Preoperative exercise therapy in lung surgery patients: A systematic review

Exercise prehabilitation in elective intra-cavity surgery: A role within the ERAS pathway? A narrative review

The Enhanced Recovery after Surgery (ERAS) model integrates several elements of perioperative care into a standardised clinical pathway for surgical patients. ERAS programmes aim to reduce the rate of complications, improve surgical recovery, and limit postoperative length of hospital stay (LOHS). One area of growing interest that is not currently included within ERAS protocols is the use of exercise prehabilitation (PREHAB) interventions. PREHAB refers to the systematic process of improving functional capacity of the patient to withstand the upcoming physiological stress of surgery. A number of recent systematic reviews have examined the role of PREHAB prior to elective intra-cavity surgery. However, the results have been conflicting and a definitive conclusion has not been obtained. Furthermore, a summary of the research area focussing exclusively on the therapeutic potential of exercise prior to intra-cavity surgery is yet to be undertaken. Clarification is required to better inform perioperative care and advance the research field. Therefore, this "review of reviews" provides a critical overview of currently available evidence on the effect of exercise PREHAB in patients undergoing i) coronary artery bypass graft surgery (CABG), ii) lung resection surgery, and iii) gastrointestinal and colorectal surgery. We discuss the findings of systematic reviews and meta-analyses and supplement these with recently published clinical trials. This article summarises the research findings and identifies pertinent gaps in the research area that warrant further investigation. Finally, studies are conceptually synthesised to discuss the feasibility of PREHAB in clinical practice and its potential role within the ERAS pathway.

Impact of prehabilitation on morbidity and mortality after pulmonary lobectomy by minimally invasive surgery: a cohort study

Background

Thoracic surgery is currently the optimal treatment for non-small cell lung cancer (NSCLC). However, it may be responsible for numerous postoperative complications and is often used in patients with multi co morbidities. In recent years, the optimization of a patient's physical capacity before surgery has been the subject of several studies. The objective of this study was to determine whether participation in a prehabilitation program would improve outcomes after surgery and lower morbidity according to the Clavien-Dindo classification.

Methods

This retrospective cohort study was performed between 1st January 2014 and 31st January 2016 at Rouen University Hospital. All adult patients with NSCLC (IIIa or <) who had pulmonary lobectomy by minimally invasive surgery and cardiopulmonary exercise testing [CPET (VO2max ≤20 mL/min/kg)] were included.

Results

The cohort included 38 patients. Two groups were formed: one group with prehabilitation (n=19) and one group without prehabilitation (n=19). Four patients were not included leaving 34 patients for the final analysis. Most patients with a Clavien-Dindo grade of ≤2 had received prehabilitation compared to patients who had not received prehabilitation, respectively 17/19 vs. 8/15; P=0.0252. Patients who had received prehabilitation had fewer postoperative complications than patients who had not received prehabilitation, respectively 8/19 vs. 12/15; P=0.0382.

Conclusions

We have shown that prehabilitation has a positive impact on the occurrence and severity of postoperative complications after pulmonary lobectomy by minimally invasive surgery. Further studies conducted in larger populations are warranted to confirm these results.

Inspiratory muscle training is effective to reduce postoperative pulmonary complications and length of hospital stay: a systematic review and meta-analysis

PURPOSE

This study systematically review and meta-analyse the effectiveness of inspiratory muscle training (IMT) to reduce postoperative pulmonary complications (PPC) and length of hospital stay (LOS), both in the preoperative and/or postoperative periods of cardiac, pulmonary, and abdominal surgical patients. Sensitive analysis was performed to examine which patients benefit more from IMT according to methodological features (quality of studies and sample size), patient's characteristics (pulmonary risk stratification, age, and body mass index), type of surgery, period of training, and training protocols (training doses and level of supervision).

METHODS

The literature search was made in the electronic databases PubMed®, EBSCO, Web of Science^®, PEDro and Scopus^®. Only randomized controlled trials were included. Data extraction, quality assessment and meta-analysis were performed.

