Educational outcomes of simulation-based training in regional anaesthesia: a scoping review.

BACKGROUND: Structured training in regional anaesthesia includes pretraining on simulation-based educational platforms to establish a safe and controlled learning environment before learners are provided clinical exposure in an apprenticeship model. This scoping review was designed to appraise the educational outcomes of current simulation-based educational modalities in regional anaesthesia. METHODS: This review conformed to PRISMA-ScR guidelines. Relevant articles were searched in PubMed, Scopus, Google Scholar, Web of Science, and EMBASE with no date restrictions, until November 2023. Studies included randomised controlled trials, pre-post intervention, time series, case control, case series, and longitudinal studies, with no restrictions to settings, language or ethnic groups. The Kirkpatrick framework was applied for extraction of educational outcomes. RESULTS: We included 28 studies, ranging from 2009 to 2023, of which 46.4% were randomised controlled trials. The majority of the target population was identified as trainees or residents (46.4%). Higher order educational outcomes that appraised translation to real clinical contexts (Kirkpatrick 3 and above) were reported in 12 studies (42.9%). Two studies demonstrated translational patient outcomes (Level 4) with reduced incidence of paraesthesia and clinical complications. The majority of studies appraised Level 3 outcomes of performance improvements in either laboratory simulation contexts (42.9%) or demonstration of clinical performance improvements in regional anaesthesia (39.3%). CONCLUSIONS: There was significant heterogeneity in the types of simulation modalities used, teaching interventions applied, study methodologies, assessment tools, and outcome measures studied. When improvisations were made to regional anaesthesia simulation platforms (hybrid simulation), there were sustained educational improvements beyond 6 months. Newer technology-enhanced innovations such as virtual, augmented, and mixed reality simulations are evolving, with early reports of educational effectiveness.

Simulation-based ultrasound-guided regional anesthesia education: a national survey of Canadian anesthesiology residency training programs.

PURPOSE: Simulation-based education in ultrasound-guided regional anesthesia (UGRA) improves knowledge, skills, and patient outcomes. Nevertheless, it is not known how simulation-based UGRA education is used across Canada. We aimed to characterize the current use of simulation-based UGRA education in Canadian anesthesiology residency training programs. METHODS: We developed and distributed a structured national survey to simulation leads of all 17 Canadian anesthesiology residency training programs. The survey inquired about program demographics, simulation modalities, facilitators and barriers to simulation use, use for assessment, and beliefs around simulation-based UGRA education. We gathered data from August to November 2023 and summarized our findings descriptively. RESULTS: Fifteen programs (88%) responded to our survey. Eight programs (53%) used UGRA simulation for technical training and nine programs (60%) for nontechnical training. The most common simulators used were live model scanning (13 programs, 87%) and gel phantom models (7 programs, 47%). Five programs (33%) mandated simulation-based UGRA in their curriculum. We found that deliberate practice and improved patient safety were most valued in simulation training while lack of funding and faculty availability were the most common barriers to implementation. Most respondents agreed that formative simulation-based education would improve trainee skills and called for greater standardization. Nevertheless, there were mixed responses regarding summative UGRA simulation and the need for simulation proficiency before clinical practice. CONCLUSIONS: Our findings show significant variations in simulation implementation and views on UGRA simulation-based education among Canadian anesthesiology residency training programs. Future studies should explore avenues to overcome barriers and improve knowledge translation in UGRA.

