Increasing medical student confidence in gender and sexual health through a student-initiated lecture series.

INTRODUCTION: Medical students self-report insufficient training in topics of gender and sexuality in medicine, which may ultimately lead to negative health outcomes in patients for whom they will provide care. This study aims to identify whether a student-initiated lecture series on topics related to gender and sexual health leads to greater student comfort with discussing topics related to diverse sexual content. METHODS: Medical students matriculated during two consecutive academic years were invited to participate in the lecture series. Investigators administered anonymous pre- and post-series surveys (n=152 and 105 respondents, respectively) using google forms. Respondents rated their comfort levels discussing relevant topics and provided narrative feedback concerning strengths and areas for improvement of the lecture series. Overlaps between the 95% confidence intervals around pre- and post-series percentage of students comfortable/very comfortable discussing each topic were examined to compare pre- vs post-series comfort ratings. Narrative comments were reviewed for thematic feedback. RESULTS: 105 medical students completed the lecture series, with 80% identifying as female. Self-assessed comfort levels across all seminar topics were greater in post- versus pre-lecture series surveys with the following topics showing the biggest differences (percentage of students "somewhat" or "very" comfortable [95% confidence intervals]: discussing sexuality with gender (68%[59-77] vs. 29%[22-36]) and sexual minority patients (84%[77-91] vs. 49%[41-57]), HIV prevention counseling (70%[61-78] vs. 20% [20-34]), identifying female genital cutting (44% [34-53] vs. 11%[6-16]), and discussing intimate partner violence (65%[55-74] vs. 33%[25-40]). Qualitative analysis indicated respondents found the lectures to be effective and believed they should be integrated into the required medical school curriculum. CONCLUSION: Our student-initiated lecture series was associated with greater student comfort discussing topics related to gender and sexuality with patients. This framework represents a useful method to address gaps in medical education and has the potential to improve health outcomes in multiple populations.

Epidemiology of Sports Related Concussion in Brazilian Jiu-Jitsu: A Cross-Sectional Study.

Brazilian Jiu-Jitsu (BJJ) is a rapidly growing grappling sport with a wide spectrum of participants. This cross-sectional study examined the lifetime prevalence of concussion in adult BJJ practitioners in the United States using a 17-item survey. A total of 778 (11.4% female) BJJ practitioners with a median age of 31 years completed the survey. Overall, the lifetime prevalence of the self-reported BJJ-related concussion was 25.2%. However, the prevalence was higher among females than males (43.0% versus 22.9%; X²(1,740) = 15.129; p < 0.001). Factors independently associated with significantly increased odds of having sustained a BJJ-related concussion included a prior history of concussion (OR 1.76, 95% CI 1.14⁻2.74; p = 0.011) and female gender (OR 1.95, 95% CI 1.04⁻3.65; p = 0.037). The median return to sports time was three days, with 30.3% of participants returning on the same day as being concussed. The present study represents the first epidemiological research examining the concussions in BJJ. The results underscore the need for increased education on concussions and return to sports guidelines among BJJ coaches and practitioners.

Validation of the Omni: A Novel, Multimodality, and Longitudinal Surgical Skills Assessment.

