RESUMO
BACKGROUND: Dexmedetomidine is increasingly used for surgical patients requiring general anaesthesia. However, its effectiveness on patient-centred outcomes remains uncertain. Our main objective was to evaluate the patient-centred effectiveness of intraoperative dexmedetomidine for adult patients requiring surgery under general anaesthesia. METHODS: We conducted a systematic search of MEDLINE, Embase, CENTRAL, Web of Science, and CINAHL from inception to October 2023. Randomised controlled trials (RCTs) comparing intraoperative use of dexmedetomidine with placebo, opioid, or usual care in adult patients requiring surgery under general anaesthesia were included. Study selection, data extraction, and risk of bias assessment were performed by two reviewers independently. We synthesised data using a random-effects Bayesian regression framework to derive effect estimates and the probability of a clinically important effect. For continuous outcomes, we pooled instruments with similar constructs using standardised mean differences (SMDs) and converted SMDs and credible intervals (CrIs) to their original scale when appropriate. We assessed the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Our primary outcome was quality of recovery after surgery. To guide interpretation on the original scale, the Quality of Recovery-15 (QoR-15) instrument was used (range 0-150 points, minimally important difference [MID] of 6 points). RESULTS: We identified 49,069 citations, from which 44 RCTs involving 5904 participants were eligible. Intraoperative dexmedetomidine administration was associated with improvement in postoperative QoR-15 (mean difference 9, 95% CrI 4-14, n=21 RCTs, moderate certainty of evidence). We found 99% probability of any benefit and 88% probability of achieving the MID. There was a reduction in chronic pain incidence (odds ratio [OR] 0.42, 95% CrI 0.19-0.79, n=7 RCTs, low certainty of evidence). There was also increased risk of clinically significant hypotension (OR 1.98, 95% CrI 0.84-3.92, posterior probability of harm 94%, n=8 RCTs) and clinically significant bradycardia (OR 1.74, 95% CrI 0.93-3.34, posterior probability of harm 95%, n=10 RCTs), with very low certainty of evidence for both. There was limited evidence to inform other secondary patient-centred outcomes. CONCLUSIONS: Compared with placebo or standard of care, intraoperative dexmedetomidine likely results in meaningful improvement in the quality of recovery and chronic pain after surgery. However, it might increase clinically important bradycardia and hypotension. SYSTEMATIC REVIEW PROTOCOL: PROSPERO (CRD42023439896).

Background: There are high rates of computed tomography (CT) utilization in the emergency department (ED) for patients with inflammatory bowel disease (IBD), despite guidelines recommending judicious use. We performed a national survey to better understand perceptions and practice patterns of Canadian physicians related to CT imaging in the ED. Methods: Our survey was developed by a multistep iterative process with input from key stakeholders between 2021 and 2022. It evaluated Canadian gastroenterologists', surgeons', and emergency physicians' (1) perceived rates of IBD findings detected by CT, (2) likelihood of performing CT for specific presentations and (3) comfort in diagnosing IBD phenotypes/complications without CT. Results: A total of 208 physicians responded to our survey: median age 44 years (IQR, 37-50), 63% male, 68% academic, 44% emergency physicians, 39% gastroenterologists, and 17% surgeons. Compared with emergency physicians and surgeons, gastroenterologists more often perceived that CT would detect inflammation alone and less often IBD complications. Based on established rates in the literature, 13 (16%) gastroenterologists, 33 (40%) emergency physicians, and 21 (60%) surgeons overestimated the rates of at least one IBD complication. Although most physicians were more comfortable diagnosing inflammation compared to IBD complications without CT, gastroenterologists were significantly less likely to recommend CT imaging for non-obstructive/penetrating presentations compared with emergency physicians and surgeons with results that varied by IBD subtype. Conclusion: This national survey demonstrates differences in physician perceptions and practices regarding CT utilization in the ED and can be used as a framework for educational initiatives regarding appropriate usage of this modality.
RESUMO
BACKGROUND: Preoperative anaemia is common in patient undergoing colorectal surgery. Understanding the population-level costs of preoperative anaemia will inform development and evaluation of anaemia management at health system levels. METHODS: This was a population-based cohort study using linked, routinely collected data, including residents from Ontario, Canada, aged ≥18 yr who underwent an elective colorectal resection between 2012 and 2022. Primary exposure was preoperative anaemia (haemoglobin <130 g L-1 in males; <120 g L-1 in females). Primary outcome was 30-day costs in 2022 Canadian dollars (CAD), from the perspective of a publicly funded healthcare system. Secondary outcomes included red blood cell transfusion, major adverse events (MAEs), length of stay (LOS), days alive at home (DAH), and readmissions. RESULTS: We included 54,286 patients, with mean 65.3 (range 18-102) years of age and 49.0% females, among which 21 264 (39.2%) had preoperative anaemia. There was an absolute adjusted cost increase of $2671 per person at 30 days after surgery attributable to preoperative anaemia (ratio of means [RoM] 1.05, 95% confidence interval [CI] 1.04-1.06). Compared with the control group, 30-day risks of transfusion (odds ratio [OR] 4.34, 95% CI 4.04-4.66), MAEs (OR 1.14, 95% CI 1.03-1.27), LOS (RoM 1.08, 95% CI 1.07-1.10), and readmissions (OR 1.16, 95% CI 1.08-1.24) were higher in the anaemia group, with reduced DAH (RoM 0.95, 95% CI 0.95-0.96). CONCLUSIONS: Approximately $2671 CAD per person in 30-day health system costs are attributable to preoperative anaemia after colorectal surgery in Ontario, Canada.

