Study summary

The ADHINCRA Program is a bundle of multilevel evidence-based interventions that address multiple predictors of controlled hypertension, including patient-, provider-, and health system-level factors. The successful implementation of the ADHINCRA program will provide a rigorous and scalable model for improving hypertension control in Africa, which would ultimately reduce the risk of cardiovascular disease, stroke and kidney disease.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

    Behavioral: ADHINCRA Program

  • Experimental
    Cohort 2

    This cohort will begin the ADHINCRA Program 3 months after Cohort 1.

    Behavioral: ADHINCRA Program

  • Experimental
    Cohort 3

    This cohort will begin the ADHINCRA Program 6 months after Cohort 1.

    Behavioral: ADHINCRA Program

  • Experimental

    This cohort will begin the ADHINCRA Program 9 months after Cohort 1.

    Behavioral: ADHINCRA Program

Interventions

  • BehavioralADHINCRA Program

    The ADHINCRA Program is a nurse-led intervention that includes the use of home blood pressure monitoring, a mobile health app, lifestyle counselling, and a simplified hypertension treatment protocol to achieve blood pressure control among people diagnosed with hypertension.

What researchers measure

Primary outcomes

  1. Number of participants with systolic blood pressure <140 mmHg

    Blood pressure control among participants defined as systolic blood pressure \<140 mmHg

    Time frame: Baseline and 12 months post-randomization

Secondary outcomes

  1. Number of participants with diastolic blood pressure <90 mmHg

    Blood pressure control as assessed by diastolic blood pressure \<90mmHg

    Time frame: Baseline, 12 months, 24 months post-randomization

  2. Medication adherence as assessed by Hill-Bone Medication Adherence Scale

    Adherence to medications prescribed per the ADHINCRA Program treatment protocol. The total score ranges from 14 - 56. Higher score is better adherence.

    Time frame: Baseline, 12 months, 24 months post-randomization

  3. Percentage of sites that adopt and maintain the intervention as assessed by the Pragmatic Robust Implementation and Sustainability Model

    Use the Pragmatic Robust Implementation and Sustainability Model (PRISM) to evaluate the reach, adoption, maintenance of the ADHINCRA Program

    Time frame: Baseline, 12 months, 24 months post-randomization

  4. Difference in cost of intervention compared to usual care as assessed by the Pragmatic Robust Implementation and Sustainability Model

    Use the Pragmatic Robust Implementation and Sustainability Model (PRISM) to evaluate the cost-effectiveness of the ADHINCRA Program

    Time frame: Baseline, 12 months, 24 months post-randomization