OBJECTIVE: The breadth of technical skills included in general surgery training continues to expand. The current competency-based training model requires assessment tools to measure acquisition, learning, and mastery of technical skill longitudinally in a reliable and valid manner. This study describes a novel skills assessment tool, the Omni, which evaluates performance in a broad range of skills over time. DESIGN: The 5 Omni tasks, consisting of open bowel anastomosis, knot tying, laparoscopic clover pattern cut, robotic needle drive, and endoscopic bubble pop, were developed by general surgery faculty. Component performance metrics assessed speed, accuracy, and quality, which were scaled into an overall score ranging from 0 to 10 for each task. For each task, ANOVAs with Scheffé's post hoc comparisons and Pearson's chi-squared tests compared performance between 6 resident cohorts (clinical years (CY1-5) and research fellows (RF)). Paired samples t-tests evaluated changes in performance across academic years. Cronbach's alpha coefficient determined the internal consistency of the Omni as an overall assessment. SETTING: The Omni was developed by the Department of Surgery at Duke University. Annual assessment and this research study took place in the Surgical Education and Activities Lab. PARTICIPANTS: All active general surgery residents in 2 consecutive academic years spanning 2015 to 2017. RESULTS: A total of 62 general surgery residents completed the Omni and 39 (67.2%) of those residents completed the assessment in 2 consecutive years. Based on data from all residents' first assessment, statistically significant differences (p < 0.05) were observed among CY cohorts for bowel anastomosis, robotic, and laparoscopic task metrics. By pair-wise comparisons, mean bowel anastomosis scores distinguished CY1 from CY3-5 and CY2 from CY5. Mean robotic scores distinguished CY1 from RF, and mean laparoscopic scores distinguished CY1 from RF, CY3, and CY5 in addition to CY2 from CY3. Mean scores in performance on the knot tying and endoscopic tasks were not significantly different. Statistically significant improvement in mean scores was observed for all tasks from year 1 to year 2 (all p < 0.02). The internal consistency analysis revealed an alpha coefficient of 0.656. CONCLUSIONS: The Omni is a novel composite assessment tool for surgical technical skill that utilizes objective measures and scoring algorithms to evaluate performance. In this pilot study, 3 tasks demonstrated discriminative ability of performance by CY, and all 5 tasks demonstrated construct validity by showing longitudinal improvement in performance. Additionally, the Omni has adequate internal consistency for a formative assessment. These results suggest the Omni holds promise for the evaluation of resident technical skill and early identification of outliers requiring intervention.

Systemic blood pressure trends and antihypertensive utilization following continuous-flow left ventricular assist device implantation: an analysis of the interagency registry for mechanically assisted circulatory support.

BACKGROUND: Elevated systemic blood pressure (SBP) has been linked to complications in Continuous-flow left ventricular assist devices (CF-LVADs), including stroke and pump thrombosis. We queried Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) to describe the response of SBP to CF-LVAD implantation and to delineate contemporary trends in antihypertensive (AH) utilization for patients with these pumps. METHODS: We identified all CF-LVAD implantations in patients older than 18 years from 2006-2014, excluding those whose durations were less than 30 days. Pre-implant patient demographics and characteristics were obtained for each record. SBPs [i.e., mean arterial pressures (MAPs)], AH-use data, and vital status were tabulated, extending up to 5 years following implantation. RESULTS: A total of 10,329 CF-LVAD implantations were included for study. Post-implant, SBPs increased rapidly during the first 3 months but plateaued thereafter; AH utilization mirrored this trend. By 6 months, mean MAPs climbed 12.2% from 77.6 mmHg (95% CI: 77.4-77.8) pre-implantation to 87.1 mmHg (95% CI: 86.7-87.4) and patients required a mean of 1.8 AH medications (95% CI: 1.75-1.78) -a 125% increase from AH use at 1-week post-implantation (0.8 AHs/patient, 95% CI: 0.81-0.83) but a 5.3% decrease from pre-implant utilization (1.9 AHs/patient, 95% CI: 1.90-1.92). Once medication changes stabilized, the most common AH regimens were lone beta blockade (15%, n=720) and a beta blocker plus an ACE inhibitor (14%, n=672). CONCLUSIONS: SBP rises rapidly after CF-LVAD implantation, stabilizing after 3 months, and is matched by concomitant changes in AH utilization; this AH use has increased over consecutive implant years.

American College of Surgeons Resident Objective Structured Clinical Examination: a national program to assess clinical readiness of entering postgraduate year 1 surgery residents.

OBJECTIVE: This report describes the development, initial implementation, and reliability of American College of Surgeons Resident Objective Structured Clinical Examination (ACS OSCE). BACKGROUND: Variability in clinical knowledge and skills of entering surgery residents has been demonstrated. The ACS OSCE was developed to evaluate and help remediate residents' knowledge and skills in managing patients with life-threatening conditions. METHODS: A task force of surgeons and professional educators developed 10 standardized clinical case stations, evaluation checklists, and rating scales. Standardized patients (SPs) evaluated each resident's clinical skills (history taking, physical examination, communication, and SP-global scores). Residents completed checklists on diagnosis and management. Coefficient alpha and item-total correlations were used, respectively, to assess internal consistency of metrics and station validity. The resident's overall performance for each station was calculated by combining scores of the individual skills. Analysis of variance compared performance across different institutions. RESULTS: A total of 103 postgraduate year 1 residents from 7 institutions completed the OSCE. Reliability coefficients of skills ranged from 0.38 for diagnosis to 0.68 for global scores. For overall performance on individual stations, the reliability coefficients ranged from 0.51 to 0.82. Using total percent correct scores from highly reliable stations (α > 0.8), wide variability in resident performance was demonstrated within and between the 7 institutions. CONCLUSIONS: The ACS OSCE was successfully implemented across diverse institutions. It had moderate reliability and demonstrated variability among entering surgery residents. The ACS OSCE is now available for broader implementation. It should help reduce resident variability and address the requirements of Accreditation Council for Graduate Medical Education for resident supervision.

