Postdischarge opioid use after lumbar spine surgery among older adults in Ontario: a population-based cohort study.

BACKGROUND: Prescription opioid use places a considerable economic burden on health care systems. Older patients undergoing surgical procedures for painful conditions commonly receive opioids pre- and postoperatively, and are susceptible to adverse reactions. This study explores predictors of prolonged postoperative opioid use among older patients after lumbar spine surgery and the consequences in terms of health care utilization and costs. METHODS: We conducted a retrospective population-based cohort study using Ontario administrative data from older adults undergoing spine surgery between 2006 and 2017. Data were analyzed from 90 days preoperatively to 1 year after hospital discharge, with last postoperative opioid prescriptions stratified into 90-day increments. We used multivariable ordinal logistic regression to identify predictors of long-term opioid use and generalized linear modelling to examine resource utilization and health care costs (2021 Canadian dollars). RESULTS: Of 15 109 patients included, 40.8% received preoperative opioid prescriptions. Preoperative opioid use strongly predicted prolonged postoperative use (odds ratio [OR] 4.47, 95% confidence interval [CI] 4.16-4.79), with 48.3% of patients who received preoperative opioids continuing to use opioids for longer than 9 months, relative to 12.7% of those without preoperative use. Several other risk factors for prolonged use were identified. Patients receiving long-term postoperative opioids incurred greater health care costs relative to those with opioids prescribed for fewer than 90 days (OR 1.49, 95% CI 1.44-1.54). CONCLUSION: Among older adults undergoing spine surgery, preoperative opioid use was a strong predictor of prolonged postoperative use, which was associated with increased health care costs. These results form an important baseline for future studies evaluating strategies to reduce opioid use targeting older surgical populations.

Was it all worth it? A graduating resident perspective on CBME.

BACKGROUND: Our institution simultaneously transitioned all postgraduate specialty training programs to competency-based medical education (CBME) curricula. We explored experiences of CBME-trained residents graduating from five-year programs to inform the continued evolution of CBME in Canada. METHODS: We utilized qualitative description to explore residents' experiences and inform continued CBME improvement. Data were collected from fifteen residents from various specialties through focus groups, interviews, and written responses. The data were analyzed inductively, using conventional content analysis. RESULTS: We identified five overarching themes. Three themes provided insight into residents' experiences with CBME, describing discrepancies between the intentions of CBME and how it was enacted, challenges with implementation, and variation in residents' experiences. Two themes - adaptations and recommendations - could inform meaningful refinements for CBME going forward. CONCLUSIONS: Residents graduating from CBME training programs offered a balanced perspective, including criticism and recognition of the potential value of CBME when implemented as intended. Their experiences provide a better understanding of residents' needs within CBME curricula, including greater balance and flexibility within programs of assessment and curricula. Many challenges that residents faced with CBME could be alleviated by greater accountability at program, institutional, and national levels. We conclude with actionable recommendations for addressing residents' needs in CBME.

Evaluating the Quality of Narrative Feedback for Entrustable Professional Activities in a Surgery Residency Program.

OBJECTIVE: We assessed the quality of narrative feedback given to surgical residents during the first five years of Competency-Based Medical Education (CBME) implementation. SUMMARY BACKGROUND DATA: CBME requires ongoing formative assessments and feedback on learners' performance. METHODS: We conducted a retrospective cross-sectional study using assessments of Entrustable Professional Activities (EPAs) in the Surgical Foundations curriculum at Queen's University from 2017-2022. Two raters independently evaluated quality of narrative feedback using the Quality of Assessment of Learning (QuAL) Score (0-5). RESULTS: A total of 3,900 EPA assessments were completed over 5 years. Fifty-seven percent (2229/3900) of assessments had narrative feedback documented with a mean QuAL score of 2.16±1.49. Of these, 1614 (72.4%) provided evidence about the resident's performance, 951 (42.7%) provided suggestions for improvement, and 499/2229 (22.4%) connected suggestions to the evidence. There was no meaningful change in narrative feedback quality over time (r=0.067, P=0.002). Variables associated with lower quality of narrative feedback include: Attending role (2.04±1.48) compared to medical student (3.13±1.12, P<0.001) and clinical fellow (2.47±1.54, P<0.001), concordant specialties between the assessor and learner (2.06±1.50 vs. 2.21±1.49, P=0.025), completion of the assessment one month or more after the encounter versus one week (1.85±1.48 vs. 2.23±1.49, P<0.001), and resident entrustment versus not entrusted to perform the assessed EPA (2.13±1.45 vs. 2.35±1.66; P=0.008). The quality of narrative feedback was similar for assessments completed under direct and indirect observation (2.18±1.47 vs. 2.06±1.54; P=0.153). CONCLUSIONS: Just over half of the EPA assessments of surgery residents contained narrative feedback with overall fair quality. There was no meaningful change in the quality of feedback over 5 years. These findings prompt future research and faculty development.