INTRODUCTION: Dexmedetomidine is a promising pharmaceutical strategy to minimise opioid use during surgery. Despite its growing use, it is uncertain whether dexmedetomidine can improve patient-centred outcomes such as quality of recovery and pain. METHODS AND ANALYSIS: We will conduct a systematic review and meta-analysis following the recommendations of the Cochrane Handbook for Systematic Reviews. We will search MEDLINE, Embase, CENTRAL, Web of Science and CINAHL approximately in October 2023. We will include randomised controlled trials evaluating the impact of systemic intraoperative dexmedetomidine on patient-centred outcomes. Patient-centred outcome definition will be based on the consensus definition established by the Standardised Endpoints in Perioperative Medicine initiative (StEP-COMPAC). Our primary outcome will be the quality of recovery after surgery. Our secondary outcomes will be patient well-being, function, health-related quality of life, life impact, multidimensional assessment of postoperative acute pain, chronic pain, persistent postoperative opioid use, opioid-related adverse events, hospital length of stay and adverse events. Two reviewers will independently screen and identify trials and extract data. We will evaluate the risk of bias of trials using the Cochrane Risk of Bias Tool (RoB 2.0). We will synthesise data using a random effects Bayesian model framework, estimating the probability of achieving a benefit and its clinical significance. We will assess statistical heterogeneity with the tau-squared and explore sources of heterogeneity with meta-regression. We have involved patient partners, clinicians, methodologists, and key partner organisations in the development of this protocol, and we plan to continue this collaboration throughout all phases of this systematic review. ETHICS AND DISSEMINATION: Our systematic review does not require research ethics approval. It will help inform current clinical practice guidelines and guide development of future randomised controlled trials. The results will be disseminated in open-access peer-reviewed journals, presented at conferences and shared among collaborators and networks. PROSPERO REGISTRATION NUMBER: CRD42023439896.

