Moderate and High Cardiovascular Risk Clinical Trial
Official title:
Effectiveness of Financial Incentives and Text Messages to Improve Health Care of Vulnerable Population With Moderate and High Cardiovascular Risk in Argentina: A Randomized Cluster Trial
Cardiovascular diseases are increasing throughout the developing world and are the cause of
almost 16.7 million deaths each year, of which 80% occur in low and middle-income countries.
As more than three fourth of the global burden of cardiometabolic diseases are related to
risk factors connected with lifestyles or behaviors, such as smoking, unhealthy eating, low
physical activity, and harmful consumption of alcohol. This burden could be dramatically
reduced by changing individual behaviors. This study is focused on interventions that are
aimed to improve the adherence to treatment in cardiovascular disease (hypertension), based
on a Behavioral Economics approach. Most of public policies targeted to tackle NCDs utilize a
rational economic model of behavior. Behavioral economics, by using insights from cognitive
psychology and other social sciences, has drawn a lot of attention for its potential to
increase healthy behaviors. Interventions informed by BE principles seek to rearrange the
social or physical environment in such a way to 'nudge' people towards healthier choices and
behaviors.
Main objective: to assess whether the implementation of two strategies based on behavioral
economics, that include the use of a financial incentive scheme and specific framing to
beneficiaries (i.e. mobile health interventions), increase the referral, evaluation and
follow-up of people with moderate and high cardiovascular risk in the public health network,
compared to the usual strategy.
Design: A cluster-randomized pragmatic clinical trial will be performed. The randomization
unit will be the Community Health Centers (CHC) and the intervention groups (2 arms) or
control will be assigned to 9 health centers in total (3 CHC per arm).
Population: This RCT is going to be conducted in selected CHC of Salta. Nine CHC will be
selected, which will be randomized: 3 centers to the control, 3 centers to framing
intervention with messages and 3 centers to the intervention with incentives.
A total of 900 patients ≥ 40 years, without health coverage and with a 10-year cardiovascular
risk ≥ 10% will participate in this study.
Follow up: 3 month
