Resident duty hour regulation and patient safety: establishing a balance between concerns about resident fatigue and adequate training in neurosurgery

Trends in United States neurosurgery residency education and training over the last decade (2009-2019)

OBJECTIVE

Postgraduate training in medicine has been under scrutiny in the last 10 years, with a focus on improving residents' education. The aim of this study was to quantify trends in neurosurgery residency (NSR) training and education over the last 10 years.

METHODS

The authors assessed Accreditation Council for Graduate Medical Education (ACGME), National Resident Matching Program, and American Board of Neurological Surgeons records and searched PubMed to collate 2009-2019 data. Analyzed trends included residents' demographic data, programs' characteristics, graduation and attrition rates, match data, resident case logs, and qualitative educational curriculum changes.

RESULTS

Significant increases in residents' demographic data (p < 0.05) included the number of female residents (from 12.7% to 17.6%) and the absolute number of residents (from 1112 to 1462). Age (mean 28.8 years), ethnicity, and number of residents per program (mean 13 residents per program) were unchanged. There were 16 new ACGME NSR programs, with currently 115 programs nationwide. The number of applicants per year (324 applicants per year) and the matching rate (mean 64%) remained stable. The mean attrition rate of 2.6% (range 2%-4%) was higher than the mean 2.1% ACGME attrition rate, a rate that decreased from 3% in 2009 to 1.6% in 2019. Education curriculum changes aimed at the standardization of training across the US included residents' boot camp (2009), the Milestones project (2012), and mandatory 7-year training initiated in 2013. An increase in endovascular, functional, trauma, and spine resident caseload was noted. The number of yearly publications about US NSR education has significantly increased (p < 0.05).

CONCLUSIONS

NSR education has received greater attention over the last decade in the US. Standardization of training has been implemented. A steady number of students remain interested in neurosurgery, with an increased number of women entering the field. Attention to wellness, in addition to high-quality education, should be further assessed as a factor to improve the overall NSR training and retention rate.

Evidence-based practice of stereotactic radiosurgery: Outcomes from an educational course for neurosurgery and radiation oncology residents

Background:

As the field of brain and spine stereotactic radiosurgery (SRS) continues to grow, so will the need for a comprehensive evidence base. However, it is unclear to what degree trainees feel properly equipped to use SRS. We assess the perceptions and comfort level reported by neurosurgery and radiation oncology residents concerning the evidence-based practice of SRS.

Methods:

A continuing medical education (CME) course provided peer-reviewed updates regarding treatment with intracranial and spinal SRS. Presentations were given by neurosurgery and radiation oncology residents with mentorship by senior faculty. To gauge perceptions regarding SRS, attendees were surveyed. Responses before and after the course were analyzed using the Fisher’s exact test in R statistical software.

Results:

Participants reported the greatest knowledge improvements concerning data registries (P < 0.001) and clinical trials (P = 0.026). About 82% of all (n = 17) radiation oncology and neurosurgery residents either agreed or strongly agreed that a brain and spine SRS rotation would be beneficial in their training. However, only 47% agreed or strongly agreed that one was currently part of their training. In addition, knowledge gains in SRS indications (P = 0.084) and ability to seek collaboration with colleagues (P = 0.084) showed notable trends.

Conclusion:

There are clear knowledge gaps shared by potential future practitioners of SRS. Specifically, knowledge regarding SRS data registries, indications, and clinical trials offer potential areas for increased educational focus. Furthermore, the gap between enthusiasm for increased SRS training and the current availability of such training at medical institutions must be addressed.

Does work time limit for resident physician affect short-term treatment outcome and hospital length of stay in patients with spontaneous intracerebral hemorrhage?: a two-year experience at a single training hospital in South Korea

Objective

To compare short-term treatment outcomes at hospital discharge and hospital length of stay (LOS) in patients with spontaneous intracerebral hemorrhage (sICH) before and after introduction of resident physician work time limit (WTL).

Methods

We retrospectively reviewed consecutive patients treated for sICH at our institution between 2016 and 2019. Then we dichotomized these patients into two groups, pre-WTL and post-WTL. We analyzed demographic elements and clinical features, and hospital length of stay (LOS). We evaluated short-term outcome using modified Rankin scale score at hospital discharge and then divided it into “good” and “poor” outcome groups. We subsequently, compared short-term treatment outcome and hospital LOS between the pre-WTL and post-WTL groups.

Results

Out of 779 patients, 420 patients (53.9%) were included in the pre-WTL group, and 359 (46.1%) in post-WTL. The mortality rate in sICH patients was higher in the post-WTL group (pre-WTL; 13.6% vs. post-WTL; 17.3%), but there was no statistically significant difference in short-term outcome including mortality (p=0.332) between the groups. The LOS also, was not significantly different between the two groups (pre-WTL; 19.0 days vs. post-WTL; 20.2 days) (p=0.341). The initial Glasgow Coma Scale score, personal stroke history, and mean age were the only independent outcome predicting factors for patients with sICH.

