International consensus is needed on a core outcome set to advance the evidence of best practice in cancer prehabilitation services and research.

Prehabilitation aims to optimise patients' physical and psychological status before treatment. The types of outcomes measured to assess the impact of prehabilitation interventions vary across clinical research and service evaluation, limiting the ability to compare between studies and services and to pool data. An international workshop involving academic and clinical experts in cancer prehabilitation was convened in May 2022 at Sheffield Hallam University's Advanced Wellbeing Research Centre, England. The workshop substantiated calls for a core outcome set to advance knowledge and understanding of best practice in cancer prehabilitation and to develop national and international databases to assess outcomes at a population level.

Preoperative clear fluids fasting times in children: retrospective analysis of actual times and complications after the implementation of 1-h clear fasting.

BACKGROUND: Preoperative fasting before elective pediatric surgery is a matter of ongoing debate. The objectives of this study were to evaluate the compliance to a recently implemented preoperative fasting protocol (clear fluids until 1 hour from the induction of anesthesia), to identify predictors of prolonged preoperative fasting time, and to determine whether duration of preoperative fasting was associated with adverse outcomes. METHODS: Retrospective single-center study in an operating theater of a tertiary pediatric hospital. RESULTS: In a 6-month period, 1820 consecutive patients were analyzed. The data collected in the questionnaire reporting the time of last food, milk and/or liquid intake, and eventual reasons for nonadherence was analyzed. Median (interquartile range) preoperative fasting time was 186 (110-345) min. In 502 patients (27.6%), duration of preoperative fasting to clear fluid ranged from 60 to 119 min, whereas in 616 (34%) it was 120-240 min. The reasons for not respecting fasting time rules are mostly related to communication issues or unwillingness by the patients. A significant difference in fasting times was evident between infants and children older than 10 years (188, 105-290 vs. 198, 115-362; p = 0.02). Fasting times were significantly shorter in the inpatient group and in the first scheduled patients of the morning. Clear fluids fasting times were significantly longer in patients with hypovolemia complications than in those without, 373 (185-685) vs. 180 (110-330) min (p < 0.0001). Longer fasting times to clear fluids, younger age, and scheduled surgery time were independently associated with the odds of experiencing complications. CONCLUSIONS: In this single pediatric center study, median clear fluids fasting time was three times higher (180 min) than those recommended by the preoperative fasting protocol. Compliance to the protocol was observed in approximately 1 out of 4 patients (27.6%). Longer fasting times were associated with an increased risk of complications, which might be due to dehydration and/or hypovolemia.

Reporting quality of randomized controlled trials in prehabilitation: a scoping review.

BACKGROUND: Inadequate study reporting precludes interpretation of findings, pooling of results in meta-analyses, and delays knowledge translation. While prehabilitation interventions aim to enhance candidacy for surgery, to our knowledge, a review of the quality of reporting in prehabilitation has yet to be conducted. Our objective was to determine the extent to which randomized controlled trials (RCTs) of prehabilitation are reported according to methodological and intervention reporting checklists. METHODS: Eligibility criteria: RCTs of unimodal or multimodal prehabilitation interventions. SOURCES OF EVIDENCE: search was conducted in March 2022 using MEDLINE, Embase, PsychINFO, Web of Science, CINAHL, and Cochrane. CHARTING METHODS: identified studies were compared to CONSORT, CERT & Modified CERT, TIDieR, PRESENT, and CONSORT-SPI. An agreement ratio (AR) was defined to evaluate if applicable guideline items were correctly reported. Data were analyzed as frequency (n, %) and mean with standard deviation (SD). RESULTS: We identified 935 unique articles and included 70 trials published from 1994 to 2022. Most prehabilitation programs comprised exercise-only interventions (n = 40, 57%) and were applied before oncologic surgery (n = 32, 46%). The overall mean AR was 57% (SD: 20.9%). The specific mean ARs were as follows: CONSORT: 71% (SD: 16.3%); TIDieR: 62% (SD:17.7%); CERT: 54% (SD: 16.6%); Modified-CERT: 40% (SD:17.8%); PRESENT: 78% (SD: 8.9); and CONSORT-SPI: 47% (SD: 22.1). CONCLUSION: Altogether, existing prehabilitation trials report approximately half of the checklist items recommended by methodological and intervention reporting guidelines. Reporting practices may improve with the development of a reporting checklist specific to prehabilitation interventions.

