Disparities in Pediatric Operative Experience during Urology Residency Training

Can paediatric surgical registrars safely perform supervised hypospadias surgery?

INTRODUCTION

Hypospadias repair is regarded as a technically demanding, complex procedure, with variable outcomes. Therefore, it tends to be performed by consultants, with limited trainee involvement. We aimed to study the clinical outcomes of supervised registrars performing proximal and distal hypospadias repairs, compared to their consultant mentors.

METHODS

We undertook a retrospective review of all primary hypospadias repairs performed between April 2013-April 2022 at our tertiary paediatric urology centre. Redo repairs and patients lost to follow-up were excluded. Pre-operative anatomy, theatre time, grade of primary surgeon (registrar (trainees and non-training middle grades) or consultant), operative technique, follow-up duration, complications, and reoperation rates were recorded. The procedures were assessed in two groups according to the primary operator: registrar or consultant. The Zwisch scale is used to describe level of consultant support. Registrars as primary operators received "passive help" or "supervision" (Zwisch levels 3/4). Consultants as primary operators provided registrars with "show-and-tell" or "active help" (Zwisch levels 1/2).

RESULTS

270 procedures performed on 228 patients met the inclusion criteria. 109 were performed by registrars and 161 by consultants. In both groups, median age was two years (p = 0.23). Median theatre time was similar (registrars 2.8 h vs. consultants 2.7 h, p = 0.88), as was median follow-up (registrars 25months, vs. consultants 21months, p = 0.99). Operations performed by registrars were 76% distal and 24% proximal; and by consultants were 62% distal and 38% proximal. The overall urethroplasty complication rate was similar, at 24% for registrars and 23% for consultants (p = 0.89). The summary table shows the distribution of different complications. Re-operation rate was 16% in both groups (p = 0.99). Complications were further assessed according to operation type (TIP vs. two-stage repair).

DISCUSSION

Contrary to popular belief amongst hypospadiologists, we found complication rates were similar for registrar and consultant surgeons. We question that involvement of registrars increases complications. The literature demonstrates safety of trainee performance of limited steps of the procedure. However our institution permits registrars to perform up to the whole hypospadias repair under direct supervision, with no predefined limit to their involvement.

CONCLUSION

Paediatric surgical registrars can be safely supervised to have substantial involvement in proximal and distal hypospadias repair, without compromising the duration or outcomes of surgery. We hope that allowing more registrar involvement can lead to faster acquisition of surgical skills, whilst remaining under the safety of senior supervision. Increasing opportunities for those with an aptitude for hypospadias repair can equip them with skills and confidence for entering fellowship training.

Longitudinal Changes in the Operative Experience for Junior Urology Residents

OBJECTIVE

To evaluate longitudinal trends in surgical case volume among junior urology residents. There is growing perception that urology residents are not prepared for independent practice, which may be linked to decreased exposure to major cases early in residency.

METHODS

Retrospective review of deidentified case logs from urology residency graduates from 12 academic medical centers in the United States from 2010 to 2017. The primary outcome was the change in major case volume for first-year urology (URO1) residents (after surgery internship), measured using negative binomial regression.

RESULTS

A total of 391,399 total cases were logged by 244 residency graduates. Residents performed a median of 509 major cases, 487 minor cases, and 503 endoscopic cases. From 2010 to 2017, the median number of major cases performed by URO1 residents decreased from 64 to 49 (annual incidence rate ratio 0.90, P < .001). This trend was limited to oncology cases, with no change in reconstructive or pediatric cases. The number of major cases decreased more for URO1 residents than for residents at other levels (P-values for interaction <.05). The median number of endoscopic cases performed by URO1 residents increased from 85 to 194 (annual incidence rate ratio 1.09, P < .001), which was also disproportionate to other levels of residency (P-values for interaction <.05).

CONCLUSION

There has been a shift in case distribution among URO1 residents, with progressively less exposure to major cases and an increased focus on endoscopic surgery. Further investigation is needed to determine if this trend has implications on the surgical proficiency of residency graduates.

Effect of COVID-19 on Graduating Urology Resident Case Logs: Analysis of the Accreditation Council of Graduate Medical Education National Data Reports

OBJECTIVE

To assess the national case logs of the first graduating urologic resident cohorts to have trained during the COVID-19 pandemic for effects on surgical volumes.

METHODS

The nationally aggregated Accreditation Council for Graduate Medical Education urology resident case logs were obtained for graduates of academic years (AYs) 2015-2016 through 2020-2021. Case volume differences for tracked index categories were compared between AYs with a 1-way analysis of variance. Data were then combined into pre-COVID and COVID-affected resident cohorts and differences in average cases logged were analyzed with 2-tailed student's t-tests.