Exploring residents' perceptions of competency-based medical education across Canada: A national survey study.

Background: As competency-based medical education (CBME) is implemented across Canada, little is known about residents' perceptions of this model. This study examined how Canadian residents understand CBME and their lived experiences with implementation. Methods: We administered a survey in 2018 with Likert-type and open-ended questions to 375 residents across Canada, of whom 270 were from traditional programs ("pre-CBME") and 105 were in a CBME program. We used the Mann-Whitney test to examine differences across samples, and analyzed qualitative data thematically. Results: Three themes were identified across both groups: program outcome concerns, changes, and emotional responses. In relation to program concerns, both groups were concerned about the administrative burden, challenges with the assessment process, and feedback quality. Only pre-CBME residents were concerned about faculty engagement and buy-in. In terms of changes, both groups discussed a more formalized assessment process with mixed reactions. Residents in the pre-CBME sample reported greater concerns for faculty time constraints, assessment completion, and quality of learning experiences, whilst those in CBME programs reported being more proactive in their learning and greater selfreflection. Residents expressed strong emotional narrative responses including greater stress and frustration in a CBME environment. Conclusion: Findings demonstrate that residents have mixed feelings and experiences regarding CBME. Their positive experiences align with the aim of developing more self-directed learners. However, the concerns suggest the need to address specific shortcomings to increase buy-in, while the emotional responses associated with CBME may require a cultural shift within residency programs to guard against burnout.

Inadequacies in Undergraduate Musculoskeletal Education-A Survey of Nationally Accredited Allopathic Medical Programs in Canada.

OBJECTIVE: The aim of the study is to document the current state of musculoskeletal (MSK) medicine education across nationally accredited undergraduate medical programs. DESIGN: A cross-sectional survey design was used to gather curricular data on the following three musculoskeletal themes: (1) anatomy education, (2) preclinical education, and (3) clerkship education. RESULTS: The survey had a 100% response rate with all 14 English-language medical schools in Canada responding. The mean time spent teaching musculoskeletal anatomy was 29.8 hrs (SD ± 13.7, range = 12-60), with all but one program using some form of cadaveric-based instruction. Musculoskeletal preclinical curricula averaged 58.0 hrs (SD ± 53.4, range = 6-204), with didactic lectures, case-based learning, and small group tutorials being the most common modes of instruction. Curricular content varied greatly, with only 25% of "core or must-know" musculoskeletal topics being covered in detail by all programs. Musculoskeletal training in clerkship was required by only 50% of programs, most commonly being 2 wks in duration. CONCLUSIONS: Results document the large variability and curricular inadequacies that exist in musculoskeletal education across nationally accredited allopathic programs and highlight the need for the identification and implementation of more consistent musculoskeletal curricular content and educational standards by all nationally accredited medical programs.

Utility of routine postoperative chest radiography in patients undergoing clavicle fixation: a retrospective chart review.

BACKGROUND: Although uncommon, pneumothorax is a potentially serious complication following open reduction and internal fixation (ORIF) of clavicle fractures. In many centres it is routine practice to obtain postoperative chest radiographs following ORIF of clavicle fractures to assess for iatrogenic pneumothorax. Given the need to contain health care costs, the low sensitivity for detecting small pneumothorax and a desire to decrease patient radiation exposure, the practice of ordering chest radiographs following ORIF of clavicle fractures may be unnecessary. METHODS: All patients undergoing ORIF of clavicle fractures with plate and screw fixation at Kingston Health Sciences Centre between April 2009 and June 2020 were identified from the Discharge Abstract Database (inpatient) and National Ambulatory Care Reporting System (outpatient) using relevant Canadian Classification of Health Intervention procedure codes. Charts were manually reviewed to confirm diagnosis and procedure, and patients with preoperative pneumothorax were excluded. The frequency of postoperative chest radiograph and pneumothorax detection were calculated. RESULTS: Among the 292 patients who underwent ORIF of clavicle fractures during the study period, 17 were excluded for having a pneumothorax on preoperative chest radiograph. Of the remaining 275 patients, 101 (36.7%) had postoperative chest radiographs, of whom none were found to have postoperative iatrogenic pneumothorax. CONCLUSION: Since 2009, the rate of routine postoperative chest radiography following ORIF of clavicle fractures is 36.7% at our centre. During this time period, none of the 101 patients who had postoperative chest radiographs had a postoperative iatrogenic pneumothorax. To our knowledge, this is the largest series of patients available, and our findings confirm those of several smaller studies. Owing to the low rate of postoperative iatrogenic pneumothorax, we conclude that postoperative chest radiography is unnecessary following ORIF of clavicle fractures.

