About this trial

The burden of hypertension and related cardiovascular diseases, stroke, and end-stage kidney disease is disproportionately high in Black populations, especially in the South. The Blood Pressure Lowering Strategies to Eliminate Hypertension Disparities (BLESSED) cluster randomized trial aims to test the effectiveness, implementation, and sustainability of a community health worker (CHW)-led multifaceted intervention compared to enhanced usual care for hypertension control in Black communities. In the BLESSED trial, the investigators plan to recruit 1,176 adults with hypertension (approximately 28 per church) from 42 predominantly Black churches in the Greater New Orleans area. The multifaceted intervention will last for 18 months, followed by a post-intervention follow-up visit at 24 months. The BLESSED trial aims to generate evidence regarding the effectiveness, implementation, and sustainability of this CHW-led church-based multifaceted intervention in eliminating hypertension disparities in the United States (US) general population.

    Behavioral

    The recommended evidence-based interventions include therapeutic lifestyle change and medical treatment of hypertension

Trial outcomes

Primary outcomes

1

Difference in mean change of systolic blood pressure

Difference in mean change of systolic blood pressure from baseline to 18 months between intervention and control groups

Time frame
Measured from baseline to 18 months
2

Implementation fidelity summary score

The fidelity summary score is composed of the following key implementation strategy components: proportion of assigned health education sessions attended in all participants, proportion of assigned discussion sessions attended in all participants, proportion of recommended minutes of physical activity completed in all participants, proportion of days per week that fruits/vegetables are eaten as recommended in all participants, proportion of recommended home blood pressure (BP) monitoring completed in patients with hypertension, proportion of required provider visits attended in all patients, and proportion of antihypertensive medications taken in patients with hypertension. The score ranged from zero to six with a higher score indicates greater fidelity.

Time frame
Measured at 6, 12, and 18 months

Secondary outcomes

1

Difference in the proportion of patients with controlled BP between intervention and control groups

Difference in the proportion of patients with controlled BP (\<130/80 mm Hg) between intervention and control groups at 18 months

Time frame
Measured from baseline to 18 months
2

Difference in mean change of diastolic BP

Difference in mean change of diastolic BP (DBP) from baseline to 18 months between intervention and control groups

Time frame
Measured from baseline to 18 months
3

Side effects of medications and adverse events

Change in side effects of medications and adverse events from baseline to 18 months

Time frame
Measured from baseline to 18 months
4

Cost-effectiveness

Cost-effectiveness assessed as incremental direct costs per additional percentage of hypertension control

Time frame
Measured from baseline to 18 months

Other outcomes

1

Change in quality of life

The difference in QoL between the two arms over 18 months. QoL will be assessed using the SF-12 questionnaire. Scores range from 0 to 100, with higher scores indicating better physical and mental health functioning.

Time frame
Measured from baseline to 18 months