Relationship between intensive care surge capacity and hospital factors: an extensive experience.

As a prolonged surge scenario, the COVID-19 pandemic has offered an unparalleled opportunity to improve hospital surge capacity (SC) understanding and the ability to manage it. In this study, the authors report the experience of a large hospital network and evaluate potential relationships between Intensive Care Units SC (ICU-SC) and some hospital-related variables: bed occupancy, emergency department admissions, ward admission from ED, and elective surgery procedures. Pearson's partial correlation coefficient (r) has been used to define the relationship between SC and the daily values of the above variables, collected through a dedicated digital platform that also ensured a regular quality check of the data. The observation has concerned several levels of analysis, namely two different types of SC calculation (SC base-SCb and SC actual-SCa), hospital category level and multi-hospital level, and two consecutive pandemic waves. Among the 16 hospitals observed, the correlation was shown to be moderate-positive with non-ICU bed occupancy (r/ = 0.62, r/ = 0.54), strong/moderate with ICU bed occupancy (r/ = 0.72, r/ = 0.54), and moderate with ward admissions from ED (r/ = 0.50, r/ = 0.51) On the contrary, the correlation proved to be moderate-negative with ED admissions (r/ = - 0.69, r/ = - 0.62) and low with the number of elective surgery procedures (r/ = - 0.10, r/ = - 0.16). This study identified a positive correlation between SC and three variables monitored: ICU bed occupancy, non-ICU bed occupancy, and ward admissions from ED. On the contrary, the correlation was negative for ED admission and the number of elective surgery procedures. The results have been confirmed across all levels of analysis adopted.

S110-Opioid-free analgesia after outpatient general surgery: A qualitative study focused on the perspectives of patients and clinicians involved in a pilot trial.

BACKGROUND: Opioid-free analgesia (OFA) may mitigate opioid-related harms after outpatient general surgery; however, the comparative effectiveness of this approach should be assessed in robust randomized controlled trials (RCTs). Undertaking an RCT on OFA raises important practical concerns, including surgeon and patient hesitation regarding pain management without opioids. We conducted a qualitative study to explore patients' and clinicians' perspectives and experiences with a pilot trial focused on OFA after outpatient general surgery. METHODS: Patients undergoing outpatient abdominal and breast procedures were randomized to receive post-discharge opioid analgesia (OA) or OFA. Semi-structured interviews with patients and clinicians involved in the trial were conducted to elicit personal perspectives and experiences. Purposive sampling for maximum variation was used to recruit participants with diverse characteristics. Transcribed interviews were assessed using inductive thematic analysis. RESULTS: Ten patients (5 abdominal, 5 breast) and 10 clinicians (6 surgeons, 2 anesthesiologists, 2 nurses) were interviewed. Five major themes emerged: readiness for trial engagement, pre-trial thoughts about the interventions, postoperative pain experiences, intervention acceptability, and trial refinement. Most patients were open to OFA. Clinicians expressed willingness to prescribe OFA, particularly after less invasive procedures and when using peripheral nerve blocks (PNBs). Concerns were raised regarding the adequacy of pain control and side effects of non-opioid drugs (e.g., NSAID-induced bleeding, kidney injury). Overall, participants were enthusiastic about the trial and recognized its relevance; clinicians praised the study design and organization; and patients valued the use of electronic questionnaires. Suggestions for improvements included preventing potential bias arising from the use of PNBs (i.e., via standardization or stratification) and reducing patient burden (i.e., decreasing postoperative questionnaires). CONCLUSION: Patients and clinicians who participated in a pilot RCT generally accept the clinical equipoise between OA versus OFA after outpatient general surgery and recognize the need for methodologically robust trials to inform evidence-based analgesia prescribing.