Exploring the Quality of Narrative Feedback Provided to Residents During Ambulatory Patient Care in Medicine and Surgery.

OBJECTIVES: The transition to competency-based medical education (CBME) has increased the volume of residents' assessment data; however, the quality of the narrative feedback is yet to be used as feedback-on-feedback for faculty. Our objectives were (1) to explore and compare the quality and content of narrative feedback provided to residents in medicine and surgery during ambulatory patient care and (2) to use the Deliberately Developmental Organization framework to identify strengths, weaknesses, and opportunities to improve quality of feedback within CBME. METHODS: We conducted a mixed convergent methods study with residents from the Departments of Surgery (DoS; n = 7) and Medicine (DoM; n = 9) at Queen's University. We used thematic analysis and the Quality of Assessment for Learning (QuAL) tool to analyze the content and quality of narrative feedback documented in entrustable professional activities (EPAs) assessments for ambulatory care. We also examined the association between the basis of assessment, time to provide feedback, and the quality of narrative feedback. RESULTS: Forty-one EPA assessments were included in the analysis. Three major themes arose from thematic analysis: Communication, Diagnostics/Management, and Next Steps. Quality of the narrative feedback varied; 46% had sufficient evidence about residents' performance; 39% provided a suggestion for improvement; and 11% provided a connection between the suggestion and the evidence. There were significant differences between DoM and DoS in quality of feedback scores for evidence (2.1 [1.3] vs. 1.3 [1.1]; p < 0.01) and connection (0.4 [0.5] vs. 0.1 [0.3]; p = 0.04) domains of the QuAL tool. Feedback quality was not associated with the basis of assessment or time taken to provide feedback. CONCLUSION: The quality of the narrative feedback provided to residents during ambulatory patient care was variable with the greatest gap in providing connections between suggestions and evidence about residents' performance. There is a need for ongoing faculty development to improve the quality of narrative feedback provided to residents.

Patient Radiation Doses in IR Procedures: The American College of Radiology Dose Index Registry-Fluoroscopy Pilot.

PURPOSE: To update normative data on fluoroscopy dose indices in the United States for the first time since the Radiation Doses in Interventional Radiology study in the late 1990s. MATERIALS AND METHODS: The Dose Index Registry-Fluoroscopy pilot study collected data from March 2018 through December 2019, with 50 fluoroscopes from 10 sites submitting data. Primary radiation dose indices including fluoroscopy time (FT), cumulative air kerma (Ka,r), and kerma area product (PKA) were collected for interventional radiology fluoroscopically guided interventional (FGI) procedures. Clinical facility procedure names were mapped to the American College of Radiology (ACR) common procedure lexicon. Distribution parameters including the 10th, 25th, 50th, 75th, 95th, and 99th percentiles were computed. RESULTS: Dose indices were collected for 70,377 FGI procedures, with 50,501 ultimately eligible for analysis. Distribution parameters are reported for 100 ACR Common IDs. FT in minutes, Ka,r in mGy, and PKA in Gy-cm2 are reported in this study as (n; median) for select ACR Common IDs: inferior vena cava filter insertion (1,726; FT: 2.9; Ka,r: 55.8; PKA: 14.19); inferior vena cava filter removal (464; FT: 5.7; Ka,r: 178.6; PKA: 34.73); nephrostomy placement (2,037; FT: 4.1; Ka,r: 39.2; PKA: 6.61); percutaneous biliary drainage (952; FT: 12.4; Ka,r: 160.5; PKA: 21.32); gastrostomy placement (1,643; FT: 3.2; Ka,r: 29.1; PKA: 7.29); and transjugular intrahepatic portosystemic shunt placement (327; FT: 34.8; Ka,r: 813.0; PKA: 181.47). CONCLUSIONS: The ACR DIR-Fluoro pilot has provided state-of-the-practice statistics for radiation dose indices from IR FGI procedures. These data can be used to prioritize procedures for radiation optimization, as demonstrated in this work.

