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.

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.

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.

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.

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.

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.

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.

Validity of the I-FEED score for postoperative gastrointestinal function in patients undergoing colorectal surgery.

BACKGROUND: Postoperative ileus (POI) is common after gastrointestinal surgery and is associated with significant morbidity and costs. However, POI is poorly defined. The I-FEED score is a novel outcome measure for POI, developed by expert consensus. It contains five elements (intake, response to nausea treatment, emesis, exam, and duration, each scored with 0, 1, or 3 points) and classifies patients into normal, postoperative gastrointestinal intolerance (POGI), and postoperative gastrointestinal dysfunction (POGD). However, it has not yet been validated in a clinical context. The objective was to provide validity evidence for the I-FEED score to measure the construct of POI in patients undergoing colorectal surgery. METHODS: Data previously collected from a clinical trial investigating the impact of different perioperative fluid management strategies on primary POI in patients undergoing elective laparoscopic colectomy (2013-2015) were analyzed. Patients were managed by a longstanding Enhanced Recovery program (expected length of stay (LOS): 3 days). Daily I-FEED scores were generated (normal 0-2, POGI 3-5, POGD 6+ points) up to hospital discharge or postoperative day 7. Validity was assessed by testing the hypotheses that I-FEED score was higher (1) in patients with longer time to GI3 (tolerating diet + flatus/bowel movement), (2) with longer LOS (> 3 days vs shorter), (3) in patients with complications vs without, (4) in patients with poorer recovery (measured by Quality of Recovery-9 questionnaire). RESULTS: A total of 128 patients were included for analysis (mean age 61.7 years (SD 15.2), 57% male, 71% malignancy, and 39.1% rectal resection). Median LOS was 4 days [IQR3-5], and 32% experienced postoperative in-hospital morbidity. Overall, 48% of patients were categorized as normal, 22% POGI, and 30% POGD. The data supported all 4 hypotheses. CONCLUSIONS: This study contributes preliminary validity evidence for the I-FEED score as a measure for POI after colorectal surgery.

Development of a clinical pathway for enhanced recovery in colorectal surgery: a Canadian collaboration

Summary: Enhanced Recovery After Surgery (ERAS) is a model of care that was introduced in the late 1990s by a group of surgeons in Europe. The model consists of a number of evidence-based principles that support better outcomes for surgical patients, including improved patient experience, reduced length of stay in hospital, decreased complication rates and fewer hospital readmissions. A number of Canadian surgical care teams have already adopted ERAS principles and have reported positive outcomes. Arising from the Canadian Patient Safety Institute's Integrated Patient Safety Action Plan for Surgical Care Safety, and with support from numerous partner organizations from across the country, Enhanced Recovery Canada is leading the drive to improve surgical safety across the country and help disseminate these ERAS principles. We discuss the development of a multidisciplinary clinical pathway for elective colorectal surgery to help guide Canadian clinicians.

Preventing opioid prescription after major surgery: a scoping review of opioid-free analgesia.

BACKGROUND: Excessive opioid prescribing after surgery has been recognised as a contributor to the current crisis of opioid addiction and overdose. Clinicians may potentially tackle this crisis by using opioid-free postoperative analgesia; however, the scientific literature addressing this approach is sparse and heterogeneous, thereby limiting robust conclusions. A scoping review was conducted to systematically map the extent, range, and nature of the literature addressing postoperative opioid-free analgesia. METHODS: Eight bibliographic databases were searched for studies addressing opioid-free analgesia after a major surgery. We extracted the study characteristics, including design, country, year, surgical procedure(s), and interventions. Results were organised thematically according to surgical specialty and targeted phase of recovery: in hospital (early recovery, ≤24 h after operation; intermediate recovery, >24 h) and post-discharge (late recovery). Reporting was according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement for scoping reviews. RESULTS: We identified 424 studies addressing postoperative opioid-free analgesia. The number of studies conducted in countries where the opioid crisis is primarily focused was remarkably low (USA, n=11 [3%]; Canada, n=5 [1%]). Many RCTs compared opioid-free vs opioid analgesia during hospital stay (n=117), but few targeted analgesia post-discharge (n=8). Studies were predominantly focused on procedures in orthopaedic, general, and gynaecological/obstetric surgery. Limited attention has been directed towards non-pharmacological pain interventions. We did not identify knowledge synthesis studies (i.e. systematic reviews and meta-analyses) focused on the comparative effectiveness of opioid-free vs opioid analgesia. CONCLUSIONS: Opioids remain a mainstay analgesic for managing pain after surgery, but alternative analgesia strategies should not be overlooked. This scoping review indicates numerous opportunities for future research targeting opioid-free postoperative analgesia. REVIEW REGISTRATION: http://www.researchregistry.com; ID: reviewregistry576.

Incidence and predictors of prolonged postoperative ileus after colorectal surgery in the context of an enhanced recovery pathway.