Future Perspectives on Prehabilitation Interventions in Cancer Surgery.

OBJECTIVE: This article provides a map of key knowledge gaps regarding the evidence supporting prehabilitation and its integration with enhanced recovery after surgery (ERAS) programs. Filling this lack of knowledge with future research will further establish the effectiveness of prehabilitation. DATA SOURCES: These are electronic databases including PubMed and CINAHL. CONCLUSION: Future efforts must embrace the elderly frail or cognitively impaired patient with specific needs to further promote restoration of postoperative function throughout the surgical pathway. Prehabilitation should be coupled and integrated within the existent concept of the ERAS framework, to facilitate the continuous evolution of screening, assessment, and optimization of high-risk surgical patients who are at risk of not being restored to physical and psychological function after surgery, including independence. IMPLICATIONS FOR NURSING PRACTICE: In the future, the ERAS nurse will be an essential figure of the prehabilitation program, proactively coordinating the assessment, optimization, and adjustment of perioperative comorbidity and guiding the rehabilitation process to improve patients' outcomes. These skills and characteristics will be required to provide optimal nursing care in the context of an integrated prehabilitation ERAS pathway.

Feasibility of Prospectively Comparing Opioid Analgesia With Opioid-Free Analgesia After Outpatient General Surgery: A Pilot Randomized Clinical Trial.

Importance: The overprescription of opioids to surgical patients is recognized as an important factor contributing to the opioid crisis. However, the value of prescribing opioid analgesia (OA) vs opioid-free analgesia (OFA) after postoperative discharge remains uncertain. Objective: To investigate the feasibility of conducting a full-scale randomized clinical trial (RCT) to assess the comparative effectiveness of OA vs OFA after outpatient general surgery. Design, Setting, and Participants: This parallel, 2-group, assessor-blind, pragmatic pilot RCT was conducted from January 29 to September 3, 2020 (last follow-up on October 2, 2020). at 2 university-affiliated hospitals in Montreal, Quebec, Canada. Participants were adult patients (aged ≥18 years) undergoing outpatient abdominal (ie, cholecystectomy, appendectomy, or hernia repair) or breast (ie, partial or total mastectomy) general surgical procedures. Exclusion criteria were contraindications to drugs used in the trial, preoperative opioid use, conditions that could affect assessment of outcomes, and intraoperative or early complications requiring hospitalization. Interventions: Patients were randomized 1:1 to receive OA (around-the-clock nonopioids and opioids for breakthrough pain) or OFA (around-the-clock nonopioids with increasing doses and/or addition of nonopioid medications for breakthrough pain) after postoperative discharge. Main Outcomes and Measures: Main outcomes were a priori RCT feasibility criteria (ie, rates of surgeon agreement, patient eligibility, patient consent, treatment adherence, loss to follow-up, and missing follow-up data). Secondary outcomes included pain intensity and interference, analgesic intake, 30-day unplanned health care use, and adverse events. Between-group comparison of outcomes followed the intention-to-treat principle. Results: A total of 15 surgeons were approached; all (100%; 95% CI, 78%-100%) agreed to have patients recruited and adhered to the study procedures. Rates of patient eligibility and consent were 73% (95% CI, 66%-78%) and 57% (95% CI, 49%-65%), respectively. Seventy-six patients were randomized (39 [51%] to OA and 37 [49%] to OFA) and included in the intention-to-treat analysis (mean [SD] age, 55.5 [14.5] years; 50 [66%] female); 40 (53%) underwent abdominal surgery, and 36 (47%) underwent breast surgery. Seventy-five patients (99%; 95% CI, 93%-100%) adhered to the allocated treatment; 1 patient randomly assigned to OFA received an opioid prescription. Seventeen patients (44%) randomly assigned to OA consumed opioids after discharge. Seventy-three patients (96%; 95% CI, 89%-99%) completed the 30-day follow-up. The rate of missing questionnaires was 37 of 3724 (1%; 95% CI, 0.7%-1.4%). All the a priori RCT feasibility criteria were fulfilled. Conclusions and Relevance: The findings of this pilot RCT support the feasibility of conducting a robust, full-scale RCT to inform evidence-based prescribing of analgesia after outpatient general surgery.

