Comparative Effectiveness of Implementation Strategies for Blood Pressure Control in Hypertensive Patients: A Systematic Review and Meta-analysis.

ABSTRACT: Background:The prevalence of hypertension is high and is increasing worldwide, whereas the proportion of controlled hypertension is low. Purpose:To assess the comparative effectiveness of 8 implementation strategies for blood pressure (BP) control in adults with hypertension. Data Sources:Systematic searches of MEDLINE and Embase from inception to September 2017 with no language restrictions, supplemented with manual reference searches. Study Selection:Randomized controlled trials lasting at least 6 months comparing the effect of implementation strategies versus usual care on BP reduction in adults with hypertension. Data Extraction:Two investigators independently extracted data and assessed study quality. Data Synthesis:A total of 121 comparisons from 100 articles with 55 920 hypertensive patients were included. Multilevel, multicomponent strategies were most effective for systolic BP reduction, including team-based care with medication titration by a nonphysician (-7.1 mm Hg [95% CI, -8.9 to -5.2 mm Hg]), team-based care with medication titration by a physician (-6.2 mm Hg [CI, -8.1 to -4.2 mm Hg]), and multilevel strategies without team-based care (-5.0 mm Hg [CI, -8.0 to -2.0 mm Hg]). Patient-level strategies resulted in systolic BP changes of -3.9 mm Hg (CI, -5.4 to -2.3 mm Hg) for health coaching and -2.7 mm Hg (CI, -3.6 to -1.7 mm Hg) for home BP monitoring. Similar trends were seen for diastolic BP reduction. Limitation:Sparse data from low- and middle-income countries; few trials of some implementation strategies, such as provider training; and possible publication bias. Conclusion:Multilevel, multicomponent strategies, followed by patient-level strategies, are most effective for BP control in patients with hypertension and should be used to improve hypertension control.

Project description:BACKGROUND:The prevalence of hypertension is a major public health challenge. Despite it being highly preventable, hypertension is responsible for a significant proportion of global morbidity and mortality. Common methods for controlling hypertension include prescribing anti-hypertensive medication, a pharmacological approach, and increasing physical activity, a behavioural approach. In general, little is known about the comparative effectiveness of pharmacological and behavioural approaches for reducing blood pressure in hypertension. A previous network meta-analysis suggested that physical activity interventions may be just as effective as many anti-hypertensive medications in preventing mortality; however, this analysis did not provide the comparative effectiveness of these disparate modes of intervention on blood pressure reduction. The primary objective of this study is to use network meta-analysis to compare the relative effectiveness, for blood pressure reduction, of different approaches to increasing physical activity and different first-line anti-hypertensive therapies in people with hypertension. METHODS:A systematic review will be conducted to identify studies involving randomised controlled trials which compare different types of physical activity interventions and first-line anti-hypertensive therapy interventions to each other or to other comparators (e.g. placebo, usual care) where blood pressure reduction is the primary outcome. We will search the Cochrane Library, MEDLINE and PsycInfo. For studies which meet our inclusion criteria, two reviewers will extract data independently and assess the quality of the literature using the Cochrane Risk of Bias Tool. Network meta-analyses will be conducted to generate estimates of comparative effectiveness of each intervention class and rankings of their effectiveness, in terms of reduction of both systolic and diastolic blood pressure. DISCUSSION:This study will provide evidence regarding the comparability of two common first-line treatment options for people with hypertension. It will also describe the extent to which there is direct evidence regarding the comparative effectiveness of increasing physical activity and initiating anti-hypertensive therapy.