RéSUMé: OBJECTIF: La formation basée sur la simulation en anesthésie régionale échoguidée améliore les connaissances, les compétences et les issues pour les patient·es. Néanmoins, on ne sait pas comment la formation en AR échoguidée basée sur la simulation est utilisée au Canada. Nous avons cherché à caractériser l'utilisation actuelle de l'enseignement de l'AR échoguidée basée sur la simulation dans les programmes canadiens de résidence en anesthésiologie. MéTHODE: Nous avons élaboré et distribué un sondage national structuré aux responsables de la simulation des 17 programmes canadiens de résidence en anesthésiologie. L'enquête portait sur les données démographiques du programme, les modalités de simulation, les facilitateurs et les obstacles à l'utilisation de la simulation, son utilisation pour l'évaluation, et les croyances concernant l'éducation en AR échoguidée basée sur la simulation. Nous avons recueilli des données d'août à novembre 2023 et résumé nos résultats de manière descriptive. RéSULTATS: Quinze programmes (88 %) ont répondu à notre sondage. Huit programmes (53 %) utilisent la simulation en AR échoguidée pour la formation technique et neuf programmes (60 %) pour la formation non technique. Les simulateurs les plus couramment utilisés étaient le balayage sur modèles vivants (13 programmes, 87 %) et les modèles de fantômes en gel (7 programmes, 47 %). Cinq programmes (33 %) ont rendu obligatoire l'AR échoguidée basée sur la simulation dans leur programme. Nous avons constaté que la pratique délibérée et l'amélioration de la sécurité des patient·es étaient les plus appréciées dans la formation par simulation, tandis que le manque de financement et la disponibilité du corps professoral étaient les obstacles les plus courants à la mise en œuvre. La plupart des répondant·es ont convenu que l'éducation formative basée sur la simulation améliorerait les compétences des stagiaires et ont appelé à une plus grande standardisation. Néanmoins, les réponses étaient mitigées concernant la simulation sommative en AR échoguidée et la nécessité d'une maîtrise de la simulation avant la pratique clinique. CONCLUSION: Nos résultats montrent des variations significatives dans la mise en œuvre de la simulation et les points de vue sur l'éducation basée sur la simulation en AR échoguidée parmi les programmes canadiens de résidence en anesthésiologie. Les études futures devraient explorer les moyens de surmonter les obstacles et d'améliorer l'application des connaissances à l'anesthésie régionale échoguidée.

A quasi-experimental evaluation of the association between implementation of Quality-Based Procedures funding for hip fractures and improvements in processes and outcomes for hip fracture patients in Ontario: an interrupted time series analysis.

PURPOSE: In 2013, Ontario introduced a patient-based funding model for hip fracture care (Quality-Based Procedures [QBP]). The association of QBP implementation with changes in processes and outcomes has not been evaluated. METHODS: We conducted a quasi-experimental study using linked health data for adult hip fractures as an interrupted time series. The pre-QBP period was from 2008 to 2012 and the post-QBP period was from 2014 to 2018; 2013 was excluded as a wash-in period. We used segmented regression analyses to estimate the association of QBP implementation with changes in processes (surgery in less than two days from admission, use of echocardiography, use of nerve blocks, and provision of geriatric care) and clinical outcomes (90-day mortality, 90-day readmissions, length of stay, and days alive at home). We estimated the immediate (level) change, trend (slope) postimplementation, and total counterfactual differences. Sensitivity analyses included case-mix adjustment and stratification by hospital type and procedure. RESULTS: We identified 45,500 patients in the pre-QBP period and 41,256 patients in the post-QBP period. There was a significant total counterfactual increase in the use of nerve blocks (11.1%; 95% confidence interval [CI], 6.2 to 16.0) and a decrease in the use of echocardiography (-2.5%; 95% CI, -3.7 to -1.3) after QBP implementation. The implementation of QBP was not associated with a clinically or statistically meaningful change in 90-day mortality, 90-day readmission, length of stay, or number of days alive at home. CONCLUSION: Evaluation of the QBP program is crucial to inform ongoing and future changes to policy and funding for hip fracture care. The introduction of the QBP Hip Fracture program, supported by evidence-based recommendations, was associated with improved application of some evidence-based processes of care but no changes in clinical outcomes. There is a need for ongoing development and evaluation of funding models to identify optimal strategies to improve the value and outcomes of hip fracture care.