Opioid versus opioid-free analgesia after surgical discharge: a systematic review and meta-analysis of randomised trials.

BACKGROUND: Excessive opioid prescribing after surgery has contributed to the current opioid crisis; however, the value of prescribing opioids at surgical discharge remains uncertain. We aimed to estimate the extent to which opioid prescribing after discharge affects self-reported pain intensity and adverse events in comparison with an opioid-free analgesic regimen. METHODS: In this systematic review and meta-analysis, we searched MEDLINE, Embase, the Cochrane Library, Scopus, AMED, Biosis, and CINAHL from Jan 1, 1990, until July 8, 2021. We included multidose randomised controlled trials comparing opioid versus opioid-free analgesia in patients aged 15 years or older, discharged after undergoing a surgical procedure according to the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity definition (minor, moderate, major, and major complex). We screened articles, extracted data, and assessed risk of bias (Cochrane's risk-of-bias tool for randomised trials) in duplicate. The primary outcomes of interest were self-reported pain intensity on day 1 after discharge (standardised to 0-10 cm visual analogue scale) and vomiting up to 30 days. Pain intensity at further timepoints, pain interference, other adverse events, risk of dissatisfaction, and health-care reutilisation were also assessed. We did random-effects meta-analyses and appraised evidence certainty using the Grading of Recommendations, Assessment, Development, and Evaluations scoring system. The review was registered with PROSPERO (ID CRD42020153050). FINDINGS: 47 trials (n=6607 patients) were included. 30 (64%) trials involved elective minor procedures (63% dental procedures) and 17 (36%) trials involved procedures of moderate extent (47% orthopaedic and 29% general surgery procedures). Compared with opioid-free analgesia, opioid prescribing did not reduce pain on the first day after discharge (weighted mean difference 0·01cm, 95% CI -0·26 to 0·27; moderate certainty) or at other postoperative timepoints (moderate-to-very-low certainty). Opioid prescribing was associated with increased risk of vomiting (relative risk 4·50, 95% CI 1·93 to 10·51; high certainty) and other adverse events, including nausea, constipation, dizziness, and drowsiness (high-to-moderate certainty). Opioids did not affect other outcomes. INTERPRETATION: Findings from this meta-analysis support that opioid prescribing at surgical discharge does not reduce pain intensity but does increase adverse events. Evidence relied on trials focused on elective surgeries of minor and moderate extent, suggesting that clinicians can consider prescribing opioid-free analgesia in these surgical settings. Data were largely derived from low-quality trials, and none involved patients having major or major-complex procedures. Given these limitations, there is a great need to advance the quality and scope of research in this field. FUNDING: The Canadian Institutes of Health Research.

Neoadjuvant Prehabilitation Therapy for Locally Advanced Non-Small-Cell Lung Cancer: Optimizing Outcomes Throughout the Trajectory of Care.

