Clinical Trial Summary

Lung cancer is the leading cause of cancer death worldwide, representing 20,55% and 14% of cancer deaths in Spain and the United States, respectively. Currently, pulmonary resection is the treatment of choice for lung cancer. However, this surgery is associated with significant complications in almost 50% of the cases, possibly delaying patient recovery and consequently increasing hospitalisation costs.

Professor Henrik Kehlet described ERAS programs at the end of the last century. His ideas were that the application of specific measures based on scientific evidence during the perioperative period of the patient could decrease the stress produced by surgical aggression. Thus, in recent years, ERAS programs have proven effective in reducing surgical complications, length of stay and hospital costs.

Over the last years, specific ERAS surgical approaches have been described for thoracic surgery. Nevertheless, there is still a lack of evidence to support ERAS programs for pulmonary resection surgery, particularly in terms of clinical results combined with minimally invasive procedures.

Our study aims to analyze the effects of the implementation of an ERAS program in patients undergoing pulmonary resection in a tertiary university hospital on the rates of complications and readmission and the length of stay.

Description:

This study analyzes the implementation of an ERAS program in a thoracic service of a third level hospital (Hospital Fundación Jiménez Díaz, Madrid, Spain). To this end, the investigators designed an ambispective cohort study, with a prospective arm of patients undergoing thoracic surgery within an ERAS program versus a retrospective arm of patients before the implementation of the protocol. Our centre's ethics committee approved our study before the start of patient recruitment, January 2018 Ref: EO071-18_FJD. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline for cohort studies.

After informed consent, the investigators included patients consecutively since the implementation, except those who refused the inclusion in the study or were under 18 years old. The investigators also asked for informed consent from the patients who were part of the retrospective cohort. For the calculation of the required sample size, the investigators assumed that the ERAS program would result in a 25% reduction in the absolute risk of suffering a surgical complication. Since the surgical complication rate for our patients in 2016 was 40%, a type-I error of 5% and a power of 80% would require 47 patients per arm.

Procedures The investigators recruited 50 patients throughout 2018 and 2019 and compared them with data from the last 50 patients in 2016, the year in which the investigators knew the surgical complication rate. The investigators followed up each patient for 30 days after surgery through hospital and primary care medical records. Demographic and comorbidity data were collected from all patients, from which the investigators calculated Charlson's comorbidity index14 for all patients.

The investigators designed our centre's ERAS program through different measures during the preoperative, intraoperative and postoperative period. During the preoperative period, the patients and their families received comprehensive multidisciplinary information about the protocol, as well as their daily goals and expected discharge date. Also, a team specialized in therapy against lung diseases taught patients pulmonary expansion exercises to be carried out until surgery was performed. Smoking cessation and nutritional screening of the patient were also part of this stage.

The patients underwent video-assisted thoracoscopic surgery (VATS), whenever possible, leaving a chest tube at the end of the surgery. All subjects received antibiotic and antithrombotic prophylaxis. Intraoperative management of patients was performed under general anaesthesia combined with regional techniques for pain control, avoiding the use of benzodiazepines and opioids. Those patients in whom thoracic epidural catheter was implemented during surgery continued its use through a patient-controlled analgesia system. Besides, a hot air system warmed the patients during surgery to maintain normothermia. Extubation was performed as soon as possible after the end of the surgery, and encouraged early removal of the urinary catheter.

From the time of extubation, the patients began oral tolerance and respiratory physiotherapy exercises. Also, the patients were allowed to walk around early. The patients were discharged when they were free of complications, without severe pain, urinary catheter or chest tube.

Outcomes The primary outcome was the number of patients with 30-day surgical complications. The investigators defined air leakage, bleeding, infection, and reintervention as surgical complications. Secondary outcome included ERAS adherence, no-surgical complications, mortality, readmission, reintervention rates, pain (defined as any level of pain that prevents early ambulation) and hospital lenght of stay. To evaluate ERAS adherence, the investigators defined seven items: VATS approach, regional analgesia, oral tolerance within 6 hours, urinary catheter removal within 24 hours, ambulation within 24 hours, respiratory physiotherapy within 24 hours and chest tube removal within 48 hours.

Statistical analysis The investigators analyzed outcomes depending on whether the patient belonged to the ERAS program or the retrospective standard cohort. The discrete and continuous variables were described as number and percentage and median (interquartile range [IQR]) and their differences analyzed using the Pearson test or the Wilcoxon rank-sum tests. Subsequently, according to the adherence rate to ERAS items (regardless of whether the patients belonged to the ERAS or the retrospective standard cohort).

The investigators performed a multivariate logistic analysis to study the association of complication rates, readmission or pain with ERAS adherence, clinical and demographic data, presenting the results in forest plots as odds ratio with 95% confidence interval. Similarly, the investigators used Cox regression for multivariate analysis of length of stay, presenting the results in forest plot as hazard ratio with 95% confidence interval. To avoid errors by multiple comparisons, the investigators calculated the respective q-value for each p-value to maintain a false discovery rate below 5%.

The investigators considered comparisons in which p-value and q-value were below .05 as being statistically significant.

Procedure:
• ERAS program
We designed our centre's ERAS program through different measures during the preoperative, intraoperative and postoperative period. This program incluided received comprehensive multidisciplinary information, daily goals and expected discharge date, explained the expansión exercises, the video-assisted thoracoscopic surgery (VATS) under general anaesthesia combined with regional techniques, leaving only one chest tube at the end of the surgery, maintain normothermia, extubation after the end of the surgery, and early removal of the urinary catheter. From the time of extubation, the patients began oral tolerance and respiratory physiotherapy exercises. Also, the patients were allowed to walk around early.
