Abstract
Background: The goal of the PROPEL-IT study is to conduct an effectiveness-implementation (hybrid type 1) study to 1) test the effectiveness of a digital technology focused 24-month, patient-centered precision public health approach to weight-loss, facilitated by an electronic medical record (EMR) in Black patients with obesity and type 2 diabetes mellitus or prediabetes, and 2) better understand the external validity and context for implementation.
Methods: Patients in the Intensive Lifestyle Intervention (ILI) participate in a high-intensity behavioral intervention to facilitate weight loss through reducing dietary intake and increasing physical activity. The ILI is delivered by health coaches in the digital medicine program of a large health care organization facilitated by the patient portal of their EMR. Patients in the usual care (UC) group continue to receive routine medical care from their health care team. The primary outcome is percent weight change from baseline. Study implementation is guided by the Consolidated Framework for Implementation Research (CFIR) and the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) evaluative framework.
Results: Patient recruitment began on August 31, 2022 and was completed on January 22, 2024. During the ∼17-month recruitment period, 352 patients were recruited and randomized (176 to ILI; 176 to UC).
Conclusion: The results of this study will provide evidence on the effectiveness of a remotely delivered high-intensity weight loss program within a large health care organization, and provide important information regarding its implementation in a digital medicine setting.
期刊介绍：
Contemporary Clinical Trials is an international peer reviewed journal that publishes manuscripts pertaining to all aspects of clinical trials, including, but not limited to, design, conduct, analysis, regulation and ethics. Manuscripts submitted should appeal to a readership drawn from disciplines including medicine, biostatistics, epidemiology, computer science, management science, behavioural science, pharmaceutical science, and bioethics. Full-length papers and short communications not exceeding 1,500 words, as well as systemic reviews of clinical trials and methodologies will be published. Perspectives/commentaries on current issues and the impact of clinical trials on the practice of medicine and health policy are also welcome.