Conclusions

Some neurosurgeons may expect poorer outcome for sICH after implementation of the WTL of the K-MHW for resident physician however, enforcement of the WTL did not significantly influence the short-term outcome and hospital LOS for sICH in our hospital. Further well-designed multi-institutional prospective studies on the effects of WTL in sICH patient outcome, are anticipated.

Understanding the Multidimensional Effects of Resident Duty Hours Restrictions: A Thematic Analysis of Published Viewpoints in Surgery

PURPOSE

Individuals representing various surgical disciplines have expressed concerns with the impact of resident duty hours (RDH) restrictions on resident education and patient outcomes. This thematic review of published viewpoints aimed to describe the effects of these restrictions in surgery.

METHOD

The authors conducted a qualitative systematic review of non-research-based literature published between 2003 and 2015. Articles were included if they focused on the RDH restrictions in surgery and resident wellness, health promotion, resident safety, resident education and/or training, patient safety, medical errors, and/or heterogeneity regarding training or disciplines. A thematic analysis approach guided data extraction. Contextual data were abstracted from the included articles to aid in framing the identified themes.

RESULTS

Of 1,482 identified articles, 214 were included in the review. Most were from authors in the United States (144; 67%) and focused on the 80-hour workweek (164; 77%). The emerging themes were organized into three overarching categories: (1) impact of the RDH restrictions, (2) surgery has its own unique culture, and (3) strategies going forward. Published opinions suggested that RDH restrictions alone are insufficient to achieve the desired outcomes and that careful consideration of the surgical training model is needed to maintain the integrity of educational outcomes.

CONCLUSIONS

Opinions from the surgical community highlight the complexity of issues surrounding the RDH restrictions and suggest that recent changes are not achieving all the desired outcomes and have resulted in unintended outcomes. From the perceptions of the various stakeholders in surgical education studied, areas for new policies were identified.

National Perspectives on the Training of Neurosurgery Residents in Stereotactic Radiosurgery

BACKGROUND

Despite the critical role played by neurosurgeons in performing radiosurgery, neurosurgery residents in Canada have limited exposure to radiosurgery during their training. A survey of neurosurgery residents and faculty along with radiation oncology faculty was conducted to analyze perspectives regarding incorporating formal radiosurgery training into the neurosurgery residency curriculum Methods: An online survey platform was employed. Descriptive statistics were used to summarize center and respondent characteristics. Categorical variables were compared using odds ratios and corresponding 95% confidence intervals. The chi-squared test was utilized to assess statistical significance. A value of p<0.05 was considered significant Results: The response rate was 31% (119/381); 87% (102/119) of respondents were from the neurosurgical specialty and 13% (17/119) from radiation oncology. Some 46% of residents (18/40) were "very uncomfortable" with radiosurgery techniques, and 57% of faculty (42/73) believed that dedicated radiosurgery training would be beneficial though impractical. No respondents felt that "no training" would be beneficial. A total of 46% of residents (19/41) felt that this training would be beneficial and that time should be taken away from other rotations, if needed, while 58% of faculty (42/73) and 75% (28/41) of residents believed that either 1 or 1-3 months of time dedicated to training in radiosurgery would suffice Conclusions: Canadian neurosurgeons are actively involved in radiosurgery. Despite residents anticipating a greater role for radiosurgery in their future, they are uncomfortable with the practice. With the indications for radiosurgery expanding, this training gap can have serious adverse consequences for patients. Considerations regarding the incorporation and optimal duration of dedicated radiosurgery training into the Canadian neurosurgery residency curriculum are necessary.

Association of Resident Duty Hour Restrictions on Mortality of Nervous System Disease and Disorder

BACKGROUND

The impact of the 2003 residency duty hour reform on patient care remains a debated issue.

OBJECTIVE

Determine the association between duty hour limits and mortality in patients with nervous system pathology.

METHODS

Via a retrospective cohort study using the Nationwide Inpatient Sample from 2000-2010, the authors evaluated in-hospital mortality status in those with a primary discharge level diagnosis of disease or disorder of the nervous system. Odds ratios were calculated, and Bonferroni corrected P values and confidence intervals were determined to account for multiple comparisons relating in-hospital mortality with teaching status of the hospital by year.

RESULTS

The pre-reform (2000-2002) and peri-reform (2003) periods revealed no significant difference between teaching and nonteaching hospital mortality (P > .99). The post-reform period (2004-2010) was dominated by years of significantly higher mortality rates in teaching hospitals compared to nonteaching hospitals: 2004 (P < .001); 2006 (P = .043); 2007 (P = .042); and 2010 (P = .003). However, data for 2005 (P ≥ .99), 2008 (P = .80), and 2009 (P = .09) did not show a significant difference in mortality.

CONCLUSIONS

Teaching and nonteaching hospital mortality was similar in patients with nervous system pathology prior to the duty hour reform. While nonteaching institutions demonstrated steadily declining mortality over the decade, teaching hospital mortality spiked in 2004 and declined at a more restricted rate. The timing of these changes could suggest a negative correlation of duty hour restrictions on outcomes of patients with nervous system pathology.

