The LIPPSMAck POP (Lung Infection Prevention Post Surgery - Major Abdominal - with Pre-Operative Physiotherapy) trial: study protocol for a multi-centre randomised controlled trial

Effect of preoperative inspiratory muscle training combined with preoperative education on postoperative pulmonary complications in high-risk patients with lung cancer: protocol for a randomised controlled trial

INTRODUCTION

Preoperative inspiratory muscle training (IMT) is recognised as an important component of the preoperative management of lung cancer, although there is limited evidence for the delivery of a home-based IMT programme combined with preoperative education. We developed a programme combining short-term home-based IMT and preoperative physiotherapy education ('the programme'). This study aims to evaluate the effectiveness of this programme in reducing postoperative pulmonary complications (PPCs) after lung cancer resection compared with standard care.

METHODS AND ANALYSIS

In this randomised controlled trial, 114 participants scheduled for lung cancer surgery at the First Affiliated Hospital of Fujian Medical University will be randomly assigned (1:1) to either receive usual care (information booklet) or usual care combined with the programme, which consist of short-term home-based IMT and preoperative physiotherapy education. The primary outcome measure will be PPCs using the Melbourne Group Score. Secondary outcomes will include health-related quality of life, maximal inspiratory pressure, 6 min walk distance, length of hospital stay, anxiety and depression levels, and hospital costs.

ETHICS AND DISSEMINATION

The study has received ethics approval from the ethics committee of the first affiliated hospital of Fujian Medical University (approval no: MRCTA, ECFAH of MFU [2021]569). Participants will be required to provide written informed consent. The results of the study will be submitted for publication in peer-reviewed journals.

Impact of an enhanced recovery after surgery program integrating cardiopulmonary rehabilitation on post-operative prognosis of patients treated with CABG: protocol of the ERAS-CaRe randomized controlled trial

BACKGROUND

Coronary artery bypass grafting is associated with a high occurrence of postoperative cardiopulmonary complications. Preliminary evidence suggested that enhanced recovery after surgery can effectively reduce the occurrence of postoperative cardiopulmonary complications. However, enhanced recovery after surgery with systematic integration of cardiopulmonary rehabilitation (ERAS-CaRe) into for Coronary artery bypass grafting has not been evaluated so far. We thus design the ERAS-CaRe randomized-controlled trial to evaluate possible superiority of embedding cardiopulmonary rehabilitation in ERAS over ERAS alone as well as to investigate effects of differential timing of cardiopulmonary rehabilitation within enhanced recovery after surgery (pre-, post-, perio-operative) on post-operative cardiopulmonary complications following Coronary artery bypass grafting surgery.

METHODS

ERAS-CaRe is a pragmatic, randomized-controlled, parallel four-arm, clinical trial. Three hundred sixty patients scheduled for Coronary artery bypass grafting in two Chinese hospitals will be grouped randomly into (i) Standard enhanced recovery after surgery or (ii) pre-operative ERAS-CaRe or (iii) post-operative ERAS-CaRe or (iv) perio-operative ERAS-CaRe. Primary outcome is the occurrence of cardiopulmonary complications at 10 days after Coronary artery bypass grafting. Secondary outcomes include the occurrence of other individual complications including cardiac, pulmonary, stroke, acute kidney injury, gastrointestinal event, ICU delirium rate, reintubation rate, early drainage tube removal rate, unplanned revascularization rate, all-cause mortality, ICU readmission rate, plasma concentration of myocardial infarction-related key biomarkers etc. DISCUSSION: The trial is designed to evaluate the hypothesis that a cardiopulmonary rehabilitation based enhanced recovery after surgery program reduces the occurrence of cardiopulmonary complications following Coronary artery bypass grafting and to determine optimal timing of cardiopulmonary rehabilitation within enhanced recovery after surgery. The project will contribute to increasing the currently limited knowledge base in the field as well as devising clinical recommendations.

The trial was registered at the Chinese Clinical Trials Registry on 25 August 2023 (ChiCTR2300075125; date recorded: 25/8/2023, https://www.chictr.org.cn/ ).

