Impact of Resident Involvement in Neurosurgery: An American College of Surgeons' National Surgical Quality Improvement Program Database Analysis of 33,977 Patients. Neurospine 2018; 15:54-65. [PMID: 29656619 PMCID: PMC5944634 DOI: 10.14245/ns.1836008.004] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2018] [Revised: 03/16/2018] [Accepted: 03/20/2018] [Indexed: 12/21/2022] Open
Abstract
OBJECTIVE There is conflicting and limited literature on the effect of intraoperative resident involvement on surgical outcomes. Our study assessed effects of resident involvement on outcomes in patients undergoing neurosurgery. METHODS We identified 33,977 adult neurosurgical cases from 374 hospitals in the 2006-2012 National Surgical Quality Improvement Program, a prospectively collected national database with established reproducibility and validity. Outcomes were compared according to resident involvement before and after 1:1 matching on procedure and perioperative risk factors. RESULTS Resident involvement was documented in 13,654 cases. We matched 10,170 resident-involved cases with 10,170 attending-alone. In the matched sample, resident involvement was associated with increased surgery duration (average, 34 minutes) and slight increases in odds for prolonged hospital stay (odds ratio, 1.2; 95% confidence interval [CI], 1.2-1.3) and complications (odds ratio, 1.2; 95% CI, 1.1-1.3) including infections (odds ratio, 1.4; 95% CI, 1.2-1.7). Increased risk for infections persisted after controlling for surgery duration (odds ratio, 1.3; 95% CI, 1.1-1.5). The majority of cases were spine surgeries, and resident involvement was not associated with morbidity or mortality for malignant tumor and aneurysm patients. Training level of residents was not associated with differences in outcomes. CONCLUSION Resident involvement was more common in sicker patients undergoing complex procedures, consistent with academic centers undertaking more complex cases. After controlling for patient and intraoperative characteristics, resident involvement in neurosurgical cases continued to be associated with longer surgical duration and slightly higher infection rates. Longer surgery duration did not account for differences in infection rates.

Abstract
Aim. To evaluate the feasibility of implanting 3D-printed brain aneurysm model in human cadavers and to assess their utility in neurosurgical research, complex case management/planning, and operative training. Methods. Two 3D-printed aneurysm models, basilar apex and middle cerebral artery, were generated and implanted in four cadaveric specimens. The aneurysms were implanted at the same anatomical region as the modeled patient. Pterional and orbitozygomatic approaches were done on each specimen. The aneurysm implant, manipulation capabilities, and surgical clipping were evaluated. Results. The 3D aneurysm models were successfully implanted to the cadaveric specimens' arterial circulation in all cases. The features of the neck in terms of flexibility and its relationship with other arterial branches allowed for the practice of surgical maneuvering characteristic to aneurysm clipping. Furthermore, the relationship of the aneurysm dome with the surrounding structures allowed for better understanding of the aneurysmal local mass effect. Noticeably, all of these observations were done in a realistic environment provided by our customized embalming model for neurosurgical simulation. Conclusion. 3D aneurysms models implanted in cadaveric specimens may represent an untapped training method for replicating clip technique; for practicing certain approaches to aneurysms specific to a particular patient; and for improving neurosurgical research.

Abstract
OBJECT
The authors sought to determine the impact of resident participation on overall 30-day morbidity and mortality following neurosurgical procedures.
METHODS
The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who had undergone neurosurgical procedures between 2006 and 2012. The operating surgeon(s), whether an attending only or attending plus resident, was assessed for his or her influence on morbidity and mortality. Multivariate logistic regression, was used to estimate odds ratios for 30-day postoperative morbidity and mortality outcomes for the attending-only compared with the attending plus resident cohorts (attending group and attending+resident group, respectively).
RESULTS
The study population consisted of 16,098 patients who had undergone elective or emergent neurosurgical procedures. The mean patient age was 56.8 ± 15.0 years, and 49.8% of patients were women. Overall, 15.8% of all patients had at least one postoperative complication. The attending+resident group demonstrated a complication rate of 20.12%, while patients with an attending-only surgeon had a statistically significantly lower complication rate at 11.70% (p < 0.001). In the total population, 263 patients (1.63%) died within 30 days of surgery. Stratified by operating surgeon status, 162 patients (2.07%) in the attending+resident group died versus 101 (1.22%) in the attending group, which was statistically significant (p < 0.001). Regression analyses compared patients who had resident participation to those with only attending surgeons, the referent group. Following adjustment for preoperative patient characteristics and comorbidities, multivariate regression analysis demonstrated that patients with resident participation in their surgery had the same odds of 30-day morbidity (OR = 1.05, 95% CI 0.94–1.17) and mortality (OR = 0.92, 95% CI 0.66–1.28) as their attendingonly counterparts.
CONCLUSIONS
Cases with resident participation had higher rates of mortality and morbidity; however, these cases also involved patients with more comorbidities initially. On multivariate analysis, resident participation was not an independent risk factor for postoperative 30-day morbidity or mortality following elective or emergent neurosurgical procedures.