RéSUMé: OBJECTIF: En 2013, l'Ontario a mis en place un modèle de financement axé sur les patient·es pour les soins suivant une fracture de la hanche (procédures fondées sur la qualité [PFQ]). L'association entre la mise en œuvre des PFQ et les changements dans les processus et les devenirs n'a pas été évaluée. MéTHODE: Nous avons mené une étude quasi expérimentale en utilisant des données de santé couplées pour les fractures de la hanche chez l'adulte comme une série chronologique interrompue. La période précédant les PFQ s'étendait de 2008 à 2012, et la période subséquente à l'implantation des PFQ allait de 2014 à 2018. L'année 2013 a été exclue en tant que période de rodage. Nous avons utilisé des analyses de régression segmentées pour estimer l'association entre la mise en œuvre des PFQ avec des changements aux processus (chirurgie en moins que deux jours suivant l'admission, utilisation de l'échocardiographie, utilisation de blocs nerveux et prestation de soins gériatriques) et des issues cliniques (mortalité à 90 jours, réadmissions à 90 jours, durée de séjour et jours de vie à domicile). Nous avons estimé le changement immédiat (niveau), la tendance (pente) après la mise en œuvre et les différences contrefactuelles totales. Les analyses de sensibilité comprenaient l'ajustement et la stratification de la combinaison de cas par type d'hôpital et par procédure. RéSULTATS: Nous avons identifié 45 500 patient·es dans la période pré-PFQ et 41 256 patient·es dans la période post-PFQ. Il y a eu une augmentation contrefactuelle totale significative de l'utilisation de blocs nerveux (11,1 %; intervalle de confiance [IC] à 95 %, 6,2 à 16,0) et une diminution de l'utilisation de l'échocardiographie (−2,5 %; IC 95 %, −3,7 à −1,3) après la mise en œuvre des PFQ. La mise en œuvre des PFQ n'a pas été associée à un changement cliniquement ou statistiquement significatif de la mortalité à 90 jours, de la réadmission à 90 jours, de la durée de séjour ou du nombre de jours de vie à domicile. CONCLUSION: L'évaluation du programme de PFQ est cruciale pour guider les changements actuels et futurs aux politiques et au financement des soins suivant une fracture de la hanche. La mise en place du programme de PFQ pour les fractures de la hanche, appuyée par des recommandations fondées sur des données probantes, a été associée à une meilleure application de certains processus de soins fondés sur des données probantes, mais à aucun changement dans les devenirs cliniques. Il est nécessaire d'élaborer et d'évaluer continuellement des modèles de financement afin de déterminer les stratégies optimales pour améliorer la valeur et les devenirs des soins suivant une fracture de la hanche.

Hospital-, anaesthetist-, and patient-level variation in peripheral nerve block utilisation for hip fracture surgery: a population-based cross-sectional study.

BACKGROUND: Unwarranted variation in anaesthesia practice is associated with adverse outcomes. Despite high-certainty evidence of benefit, a minority of hip fracture surgery patients receive a peripheral nerve block. Our objective was to estimate variation in peripheral nerve block use at the hospital, anaesthetist, and patient levels, while identifying predictors of peripheral nerve block use in hip fracture patients. METHODS: After protocol registration (https://osf.io/48bvp/), we conducted a population-based cross-sectional study using linked administrative data in Ontario, Canada. We included adults >65 yr of age having emergency hip fracture surgery from April 1, 2012 to March 31, 2018. Logistic mixed models were used to estimate the variation in peripheral nerve block use attributable to hospital-, anaesthetist-, and patient-level factors with use of peripheral nerve block, quantified using the variance partition coefficient and median odds ratio. Predictors of peripheral nerve block use were estimated and temporally validated. RESULTS: Of 50 950 patients, 9144 (18.5%) received a peripheral nerve block within 1 day of surgery. Patient-level factors accounted for 14% of variation, whereas 42% and 44% were attributable to the hospital and anaesthetist providing care, respectively. The median odds ratio for receiving a peripheral nerve block was 5.73 at the hospital level and 5.97 at the anaesthetist level. No patient factors had large associations with receipt of a peripheral nerve block (odds ratios significant at the 5% level ranged from 0.86 to 1.35). CONCLUSIONS: Patient factors explain the minimal variation in peripheral nerve block use for hip fracture surgery. Interventions to increase uptake of peripheral nerve blocks for hip fracture patients will likely need to focus on structures and processes at the hospital and anaesthetist levels.