Advanced surgical skills for exposure in trauma: a new surgical skills cadaver course for surgery residents and fellows.

BACKGROUND: Surgical education is changing owing to workforce and economic demands. Simulation and other technical teaching methods are used to acquire skills transferable to the operating room. Operative management of traumatic injuries has declined, making it difficult to acquire and maintain competence. The ASSET course was developed by the Committee on Trauma's Surgical Skills Committee to fill a surgical skills need in resident and fellow education. Using a human cadaver, standardized rapid exposure of vital structures in the extremities, neck, thorax, abdomen, retroperitoneum, and pelvis is taught. METHODS: A retrospective analysis of 79 participants in four ASSET courses was performed. Operative experience data were collected, and self-efficacy questionnaires (SEQs) were administered before and after the course. Course evaluations and instructor evaluation data were analyzed. Student's and paired samples t tests as well as analysis of variance and Spearman ρ correlation coefficient analysis were performed using α at p < 0.05. We hypothesized that the ASSET course would teach new surgical techniques and that learner self-assessed ability would improve. RESULTS: Participants included 27 PGY-4, 20 PGY-5, 24 PGY-6 or PGY-7 and PGY-8 at other levels of training. Self-assessed confidence improved in all body regions (p < 0.001), with the greatest increase in upper extremity and chest. Pre- and post-SEQ scores correlated with trauma operative experience. Precourse SEQ scores differed by level of training. Instructor evaluations correlated with previous experience on a trauma service. Program evaluations averaged 4.73 on a 5-point scale, with gaining new knowledge rated at 4.8 and learning new techniques at 4.72. CONCLUSION: A standardized cadaver-based surgical exposures course offered to senior surgical residents adds new surgical skills and improves participant self-assessed ability to perform emergent surgical exposure of vital structures.

Mechanism of injury predicts case fatality and functional outcomes in pediatric trauma patients: the case for its use in trauma outcomes studies.

BACKGROUND/PURPOSE: The mechanism of injury (MOI) may serve as a useful adjunct to injury scoring systems in pediatric trauma outcomes research. The objective is to determine the independent effect of MOI on case fatality and functional outcomes in pediatric trauma patients. METHODS: Retrospective review of pediatric patients ages 2 to 18 years in the National Trauma Data Bank from 2002 through 2006 was done. Mechanism of injury was classified by the International Classification of Diseases, Ninth Revision, E codes. The main outcome measures were mortality, discharge disposition (home vs rehabilitation setting), and functional impairment at hospital discharge. Multiple logistic regression was used to adjust for injury severity (using the Injury Severity Score and the presence of shock upon admission in the emergency department), age, sex, and severe head or extremity injury. RESULTS: Thirty-five thousand ninety-seven pediatric patients in the National Trauma Data Bank met inclusion criteria. Each MOI had differences in the adjusted odds of death or functional disabilities as compared with the reference group (fall). The MOI with the greatest risk of death was gunshot wounds (odds ratio [OR], 3.52; 95% confidence interval [CI], 2.23-5.54 95). Pediatric pedestrians struck by a motor vehicle have the highest risk of locomotion (OR, 3.30; 95% CI, 2.89-3.77) and expression (OR, 1.65; 95% CI, 1.22-2.23) disabilities. CONCLUSION: Mechanism of injury is a significant predictor of clinical and functional outcomes at discharge for equivalently injured patients. These findings have implications for injury prevention, staging, and prognosis of traumatic injury and posttreatment planning.

Geriatric motor vehicle collision survival: the role of institutional trauma volume.