Implications of transitioning to a resident night float system in neurosurgery: mortality, length of stay, and resident experience

OBJECTIVE Many neurosurgical training programs have moved from a 24-hour resident call system to a night float system, but the impact on outcomes is unclear. Here, the authors compare length of stay (LOS) for neurosurgical patients admitted before and after initiation of a night float system at a tertiary care training hospital. METHODS The neurosurgical residency at the University of Alabama at Birmingham transitioned from 24-hour call to a night float resident coverage system in July 2013. In this cohort study, all patients admitted to the neurosurgical service for 1 year before and 1 year after this transition were compared with respect to hospital and ICU LOSs, adjusted for potential confounders. RESULTS A total of 4619 patients were included. In the initial bivariate analysis, night float was associated with increased ICU LOS (p = 0.032) and no change in overall LOS (p = 0.65). However, coincident with the transition to a night float system was an increased frequency of resident service transitions, which were highly associated with hospital LOS (p < 0.01) and ICU LOS (p < 0.01). After adjusting for resident service transitions, initiation of the night float system was associated with decreased hospital LOS (p = 0.047) and no change in ICU LOS (p = 0.35). CONCLUSIONS This study suggests that a dedicated night float resident may improve night-to-night continuity of care and decrease hospital LOS, but caution must be exercised when initiation of night float results in increased resident service transitions.

Effect of resident handoffs on length of hospital and intensive care unit stay in a neurosurgical population: a cohort study

OBJECT

Handoffs and services changes are potentially modifiable sources of medical error and delays in transition of care. This cohort study assessed the relationship between resident service handoffs and length of stay for neurosurgical patients.

METHODS

All patients admitted to the University of Alabama at Birmingham neurosurgical service between July 1, 2012, and July 1, 2014, were retrospectively identified. A service handoff was defined as any point when a resident handed off coverage of a service for longer than 1 weekend. A conditional probability distribution was constructed to adjust length of stay for the increasing probability of a random handoff. The Student t-test and ANCOVA were used to assess relationships between resident service handoffs and length of hospital stay, adjusted for potential confounders.

RESULTS

A total of 3038 patients met eligibility criteria and were included in the statistical analyses. Adjusted length of hospital stay (5.32 vs 3.53 adjusted days) and length of ICU stay (4.38 vs 2.96 adjusted days) were both longer for patients who experienced a service handoff, with no difference in mortality. In the ANCOVA model, resident service handoff remained predictive of both length of hospital stay (p < 0.001) and length of ICU stay (p < 0.001).

CONCLUSIONS

Occurrence of a resident service handoff is an independent predictor of length of hospital and ICU stay in neurosurgical patients. This finding is novel in the neurosurgical literature. Future research might identify mechanisms for improving continuity of care and mitigating the effect of resident handoffs on patient outcomes.

Graduating Pediatrics Residents' Reports on the Impact of Fatigue Over the Past Decade of Duty Hour Changes

OBJECTIVE

Concern about resident and patient safety has led to changes in Accreditation Council on Graduate Medical Education requirements over the past decade, with duty hour limitations in 2003 and 2011. This study examines pediatric residents' experiences on the impact of fatigue before, during, and after this time.

METHODS

An annual survey of graduating pediatrics residents was administered to a national, random sample in 2002, 2004, and 2013. Respondents were asked about the impact of fatigue. Multivariable logistic regression was conducted to compare differences between survey years.

RESULTS

The combined response rate for all 3 years was 62.6% (1,251 of 2,000). In multivariable analyses, residents were less likely in both 2004 and 2013 than in 2002 to fall asleep during an educational conference (adjusted odds ratio [aOR] 0.61, 95% confidence interval [CI] 0.41-0.91 and aOR 0.32, 95% CI 0.22-0.45, respectively) and to fall asleep while driving from work (aOR 0.55, 95% CI 0.37-0.81 and 0.43, 95% CI 0.31-0.60, respectively). Residents were less likely in 2004 than in 2002 to report making an error in patient care due to fatigue (aOR 0.46, 95% CI 0.27-0.76); however, in 2013 resident report of making an error in patient care due to fatigue returned to levels similar those reported in 2002.

CONCLUSIONS

Surveys of graduating pediatrics residents over the past decade (2002-2013) indicate overall reduced fatigue effects. During this same time frame, however, reports about making patient care errors improved but then returned to a level not significantly different from 2002, a finding warranting further exploration.

A History of Neurosurgery in Canada

Canada existed for more than half a century before there were glimmerings of modern neurosurgical activity. Neurosurgery had advanced significantly in Europe and the United States prior to its being brought to Toronto and Montreal from American centers. The pioneers responsible for the rapid evolution in practice, teaching and research are described. The interplay of scientific, professional, demographic and economic forces with general historical trends has produced dramatic changes in the way that neurosurgery is now practiced.

