Abstract

The aim of this study was to define a threshold of minimal clinically important improvement (MCII) for interpreting patient condition following video-assisted thoracoscopic surgery (VATS).Patients undergoing VATS were recruited for this multicenter, prospective, observational cohort study. Symptoms were measured using the MD Anderson Symptom Inventory-Lung Cancer Module perioperatively. To define MCIIs, we first identified index symptoms, defined as the most severe symptoms showing the largest reduction from day 1 post-surgery to discharge. MCIIs for each index symptom were then obtained via an anchor-based approach. Symptom recovery was defined as an MCII after post-surgery day 1. Cox regression models were used to identify risk factors for unrecovered index symptoms.Using 366 patients, we identified pain and fatigue as index symptoms after VATS. MCII was defined as a 30% reduction in pain or fatigue. At discharge, 22.6% of patients had not recovered from pain and 22.4% had not recovered from fatigue. Cox models found that risk factors for unrecovered pain were Charlson Comorbidity Index score ≥1 (hazard ratio [HR] 1.36, 95% confidence interval [CI] 1.04-1.77; p = 0.02) and preoperative neoadjuvant therapy (HR 2.78, 95% CI 1.13-6.83; p = 0.02). Malignancy was a risk factor for unrecovered fatigue (HR 1.47, 95% CI 1.02-2.13; p = 0.04).Pain and fatigue can be used as index measures for symptom recovery in patients following VATS. A 30% MCII represented meaningful recovery after VATS and could identify patients who may need extensive care after discharge.