BACKGROUND: Postoperative patient-centred outcome measures are essential to capture the patient's experience after surgery. Although a large number of pharmacologic opioid minimisation strategies (i.e. opioid alternatives) are used for patients undergoing surgery, it remains unclear which strategies are most promising in terms of patient-centred outcome improvements. This scoping review had two main objectives: (1) to map and describe evidence from clinical trials assessing the patient-centred effectiveness of pharmacologic intraoperative opioid minimisation strategies in adult surgical patients, and (2) to identify promising pharmacologic opioid minimisation strategies. METHODS: We searched MEDLINE, Embase, CENTRAL, Web of Science, and CINAHL databases from inception to February 2023. We included trials investigating the use of opioid minimisation strategies in adult surgical patients and reporting at least one patient-centred outcome. Study screening and data extraction were conducted independently by at least two reviewers. RESULTS: Of 24,842 citations screened for eligibility, 2803 trials assessed the effectiveness of intraoperative opioid minimisation strategies. Of these, 457 trials (67,060 participants) met eligibility criteria, reporting at least one patient-centred outcome. In the 107 trials that included a patient-centred primary outcome, patient wellbeing was the most frequently used domain (55 trials). Based on aggregate findings, dexmedetomidine, systemic lidocaine, and COX-2 inhibitors were promising strategies, while paracetamol, ketamine, and gabapentinoids were less promising. Almost half of the trials (253 trials) did not report a protocol or registration number. CONCLUSIONS: Researchers should prioritise and include patient-centred outcomes in the assessment of opioid minimisation strategy effectiveness. We identified three potentially promising pharmacologic intraoperative opioid minimisation strategies that should be further assessed through systematic reviews and multicentre trials. Findings from our scoping review may be influenced by selective outcome reporting bias. STUDY REGISTRATION: OSF - https://osf.io/7kea3.

INTRODUCTION: Identifying the optimal treatment for anal fistula has been challenging. Since first reported in 2007, the ligation of the intersphincteric fistula tract (LIFT) procedure has reported healing rates between 40% and 95% and is being increasingly adopted. The BioLIFT is an augmentation of the LIFT with an intersphincteric bioprosthetic mesh and has reported healing rates between 69% and 94%. Despite increased costs and potential complications associated with mesh, the evidence comparing healing rates between BioLIFT and LIFT is unknown. This study details the protocol for a systematic review and meta-analysis of BioLIFT and LIFT to compare outcomes associated with each procedure. METHODS AND ANALYSIS: MEDLINE, EMBASE and the Cochrane Database will be searched from inception using a search strategy designed by an information specialist. Randomised controlled trials, prospective and retrospective cohort studies, consecutive series, cross-sectional studies and case series with more than five patients will be included. Both comparative and single group studies will be included. The eligible population will be adult patients undergoing BioLIFT or LIFT for trans-sphincteric anal fistula. The primary outcome will be primary healing rate. Secondary outcomes will capture secondary healing rate and complications. Abstract, full text and data extraction will be completed independently and in duplicate by two reviewers. Study risk of bias will be assessed using Risk of Bias In Non-randomized Studies - of Interventions and the Risk of Bias (RoB 2.0) tool. Quality of evidence for outcomes will be evaluated using Grading of Recommendations, Assessment, Development and Evaluations criteria. A meta-analysis will be performed using a random-effects inverse variance model. Subgroup and sensitivity analyses will be explored in relation to complex fistula characteristics and patients who have undergone previous LIFT. Heterogeneity will be assessed using the I2 statistic. ETHICS AND DISSEMINATION: This review does not require research ethics board approval. This study will be completed in September 2022. The findings of this study will be disseminated through peer-reviewed international conferences and journals. PROSPERO REGISTRATION NUMBER: CRD42020127996.

Shared Care Models (SCMs), in which a team of clinicians share in patient care and resource utilization, represent an opportunity for surgeon-level system change. We aimed to identify the queues and stakeholders within a complex gastrointestinal surgical care pathway to demonstrate the implications of a SCM on system efficiency. A multidisciplinary group of surgeons and care navigators working in SCMs were asked to develop a patient encounter map through consensus to illustrate relevant queues and stakeholders within a SCM. Fifteen surgeon-related queues were identified, each representing a point of potential delay to care in the patient's journey that could be addressed by shared care. A final patient encounter map was created, and advantages and challenges of SCMs were also described from multidisciplinary group discussions. The numerous queues identified in this map ultimately reflected opportunities for more efficient care navigation under a SCM through increased surgeon availability and shared resource utilization.