RESULTS

We included 17 randomized controlled trials in the systematic review, of which, 12 were included for the PPC meta-analysis and 11 for the LOS meta-analysis. IMT significantly reduced the risk of PPC (Risk Ratio (RR) = 0.50, 95%CI: 0.39, 0.64, I²=0.0%), and a decrease in LOS (Mean Difference = -1.41, 95%CI: -2.07, -0.75, I² = 0.0%).

CONCLUSION

IMT is effective to reduce PPC and LOS in patients undergoing surgery. Implications for Rehabilitation Physiotherapy interventions with inspiratory muscle training (IMT) are effective to reduce postoperative pulmonary complications (PPC) and length of hospital stay (LOS) after major surgery, and should start preoperatively. Rehabilitation with IMT is beneficial at all ages and risk levels, but older and high-risk patients benefit more, as well as pulmonary surgery patients. IMT is more effective if it is supervised, and prescription target at least two-week period, sessions with more than 15 minutes, with imposed load increment, and adding other exercise modes.

Safety and efficacy of enhanced recovery after surgery (ERAS) programs in patients undergoing hepatectomy: A prospective randomized controlled trial

BACKGROUND AND AIM

Enhanced recovery after surgery (ERAS) programs, following a variety of perioperative treatments with evidence-based medical evidence, has indicated its validity to accelerate rehabilitation in a wide variety of surgical procedures. This randomized controlled trial (RCT) study was implemented to verify the safety and efficacy of the perioperative effects in patients undergoing hepatectomy with ERAS or with conventional surgery (CS).

METHODS

From August 2016 to November 2017, according to the inclusion criteria, 160 patients with liver diseases were suitable for participating in this experiment. Patients before liver resection were randomized into ERAS group (n = 80) and CS group (n = 80), and then the outcome measures were compared between the two groups.

RESULTS

Enhanced recovery after surgery group had significantly less complications than CS group (P = .009). Compared with CS group, patients in ERAS group had low peak of WBCs in postoperative day (POD1), ALT in POD1 and POD3 (P < .05), high value of ALB in POD3 and POD5 (P < .05), less pain and higher patient satisfaction (P < .001), earlier exhaust, oral feeding, ambulation and extubation time (P < .05),and also had less hospital stay and cost (P < .001). There were no significant differences in readmission rate (<30 days) between two groups (P = .772).

CONCLUSIONS

Enhanced recovery after surgery programs applied to patients undergoing hepatectomy can safely and effectively relieve stress response, reduce the incidence of complications, improve patient satisfaction, accelerate patient recovery, reduce financial burden, and bring economic benefits.

A comprehensive protocol for physiokinesis therapy and enhanced recovery after surgery in patients undergoing video-assisted thoracoscopic surgery lobectomy

Background

Video-assisted thoracoscopic surgery (VATS) lobectomy has recently been adopted as the gold standard surgical option for the treatment of early stage non-small cell lung cancer. Enhanced recovery after surgery (ERAS) is being progressively adopted in thoracic surgery to improve the postoperative outcomes. Even if the benefits of ERAS are universally accepted, to date a standardized and uniform approach has not been described in the medical literature. The Italian VATS group has recently proposed to include in the VATS lobectomy database a structured protocol for ERAS.

Methods

The ERAS section of the Italian VATS group is proposing a comprehensive ERAS protocol within the VATS lobectomy database, allowing the prospective collection of a dedicated set of data. Separate sections of the protocol are dedicated to different topics of ERAS. This study is specifically dedicated to the section of physiokinesis therapy. The medical literature will be extensively reviewed and a physiotherapy (PT) protocol of ERAS will be presented and discussed. A seta of structured clinical pathways will also be suggested for adoption in the VATS Group database.