BACKGROUND: Prehabilitation is well established for improving outcomes in cancer surgery. Combining prehabilitation with neoadjuvant treatments may provide an opportunity to rapidly initiate cancer-directed therapy while improving functional status in preparation for local consolidation. In this proof-of-concept study, we analyzed non-small-cell lung cancer patients who underwent simultaneous prehabilitation and neoadjuvant therapy. PATIENTS AND METHODS: We retrospectively analyzed all patients who underwent neoadjuvant treatment for non-small-cell lung cancer followed by curative intent surgery between 2015 and 2021. Patients who were screened for the prehabilitation program were identified. The screening included assessment of physical performance, nutritional status, and signs of anxiety and depression. RESULTS: We identified a total of 141 patients who underwent neoadjuvant therapy. Twenty patients were screened to undergo a prehabilitation program. Four patients did not complete the exercise program (1 surgical intervention too soon, 1 drop-out after the first session, and 2 patients were deemed fit without intervention). The postoperative median length of stay was 2 days (range 1-18). Patients improved their 6-minute-walk test despite undergoing neoadjuvant treatment by a mean of 33 meters (± 50, P = .1). Self-reported functional status (DASI) showed significant improvement by a mean of 10 points (± 11, P = .03), and HADS-anxiety-score was significantly reduced after the prehabilitation program by a mean of 1.5 points (± 1, P = .005). CONCLUSION: Neoadjuvant prehabilitation therapy is feasible and associated with encouraging results. The performance of all measures remains a logistic challenge. With multimodal strategies for lung cancer treatment becoming key to optimal outcomes, neoadjuvant prehabilitation therapy is a concept worthy of prospective multi-center evaluation.

North American multicentre evaluation of a same-day discharge protocol for minimally invasive colorectal surgery using mHealth or telephone remote post-discharge monitoring.

BACKGROUND: Same-day discharge (SDD) after colectomy is feasible but requires effective post-discharge remote follow-up. Previous studies have used in-person home visits or a mobile health (mHealth) phone app, but the use of simple telephone calls for remote follow-up has not yet been studied. Therefore, the objective of this study was to compare outcomes after SDD for minimally invasive colectomy using mHealth or telephone remote post-discharge follow-up. METHODS: A prospective cohort study was undertaken at two university-affiliated colorectal referral institutions from 02/2020 to 05/2021. Adult patients without significant comorbidities undergoing elective minimally invasive colectomy. Patients were discharged on the day of surgery based on set criteria. Post-discharge remote follow-up was performed using a mHealth app at site 1 and scheduled telephone calls at site 2 up to postoperative day (POD) 7. The main outcome for this study was the success rate of SDD, defined as discharge on POD0 without emergency department (ED) visit or readmission within the first 3 days. RESULTS: A total of 105 patients were recruited (site 1, n = 70; site 2, n = 35). Overall, 75% of patients were discharged on POD0 (site 1 81% vs. site 2 63%, p = 0.038), of which only two patients required an ED visit within the first 3 days, leading to an overall success rate of 73% (site 1 80% vs. site 2 60%, p = 0.029). The incidence of 30-day complications (16% vs. 20%, p = 0.583), ED visits (11% vs. 11%, p = 1.00), and readmissions (9% vs. 14%, p = 0.367) were similar between the two sites. There was only one patient at each study site that went to the ED without instructions through remote follow-up. CONCLUSIONS: A high proportion of patients planned for SDD were discharged on POD0 with few patients requiring an early unplanned ED visit. These results were similar with an mHealth app or telephone calls for post-discharge remote follow-ups, suggesting that SDD is feasible regardless of the method of post-discharge remote follow-up.

Tolerating clear fluids diet on postoperative day 0 predicts early recovery of gastrointestinal function after laparoscopic colectomy.