Patient Radiation Doses in Interventional Radiology Procedures: Comparison of Fluoroscopy Dose Indices between the American College of Radiology Dose Index Registry-Fluoroscopy Pilot and the Radiation Doses in Interventional Radiology Study.

PURPOSE: To compare radiation dose index distributions for fluoroscopically guided interventions in interventional radiology from the American College of Radiology (ACR) Fluoroscopy Dose Index Registry (DIR-Fluoro) pilot to those from the Radiation Doses in Interventional Radiology (RAD-IR) study. MATERIALS AND METHODS: Individual and grouped ACR Common identification numbers (procedure types) from the DIR-Fluoro pilot were matched to procedure types in the RAD-IR study. Fifteen comparisons were made. Distribution parameters, including the 10th, 25th, 50th, 75th, and 95th percentiles, were compared for fluoroscopy time (FT), cumulative air kerma (Ka,r), and kerma area product (PKA). Two derived indices were computed using median dose indices. The procedure-averaged reference air kerma rate (Ka,r¯) was computed as Ka,r / FT. The procedure-averaged x-ray field size at the reference point (Ar) was computed as PKA / (Ka,r × 1,000). RESULTS: The median FT was equally likely to be higher or lower in the DIR-Fluoro pilot as it was in the RAD-IR study, whereas the maximum FT was almost twice as likely to be higher in the DIR-Fluoro pilot than it was in the RAD-IR study. The median Ka,r was lower in the DIR-Fluoro pilot for all procedures, as was median PKA. The maximum Ka,r and PKA were more often higher in the DIR-Fluoro pilot than in the RAD-IR study. Ka,r¯ followed the same pattern as Ka,r, whereas Ar was often greater in DIR-Fluoro. CONCLUSIONS: The median dose indices have decreased since the RAD-IR study. The typical Ka,r rates are lower, a result of the use of lower default dose rates. However, opportunities for quality improvement exist, including renewed focus on tight collimation of the imaging field of view.

Transitioning to virtual ambulatory care during the COVID-19 pandemic: a qualitative study of faculty and resident physician perspectives.

BACKGROUND: The COVID-19 pandemic resulted in a rapid shift from in-person to virtual care delivery for many medical specialties across Canada. The purpose of this study was to explore the lived experiences of resident physicians and faculty related to teaching, learning and assessment during ambulatory virtual care encounters within the competency-based medical education model. METHODS: In this qualitative phenomenological study, we recruited resident physicians (postgraduate year [PGY] 1-5 trainees) and faculty from the Departments of Surgery and Medicine at Queen's University, Ontario, via purposive sampling. Participants were not required to have exposure to virtual care. Interviews were conducted from September 2020 to March 2021 by 1 researcher, and 2 researchers conducted focus groups via Zoom to explore participants' experiences with the transition to virtual care. These were audio-recorded and transcribed verbatim; qualitative data were analyzed thematically. RESULTS: There were 18 male and 19 female participants; 20 were resident physicians and 17 were faculty; 19 were from the Department of Surgery and 18 from the Department of Medicine. All faculty participants had participated in virtual care during ambulatory care; 2 PGY-1 residents in surgery had not actively participated in virtual care, although they had participated in clinics where faculty were using virtual care. The mean age of faculty participants was 38 (standard deviation [SD] 8.6) years, and the mean age of resident physicians was 29 (SD 5.4) years. Overall, 28 interviews and 4 focus groups (range 2-3 participants per group) were conducted, and 4 themes emerged: teaching and learning, assessment, logistical considerations, and suggestions. Barriers to teaching included the lack of direct observations and teaching time, and barriers to assessment included an absence of specific Entrustable Professional Activities (EPAs) and feedback focused on virtual care-related competencies. Logistical challenges included lack of technological infrastructure, insufficient private office space and administrative burdens. Both resident physicians and faculty did not foresee virtual care limiting resident physicians' ability to progress within competency-based medical education. Benefits of virtual care included increased accessibility to patients for follow-up visits, for disclosing patients' results and for out-of-town visits. Suggestions included faculty development, improved access to technology and space, educational guidelines for conducting virtual care encounters, and development of virtual care-specific competencies and EPAs. INTERPRETATION: In the postgraduate program we studied, virtual care imposed substantial barriers on teaching, learning and assessment during the first year of the COVID-19 pandemic. Adapting to new circumstances such as virtual care with suggestions from resident physicians and faculty may help to ensure the continuity of postgraduate medical education throughout the COVID-19 pandemic.