BACKGROUND: Accurate tools to distinguish Crohn's disease [CD] from cryptoglandular disease in patients with perianal fistulas without detectable luminal inflammation on ileocolonoscopy and abdominal enterography (isolated perianal fistulas [IPF]) are lacking. We assessed the ability of video capsule endoscopy [VCE] to detect luminal inflammation in patients with IPF. METHODS: We studied consecutive adults [>17 years] with IPF who were evaluated by VCE after a negative ileocolonoscopy and abdominal enterography between 2013 and 2022. We defined luminal CD by VCE as diffuse erythema, three or more aphthous ulcers, or a Lewis score greater than 135. We compared rates of intestinal inflammation in this cohort with age- and sex-matched controls without perianal fistulas, who underwent VCE for other indications. We excluded persons with pre-existing inflammatory bowel disease [IBD] and exposure to non-steroidal anti-inflammatory drugs or immunosuppressive treatments. RESULTS: A total of 45 patients with IPF underwent VCE without complications. Twelve patients [26%] met our definition of luminal CD. Luminal CD was more common in patients with IPF than in controls [26% vs 3%; pâ <0.01]. Among patients with IPF, male sex (OR [odds ratio], 9.2; 95% confidence interval [CI] [1.1-79.4]), smoking (OR, 4.5; 95% CI [0.9-21.2]), abscess (OR, 6.3; 95% CI [1.5-26.8]), rectal enhancement on magnetic resonance imaging [MRI] (OR, 9.0; 95% CI [0.8-99.3]), and positive antimicrobial serology (OR, 7.1; 95% CI, [0.7-70.0]) were more common in those with a positive VCE study. CONCLUSIONS: VCE detected small intestinal inflammation suggestive of luminal CD in approximately one-quarter of patients with IPF. Larger studies are required to validate these findings.

INTRODUCTION: For close to a century opioid administration has been a standard of care to complement anaesthesia during surgery. Considering the worldwide opioid epidemic, this practice is now being challenged and there is a growing use of systemic pharmacological opioid minimising strategies. Our aim is to conduct a scoping review that will examine clinical trials that have evaluated the impact of intraoperative opioid minimisation strategies on patient-centred outcomes and identify promising strategies. METHODS AND ANALYSIS: Our scoping review will follow the framework developed by Arksey and O'Malley. We will search MEDLINE, Embase, CENTRAL, Web of Science and CINAHL from their inception approximately in March 2023. We will include randomised controlled trials, assessing the impact of systemic intraoperative pharmacologic opioid minimisation strategies on patient-centred outcomes. We define an opioid minimisation strategy as any non-opioid drug with antinociceptive properties administered during the intraoperative period. Patient-centred outcomes will be defined and classified based on the consensus definitions established by the Standardised Endpoints in Perioperative Medicine initiative (StEP-COMPAC group) and informed by knowledge users and patient partners. We will use a coproduction approach involving interested parties. Our multidisciplinary team includes knowledge users, patient partners, methodologists and knowledge user organisations. Knowledge users will provide input on methods, outcomes, clinical significance of findings, implementation and feasibility. Patient partners will participate in assessing the relevance of our design, methods and outcomes and help to facilitate evidence translation. We will provide a thorough description of available clinical trials, compare their reported patient-centred outcome measures with established recommendations and identify promising strategies. ETHICS AND DISSEMINATION: Ethics approval is not required for the review. Our scoping review will inform future research including clinical trials and systematic reviews through identification of important intraoperative interventions. Results will be disseminated through a peer-reviewed publication, presentation at conferences and through our network of knowledge user collaborators.

