The incidence of PPCs remained halved (hazard ratio 0.48, 95% confidence interval 0.30 to 0.75, P=0.001) in the intervention group when adjustments were made for baseline imbalances in three of the prespecified covariates—age, respiratory comorbidity, surgical procedure (table 3, fig 2), with a number needed to treat of 7 (95% confidence interval 5 to 14). 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. This phase begins as soon as you are discharged from surgery and carries on until your tissues have healed, the swelling from surgery has dissipated and the pain associated with the surgery has mostly resolved. 2019 Jun 29;4:20190013. doi: 10.2490/prm.20190013. Non-reporting of PPC risk factors and non-standardisation of early ambulation and physiotherapy are additional confounders that limit conclusions. Despite the lower PPC baseline risk, subgroup analysis suggests that across the whole trial sample both high and low risk patients have a similar relative risk reduction of PPCs given preoperative physiotherapy education. The experienced physiotherapist provided the intervention 124 times, compared with a maximum 25 for one of the junior physiotherapists. Future studies in prophylactic interventions to prevent PPCs could consider being powered a priori to detect these small, yet arguably clinically important, differences in mortality. 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. Preoperative education and breathing exercise training alone is reported to be associated with a 75% relative risk reduction and absolute risk reduction of 20% in PPCs,1718 although this effect could be exaggerated by methodological biases of single centre trials, non-masked assessors, and low risk surgical cohorts. Given this, our cohort is closely representative of the heterogeneous population having upper abdominal surgery. 10.1016/S2213-2600(14)70228-0 Our results are important in the context of considering existing evidence for other methods to prevent PPCs. Postoperative pulmonary complications are common after major abdominal surgery. To explore variations of effect and to validate the main results, we performed further exploratory post hoc adjusted analyses of subgroup effects (experience level of preoperative physiotherapist, site, and participant age, sex, surgical category, and predicted PPC risk score) in PPCs, hospital stay, and 12 month mortality. Reeve J, Boden I (2016) The Physiotherapy Management of Patients undergoing Abdominal Surgery New Zealand Journal of Physiotherapy 44(1): 33-49. doi: 10.15619/NZJP/44.1.05 Values are numbers (percentages) unless stated otherwise, Postoperative clinical events and complications between groups. Education focused on PPCs and their prevention through early ambulation and self directed breathing exercises to be initiated immediately on regaining consciousness after surgery. Postoperative pulmonary complications (PPCs) are common in patients undergoing abdominal surgery and are responsible for the increased morbidity and mortality as well as length of hospital stay and health related cost of care. To assess the efficacy of a single preoperative physiotherapy session to reduce postoperative pulmonary complications (PPCs) after upper abdominal surgery. Background: Upper abdominal surgery (UAS) has the potential to cau se post-operative pulmonary complications (PPCs). Considering the standardisation of postoperative practice, the most plausible reason for PPC reduction in our trial is that the participants performed the breathing exercises as taught preoperatively. To establish efficacy of preoperative education alone, we standardised early mobilisation and successfully removed all postoperative chest physiotherapy modalities. Gentle manual therapy to restore joint range of motion 4. Surgery is the treatment of injuries or disorders of the body by incision or manipulation, often with the use of instruments. Primary and secondary outcomes. Additionally, despite our trial being multicentred, a large proportion of participants were recruited at a single hospital in Australia. The pre-operative assessment is an opportunity to identify co-morbidities that may lead to patient complicationsduring the anaesthetic, surgical, or post-operative period. The patients, postoperative physiotherapists, hospital staff, and statisticians were unaware of group assignment. COVID-19 is an emerging, rapidly evolving situation. Neither CCF nor the University of Tasmania have managerial authority over IKR’s work. The New Zealand site also had established enhance recovery after surgery pathways,19 unlike the two Australian sites, which could explain the difference in intravenous fluid amounts, epidural usage, and the lower PPC incidence in the control group (13.8%). No attempt was made to standardise the way medical or nursing staff encouraged participants to perform breathing exercises as this was considered unfeasible and not reflective of pragmatic ward practice.

