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. Trial registration Australian New Zealand Clinical Trials Registry ANZCTR 12613000664741.

This document provides an update to the recommendations for physiotherapy management for adults with coronavirus disease 2019 (COVID-19) in the acute hospital setting. It includes: physiotherapy workforce planning and preparation; a screening tool for determining requirement for physiotherapy; and recommendations for the use of physiotherapy treatments and personal protective equipment. New advice and recommendations are provided on: workload management; staff health, including vaccination; providing clinical education; personal protective equipment; interventions, including awake proning, mobilisation and rehabilitation in patients with hypoxaemia. Additionally, recommendations for recovery after COVID-19 have been added, including roles that physiotherapy can offer in the management of post-COVID syndrome. The updated guidelines are intended for use by physiotherapists and other relevant stakeholders caring for adult patients with confirmed or suspected COVID-19 in the acute care setting and beyond.

Is preoperative physiotherapy cost-effective in reducing postoperative pulmonary complications (PPC) and improving quality-adjusted life years (QALYs) after major abdominal surgery? Cost-effectiveness analysis from the hospitals' perspective within a multicentre randomised controlled trial with concealed allocation, blinded assessors and intention-to-treat analysis. Four hundred and forty-one adults awaiting elective upper abdominal surgery attending pre-anaesthetic clinics at three public hospitals in Australia and New Zealand. 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. 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. 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. 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.

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? Individual participant-level meta-analysis (n = 800) from two randomised controlled trials analysed with multivariable regression. Adults undergoing major elective abdominal surgery. 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. PPC, hospital length of stay and 12-month mortality. 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. There is strong evidence to support preoperative physiotherapy in preventing PPCs after elective abdominal surgery.

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. 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. 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. ACTRN 12615000318583.
