Background and Aims: Chronic post thoracotomy pain (CPTP) is a nagging complication and can affect quality of life (QOL). Studies conducted across globe have found a wide variability in the risk factors predisposing to chronic pain following thoracotomy. As no study on CPTP is available from India, we aim to detect the prevalence of CPTP, assess the predisposing factors implicated in its causation and study the impact of CPTP on QOL. Methods: After obtaining clearance from Institutional ethics committee, medical records of patients who underwent open posterolateral thoracotomy between January 2012 and December 2015 were reviewed. Data on perioperative variables, address, and contact number were collected from the patient records. All patients were mailed the Telugu translation of medical outcome study short form -36(MOS-SF-36) QOL questionnaire and were contacted telephonically to enquire about presence of CPTP and QOL. A univariate analysis was done to assess factors associated with CPTP and a multivariate logistic regression analysis was done subsequently to identify independent risk factors of CPTP. QOL indices were compared between those patients who suffered from CPTP and those who did not. Results: The prevalence of pain in our study was 40.86% (85/208). The factors implicated in the causation of CPTP were diabetes mellitus, preoperative pain, rib resection, and duration of chest tube drainage with odds ratio of 9.8, 2.6, 6.7, and 1.03, respectively. The health-related QOL showed poor scores in all domains in patients suffering from CPTP. Conclusion: The prevalence of CPTP was high. It significantly impacts health-related QOL.