Preoperative physiotherapy prevents postoperative pulmonary complications after major abdominal surgery: a meta-analysis of individual patient data

QUESTIONS

Among patients having elective abdominal surgery, how much does preoperative physiotherapy education with breathing exercise training reduce the incidence of postoperative pulmonary complications (PPCs), hospital length of stay and 12-month mortality? How stable are the treatment effects across different PPC definitions, including pneumonia? How much do the treatment effects on PPC, hospital length of stay and mortality vary within clinically relevant subgroups?

DESIGN

Individual participant-level meta-analysis (n = 800) from two randomised controlled trials analysed with multivariable regression.

PARTICIPANTS

Adults undergoing major elective abdominal surgery.

INTERVENTIONS

Experimental participants received a single preoperative session with a physiotherapist within 4 weeks of surgery and educated on PPC prevention with breathing exercises and early mobilisation. They were taught breathing exercises and instructed to start them immediately on waking from surgery. The control group received no preoperative or postoperative physiotherapy, or early ambulation alone.

OUTCOME MEASURES

PPC, hospital length of stay and 12-month mortality.

RESULTS

Participants who received preoperative physiotherapy had 47% lower odds of developing a PPC (adjusted OR 0.53, 95% CI 0.34 to 0.85). This effect was stable regardless of PPC definition. Effects were greatest in participants who smoked, were aged ≤ 45 years, had abnormal body weight, had multiple comorbidities, or were undergoing bariatric or upper gastrointestinal surgery. Participants having operations ≤ 3 hours in duration were least responsive to preoperative physiotherapy. Participants with multiple comorbidities were more likely to have a shorter hospital stay if provided with preoperative physiotherapy (adjusted MD -3.2 days, 95% CI -6.2 to -0.3). Effects on mortality were uncertain.

CONCLUSION

There is strong evidence to support preoperative physiotherapy in preventing PPCs after elective abdominal surgery.

Effects of enhanced recovery after surgery plus pulmonary rehabilitation on complications after video-assisted lung cancer surgery: a multicentre randomised controlled trial

BACKGROUND

Lung cancer surgery is associated with a high incidence of postoperative pulmonary complications (PPCs). We evaluated whether enhanced recovery after surgery plus pulmonary rehabilitation was superior over enhanced recovery after surgery alone in reducing the incidence of postoperative PPCs and length of hospital stay.

METHODS

In this pragmatic multicentre, randomised controlled, parallel-group clinical trial, eligible patients scheduled for video-assisted lung cancer surgery were randomly assigned (1:1) to either a newly developed programme that integrated preoperative and postoperative pulmonary rehabilitation components into a generic thoracic enhanced recovery after surgery pathway, or routine thoracic enhanced recovery after surgery. Primary outcome was the overall occurrence of PPCs within 2 weeks after surgery. Secondary outcomes were the occurrence of specific complications, time to removal of chest drain, and length of hospital stay (LOS).

RESULTS

Of 428 patients scheduled for lung cancer surgery, 374 were randomised with 187 allocated to the experimental programme and 187 to control. Incidence of PPCs at 14 Days was 18.7% (35/187) in the experimental group and 33.2% (62/187) in the control group (intention-to-treat, unadjusted HR 0.524, 95% CI 0.347 to 0.792, p=0.002). Particularly, significant risk reduction was observed regarding pleural effusion, pneumonia and atelectasis. Time to removal of chest drain and LOS were not significantly reduced in the experimental group.

CONCLUSIONS

Adding pulmonary rehabilitation to enhanced recovery after surgery appears to be effective in reducing the incidence of PPCs, but not LOS. Standard integration of pulmonary rehabilitation into thoracic enhanced recovery after surgery is a promising approach to PPC prophylaxis.

Intensive physical therapy after emergency laparotomy: Pilot phase of the Incidence of Complications following Emergency Abdominal surgery Get Exercising randomized controlled trial

BACKGROUND

Postoperative pneumonia and delayed physical recovery are significant problems after emergency laparotomy. No randomized controlled trial has assessed the feasibility, safety, or effectiveness of intensive postoperative physical therapy in this high-risk acute population.

