Shortness of breath on the day of discharge: an early alert for post-discharge complications in patients undergoing lung cancer surgery

Abstract

PurposeSymptom assessment based on patient-reported outcome (PRO) can correlate with disease severity, making it a potential tool for threshold alerts of postoperative complications. This study aimed to determine whether shortness of breath (SOB) scores on the day of discharge could predict the development of post-discharge complications in patients who underwent lung cancer surgery.MethodsPatients were from a study of a dynamic perioperative rehabilitation cohort of lung cancer patients focusing on patient-reported outcomes. Patients were assessed using the Perioperative Symptom Assessment Scale for Lung surgery (PSA-Lung). Logistic regression model was used to examine the potential association between SOB on the day of discharge and complications within 3 months after discharge. The post-discharge complications were taken as the anchor variable to determine the optimal cutpoint for SOB on the day of discharge.ResultsComplications within 3 months post-discharge occurred in 71 (10.84%) of 655 patients. Logistic regression analysis revealed that being female (OR 1.764, 95% CI 1.006–3.092, P < 0.05) and having two chest tubes (OR 2.026, 95% CI 1.107–3.710, P < 0.05) were significantly associated with post-discharge complications. Additionally, the SOB score on the day of discharge (OR 1.125, 95% CI 1.012–1.250, P < 0.05) was a significant predictor. The optimal SOB cutpoint was 5 (on a scale of 0–10). Patients with an SOB score ≥ 5 at discharge experienced a lower quality of life 1 month later compared to those with SOB score<5 at discharge (73 [50–86] vs. 81 [65–91], P < 0.05).ConclusionSOB on the day of discharge may serve as an early warning sign for the timely detection of 3 month post-discharge complications.
