Oncologic Safety of Nipple-Sparing Mastectomy for Breast Cancer in BRCA Gene Mutation Carriers: Outcomes at 70 Months Median Follow-Up.

BACKGROUND: Retention of the nipple-areola complex with nipple-sparing mastectomy (NSM) techniques provides a more natural cosmetic result than procedures that sacrifice the nipple. While the oncologic safety of NSM is established by several studies, there is little long-term data on outcomes in BRCA mutation carriers with breast cancer. PATIENTS AND METHODS: BRCA1/2 mutation carriers who underwent NSM and immediate reconstruction from 2008 to 2019 were reviewed and patients with breast cancer on biopsy or final pathology were included. Patient demographics and tumor characteristics, as well as treatment, recurrence, and survival data were collected. RESULTS: A total of 114 therapeutic NSM were performed in 105 BRCA mutation carriers (56 BRCA1, 47 BRCA2, and two women with both mutations). Median age was 45 years. Cancers were 18% stage 0, 52% stage I, 27% stage II, and 3% stage III. Mean invasive tumor size was 1.6 cm and 33 (35%) invasive tumors were triple negative. There were five (4.4%) positive nipple margins on final pathology; all underwent nipple excision. Most patients (80, 76%) received systemic therapy: 65 (62%) received chemotherapy and 48 (46%) received endocrine therapy. At 70 months median follow-up (range 15-150 months), no patient had developed a recurrence in the retained nipple-areola complex or at the site of a nipple excised for a positive margin. The rate of locoregional recurrence outside the nipple was 2.6%, and the rate of distant recurrence was 3.8%. Overall survival was 96%. CONCLUSIONS: NSM is a safe option for BRCA1 and BRCA2 mutation carriers who undergo mastectomy for breast cancer.

How Protective are Nipple-Sparing Prophylactic Mastectomies in BRCA1 and BRCA2 Mutation Carriers?

BACKGROUND: Nipple-sparing mastectomy (NSM) is now routinely offered to BRCA mutation carriers for risk reduction. We assessed the rates of ipsilateral cancer events after prophylactic and therapeutic NSM in BRCA1 and BRCA2 mutation carriers. METHODS: BRCA1 and BRCA2 mutation carriers undergoing NSM from October 2007 to June 2019 were identified in a single-institution prospective database, with variants of unknown significance being excluded. Patient, tumor, and outcomes data were collected. Follow-up analysis was by cumulative breast-years (total years of follow-up of each breast) and woman-years (total years of follow-up of each woman). RESULTS: Overall, 307 BRCA1 and BRCA2 mutation carriers (160 BRCA1, mean age 41.4 years [range 21-65]; and 147 BRCA2, mean age 43.8 years [range 23-65]) underwent 607 NSMs, with a median follow-up of 42 months (range 1-143). 388 bilateral prophylactic NSMs had 744 cumulative woman-years of follow-up, with no new cancers seen (< 0.0013 new cancers per woman-years); 251 BRCA1 prophylactic NSMs had 1034 cumulative breast-years of follow-up, with no new ipsilateral cancers seen (< 0.0010 per breast-year); 66 BRCA1 therapeutic NSMs had 328 cumulative breast-years of follow-up, with one ipsilateral cancer recurrence not directly involving the nipple or areola (0.0030 per breast-year); 237 BRCA2 prophylactic NSMs had 926 cumulative breast-years of follow-up, with no new ipsilateral cancers seen (< 0.0011 per breast-year); and 53 BRCA2 therapeutic NSMs had 239 cumulative breast-years of follow-up, with two ipsilateral recurrent cancers, neither of which directly involved the nipple or areola (0.0084 per breast-year). CONCLUSIONS: The risk of new ipsilateral breast cancers is extremely low after NSM in BRCA1 and BRCA2 mutation carriers. NSM is an effective risk-reducing strategy for BRCA gene mutations.

Robotic-assisted parathyroidectomy via transaxillary approach: feasibility and learning curves.