BACKGROUND: Prolonged postoperative ileus (PPOI) is common after colorectal surgery but has not been widely studied in the context of enhanced recovery pathways (ERPs) that include interventions aimed to accelerate gastrointestinal recovery. The aim of this study is to estimate the incidence and predictors of PPOI in the context of an ERP for colorectal surgery. METHODS: We analyzed data from an institutional colorectal surgery ERP registry. Incidence of PPOI was estimated according to a definition adapted from Vather (intolerance of solid food and absence of flatus or bowel movement for ≥ 4 days) and compared to other definitions in the literature. Potential risk factors for PPOI were identified from previous studies, and their predictive ability was evaluated using Bayesian model averaging (BMA). Results are presented as posterior effect probability (PEP). Evidence of association was categorized as: no evidence (PEP < 50%), weak evidence (50-75%), positive evidence (75-95%), strong evidence (95-99%), and very strong evidence (> 99%). RESULTS: There were 323 patients analyzed (mean age 63.5 years, 51% males, 74% laparoscopic, 33% rectal resection). The incidence of PPOI was 19% according to the primary definition, but varied between 11 and 59% when using other definitions. On BMA analysis, intraoperative blood loss (PEP 99%; very strong evidence), administration of any intravenous opioids in the first 48 h (PEP 94%; strong evidence), postoperative epidural analgesia (PEP 56%; weak evidence), and non-compliance with intra-operative fluid management protocols (3 ml/kg/h for laparoscopic and 5 ml/kg/h for open; PEP 55%, weak evidence) were predictors of PPOI. CONCLUSIONS: The incidence of PPOI after colorectal surgery is high even within an established ERP and varied considerably by diagnostic criteria, highlighting the need for a consensus definition. The use of intravenous opioids is a modifiable strong predictor of PPOI within an ERP, while the role of epidural analgesia and intraoperative fluid management should be further evaluated.

Goal-directed Fluid Therapy Does Not Reduce Primary Postoperative Ileus after Elective Laparoscopic Colorectal Surgery: A Randomized Controlled Trial.

BACKGROUND: Inadequate perioperative fluid therapy impairs gastrointestinal function. Studies primarily evaluating the impact of goal-directed fluid therapy on primary postoperative ileus are missing. The objective of this study was to determine whether goal-directed fluid therapy reduces the incidence of primary postoperative ileus after laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. METHODS: Randomized patient and assessor-blind controlled trial conducted in adult patients undergoing laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Patients were assigned randomly to receive intraoperative goal-directed fluid therapy (goal-directed fluid therapy group) or fluid therapy based on traditional principles (control group). Primary postoperative ileus was the primary outcome. RESULTS: One hundred twenty-eight patients were included and analyzed (goal-directed fluid therapy group: n = 64; control group: n = 64). The incidence of primary postoperative ileus was 22% in the goal-directed fluid therapy and 22% in the control group (relative risk, 1; 95% CI, 0.5 to 1.9; P = 1.00). Intraoperatively, patients in the goal-directed fluid therapy group received less intravenous fluids (mainly less crystalloids) but a greater volume of colloids. The increase of stroke volume and cardiac output was more pronounced and sustained in the goal-directed fluid therapy group. Length of hospital stay, 30-day postoperative morbidity, and mortality were not different. CONCLUSIONS: Intraoperative goal-directed fluid therapy compared with fluid therapy based on traditional principles does not reduce primary postoperative ileus in patients undergoing laparoscopic colorectal surgery in the context of an Enhanced Recovery After Surgery program. Its previously demonstrated benefits might have been offset by advancements in perioperative care.

Impact of adherence to care pathway interventions on recovery following bowel resection within an established enhanced recovery program.

INTRODUCTION: Guidelines recommend incorporation of more than 20 perioperative interventions within an enhanced recovery program (ERP). However, the impact of overall adherence to the pathway and the relative contribution of each intervention are unclear. The aim of this study was to estimate the extent to which adherence to ERP elements is associated with outcomes and identify key ERP elements predicting successful recovery following bowel resection. METHODS: Prospectively collected data entered in a registry specifically designed for ERPs were reviewed. Patients undergoing elective bowel resection between 2012 and 2014 were treated within an ERP comprising 23 care elements. Primary outcome was successful recovery defined as the absence of complications, discharge by postoperative day 4 and no readmission. Secondary outcomes were length of hospital stay (LOS), 30-day morbidity, and severity (Comprehensive complication index, CCI, 0-100). Regression analyses were adjusted for potential confounders. RESULTS: A total of 347 patients were included in the study. Median primary LOS was 4 days (IQR 3-7). Patients were adherent to median 18 (IQR 16-20) elements. A total of 156 (45 %) patients had successful recovery. Morbidity occurred in 175 (50 %) patients with median CCI 8.6 (IQR 0-22.6). There was a positive association between adherence and successful recovery (OR 1.39 for every additional element, p < 0.001), LOS (11 % reduction for every additional element, p < 0.001), 30-day postoperative morbidity (OR 0.78, p < 0.001), and the CCI (17 % reduction, p < 0.001). Laparoscopy (OR 4.32, p < 0.001), early mobilization out of bed (OR 2.25, p = 0.021), and early termination of IV fluid infusion (OR 2.00, p = 0.013) significantly predicted successful recovery. These factors were also associated with reduced morbidity and complication severity. CONCLUSIONS: Increased adherence to ERP interventions was associated with successful early recovery and a reduction in postoperative morbidity and complication severity. In an established ERP where overall adherence was high, laparoscopic approach, perioperative fluid management, and patient mobilization remain key elements associated with improved outcomes.

Multimodal Prehabilitation for Patients with Crohn's Disease Scheduled for Major Surgery: A Narrative Review.

Approximately 15-50% of patients with Crohn's disease (CD) will require surgery within ten years following the diagnosis. The management of modifiable risk factors before surgery is essential to reduce postoperative complications and to promote a better postoperative recovery. Preoperative malnutrition reduced functional capacity, sarcopenia, immunosuppressive medications, anemia, and psychological distress are frequently present in CD patients. Multimodal prehabilitation consists of nutritional, functional, medical, and psychological interventions implemented before surgery, aiming at optimizing preoperative status and improve postoperative recovery. Currently, studies evaluating the effect of multimodal prehabilitation on postoperative outcomes specifically in CD are lacking. Some studies have investigated the effect of a single prehabilitation intervention, of which nutritional optimization is the most investigated. The aim of this narrative review is to present the physiologic rationale supporting multimodal surgical prehabilitation in CD patients waiting for surgery, and to describe its main components to facilitate their adoption in the preoperative standard of care.

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.

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.

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.
