BackgroundChronic postsurgical pain (CPSP) is a common complication after many surgical procedures, including cardiac surgery. The prevalence of CPSP after cardiac surgery ranges from 9.5% to 56%. Most studies on CPSP after cardiac surgery are retrospective and long-term prospective studies are scarce. The aim of this study was to follow CPSP and health-related quality of life (HRQOL) prospectively in a cohort of patients, emphasizing the prevalence from 12 months to 5 years.MethodsA total of 534 patients (23% ≥75 years, 67% men) were consecutively included before surgery. Study-specific questionnaires and the Brief Pain Inventory (BPI) were used to measure CPSP at baseline, 12 months and 5-year follow-up. Short-Form Health Survey (SF-36) was used to measure HRQOL.ResultsAmong 458 patients who were alive after 5 years, 82% responded (n = 373). The majority, 89.8% (335/373), did not report CPSP, neither 12 months nor 5 years after surgery. Among the 38 patients who reported CPSP after 12 months, 24 (63%) patients did not report CPSP after 5 years. The overall prevalence of CPSP after 5 years was 3.8% (14/373). Patients reporting CPSP and resolved CPSP had lower scores on HRQOL and more pain preoperatively than patients who did not report CPSP.ConclusionsThe prevalence of CPSP was lower in this study than previously reported. Among the patients reporting CPSP at 12 months, 63% did not report CPSP after 5 years. Hence, the observed decline in CPSP is in line with studies evaluating CPSP in noncardiac surgery.SignificanceThe prevalence of chronic postsurgical pain (CPSP) at 5 years after surgery of 3.8% is lower than previously reported. The majority of patients reporting CPSP after 12 months did not report CPSP after 5 years.© 2016 European Pain Federation - EFIC®.