BACKGROUND: There have been few reports of robotic-assisted transaxillary parathyroidectomy in the literature. We aim to report our experience with robotic-assisted transaxillary parathyroidectomy for primary hyperparathyroidism (PHPT) in the Western population. METHODS: A retrospective study was performed from July 2010 through July 2019 at two institutions, one in the United States and one in France. Demographic characteristics and perioperative data were collected for all patients undergoing robotic-assisted transaxillary parathyroidectomy by a single surgeon at each institution. A linear regression model was developed to describe the learning curve for this procedure at each institution. RESULTS: One-hundred and two patients with PHPT were included with a median age of 55.6±12.4 years and median body mass index (BMI) of 25.5±6.1 kg/m2. The majority of patients were female (80.4%). Median total operative time was 116±53 minutes. Minor complications were reported in 2 patients (1.96%), and one case was converted to a trans-cervical approach (TCA) for four-gland exploration. Median patient follow-up time was 6.5±12.2 months, and disease recurrence was reported in one patient. Calculated learning curves showed that one surgeon achieved proficiency by the eighth case, and the other achieved proficiency by the fourteenth case. CONCLUSIONS: This is the largest reported experience of robotic-assisted transaxillary parathyroidectomy for PHPT in the Asian and Western population. Analysis of the procedural learning curve demonstrates that proficiency in this technique was achieved after performance of less than 15 surgeries. This procedure is safe and feasible in the hands of experienced surgeons for select patients with localized disease.

Does Distance to Treatment Affect Mortality Rate for Surgical Oncology Patients?

INTRODUCTION: Using the National Cancer Database (NCDB), we seek to analyze the relationship of patient distance to hospital of treatment on mortality trends after surgery, since patients often travel large distances to referral centers. METHODS: A retrospective cohort study of the NCDB from 2004 to 2013 was performed, and patients with gastrointestinal, melanoma, and head and neck primary site tumors who underwent surgery were included. We excluded cases with no recorded mortality status or distance from the hospital. A multivariable logistic regression was conducted with adjustments for population density, treating facility location, age, race, gender, education, income, insurance, comorbidities (Charlson-Deyo score), days from diagnosis to treatment, positive margin, tumor stage and grade, and lymph or vascular invasion. RESULTS: A total of 1 424 482 patients were included. Overall median distance to hospital was 9.7 miles (range 4.2-23.7 miles); 696 647 (48.91%) of the sample traveled a distance greater than 10 miles to the institution where the procedure was performed. The multivariable regression analysis demonstrated overall lower mortality for those patients travelling a longer distance to care for multiple tumor types, including: liver (OR .87, .77-.99, P = .032), pancreas (OR .82, .76-.89, P < .001), colon (OR .92, .89-.95, P < .001), rectum (OR .90, .83-.96, P = .003), melanoma (OR .83, .79-.88, P < .001), and tumors of the larynx (OR .80, .69-.94, P = .005). DISCUSSION: Increased distance traveled for surgical treatment has a significant correlation with decreased odds of mortality for multiple cancers, highlighting the importance of centralized referral patterns for oncology care.

Gender disparities are present in academic rank and leadership positions despite overall equivalence in research productivity indices among senior members of American Head and Neck Society (AHNS) Fellowship Faculty.

BACKGROUND: This study aims to examine potential disparities in scholarly performance based on sex, academic rank, leadership positions, and regional distribution of faculty in accredited Head and Neck Surgery fellowships in the United States. METHODS: Online faculty listings for 37 accredited fellowships were organized according to academic rank, leadership position, sex, and institutional location. Academic productivity was measured with three bibliometric indices: h-index, m-index, and the weighted relative citation ratio. RESULTS: A total of 732 faculty members were included, of which 153 (21%) were female. Fifty-eight males (89.2%) held leadership positions, compared to seven females (10.8%). There was no significant difference in overall productivity between male and female senior faculty. There were regional differences in productivity by sex. CONCLUSIONS: Females are underrepresented in senior faculty and within three common leadership positions, although scholarly productivity for male and female senior faculty and for those in leadership positions is similar.