RESULTS

Graduating urology residents logged an average of 1322 (SD 24.8) cases over their residency during the examined period. Total cases had multiple statistical differences between AYs but the only index category with a statistically significant decrease for a COVID-affected AY compared to pre-COVID AY was pediatric majors: AY 2020-2021 logged fewer cases than AY 2015-2016 (53.9 vs 63.0, P = .004) and AY 2018-2019 (53.9 vs 61.2, P = .04). When aggregated into pre- and COVID-affected cohorts, both pediatric minor (123.4 vs 117.5, P = .049) and pediatric major (61.4 vs 56.8, P = .003) case averages decreased for the COVID-affected cohort of residents, but no adult index category decreased.

CONCLUSION

National graduating urology resident surgical volume for adult index categories was maintained through the pandemic. Pediatric cases saw a statistical decrease in volume of questionable clinical significance. This does not eliminate concern that individuals may have experienced a detrimental impact on their resident education.

ACGME Operative Case Log Accuracy Varies Among Surgical Programs

OBJECTIVE

This study evaluates the accuracy of reported the Accreditation Council for Graduate Medical Education (ACGME) operative case logs from graduated residents compared to institutional operating room electronic records (ORER). We hope this will help guide review committees and institutions develop complete, accurate resident case logs.

DESIGN

This is a retrospective, cross-sectional study of general surgery (GS), neurosurgery (NS), and orthopedic surgery (OS) resident physicians. ACGME and ORER cases from 2009 to 2010 were analyzed and each case and current procedural terminology (CPT) code directly compared (ORER vs. ACGME).

SETTING

Single academic tertiary-care medical center (University of Kentucky, Lexington, KY).

PARTICIPANTS

Eleven thousand nine hundred and twenty-three cases for 46 residents among the 3 residency programs were analyzed.

RESULTS

There was an overall logging accuracy of 72% for ORER cases reflected in the ACGME case logs. OS residents had a higher rate of logging accuracy (OS 91%, GS 69%, NS 58%, chi-square p = 0.014) and mean annual number of cases compared to the other 2 programs (OS 452, GS 183, NS 237, ANOVA p = 0.001). NS residents had higher accuracy of CPT codes than post-graduate years 2 to 5 in other programs (p < 0.017). There was a strong positive correlation between the number of cases completed per resident and case logging accuracy, (rho = 0.769, p < 0.001) consistent for NS and GS, but not OS.

CONCLUSIONS

This study shows only 72% of a residents' operative experience is captured in the ACGME case log across 3 surgical programs. There is significant variability among surgical programs and among post-graduate year cohorts regarding case log and CPT code accuracy. There is a strong correlation with the total number of cases performed and increasing case log accuracy. Low case log accuracy may reflect individual resident behavior instead of program operative exposure. Further studies are needed to determine if ORER may serve as a more complete assessment of the operative experience of a resident and program.

Inter-Resident Variability in Urologic Operative Case Volumes Over Time: A Review of the ACGME Case Logs From 2009 to 2016

OBJECTIVES

To assess the effect of the changing landscape of urologic residency education and training on resident operative exposure and inter-resident variability.

METHODS

The Accreditation Council for Graduate Medical Education (ACGME) case logs for graduating urology chief residents were reviewed from Academic Year (AY) 2009-2010 to 2016-2017. Cases were stratified into the 4 ACGME categories - general urology, endourology, oncology, and reconstruction. Linear regression models analyzed the association between training year, volume, and type of cases performed. Inter-resident variability in case exposure was calculated by the difference between the ACGME reported 10th and 90th percentiles.

RESULTS

During the study period, the mean number of cases performed per resident was 1092 (standard deviation 32.7). Although there was no significant change in total case volume, there were changes within case categories. Endoscopic, retroperitoneal oncology, and male reconstruction case volume all increased significantly (Δ20.1%, Δ 5.1%, Δ 8.2%, respectively, all P < .05). This was balanced with a concomitant decrease in pelvic oncology and female reconstruction cases (Δ 10.0% and Δ 14.5%, respectively, both P < .05). There was a 27.8% increase in laparoscopic/robotic cases (P < .001). The ratio difference between the 10th percentile and 90th percentile ranged from a low of 2.5 for retroperitoneal oncology cases to a high of 5.2 for extracorporeal shock wave lithotripsy and percutaneous nephrolithotomy.

CONCLUSION

From AY2009-2010 to 2016-2017, residency case volume has remained constant, but there has been a change in types of cases performed and proliferation of minimally invasive techniques. Significant variability of inter-resident operative experience was noted.