Persistent Postoperative Opioid Prescription Fulfillment and Peripheral Nerve Blocks for Ambulatory Shoulder Surgery: A Retrospective Cohort Study.

BACKGROUND: There is need to identify perioperative interventions that decrease chronic opioid use. The authors hypothesized that receipt of a peripheral nerve block would be associated with a lower incidence of persistent postoperative opioid prescription fulfillment. METHODS: This was a retrospective population-based cohort study examining ambulatory shoulder surgery patients in Ontario, Canada. The main outcome measure was persistent postoperative opioid prescription fulfillment. In opioid-naive patients (no opioid prescription fulfillment in 90 days preoperatively), this was present if an individual fulfilled an opioid prescription of at least a 60-day supply during postoperative days 90 to 365. In opioid-exposed (less than 60 mg oral morphine equivalent dose per day within 90 days preoperatively) or opioid-tolerant (60 mg oral morphine equivalent dose per day or above within 90 days preoperatively) patients, this was classified as present if an individual experienced any increase in opioid prescription fulfillment from postoperative day 90 to 365 relative to their baseline use before surgery. The authors' exposure was the receipt of a peripheral nerve block. RESULTS: The authors identified 48,523 people who underwent elective shoulder surgery from July 1, 2012, to December 31, 2017, at one of 118 Ontario hospitals. There were 8,229 (17%) patients who had persistent postoperative opioid prescription fulfillment. Of those who received a peripheral nerve block, 5,008 (16%) went on to persistent postoperative opioid prescription fulfillment compared to 3,221 (18%) patients who did not (adjusted odds ratio, 0.90; 95% CI, 0.83 to 0.97; P = 0.007). This statistically significant observation was not reproduced in a coarsened exact matching sensitivity analysis (adjusted odds ratio, 0.85; 95% CI, 0.71 to 1.02; P = 0.087) or several other subgroup and sensitivity analyses. CONCLUSIONS: This retrospective analysis found no association between receipt of a peripheral nerve block and a lower incidence of persistent postoperative opioid prescription fulfillment in ambulatory shoulder surgery patients.

Peripheral Nerve Blocks and Potentially Attributable Adverse Events in Older People with Hip Fracture: A Retrospective Population-based Cohort Study.

BACKGROUND: Peripheral nerve blocks are being used with increasing frequency for management of hip fracture-related pain. Despite converging evidence that nerve blocks may be beneficial, safety data are lacking. This study hypothesized that peripheral nerve block receipt would not be associated with adverse events potentially attributable to nerve blocks, as well as overall patient safety incidents while in hospital. METHODS: This was a preregistered, retrospective population-based cohort study using linked administrative data. This study identified all hip fracture admissions in people 50 yr of age or older and identified all nerve blocks (although we were unable to ascertain the specific anatomic location or type of block), potentially attributable adverse events (composite of seizures, fall-related injuries, cardiac arrest, nerve injury), and any patient safety events using validated codes. The study also estimated the unadjusted and adjusted association of nerve blocks with adverse events; adjusted absolute risk differences were also calculated. RESULTS: In total, 91,563 hip fracture patients from 2009 to 2017 were identified; 15,631 (17.1%) received a nerve block, and 5,321 (5.8%; 95% CI, 5.7 to 6.0%) patients experienced a potentially nerve block-attributable adverse event: 866 (5.5%) in patients with a block and 4,455 (5.9%) without a block. Before and after adjustment, nerve blocks were not associated with potentially attributable adverse events (adjusted odds ratio, 1.05; 95% CI, 0.97 to 1.15; and adjusted risk difference, 0.3%, 95% CI, -0.1 to 0.8). CONCLUSIONS: The data suggest that nerve blocks in hip fracture patients are not associated with higher rates of potentially nerve block-attributable adverse events, although these findings may be influenced by limitations in routinely collected administrative data.