METHODS

The internal pilot phase of the Incidence of Complications after Emergency Abdominal Surgery: Get Exercising (ICEAGE) trial was a prospective, randomized controlled trial that evaluated the feasibility, safety, and clinical trial processes of providing intensive physical therapy immediately following emergency laparotomy. Fifty consecutive patients were recruited at the principal participating hospital and randomly assigned to standard-care or intensive physical therapy of twice daily coached breathing exercises for 2 days and 30 minutes of daily supervised rehabilitation over the first 5 postoperative days.

RESULTS

Interventions were provided exactly as per protocol in 35% (78 of 221 patients) of planned treatment sessions. Main barriers to protocol delivery were physical therapist unavailability on weekends (59 of 221 patients [27%]), awaiting patient consent (18 of 99 patients [18%]), and patient fatigue (26 of 221 patients [12%]). Despite inhibitors to treatment delivery, the intervention group still received twice as many breathing exercise sessions and four times the amount of physical therapy over the first 5 postoperative days (23 minutes [interquartile range, 12-29 minutes] vs. 86 minutes [interquartile range, 53-121 minutes]; p < 0.001). One adverse event was reported from 78 rehabilitation sessions (1.3%), which resolved fully on cessation of activity without escalation of medical care.

CONCLUSION

Intensive postoperative physical therapy can be delivered safely and successfully to patients in the first week after emergency laparotomy. The ICEAGE trial protocol resulted in intervention group participants receiving more coached breathing exercises and spending significantly more time physically active over the first 5 days after surgery compared with standard care. It was therefore recommended to progress into the multicenter phase of ICEAGE to definitively test the effect of intensive physical therapy to prevent pneumonia and improve physical recovery after emergency laparotomy.

Effects of the breath stacking technique after upper abdominal surgery: a randomized clinical trial

OBJECTIVE

To evaluate the effect of the association of the breath stacking (BS) technique associated with routine physiotherapy on pulmonary function, lung volumes, maximum respiratory pressures, vital signs, peripheral oxygenation, thoracoabdominal mobility, and pain in the surgical incision in patients submitted to upper abdominal surgery during the postoperative period, as well as to analyze BS safety.

METHODS

This was a randomized clinical trial involving 34 patients divided into a control group (CG; n = 16), who underwent conventional physiotherapy only, and the BS group (BSG; n = 18), who underwent conventional physiotherapy and BS. Both groups performed two daily sessions from postoperative day 2 until hospital discharge. The primary outcomes were FVC and Vt. The safety of BS was assessed by the incidence of gastrointestinal, hemodynamic, and respiratory repercussions.

RESULTS

Although FVC significantly increased at hospital discharge in both groups, the effect was greater on the BSG. Significant increases in FEV1, FEV1/FVC ratio, PEF, and FEF25-75% occurred only in the BSG. There were also significant increases in Ve and Vt in the BSG, but not when compared with the CG values at discharge. MIP and MEP significantly increased in both groups, with a greater effect on the BSG. There was a significant decrease in RR, as well as a significant increase in SpO2 only in the BSG. SpO2 acutely increased after BS; however, no changes were observed in the degree of dyspnea, vital signs, or signs of respiratory distress, and no gastrointestinal and hemodynamic repercussions were observed.

CONCLUSIONS

BS has proven to be safe and effective for recovering pulmonary function; improving lung volumes, maximum respiratory pressures, and peripheral oxygenation; and reducing respiratory work during the postoperative period after upper abdominal surgery.

Effects of preoperative physiotherapy on signs and symptoms of pulmonary collapse and infection after major abdominal surgery: secondary analysis of the LIPPSMAck-POP multicentre randomised controlled trial

Background

Preoperative education and breathing exercise training by a physiotherapist minimises pulmonary complications after abdominal surgery. Effects on specific clinical outcomes such as antibiotic prescriptions, chest imaging, sputum cultures, oxygen requirements, and diagnostic coding are unknown.

