Effectiveness of a School‐Based Educational Intervention to Improve Hypertension Control Among Schoolteachers: A Cluster‐Randomized Controlled Trial

Background The control of hypertension is low in low‐ and middle‐income countries like India. We evaluated the effects of a nurse‐facilitated educational intervention in improving the control rate of hypertension among school teachers in India. Methods and Results This was a cluster‐randomized controlled trial involving 92 schools in Kerala, which were randomly assigned equally into a usual care group and an intervention group. Participants were 402 school teachers (mean age, 47 years; men, 29%) identified with hypertension. Participants in both study groups received a leaflet containing details of a healthy lifestyle and the importance of regular intake of antihypertensive medication. In addition, the intervention participants received a nurse‐facilitated educational intervention on hypertension control for 3 months. The primary outcome was hypertension control. Key secondary outcomes included systolic blood pressure, diastolic blood pressure, and the proportion of participants taking antihypertensive medications. For the primary outcome, we used mixed‐effects logistic regression models. Two months after a 3‐month educational intervention, a greater proportion of intervention participants (49.0%) achieved hypertension control than the usual care participants (38.2%), with an odds ratio of 1.89 (95% CI, 1.06–3.35), after adjusting for baseline hypertension control. The odds of taking antihypertensive medications were 1.6 times higher in the intervention group compared with the usual care group (odds ratio, 1.62; 95% CI, 1.08–2.45). The reduction in mean systolic blood pressure was significantly greater in the intervention group by 4.2 mm Hg (95% CI, −7.2 to −1.1) than in the usual care group. Conclusions A nurse‐facilitated educational intervention was effective in improving the control and treatment rates of hypertension as well as reducing systolic blood pressure among schoolteachers with hypertension.

Hypertension Control and Guideline-Recommended Target Blood Pressure Goal Achievement at an Early Stage of Hypertension in the UAE

(1) Background: The present study aimed to assess the changes in blood pressure (BP) within the first 6 months of treatment initiation in a newly treated hypertensive cohort and to identify the factors that are associated with achieving the target BP recommended by the American (ACC/AHA, 2017), European (ESC/ESH, 2018), United Kingdom (NICE, 2019), and International Society of Hypertension (ISH, 2020) guidelines. (2) Methods: We analyzed 5308 incident hypertensive outpatients across Abu Dhabi, United Arab Emirates (UAE), in 2017; each patient was followed up for 6 months. Hypertension was defined as a BP of 130/80 mmHg according to the ACC/AHA guidelines and 140/90 mmHg according to the ESC/ESH, NICE, and ISH guidelines. Multiple logistic regression was used to identify factors associated with achieving the guideline-recommended BP targets. (3) Results: At baseline, the mean BP was 133.9 ± 72.9 mmHg and 132.7 ± 72.5 mmHg at 6 months. The guideline-recommended BP targets were 39.5%, 43%, 65.6%, and 40.8%, according to the ACC/AHA, ESC/ESH, NICE, and ISH guidelines, respectively. A BMI of <25 kg/m2 was associated with better BP control according to the ACC/AHA (odds ratio (OR) = 1.26; 95% confidence interval (CI) = 1.07–1.49), ESC/ESH (OR = 1.27; 95% CI = 1.08–1.50), and ISH guidelines (OR = 1.22; 95% CI = 1.03–1.44). Hypertension treated in secondary care settings was more likely to achieve the BP targets recommended by the ACC/AHA (1.31 times), ESC/ESH (1.32 times), NICE (1.41 times), and ISH (1.34 times) guidelines. (4) Conclusions: BP goal achievement was suboptimal. BP control efforts should prioritize improving cardiometabolic goals and lifestyle modifications.

Development and evaluation of a package to improve hypertension control in Nigeria [DEPIHCON]: study protocol for a cluster randomized controlled trial

Background: Nigeria’s healthcare system capacity to stem the increasing trend in hypertension is limited in coverage, scope and manpower. Use of trained community-based care providers demonstrated to be an effective complement in improving access to, and supporting healthcare delivery has not been adequately examined for hypertension care in Nigeria. This study is proposed to evaluate the effectiveness of using trained Community-based Oriented Resource Persons (CORPs) to improve hypertension control in Nigeria. Methods: An intervention study will be conducted in three states using mixed method design. First, is a baseline survey using a semi-structured pre-tested questionnaire to collect information on demographics, clinical data, knowledge, occurrence and risk factors of hypertension among 1,704 adults ≥18 years. Focus Group Discussions (FGD) and Key Informant Interviews (KII) will be conducted to explore community’s experience of hypertension, challenges with hypertension management, and support required to improve control in 10 selected communities in each state. The second is a cluster randomized controlled trial to evaluate effect of a package on reduction of blood pressure (BP) and prevention of cardiovascular (CVD) risk factors among 200 hypertensive patients to be followed up in intervention and control arms over a six-month period in each state. The package will include trained CORPs conducting community-based screening of BP and referral, diagnosis confirmation and initial treatment in the health facility, followed by monthly home-based follow-up care and provision of health education on hypertension control and healthy lifestyle enhanced by phone voice message reminders. In the control arm, the usual care (diagnosis, treatment and follow up care in hospital of patient’s choice) will continue. Third, an end-line survey will be conducted in both intervention and control communities to evaluate changes in mean BP, control, knowledge, and proportion of other CVD risk factors. In addition, FGD and KII will be used to assess participants’ perceived quality and acceptability of the interventions as delivered by CORPs.Discussion: This research is expected to create awareness, improve knowledge, perception, behaviours, attitude and practices that will reduce hypertension in Nigeria. Advocacy for buy-in and scale up of using CORPs in hypertension care by the government is key if found to be effective. Trial registration: PACTR Registry- PACTR202107530985857.