Assessors masked to group assignment retrieved these data for all participants from government databases. As a proxy measure of compliance, a convenience sample of 29 patients was interviewed on the fifth postoperative day, with 94% of intervention participants remembering the breathing exercises compared with just 15% in those who received the booklet alone.21 We extrapolate that a threshold proportion of intervention participants implemented the acquired knowledge provided by the preoperative physiotherapists and performed deep breathing exercises immediately on regaining consciousness from surgery and continued to perform them at a dose necessary to reverse the respiratory pathophysiological changes from surgery, thus preventing PPCs. All authors revised manuscript drafts, approved the final manuscript, and contributed intellectually important content. NIH Neither CCF nor the University of Tasmania have managerial authority over IKR’s work. Data are on an intention-to-treat basis and adjusted for age, previous respiratory disease, and surgical category. It cannot be extrapolated that preoperative education would be effective with the use of interpreters, in a different social-cultural context, through different modes such as visual recordings or group sessions, or with health professionals other than physiotherapists. Preoperative physiotherapists randomly assigned consecutive participants to either intervention (information booklet plus preoperative physiotherapy education and training) or control (information booklet alone) using sequentially numbered sealed opaque envelopes containing allocation cards wrapped in aluminium foil. For the purposes of this trial, conservative goals (minimum 10% absolute risk reduction from a 20% baseline PPC risk) were set considering time passed since previous audits and trials, known improvements in perioperative care during this time, and methodological limitations of previous research. (2012) are available to clinicians providing recommendations for post-UAS treatment. There was a gradient in PPC reduction according to surgical category, with the greatest response to preoperative physiotherapy in colorectal surgery, then upper gastrointestinal surgery, with the least difference between groups for urology (fig 4). Following this and on request (ianthe.boden@ths.tas.gov.au), the investigators will share the extended anonymised dataset (with associated coding library). A must read and practice by all medical personnel involved in pre, during, and post operation surgery. Observational studies associate PPC incidence with increased hospital length of stay.345678910 In our study, despite the incidence of PPCs being halved, a statistically significant reduction in length of stay was not detected in the overall population. The statistical analysis plan was prespecified20 and we used STATA (version 14.1) for all analyses. Data sharing: As prespecified a priori in the LIPPSMAck POP published protocol we welcome independent statistical analysis of our findings and provide open access to our anonymised primary dataset as an appendix. It may also be that we measured total combined acute and subacute length of stay. For our population the average length of stay was 11.4 (SD 11.0) days, with a range of 1 to 105 days. 2018 Jul;64(3):194. doi: 10.1016/j.jphys.2018.04.008. Ethical approval: This study was approved by the Human Research Ethics Committee (Tasmania) Network, Tasmania, Australia (H0011911) and the Health and Disability Ethics Committee, New Zealand (14/NTA/233) and informed written consent was given by all patients. We included most types of upper gastrointestinal, colorectal, and renal procedures involving traditional full length open incision approaches or via modern minimally invasive methods where smaller length incisions are preferred. Planned per protocol sensitivity analysis removing participants who had lower abdominal and laparoscopic surgery found strengthening of effect in the primary and most secondary outcomes in favour of physiotherapy (see appendix). The 12 month mortality effect size in our trial was an absolute risk reduction of 5% (12% v 7%). It is intended for patients who have had an abdominal surgery. There are many evidences that the number of PPC after abdominal surgery and open-heart surgery is reduced by preoperative PT programs. PPC=postoperative pulmonary complication, (a) 12 month mortality between groups; (b) 12 month mortality between groups in subgroup treated by experienced physiotherapists. To our knowledge we are one of few trials to assess the success of masking (see appendix). We considered that measuring such performance could have resulted in a Hawthorne effect by artificially reminding patients to adhere to the prescribed breathing exercises, and results would not be reflective of the pragmatic nature of the intervention. This site needs JavaScript to work properly. Allocation concealment in randomised controlled trials: are we getting better? Data are adjusted for age, respiratory comorbidity, and upper gastrointestinal surgery, Sensitivity analysis of subgroup effects on hospital length of stay. To ensure consistency in delivery, all physiotherapists viewed an audiovisual recording of the most experienced physiotherapist providing a preoperative intervention and were provided with a semi-scripted guide to the education session. Results were adjusted using backwards stepwise regression for specific baseline covariates considered a priori20 to affect primary outcome. We recommend that future research is directed towards, firstly, investigating the improved postoperative outcomes dependent on the experience level of physiotherapists providing the preoperative education; for example, is it the way an experienced physiotherapist delivers the intervention, or is it due to repetition and practice of delivering the intervention? Abdominal Surgery. Intention-to-treat unadjusted results showed statistically significantly fewer PPCs in the physiotherapy group (27/218, 12%) compared with control group (58/214, 27%); (absolute risk reduction 15%, 95% confidence interval 7% to 22%, P<0.001; table 3). These issues can slow down your recovery post-op, but if they are dealt with before surgery, you are likely to recover much quicker. Epub 2020 Jul 16. Written informed consent was gained before randomisation. Additionally, preoperative education to prevent PPCs has not been tested in the context of recent advances in perioperative management, such as minimally invasive surgery or enhanced recovery after surgery pathways,19 or where preoperative education is provided at outpatient clinics many weeks before surgery and by physiotherapists of different experience levels; both confounders of typical current practice at public and private hospitals. In the absence of high-quality research regarding post-operative physiotherapy management, consensus-based best practice Data were entered into locked electronic databases. Education focused on PPCs and their prevention through early