Methods

This post hoc analysis of prospectively collected data within a double-blinded, multicentre, randomised controlled trial involving 432 participants having major abdominal surgery explored effects of preoperative education and breathing exercise training with a physiotherapist on postoperative antibiotic prescriptions, hypoxemia, sputum cultures, chest imaging, auscultation, leukocytosis, pyrexia, oxygen therapy, and diagnostic coding, compared to a control group who received a booklet alone. All participants received standardised postoperative early ambulation. Outcomes were assessed daily for 14 postoperative days. Analyses were intention-to-treat using adjusted generalised multivariate linear regression.

Results

Preoperative physiotherapy was associated with fewer antibiotic prescriptions specific for a respiratory infection (RR 0.52; 95% CI 0.31 to 0.85, p = 0.01), less purulent sputum on the third and fourth postoperative days (RR 0.50; 95% CI 0.34 to 0.73, p = 0.01), fewer positive sputum cultures from the third to fifth postoperative day (RR 0.17; 95% CI 0.04 to 0.77, p = 0.01), and less oxygen therapy requirements (RR 0.49; 95% CI 0.31 to 0.78, p = 0.002). Treatment effects were specific to respiratory clinical coding domains.

Conclusions

Preoperative physiotherapy prevents postoperative pulmonary complications and is associated with the minimisation of signs and symptoms of pulmonary collapse/consolidation and airway infection and specifically results in reduced oxygen therapy requirements and antibiotic prescriptions.

Physiotherapy Practice for Management of Patients Undergoing Upper Abdominal Surgery in United Arab Emirates - A National Survey

BACKGROUND

The main goal of physiotherapy post-upper abdominal surgery (UAS) is to expedite recovery from the surgery by avoiding or remediating postoperative pulmonary complications (PPCs) and offering physical rehabilitation to ease the process of returning to premorbid status. The present study aimed to survey physiotherapists in the United Arab Emirates (UAE) about their clinical practice in the assessment and management of patients having upper abdominal surgery.

METHODS

The current study adopted a novel anonymous online survey to explore the current practice among physiotherapists in the UAE. The Research Ethics Committee approved the study, and a questionnaire was borrowed from a previous study with similar objectives completed in Australia. The questionnaire had 51 questions cutting across 7 sections that investigated the assessment tools and interventions and explored current practice amongst physiotherapists treating patients following abdominal surgery in UAE hospitals.

RESULTS

A survey of 42 post-UAS physiotherapy practitioners across the UAE was conducted with a 42% response rate and 57.5% completion rate. The mean age of physiotherapists who were working in the UAE is 35 years, most of whom have more than five years of general ward experience. Most patients were not seen on day zero (day of surgery). Respondents in the UAE are almost universally preferred prescribing deep breathing exercises, incentive spirometry (IS), mobility from the bedside, and education as their primary intervention either "often" or "always" in the consecutive days post-UAS. Spo2, visual analog scale, respiratory rate and fatigue are used as key outcome measures.

CONCLUSION

Research work on physiotherapy postoperatively has shown demonstrated prominence of mobilization but is not yet reflected in current practice among physiotherapists caring for post-UAS cohorts in the UAE. The vast difference in the choice of screening tools preferred by physiotherapists in diagnosing high-risk patients postoperatively reflects a lack of corroborating evidence available to physiotherapists.

The Protective Effects of Butorphanol on Pulmonary Function of Patients with Obesity Undergoing Laparoscopic Bariatric Surgery: a Double-Blind Randomized Controlled Trial

BACKGROUND

Obesity is a risk factor for postoperative pulmonary complications (PPCs). Recent studies have reported the pulmonary protective role of the kappa opioid receptor (KOR). Butorphanol is a narcotic with strong KOR agonist action, and the role in pulmonary protection is uncertain. Here, we hypothesized that butorphanol exerts protective effects on pulmonary function in patients with obesity undergoing laparoscopic bariatric surgery.

METHODS

Patients with a body mass index ≥ 30 kg/m² scheduled for laparoscopic bariatric surgery were randomized to receive butorphanol or normal saline. Butorphanol was administered as an initial loading dose of 10 μg/kg at 5 min before induction followed by 5 μg/(kg h) during surgery. The primary outcome was arterial-alveolar oxygen tension ratio (a/A ratio). Secondary outcomes included other pulmonary variables, biomarkers reflecting pulmonary injury, and incidence of PPCs within 7 days after surgery.