Abstract
OBJECT This study evaluates the impact of resident presence in the operating room on postoperative outcomes in neurosurgery. METHODS The authors retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and identified all cases treated in a neurosurgery service in 2011. Propensity scoring analysis and multiple logistic regression models were used to reduce patient bias and to assess independent effect of resident involvement. RESULTS Of the 8748 neurosurgery cases identified, residents were present in 4529 cases. Residents were more likely to be involved in complex procedures with longer operative duration. The multivariate analysis found that resident involvement was not a statistically significant factor for overall complications (OR 1.116, 95% CI 0.961-1.297), surgical complications (OR 1.132, 95% CI 0.825-1.554), medical complications (OR 1.146, 95% CI 0.979-1.343), reoperation (OR 1.250, 95% CI 0.984-1.589), mortality (OR 1.164, 95% CI 0.780-1.737), or unplanned readmission (OR 1.148, 95% CI 0.946-1.393). CONCLUSIONS In this multicenter study, the authors demonstrated that resident involvement in the operating room was not a significant factor for postoperative complications in neurosurgery service. This analysis also showed that much of the observed difference in postoperative complication rates was attributable to other confounding factors. This is a quality indicator for resident trainees and current medical education. Maintaining high standards in postgraduate training is imperative in enhancing patient care and reducing postoperative complications.

Abstract
Microscope-integrated near-infrared indocyanine green videoangiography (ICGVA) has been shown to be a useful adjunct for intracranial aneurysm surgery. That the routine application of this technique reduces the risk of postoperative ischaemic complication, however, has not been reported. We present a retrospective matched-pair comparison of ICGVA guided aneurysm surgery versus historic control surgical cohort treated by the same author. Index patients and controls were matched for aneurysm size, location, patient demographics, risk factors, comorbidities, and surgical treatments. Ninety-one eligible patients with 100 intracranial aneurysms were treated using ICGVA assistance. There were no statistically significant differences between the two groups in terms of patient age, sex, risk factors, comorbidities and aneurysm characteristics. Of the 100 aneurysms in the ICGVA group, 107 investigations of ICGVA were performed. In 79 aneurysms (79.0%), ICGVA was considered useful but did not affect surgical management. In six patients (6.0%), ICGVA led to a crucial change of intraoperative strategies. In nine patients (9.0%), it was considered critical in assuring patency of small perforators. ICGVA was of no benefit in four patients (4.0%) and was misleading in two (2.0%). Postoperative ischaemic complications occurred in three patients (3.3%) in the ICGVA group compared with seven patients (7.7%) in the control group (p<0.001). Our study supports the use of ICGVA in aneurysm surgery as a safe and effective modality of intraoperative blood flow assessment. With all limitations of a retrospective matched-pair comparison, the use of ICGVA during routine aneurysm surgery reduces the incidence of postoperative ischaemic complications.

Abstract
BACKGROUND Complex, oncologic surgery is an important component of resident education. Our objective was to evaluate the impact of resident participation in oncologic procedures on overall 30-day morbidity and mortality. METHODS A retrospective cohort analysis was performed using the National Surgical Quality Improvement Program Participant User Files for 2005-2009. Colorectal, hepatopancreaticobiliary, and gastroesophageal oncology procedures were included. Multivariate logistic regression was used to assess the impact of trainee involvement on 30-day morbidity and mortality after adjusting for potential confounders. RESULTS A total of 77,862 patients were included for analysis, 53,885 (69.2%) involving surgical trainees and 23,977 (30.8%) without trainees. The overall 30-day morbidity was significantly higher in the trainee group [27.2 vs. 21%, adjusted odds ratio (AOR) 1.19, 95% confidence interval (CI) 1.15-1.24, p < 0.0001)]; however, there was significantly lower 30-day postoperative mortality in the trainee group (1.9 vs. 2.1%, AOR 0.87, 95% CI 0.77-0.98, p = 0.02) and significantly lower failure-to-rescue rate (defined as mortality rate among patients suffering one or more postoperative complications) (5.9 vs. 7.6%, AOR 0.79, 95% CI 0.68-0.90, p = 0.001). The overall 30-day morbidity was highest in the PGY 5 level (29%) compared to 24% for PGY 1 or 2 and 23% for PGY 3 (AOR per level increase 1.05, 95% CI 1.03-1.07, p < 0.0001). CONCLUSIONS Trainee participation in complex, oncologic surgery is associated with significantly higher rates of 30-day postoperative complications in NSQIP-participating hospitals; however, this effect is countered by overall lower 30-day mortality and improved rescue rate in preventing death among patients suffering complications.

