What is Transferred and How Much is Retained? A Simulation Study of Complex Surgical Skills.

INTRODUCTION: Studies indicate that learning surgical skills on low-fidelity models is equally beneficial to learning on high-fidelity models in terms of skills retention and transfer. However, it is unclear how low-fidelity simulation training impacts retention and transfer in novice learners, particularly on complex surgical tasks that incorporate multiple challenging skills. This study explores the capacity of complete novices to learn and transfer complex surgical skills from a low-fidelity model to a high-fidelity simulation after a delay. METHODS: Task-naïve medical and nonmedical undergraduate students (n = 62) participated in a three-phase prospective double-arm randomized (2:1) experimental study. Participants completed two skills training sessions (end-to-side anastomosis) on a low-fidelity bench model. After a 4-week delay, participants completed the task again either using the low-fidelity model or a high-fidelity model (cadaver) and were assessed using a validated checklist. RESULTS: There was a significant time × fidelity group interaction (P = 0.004). Simple effects analysis indicated the high-fidelity group (Mdiff = 4.18, P < 0.001) performed significantly worse (P = 0.003) in phase 3 relative to phase 2 compared to the low-fidelity group (Mdiff = 0.75, P = 0.39). Post hoc logistic regression analysis indicated that radial suturing technique and economy of motion skills were less likely to be completed correctly for those in the high-fidelity group. CONCLUSIONS: These findings suggest that for novice populations, relying on low-fidelity simulation training as a source of teaching complex skills may not provide a reliable transfer to high-fidelity models and in turn clinical settings.

Assessing geographic and industry-related trends in bladder cancer in Ontario: A population-based study.

INTRODUCTION: Bladder cancer (BC) is the fifth most prevalent cancer in Canada, with 9000 Canadians diagnosed each year. While smoking is the most important risk factor, environmental and occupational carcinogens have been found to significantly contribute to BC rates. As Canada is highly reliant on natural resource industries, this study seeks to identify geographical and industry-related trends of BC rates in Ontario. METHODS: The 1991 and 2001 Canadian Census Health and Environment Cohort (CanCHEC; Statistics Canada) was used, along with individual years of census data. Maps identifying hot and cold spots for BC within Ontario were generated, and the former were assessed for industry patterns between location and BC rates. Cox proportional hazards models were run for each age cohort to predict the likelihood of developing BC by industry of work. RESULTS: Significant geographical and industrial trends in BC rates were identified. For 1991-2001, hot spots included the Cochrane, Manitoulin, Parry Sound, and Sudbury (90% confidence interval [CI]), and Nipissing and Temiskaming (95% CI) regions. Toronto and York were cold spots. Concurrently, metal (p=0.039), paper and publishing (p=0.0062), and wood and furniture (p<0.0001) industries had increased rates of BC. Notably, these industries had high employment density in our hot spot areas and low density in our cold spots. CONCLUSIONS: Significant geographical and industrial BC trends were found in Northern Ontario regions reliant on heavy employment in natural resource-based industries, such as forestry, agriculture, and wood/paper. These findings may inform future screening guidelines and aid in identifying individuals at risk of BC development.

Burnout in Canadian urology: Cohort analysis from the 2018 Canadian Urological Association census.

INTRODUCTION: Physician burnout is associated with medical error, patient dissatisfaction, and poorer physician health. Urologists have reported high levels of burnout and poor work-life integration compared with other physicians. Burnout rates among Canadian urologists has not been previously investigated. We aimed to establish the prevalence of Canadian urologist burnout and associated factors. METHODS: In the 2018 Canadian Urological Association census, the Maslach Burnout Inventory questions were assigned to all respondents. Responses from 105 practicing urologists were weighted by region and age group to represent 609 urologists in Canada. Burnout was defined as scoring high on the scales of emotional exhaustion or depersonalization. Demographic and practice variables were assessed to establish factors associated with burnout. Comparisons were made to the results of the 2016 American Urological Association census. RESULTS: Overall, 31.8% of respondents met the criteria for burnout. There was no effect of subspecialty practice or practice setting on burnout. On univariate analysis, rates of burnout were highest among urologists under financial strain (50.8%), female urologists (45.3%), and early-to-mid-career urologists (37.7-41.8%). Factors associated with demanding practices and poor work-life integration were predictive of burnout. A total of 12.2% of urologists reported seeking burnout resources and 54.0% wished there were better resources available. CONCLUSIONS: Urologist burnout in Canada is lower than reported in other countries, but contributing factors are similar. Urologists who report demanding clinical practices (particularly in early-to-mid career), poor work-life integration, financial strain, and female gender may benefit from directed intervention for prevention and management of burnout. Burnout resources for Canadian urologists require further development.

Point-of-care ultrasonography for the diagnosis of testicular torsion: a practical resident curriculum.