Discussion

Pre- and post-operative adoption of an ERAS protocol in patients undergoing VATS lobectomy may promote an improved post-operative course, a shorter hospital stay and an overall more comfortable patients' experience. The mainstays of a physiokinesis therapy ERAS protocol are patients' education, constant physical and respiratory therapy sessions, and adoption of adequate devices. Although many studies have investigated the usefulness of physical and respiratory physiokinesis therapy, a comprehensive ERAS protocol for VATS lobectomy patients has not yet been described. The proposed ERAS platform, adopted by the VATS Group database, will contribute to a prospective data collection and allow a scientific analysis of the results.

Enhanced recovery pathways in thoracic surgery: the Shanghai experience

The attempts to implement the enhanced recovery (ER) program based on multiple specialties to minimize errors and complications in addition to speeding up the patient's treatment and recovery as much as possible. In China mainland, there is no unified hospital system and there are large differences between hospitals' results and protocols. The patient length of stay rate at the Shanghai Pulmonary Hospital (very high-volume referral hospital) is 7 days and may be considered a very good result compared to international rates. Perhaps thanks to these results may be due to our belief in the importance of minimally invasive approaches, and their positive effects on the patients and conduct as routinely as possible, in addition to starting to build our ER protocols. The patient should be involved in this program since his first visit to the clinic until the day he left the hospital after undergoing the operation.

Thoracic Skeletal Muscle Is Associated With Adverse Outcomes After Lobectomy for Lung Cancer

BACKGROUND

Assessment of risk associated with lung cancer resection is primarily based on evaluation of cardiopulmonary function and remains imprecise. We investigated the relationship between thoracic muscle and early outcomes after lobectomy.

METHODS

Cross-sectional area of skeletal muscle was measured at the level of the fifth thoracic vertebra on computed tomography in 135 consecutive patients before lobectomy for lung cancer. Patients were stratified into low and high muscle groups using the sex-specific muscle median. Primary outcome was a composite of any postoperative complication as per The Society of Thoracic Surgeons General Thoracic Surgical Database. Secondary outcomes included postoperative respiratory complications, postoperative intensive care unit admission, hospital length of stay, and hospital readmission within 30 days of hospital discharge. The χ² test, adjusted multivariable regression analysis, and likelihood ratio test were performed.

RESULTS

Patients with low muscle were significantly more likely to have any postoperative complication and respiratory postoperative complications. Although postoperative intensive care unit admission was similar for low muscle and high muscle groups, low muscle patients had longer hospital length of stay and a higher rate of hospital readmission. Adjusted multivariable regression revealed the independent association of thoracic muscle with all outcomes. The likelihood ratio test suggested that thoracic muscle adds predictive capability to information captured by preoperative pulmonary function testing.

CONCLUSIONS

Low thoracic muscle is independently associated with increased postoperative complications and health care utilization among patients undergoing lobectomy for lung cancer. Evaluation of thoracic muscle may enhance risk prediction models.

Effect of an intensive 3-week preoperative home rehabilitation programme in patients with chronic obstructive pulmonary disease eligible for lung cancer surgery: a multicentre randomised controlled trial

INTRODUCTION

Surgery is the standard curative treatment for lung cancer but is only possible in patients with local tumour and preserved exercise capacity. Improving fitness before surgery can reduce postoperative complications and mortality. However, preoperative rehabilitation remains difficult to implement for several reasons. We aim to investigate the effectiveness of an intensive 3-week home-based preoperative exercise training programme on hospital discharge ability, postoperative complications and physical performance in patients with chronic obstructive pulmonary disease (COPD) who are eligible for lung cancer surgery.