BACKGROUND: Links between trauma center volumes and outcomes have been inconsistent in previous studies. This study examines the role of institutional trauma volume parameters in geriatric motor vehicle collision (MVC) survival. METHODS: The New York Statewide Planning and Research Cooperative Systems database was analyzed for all trauma admissions to state-designated Level I and II trauma centers from 1996 to 2003. For each center, the volume of patients was calculated in each of the following four categories: Young adult (age, 17-64 years) MVC and non-MVC, and geriatric (65 years and older) MVC and non-MVC. Logistic regression analysis was used to predict patient survival to hospital discharge based on the four volume parameters of the center at which they were treated, age, gender, ICISS, year of admission, and type of center. RESULTS: Five thousand three hundred sixty-five geriatric MVC victims were admitted to Level I (n = 3,541) or II (n = 1,824) centers in New York State excluding New York City. Four thousand eight hundred ninety-eight (91%) patients were discharged alive. Volume of geriatric MVC at the center at which the patient was treated was an independent significant predictor of survival (odds ratio, 32.6; 95% confidence interval, 2.8-377.0; p = 0.005) as were younger age, female gender, increased ICISS, and later year of discharge. Young adult non-MVC volume was an independent significant predictor of nonsurvival of geriatric patients (odds ratio, 0.8; 95% confidence interval, 0.64-0.99; p = 0.042). Type of center was unrelated to outcome. CONCLUSIONS: There may be a risk-adjusted survival advantage for geriatric MVC patients treated at trauma centers with relatively higher volumes of geriatric MVC trauma and lower volumes of young adult non-MVC trauma. These results support consideration of age in trauma center transfer criteria.

Women in surgery residency programs: evolving trends from a national perspective.

BACKGROUND: Similar numbers of men and women are currently graduating from United States (US) medical schools; therefore, surgery residency programs need to attract graduates of both genders. This study compared gender distributions of allopathic US medical graduates (USMG) from academic years 1999-2000 through 2004-2005. In addition, the gender distributions of USMG and international medical graduates (IMG; analyzed separately) entering accredited general surgery (GS) programs and USMG entering other surgical specialty programs were compared across academic years 2000-2001 through 2005-2006. STUDY DESIGN: Data were extracted from the American College of Surgeons Resident Master File and the Association of American Medical Colleges FACTS Website and Data Warehouse. Chi-square statistics compared gender distributions across years for all USMG graduating and applying to GS programs each year between 1999-2000 and 2004-2005 and for USMG and IMG entering training between 2000-2001 and 2005-2006. RESULTS: During the study period, the proportion of women increased significantly (p < 0.001) among USMG (43% to 47%), USMG applying to GS programs (27% to 33%), and USMG entering GS residencies (32% to 40%); the percentages of women among IMG entering GS residencies ranged from 11% to 18%, with no apparent linear increase. Proportions of women among USMG entering training increased in most surgical specialties examined. CONCLUSIONS: The gender gap among USMG entering GS training appears to be closing, concurrent with that of USMG overall during the study period. Surgery programs must continue to recruit and retain women to attract the best and brightest trainees.

Preimplementation predictors of website use: preliminary findings from the SCORE portal pilot study.

BACKGROUND: in 2008, the Surgical Council on Resident Education selected 33 residency programs to pilot its General Surgery Resident Curriculum Website Portal. The portal aims to reduce program variability in curricula, align teaching and learning with essential content, and improve resident study and performance. METHODS: two online surveys were sent to all program directors and their residents before releasing the portal. Data from 32 programs and 899 residents (84%) were analyzed to determine the extent to which preimplementation characteristics supported the portal's rationale and illuminated barriers to its use and impact on learning. RESULTS: the need for curriculum content and access to online texts varied markedly across programs. Residents had easy onsite access to the Internet and used it heavily for immediate purposes. Fewer residents used the Web for planned activities and proactive study. On average, residents reported studying an hour or less a day. CONCLUSIONS: the portal appears to serve curricular resource needs and may better direct resident study. Programs are advised to consciously integrate the SCORE curriculum and portal into residency training and faculty development.

Promoting self-efficacy in minimally invasive surgery training.