Chronic opioid use after joint replacement surgery in seniors is associated with increased healthcare utilization and costs: a historical cohort study.

PURPOSE: Postoperative opioid use may be associated with increased healthcare utilization and costs. We sought to examine the relationship between duration of postoperative opioid prescriptions and healthcare costs and resource utilization in senior patients following hip and knee replacement. METHODS: We conducted a historical cohort study evaluating postoperative opioid use and healthcare costs in patients over the age of 65 yr undergoing primary total hip or knee arthroplasty over a ten-year period from 1 April 2006 to 31 March 2016. The last follow-up date was 31 March 2017. We identified preoperative and postoperative opioid prescriptions, patient characteristics, and healthcare costs using deidentified Ontario administrative databases (Institute of Clinical Evaluative Sciences). Duration of postoperative opioid use was divided into four categories: short-term (1-90 days), prolonged (91-180 days), chronic (181-365 days), and undocumented. RESULTS: The study included 49,638 hip and 85,558 knee replacement patients. Although the initial hospitalization accounted for the greatest cost in all patients, over the following year patients in the short-term opioid use group incurred the lowest average costs, and those in the chronic group incurred the highest (hip, CAD 17,528 vs CAD 26,736; knee, CAD 16,043 vs CAD 23,007), driven by increased healthcare resource utilization. CONCLUSION: Chronic opioid use after arthroplasty was associated with higher resource utilization and healthcare costs during the year following surgery. These results can be used to develop predictors of longer opioid use and higher costs. Further research is planned to determine whether recently implemented opioid reduction strategies can reduce healthcare resource utilization.

RéSUMé: OBJECTIF: L'utilisation postopératoire d'opioïdes peut être associée à une augmentation de l'utilisation et des coûts des soins de santé. Nous avons cherché à examiner la relation entre la durée des ordonnances d'opioïdes postopératoires, les coûts des soins de santé et l'utilisation des ressources chez les patients âgés après une arthroplastie de la hanche et du genou. MéTHODE: Nous avons réalisé une étude de cohorte historique évaluant la consommation postopératoire d'opioïdes et les coûts des soins de santé chez les patients de plus de 65 ans subissant une arthroplastie totale primaire de la hanche ou du genou sur une période de dix ans allant du 1er avril 2006 au 31 mars 2016. La dernière date de suivi était le 31 mars 2017. Nous avons identifié les ordonnances pré- et postopératoires d'opioïdes, les caractéristiques des patients et les coûts des soins de santé à l'aide de bases de données administratives de l'Ontario désidentifiées (ICES). La durée de la consommation d'opioïdes postopératoires était divisée en quatre catégories : à court terme (1 à 90 jours), prolongée (91 à 180 jours), chronique (181 à 365 jours) et non documentée. RéSULTATS: L'étude a porté sur 49 638 patients ayant subi une arthroplastie de la hanche et 85 558 patients une arthroplastie du genou. Bien que l'hospitalisation initiale ait représenté le coût le plus élevé chez tous les patients, au cours de l'année suivante, les patients du groupe de consommation d'opioïdes à court terme ont encouru les coûts moyens les plus bas et ceux du groupe chronique les coûts les plus élevés (hanche, 17 528 CAD vs 26 736 CAD; genou, 16 043 CAD vs 23 007 CAD) en raison de l'utilisation accrue des ressources de soins de santé. CONCLUSION: La consommation chronique d'opioïdes après une arthroplastie a été associée à une augmentation de l'utilisation des ressources et des coûts des soins de santé au cours de l'année suivant la chirurgie. Ces résultats peuvent être utilisés pour développer des modèles de prédiction d'une consommation prolongée d'opioïdes et de coûts plus élevés. D'autres recherches sont prévues pour déterminer si les stratégies de réduction de la consommation d'opioïdes récemment mises en œuvre pourront réduire l'utilisation des ressources en soins de santé.