Project description:BackgroundThe morning blood pressure surge (MBPS) is related to an exaggerated risk of cardiovascular diseases and mortality. With increasing attention on circadian change in blood pressure and extensive use of ambulatory blood pressure monitoring (ABPM), chronotherapy that administration of medication according to biological rhythm, is reported to improve cardiovascular outcomes. The aim of this study is to evaluate the influence of chronotherapy of antihypertensive drugs upon MBPS in hypertensive patients.MethodsA search strategy was applied in Ovid MEDLINE, EMBASE, Cochrane (Wiley) CENTRAL Register of Controlled Trials, Cochrane Database of Systematic Reviews, and the Chinese Biomedical literature database. No language and date restrictions. Randomized controlled trials (RCT) assessing the efficacy of evening and morning administration of the same medications in adult patients with primary hypertension were included.ResultsA total of ten trials, comprising 1724 participants with a mean age of 61 and 51% female, were included in this study. Combined analysis observed significant reduction of MBPS (- 5.30 mmHg, 95% CI - 8.80 to - 1.80), night-time SBP (- 2.29 mmHg, 95% CI - 4.43 to - 0.15), night-time DBP (- 1.63 mmHg, 95 %CI - 3.23 to - 0.04) and increase in night blood pressure dipping (3.23%, 95% CI 5.37 to 1.10) in evening dosage compared with traditional morning dosage of blood pressure-lowering drugs. No significant difference was found in the incidence of overall adverse effects (RR 0.65, 95% CI 0.30 to 1.41) and withdrawal due to adverse effects (RR 0.95, 95% CI 0.53 to 1.71).ConclusionsOur study suggested that evening administration of antihypertensive medications exerted better blood pressure-lowering effect on MBPS compared with conventional morning dosage. Safety assessment also indicated that the evening regimen did not increase the risk of adverse events. However, endpoint studies need to be carried out to confirm the significance and feasibility of this treatment regimen in clinical practice.

Project description:BackgroundThe rate of blood pressure control among hypertensive patients is poor and the reasons for poor control of blood pressure remain poorly understood globally.ObjectiveTo assess the rate of blood pressure control among adult hypertensive patients at Jimma University Specialized Hospital.Materials and methodsWe conducted a hospital based cross sectional study among adult hypertensive patients at Jimma University Specialized Hospital hypertension clinic from March 4, 2015 to April 3, 2015. Data on sociodemographic characteristics of the participants and adherence to antihypertensive medication(s) were collected from patients by face to face interview using a pretested structured questionnaire. Comorbidities, antihypertensive medication(s) and blood pressure measurements were collected retrospectively from medical records. Medication adherence was assessed using Morisky's Medication Adherence Scale-8 score. We did the statistical analysis using chi-square test and binary logistic regression with level of α set at 0.05. Statistical significance was considered for variables with p<0.05.ResultsOut of 311 participants, 286 patients were eligible and were studied. More than half, 154 (53.8%), of the participants were males. The mean age of the participants was 54.8± 12.6 years (range 26 to 94). The majority, 196 (68.53%), of the participants were taking more than one antihypertensive medication. More than one third (39.5%) of the participants were non adherent to their medication(s). The rate of blood pressure control was 50.3%. In a univariate logistic regression analyses, age ≥65 years old (P = 0.008), physical inactivity (p<0.001), chat chewing (P<0.001), adding salt to food (P<0.001), and coffee use (P<0.001) are significantly associated with uncontrolled blood pressure.ConclusionAlmost half of the hypertensive patients on follow up had uncontrolled blood pressure. We recommend better health education and care of patients to improve the rate of blood pressure control at the hospital.

Project description:BackgroundControlling blood pressure (BP) leads to significant reduction in cardiovascular risks and associated deaths. In Ethiopia, data is scarce about the level and determinants of optimal BP control among hypertensive patients. This study aimed to assess the prevalence and associated factors of optimal BP control among hypertensive patients attending at a district hospital.MethodsA hospital-based, cross-sectional study was conducted among 392 hypertensive patients who were on treatment and follow-up at a district hospital. A structured questionnaire adopted from WHO approach was prepared to collect the data. Medication adherence was measured by the four-item Morisky Green Levine Scale, with a score ≥3 defined as "good adherence". Blood pressure was measured, and optimal BP control was 0DEFined as systolic BP < 140 mmHg and diastolic BP<90 mmHg. Both binary and multivariable logistic regressions models were fitted to identify correlates of optimal BP control. All statistical tests were two-sided and a p values <0.05 was considered for statistical significance.ResultsThe mean age of the participants was 58 years (SD±13 years). Over half (53.8%) were females. Three quarters (77.3%) of the participants were adherent to their medications. The overall proportion of participants with optimally controlled BP was 42.9%.Female sex (Adjusted Odd Ratio(AOR) = 1.94, 95% CI: 1.15, 3.26), age older than 60 years (AOR = 2.95, 95% CI: 1.18, 7.40), consumption of vegetables on most days of the week (AOR = 2.16, 95% CI: 1.25, 3.73), physical activity (AOR = 4.85, 95% CI: 2.39, 9.83), and taking less than three drugs per day (AOR = 3.04, 95% CI: 1.51, 6.14) were positively associated with optimally controlled BP. Poor adherence to medications (AOR = 0.18, 95% CI: 0.09, 0.35), having asthma comorbidity (AOR = 0.33, 95% CI:0.12, 0.88) and use of top added salt on a plate (AOR = 0.20, 95% CI:0.11, 0.36) were negatively associated with optimal BP control.ConclusionA higher proportion of hypertensive patients remain with un-controlled BP. Modifiable risk factors including poor adherence to medications, lack of physical exercise, adding salt into meals, being on multiple medications and comorbidities were significantly and independently associated with poor BP control. Evidence-based, adherence-enhancing and healthy life style interventions should be implemented.

