Technology-enabled Management Versus Usual Care for Blood Pressure
HypertensionTwo arm parallel randomized clinical trial

Heart to Heart: BP Control Partners
HypertensionThe goal of this clinical trial is to compare a new model of care that uses cellular-enabled home blood pressure (BP) telemonitoring and combines it with team-based BP control using a pharmacist to help manage BP medications and to give patients advice on diet and exercise, to an enhanced usual care group that only receives the monitoring device and basic instructions, in individuals with a history of uncontrolled hypertension. The main question[s] it aims to answer are: Among patients with a history of uncontrolled hypertension, evaluate the impact of team-based care using technology-enabled monitoring on improving goal-directed systolic blood pressure (SBP) levels relative to enhanced usual care (primary). Assess the potential for heterogeneity of treatment effects by race, age, sex, and social deprivation index (secondary). Examine the impact of the intervention on hypertension self-efficacy, medication adherence, timeliness of medication change, satisfaction with care, adoption of home BP monitoring, and the change in mean BP in diverse patients, many of whom have adverse social determinants of health (SDOH) (secondary/exploratory). Both groups will be asked to check their BP at home using a cellular-enabled home BP monitoring device that's provided. Patients in the Technology enabled Team Care (TTC) intervention group will have regular phone calls from a clinically trained and experienced pharmacist that works with their doctor/provider and who has reviewed their home BP readings. This pharmacist will help them adjust their medicines, provide brief nutrition and physical activity advice, and may refer them for help with any social challenges (not enough proper food, transportation problems, etc.) that they may be experiencing. An enhanced usual care group will serve as the comparison group and will receive the BP cuff monitoring device and basic instructions but will not receive ongoing monitoring or team care as described above. Researchers will compare the effect of the TTC intervention model to enhanced usual care to assess the impact on SBP levels at 6 and 12 months follow-up, as well as on a variety of patient-reported outcomes.

Effectiveness of a Community Health Worker Delivered Care Intervention for Hypertension Control...
Hypertension; Community Health WorkersOver 80% of the morbidity and mortality related to non-communicable diseases (NCDs) occurs in low-income and middle-income countries (LMICs). Community health workers (CHWs) may improve disease control and medication adherence among patients with NCDs in LMICs, but data are scarce, particularly in sub-Saharan African settings. In Uganda, and the majority of LMICs, management of uncontrolled blood pressure remains limited in constrained health systems. Intervening at the primary care level, using CHWs to improve medical treatment outcomes has not been well studied. The investigators aim to determine the effectiveness of a CHW-led intervention in blood pressure control among confirmed hypertensive patients and patient-related factors associated with uncontrolled hypertension. Methods: Conduction of a stepped-wedge cluster randomized controlled trial study of 869 adult patients with hypertension attending two NCD clinics to test the effectiveness, acceptability and fidelity of a CHW-led intervention. The multi-component intervention will be centered on monthly household visits by trained CHWs for a period of seven months, consisting of the following; (1) blood pressure and sugar monitoring; (2) BMI monitoring; (3) cardiovascular disease risk assessment; (4) Using checklists to guide monitoring and referral to clinics; (5) healthy lifestyle counselling and education. During home visits, CHWs will remind patients of follow-up visits. The investigators will measure blood pressure at baseline and 3-monthly for the entire cohort. The investigators will additionally test acceptability of the intervention and fidelity over the course of the intervention. The investigators will conduct individual-level mixed effects analyses of study data, adjusting for time and clustering by patient and community. Conclusion: The results of this study will inform community delivered hypertension management across a range of LMIC settings.

Control of Hypertension and diAbetes in MINas Gerais
Arterial HypertensionDiabetes MellitusHypertension and diabetes mellitus (DM) are highly prevalent in low and middle-income countries, and the proportion of patients with uncontrolled diseases is higher than in high income countries. Innovative strategies are required to surpass barriers of low sources, distance, and quality of healthcare. Our aim is to assess the uptake and effectiveness of the implementation of an integrated multidimensional strategy in the primary care setting, for the management of patients with hypertension and diabetes mellitus (DM) in Brazil. This is a scale up implementation study that has mixed-methods, and comprehends four steps: (1) needs assessment, including a standardized structured questionnaire and focus groups with healthcare practitioners; (2) baseline period, three months before the implementation of the intervention; (3) cluster randomized controlled trial (RCT) with a 12-month follow-up period; and (4) a qualitative study after the end of follow-up. The cluster RCT will randomize 35 centres to intervention (n= 18) or usual care (n= 17). Patients ≥18 years-old, with diagnosis of hypertension and/or DM, of five Brazilian cities in a resource-constrained area will be enrolled. The intervention consists of a multifaceted strategy, with a multidisciplinary approach, including telehealth tools (decision support systems, short message service, telediagnosis), continued education with an approach to issues related to the care of people with hypertension and diabetes in primary care, including pharmacological and non-pharmacological treatment and behavioural change. The project has actions focused on professionals and patients.