Recognition of intraoperative surgical glove perforation: a comparison by surgical role and level of training.

BACKGROUND: The aim of this study was to characterize the risk of glove perforation among surgical team members performing a typical set of trauma procedures, as well as to identify the rate at which these people recognize potential perforations. METHODS: Gloves used in orthopedic trauma room procedures were collected from all participating team members over 2 weeks and were subsequently examined for perforations. Perforation rates based on glove position, type, wearer and procedure were assessed. RESULTS: Perforations were found in 5.9% of gloves; 4.3% of the perforations were found in outer gloves and 1.6% in inner gloves. Among the outer gloves, 30.7% of the perforations were recognized by the wearer at the time of perforation; none of the inner glove perforations were recognized, even when they were associated with an accompanying outer glove perforation. Significantly more perforations were identified in the gloves of attending staff than in those of other team members. Attending staff experienced more perforations than other wearers, regardless of whether they were acting as the primary surgeon or as an assistant. Perforations were more common in open reduction internal fixation and amputation procedures. For open reduction internal fixation procedures, longer operative times were associated with more frequent glove perforations. CONCLUSION: The rates of glove perforation are high in orthopedic trauma surgeries, and often these perforations are not recognized by the wearer. Attending staff are at an elevated risk of glove perforation. It is recommended that all members of the surgical team change both pairs of gloves whenever an outer glove perforation is observed.

Long-term opioid use in seniors following hip and knee arthroplasty in Ontario: a historical cohort study.

PURPOSE: Canadian seniors who undergo hip and knee arthroplasty often experience significant postoperative pain, which could result in persistent opioid use. We aimed to document the impact of preoperative opioid use and other characteristics on postoperative opioid prescriptions in elderly patients following hip and knee replacement before widespread dissemination of opioid reduction strategies. METHODS: We conducted a historical cohort study to evaluate postoperative opioid use in patients over 65 yr undergoing primary total hip and knee replacement over a ten-year period from 1 April 2006 to 31 March 2016, using linked de-identified Ontario administrative data. We determined the use of preoperative opioids and the duration of postoperative opioid prescriptions (short-term [1-90 days], prolonged [91-180 days], chronic [181-365 days], or undocumented). RESULTS: The study included 49,638 hip and 85,558 knee replacement patients. Eighteen percent of hip and 21% of knee replacement patients received an opioid prescription within 90 days before surgery. Postoperatively, 51% of patients filled opioid prescriptions for 1-90 days, while 24% of hip and 29% of knee replacement patients filled prescriptions between 6 and 12 months, with no impact of preoperative opioid use. Residence in long-term care was a significant predictor of chronic opioid use (hip: odds ratio [OR], 2.64; 95% confidence interval [CI], 1.93 to 3.59; knee: OR, 2.46; 95% CI, 1.75 to 3.45); other risk factors included female sex and increased comorbidities. CONCLUSION: Despite a main goal of joint arthroplasty being relief of pain, seniors commonly remained on postoperative opioids, even if not receiving opioids before surgery. Opioid reduction strategies need to be implemented at the surgical, primary physician, long-term care, and patient levels. These findings form a basis for future investigations following implementation of opioid reduction approaches.