Conventional Robotic Endoscopic Thyroidectomy for Thyroid Cancer.

The conventional robotic endoscopic remote access techniques detailed in this article have been discussed in a series of increasing volumes in the literature, including for the treatment of thyroid cancer. Lower-volume centers now perform most robotic thyroidectomies in the United States and are responsible for recent increases in utilization patterns despite higher complication rates. These trends highlight the importance of increasing surgeon exposure to and experience with these techniques in order to improve procedure safety. Additional large-volume, multicenter studies to define patients who will most benefit from these conventional robotic endoscopic procedures for thyroid cancer are needed.

Effect of Community and Academic Surgical Rotation Sites on Medical Student Performance Outcomes and Career Choices.

OBJECTIVE: We hypothesize that students exposed to both academic and community surgery clerkship sites will have higher National Board of Medical Examiners Subject Exam in Surgery (NBME SES) scores and be more likely to pursue a career in a surgical specialty. DESIGN: The NBME surgery subject exam scores and National Resident Matching Program (NRMP) results were collected for all medical students rotating through the surgery clerkship over 4 years. Permutations of sites were analyzed against exam scores and match rates into surgical and nonsurgical specialties. SETTING: This study was performed at the Tulane University School of Medicine, in New Orleans, Louisiana, United States of America. PARTICIPANTS: Data for a total of 910 students rotating through the surgery clerkship over a period of 4 years was collected and analyzed. RESULTS: There was no statistical difference in NBME subject exam scores (p = 0.44) or match rates into a surgical specialty (p = 0.13) as stratified by site placement. Average NBME surgery subject exam scores were higher for those pursuing a surgical specialty (p < 0.001). CONCLUSIONS: The combination of sites experienced during the surgery clerkship did not affect NBME surgery subject exam scores nor lead to a tendency to match into a surgical specialty.

Somatosensory evoked potential: Preventing brachial plexus injury in transaxillary robotic surgery.

OBJECTIVES/HYPOTHESIS: The potential for brachial plexopathy due to arm positioning is a major concern regarding the robotic transaxillary approach. Intraoperative nerve monitoring via somatosensory evoked potential (SSEP) has been suggested to prevent such injury. In this study, we examined the use of SSEP in detecting imminent brachial plexus traction during robotic transaxillary thyroid and parathyroid surgery. STUDY DESIGN: Retrospective case series. METHODS: A analysis was performed for all patients undergoing robotic transaxillary surgery with continuous intraoperative SSEP monitoring at a North American institution between 2015 and 2017. A significant intraoperative SSEP change was defined as a decrease in signal amplitude of >50% or an increase in latency of >10% from baseline established during preoperative positioning. RESULTS: One hundred thirty-seven robotic transaxillary surgeries using SSEP monitoring were performed on 123 patients. Seven patients (5.1%) developed significant changes, with an average SSEP amplitude reduction of 73% ± 12% recorded at the signals' nadir. Immediate arm repositioning resulted in recovery of signals and complete return to baseline parameters in 14.3 ± 9.2 minutes. There was no difference in age (40.4 ± 9.4 years vs. 44.5 ± 13.4 years; P = .31) or body mass index (27.3 ± 3.7 kg/m2 vs. 26.9 ± 6.1 kg/m2 ; P = .79) between cases with and without SSEP change. Operative time was shorter for patients with significant SSEP change (131.6 ± 14.7 minutes vs. 146.5 ± 46.7 minutes; P = .048). There were no postoperative positional brachial plexus injuries. CONCLUSIONS: SSEP is a novel, safe, and reliable tool in detection of position-related brachial plexus neuropathy. Intraoperative monitoring using SSEP can play a vital role in early recognition and prevention of injury during robotic transaxillary thyroid and parathyroid surgery. LEVEL OF EVIDENCE: 4 Laryngoscope, 129:2663-2668, 2019.