INTRODUCTION: A high proportion of colorectal surgery patients within an enhanced recovery pathway (ERP) do not experience complications but remain hospitalized mainly waiting for gastrointestinal (GI) recovery. Accurate identification of these patients may allow discharge prior to the return of GI function. Therefore, the objective of this study is to determine if tolerating clear fluid (CF) on postoperative day (POD) 0 was associated with uncomplicated return of GI function after laparoscopic colorectal surgery. METHODS: Pooled data from three prospective studies from a single specialist colorectal referral center were analyzed (2013-2019). The present study included adult patients that underwent elective laparoscopic colectomy without stoma. Postoperative GI symptoms were collected daily in all three datasets. The main exposure variable, whether CF diet was tolerated on POD0, was defined as patients drinking at least 300 mL of CF without any nausea, anti-emetics, or vomiting (CF+ vs CF-). The main outcome measure was time to GI-3 (tolerating solid diet and passage of gas or stools). RESULTS: A total of 221 patients were included in this study, including 69% CF+ and 31% CF-. The groups were similar in age, gender, and comorbidities, but the CF- patients were more likely to have surgery for inflammatory bowel disease. CF+ patients had faster time to GI-3 (mean 1.6d (SD 0.7) vs. 2.3d (SD 1.5), p < 0.001). The CF+ group also experienced fewer complications (19% vs. 35%, p = 0.009), shorter mean LOS (mean 3.6d (SD 2.9) vs. 6.2d (SD 9.4), p = 0.002), and were more likely to be discharged by the target LOS (66% vs. 50%, p = 0.024). CONCLUSION: Toleration of CF on POD0 was associated with faster return of GI function, fewer complications, and shorter LOS. This may be used as a criteria for potential discharge prior to full return of GI function after laparoscopic colectomy within an ERP.

Enhanced Recovery 2.0 - Same Day Discharge With Mobile App Follow-up After Minimally Invasive Colorectal Surgery.

OBJECTIVE: To investigate the feasibility of SDD protocol with postdischarge follow-up using a mobile phone app in patients undergoing elective minimally-invasive colectomy. SUMMARY OF BACKGROUND DATA: Discharge before gastrointestinal recovery and use of mobile health technology for remote follow-up may allow for SDD after minimally-invasive colectomy within an ERP. METHODS: Adult patients undergoing elective laparoscopic colectomy or loop ileostomy reversal from February 2020 to November 2020 were screened for eligibility. Patients were eligible if they lived within a 30-minute drive from the hospital, had an adequate support system at home, and owned a smart phone. Patients were discharged from the recovery room on the day of surgery based on set criteria with postdischarge remote follow-up using a mobile application. Feasibility was defined as discharge on the day of surgery without emergency department (ED) visit or readmission within the first 3 days. 30-day complications, ED visits, and readmissions were compared to a non-SDD historical cohort (May 2019-March 2020) also remotely followed-up using the same mobile phone app (standard ERP group). RESULTS: A total of 48 patients were recruited to SDD, of which 77% were discharged on the day of surgery without subsequent ED visit in the first 72 hours. There were 11 patients that could not be discharged, including 7 for failure of discharge criteria and 4 for intraoperative complications/concerns. Overall 30-day complications in the SDD group (17%) was similar to the standard ERP group (15%, P = 0.813). ED visits (SDD10% vs standard ERP8%, P = 0.664) and readmissions (6% vs 4%, P = 0.681) were also similar. CONCLUSIONS AND RELEVANCE: Findings from this study support the feasibility of a SDD protocol in select patients undergoing minimally-invasive colorectal resection. SDD colectomy protocols may represent the next evolution of ERP and postoperative recovery.

Trajectory of gastrointestinal function after laparoscopic colorectal surgery within an enhanced recovery pathway.