RESULTS

Patients in the butorphanol group had a significantly higher a/A ratio at 1 h after the operation began (68 ± 7 vs. 55 ± 8, P < 0.001), end of the operation (73 ± 8 vs. 59 ± 7, P < 0.001), and 1 h after extubation (83 ± 9 vs. 70 ± 5, P < 0.001) compared with those in the control group. In addition, in the butorphanol group, dead space to tidal volume ratios were significantly lower than those in the control group at the same time points (all P < 0.001). In the control group, the levels of biomarkers reflecting pulmonary injury were significantly higher than those in the butorphanol group at 3 h, 6 h, 12 h, and 24 h postoperatively (P < 0.001). The incidence of PPCs was similar in both groups.

CONCLUSION

Butorphanol administration protected pulmonary function by improving oxygenation and reducing dead space ventilation in patients with obesity undergoing laparoscopic bariatric surgery. Butorphanol may therefore provide clinical benefits in patients with obesity.

Preserving pulmonary function and functional capacity in children undergoing open abdominal surgery: A one group pretest-posttest, quasiexperimental pilot trial

PURPOSE

The aim of this trial was to determine the effects of Preoperative physiotherapy education (POPE) and Postoperative physiotherapy (POP) maintaining pulmonary function and functional capacity in children undergoing open abdominal surgery.

METHODS

A total of eight children aged, 5-17 years old posted for open abdominal surgery received POPE and POP. Spirometry, 10 m walk test (10mWT), timed up and go test (TUGT) and chest expansion were taken preoperatively and postoperatively on day one and five. Six minute walk test (6MWT), and Nine stair climbing test (9SCT) were taken preoperatively and postoperatively on day five.

RESULTS

No statistical significant difference were noted in FVC, FEV1, PEFR, FEV1/FVC Ratio, chest expansion levels and Borg scale but in TUGT, 10mWT, 6MWT and 9SCT significant difference was noted. Effect size were calculated and post hoc power analysis revealed that the power of the study is >90%.

CONCLUSION

POPE might have positive effects in preserving pulmonary function and functional capacity.

Preoperative physiotherapy is cost-effective for preventing pulmonary complications after major abdominal surgery: a health economic analysis of a multicentre randomised trial

QUESTION

Is preoperative physiotherapy cost-effective in reducing postoperative pulmonary complications (PPC) and improving quality-adjusted life years (QALYs) after major abdominal surgery?

DESIGN

Cost-effectiveness analysis from the hospitals' perspective within a multicentre randomised controlled trial with concealed allocation, blinded assessors and intention-to-treat analysis.

PARTICIPANTS

Four hundred and forty-one adults awaiting elective upper abdominal surgery attending pre-anaesthetic clinics at three public hospitals in Australia and New Zealand.

INTERVENTIONS

The experimental group received an information booklet and a 30-minute face-to-face session, involving respiratory education and breathing exercise training, with a physiotherapist. The control group received the information booklet only.

OUTCOME MEASURES

The probability of cost-effectiveness and incremental net benefits was estimated using bootstrapped incremental PPC and QALY cost-effectiveness ratios plotted on cost-effectiveness planes and associated probability curves through a range of willingness-to-pay amounts. Cost-effectiveness modelling utilised 21-day postoperative hospital cost audit data and QALYs estimated from Short Form-Six Domain health utilities and mortality to 12 months.

RESULTS

Preoperative physiotherapy had 95% probability of being cost-effective with an incremental net benefit to participating hospitals of A$4,958 (95% CI 10 to 9,197) for each PPC prevented, given that the hospitals were willing to pay $45,000 to provide the service. Cost-utility for QALY gains was less certain. Sensitivity analyses strengthened cost-effectiveness findings. Improved cost-effectiveness and QALY gains were detected when experienced physiotherapists delivered the intervention.

CONCLUSIONS

Preoperative physiotherapy aimed at preventing PPCs was highly likely to be cost-effective from the hospitals' perspective. For each PPC prevented, preoperative physiotherapy is likely to cost the hospitals less than the costs estimated to treat a PPC after surgery. Potential QALY gains require confirmation.

