Optimization of Care and Recovery in Older Colorectal Surgery Patients: A Hybrid Effectiveness-Implementation Pilot Study Protocol

The period following discharge poses particularly high risks for older colorectal surgery patients. Nearly a quarter of these patients are readmitted within a month of discharge due to a variety of issues including medication errors, surgical complications, imbalance in fluid or nutrition, or worsening of pre-existing chronic diseases.Recognizing the complex interplay of these factors, it isa more comprehensive approach is imperative to improve post- operative patient care. Geriatrics co-management programs incorporate interdisciplinary patient management approaches and geriatric principles to improve outcomes in older surgical patients.The OSCAR program is an integrated care model developed by geriatricians in collaboration with colorectal surgeons that combines geriatrics co-management with postoperative surgical care for older colorectal surgery patients. The care transition intervention (CTI) is a well-established care transition model that focuses on four domains at discharge: 1) medication self-management, 2) the personal health record, 3) timely primary care/specialty care follow-up, and 4) knowledge of red flags that indicate a worsening in condition. CTI involves interactions with a trained transition coach, both in-person visits and phone calls over four weeks. In this study, the goal is to bridge the gap between inpatient and post-discharge phases and mitigate the risk of hospital readmissions through adaptation and combination of the core components of a geriatric surgery core co-management (OSCAR) program with the core components of a care transition (CTI) program by applying an implementation research approach. By customizing OSCAR co-management model with the CTI intervention model, the investigators will leverage their strengths and, efficiently address the unique requirements of both patients and the healthcare environment. The investigators will conduct a pilot feasibility hybrid type I implementation effectiveness trial of OSCAR-S.