OBJECTIVE: To compare predictive accuracy of frailty instruments operationalizable in electronic data for prognosticating outcomes among older adults undergoing emergency general surgery (EGS). BACKGROUND: Older patients undergoing EGS are at higher risk of perioperative morbidity and mortality. Preoperative frailty is a common and strong perioperative risk factor in this population. Despite this, existing barriers preclude routine preoperative frailty assessment. METHODS: We conducted a retrospective cohort study of adults above 65 undergoing EGS from 2012 to 2018 using Institute for Clinical Evaluative Sciences (ICES) provincial healthcare data in Ontario, Canada. We compared 4 frailty instruments: Frailty Index (FI), Hospital Frailty Risk Score (HFRS), Risk Analysis Index-Administrative (RAI), ACG Frailty-defining diagnoses indicator (ACG). We compared predictive accuracy beyond baseline risk models (age, sex, American Society of Anesthesiologists' score, procedural risk). Predictive performance was measured using discrimination, calibration, explained variance, net reclassification index and Brier score (binary outcomes); using explained variance, root mean squared error and mean absolute prediction error (continuous outcomes). Primary outcome was 30-day mortality. Secondary outcomes were 365-day mortality, nonhome discharge, days alive at home, length of stay, and 30-day and 365-day health systems cost. RESULTS: A total of 121,095 EGS patients met inclusion criteria. Of these, 11,422 (9.4%) experienced death 30 days postoperatively. Addition of FI, HFRS, and RAI to the baseline model led to improved discrimination, net reclassification index, and R2 ; RAI demonstrated the largest improvements. CONCLUSIONS: Adding 4 frailty instruments to typically assessed preoperative risk factors demonstrated strong predictive performance in accurately prognosticating perioperative outcomes. These findings can be considered in developing automated risk stratification systems among older EGS patients.

Variation in data provides an opportunity for health care providers to assess how patient care can be improved. Pan-Canadian colorectal cancer data show that, although long-term survival is similar among provinces, differences exist in other important aspects of care: length of stay, minimally invasive approach, readmission, and short-term mortality. Examining variation among stakeholders involved with colorectal cancer allows the opportunity to reflect on and optimize care.

BACKGROUND: The Consultation and Relational Empathy (CARE) Measure, a validated questionnaire designed to assess patients' perceptions of their physician's communication skills and empathy, has been used to assess empathy in medical specialties but has seldom been applied to surgery. We assessed empathy and communication skills among a group of surgeons within a single academic institution. METHODS: All surgeons within our department of surgery were invited to participate. Patients seen in clinics of participating surgeons were recruited prospectively from July 2018 to February 2019. At the end of each clinical encounter, they were asked to complete a CARE survey. Surveys were analyzed according to previously validated inclusion and exclusion criteria. We calculated mean scores for each surgeon and surgical division. About 6 months after study completion, surgeons were provided with their individual score and de-identified division scores, and were asked to complete a follow-up survey assessing their attitudes toward the CARE Measure. RESULTS: Of the 82 surgeons invited, 51 (62%) agreed to participate; 7 had fewer than 25 completed surveys and were excluded from analysis. A total of 1801 surveys for 44 surgeons (33 male and 11 female) were included in the final analysis. The average CARE score across the department was 46.9 (95% confidence interval [CI] 46.6-47.1). Female surgeons received significantly higher scores than male surgeons (mean 47.6 [95% CI 47.1-48.0] v. 46.7 [95% CI 46.4-48.0]). Of the 35 surgeons who responded to the follow-up survey, 31 (89%) felt that the questions in the CARE Measure applied to their practice, and half of these reported that they intended to make changes in response to the feedback. CONCLUSION: We found high communication and empathy scores among surgeons in the outpatient setting, with enough variability to encourage continued improvement. The CARE Measure appears to have face validity among surgeons, and the vast majority found it relevant to their practice. Further study is needed to formally assess the relevance, performance, reliability and construct validity of this measure.