Does a pulmonary rehabilitation based ERAS program (PREP) affect pulmonary complication incidence, pulmonary function and quality of life after lung cancer surgery? Study protocol for a multicenter randomized controlled trial

BACKGROUND

Lung cancer surgery is associated with a high incidence of postoperative pulmonary complications (PPCs). Preliminary evidence suggests that ERAS processes can reduce overall incidence of PPCs as short- and long-term recovery improved by supporting units to adopt evidence-based care. However, the evidence is inconclusive due to insufficient high-level studies in this research field. No well-designed, adequately powered, randomized controlled trials (RCTs) have investigated the effects of pulmonary rehabilitation based ERAS program (PREP) on post-operative pulmonary complications, pulmonary function, and health related quality of life following lung cancer surgery.

METHODS

The PREP trial is a pragmatic, investigator-initiated, multi-center, randomized controlled, parallel group, clinical trial. Five hundred patients scheduled for minimally invasive pulmonary resection at six hospitals in China will be randomized with concealed allocation to receive either i) a pre-operative assessment and an information booklet or ii) a pre-operative assessment, an information booklet, plus an additional education, a 30-min pulmonary rehabilitation training session and the post-operative pulmonary rehabilitation program. The primary outcome is incidence of PPCs defined with the Melbourne Group Scale diagnostic scoring tool. Secondary outcomes include incidence of cardiopulmonary and other complications, pulmonary function, cardiopulmonary endurance, muscle strength, activity level, health-related quality of life (HRQoL), pre- and post-operative hospital length of stay (LOS), and total hospital LOS.

DISCUSSION

The PREP trial is designed to verify the hypothesis that pulmonary rehabilitation based ERAS program reduces incidence of PPCs and improves pulmonary function and HRQoL in patients following lung cancer surgery. This trial will furthermore contribute significantly to the limited knowledge about the pulmonary rehabilitation based ERAS program following lung cancer surgery, and may thereby form the basis of future recommendations in the surgical community.

Non-Invasive Positive airway Pressure thErapy to Reduce Postoperative Lung complications following Upper abdominal Surgery (NIPPER PLUS): protocol for a single-centre, pilot, randomised controlled trial

INTRODUCTION

Postoperative pulmonary complications (PPCs) are a common serious complication following upper abdominal surgery leading to significant consequences including increased mortality, hospital costs and prolonged hospitalisation. The primary objective of this study is to detect whether there is a possible signal towards PPC reduction with the use of additional intermittent non-invasive ventilation (NIV) compared with continuous high-flow nasal oxygen therapy alone following high-risk elective upper abdominal surgery. Secondary objectives are to measure feasibility of: (1) trial conduct and design and (2) physiotherapy-led NIV and a high-flow nasal oxygen therapy protocol, safety of NIV and to provide preliminary costs of care information of NIV and high-flow nasal oxygen therapy.

METHODS AND ANALYSIS

This is a single-centre, parallel group, assessor blinded, pilot, randomised trial, with 130 high-risk upper abdominal surgery patients randomly assigned via concealed allocation to either (1) usual care of continuous high-flow nasal oxygen therapy for 48 hours following extubation or (2) usual care plus five additional 30 min physiotherapy-led NIV sessions within the first two postoperative days. Both groups receive standardised preoperative physiotherapy and postoperative early ambulation. No additional respiratory physiotherapy is provided to either group. Outcome measures will assess incidence of PPC within the first 14 postoperative days, recruitment ability, physiotherapy-led NIV and high-flow nasal oxygen therapy protocol adherence, adverse events relating to NIV delivery and costs of providing a physiotherapy-led NIV and a high-flow nasal oxygen therapy service following upper abdominal surgery.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from the relevant institution and results will be published to inform future multicentre trials.

