The Nueva Ecija Cardiovascular Risk Experiment (NECVaRE)

15 avril 2019 mis à jour par: Joseph J. Capuno, UPecon Foundation, Inc.

The Nueva Ecija Cardiovascular Risk Experiment: An Evaluation of the Impact of Risk Information and Screening on Primary Prevention of Cardiovascular Disease

This study seeks to assess how beliefs about health risks, specifically the risk of cardiovascular disease (CVD), affect health lifestyles and the demand for preventive care in a low-income setting. It also aims to establish the effectiveness of the Package of Essential Noncommunicable Disease Interventions in the Philippines (PhilPEN) in delivering primary prevention of CVD. To meet these objectives, the study is designed as a randomized parallel experiment with two separate, non-overlapping treatment groups and one control group. The experiment will be implemented in Nueva Ecija province, Philippines.

Aperçu de l'étude

Description détaillée

This study seeks to assess how beliefs about health risks, specifically the risk of cardiovascular disease (CVD), affect health lifestyles and the demand for preventive care in a low-income setting. It also aims to establish the effectiveness of the Package of Essential Noncommunicable Disease Interventions in the Philippines (PhilPEN) in delivering primary prevention of CVD.To realize the first objective, the investigators will measure the accuracy of beliefs about exposure to CVD risk and, subsequently, randomly provide information on personal CVD risk based on measured risk factors. This will allow assessment of the extent to which biased beliefs constrain demand for primary prevention and sustain unhealthy lifestyles. In addition, the investigators will test whether beliefs about susceptibility to CVD are responsive to the receipt of information on personal risk, and whether health behaviors and the demand for CVD screening and medication are affected by any revision of beliefs.

To meet the second objective the investigators will randomly encourage uptake of the PhilPEN program's risk screening by offering entry to a money prize lottery conditional on attending a health clinic where the program operates. The induced random variation in clinic attendance will be used to estimate the program's impact on exposure to risk factors, medication of hypertension, the predicted risk of CVD and awareness of this risk.

Meeting both objectives will allow the investigators to distinguish between scenarios. One is that PhilPEN is effective in preventing CVD of patients who access the program but its impact on population health is muted because poor information on susceptibility to CVD reduces the demand for primary prevention. Another is that even if improved information is effective in raising this demand, this will have little impact on population health through PhilPEN because of deficiencies in the operation of the program in health facilities.

Within the Nueva Ecija province, the investigators will randomly sample barangays (N=304), subsequently households (n=5019) and, finally, one person aged 40-70 within each household. At the barangay level, the investigators will randomly allocate to a treatment group receiving the lottery incentive to attend a health clinic (n=2261), another treatment group receiving information on personal CVD risk (n=497) and a control group (n=2261). A baseline survey (January-April 2018) will record data on initial health, health behavior, health knowledge, risk perceptions, risk attitudes, time preferences, health care utilization and expenditure and socioeconomic characteristics, and deliver the treatments. A follow-up survey 9-12 months later will record outcomes.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Information on CVD risk
Respondents will receive information on the predicted probability of having a heart attack or stroke within 10 years. The predictions will be obtained from the Globorisk tool (www.globorisk.org). All information will be provided within a risk perceptions module of the baseline survey. Only this module will differ across the two treatment groups (information and lottery) and the control group. Information obtained from earlier modules will be retrieved automatically and used to make predictions of CVD risk consistent with the risk factor profile of the respondent.
Respondents will be provided three types of information on CVD risks: a CVD base rate, a personalized CVD risk and an optimal CVD risk. The CVD base rate will be predicted from the respondent's age and sex only. After reporting their own chance of having a heart attack or stroke within ten years, the respondents in the treatment group will be told the risk for someone with the same age, sex, smoking status, body mass index (BMI) and blood pressure as them. Finally, a treatment group respondent will receive information on what the 10-year CVD risk would be for someone of the same age and gender who did not smoke, and had normal blood pressure and BMI.
Expérimental: Lottery Incentive
Respondents will be offered a ticket for a lottery with a money prize on condition that they visit a specific public health clinic for a checkup. There will be one prize per barangay giving each respondent a one in ten chance of winning P5000 (US$100). The prize is equivalent to approximately 14 days earnings at the regional minimum wage.
Respondents will simply be told that they can enter a lottery if they go to the specified clinic for a checkup. The health facilities will be told to conduct an assessment deemed appropriate for any particular patient that requests to be issued with a lottery ticket. No instructions will be given that the facilities should follow the PhilPEN protocol. We will evaluate whether they do implement the protocol for patients who qualify (by age if nothing else) for full risk screening.
Aucune intervention: Control
No intervention will be introduced to the participants in this arm.