METHODS AND ANALYSIS

We designed a multicentre randomised controlled trial. The randomisation sequence will be generated and managed electronically by a research manager independent of assessments or interventions. We will recruit 90 patients with COPD and a diagnosis of lung cancer from four university hospitals. The rehabilitation group (R group) will receive a standardised preoperative home exercise programme for 3 weeks, combining both high-intensity training and usual physical therapy. The R group will perform 15 training sessions over 3 weeks on a cycloergometer. A physical therapist experienced in pulmonary rehabilitation will visit the patient at home and supervise one session a week. The R group will be compared with a control group receiving preoperative usual physical therapy only. The primary outcome will be hospital discharge ability assessed with a 10-item list. Secondary outcomes will be postoperative course (complication rate and mortality) as well as pulmonary function, exercise capacity and quality of life assessed 1 month before and the day before surgery.

ETHICS AND DISSEMINATION

This protocol has been approved by the French health authority for research (2016-A00622-49) and the research ethics committee/institutional review board (AU1267). Adverse events that occur during the protocol will be reported to the principal investigator. The results will be published in an international peer-reviewed journal.

The role of physiotherapy in patients undergoing pulmonary surgery for lung cancer. A literature review

This review aims to appraise the role of physiotherapy care in patients submitted to pulmonary surgery, in preoperative, perioperative, and postoperative phases. Pulmonary surgery is the gold standard treatment for patients with lung cancer if it is completely resectable. However, the major impairments and complications induced by surgery are well known. Physiotherapy has been regularly used both in the preparation of the surgical candidates; in their functional recovery in the immediate postoperative period, and in the medium/long term but there is a lack of concise evidence-based recommendations. Therefore, the aim of this review is to appraise the literature about the role of physiotherapy interventions in patients undergoing lung surgery for lung cancer, in preoperative, perioperative, postoperative and maintenance stages, to the recovery and well-being, regardless of the extent of surgical approach. In conclusion, physiotherapy programs should be individually designed, and the goals established according to surgery timings, and according to each subject's needs. It can also be concluded that in the preoperative phase, the main goals are to avoid postoperative pulmonary complications and reduce the length of hospital stay, and the therapeutic targets are respiratory muscle training, bronchial hygiene and exercise training. For the perioperative period, breathing exercises for pulmonary expansion and bronchial hygiene, as well as early mobilization and deambulation, postural correction and shoulder range of motion activities, should be added. Finally, it can be concluded that in the postoperative phase exercise training should be maintained, and adoption of healthy life-style behaviours must be encouraged.

Preoperative exercise training for patients with non-small cell lung cancer

BACKGROUND

Surgical resection for early stage non-small cell lung cancer (NSCLC) offers the best chance of cure, but is associated with a risk of postoperative pulmonary complications (i.e. pneumonia (new infiltrate coupled with either fever (> 38º C) and purulent secretions, or fever and white cell count > 11,000), bronchopleural fistula, severe atelectasis that requires chest physiotherapy or bronchoscopy, and prolonged mechanical ventilation (> 48 hours)). It is currently unclear if preoperative exercise training, and the potential resultant improvement in exercise capacity, may also improve postoperative outcomes, such as the risk of developing postoperative pulmonary complications, the length of postoperative intercostal drainage, or the length of hospital stay.

OBJECTIVES

The primary aims of this study were to determine the effect of preoperative exercise training on postoperative outcomes, such as risk of developing a postoperative pulmonary complication, and postoperative duration of intercostal catheter use in adults scheduled to undergo lung resection for NSCLC. The secondary aims of this study were to determine the effect of preoperative exercise training on length of hospital stay, fatigue, dyspnoea, exercise capacity, lung function, and postoperative mortality.

SEARCH METHODS

We searched CENTRAL, MEDLINE (PubMed), Embase Ovid, PEDro, and SciELO on the 28^th of November 2016.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) in which study participants who were scheduled to undergo lung resection for NSCLC were allocated to receive either preoperative exercise training or no exercise training.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the studies and selected those for inclusion. We performed meta-analyses for the outcomes: risk of developing a postoperative pulmonary complication; postoperative duration of intercostal catheter; length of hospital stay; post-intervention exercise capacity (6-minute walk distance), and post-intervention forced vital capacity (FVC). Although three studies reported post-intervention forced expiratory volume in 1 second (FEV₁), we did not perform meta-analysis on this outcome due to significant statistical heterogeneity (I² = 93%) across the studies. Data were not available for fatigue or dyspnoea. One study reported no in-hospital postoperative mortality in either the exercise or the non-exercise groups.

