Community Health Assessment Program in the Philippines (CHAP-P)

McMaster University5,229 enrolled

Overview

This study aims to evaluate the effectiveness of the Community Health Assessment Program in the Philippines (CHAP-P), looking at the differences between communities implementing CHAP-P versus communities not implementing CHAP-P.

In this study, the investigators are evaluating the effectiveness of the CHAP-P intervention in communities of the Zamboanga Peninsula, Philippines. Specifically, the investigators are looking at the difference between hemoglobin A1c (HbA1c) levels in randomly selected residents of control communities versus those in communities implementing the CHAP-P intervention. The investigators are also looking at the differences between control and intervention communities in modifiable lifestyle risk factors for diabetes, screening rates for diabetes, rates of newly diagnosed cases of diabetes, general diabetes management, and hospital admission rates, as well as the cost effectiveness of CHAP-P. The CHAP-P intervention consists of initial and follow-up sessions where trained local volunteers (Barangay Health Workers, or BHWs) take physical measurements (blood pressure, height, weight, waist circumference) and facilitate a diabetes risk survey; based on these findings, they provide education, materials, and referrals to local health resources as needed. The participant groups in this evaluation include those that attend CHAP-P sessions, randomly selected community members that provide consent for a survey and HbA1c testing, and community members and BHWs/other Lead Local Organization staff who provide consent for focus groups and interviews.

Interventions

CHAP-P SessionsOTHER

Residents of intervention communities (barangays) aged 40+ are openly invited to attend CHAP-P sessions. At CHAP-P sessions, trained local volunteers (Barangay Health Workers, or BHWs) collect consent, measure blood pressure, collect other physical measurements, and conduct a survey to determine clients' risk of diabetes. Based on the findings, BHWs provide education and/or referrals. CHAP-P sessions are held twice a month, and clients are encouraged to continuing attending for ongoing follow-up and monitoring.

Outcomes

Primary Outcomes

HbA1c

Mean difference in HbA1c at 6 months in the intervention group compared to the control group. Measured with the A1CNow+ point-of-care device in a community location after the completion of the in-home community survey.

Time frame: Baseline, 6 months

Secondary Outcomes

Physical Activity

Mean difference in physical activity at 6 months in the intervention group compared to the control group. Measured with the International Physical Activity Questionnaire (International Physical Activity Quotient, IPAQ), included in the community survey.

Time frame: Baseline, 6 months

Medication Compliance

Mean difference in medication compliance at 6 months in the intervention group compared to the control group. Self-reported, via community survey questions.

Time frame: Baseline, 6 months

Blood Pressure

Mean difference in blood pressure at 6 months in the intervention group compared to the control group. Measured using a blood pressure device, the Microlife WatchBP Office Target.

Time frame: Baseline, 6 months

Community Residents Newly Diagnosed with Diabetes

Mean difference in number of community residents newly diagnosed with diabetes at 6 months in the intervention group compared to the control group. Numbers taken from Rural Health Unit databases

Time frame: 6 months

Hospital admission rates

Mean difference in hospital admission rates due to diabetes and diabetes-related conditions, hypertension, myocardial infarction, stroke, congestive heart failure at 6 months in the intervention group compared to the control group. Numbers taken from central Department of Health database (12 months before and 12 month after CHAP-P implementation, and divided by mid-year population estimates)