BACKGROUND: Early identification of colorectal surgery patients predicted to have uneventful gastrointestinal recovery may allow for early discharge. Our objective was to identify trajectories of gastrointestinal recovery within a colorectal surgery enhanced recovery pathway. METHODS: Data from 2 prospective studies enrolling adult patients undergoing elective laparoscopic colorectal resection at a specialist colorectal referral center were analyzed (2013-2019). All patients were managed according to a mature enhanced recovery pathway with a 3-day target length of stay. Postoperative gastrointestinal symptoms were collected daily and expressed using the validated I-FEED score. Latent-class growth curve (trajectory) analysis was used to identify different I-FEED trajectories over the first 3 postoperative days. RESULTS: A total of 192 patients were analyzed. Trajectory analysis identified 3 distinct trajectories: trajectory 1 had no gastrointestinal symptoms (41%); trajectory 2 had mild early symptoms with improvement over time (48%); and trajectory 3 had gastrointestinal symptoms that significantly worsened between postoperative days 1 and 2 (11%). I-FEED score ≤1 on postoperative day 1 predicted trajectory 1. Trajectory 1 had the best clinical outcomes, whereas trajectory 3 had the worst. CONCLUSION: I-FEED trajectory over postoperative days 1-3 was associated with clinical outcomes and may be used to predict gastrointestinal recovery. Findings from this study may inform clinical decision making regarding early hospital discharge within colorectal enhanced recovery pathways.

Revision Hip Arthroplasty in a Jehovah's Witness with Pelvic Discontinuity: A Case Report.

CASE: A 68-year-old Jehovah's Witness (JW) presented with pelvic discontinuity 9 years after right total hip arthroplasty. Her pelvis was previously irradiated for cervical cancer. Meticulous hemostasis, blood conserving strategies, and a prophylactic arterial balloon catheter were used to mitigate bleeding. She underwent an uneventful revision total hip arthroplasty with excellent functional recovery and radiographic evaluation at 1 year postoperatively. CONCLUSION: Pelvic discontinuity in a JW with irradiated bone makes for a challenging revision arthroplasty with high bleeding risk. Preoperative coordination with anesthesia and blood loss mitigation strategies can lead to successful surgical outcomes in cases of high-risk surgery among JW patients.

Functional capacity of prediabetic patients: effect of multimodal prehabilitation in patients undergoing colorectal cancer resection.

BACKGROUND: Prehabilitation is the process of increasing functional capacity (FC) before surgery. Poor glycemic control is associated with worse outcomes in patients undergoing surgery. Therefore, prediabetic patients could particularly benefit from prehabilitation. METHODS: This is a pooled analysis of individual patient data from three multimodal prehabilitation trials in colorectal cancer surgery. Following a baseline assessment using the 6-minute walking test (6MWT), subjects were randomized to multimodal prehabilitation or to a control group. Participants were reassessed 24 h before surgery and 4 weeks after surgery. Prediabetes (PreDM) was defined as HbA1c 5.7%-6.4%. Multivariable logistic regression was used to adjust for potentially confounding variables. RESULTS: Participation in a prehabilitation program was the most important predictive factor of clinical improvement in FC prior to surgery (Adjusted OR 2.42, 95% CI 1.18, 4.94); prediabetes was not a statistically significant predictor of improvement in FC after adjustments for covariates. Prehabilitation attenuated the loss of FC in unadjusted analyses after surgery in prediabetic patients (PreDM Control: median change -6 m [IQR -50-20] vs PreDM Prehab: median change +25 m [IQR -20-53], p = 0.045). Adjusted analyses also suggested the protective effect against loss of FC after surgery was stronger in prediabetic patients (PreDM Prehab vs PreDM Control: OR 5.5, 95% CI: 1.2-25.8; Normo Prehab vs Normo Control: OR 1.5, 95% CI: 0.53-4.52). CONCLUSIONS: Multimodal prehabilitation favored clinical recovery of FC after surgery in CRC patients, especially prediabetic patients.

Prehabilitation in Thoracic Cancer Surgery: From Research to Standard of Care.