Thyroid surgery and obesity: Cohort study of surgical outcomes and local specific complications.

INTRODUCTION: Obesity is associated with numerous complications after elective general surgeries. The aim is to compare surgical outcomes and local specific complications in obese and non-obese patients after thyroid surgery. METHODS: Retrospective study over a 3-year period at a North American academic institution. Outcome measures were operative time, estimated blood loss, hospital length of stay, and local specific complications (hypocalcemia, recurrent laryngeal nerve injury, wound hematoma, wound seroma, and chyle leakage). RESULTS: A total of 469 patients were included (mean [SD] age, 50.11 [15.01] years; mean [SD] BMI, 30.5 [8.3] kg/m2; 207 [44.14%] obese). There was no difference in operative time (125.7 vs. 129.6, p = 0.52), estimated blood loss (16.88 vs. 14.56, p = 0.28), or hospital length of stay (0.95 vs. 0.95, p = 0.96). Overall, there was no difference in the rates of local specific complications between the two groups. CONCLUSIONS: Obesity is not associated with adverse outcomes in patients undergoing thyroid surgery.

Remote-Access Thyroidectomy: A Multi-Institutional North American Experience with Transaxillary, Robotic Facelift, and Transoral Endoscopic Vestibular Approaches.

BACKGROUND: Many remote-access approaches (RAAs) to the thyroid have been described to circumvent anterior neck scarring, including the transaxillary, robotic facelift, and transoral endoscopic vestibular approaches. These techniques have been popularized in Asia, but adoption has been slow in North America. We aimed to examine multi-institutional North American outcomes with RAA thyroidectomy in the context of these institutions' transcervical approach (TCA) outcomes. STUDY DESIGN: Cases of lobectomy and total thyroidectomy via transaxillary, robotic facelift, and transoral endoscopic vestibular approaches were reviewed. Demographic characteristics, outcomes, and complications were compared with the same measures in patients undergoing lobectomy and total thyroidectomy via TCA by the primary RAA surgeons at each institution. Patients who underwent parathyroidectomy or other concomitant neck dissection procedures were excluded. RESULTS: Two hundred and sixteen RAA thyroidectomies were attempted (92 transoral endoscopic vestibular approaches, 70 transaxillary, and 54 robotic facelift) and 410 TCA thyroidectomies were performed. There was no difference in mean index nodule sizes between RAA (2.8 ± 1.6 cm) and TCA (2.9 ± 1.9 cm) cohorts (p = 0.72). Median operative times for lobectomy were 146 minutes (range 60 to 343 minutes) and 90 minutes (range 25 to 247 minutes) for the RAA and TCA cohorts, respectively (p < 0.0001). Median operative time for total thyroidectomy was 170 minutes (range 100 to 398 minutes) vs 126.5 minutes (range 51 to 260 minutes) for the RAA and TCA cohorts, respectively (p < 0.0001). There was no difference in the rates of permanent recurrent laryngeal nerve injury between the RAA (0 of 216 [0%]) and TCA (0 of 410 [0%]) cohorts (p = 0.99). CONCLUSIONS: Remote-access approach thyroidectomy can be performed in a select North American patient population with outcomes comparable with TCA.

The Sunshine Act and Surgeons: A Nation-Wide Analysis of Industry Payments to Physicians.

