Impact of Patient-Reported Outcome Monitoring via Recovery Tracker on Post-Discharge Outcomes After Colorectal Surgery: A Comparative Analysis Before and After Implementation

Background: Remote symptom monitoring via electronic platforms may identify patients at risk for unplanned acute care visits after surgery. Since 2016, the Memorial Sloan Kettering Cancer Center (MSKCC) has employed the Recovery Tracker (RT), a patient-reported outcome (PRO) system, for symptom monitoring after ambulatory procedures. In 2021, RT was extended to patients undergoing inpatient colorectal surgery. Objective: To evaluate the impact of RT implementation on urgent care utilization and readmission rates in patients undergoing elective inpatient colorectal surgery and to determine whether patient engagement with RT influences these outcomes. Methods: In this retrospective observational study at MSKCC, we compared patients undergoing elective colorectal surgery during the RT implementation period (March 2021–December 2022) to a historical control cohort (February 2019–February 2020). The primary outcome was a potentially unnecessary urgent care center (UCC) visits—defined as a visit not requiring inpatient admission. Secondary outcomes included 30-day readmission and survey engagement. Multivariable logistic regression was used for adjusted comparisons. Results: A total of 1941 patients in the RT cohort and 1206 in the control group met the inclusion criteria. The RT cohort had higher rates of UCC visits without admission (4.43% vs. 1.6%) and 30-day readmissions (9.74% vs. 6.88%). RT period surgery was independently associated with increased odds of UCC visits (OR 2.80, 95% CI 1.71–4.58, p < 0.0001) and readmissions (OR 1.43, 95% CI 1.09–1.88, p = 0.0098). Notably, RT users who completed at least one survey (70.2%) had significantly lower odds of readmission (OR 0.56, 95% CI 0.41–0.77, p = 0.0003) compared to non-responders. Discussion: Engagement with the RT system was associated with a 44% reduction in readmission risk, identifying non-responders as a vulnerable subgroup. While the overall rates of post-discharge care utilization increased after RT implementation, active participation in PRO reporting emerged as a protective factor. Conclusions: These findings highlight the need for strategies to promote engagement and support patients less likely to interact with remote monitoring tools. Non-response may signal barriers such as technological challenges or increased vulnerability, warranting proactive engagement strategies.