MAIN RESULTS

We identified five RCTs involving 167 participants (mean age ranged from 54 to 72.5 years; sample size ranged from 19 to 60 participants). Overall, we found that the risk of bias in the included studies was high, and the quality of evidence for all outcomes was low. Pooled data from four studies demonstrated that preoperative exercise training reduced the risk of developing a postoperative pulmonary complication by 67% (risk ratio (RR) 0.33, 95% CI 0.17 to 0.61). The number of days patients in the exercise group needed an intercostal catheter was lower than in the non-exercise group (mean difference (MD) -3.33 days, 95% CI -5.35 to -1.30 days; two studies); postoperative length of hospital stay was also lower in the exercise group (MD -4.24 days, 95% CI -5.43 to -3.06 days; four studies). Pooled data from two studies demonstrated that compared to the non-exercise group, post-intervention 6-minute walk distance (MD 18.23 m, 95% CI 8.50 to 27.96 m), and post-intervention FVC (MD 2.97% predicted, 95% CI 1.78 to 4.16% predicted) were higher in the exercise group.

AUTHORS' CONCLUSIONS

Preoperative exercise training may reduce the risk of developing a postoperative pulmonary complication, the duration of intercostal catheter use, postoperative length of hospital stay, and improve both exercise capacity and FVC in people undergoing lung resection for NSCLC. The findings of this review should be interpreted with caution due to disparities between the studies, risk of bias, and small sample sizes. This review emphasises the need for larger RCTs.

Preoperative exercise training prevents functional decline after lung resection surgery: a randomized, single-blind controlled trial

OBJECTIVES

To investigate the effects of a preoperative pulmonary rehabilitation programme in patients with lung cancer undergoing video-assisted thoracic surgery.

DESIGN

Randomized, single-blind controlled trial.

SETTING

Teaching hospital.

SUBJECTS

Patients with suspected or confirmed lung cancer undergoing video-assisted thoracic surgery.

INTERVENTION

Participants were randomized to either a prehabilitation group or a control group. Participants in the prehabilitation group underwent a combination of moderate endurance and resistance training plus breathing exercises three to five times per week.

MAIN MEASURES

The primary outcome of the study was exercise capacity. Secondary outcomes were muscle strength (Senior Fitness Test), health-related quality of life (Short-Form 36) and the postoperative outcomes. Patients were evaluated at baseline (before randomization), presurgery (only the prehabilitation group), after surgery and three months post-operatively.

RESULTS

A total of 40 patients were randomized and 22 finished the study (10 in the prehabilitation group and 12 in the control group). Three patients were lost to follow-up at three months. After the training, there was a statistically significant improvement in exercise tolerance (+397 seconds, p = 0.0001), the physical summary component of the SF-36 (+4.4 points, p = 0.008) and muscle strength ( p < 0.01). There were no significant differences between groups after surgery. However, three months postoperatively, significant differences were found in the mean change of exercise capacity ( p = 0.005), physical summary component ( p = 0.001) and upper and lower body strength ( p = 0.045 and p = 0.002).

CONCLUSIONS

A pulmonary rehabilitation programme before video-assisted thoracic surgery seems to improve patients' preoperative condition and may prevent functional decline after surgery. Clinical Registration Number: NCT01963923 (Registration date 10/10/2013).

Short-Term Preoperative High-Intensity Interval Training in Patients Awaiting Lung Cancer Surgery: A Randomized Controlled Trial

INTRODUCTION

Impairment in aerobic fitness is a potential modifiable risk factor for postoperative complications. In this randomized controlled trial, we hypothesized that a high-intensity interval training (HIIT) program enhances cardiorespiratory fitness before lung cancer surgery and therefore reduces the risk of postoperative complications.