Morbidity, mortality, and health care costs for patients undergoing spine surgery following the ACGME resident duty-hour reform

Object

The Accreditation Council for Graduate Medical Education (ACGME) implemented resident duty-hour restrictions on July 1, 2003, in concern for patient and resident safety. Whereas studies have shown that duty-hour restrictions have increased resident quality of life, there have been mixed results with respect to patient outcomes. In this study, the authors have evaluated the effect of duty-hour restrictions on morbidity, mortality, length of stay (LOS), and charges in patients who underwent spine surgery.

Methods

The Nationwide Inpatient Sample was used to evaluate the effect of duty-hour restrictions on complications, mortality, LOS, and charges by comparing the prereform (2000–2002) and postreform (2005–2008) periods. Outcomes were compared between nonteaching and teaching hospitals using a difference-in-differences (DID) method.

Results

A total of 693,058 patients were included in the study. The overall complication rate was 8.6%, with patients in the postreform era having a significantly higher rate than those in the pre–duty-hour restriction era (8.7% vs 8.4%, p < 0.0001). Examination of hospital teaching status revealed complication rates to decrease in nonteaching hospitals (8.2% vs 7.6%, p < 0.0001) while increasing in teaching institutions (8.6% vs 9.6%, p < 0.0001) in the duty-hour reform era. The DID analysis to compare the magnitude in change between teaching and nonteaching institutions revealed that teaching institutions to had a significantly greater increase in complications during the postreform era (p = 0.0002). The overall mortality rate was 0.37%, with no significant difference between the pre– and post–duty-hour eras (0.39% vs 0.36%, p = 0.12). However, the mortality rate significantly decreased in nonteaching hospitals in the postreform era (0.30% vs 0.23%, p = 0.0008), while remaining the same in teaching institutions (0.46% vs 0.46%, p = 0.75). The DID analysis to compare the changes in mortality between groups revealed that the difference between the effects approached significance (p = 0.069). The mean LOS for all patients was 4.2 days, with hospital stay decreasing in nonteaching hospitals (3.7 vs 3.5 days, p < 0.0001) while significantly increasing in teaching institutions (4.7 vs 4.8 days, p < 0.0001). The DID analysis did not demonstrate the magnitude of change for each group to differ significantly (p = 0.26). Total patient charges were seen to rise significantly in the post–duty-hour reform era, increasing from $40,000 in the prereform era to $69,000 in the postreform era. The DID analysis did not reveal a significant difference between the changes in charges between teaching and nonteaching hospitals (p = 0.55).

Conclusions

The implementation of duty-hour restrictions was associated with an increased risk of postoperative complications for patients undergoing spine surgery. Therefore, contrary to its intended purpose, duty-hour reform may have resulted in worse patient outcomes. Additional studies are needed to evaluate strategies to mitigate these effects and assist in the development of future health care policy.

Use of the Electronic Health Record to Track Continuity of Care in Neurological Surgery Residency

BACKGROUND

Continuity of care in neurological surgery includes preoperative planning, technical and cognitive operative experience, and postoperative follow-up. Determining the extent of continuity of care with duty hour limits is problematic.

OBJECTIVE

We used electronic health record data to track continuity of care in a neurological surgery program and to assess changes in rotation requirements.

METHODS

The electronic health record was surveyed for all dictated resident-neurological surgery patient encounters (excluding progress notes), discharge summaries, and bedside procedures (July 2009-November 2011). Encounters were designated as preoperative, operative, or postoperative and were grouped by postgraduate year (PGY)-1 through PGY-6.

RESULTS

A total of 6382 dictations were reviewed, with 5231 (82.0%) pertinent to neurological surgery. Of the 1469 operative notes, 303 (20.6%) had a record of an encounter with the operating resident in either a postoperative or preoperative setting. Preoperative encounters totaled 10.1% (148 of 1469); postoperative, 5.1% (75 of 1469); and encounters with both were 5.4% (80 of 1469). Continuity of care was as follows: PGY-1, 13.8% (4 of 29); PGY-2, 17.4% (26 of 149); PGY-3, 29.0% (36 of 124); PGY-4, 24.8% (73 of 294); PGY-5, 28.8% (109 of 379); and PGY-6, 11.1% (55 of 494). One of the highest continuity rates was observed in a rotation specifically constructed to enhance continuity of care.

CONCLUSIONS

The electronic health record can be used to track resident continuity of care in neurological surgery. The primary operating resident saw the patient in nonoperative settings, such as general admission, clinic visitation, or consultation in 20.6% (303 of 1469) of cases.

Worse outcomes for patients undergoing brain tumor and cerebrovascular procedures following the ACGME resident duty-hour restrictions

OBJECT

On July 1, 2003, the Accreditation Council for Graduate Medical Education (ACGME) implemented duty-hour restrictions for resident physicians due to concerns for patient and resident safety. Though duty-hour restrictions have increased resident quality of life, studies have shown mixed results with respect to patient outcomes. In this study, the authors have evaluated the effect of duty-hour restrictions on morbidity, mortality, length of stay, and charges in patients who underwent brain tumor and cerebrovascular procedures.