Project description:In the Systolic Blood Pressure Intervention Trial (SPRINT), adults at high risk for cardiovascular disease who received intensive systolic blood-pressure control (target, <120 mm Hg) had significantly lower rates of death and cardiovascular disease events than did those who received standard control (target, <140 mm Hg). On the basis of these data, we wanted to determine the lifetime health benefits and health care costs associated with intensive control versus standard control.We used a microsimulation model to apply SPRINT treatment effects and health care costs from national sources to a hypothetical cohort of SPRINT-eligible adults. The model projected lifetime costs of treatment and monitoring in patients with hypertension, cardiovascular disease events and subsequent treatment costs, treatment-related risks of serious adverse events and subsequent costs, and quality-adjusted life-years (QALYs) for intensive control versus standard control of systolic blood pressure.We determined that the mean number of QALYs would be 0.27 higher among patients who received intensive control than among those who received standard control and would cost approximately $47,000 more per QALY gained if there were a reduction in adherence and treatment effects after 5 years; the cost would be approximately $28,000 more per QALY gained if the treatment effects persisted for the remaining lifetime of the patient. Most simulation results indicated that intensive treatment would be cost-effective (51 to 79% below the willingness-to-pay threshold of $50,000 per QALY and 76 to 93% below the threshold of $100,000 per QALY), regardless of whether treatment effects were reduced after 5 years or persisted for the remaining lifetime.In this simulation study, intensive systolic blood-pressure control prevented cardiovascular disease events and prolonged life and did so at levels below common willingness-to-pay thresholds per QALY, regardless of whether benefits were reduced after 5 years or persisted for the patient's remaining lifetime.

Project description:IntroductionThe effectiveness of telmisartan has been reported in Indian clinical trials; however, real-world data are limited. We aimed to provide real-world evidence regarding the effectiveness of telmisartan as monotherapy or in combination with other antihypertensive drugs (AHDs) in Indian patients with essential hypertension.MethodsElectronic medical record data of adult patients diagnosed with essential hypertension (≥ 140/90 mmHg) and who were prescribed telmisartan as mono- or add-on therapy were retrospectively analyzed. Patients were classified according to the number of AHD classes prescribed on initiating telmisartan. Change in systolic and diastolic blood pressure (SBP and DBP) after a month of treatment and the proportion of patients who achieved treatment goals according to the 2018 European Society of Cardiology/European Society of Hypertension guidelines were evaluated.ResultsA majority (90.6%) of the 1304 patients included in the study were on telmisartan monotherapy or telmisartan + 1 AHD. The mean (95% confidence interval [CI]) change in the telmisartan monotherapy group was SBP (-13.3 [-14.6, -12.0] mmHg) and DBP (-7.2 [-7.9, -6.5] mmHg), and the mean (95% CI) change in the telmisartan + 1 AHD group was SBP (-10.8 [-13.1, -8.5] mmHg) and DBP (-6.5 [-7.7, -5.3] mmHg) (P < 0.001 for all). SBP and DBP goals were achieved by 35.9% and 47.3% of patients on telmisartan monotherapy and by 35.9% and 46.8% of patients on telmisartan + 1 AHD. Among patients with comorbid diabetes, the mean (95% CI) change in the telmisartan monotherapy group was SBP (-13.3 [-15.0, -11.6] mmHg) and DBP (-7.3 [-8.2, -6.5] mmHg), and the mean (95% CI) change in the telmisartan + 1 AHD group was SBP (-13.0 [-16.5, -9.5] mmHg) and DBP (-6.9 [-8.7, -5.1] mmHg) (P < 0.001 for all). SBP and DBP goals were achieved by 31.7% and 39.7% of patients on telmisartan monotherapy and by 31.9% and 41.8% of patients on telmisartan + 1 AHD.ConclusionTelmisartan may be a good candidate for blood pressure control in Indian patients with essential hypertension and comorbidities.