RéSUMé: OBJECTIF: Les aînés canadiens subissant une arthroplastie de la hanche ou du genou éprouvent souvent une douleur postopératoire importante, ce qui pourrait entraîner la consommation persistante d'opioïdes. Nous avons cherché à documenter l'impact d'une utilisation préopératoire d'opioïdes et d'autres caractéristiques sur les prescriptions postopératoires d'opioïdes chez les patients âgés suivant un remplacement de hanche ou de genou avant l'utilisation répandue de stratégies de réduction d'opioïdes. MéTHODE: Nous avons réalisé une étude de cohorte historique pour évaluer la consommation postopératoire d'opioïdes chez les patients de plus de 65 ans subissant une arthroplastie totale primaire de la hanche ou du genou sur une période de dix ans du 1er avril 2006 au 31 mars 2016, à l'aide de données administratives dépersonnalisées et codées de l'Ontario. Nous avons déterminé la durée des ordonnances préopératoires et postopératoires d'opioïdes (à court terme [1-90 jours], prolongées [91-180 jours], chroniques [181-365 jours] ou non documentées). RéSULTATS: L'étude a porté sur 49 638 patients ayant subi une arthroplastie de la hanche et 85 558 patients une arthroplastie du genou. Dix-huit pour cent des patients ayant subi une arthroplastie de la hanche et 21 % des patients ayant subi une arthroplastie du genou ont reçu une ordonnance d'opioïdes dans les 90 jours précédant leur chirurgie. En période postopératoire, 51 % des patients ont utilisé leurs ordonnances d'opioïdes pendant 1 à 90 jours, tandis que 24 % des patients d'arthroplastie de la hanche et 29 % des patients d'arthroplastie du genou ont utilisé leurs ordonnances entre six et 12 mois. Le fait d'habiter dans un établissement de soins de longue durée était un prédicteur important de consommation chronique d'opioïdes (hanche : rapport de cotes [RC], 2,64; intervalle de confiance [IC] à 95 %, 1,93 à 3,59; genou : RC, 2,46; IC 95 %, 1,75 à 3,45); le sexe féminin et l'augmentation des comorbidités constituaient d'autres facteurs de risque. CONCLUSION: Bien que l'un des principaux objectifs de l'arthroplastie articulaire soit le soulagement de la douleur, les personnes âgées continuent généralement à consommer des opioïdes en période postopératoire, même si elles ne prenaient pas d'opioïdes avant leur chirurgie. Il est nécessaire de mettre en œuvre des stratégies de réduction des opioïdes qui s'adressent aux chirurgiens, aux médecins traitants, aux soins de longue durée et aux patients. Ces constatations constituent la base d'études futures réalisées à la suite de la mise en œuvre d'approches de réduction des opioïdes.

Hair of the Dog? Periprosthetic Joint Infection with Streptococcus can is.

A 61-year-old man underwent elective primary total hip arthroplasty at an academic center and presented to the emergency department 2 weeks later with a periprosthetic infection. Intraoperative cultures were positive for Streptococcus canis. He was successfully treated with one-stage revision and 6 weeks of intravenous cefazolin. It was later determined that the patient has a pet dog who frequently licks his legs. We hypothesize that patients with pets are more likely to carry this pathogen as part of their skin microbiome, and further research is required to establish whether S. canis poses an infectious risk beyond that of normal group B Streptococcus skin flora and if preoperative decolonization strategies are warranted.

Delivery Approaches Within Exercise Referral Schemes: A Survey of Current Practice in England.

BACKGROUND: Exercise referral schemes in England offer referred participants an opportunity to take part in an exercise prescription in a nonclinical environment. The aim of these schemes is to effect clinical health benefits, yet there is limited evidence of schemes' effectiveness, which could be due to the heterogeneity in design, implementation, and evaluation. Additionally, there has been no concerted effort to map program characteristics. OBJECTIVE: To understand what key delivery approaches are currently used within exercise referral schemes in England. METHODS: Across England, a total of 30 schemes with a combined total of 85,259 exercise referral scheme participants completed a Consensus on Exercise Reporting Template-guided questionnaire. The questionnaire explored program delivery, nonexercise components, and program management. RESULTS: Results found that program delivery varied, though many schemes were typically 12 weeks in length, offering participants 2 exercise sessions in a fitness gym or studio per week, using a combination of exercises. Adherence was typically measured through attendance, with nonexercise components and program management varying by scheme. CONCLUSION: This research provides a snapshot of current delivery approaches and supports the development of a large-scale mapping exercise to review further schemes across the whole of the United Kingdom in order to provide evidence of best practice and delivery approaches nationwide.

Effectiveness of Structured Physical Activity Interventions Through the Evaluation of Physical Activity Levels, Adoption, Retention, Maintenance, and Adherence Rates: A Systematic Review and Meta-Analysis.