OBJECTIVE: To determine the efficacy and safety of extended duration perioperative thromboprophylaxis by low molecular weight heparin when assessing disease-free survival in patients undergoing resection for colorectal cancer. DESIGN: Multicentre, open label, randomised controlled trial. SETTINGS: 12 hospitals in Quebec and Ontario, Canada, between 25 October 2011 and 31 December 2020. PARTICIPANTS: 614 adults (age ≥18 years) were eligible with pathologically confirmed invasive adenocarcinoma of the colon or rectum, no evidence of metastatic disease, a haemoglobin concentration of ≥8 g/dL, and were scheduled to undergo surgical resection. INTERVENTIONS: Random assignment to extended duration thromboprophylaxis using daily subcutaneous tinzaparin at 4500 IU, beginning at decision to operate and continuing for 56 days postoperatively, compared with in-patient postoperative thromboprophylaxis only. MAIN OUTCOME MEASURES: Primary outcome was disease-free survival at three years, defined as survival without locoregional recurrence, distant metastases, second primary (same cancer), second primary (other cancer), or death. Secondary outcomes included venous thromboembolism, postoperative major bleeding complications, and five year overall survival. Analyses were done in the intention-to-treat population. RESULTS: The trial stopped recruitment prematurely after the interim analysis for futility. The primary outcome occurred in 235 (77%) of 307 patients in the extended duration group and in 243 (79%) of 307 patients in the in-hospital thromboprophylaxis group (hazard ratio 1.1, 95% confidence interval 0.90 to 1.33; P=0.4). Postoperative venous thromboembolism occurred in five patients (2%) in the extended duration group and in four patients (1%) in the in-hospital thromboprophylaxis group (P=0.8). Major surgery related bleeding in the first postoperative week was reported in one person (<1%) in the extended duration and in six people (2%) in the in-hospital thromboprophylaxis group (P=0.1). No difference was noted for overall survival at five years in 272 (89%) patients in the extended duration group and 280 (91%) patients in the in-hospital thromboprophylaxis group (hazard ratio 1.12; 95% confidence interval 0.72 to 1.76; P=0.1). CONCLUSIONS: Extended duration to perioperative anticoagulation with tinzaparin did not improve disease-free survival or overall survival in patients with colorectal cancer undergoing surgical resection compared with in-patient postoperative thromboprophylaxis alone. The incidences of venous thromboembolism and postoperative major bleeding were low and similar between groups. TRIAL REGISTRATION: ClinicalTrials.gov NCT01455831.

BACKGROUND: Preoperative frailty is associated with increased risk of postoperative mortality and complications. Routine preoperative frailty assessment is underperformed. Automation of preoperative frailty assessment using electronic health data could improve adherence to guideline-based care if an accurate instrument is identified. METHODS: We conducted a retrospective cohort study of adults >65 yr undergoing elective noncardiac surgery between 2012 and 2018. Four frailty instruments were compared: Frailty Index, Hospital Frailty Risk Score, Risk Analysis Index-Administrative, and Adjusted Clinical Groups frailty-defining diagnoses indicator. We compared the predictive performance of each instrument added to a baseline model (age, sex, ASA physical status, and procedural risk) using discrimination, calibration, explained variance, net reclassification, and Brier score (binary outcomes); and explained variance, root mean squared error, and mean absolute prediction error (continuous outcomes). Primary outcome was 30-day mortality. Secondary outcomes included 365-day mortality, length of stay, non-home discharge, days alive at home, and 365-day costs. RESULTS: For this study, 171 576 patients met the inclusion criteria; 1370 (0.8%) died within 30 days. Compared with the baseline model predicting 30-day mortality (area under the curve [AUC] 0.85; R2 0.08), the addition of Hospital Frailty Risk Score led to the greatest improvement in discrimination (AUC 0.87), explained variance (R2 0.09), and net reclassification (Net Reclassification Index 0.65). Brier and calibration scores were comparable. CONCLUSIONS: All four frailty instruments significantly improved discrimination and risk reclassification when added to typically assessed preoperative risk factors. Accurate identification of the presence or absence of preoperative frailty using electronic frailty instruments may improve perioperative risk stratification. Future research should evaluate the impact of automated frailty assessment in guiding surgical planning and patient-centred optimisation amongst older surgical patients.