METHODS

Patients with operable lung cancer were randomly assigned to usual care (UC) (n = 77) or preoperative rehabilitation based on HIIT (Rehab) (n = 74). Maximal cardiopulmonary exercise testing and the 6-minute walk test were performed twice before surgery. The primary outcome measure was a composite of death and in-hospital postoperative complications.

RESULTS

The groups were well balanced in terms of patient characteristics. During the preoperative waiting period (median 25 days), the peak oxygen consumption and the 6-minute walking distance increased (median +15%, interquartile range, 25th to 75 percentile [IQR25%-75%, %] = +9% to +22%, p = 0.003 and +15%, IQR25%-75% = +8% to +28%, p < 0.001, respectively) in the Rehab group, whereas peak oxygen consumption declined in the UC group (median -8%, IQR25%-75% = -16% to 0%], p = 0.005). The primary end point did not differ significantly between the two groups: at least one postoperative complication developed in 27 of the 74 patients (35.5%) in the Rehab group and 39 of 77 patients (50.6%) in the UC group (p = 0.080). Notably, the incidence of pulmonary complications was lower in the Rehab compared with in the UC group (23% versus 44%, p = 0.018), owing to a significant reduction in atelectasis (12.2% versus 36.4%, p < 0.001), and this decrease was accompanied by a shorter length of stay in the postanesthesia care unit (median -7 hours, IQR25%-75% = -4 to -10).

CONCLUSIONS

In this randomized controlled trial, preoperative HIIT resulted in significant improvement in aerobic performances but failed to reduce early complications after lung cancer resection.

The importance of exercise in lung cancer treatment

There is emerging evidence that exercise can help in a variety of different ways for people with lung cancer. Exercise can be beneficial at any stage of the patient journey through increasing strength, endurance and decreasing emotional issues. A recovery fitness program is described and provides guidance on breathing, stretching, aerobic exercise and strength training. There are more people surviving lung cancer with services needing to cater for the varying requirements of each patient. Promoting physical activity is an important facet of health care management and collaboration between providers of services is required.

Functional and postoperative outcomes after preoperative exercise training in patients with lung cancer: a systematic review and meta-analysis

Lung cancer is the leading cause of cancer-related death worldwide. For early stages of the disease, lung resection surgery remains the best treatment with curative intent, but significant morbidity is associated, especially among patients with poor pulmonary function and cardiorespiratory fitness. In those cases, the implementation of a preoperative exercise-based intervention could optimize patient's functional status before surgery and improve postoperative outcomes and enhance recovery. The aim of this systematic review is to provide the current body of knowledge regarding the effectiveness of a preoperative exercise-based intervention on postoperative and functional outcomes in patients with lung cancer submitted to lung resection surgery. A systematic review of the literature using CINAHL, EMBASE, MEDLINE, Pubmed, PEDro and SCOPUS was undertaken in September 2015 yielding a total of 1656 references. Two independent reviewers performed the assessment of the potentially eligible records against the inclusion criteria and finally, 21 articles were included in the review. Articles were included if they examined the effects of an exercise-based intervention on at least one of the selected outcomes: pulmonary function, (functional) exercise capacity, health-related quality of life (HRQoL) and postoperative outcomes (length of stay and postoperative complications). Fourteen studies were further selected for a meta-analysis to quantify the mean effect of the intervention and generate 95% confidence intervals (CIs) using the Cochrane Review Manager 5.0.25. For two of the outcomes included (exercise capacity and HRQoL), studies showed large heterogeneity and thus, a meta-analysis was considered inappropriate. Pulmonary function (forced vital capacity and forced expiratory volume in 1 s) was significantly enhanced after the intervention [standardized mean difference (SMD) = 0.38; 95% CI 0.14, 0.63 and SMD = 0.27, 95% CI 0.11, 0.42, respectively]. In comparison with the patients in the control groups, patients in the experimental groups spent less days in the hospital (mean difference = -4.83, 95% CI -5.9, -3.76) and had a significantly reduced risk for developing postoperative complications (risk ratios = 0.45; 95% CI 0.28, 0.74). In conclusion, preoperative exercise-based training improves pulmonary function before surgery and reduces in-hospital length of stay and postoperative complications after lung resection surgery for lung cancer.