BACKGROUND: Structured physical activity (PA) interventions (ie, intentionally planned) can be implemented in a variety of facilities, and therefore can reach a large proportion of the population. The aim of the authors was to summarize the effectiveness of structured interventions upon PA outcomes, in addition to proportions of individuals adopting and maintaining PA, and adherence and retention rates. METHODS: Systematic review with narrative synthesis and exploratory meta-analyses. Twelve studies were included. RESULTS: Effectiveness on PA levels during adoption (pre- to first time point) showed a trivial standardized effect (0.15 [-0.06 to 0.36]); during maintenance (any time point after the first and >6 mo since initiation) the standardized effect was also trivial with a wide interval estimate (0.19 [-0.68 to 1.07]). Few studies reported adoption (k = 3) or maintenance rates (k = 2). Retention at follow-up did not differ between structured PA or controls (75.1% [65.0%-83.0%] vs 75.4% [67.0%-82.3%]), nor did intervention adherence (63.0% [55.6%-69.6%] vs 77.8% [19.4%-98.1%]). CONCLUSION: Structured PA interventions lack evidence for effectiveness in improving PA levels. Furthermore, though retention is often reported and is similar between interventions and controls, adoption, maintenance, and adherence rates were rarely reported rendering difficulty in interpreting results of effectiveness of structured PA interventions.

Resident perceptions of Competency-Based Medical Education.

BACKGROUND: Residency training programs in Canada are undergoing a mandated transition to competency-based medical education (CBME). There is limited literature regarding resident perspectives on CBME. As upper year residents act as mentors and assessors for incoming cohorts, and are themselves key stakeholders in this educational transition, it is important to understand how they view CBME. We examined how residents who are not currently enrolled in a competency-based program view that method of training, and what they perceive as potential advantages, disadvantages, and considerations regarding its implementation. METHODS: Sixteen residents volunteered to participate in individual semi-structured interviews, with questions focussing on participants' knowledge of CBME and its implementation. We used a grounded theory approach to develop explanations of how residents perceive CBME. RESULTS: Residents anticipated improved assessment and feedback, earlier identification of residents experiencing difficulties in training, and greater flexibility to pursue self-identified educational needs. Disadvantages included logistical issues surrounding CBME implementation, ability of attending physicians to deliver CBME-appropriate feedback, and the possibility of assessment fatigue. Clear, detailed communication and channels for resident feedback were key considerations regarding implementation. CONCLUSIONS: Resident views align with educational experts regarding the practical challenges of implementation. Expectations of improved assessment and feedback highlight the need for both residents and attending physicians to be equipped in these domains. Consequently, faculty development and clear communication will be crucial aspects of successful transitioning to CBME.

CONTEXTE: Les programmes de résidence canadiens effectuent un passage obligatoire vers la formation médicale fondée sur les compétences (FMFC). Peu de littérature documente les perspectives des résidents sur la FMFC. Comme les résidents senior agissent comme mentors et évaluateurs pour les résidents qui débutent, et qu'ils sont eux-mêmes des participants clés dans cette transition éducative, il est important de comprendre comment ils perçoivent la FMFC. Nous avons examiné comment les résidents qui ne sont pas actuellement inscrits dans un programme fondé sur les compétences perçoivent cette méthode de formation et ce qu'ils perçoivent comme avantages et désavantages potentiels, ainsi que leurs réflexions concernant sa mise en œuvre. MÉTHODES: Seize résidents se sont portés volontaires pour participer à des entrevues individuelles semi-structurées, avec des questions ciblant les connaissances des participants relativement à la FMFC et à sa mise en œuvre. Nous avons eu recours à l'approche de la théorisation ancrée pour élaborer des explications sur la manière dont les résidents perçoivent la FMFC. RÉSULTATS: Les résidents s'attendaient à une amélioration de l'évaluation et de la rétroaction, à un repérage plus précoce des résidents éprouvant des difficultés dans leur formation, ainsi qu'à une plus grande souplesse pour ajuster la formation selon les besoins d'apprentissages auto-identifiés par les résidents. Les désavantages comprenaient des problèmes logistiques entourant la mise en œuvre de la FMFC, la capacité des médecins traitants à fournir une rétroaction appropriée axée sur les compétences, ainsi que la possibilité d'une lassitude à l'égard des évaluations. Une communication claire et détaillée ainsi que des canaux pour la rétroaction aux résidents étaient des considérations clés à propos de la mise en œuvre. CONCLUSIONS: Les opinions des résidents concordent avec celles des experts en éducation au sujet des défis pratiques de la mise en œuvre. Les attentes en ce qui a trait à une amélioration de l'évaluation et de la rétroaction soulignent le besoin, autant pour les résidents que pour les médecins traitants, d'être bien préparés dans ces domaines. Par conséquent, la formation professorale et une communication claire représenteront des aspects essentiels d'une transition réussie à la FMFC.
