About this study

Official title: Control of Hypertension and diAbetes in MINas Gerais: Assessment of the Impact of Implementing a Multidimensional Strategy for Management of Patients With Systemic Arterial Hypertension and Diabetes Mellitus in Primary Care

Hypertension 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.

Read the detailed description

This scale up implementation study has mixed-methods, and comprehends four steps: (1) needs assessment, (2) baseline period, (3) cluster RCT and (4) qualitative study. The RE-AIM planning and evaluation framework will be used in this research project, which includes: reach (R), efficacy (E), adoption (A), implementation (I), and maintenance (M). The Adaptation Framework might be used as well, in case adaptations need to be conducted during the intervention, taking into account the COVID-19 pandemic and possible new waves.

  1. A standardized structured questionnaire will be developed with open questions about the physical and technological structure, human resources and challenges managing patients with hypertension and DM, in order to carry out a brief situational diagnosis.
  2. A baseline period of three months will be established to assess the basal condition of patients. Individuals will be assessed for blood pressure and glycohemoglobin measurements; functional performance (2-minute step test); anthropometric measurements (weight, height, and waist circumference); physical inactivity; alcohol consumption; smoking; and food consumption markers.
  3. A two-arm parallel cluster RCT will be conducted, with a baseline period of three months and a subsequent follow-up period of 12 months from the start of the intervention. To avoid possible contamination within the same primary care unit, randomization will take place at a primary care centre level: each centre will be randomized to the control or the intervention arm, rather than individual patients. Randomization will be performed by computer software and stratified by geographic location and municipality, to ensure balance between arms.
  4. At the end of the cluster-randomized controlled trial, another qualitative study will be carried out using the FG technique, in order to assess barriers and suggestions for improvement of each component of the implemented multidimensional strategy.

To calculate the sample size, the investigators took into account the proportion of patients with controlled hypertension (33%) and DM (37%) observed at baseline in the pilot study (data not published), and an absolute increase of 6% in these proportions one year after the implementation of the intervention, with a power of 0.80, level of significance of 0.05 and intra cluster correlation coefficient of 0.026. The calculated sample was 34 primary care centres, 17 in each arm, with a minimum of 148 participants in each centre. As the total number of primary care centres in the five municipalities is 35, the investigators planned to include one extra unit in the intervention arm. Taking into account a drop out rate of up to 17.8%, the total number of included individuals will be 180.

Study groupRoleWhat they receive
InterventionExperimentalEighteen primary care centers will be randomized to the intervention arm, which consists of a multidimensional strategy, with a multidisciplinary approach, for the management of patients with hypertension and diabetes in the primary care setting. It is going to include: 1. Telehealth tools: clinical decision support system for primary care professionals to support the care of patients with hypertension and diabetes; clinical decision support system to support community health agents (ACS), for use in home visits; asynchronous teleconsultations; telediagnosis for digital electrocardiogram and retinography reports; text messages to patients, to provide information, education, improve adherence to treatment and encourage patients to promote health; 2. Continued education for health professionals; 3. Strengthening the educational groups and promotion of lifestyle changes, with a focus on promoting healthy eating and reducing sedentary behavior.
Receives: Other: Multidimensional intervention
Usual careNo interventionSeventeen primary care centers will be randomized to usual care.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Composite outcome of proportion of patients with controlled disease

    (i) for hypertension, the proportion (%) of patients with systolic blood pressure (SBP) <140 mmHg and diastolic blood pressure (DBP) < 90 mmHg; (ii) for diabetes, the proportion (%) of patients with glycohemoglobin ≤ 7% if the age < 60 years, or < 8% if the age is ≥ 60 years; (iii) for those with both hypertension and diabetes, proportion (%) of patients with both diseases controlled.

    Measured: 12 months

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite outcome of proportion of patients with controlled disease (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
