPM were 71% (95% CI 61%, 80%), 82% (95% CI 77%, 87%), and 11.60 (95% CI 8.98, 15.13), respectively.

CONCLUSIONS

Diagnostic performances of HBPM were slightly higher than CBPM. However, the prevalence of MHT was high in negative CBPM and some persons with normal HBPM had elevated BP from 24-h ABPM. Therefore, ABPM is still necessary for confirming the diagnosis of HT.

Development and implementation of blood pressure screening and referral guidelines for German community pharmacists

Involvement of community pharmacists in the detection and control of hypertension improves patient care. However, current European or North‐American guidelines do not provide specific guidance how to implement collaboration between pharmacists and physicians, especially when and how to refer patients with undetected or uncontrolled hypertension to a physician. The German Society of Cardiology and the ABDA – Federal Union of German Associations of Pharmacists developed and tested referral recommendations for community pharmacists, embedded in two guideline worksheets. The project included a guideline‐directed blood pressure (BP) measurement and recommendations when patients should be referred to their physician. A “red flag” referral within 4 weeks was recommended when SBP was >140 mm Hg or DBP >90 mm Hg (for subjects <80 years), and >160 mm Hg or >90 mm Hg (≥80 years) in undetected individuals, or >130 mm Hg or >80 mm Hg (<65 years) and >140 mm Hg or >80 mm Hg (≥65 years) in treated patients. BP was measured in 187 individuals (86 with known hypertension, mean [±SD] age 62 ± 15 years, 64% female, and 101 without known hypertension, 47 ± 16 years, 75% female) from 17 community pharmacies. In patients with hypertension, poorly controlled BP was detected in 55% (n = 47) and were referred. A total of 16/101 subjects without a history of hypertension were referred to their physician because of uncontrolled BP. Structured BP testing in pharmacies identified a significant number of subjects with undetected/undiagnosed hypertension and patients with poorly controlled BP. Community pharmacists could play a significant role in collaboration with physicians to improve the management of hypertension.

Pharmacist's role in hypertension management: a review of key randomized controlled trials

Hypertension (HTN) is a leading cause of death and disability throughout the world. Yet, despite widely available treatment options, blood pressure (BP) control rates have remained relatively stagnant. One approach to address this issue is through collaborative care models, particularly those employing pharmacists. Numerous randomized controlled trials (RCT) have demonstrated the effectiveness of pharmacist interventions to improve BP control across primary care, community-based, and telemedicine models. A meta-analysis of 39 RCTs has demonstrated that pharmacist interventions significantly reduce both systolic and diastolic BP compared with controls across diverse patient populations. Pharmacists can contribute to HTN management in a variety of ways, including assisting with out-of-office monitoring, providing education, identifying and resolving nonadherence, and titrating antihypertensive therapy to achieve BP control. In this review, we discuss key trials conducted in recent years that support the role of pharmacists in HTN management and provide guidance on practical considerations for working collaboratively with pharmacists to improve BP control.

Pharmacists interventions using Bluetooth technology and telehealth to improve blood pressure-A pilot study

OBJECTIVES

To assess patients' knowledge of blood pressure (BP) and their comfort level with using technology, including a Bluetooth-enabled BP device and pharmacist telemonitoring. The secondary objective was to discover if pharmacist interventions improved BP readings.

SETTING

The study took place in Pharmacy Plus and the Family Medicine Department at the University of South Florida in Tampa, FL.

PRACTICE DESCRIPTION

The pharmacists within Pharmacy Plus and the Family Medicine Department are part of the interdisciplinary team providing care to patients and seeking to achieve optimal patient outcomes. Pharmacy Plus breaks away from the traditional behind-the-counter model using innovative technology to create a personalized experience for patients.

PRACTICE INNOVATION

During this pilot study, the patients received a Bluetooth-enabled BP monitor and were asked to obtain their BP readings at least once daily for 6 weeks. The patients' electronic health records automatically captured the BP readings, which were reviewed by the study pharmacists. The patients had an appointment with the pharmacists once weekly via a telehealth platform through which they were counseled on their weekly average BP, BP goals, lifestyle modifications, and proper use of the devices.

EVALUATION

The patients completed a prestudy survey assessing their baseline knowledge of BP, comfort level when using technology, and ease in working with pharmacists. Reliability and satisfaction in using the BP device and telehealth communication with pharmacists were also assessed poststudy.

RESULTS

Twelve patients enrolled, with 9 completing the study. There was a statistically significant increase in patients' knowledge of BP and an improvement in the recommended lifestyle modifications. In addition, comfort level regarding communication with the pharmacist was statistically significantly improved. The patients responded positively to using the Bluetooth-enabled BP monitor and telehealth for receiving health care services.

CONCLUSION

Using Bluetooth-enabled BP monitors that report results in real time into electronic health records, along with pharmacist interventions within a team-based care model, may result in improved BP control and patient outcomes.