ICEAGE (Incidence of Complications following Emergency Abdominal surgery: Get Exercising): study protocol of a pragmatic, multicentre, randomised controlled trial testing physiotherapy for the prevention of complications and improved physical recovery after emergency abdominal surgery

Background

Postoperative complications and delayed physical recovery are significant problems following emergency abdominal surgery. Physiotherapy aims to aid recovery and prevent complications in the acute phase after surgery and is commonplace in most first-world hospitals. Despite ubiquitous service provision, no well-designed, adequately powered, parallel-group, randomised controlled trial has investigated the effect of physiotherapy on the incidence of respiratory complications, paralytic ileus, rate of physical recovery, ongoing need for formal sub-acute rehabilitation, hospital length of stay, health-related quality of life, and mortality following emergency abdominal surgery. We hypothesise that an enhanced physiotherapy care package of additional education, breathing exercises, and early rehabilitation prevents postoperative complications and improves physical recovery following emergency abdominal surgery compared to standard care alone.

Methods

The Incidence of Complications following Emergency Abdominal surgery: Get Exercising (ICEAGE) trial is a pragmatic, investigator-initiated, multicentre, patient- and assessor-blinded, parallel-group, active-placebo controlled randomised trial, powered for superiority. ICEAGE will compare standard care physiotherapy to an enhanced physiotherapy care package in 288 participants admitted for emergency abdominal surgery at three Australian hospitals. Participants will be randomised using concealed allocation to receive either standard care physiotherapy (education, single session of coached breathing exercises, and daily early ambulation for 15 min) or an enhanced physiotherapy care package (education, twice daily coached breathing exercises for a minimum 2 days, and 30 min of daily supervised early rehabilitation for minimum five postoperative days). The primary outcome is a respiratory complication within the first 14 postoperative hospital days assessed daily with standardised diagnostic criteria. Secondary outcomes include referral for sub-acute rehabilitation services, discharge destination, paralytic ileus, hospital length of stay and costs, intensive care unit utilisation, 90-day patient-reported complications and health-related quality of life and physical capacity, and mortality at 30 days and at 1 year following surgery.

Discussion

The morbidity, mortality, and fiscal burdens following emergency abdominal surgery are some of the worst within surgery. Physiotherapy may be an effective, low-cost, minimal harm intervention to improve outcomes and reduce hospital utilisation following this surgery type. ICEAGE will test the benefits of this commonly provided intervention within a methodologically robust, multicentre, double-blinded, active-placebo controlled randomised trial.

Preoperative physiotherapy for the prevention of respiratory complications after upper abdominal surgery: pragmatic, double blinded, multicentre randomised controlled trial

OBJECTIVE

To assess the efficacy of a single preoperative physiotherapy session to reduce postoperative pulmonary complications (PPCs) after upper abdominal surgery.

DESIGN

Prospective, pragmatic, multicentre, patient and assessor blinded, parallel group, randomised placebo controlled superiority trial.

SETTING

Multidisciplinary preadmission clinics at three tertiary public hospitals in Australia and New Zealand.

PARTICIPANTS

441 adults aged 18 years or older who were within six weeks of elective major open upper abdominal surgery were randomly assigned through concealed allocation to receive either an information booklet (n=219; control) or preoperative physiotherapy (n=222; intervention) and followed for 12 months. 432 completed the trial.

INTERVENTIONS

Preoperatively, participants received an information booklet (control) or an additional 30 minute physiotherapy education and breathing exercise training session (intervention). Education focused on PPCs and their prevention through early ambulation and self directed breathing exercises to be initiated immediately on regaining consciousness after surgery. Postoperatively, all participants received standardised early ambulation, and no additional respiratory physiotherapy was provided.

MAIN OUTCOME MEASURES

The primary outcome was a PPC within 14 postoperative hospital days assessed daily using the Melbourne group score. Secondary outcomes were hospital acquired pneumonia, length of hospital stay, utilisation of intensive care unit services, and hospital costs. Patient reported health related quality of life, physical function, and post-discharge complications were measured at six weeks, and all cause mortality was measured to 12 months.

RESULTS

The incidence of PPCs within 14 postoperative hospital days, including hospital acquired pneumonia, was halved (adjusted hazard ratio 0.48, 95% confidence interval 0.30 to 0.75, P=0.001) in the intervention group compared with the control group, with an absolute risk reduction of 15% (95% confidence interval 7% to 22%) and a number needed to treat of 7 (95% confidence interval 5 to 14). No significant differences in other secondary outcomes were detected.