BACKGROUND: The Physician Payments Sunshine Act mandates the submission of payment records between medical providers and industry. We used the Open Payments Program database to compare industry payments to surgeons and nonsurgeons, as well as among surgical specialties, and to identify geographic distribution of payments. MATERIALS AND METHODS: We included all reported industry payments in the Centers for Medicare and Medicaid Services' Open Payments Program in the United States, 2014-2015. Multivariable regression fixed effects panel analysis of total payments was conducted among surgeons, adjusting for surgeon specialty, payor type, payment category, and state. A geographic heat map was created. RESULTS: Of 2,097,150 subjects meeting criteria, 1,957,528 (45.66%) were physicians. The mean standard deviation (SD) payment overall was $232.64 ($6262.00), and the state with the highest mean (SD) payment was Vermont at $2691.61 ($11,508.40). Surgeons numbered 153,916 (7.86%). The specialty with the highest mean (SD) payment was orthopedic surgery at $2811.50 ($33,632.71, P < 0.001). Among 2,097,150 subjects meeting criteria, in multivariable regression fixed effects panel analysis, orthopedic compared to general surgeons were significantly likely to receive more industry payments (beta $1065.34 [95% CI $279.00-1851.00, P = 0.008), even controlling for payor, payment type, and state. Significant geographic disparities in payment were noted as 12 states received the top mean ($24.52-$500,000.00), leaving seven states with the lowest ($0.00-$12.56). CONCLUSIONS: There are significant differences in industry payments to surgeons versus nonsurgeons and among surgical specialties, as well geographic distribution of payments. These data may prompt further investigation into trends and their causality and effects on research and practice.

Robotic Neck Surgery in the Pediatric Population.

INTRODUCTION: Thyroid, parathyroid, and thymus surgeries are traditionally performed via a cervical approach. However, robot-assisted procedures can provide a safe alternative for neck surgeries. We report our experiences with robotic transaxillary and retroauricular approaches in pediatric patients. CASE PRESENTATION: We conducted a retrospective review of pediatric patients who underwent robot-assisted neck surgery by a single surgeon between April 2010 and May 2017. Patient demographics and surgical outcomes including operative time, incidence of complications, and length of hospital stay were evaluated. MANAGEMENT AND OUTCOMES: Nine surgeries in 7 female patients were reviewed (mean age, 16.0 ± 1.58 years; mean body mass index, 22.5 ± 0.75). Two thyroid lobectomies, 2 complete thyroidectomies, 1 subtotal thyroidectomy, 1 thyroid lobectomy with thymectomy, 2 subtotal parathyroidectomies with thymectomy, and 1 dermoid cyst excision were performed. Two surgeries with the retroauricular approach had a mean surgical time of 142.0 ± 6.13 minutes. Seven surgeries with the transaxillary approach had a mean surgical time of 146.1 ± 21.01 minutes. There were no reported conversions, permanent vocal cord paralysis, permanent hypoparathyroidism, hematoma, or seroma. There was 1 case (11%) of temporary shoulder hypoesthesia and 2 cases of temporary vocal cord paresis (22%). DISCUSSION: This series on robot-assisted neck surgeries in children describes procedures performed with robotic transaxillary and retroauricular approaches. In the hands of a high-volume surgeon the techniques are feasible and safe options for operations in the neck in a select group of pediatric patients.

Surgery for Graves' disease in the era of robotic-assisted surgery: a study of safety and feasibility in the Western population.

PURPOSE: Thyroid surgery for Graves' disease is known to be associated with higher risk of complications. We seek to compare outcomes between robotic-assisted and open cervical approach thyroid surgery in patients with Graves' disease in the Western population. METHODS: We performed a retrospective cohort study using prospectively collected databases for patients undergoing robotic-assisted or conventional cervical approach thyroid surgery for Graves' disease at two academic medical centers, one in North America (New Orleans, LA) and one in Europe (Paris, France). RESULTS: A total of 102 patients were included, of which 56 (55%) underwent robotic thyroidectomy and 46 (45%) underwent conventional open cervical thyroidectomy. Mean age was 40.2 ± 13.2 years and 94 (92%) were females. Mean BMI for the sample was 27.7 ± 10.2 kg/m2. There was a trend towards larger specimen volume in the robotic-assisted group, 84.9 ± 62.2 cm3 versus 65.2 ± 40.5 cm3 (p = 0.07). Mean length of stay for the French patients undergoing robotic-assisted surgery was 3.2 ± 0.5 days. For the American cohort, length of stay was significantly shorter for robotic-assisted thyroidectomy, at 0.8 ± 0.4 days versus 1.0 ± 0.2 days (p = 0.003). Operative time was longer in patients who underwent robotic thyroidectomy (174.4 ± 33.5 min) compared to patients who underwent traditional cervical approach (121.2 ± 41.1 min, p < 0.0001). There was no difference in complication rates for the overall sample of patients undergoing robotic-assisted or open cervical procedures. CONCLUSION: Robotic thyroid surgery is safe in a select group of patients with Graves' disease in the Western population. Additional studies are warranted to further investigate these findings.