METHODS

The Nationwide Inpatient Sample was used to evaluate the effect of duty-hour restrictions on complications, mortality, length of stay, and charges by comparing the pre-reform (2000-2002) and post-reform (2005-2008) periods. Outcomes were compared between nonteaching and teaching hospitals using a difference-in-differences (DID) method.

RESULTS

A total of 90,648 patients were included in the analysis. The overall complication rate was 11.7%, with the rates not significantly differing between the pre- and post-duty hour eras (p = 0.26). Examination of hospital teaching status revealed that complication rates decreased in nonteaching hospitals (12.1% vs 10.4%, p = 0.0004) and remained stable in teaching institutions (11.8% vs 11.9%, p = 0.73) in the post-reform era. Multivariate analysis demonstrated a significantly higher complication risk in teaching institutions (OR 1.33 [95% CI 1.11-1.59], p = 0.0022), with no significant change in nonteaching hospitals (OR 1.11 [95% CI 0.91-1.37], p = 0.31). A DID analysis to compare the magnitude in change between teaching and nonteaching institutions revealed that teaching hospitals had a significantly greater increase in complications during the post-reform era than nonteaching hospitals (p = 0.040). The overall mortality rate was 3.0%, with a significant decrease occurring in the post-reform era in both nonteaching (5.0% vs 3.2%, p < 0.0001) and teaching (3.2% vs 2.3%, p < 0.0001) hospitals. DID analysis to compare the changes in mortality between groups did not reveal a significant difference (p = 0.40). The mean length of stay for all patients was 8.7 days, with hospital stay decreasing from 9.2 days to 8.3 days in the post-reform era (p < 0.0001). The DID analysis revealed a greater length of stay decrease in nonteaching hospitals than teaching institutions, which approached significance (p = 0.055). Patient charges significantly increased in the post-reform era for all patients, increasing from $70,900 to $96,100 (p < 0.0001). The DID analysis did not reveal a significant difference between the changes in charges between teaching and nonteaching hospitals (p = 0.17).

CONCLUSIONS

The implementation of duty-hour restrictions correlated with an increased risk of postoperative complications for patients undergoing brain tumor and cerebrovascular neurosurgical procedures. Duty-hour reform may therefore be associated with worse patient outcomes, contrary to its intended purpose. Due to the critical condition of many neurosurgical patients, this patient population is most sensitive and likely to be negatively affected by proposed future increased restrictions.

An ACGME Duty Hour Compliant 3-Person Night Float System for Neurological Surgery Residency Programs

BACKGROUND

In 2003, the Accreditation Council for Graduate Medical Education (ACGME) instituted the 24+6-hour work schedule and 80-hour workweek, and in 2011, it enhanced work hour and supervision standards.

INNOVATION

In response, Oregon Health & Science University's (OHSU) neurological surgery residency instituted a 3-person night float system.

METHODS

We analyzed work hour records and operative experience for 1 year before and after night float implementation in a model that shortened a combined introductory research and basic clinical neurosciences rotation from 12 to 6 months. We analyzed residents' perception of the system using a confidential survey. The ACGME 2011 work hour standards were applied to both time periods.

RESULTS

AFTER NIGHT FLOAT IMPLEMENTATION, THE NUMBER OF DUTY HOUR VIOLATIONS WAS REDUCED: 28-hour shift (11 versus 235), 8 hours off between shifts (2 versus 20), 80 hours per week (0 versus 17), and total violations (23 versus 275). Violations increased only for the less than 4 days off per 4-week interval rule (10 versus 3). No meaningful difference was seen in the number of operative cases performed per year at any postgraduate year (PGY) training level: PGY-2 (336 versus 351), PGY-3 (394 versus 354), PGY-4 (803 versus 802), PGY-5 (1075 versus 1040), PGY-7 (947 versus 913), and total (3555 versus 3460). Residents rated the new system favorably.

CONCLUSIONS

To meet 2011 ACGME duty hour standards, the OHSU neurological surgery residency instituted a 3-person night float system. A nearly complete elimination of work hour violations did not affect overall resident operative experience.

Delinking resident duty hours from patient safety

Patient safety is a powerful motivating force for change in modern medicine, and is often cited as a rationale for reducing resident duty hours. However, current data suggest that resident duty hours are not significantly linked to important patient outcomes. We performed a narrative review and identified four potential explanations for these findings. First, we question the relevance of resident fatigue in the creation of harmful errors. Second, we discuss factors, including workload, experience, and individual characteristics, that may be more important determinants of resident fatigue than are duty hours. Third, we describe potential adverse effects that may arise from--and, therefore, counterbalance any potential benefits of--duty hour reductions. Fourth, we explore factors that may mitigate any risks to patient safety associated with using the services of resident trainees. In summary, it may be inappropriate to justify a reduction in working hours on the grounds of a presumed linkage between patient safety and resident duty hours. Better understanding of resident-related factors associated with patient safety will be essential if improvements in important patient safety outcomes are to be realized through resident-focused strategies.