Peripheral Vascular Effects of Sulfhydryl-containing Antihypertensive Pharmacotherapy on Microvessels...
Hypertension,EssentialHigh blood pressure can cause physical changes to the blood vessels of the body (remodeling). If a person who has high blood pressure also has a lot of blood vessel remodeling with their condition, they are more likely to have poor results with medical treatment for hypertension. The researchers examine the impact of different classes of drugs that doctors use to treat high blood pressure (hypertension) on blood vessel remodeling. Some drugs that doctors prescribe for their patients contain a "sulfhydryl group" (a sulfur atom bonded to a hydrogen atom). Drugs that have the sulfhydryl group may reduce blood vessel remodeling more that drugs that do not. For this study, participants who have high blood pressure perform the experiments, take a drug for 16-weeks to lower blood pressure, and repeat the experiments. The researchers randomly assign one of three drugs to participants who have high blood pressure: a diuretic ("water pill"), a drug containing a sulfhydryl (SH) group, or a drug that does not contain a sulfhydryl group. Participants who do not have high blood pressure perform the experiments, but do not take any of the drugs. In some of our experiments, the researchers use a technique called "microdialysis" (MD). With MD, the researchers perfuse some research drugs into the skin on the forearm through tiny tubing that mimics capillaries. These MD drugs mimic or block substances the body naturally makes to control the small blood vessels in the skin. The drugs remain in nickel-sized areas around the tubing and do not go into the rest of the body. The researchers also analyze very small skin samples (skin biopsy) obtained from the forearm. Lastly, the researchers use a standard technique called "flow mediated dilation" (FMD) that uses blood pressure cuffs and ultrasound to look at the health of larger blood vessels in the body. FMD includes placing a small tablet of nitroglycerin under the tongue during part of the test.

Implementation of a Comprehensive Intervention on Hypertension(HTN) and Type 2 Diabetes Mellitus(DM)...
HypertensionDiabetes Mellitus1 moreBackground: The disease burden of hypertension(HTN) and type 2 diabetes mellitus(DM) is rising rapidly in China.Comprehensive interventions(Implementation strategies for providers and interventions for patients) are critical to strengthen primary health care systems and address the burden of multiple comorbidities. In order to promote equal access to health services and narrow the gap in population health, China has launched the national Essential Public Health Services Equity Programme (EPHSEP) nationwide. EPHSEP contains guidelines for health management services for HTN and type 2 DM. The program has been in operation for 10 years. However, the management of HTN and type 2 DM in China is far from satisfactory. The purpose of this study is to understand current control and management situation of HTN and type 2 DM, investigate the barriers and facilitators in the implementation of HTN and type 2 DM service delivery standards, propose feasible implementation strategies,implement in certain areas,and to evaluate the effectiveness of interventions and the performance and impact of implementation strategies. Methods: Based on previous work,four community health service centres and four township health centres will be selected in West Coast District of Qingdao city of Shandong province,Suzhou City of Jiangsu province, Changsha city of Hunan province and Luohe city of Henan Province.In each of the four provinces,one community health service center and one township health center will be selected.Two community health service centres and two township health centres will be selected as the intervention groups, and the other community health service centres and township health centres will be selected as the control groups. The study will be divided into three phases: Phase 1, 2 and 3. Phase 1 and phase 2 cross-sectional studies are the basis for phase 3 intervention studies. Phase 1 will be conducted from March 2022 to April 2022.In phase 1, a quantitative questionnaire survey will be conducted among 5464 HTN and 7040 type 2 DM patients in 8 community health service centers to obtain the data of awareness rate, screening rate, diagnosis rate, treatment rate, control rate and management service of hypertension and type 2 diabetes patients,so as to understand current control and management situation of HTN and type 2 DM. Phase 2 will be conducted in April 2022. In phase 2, about 64 medical staff and related managers providing HTN and type 2 DM health management services and 80 patients with HTN and type 2 DM in 8 community health service centers will be investigated through qualitative interviews,so as to investigate the barriers and facilitators in the implementation of HTN and type 2 DM service delivery standards and to propose feasible implementation strategies. Phase 3 will be conducted a mixed-methods type 2 hybrid effectiveness-implementation study from May 2022 to January 2023. Interventions are divided into four levels through a cascading model of screening, diagnosis, treatment, and control. Implementation strategies are divided into 6 categories according to Implementation Mapping: Capacity-building strategies(Recruit, designate, and train for leadership; Work with educational institutions), Supervision(Provide clinical supervision), Integration strategies(Remind clinicians; Use data warehousing techniques), Implementation process Strategies(Identify and prepare champions; Identify early adopters; Inform local opinion leaders; Involve patients/consumers and family members; Obtain and use patients/consumers and family feedback), Dissemination strategies(Make training dynamic), Scale-up strategies(Use train-the-trainer strategies;Place innovation on fee for service lists/formularies). We will adopt between site design to select 4(2*2 )community health service centers and 4(2*2)township health centers, among which 2 community health service centers and 2 township health centers will implement the strategy, while the other selected sites will not implement the strategy. The 2*2 community health service centers and 2*2 township health centers will be divided into group matching control and self pre- and post-control. In phase 3, 2280 patients with HTN and 2656 patients with type 2 DM will be surveyed by quantitative questionnaire, and about 64 medical staff and related managers providing HTN and type 2 DM health management services will be surveyed by qualitative interview. This is to implement improved implementation strategies and to assess the effectiveness of interventions and the performance and impact of implementation strategies.

Remote Monitoring for Equity in Advancing Control of Hypertension
HypertensionThe goal of this study is to support patients with hypertension self-management using both home blood pressure monitors and digital messaging programs. The investigators will first engage patients with technology training to use home monitors, online portal websites to view their medical record information online, and texting and mobile phone applications. Then investigators will assess the effectiveness of home blood pressure monitors and enhanced patient-clinician digital communication on blood pressure control during a 12-month intervention.