Many surgeons continue to actively pursue surgical approaches that are less invasive for their patients. This pursuit requires the surgeon to adapt to new instruments, techniques, technologies, knowledge bases, visual perspectives, and motor skills, among other changes. The premise of this paper is that surgeons adopting minimally invasive approaches are particularly obligated to maintain an accurate perception of their own competencies and learning needs in these areas (ie, self-efficacy). The psychological literature on the topic of self-efficacy is vast and provides valuable information that can help assure that an individual develops and maintains accurate self-efficacy beliefs. The current paper briefly summarizes the practical implications of psychological research on self-efficacy for minimally invasive surgery training. Specific approaches to training and the provision of feedback are described in relation to potential types of discrepancies that may exist between perceived and actual efficacy.

Efforts to enhance operating room teaching.

OBJECTIVE: To identify the learning needs of faculty members who are not perceived by residents as outstanding teachers in the operating room. DESIGN: General surgery residents electronically evaluated each faculty surgeon with whom they had significant contact upon completion of each clinical rotation between July 2005 and October 2006. Evaluation forms requested global ratings (1-5 scale ranging from poor to excellent) in 10 separate teaching-related areas, 1 of which was operating room teaching. Residents also rated faculty on 10 specific operating room teaching behaviors identified during a previous observational study. RESULTS: In total, 134 faculty surgeons were evaluated by 63 residents. Faculty who were evaluated by at least 5 residents (n = 99) were included in the study (mean = 21.9; range, 5-118 evaluations). The ratings of overall operating room teaching (M +/- SD: 4.46 +/- 0.52) correlated significantly (p < 0.001) with ratings of overall performance (r = 0.80) and each of the 10 teaching behaviors (range, r = 0.65 {confident in role as teacher and surgeon} to r = 0.85 {teaches with enthusiasm}). Stepwise multiple regression analysis (R2 = 0.76, p < 0.01) identified ratings of the following teaching behaviors as independently significant predictors (p < 0.05) of global ratings of operating room teaching: allows learners to "feel pathology" (B = 0.38), teaches with enthusiasm (B = 0.31), and remains calm and courteous (B = 0.17). CONCLUSIONS: Resident perceptions of operating room teaching by faculty surgeons are strongly associated with overall perceptions of the surgeon and with perceptions of specific teaching behaviors exhibited in the operating room. Regression analysis suggests that approximately 76% of the variability in resident evaluations of operating room teaching may be associated with the extent to which a surgeon demonstrates a positive attitude toward teaching, remains calm and courteous, and provides a "hands on" learning experience. Faculty development efforts aimed at operating room teaching that focus on reinforcing or modifying these behaviors may contribute to improved overall perceptions of faculty by residents.

Reactions of surgical program directors to a web-based interactive educational program focusing on cognitive skills.

OBJECTIVE: To assess reactions by program directors (PDs) to a preview of a scenario from the Fundamentals of Surgery Curriculum (FSC), which is a case-based interactive curriculum developed by the American College of Surgeons's (ACS) Division of Education and designed to be delivered online to first-year (PGY-1) surgical residents. DESIGN: After previewing a scenario, each PD completed a questionnaire requesting age and ratings of comfort using computers, the scenario's utility in addressing 9 educational goals (eg, provides a solid foundation for future learning), and 6 separate features of the scenario (eg, ease of use and feasibility). All ratings were based on a 1-9 scale. For items related to educational goals, ratings were anchored: 1-3 = poor/needs revision; 4-6 = adequate/as good as current methods; 7-9 = excellent/superior to current methods. Informal discussions were also conducted and comments were collected. SETTING: October 2007 ACS Clinical Congress. PARTICIPANTS: In all, 31 PDs participated in the study. RESULTS: Most PDs perceived that the scenario addressed 8 of the 9 educational goals in a manner superior to current methods [eg, provides a solid foundation for future learning (97%), challenges residents (90%), and delivers content consistent with current practices and/or evidence (90%)]. The mean ratings of all scenario features were 7 or greater on the 9-point scale. CONCLUSION: Most PDs reacted very positively to a preview of FSC perceiving that it can address several important educational goals in a manner superior to existing methods. Comments from PDs suggest a high level of interest in incorporating FSC into their residency programs as well as participating in a coordinated multi-institutional evaluation project. The results provide baseline data concerning PD expectations of the utility of FSC that will help to guide and evaluate further developments and applications of this curriculum.