Experience With a Simulator-Based Angiography Course for Neurosurgical Residents

BACKGROUND:

Simulation is an increasingly useful means of teaching in the era of duty hour restrictions. Since the completion of our diagnostic cerebral angiography simulator curriculum pilot program, we have performed this resident course at 2 Congress of Neurological Surgeons (CNS) annual meetings with larger participant numbers.

OBJECTIVE:

To report the ongoing results of these courses.

METHODS:

A 120-minute simulator-based training course was performed at 2 CNS annual meetings. Precourse written and simulator skills assessments were performed, followed by instructor-guided training on an endovascular simulator. Postcourse written and simulator practical assessments were then performed and compared with precourse scores.

RESULTS:

Thirty-seven neurosurgery resident participants completed the course module: 16 completed the first course provided and 21 completed the second. Posttest written scores were significantly higher than pretest scores (mean ± SEM, 8.5 ± 0.40.3 vs 4.9 ± 0.3; P &lt; .001). Instructor assessments of practical posttest scores of participants were significantly higher than pretest practical scores for both the CNS 2011 and CNS 2012 groups (P &lt; .001).

CONCLUSION:

The expansion of a curriculum-based, cerebral angiography simulator pilot program to trainees through courses at national neurosurgical meetings demonstrated excellent results with significant improvements in written test scores and instructor assessments of participant technical skills. With ever-expanding improvements in simulation technology and realism, simulator training for cerebral angiography may become an integral component of resident training in the future.

New shift models for doctors in a large German University Neurosurgery Department: how they comply with the European Working Time Directive 3 years after implementation

BACKGROUND

Due to the European Working Time Directive (EWTD) and a new collective agreement for doctors working at University hospitals in 2006 new shift models had to be designed in the Department of Neurosurgery of the University Hospital Tübingen, Germany. The aim of the study was to show the fit of the models regarding the average weekly working time limits (aWTL), the daily maximum of 10-h working time (10-h dWT), and the staff expenditures 3 years after implementation.

METHODS

The new shift model was implemented in 2008, and hence planning and documentation were done electronically. Adherence to the work schedules was measured, and aWTL adherence rates were compared. The relative number of 10-h dWT violations in 2009 and 2010 was analysed. Staff costs relative to performance before and after implementation were calculated and tested using analysis of variance (ANOVA). Four other departments without alteration of shift models served as a control group in cost trend analysis.

RESULTS

In 2010 all doctors in the Department of Neurosurgery were able to stay within the limit of 54 h/week; one doctor without opt-out exceeded the 48 h/week limit (50.1 h/week). The median per capita rate of 10-h dWT violations in 2009 was 20.3 % of all eligible working days and further declined to 10.7 % in 2010 (p < 0.001). Staff costs per case-weight point did not change significantly (2007: 339.88€, 2009: 307.99€, 2010: 322.54€; p = 0.22) in neurosurgery or in the control group (2007: 633.72€, 2009: 637.06€, 2010: 690.30€; p = 0.67).

CONCLUSIONS

After implementation of the new shift model, current monitoring and properly matching modifications led to long-term stability in complying with the EWTD regulations without increasing costs for staff expenditures.

Duty hours, quality of care, and patient safety: general surgery resident perceptions

BACKGROUND

The balance between patient treatment risks and training residents to proficiency is confounded by duty-hour limits. Stricter limits have been recommended to enhance quality and safety, although supporting data are scarce.

STUDY DESIGN

A previously piloted survey was delivered with the 2010 American Board of Surgery In-Training Examination (ABSITE). First postgraduate year (PGY1) and PGY2 trainees took the Junior examination (IJE); PGY3 and above took the Senior examination (ISE). Residency type, size, and location were linked to examinees using program codes. Five survey items queried all residents about the impact of further hour limits on care quality; online test residents answered 7 more items probing medical error sources. Data were analyzed using factorial ANOVA for association with sex, PGY level, and program demographics.

RESULTS

There were 6,161 categorical surgery residents who took the ABSITE: 60% men, 60% ISE, and two-thirds in university programs. Paper (n = 5,079) and online (n = 1,082) examinees were similar. Item response rates ranged from 91% to 98%. Few (<25%) perceived that stricter hour limits would improve care quality to a large or maximal extent. IJE plus West and Northeast residents significantly more often favored fewer hours. Factors perceived as contributing to medical errors usually or always by ≥ 15% of residents were incomplete handoffs, inexperience or lack of knowledge, insufficient ancillary personnel, and excessive workload.

CONCLUSIONS

Most categorical surgery residents do not perceive that reduced duty hours will noticeably improve quality of care. Resident perceptions of causes of medical errors suggest that system changes are more likely to enhance patient safety than further hour limits.

