A community health worker intervention to improve blood pressure among Filipino Americans with hypertension: A randomized controlled trial

Summary

This intervention was designed to test the effectiveness of a Community Health Worker (CHW) intervention on hypertension-related outcomes among Filipino Americans with hypertension living in New York City from 2011-2013. A randomized controlled trial was conducted of 240 Filipino Americans with uncontrolled hypertension using CHWs to provide educational workshops and visits over a 4 month period. Findings showed that there was increased blood pressure (BP) control and improved related factors at 8-month follow-up among the participants.

Overview

Purpose of Intervention:

To improve hypertension-related outcomes among Filipino Americans living in New York City

Intervention Type:

Research-Tested — Interventions with strong methodological rigor that have demonstrated short-term or long-term positive effects on one or more targeted health outcomes to improve minority health and/or health disparities through quantitative measures; Studies have a control or comparison group and are published in a peer-review journal; No pilot, demonstration or feasibility studies.

Results

Intentions

Improve minority health or the health of other populations with health disparities (e.g. rural populations, populations with low SES)

Intervention Primary Outcome:

Blood pressure (BP) control

Intervention Secondary Outcome:

Decreased systolic blood pressure (SBP), decreased mean diastolic blood pressure (DBP), increased appointment keeping compliance

Key Findings:

The odds of BP control from baseline to 8-months for the treatment group was 3.2 times the odds of the control group in adjusted analysis (95% CI, 1.9-5.4). A greater improvement in mean SBP was seen for the treatment group compared to the control group in adjusted analysis (difference in slopes was -6.2 [95% CI, -8.4, -4.0). A greater improvement in mean DBP was seen for the treatment group compared to the control group in adjusted analysis (difference in slopes was -2.8 [95% CI, -4.3, -1.4). The intervention group saw a significant change in appointment keeping while there was no change for the control group. The intervention effect was not significant.

Statistical Method Used:

To assess changes across groups for each continuous outcome (SBP, DBP, appointment keeping), we ran generalized estimating equations (GEE) models for repeated measures over time, adjusting for study arm, time-point, the intervention effect (study arm x time-point), as well as socio-demographics and behaviors; the intervention effects were reported. For BP control, we ran GEE models using a binomial distribution, and odds ratios were produced.

Not Tested

Essential Aspects for Success:

The strong leadership role of a trusted community partner, who employed the CHWs, was essential for the success of the intervention. The community partner was able to establish a storefront community center space staffed by CHWs, which helped to address health needs in the community.