Comparison of resident self-assessments with trained faculty and standardized patient assessments of clinical and technical skills in a structured educational module.

BACKGROUND: This study assessed the reliability of surgical resident self-assessment in comparison with faculty and standardized patient (SP) assessments during a structured educational module focused on perioperative management of a simulated adverse event. METHODS: Seven general surgery residents participated in this module. Residents were assessed during videotaped preoperative and postoperative SP encounters and when dissecting a tumor off of a standardized inanimate vena cava model in a simulated operating room. RESULTS: Preoperative and postoperative assessments by SPs correlated significantly (P < .05) with faculty assessments (r = .75 and r = .79, respectively), but not resident self-assessments. Coefficient alpha was greater than .70 for all assessments except resident preoperative self-assessments. CONCLUSIONS: Faculty and SP assessments can provide reliable data useful for formative feedback. Although resident self-assessment may be useful for the formative assessment of technical skills, results suggest that in the absence of training, residents are not reliable self-assessors of preoperative and postoperative interactions with SPs.

Multi-institutional validation of a web-based core competency assessment system.

OBJECTIVE: The Association of Program Directors in Surgery and the Division of Education of the American College of Surgeons developed and implemented a web-based system for end-of-rotation faculty assessment of ACGME core competencies of residents. This study assesses its reliability and validity across multiple programs. METHODS: Each assessment included ratings (1-5 scale) on 23 items reflecting the 6 core competencies. A total of 4241 end-of-rotation assessments were completed for 332 general surgery residents (> or =5 evaluations each) at 5 sites during the 2004-2005 and 2005-2006 academic years. The mean rating for each resident on each item was computed for each academic year. The mean rating of items representing each competency was computed for each resident. Additional data included USMLE and ABSITE scores, PGY, and status in program (categorical, designated preliminary, and undesignated preliminary). RESULTS: Coefficient alpha was greater than 0.90 for each competency score. Mean ratings for each competency increased significantly (p < 0.01) as a function of PGY. Mean ratings for professionalism and interpersonal/communication skills (IPC) were significantly higher than all other competencies at all PGY levels. Competency ratings of PGY 1 residents correlated significantly with USMLE Step I, ranging from (r = 0.26, p < 0.01) for Professionalism to (r = 0.41, p < 0.001) for Systems-Based Practice. Ratings of Knowledge (r = 0.31, p < 0.01), Practice-Based Learning & Improvement (PBLI; r = 0.22, p < 0.05), and Systems-Based Practice (r = 0.20, p < 0.05) correlated significantly with 2005 ABSITE Total Percentile. Ratings of all competencies correlated significantly with the 2006 ABSITE Total Percentile Score (range: r = 0.20, p < 0.05 for professionalism to r = 0.35, p < 0.001 for knowledge). Categorical and designated preliminary residents received significantly higher ratings (p < 0.05) than nondesignated preliminaries for knowledge, patient care, PBLI, and systems-based practice only. CONCLUSIONS: Faculty ratings of core competencies are internally consistent. The pattern of statistically significant correlations between competency ratings and USMLE and ABSITE scores supports the postdictive and concurrent validity, respectively, of faculty perceptions of resident knowledge. The pattern of increased ratings as a function of PGY supports the construct validity of faculty ratings of resident core competencies.

Validation of a relative head injury severity scale for pediatric trauma.