BACKGROUND: Patients with anemia undergoing elective colorectal cancer surgery are known to have significantly higher rates of postoperative complications and worse outcomes. OBJECTIVE: This study aimed to improve rates of anemia screening and treatment in patients undergoing elective colon and rectal resections through a quality improvement initiative. DESIGN: We compared a historical cohort of patients before implementation of our anemia screening and treatment quality improvement program to a prospective cohort after implementation. SETTINGS: This study was conducted at a tertiary care hospital. PATIENTS: This study included all adult patients with a new diagnosis of colon or rectal cancer without evidence of metastatic disease between 2017 and 2019. INTERVENTIONS: The interventions include the anemia screening and treatment quality improvement program. MAIN OUTCOME MEASURES: The primary outcome was hospital cost per admission. RESULTS: This study includes a total of 84 patients who underwent elective colon or rectal resection before implementation of our anemia quality improvement project and 88 patients who underwent surgery after. In the preimplementation cohort 44 of 84 patients (55.9%) were anemic compared to 47 of 99 patients (54.7%) in the postimplementation cohort. Rates of screening (25%-86.4%) and treatment (27.8%- 63.8%) were significantly increased in the postimplementation cohort. Mean total cost per admission was significantly decreased in the postimplementation cohort (mean cost $16,827 vs $25,796; p = 0.004); this significant reduction was observed even after adjusting for relevant confounding factors (ratio of means: 0.74; 95% CI, 0.65-0.85). The mechanistic link between treatment of anemia and reductions in cost remains unknown. No significant difference was found in rates of blood transfusion, complications, or mortality between the groups. LIMITATIONS: The study limitation includes before-after design subjected to selection and temporal biases. CONCLUSIONS: We demonstrate the successful implementation of an anemia screening and treatment program. This program was associated with significantly reduced cost per admission. This work demonstrates possible value and benefits of implementation of an anemia screening and treatment program.

ANTECEDENTES: Se sabe que los pacientes anémicos que se someten a una cirugía electiva de cáncer colorrectal tienen tasas significativamente más altas de complicaciones posoperatorias y peores resultados. OBJETIVO: Mejorar las tasas de detección y tratamiento de la anemia en pacientes sometidos a resecciones electivas de colon y recto a través de una iniciativa de mejora de calidad. DISEO: Comparamos una cohorte histórica de pacientes antes de la implementación de nuestro programa de detección de anemia y mejora de la calidad del tratamiento con una cohorte prospectiva después de la implementación. ENTORNO CLINICO: Hospital de atención terciaria. PACIENTES: Todos los pacientes adultos con un nuevo diagnóstico de cáncer de colon o recto sin evidencia de enfermedad metastásica entre 2017 y 2019. INTERVENCIONES: Detección de anemia y programa de mejora de la calidad del tratamiento. PRINCIPALES MEDIDAS DE RESULTADO: El resultado primario fue el costo hospitalario por ingreso. RESULTADOS: Un total de 84 pacientes se sometieron a resección electiva de colon o recto antes de la implementación de nuestro proyecto de mejora de calidad de la anemia y 88 pacientes se sometieron a cirugía después. En la cohorte previa a la implementación, 44/84 (55,9 %) presentaban anemia en comparación con 47/99 (54,7 %) en la cohorte posterior a la implementación. Las tasas de detección (25 % a 86,4 %) y tratamiento (27,8 % a 63,8 %) aumentaron significativamente en la cohorte posterior a la implementación. El costo total medio por admisión se redujo significativamente en la cohorte posterior a la implementación (costo medio $16 827 vs. $25 796, p = 0,004); esta reducción significativa se observó incluso después de ajustar los factores de confusión relevantes (proporción de medias: 0,74, IC del 95 %: 0,65 a 0,85). El vínculo mecánico entre el tratamiento de la anemia y la reducción de costos sigue siendo desconocido. No hubo diferencias significativas en las tasas de transfusión de sangre, complicaciones o mortalidad entre los grupos. LIMITACIONES: El diseño de antes y después está sujeto a sesgos temporales y de selección. CONCLUSIONES: Demostramos la implementación exitosa de un programa de detección y tratamiento de anemia. Este programa se asoció con un costo por admisión significativamente reducido. Este trabajo demuestra el valor y los beneficios posibles de la implementación de un programa de detección y tratamiento de la anemia. Consulte Video Resumen en http://links.lww.com/DCR/C15 .