Post-Operative Infections: Trends in Distribution, Risk Factors, and Clinical and Economic Burdens.

BACKGROUND: Post-operative infection (POI) is a serious complication in all surgical disciplines and can derail a patient's treatment and recovery course. In this analysis, we examine national trends, risk factors, and costs associated with POI. METHODS: Using the Nationwide Inpatient Sample (NIS) for the years available for data analysis at the time of this study (2003-2010), we performed a cross-sectional study of adult (≥18 years) inpatients with POI and designated Clinical Classification Software (CCS) procedural class codes for the operations performed. A comparison group was selected randomly from patients with the same CCS codes who underwent the same procedures but did not experience POI. As the NIS represents 20% of U.S. hospital admissions, excess cost and stay were calculated on the basis of the average difference between cost and duration of stay for POI cases and the cost and duration of stay for the comparison group, then extrapolated to estimate the national burden for the remaining 80% of stays nationwide. RESULTS: Sample admissions included 139,652 cases of POI and 941,670 comparison subjects. The POIs were most common in procedures involving the digestive tract (46.5%), cardiovascular system (16.3%), or musculoskeletal system (11.2%). Older age, male gender, high Charlson Comorbidity Index Score (CCIS), and teaching, urban, or large hospitals were independent risk factors for POI in the multivariable model (p < 0.05). A POI was associated with a higher risk of death (odds ratio 2.93; 95% confidence interval 2.82-3.04, p < 0.001). Nationally, we estimate that POI resulted in an annual average of 1.04 million days of excess hospital stay and $2.72 billion excess cost. CONCLUSIONS: Identification of independent risk factors suggests areas for quality improvement initiatives. Post-operative infection carries substantial clinical and financial burdens in the United States, and further analysis of the associated costs is needed to identify areas for intervention to reduce this burden.

Well-differentiated thyroid cancer and robotic transaxillary surgery at a North American institution.

BACKGROUND: Recent studies from Asia have reported the safety and feasibility of robotic-assisted thyroid surgery. In the United States, several small series and case reports have been published, mostly regarding treatment of benign disease. The aim of our study is to report the safety and feasibility of robotic surgery for well-differentiated thyroid cancer patients at a North American institution. MATERIALS AND METHODS: We performed a retrospective cohort study using a prospectively collected single-center clinical database at Tulane University Medical Center. We included all well-differentiated thyroid cancer patients who underwent robotic-assisted or conventional cervical approach thyroid surgery with or without lymph node dissections at our institution from January 2015 to June 2017. Patient demographics and perioperative data were collected and analyzed. RESULTS: A total of 144 surgeries for thyroid cancer were performed; 35 (24.3%) were robotic-assisted. There were no significant differences in estimated blood loss, operative times, complication rates, specimen sizes, positive microscopic margins, number of lymph nodes removed with associated lymph node dissections, patient follow-up duration, or clinical recurrence rates between the two groups. Overall length of stay was shorter for robotic-assisted surgery, at 0.6 ± 0.9 d, versus 1.1 ± 1.2 d for conventional open surgery (P = 0.009). For robotic-assisted surgery, 19 patients (54.3%) were discharged on the day of procedure, and only one patient was admitted as inpatient to the hospital (2.9%). CONCLUSIONS: Robot-assisted thyroid surgery is a safe, feasible, and oncologically sound approach for a select group of well-differentiated thyroid cancer patients. However, long-term studies are needed.