Abstract
INTRODUCTION AND HYPOTHESIS To investigate the outcome of the surgical educational course setting in patients undergoing urinary incontinence (UI)/pelvic organ prolapse (POP) repair. METHODS A case-control study of patients who underwent surgery for UI and/or POP during educational post-graduate courses (group A) or during routine hospital work (control--group B). The primary outcome measures were changes in the incontinence rate, presence/absence of POP, and complications. For 2 x 2 tables, chi (2) test was used. Multivariate logistic regression models were developed. RESULTS One hundred eighty-six patients belonged to group A and 158 to group B; median follow-up was 46.7 months. Failure, complication, and re-operation rates for UI repair were not significantly different in the two groups: p = 0.162, p = 0.110, p = 0.188, respectively. The logistic regression analysis for POP repair showed that group A has higher risk for failure (OR = 2.71; 95% CI: 1.31-5.61) and higher complication rate (OR = 2.38; 95% CI: 1.31-4.32). CONCLUSION Patients who underwent surgery during educational course developed a poorer outcome after POP repair and higher complication rate.

Abstract
OBJECTIVE With improvements in endovascular techniques, fewer aneurysms are treated by surgical clipping, and those aneurysms targeted for open surgery are often complex and difficult to treat. We devised a hollow, 3-dimensional (3D) model of individual cerebral aneurysms for preoperative simulation and surgical training. The methods and initial experience with this model system are presented. METHODS The 3D hollow aneurysm models of 3 retrospective and 8 prospective cases were made with a prototyping technique according to data from 3D computed tomographic angiograms of each patient. Commercially available titanium clips used in our routine surgery were applied, and the internal lumen was observed with an endoscope to confirm the patency of parent vessels. The actual surgery was performed later. RESULTS In the 8 prospective cases, the clips were applied during surgery in the same direction and configuration as in the preoperative simulation. Fine adjustments were necessary in each case, and 2 patients needed additional clips to occlude the atherosclerotic aneurysmal wall. With these 3D models, it was easy for neurosurgical trainees to grasp the vascular configuration and the concept of neck occlusion. Practicing surgery with these models also improved their handling of the instruments used during aneurysm surgery, such as clips and appliers. CONCLUSION Using the hollow 3D models to simulate clipping preoperatively, we could treat the aneurysms confidently during live surgery. These models allow easy and concrete recognition of the 3D configuration of aneurysms and parent vessels.

Abstract
PURPOSE Robot-assisted laparoscopic prostatectomy (RALP) is an increasingly popular treatment choice among men with clinically localized prostate cancer and has resulted in the need to adequately train urologists to perform the procedure. We reviewed the City of Hope experience to determine if the extent of fellow involvement in the procedure has an adverse effect on surgical outcomes. PATIENTS AND METHODS We reviewed the charts of 1833 patients who underwent RALP at the City of Hope from January 2004 to September 2007. During the academic year, each fellow has participated in 300 or more RALP with a systematic stepwise approach to learning the operation. The procedure is divided into six segments arranged by the sequence of learning. We examined intraoperative and perioperative outcomes stratified by quartiles of the academic year corresponding to the fellows' progress through the different segments of the operation. RESULTS No differences were found across quartiles of the academic year for intraoperative or perioperative complications, length of hospital stay, continence rates at 1 year, time to continence, and prostate-specific antigen-free recurrence rates. In the 1st and 3rd quarters of the academic year, from July to September and January to March, there were slightly longer operative times with a mean of 2.9 hours compared with the 2nd and 4th quarter mean of 2.8 hours (P = 0.01). The 3rd quarter also demonstrated slightly higher estimated blood loss of 280 mL compared with the overall mean of 262 mL (P = 0.02). During the 3rd quarter of the year, the fellows are reliably performing bladder neck division, urethral anastomosis, and beginning to learn the dissection of the neurovascular bundles. CONCLUSIONS We found that in a high-volume center for RALP, urologic oncology fellows can be trained to perform the procedure with no significant adverse impact on patient clinical outcomes.