PURPOSE: Preoperative frailty assessment is recommended by multiple practice guidelines and may improve outcomes, but it is not routinely performed. The barriers and facilitators of routine preoperative frailty assessment have not been formally assessed. Our objective was to perform a theory-guided evaluation of barriers and facilitators to preoperative frailty assessment. METHODS: This was a research ethics board-approved qualitative study involving physicians who perform preoperative assessment (consultant and resident anesthesiologists and consultant surgeons). Semistructured interviews were conducted by a trained research assistant informed by the Theoretical Domains Framework to identify barriers and facilitators to frailty assessment. Interview transcripts were independently coded by two research assistants to identify specific beliefs relevant to each theoretical domain. RESULTS: We interviewed 28 clinicians (nine consultant anesthesiologists, nine consultant surgeons, and ten anesthesiology residents). Six domains (Knowledge [100%], Social Influences [96%], Social Professional Role and Identity [96%], Beliefs about Capabilities [93%], Goals [93%], and Intentions [93%]) were identified by > 90% of respondents. The most common barriers identified were prioritization of other aspects of assessment (e.g., cardio/respiratory) and a lack of awareness of evidence and guidelines supporting frailty assessment. The most common facilitators were a high degree of familiarity with frailty, recognition of the importance of frailty assessment, and strong intentions to perform frailty assessment. CONCLUSION: Barriers and facilitators to preoperative frailty assessment are multidimensional, but generally consistent across different types of perioperative physicians. Knowledge of barriers and facilitators can guide development of evidence-based strategies to increase frailty assessment.
RéSUMé: OBJECTIF: L'évaluation préopératoire de la fragilité est recommandée par plusieurs lignes directrices de pratique et pourrait améliorer les devenirs, mais elle n'est pas systématiquement réalisée. Les obstacles et les facilitateurs de l'évaluation de routine de la fragilité préopératoire n'ont pas été officiellement évalués. Notre objectif était de mener une évaluation théorique des obstacles et des facilitateurs de l'évaluation préopératoire de la fragilité. MéTHODE: Il s'agissait d'une étude qualitative approuvée par le comité d'éthique de la recherche impliquant des médecins menant des évaluations préopératoires (anesthésiologistes, résidents en anesthésiologie et chirurgiens). Des entrevues semi-structurées ont été réalisées par un assistant de recherche formé en se fondant sur le Cadre des domaines théoriques afin d'identifier les obstacles et les facilitateurs à l'évaluation de la fragilité. Les transcriptions des entrevues ont été codées de manière indépendante par deux assistants de recherche afin d'identifier les croyances spécifiques pertinentes à chaque domaine théorique. RéSULTATS: Nous avons interrogé 28 cliniciens (neuf anesthésiologistes, neuf chirurgiens et dix résidents en anesthésiologie). Six domaines (Connaissances [100 %], Influences sociales [96 %], Rôle et identité socio-professionnels [96 %], Croyances concernant les capacités [93 %], Objectifs [93 %] et Intentions [93 %]) ont été identifiés par > 90 % des répondants. Les obstacles les plus fréquemment cités étaient la priorisation accordée à d'autres aspects de l'évaluation (p. ex., cardio/respiratoire) et le manque de connaissances des données probantes et des lignes directrices à l'appui de l'évaluation de la fragilité. Les facilitateurs les plus courants étaient un degré élevé de familiarité avec la fragilité, la reconnaissance de l'importance de l'évaluation de la fragilité et de fortes intentions de réaliser une évaluation de la fragilité. CONCLUSION: Les obstacles et les facilitateurs de l'évaluation préopératoire de la fragilité sont multidimensionnels, mais généralement uniformes parmi les différents types de médecins périopératoires. La connaissance des obstacles et des facilitateurs peut guider l'élaboration de stratégies fondées sur des données probantes pour augmenter l'évaluation de la fragilité.
