Efficacy of the Enhanced Recovery After Surgery program for thoracic surgery in a developing country

PURPOSE: Enhanced Recovery After Surgery (ERAS) is a strategy used to improve perioperative outcomes and reduce complications. However, data on the efficacy of ERAS in thoracic surgery in developing countries are limited. The current study aimed to validate the benefits of ERAS among patients at a single institution. METHODS: This was a retrospective study of patients who underwent pulmonary resection at Vajira Hospital, Bangkok, Thailand, between 2016 and 2020. To compare outcomes, patients were divided into the pre-ERAS group (2016–2018) and the post-ERAS group (2019–2020) using propensity score matching (1:2) with the year 2019 as the cutoff for introducing ERAS protocols at our institution. RESULTS: In total, 321 patients were included in the analysis (pre-ERAS group, n = 74; post-ERAS group, n = 247). After propensity score matching, 56 and 112 patients were classified under the pre- and post-ERAS groups, respectively. The post-ERAS group had significantly lower pain scores than the pre-ERAS group on postoperative days 1, 2, and 3, and a lower volume of intraoperative blood loss. In the multivariable analysis, the post-ERAS group had a shorter chest tube duration (mean difference = −1.62 days, 95% confidence interval = −2.65 to −0.31) and length of hospital stay (mean difference = −2.40 days, 95% confidence interval = −4.45 to −0.65) than the pre-ERAS group. CONCLUSION: The use of ERAS guidelines in pulmonary resection is beneficial. Although no significant differences were observed in postoperative complication rate, intensive care unit stay, and additional cost burden between the two groups, patients in the post-ERAS group had a shorter postoperative chest tube duration, shorter hospital stays, shorter operative time, lower postoperative pain score, and lower volume of intraoperative blood loss.