CONCLUSION

In a general population of patients listed for elective upper abdominal surgery, a 30 minute preoperative physiotherapy session provided within existing hospital multidisciplinary preadmission clinics halves the incidence of PPCs and specifically hospital acquired pneumonia. Further research is required to investigate benefits to mortality and length of stay.

Physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity: a nested mixed-methods randomised-controlled study

OBJECTIVES

To (1) assess memorability and treatment fidelity of pre-operative physiotherapy education prior to elective upper abdominal surgery and, (2) to explore patient opinions on pre-operative education.

DESIGN

Mixed-methods analysis of a convenience sample within a larger parallel-group, double-blinded, randomised controlled trial with concealed allocation and intention-to-treat analysis.

SETTING

Tertiary Australian hospital.

PARTICIPANTS

Twenty-nine patients having upper abdominal surgery attending pre-admission clinic within six-weeks of surgery.

INTERVENTION

The control group received an information booklet about preventing pulmonary complications with early ambulation and breathing exercises. The experimental group received an additional face-to-face 30-minute physiotherapy education and training session on pulmonary complications, early ambulation, and breathing exercises.

OUTCOME MEASURES

Primary outcome was proportion of participants who remembered the taught breathing exercises following surgery. Secondary outcomes were recall of information sub-items and attainment of early ambulation goals. These were measured using standardised scoring of a semi-scripted digitally-recorded interview on the 5th postoperative day, and the attainment of early ambulation goals over the first two postoperative days.

RESULTS

Experimental group participants were six-times more likely to remember the breathing exercises (95%CI 1.7 to 22) and 11-times more likely (95%CI 1.6 to 70) to report physiotherapy as the most memorable part of pre-admission clinic. Participants reported physiotherapy education content to be detailed, interesting, and of high value. Some participants reported not reading the booklet and professed a preference for face-to-face information delivery.

CONCLUSION

Face-to-face pre-operative physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity.

Physiotherapy in upper abdominal surgery - what is current practice in Australia?

Background

Upper abdominal surgery (UAS) has the potential to cause post-operative pulmonary complications (PPCs). In the absence of high-quality research regarding post-operative physiotherapy management, consensus-based best practice guidelines formulated by Hanekom et al. (2012) are available to clinicians providing recommendations for post-UAS treatment. Such best practice guidelines have recommended that physiotherapists should be using early mobilisation and respiratory intervention to minimise risk of PPCs. However, recent evidence supports the implementation of mobilisation as a standalone treatment in PPC prevention, though the diversity in literature poses questions regarding ideal current practice. This project aimed to document and report the assessment measures and interventions physiotherapists are utilising following UAS, establishing whether current management is reflective of best practice guidelines and recent evidence.

Results

An online survey was completed by 57 experienced Australian physiotherapists working with patients following UAS (35% survey response rate, 63% completion rate). On day one following UAS, when a patient’s condition is not medically limited, most physiotherapists routinely mobilise. Additionally, routine chest treatment continues to be implemented, with only 23% (n = 11/47) of physiotherapists mobilising patients without accompanying specific respiratory intervention. Variability of screening tools used to identify post-operative patients at high risk of PPC development was evident. Patient-dependent factors such as ‘fatigue’ and ‘non-compliance’ were among those identified as barriers to treatment, all influencing the commencement of treatment.

Conclusions

Physiotherapists indicated that early mobilisation away from the bedside was the preferred post-operative treatment within the UAS patient population. Many continue to perform routine respiratory interventions despite recent literature suggesting it may provide no additional benefit to preventing PPCs. Current intervention choice is reflective of guidelines [1], however, recent literature has called this into question and more research needs to be done to establish if these recommendations are the most effective at reducing PPCs. Continued research is necessary to promote translation of knowledge to ensure physiotherapists are mobilising patients day one post-UAS. Likewise, future work should focus on identification of barriers, the strategies used to overcome limitations and the creation of a reliable and validated screening tool to ensure appropriate prioritisation and allocation of physiotherapy resources within the UAS patient population.