Results of a national neurosurgery resident survey on duty hour regulations

BACKGROUND

The Accreditation Council for Graduate Medical Education (ACGME) duty hour standards that began July 2011 will further limit resident duty hours.

OBJECTIVE

To survey neurosurgery residents in the United States on duty hour violations under the current system and the predicted effects on education and patient safety of the new regulations.

METHODS

Surveys were mailed to every neurosurgery training program in the United States and Puerto Rico. Program directors and coordinators were asked to distribute surveys to their residents.

RESULTS

Three hundred seventy-seven neurosurgery residents mailed surveys back to the study center (34% response rate). More than one-third of respondents reported violating the 80-hour rule occasionally or frequently (36%). Thirty-one residents (8%) reported having been involved in a motor vehicle collision or life-threatening event and 20 (6%) reported having made a medical error resulting in patient harm after an extended shift. Eighty-three percent disagreed with the 16-hour proposed regulation for postgraduate year 1. The majority of respondents thought that the new standards will have a negative or strongly negative effect on their residency training (72%).

CONCLUSION

This national duty hour survey of neurosurgical residents reveals considerable concern over the new ACGME proposed standards. The majority of respondents believe that the new standards will have a negative effect on their residency training. Furthermore, this survey indicates an overwhelming negative attitude toward mandated duty hour regulations among neurosurgical residents. Duty hour violations reported in this survey may be a more honest depiction of true violations than previous surveys and are higher than expected.

Approach-specific multi-grid anatomical modeling for neurosurgery simulation with public-domain and open-source software

We present on-going work on multi-resolution sulcal-separable meshing for approach-specific neurosurgery simulation, in conjunction multi-grid and Total Lagrangian Explicit Dynamics finite elements. Conflicting requirements of interactive nonlinear finite elements and small structures lead to a multi-grid framework. Implications for meshing are explicit control over resolution, and prior knowledge of the intended neurosurgical approach and intended path. This information is used to define a subvolume of clinical interest, within some distance of the path and the target pathology. Restricted to this subvolume are a tetrahedralization of finer resolution, the representation of critical tissues, and sulcal separability constraint for all mesh levels.

Conceptual frameworks in the study of duty hours changes in graduate medical education: a review

PURPOSE

Conceptual frameworks are approaches to a research problem that specify key entities and their relationships. The 2009 Institute of Medicine (IOM) report on resident duty hours, subsequent studies, and published responses to the report present a variety of conceptual frameworks for the study of the impact of duty hours regulations. The authors sought to identify and describe these conceptual frameworks and their implications.

METHOD

The authors reviewed the IOM report and articles in both peer-reviewed and non-peer-reviewed literature for the period January 2008 through April 2010, identified using multiple electronic databases including PubMed, EMBASE, CINAHL, BEME, and PsycInfo. Studies that explicitly described or argued for the effect of resident duty hours on any other outcome, as judged by consensus of multiple reviewers, were included. The authors selected 239 of 858 studies reviewed. Several of the authors reviewed articles to identify conceptual frameworks used implicitly or explicitly to describe the relationship between duty hours (or duty hours regulations) and outcomes. Identification was by consensus.

RESULTS

Twenty-three conceptual frameworks were identified. Several made contradictory predictions about the impact of duty hours regulations on patient outcomes, resident education, and other key outcomes.

CONCLUSIONS

The concept of duty hours itself is contested, and little attention has been paid to the nature and intensity of the activities that occupy residents' hours. Much research focuses on isolated outcomes of duty hours changes without considering mediation or moderation. More studies are needed to define trade-offs between outcomes and the value society places on these trade-offs.

The first 50s: can we achieve acceptable results in vestibular schwannoma surgery from the beginning?

OBJECTIVE

Vestibular schwannoma surgery requires a profound knowledge of anatomy and long-standing experience of surgical skull base techniques, as patients nowadays requests high-quality results from any surgeon. This educes a dilemma for the young neurosurgeon as she/he is at the beginning of a learning curve. The presented series should prove if surgical results of young skull base surgeons are comparable respecting carefully planned educational steps.

METHODS

The first 50 vestibular schwannomas of the first author were retrospectively evaluated concerning morbidity and mortality with an emphasis on functional cranial nerve preservation. The results were embedded in a timeline of educational steps starting with the internship in 1999.

RESULTS

Fifty vestibular schwannomas were consecutively operated from July 2007 to January 2010. According to the Hannover Classification, 14% were rated as T1, 18% as T2, 46% as T3, and 21% as T4. The overall facial nerve preservation rate was 96%. Seventy-nine percent of patients with T1-T3 tumours had no facial palsy at all and 15% had an excellent recovery of an initial palsy grade 3 according to the House & Brackman scale within the first 3 months after surgery. Hearing preservation in T1/2 schwannomas was achieved in 66%, in patients with T3 tumours in 56%, and in large T4 tumours in 25%. Three patients suffered a cerebrospinal fluid fistula (6%), and one patient died during the perioperative period due to cardiopulmonary problems (2%).

