Konstantinidis K, et al. - Researchers sought the risk factors for 90-day hospital readmission after video-assisted thoracoscopic surgery (VATS) anatomical lung resections via retrospectively analyzing data collected from 481 patients discharged after VATS lobectomy or segmentectomy (January 2012–February 2016). Outcomes suggest a common encounter to readmission after VATS anatomical lung resections. More than one-third of readmissions occur between 30 days and 90 days from the index operation. Hospital readmissions occurred in 59 patients (12.3%). In 21% of patients with a hospital stay longer than 7 days readmission was reported. Pneumonia was noted to be the most frequent cause of readmission accounting for 26% of all readmissions. Problems related to prolonged chest drain management led to readmission of 18 patients. In six patients, readmission related to chest pain occurred. The readmission rate was 21% among 101 patients who experienced prolonged air leak compared to 11% in patients without prolonged air leak. Readmitted and non-readmitted patients were simialr in terms of 90-day mortality after the initial discharge. The only patient-related factor that was independently associated with readmission was low body mass index (<18.5 kg/m²).
