- Interventions
- Other: SOC (standard of care)Other: POPOP (preoperative patient optimization program)
- Registration Number
- NCT04910048
- Lead Sponsor
- University of Arkansas
- Brief Summary
In this pilot study, we will test the hypothesis that a POPOP for currently ineligible UAMS orthopedic surgery patients wanting hip or knee replacement improves markers of preoperative health, ability to reach a BMI threshold \<40 kg/m2 required for surgical eligibility, and postoperative outcomes versus SOC.
- Detailed Description
After being informed about the study and potential risks, all patients giving written informed consent will be screened to determine eligibility for study entry. Patients who meet eligibility criteria will be randomized into one of two groups: Standard of Care or the POPOP (20Lighter).

- Arm && Interventions
Group Intervention Description Standard of Care SOC (standard of care) The first arm consists of UAMS standard of care (SOC), including providing a brochure with information (contact information, brief educational information) for the patient to consult with a nutritionist to help with self-directed weight loss. Intervention (POPOP) POPOP (preoperative patient optimization program) The second arm is a specified 2-month POPOP focused on weight loss administered by the external partner, 20Lighter. The program includes customized meal plans; vitamin, mineral and nutritional supplementation; and daily engagement via a smartphone app with a 20Lighter health care provider. Video conferencing appointments will occur approximately every 3 weeks. The program does not require any exercise or physical engagement but does necessitate that patients have a smartphone or tablet with Bluetooth capability, cell signal or WIFI connection. During the first 40 days the customized meal plans are adhered to, then from days 41-60 patients will transition back to a normal dietary lifestyle via a customized plan based on considerations including, food preferences, physical engagement and height. Patients who achieve a BMI below 40.0 before the end of the 60 day program may be seen sooner than 90d for follow-up appointment in the UAMS clinic.
