Official title
A Randomized Trial of Nudges To Enhance Enrollment in Critical Care Research
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Difficulties enrolling patients in randomized clinical trials (RCTs) have long been recognized as a major barrier to successful evaluation of medical interventions. This is particularly problematic among intensive care unit (ICU) trials, of which more than one-third do not reach target enrollment. Under-enrollment and selective enrollment reduce RCTs' abilities to answer the research questions, thereby degrading the trials' scientific value and ethics. Current evidence suggests that financial incentives can ethically increase study enrollment, but this approach can pose large up-front costs to researchers. However, several nonmonetary behavioral interventions, or nudges, may offer novel and easily scalable approaches to increase enrollment in RCTs. The investigation team propose a 2-arm RCT in 10 ICUs at Penn to test the relative effectiveness of nudges on enrollment rates. Investigators hypothesize that a bundle of nudges during recruitment will increase enrollment rates compared to usual recruitment procedures will increase enrollment. Investigators will enroll 182 critically ill patients' surrogate decision makers(participants) to engage in recruitment procedures for a simulated RCT comparing two mechanical ventilation weaning protocols among mechanically ventilated patients. Investigators will also measure participants' assessment of risk of the simulated trial after the informed consent process. This work will provide the first empirical evidence regarding the efficacy of inexpensive, scalable nudges to potentially augment enrollment and reduce costs of future clinical trials.