CONCLUSIONS

The results demonstrate that with careful established educational plans in skull base surgery, excellent clinical and functional results can be achieved even by young neurosurgeons.

Resident perceptions of radiosurgical training and the effect of a focused resident training seminar

OBJECT

Neurosurgical training is critical in providing residents with the skill set, knowledge, and confidence to perform challenging neurosurgical procedures. Radiosurgery, which neurosurgeons helped define and refine, differs from more traditional, open neurosurgical approaches. This study evaluates the opinions of residents on current radiosurgical training and the effect of a focused educational course on those residents.

METHODS

The American Association of Neurological Surgeons sponsored a 3-day course focused on intracranial and spinal radiosurgery. Senior-level residents were nominated by US program directors to participate in the course. Twenty-eight residents from distinct training programs were surveyed before and after the course to discern current training practices in radiosurgery and the effect of the focused educational program. The median training level of the participants was postgraduate Year 5 (mean 5.3 years, range 3-7 years).

RESULTS

Two-thirds of residents reported that their training institutions had no formal radiosurgery rotation. Twenty-five percent planned to obtain postresidency fellowship training that would include radiosurgery. Before the course, 79% of the residents expected to include radiosurgery in their practice. However, prior to the course, those describing themselves as "very uncomfortable" with performing intracranial or spinal radiosurgery were 33.3 and 45.8%, respectively. After the course, mean self-assessment scores for understanding the indications and performing intracranial radiosurgery increased by 43 and 89%, respectively. The mean scores for understanding the indications and comfort with performing spinal radiosurgery increased by 79 and 200%, respectively. Following the course, there was a 12.3% increase in the number of residents planning to perform radiosurgery following residency.

CONCLUSIONS

Current neurosurgical residents appear uneasy about their grasp of radiosurgical indications and their ability to perform the procedure. Focused training courses sponsored by professional societies may improve resident education and training in this area of neurosurgery, which has a skill set and basis of knowledge different from traditional open neurosurgical procedures. Further evaluation of the radiosurgical training process for residents must be performed so as to ensure competency and sufficient workforce to meet expanding demands for neurosurgeons performing radiosurgery in a multidisciplinary climate.

Step-by-step education of the retrosigmoid approach leads to low approach-related morbidity through young residents

BACKGROUND

Neurosurgery requires a profound knowledge of anatomy and surgical skills. The skull base approach is the crucial step for successful intradural performance. Resident training at experienced institutions must consider this background when educating young neurosurgeons.

METHODS

From 2006-2008, 223 retrosigmoid approaches for various cerebellopontine angle pathologies have been performed at the Department of Neurosurgery Eberhard-Karls-University, Tübingen. After a minimum time of 6 months assisting, followed by participation of dissection courses and continuous anatomical training, later performing their first approaches under direct supervision of an experienced surgeon, residents perform their first retrosigmoid approaches autonomously in the operating theatre. With this study, we evaluate the surgical morbidity and the time factor related to the educational level of the surgeon.

RESULTS

Comparing surgical-related morbidity between approaches performed by experienced neurosurgeons (>100 procedures) and young residents (<20 procedures), we found no significant differences concerning the incidence of cerebrospinal fluid fistulae, sinus lacerations, wound infections, cranioplasty dislocations, or occipital nerve neuromas. Even the mean time for the procedure (positioning, time-to-dural incision) was not significantly longer in the trainee group.

CONCLUSION

Respecting the stepwise educational levels for skull base surgery, including microanatomical studies, educational courses, and expert guidance at surgery, the retrosigmoid approach can be performed by young residents without increased morbidity at experienced institutions.

The response of the APPD, CoPS and AAP to the Institute of Medicine report on resident duty hours

In December 2008, the Institute of Medicine published new recommendations regarding duty hours and supervision of residents' training in the United States. These recommendations evoked immediate concerns from program directors and leadership in all surgical and medical disciplines, including pediatrics. To address these concerns, the Accreditation Council for Graduate Medical Education convened a Duty Hours Congress in Chicago, Illinois, on June 11 and 12, 2009. This report summarizes the opinions and testimony of the organizations (American Academy of Pediatrics, Association of Pediatric Program Directors, and Council of Pediatric Specialties) that were invited to represent pediatrics at the Duty Hours Congress. The American Academy of Pediatrics, the Association of Pediatric Program Directors, and the Council of Pediatric Specialties supported the basic principles of the Institute of Medicine report regarding patient safety, resident supervision, resident safety, and the importance of effective "hand-offs"; however, the organizations opposed additional reductions in resident duty hours given the potential unintended adverse effects on the competency of trainees, the costs of graduate medical education, and the future pediatric workforce. These organizations agreed that additional changes in graduate medical education must be data driven and consider residents within the broader system of health care. The costs and benefits must be carefully analyzed before implementing the Institute of Medicine recommendations.