Health risk factors in the anesthesia population

STUDY OBJECTIVE

We investigated the prevalence of lifestyle risk factors in patients admitted to our preoperative assessment outpatient clinic, and compared patient self-reports and anesthetist reports of health risk factors to evaluate the patient self-image of preoperative health status.

DESIGN

Cross-sectional survey.

SETTING

The study was performed in an academic teaching hospital in Amsterdam, the Netherlands, during 3 consecutive months at the preoperative screening clinic.

PATIENTS

A total of 1227 adult patients scheduled for surgery were screened, and 1111 were included (patients being excluded where data were incomplete).

INTERVENTIONS AND MEASUREMENTS

Before health risk screening by an anesthetist, patients filled out a lifestyle risk factor questionnaire including overweight, hypertension, diabetes mellitus, smoking, physical activity, and alcohol use. These were compared with risk factors stated in the preoperative assessment report of the anesthetist.

MAIN RESULTS

The study population was aged 51 ± 17 years with a body mass index of 25.6 ± 4.7 kg/m(2). The most frequent lifestyle risk factors reported by the anesthetist were overweight and obesity (47.5%), smoking (25.3%), and hypertension (23.7%). The prevalence of no, 1, or 2 lifestyle risk factors in the preoperative assessment outpatient clinic population was, respectively, 30.1%, 35.6%, and 18.5% reported by the anesthetist and 36.4%, 36.7%, and 18.6% reported by the patients. Patients with more lifestyle risk factors were older with a higher body mass index and American Society of Anesthesiologists classification. Differences in reporting of lifestyle risk factors between patients and anesthetist occurred especially with overweight (26.5% vs 47.5%).

CONCLUSIONS

The prevalence of lifestyle risk factors in perioperative patients is high, and differences in reporting between patients and anesthetists may suggest that patients are unaware of or ignore their unhealthy state. Further studies are warranted to investigate the association between the lifestyle risk factors and outcome in the anesthesiology setting.

Enhanced recovery pathway for thoracic surgery in the UK

BACKGROUND

Enhanced recovery (ER) refers to a combination of perioperative interventions designed to minimise the impact of surgery on patients' recovery in order to reduce postoperative complications and to allow an early discharge reducing hospital costs.

METHODS

An ER protocol was established at our institution following a review of the best evidence available. We introduced a multi-disciplinary integrated perioperative pathway by engaging with every person involved, including the patients themselves. The programme was monitored using specifically-designed patients related outcome measures (PROMs).

RESULTS

One-hundred and fifty-four ER patients were compared with 171 controls from the year before ER was introduced. There was an 80% increase in same-day admissions, with a net gain of more than 300 patient bed-days. The ER group had a significantly higher number of procedures performed by video assisted thoracoscopic surgery (VATS) (ER, 32.9% vs. 9.4%, P=0.0001) and a lower rate of admission to the intensive care unit (ER, 5.8% versus 12.9%, P=0.04). Patients on the ER programme had a significantly reduced postoperative length of stay (mean ER, 5.2 vs. 11.7 days, P<0.0001). Patient satisfaction was higher in the ER group after a patient survey. The project resulted in a net saving of £214,000 for the Trust for the 2013/2014 financial year. We were also able to increase the number of patients who underwent thoracic surgery in 2013/2014 by 30% (159 patients) compared with 2012/2013.

CONCLUSIONS

The ER pathway has proven to be a safe perioperative management strategy to improve patient satisfaction and to reduce the length of hospital stay and cost after major thoracic surgery, without increasing morbidity or mortality.