BACKGROUND: Brain injury is the most important independent predictor of mortality and morbidity in pediatric trauma. The Glasgow Coma Score (GCS) is the commonly used clinical instrument to assess brain injury. However, the GCS or one of its components is often not applicable in children under a certain age or cannot be computed reliably because of the patient's condition or the circumstances surrounding resuscitation efforts. This limits its usefulness in statistical models of trauma outcomes, which rely on complete data collection and entry into trauma registries. This study provides evidence validating use of a relative head injury severity scale (RHISS) derived from available International Classification of Diseases, 9th Revision (ICD-9) diagnosis codes to stratify degree of head injury. METHODS: The patient population was derived from the National Pediatric Trauma Registry (NPTR;1994-2001). Survival Risk Ratios (SRRs) were computed for each head injury ICD-9 code. ICD-9 diagnosis codes related to head injury were then assigned to a RHISS category based on duration of loss of consciousness, location of skull fracture, or both: 0 = none; 1 = mild; 2 = moderate, or 3 = severe head injury. Analysis of variance compared mean SRRs across RHISS categories. Each patient was then assigned to a RHISS category based on their single worst ICD-9 head injury code. Logistic regression analysis was used to predict mortality based on New Injury Severity Score (NISS), whether the patient had been intubated, RHISS, and the Abbreviated Injury Score (AIS) for head and neck injuries. RESULTS: GCS score was missing for 96% of nonsurvivors in the NPTR. Mean SRRs differed significantly (p < 0.001) among ICD-9 codes assigned to each RHISS category, as follows (Mean +/- SD): RHISS (0) = 0.93 +/- 0.16; RHISS (1) = 0.89 +/- 0.22; RHISS (2) = 0.85 +/- 0.26; RHISS (3) = 0.55 +/- 0.35. Logistic regression identified RHISS as an independent significant predictor (p < 0.01) of mortality. CONCLUSION: RHISS is a valid index of degree of head injury in the pediatric trauma population. Unlike GCS, RHISS is more likely to be available in trauma registries, and can be computed from administrative data. RHISS provides a feasible and valid method for quantifying the degree of brain injury in statistical models of pediatric trauma outcome.

Management of adverse surgical events: a structured education module for residents.

BACKGROUND: This pilot project involved the development of a structured, experiential, educational module using a bench model technical skills simulation and standardized patients. It integrated teaching and assessment of clinical, technical, and interpersonal skills, as well as professionalism within the context of an adverse surgical event. METHODS: General surgery residents (postgraduate year [PGY] 2, 3) were asked to participate in the pre-, intra-, and postoperative management of a patient with a retroperitoneal sarcoma. Residents' performances during the module were assessed by standardized patients and faculty, and residents were provided feedback during debriefing sessions. RESULTS: Resident performance during the module was appropriate for the level of training. Residents found this module to be a realistic, challenging, and beneficial learning experience. CONCLUSIONS: Novel educational modules such as this one may serve as a useful addition to resident education in surgery residency programs, particularly in addressing patient safety and the core competencies. Reliability of the model may be enhanced by modifications of the module.

Intubation of pediatric trauma patients in the field: predictor of negative outcome despite risk stratification.

BACKGROUND: Recently, evidence has shown that intubation in the field may not improve or may even adversely affect outcomes. Our objective was to analyze outcomes in pediatric intubated trauma patients using a large national pediatric trauma registry. METHODS: The patient population was derived from the last phase of the National Pediatric Trauma Registry, comprising admissions from 1994 through 2002. Intubated patients were identified, as was their place of intubation: in the field, at a hospital that was not a trauma center, and at a trauma center. Risk stratification was performed for mortality using logistic regression models and variables available at presentation to the emergency room. Odds ratio and variable significance were calculated from the logistic regression model. The percentage of patients discharged to home and an abnormal Functional Independence Measure at hospital discharge examined functional outcome of survivors. RESULTS: There were a total of 50,199 patients, 5460 (11.6%) of whom were intubated (1,930 in the field, 1,654 in the hospital, and 1,876 in a trauma center). Unadjusted mortality rates for intubated patients were as follows: field, 38.5%; hospital, 16.7%; and trauma center, 13.2% (all different, p < 0.05). The developed logistic regression model had an area under the receiver operating characteristic curve of 0.98. Compared with nonintubated patients, the odds ratio for field intubation, for non-trauma center, and for trauma center intubation was 14.4, 5.8, and 4.8, respectively (significantly different field vs. either hospital). The actual (observed) death rate was significantly higher than predicted in those intubated in the field. Stratification of injury by New Injury Severity Score or degree of head injury showed that this difference extended from mild to severe (e.g., odds ratio for New Injury Severity Score < 15 field vs. trauma center intubation, 12.3; odds ratio for none or moderate head injury, 5.1). Similar results were obtained for functional outcome in the survivors. CONCLUSION: Field intubation is an independent strong negative predictor of survival or good functional outcome despite adjustment for severity of injury. Although not causal, the magnitude of these differences should lead to future controlled studies of pediatric trauma field intubations.