Background: Prompt Doppler ultrasonography to aid in diagnosis is often key to managing testicular torsion, but there may be delays in access; a faster, more widely available alternative is point-of-care ultrasonography (POCUS). The purpose of this study was to develop and evaluate a scrotal POCUS curriculum for urology and emergency medicine residents. Methods: Content experts in urology, emergency medicine and diagnostic imaging collaborated in a modified Delphi method to design a practical didactic curriculum for scrotal POCUS for the identification of testicular torsion. Training included 3 online video teaching modules and a 1-hour hands-on teaching session with standardized adult patients. We evaluated participants' competency in scrotal POCUS using a validated scale. We assessed participants' knowledge, comfort and confidence in performing scrotal POCUS before and after the intervention and at 3 months. Results: Twenty-four urology (n = 12) and emergency medicine (n = 12) residents participated in the curriculum. After hands-on practice, 23 participants (96%) were deemed competent at scrotal POCUS. Pre-post testing showed significant improvement in knowledge (mean score 63% v. 80%, p < 0.001), comfort (mean Likert score 0.6 v. 3.6, p < 0.001) and confidence (mean Likert score 1.0 v. 2.1, p < 0.001) after the intervention. These effects were maintained at the 3-month assessment. Conclusion: The scrotal POCUS curriculum was effective and acceptable to both urology and emergency medicine residents. The findings suggest that scrotal POCUS can be learned effectively through a short hands-on session and didactic instruction.

Contexte: Le diagnostic rapide d'une torsion testiculaire à l'aide d'une échographie Doppler est souvent crucial à la prise en charge de ce trouble. Or, comme l'accès à cet examen peut être limité, l'échographie portable constitue une solution de rechange rapide et largement accessible. La présente étude visait la mise au point et l'évaluation d'un programme de formation sur l'échographie portable scrotale destiné aux résidents en urologie et en médecine d'urgence. Méthodes: Des experts en urologie, en médecine d'urgence et en imagerie diagnostique se sont servis d'une méthode Delphi modifiée pour concevoir un programme de formation sur l'échographie portable visant à faciliter le diagnostic de la torsion testiculaire. Ce programme comprenait 3 modules d'apprentissage vidéo en ligne, ainsi qu'une séance pratique d'une heure auprès de patients adultes normalisés. Nous avons évalué les compétences des participants en matière d'échographie portable scrotale au moyen d'une échelle validée. Nous avons également évalué les connaissances, l'aisance et le niveau de confiance des participants à l'égard de cet examen avant et immédiatement après la formation, puis 3 mois plus tard. Résultats: Au total, 24 résidents en urologie (n = 12) et en médecine d'urgence (n = 12) ont suivi le programme de formation. Après la séance pratique, 23 participants (96 %) avaient les compétences nécessaires à la réalisation d'une échographie portable scrotale. La comparaison des résultats obtenus avant et immédiatement après la formation a montré une augmentation significative des connaissances (note moyenne : 63 % c. 80 %; p < 0,001), de l'aisance (moyenne à l'échelle de Likert : 0,6 c. 3,6; p < 0,001) et du niveau de confiance (moyenne à l'échelle de Likert : 1,0 c. 2,1; p < 0,001) des participants. Les effets de la formation étaient toujours présents 3 mois plus tard. Conclusion: Le programme de formation sur l'échographie portable scrotale s'est avéré efficace et acceptable pour les résidents en urologie et en médecine d'urgence. Les résultats obtenus laissent croire qu'une formation pédagogique et une courte séance d'apprentissage pratique permettent l'enseignement efficace de l'échographie portable scrotale.

Assessing gender trends in Canadian urology.

INTRODUCTION: The number of female medical students and physicians entering the workforce is increasing. Despite this trend, some surgical specialties are still considered male-dominant. Urology has a significant male predominance in both residency and independent practice. This male predominance could have an impact on the physician work force, mentorship opportunities for females pursuing surgery, and on medical student attraction to urology as a specialty. Research conducted in the U.S. has shown that although fewer females enter the field of urology, acceptance rates between the two genders are similar. This study aims to identify if a trend towards gender-specific acceptance into urology residency exists within Canada. We also seek to identify if gender trends in acceptance to urology differ from other surgical specialties in Canada and assess the current workforce trends in Canadian urological practice. METHODS: Canadian Residency Matching Services (CARMS) data from the previous 10 years was analyzed. This data was accessed from the CARMS website.1 Logistic regression analyses were used to assess if any significant difference exists between the rates of female and male applicant acceptance into urology. These rates were then compared to the rates of female and male acceptance into surgical residency as a whole and to specific surgical specialties, such as general surgery, orthopedics, and otolaryngology. RESULTS: Within urology applicants, there is no evidence that the success rate over time between males and females differs (p=0.47). Within surgical residency applicants, there is no evidence that the success rate over time differs between male and female applicants (p=0.84). In comparing these two rates, there is also no significant difference between rates of acceptance to urology vs. surgery in general for female applicants (p=0.45). General surgery has a higher growth of females entering into the specialty compared to urology (p=0.026). Conversely, otolaryngology (p=0.123) and orthopedics (p=0.163) did not show a significant difference in the rates of female acceptance as compared to males over time. Our small sample size of 451 applicants over the 10-year time span (122 female, 329 male) could represent a limitation, however, we did ensure to analyze a 10-year sample to attempt to get an accurate representation of any trends. CONCLUSIONS: Our data identifies that there is no significant trend toward male acceptance into urology over female applicants. There is no significant difference related to female acceptance specifically into urology or any difference between rates of females accepted into urology as compared to all other surgical subspecialties combined.