ambulation and self directed breathing exercises to be initiated immediately on regaining consciousness after surgery. See: http://creativecommons.org/licenses/by-nc/4.0/. Within this booklet, breathing exercises were prescribed and consisted of two sets of 10 slow deep breaths followed by three coughs, to be performed hourly and starting immediately after surgery. Diagnosis confirmed when four or more criteria are present in a postoperative day: New abnormal breath sounds on auscultation different from in the preoperative assessment, Production of yellow or green sputum different from in the preoperative assessment, Pulse oximetry oxygen saturation (SpO2) <90% on room air on more than one consecutive postoperative day, Maximum oral temperature >38°C on more than one consecutive postoperative day, Chest radiography report of collapse or consolidation, An unexplained white cell count greater than 11×109/L, Presence of infection on sputum culture report, Physician’s diagnosis of pneumonia, lower or upper respiratory tract infection, an undefined chest infection, or prescription of an antibiotic for a respiratory infection. The management of pre-operative patients is a core function of junior doctors. USA.gov. Mathematical modelling finds that even with true randomisation, there is a 72.4% probability of two or more uneven covariates between groups if 50 covariates are included. The physiotherapy management of patients undergoing abdominal surgery @inproceedings{Reeve2016ThePM, title={The physiotherapy management of patients undergoing abdominal surgery}, author={J. Reeve and … PAC=preadmission clinic, Time to diagnosis of a postoperative pulmonary complication after surgery. A priori we estimated a sample of 398 patients would have 80% power to detect a significant difference between groups (P=0.05, two sided) with an 11% inflation to account for drop-outs, non-compliance, and uncertainty of baseline risk, providing a final sample size of 441. From the seventh postoperative day additional assessments were performed only as clinically suspected until day 14 when signs or symptoms of respiratory system deterioration were reported in the medical record. doi: 10.1136/bmj.l1862. The participants were educated that self directed breathing exercises were vital to protect their lungs during this inactivity phase and to commence them immediately on regaining consciousness and to continue them hourly until fully ambulant. Preoperative physiotherapy education prevented postoperative pulmonary complications following open upper abdominal surgery. Of these, 441 met the inclusion criteria and were randomly assigned to receive either an information booklet (n=219; control) or preoperative physiotherapy (n=222; intervention). JAMA Surg 2017;152:157-66. Secondly, preoperative education needs to be validated in other elective surgical populations such as cardiothoracic surgery and neurosurgery. Timing may be a key factor in reversing postoperative atelectasis.15 The time point of initiation of breathing exercises could be improved if patients were educated and trained before surgery to perform their breathing exercises immediately after surgery, rather than waiting for the first physiotherapy session, which is commonly not provided until the day after surgery.16. We do not capture any email address. Setting: We chose to use sealed envelopes as our trial was minimally funded and clinician initiated, and reliable internet access at all sites was not always ensured. IKR also receives information technology and library services from the University of Tasmania. This could just be a chance bias or a failure of true randomisation. 8824 to confirm the time of your surgery and when to arrive at the hospital. A single preoperative physiotherapy session reduced pulmonary complications after upper abdominal surgery. A PPC within the first 14 postoperative days was associated with increased mortality at all time points after surgery (unadjusted 12 month mortality: 24% (20/85) in participants with PPCs v 6% (20/347) without PPCs; P<0.001; adjusted data figure 1S: appendix). These prespecified covariates were respiratory comorbidity, smoking history, physical activity, age, obesity, duration of operation, surgical category, incision type, admission to intensive care, intraoperative ventilation, fluid delivery, blood transfusions, postoperative analgesia mode, and prophylactic antibiotics. A well written article. The independent impact of PPCs to affect length of stay may be less than previously reported when accounting for confounding factors. Prehabilitation in elective abdominal cancer surgery in older patients: systematic review and meta-analysis. In the absence of high-quality research regarding post-operative physiotherapy management, consensus-based best practice guidelines formulated by Hanekom et al. Trial registration: physiotherapy education includes-Pursed lip breathing exercises × 10 repetitions Diaphragmatic breathing exercises × 10 repetitions Leg ROM (active hip and knee flexion, extension and abduction exercises) and ankle toe movements exercises × 10 repititions Any published peer reviewed manuscripts derived from post hoc analysis of these shared data must list the LIPPSMAck POP investigators as coauthors. During this session, participants were educated about the possibility of PPCs after surgery and given an individualised risk assessment.7 The effect of anaesthesia and abdominal surgery on mucociliary clearance and lung volumes was explained. Physiotherapy Funding acknowledgements: Not applicable Relevance to physical therapy globally: Internationally, physiotherapists are widely involved in the management of patients undergoing major visceral surgery. Data are adjusted for age, respiratory comorbidity, and upper gastrointestinal surgery. This provided recommendations on hourly breathing and coughing exercises after surgery. Data are…, NLM Removal of these patients from analysis did not affect the reduction in PPCs (hazard ratio 0.48, 95% confidence interval 0.3 to 0.7). The Lung Infection Prevention Post Surgery Major Abdominal with Pre-Operative Physiotherapy (LIPPSMAck-POP) trial tested the hypothesis that preoperative education and breathing exercise training delivered within six weeks of surgery by physiotherapists reduces the incidence of PPCs after upper abdominal surgery. Online ahead of print. 2020 Jul 28;10(7):e037280. Results: After surgery, 15 (3%) breaches to the postoperative protocol occurred (see appendix). 10.1097/EJA.0000000000000646 Physiotherapy in upper abdominal surgery – what is the current practice in Australia? Possible explanations for this apparent paradox are that previously reported associative data between PPCs and length of stay is unadjusted for other factors that may influence both outcomes, such as surgical category, age, comorbidities, and other concurrent complications. technical support for your product directly (links go to external sites): Thank you for your interest in spreading the word about The BMJ.
