BackgroundRecovery from major surgery can be difficult to predict given the many factors involved in treating disease and restoring preoperative function. Postoperative recovery metrics such as length of stay, complications, and mortality are typically described. However, large data quantities for patient-reported recovery are scarce. In this retrospective study, we aimed to describe the multidimensional recovery trajectory of patients undergoing major abdominal surgery 4-8 weeks after surgery and explore factors related to incomplete overall recovery.MethodsWe retrospectively analysed pooled cohort data of adults undergoing elective major abdominal surgery between 2018 and 2024 across three tertiary-level hospitals. Recovery was measured at postoperative days 1, 3, 7, 14, weeks 4-8, and 3 months using the Postoperative Quality of Recovery Scale (PostopQRS). Physiological, nociceptive, emotive, activities of daily living (ADL), and cognitive domains were assessed, with recovery defined as a return to, or improvement of, preoperative baseline levels. Overall recovery was defined as recovery in all domains. Length of stay was assessed for patients who recovered overall, or did not recover, at postoperative weeks 4-8.ResultsSix hundred and fifty-three patients were included, with mean (SD) age of 57.8 (14.4) years. Of these, 36% were aged ≥65 years and 58% were male. The incidence of overall recovery at postoperative week 4-8 was 42%. Domain-level recovery at postoperative weeks 4-8 was 63% for nociception, 81% for emotion, 82% for ADLs, and 83% for cognition. Patients failing to achieve overall recovery at weeks 4-8 had longer mean (SD) lengths of stay compared to those who recovered (11.3 (10.3) vs. 7.3 (7.1) days, p < .001).ConclusionsThe incidence of overall recovery at postoperative week 4-8 was 42%. Patients with incomplete overall recovery had longer lengths of stay. Multidimensional strategies to improve the recovery trajectory warrant further investigation.Editorial CommentMajor surgical procedures are often followed by a lengthy and difficult recovery period. Traditional measures such as mortality and complications are usually analysed, but this 653-patient study investigated patient-reported recovery scores after major abdominal surgery. Novel findings include that only 42% of patients have recovered fully in all recovery domains at weeks 4-8, and these patients also had longer hospital stays. Preoperative risk factors were analysed for associations with recovery trajectories.© 2025 The Author(s).