Effectiveness of systems changes suggested by simulation of adverse surgical outcomes.

Background: Simulation of adverse outcomes (SAO) has been described as a technique to improve effectiveness of root cause analysis (RCA) in healthcare. We hypothesise that SAO can effectively identify unsuspected root causes amenable to systems changes. Methods: Systems changes were developed and tested for effectiveness in a modified simulation, which was performed eight times, recorded and analysed. Results: In seven of eight simulations, systems changes were effectively utilised by participants, who contacted anaesthesia using the number list and telephone provided to express concern. In six of seven simulations where anaesthesia was contacted, they provided care that avoided the adverse event. In two simulations, the adverse event transpired despite implemented systems changes, but for different reasons than originally identified. In one case, appropriate personnel were contacted but did not provide the direction necessary to avoid the adverse event, and in one case, the telephone malfunctioned. Conclusions: Systems changes suggested by SAO can effectively correct deficiencies and help improve outcomes, although adverse events can occur despite implementation. Further study of systems concepts may provide suggestions for changes that function more reliably in complex healthcare systems. The information gathered from these simulations can be used to identify potential deficiencies, prevent future errors and improve patient safety.

Using simulation to improve root cause analysis of adverse surgical outcomes.

OBJECTIVE: The purpose of this study was to develop and test a simulation method of conducting investigation of the causality of adverse surgical outcomes. DESIGN: Six hundred and thirty-one closed claims of a major medical malpractice insurance company were reviewed. Each case had undergone conventional root cause analysis (RCA). Claims were categorized by comparing the predominant underlying cause documented in the case files. Three cases were selected for simulation. SETTING: All records (medical and legal) were analyzed. Simulation scenarios were developed by abstracting data from the records and then developing paper and electronic medical records, choosing appropriate STUDY PARTICIPANTS: including test subjects and confederates, scripting the simulation and choosing the appropriate simulated environment. INTERVENTION: In a simulation center, each case simulation was run 6-7 times and recorded, with participants debriefed at the conclusion. MAIN OUTCOME MEASURES: Sources of error identified during simulation were compared with those noted in the closed claims. Test subject decision-making was assessed qualitatively. RESULTS: Simulation of adverse outcomes (SAOs) identified more system errors and revealed the way complex decisions were made by test subjects. Compared with conventional RCA, SAO identified root causes less focused on errors by individuals and more on systems-based error. CONCLUSIONS: The use of simulation for investigation of adverse surgical outcomes is feasible and identifies causes that may be more amenable to effective systems changes than conventional RCA. The information that SAO provides may facilitate the implementation of corrective measures, decreasing the risk of recurrence and improving patient safety.

Integrated models of education and service involving community-based health care for underserved populations: Tulane student-run free clinics.

OBJECTIVES: Throughout the United States numerous models of local programs, including student-run clinics, exist to address the issue of access to care. The role of these clinics in serving the local community and contributing to medical education has been documented only in limited detail, however. The purpose of this article is to describe the clinic models, patient demographics, and services provided by four student-run clinics in New Orleans. METHODS: This is a retrospective, multisite chart review study of adult patients examined at student-run clinics between January 1, 2010 and July 31, 2011. RESULTS: During a 19-month period, 859 patients collectively were seen at the clinics, for a total of 1455 visits. The most common reasons for seeking care were medication refills (21.6%) and musculoskeletal pain (12.0%). Counseling and health education were provided primarily for smoking cessation (9.0%), diabetes management (7.1%), and hypertension management (5.8%). Nearly one-fifth of patients were given a referral to primary care services. In the 2010-2011 academic year, 87.6% of preclinical medical students volunteered at ≥1 of these clinics and spent 4508 hours during 1478 shifts. CONCLUSIONS: This article highlights the role of student-run clinics in the community, the safety-net healthcare system, and medical education. Future directions include the establishment of a new clinic, fundraising, and prospective studies to further assess the impact of student-run clinics.