Peripheral Nerve Blocks for Ambulatory Shoulder Surgery: A Population-based Cohort Study of Outcomes and Resource Utilization.

BACKGROUND: Nerve blocks improve early pain after ambulatory shoulder surgery; impact on postdischarge outcomes is poorly described. Our objective was to measure the association between nerve blocks and health system outcomes after ambulatory shoulder surgery. METHODS: We conducted a population-based cohort study using linked administrative data from 118 hospitals in Ontario, Canada. Adults having elective ambulatory shoulder surgery (open or arthroscopic) from April 1, 2009, to December 31, 2016, were included. After validation of physician billing codes to identify nerve blocks, we used multilevel, multivariable regression to estimate the association of nerve blocks with a composite of unplanned admissions, emergency department visits, readmissions or death within 7 days of surgery (primary outcome) and healthcare costs (secondary outcome). Neurology consultations and nerve conduction studies were measured as safety indicators. RESULTS: We included 59,644 patients; blocks were placed in 31,073 (52.1%). Billing codes accurately identified blocks (positive likelihood ratio 16.83, negative likelihood ratio 0.03). The composite outcome was not significantly different in patients with a block compared with those without (2,808 [9.0%] vs. 3,424 [12.0%]; adjusted odds ratio 0.96; 95% CI 0.89 to 1.03; P = 0.243). Healthcare costs were greater with a block (adjusted ratio of means 1.06; 95% CI 1.02 to 1.10; absolute increase $325; 95% CI $316 to $333; P = 0.005). Prespecified sensitivity analyses supported these results. Safety indicators were not different between groups. CONCLUSIONS: In ambulatory shoulder surgery, nerve blocks were not associated with a significant difference in adverse postoperative outcomes. Costs were statistically higher with a block, but this increase is not likely clinically relevant.

A Population-based Comparative Effectiveness Study of Peripheral Nerve Blocks for Hip Fracture Surgery.

BACKGROUND: Adverse outcomes and resource use rates are high after hip fracture surgery. Peripheral nerve blocks could improve outcomes through enhanced analgesia and decreased opioid related adverse events. We hypothesized that these benefits would translate into decreased resource use (length of stay [primary outcome] and costs), and better clinical outcomes (pneumonia and mortality). METHODS: The authors conducted a retrospective cohort study of hip fracture surgery patients in Ontario, Canada (2011 to 2015) using linked health administrative data. Multilevel regression, instrumental variable, and propensity scores were used to determine the association of nerve blocks with resource use and outcomes. RESULTS: The authors identified 65,271 hip fracture surgery patients; 10,030 (15.4%) received a block. With a block, the median hospital stay was 7 (interquartile range, 4 to 13) days versus 8 (interquartile range, 5 to 14) days without. Following adjustment, nerve blocks were associated with a 0.6-day decrease in length of stay (95% CI, 0.5 to 0.8). This small difference was consistent with instrumental variable (1.1 days; 95% CI, 0.9 to 1.2) and propensity score (0.2 days; 95% CI, 0.2 to 0.3) analyses. Costs were lower with a nerve block (adjusted difference, -$1,421; 95% CI, -$1,579 to -$1,289 [Canadian dollars]), but no difference in mortality (adjusted odds ratio, 0.99; 95% CI, 0.89 to 1.11) or pneumonia (adjusted odds ratio, 1.01; 95% CI, 0.88 to 1.16) was observed. CONCLUSIONS: Receipt of nerve blocks for hip fracture surgery is associated with decreased length of stay and health system costs, although small effect sizes may not reflect clinical significance for length of stay.