OBJECTIVE: To determine whether personalized, stepped prehabilitation care is a feasible, safe, and effective implementation strategy. DESIGN: Quality improvement project. Data collected prospectively from August 2018 to December 2019 were analyzed retrospectively to describe the clinical implementation of a prehabilitation care program for elective lung cancer surgery. SETTING: Single center, tertiary university hospital. PARTICIPANTS: Eighty-one consecutive adult patients living in the metropolitan area of Montreal were included if an elective resection of suspected or confirmed lung cancer was planned. INTERVENTIONS: At the earliest contemplation of surgery, the whole cohort was screened for impaired physical, nutritional, and/or psychological status. Patients screened at higher risk received dedicated assessment and personalized prehabilitation care upon specific needs. MEASUREMENTS AND MAIN RESULTS: Patients' specific needs and their access and flow through the different services were described. Prehabilitation effectiveness was evaluated using walking and exercise tests, and adverse events were monitored. Eighty-one patients were screened for functional impairments. Forty patients showed reduction of physical function, seven of them refused the specific assessment, one refused in-hospital exercise; 48 patients showed nutritional risk, eight of them refused or did not comply with nutritional therapy. Overall, 45 high-risk patients received a one-month personalized prehabilitation program: 16 partook in a trimodal program (exercise, nutrition, and psychological), and 22 received a program with both nutrition and exercise. No adverse events occurred during the study period. After prehabilitation, six-minute waking distance improved by 29.9 meters (standard deviation 47.3 m) (n = 35; p = 0.001) and the oxygen uptake at the anaerobic threshold improved by 1.6 (1.7) mL/kg/min (n = 13; p = 0.004). Length of hospital stay was two (interquartile range one-four) days in prehabilitated patients versus three (two-seven) days in the usual care group (p = 0.101). CONCLUSIONS: A personalized, stepped prehabilitation program targeting high-risk patients undergoing elective lung cancer surgery was feasible, safe, and effective.

Implication of a novel postoperative recovery protocol to increase day 1 discharge rate after anatomic lung resection.

BACKGROUND: Chest-tube drainage and prolonged air leak after anatomic lung resection (ALR) continue to drive admission days for most programs employing minimal access techniques. The aim of the study was to evaluate the impact of a novel postoperative recovery protocol with revised chest tube management strategies to target discharge on post-operative day 1 (POD1) after ALR. METHODS: This is a pilot study investigating a novel enhanced recovery protocol which either allowed chest tube removal on POD1 or ambulatory management with indwelling chest tube using a portable closed drainage system. We included all patients undergoing video-assisted thoracoscopic surgery (VATS)-ALR; exclusion criteria were open surgery, non-anatomic or extended resections. RESULTS: A total of 139 patients were included in the study [N=29 portable drainage (PD), N=110 standard pathway (SP)]. POD1 discharge rate was 72% in PD vs. 15% in SP cohort (P<0.001). Median length of stay (LOS) was 1 day [interquartile range (IQR), 1-2 days] in PD cohort, while it was 3 days (IQR, 2-5 days) in SP cohort (P<0.001). There were no significant differences in length of indwelling chest-tube, rate of discharge with chest-tube, post-operative complications, or readmissions. On multivariate analysis, PD pathway as well as short surgical time were significant predictors of discharge on POD1. CONCLUSIONS: Our results indicate that POD1 discharge rates of 72% after VATS-ALR can be safely achieved by a well-developed perioperative care pathway and simple chest tube drainage interventions. Based on these findings we are currently drafting a follow-up study to investigate the possibility of performing ALRs as day surgery.

From preoperative assessment to preoperative optimization of frail older patiens.

Physiological and mental reserve decreases with age and the ability to mount a response to a stress like surgery can represent a burden to the frail and sarcopenic patient. It is necessary to evaluate the cardiorespiratory capacity and muscle strength before surgery in the older persons and prepare adequately to the same extent the marathon runner prepares before a full marathon. Assessment and stratification of risk are necessary for decision-making, but also for planning interventions aimed at improving the functional and emotional status in anticipation of surgery. Prehabilitation can improve the physiological reserve by optimizing cardiorespiratory capacity, muscle strength, and mental resiliency. Patients with low reserve and chronic medical conditions at high risk can benefit.
