Identification of Leadership Behaviors that Impact General Surgery Junior Residents' Well-being: A Needs Assessment in a Single Academic Center.

OBJECTIVE: Emerging literature has started to link leadership with the well-being of team members; however, this link during residency training has not been studied. The objective of this study was to perform a needs assessment to identify leadership behaviors among senior residents and evaluate the impact that these behaviors have on junior residents' well-being. DESIGN: A semi-structured question script was developed and ∼60 minute virtual focus groups were held during protected educational time, until data saturation was reached. Data analysis was performed in the tradition of grounded theory. SETTING: This study was performed at Oregon Health & Science University, one of the largest general surgery programs. PARTICIPANTS: Participants enrolled in the general surgery residency program from July 2020 to February 2021 were included. 35 general surgery residents participated in the focus groups. RESULTS: Two major themes resulted from the data analysis: (1) Effective leadership behaviors and their positive consequences, and (2) Ineffective leadership behaviors and their negative consequences. Effective and ineffective leadership were characterized by the presence or absence of 6 main behaviors: supportive and empowering, team building, management skills, emotional intelligence, effective communication, and teaching. Effective and ineffective leadership positively and negatively impacted residents' well-being, individual growth, and psychological safety. CONCLUSIONS: The results from this study identified leadership behaviors from senior residents and demonstrated that those behaviors have a significant short-term and long-term positive and negative impact on junior residents' well-being. These results fill a gap in the literature, and can serve as a guide for surgical educators to develop evidence-based leadership curricula.

Career Advancement for Surgeon-Educators:Findings from a Modified Delphi Process.

OBJECTIVES: Reward and recognition of surgical education as an academic activity remains a highly variable process between institutions. The goal of this study is to provide expert consensus definition of an academic surgical educator, with focus on criteria for academic promotion. STUDY DESIGN AND SETTING: Following IRB approval, a Web-based modified Delphi process was used to generate prioritized academic promotion criteria for surgical educators. PARTICIPANTS AND SETTING: Participants were recruited nationally from a pool of senior academic surgeons who are members of the Society of University Surgeons and the Society of Surgical Chairs. RESULTS: Following a three-round modified Delphi process, the top domains of educational activity for promotion to associate professor and professor were scholarship, teaching, and administration; mentorship was also a priority category for promotion to professor. The top three activities described for promotion to Associate Professor were active participation in conferences/ departmental educational activities for medical students and residents; educational portfolio demonstrating commitment to activities as an educator; and clinical teaching excellence at their home institution. The three activities most highly scored items for promotion to Professor were mentorship of junior surgical educators; active participation in conferences/ departmental educational activities for medical students and residents; and a record of teaching excellence at the medical student and resident levels. CONCLUSIONS: These findings demonstrate a progression from teacher to scholar to leader across a surgical educator's career, with each level incorporating and building upon the prior activities. Identification of categories and criteria may meaningfully inform best practices to be incorporated into the career development and promotion processes for surgeons on an educator academic pathway.

Unifying the Hepatopancreatobiliary Surgery Fellowship Curriculum via Delphi Consensus.

BACKGROUND: Hepatopancreatobiliary (HPB) Fellowship training in the Americas consists of 3 distinctive routes with variable curricula: Surgical Oncology Fellowship via the Society of Surgical Oncology (SSO), Abdominal Transplant Surgery Fellowship via the American Society of Transplant Surgeons (ASTS), and HPB Fellowship via the Americas Hepato-Pancreato-Biliary Association (AHPBA). Our objective was to establish a pan-American consensus among HPB surgeons, surgical oncologists, abdominal transplant surgeons, and general surgery residency program directors (GSPDs) on a core knowledge curriculum for HPB fellowship, and to identify topics appropriate for general surgery residency and subspecialty beyond HPB fellowship. STUDY DESIGN: A 3-round modified Delphi process was used. Baseline statements were developed by the Education and Training Committee of the AHPBA, in collaboration with representatives of the SSO, ASTS, and GSPDs. The expert panel, consisting of members of the 3 societies together with GSPDs, rated the statements on a 5-point Likert scale and suggested editing or adding new statements. A statement was included in the final curriculum when Cronbach's alpha value was ≥ 0.8 and ≥ 80% of the panel agreed on inclusion. RESULTS: The response rate was 100% for the first round, and 98% for the second and third rounds. Eighty-nine of 138 proposed statements were included in the final HPB fellowship curriculum. Curricula for general surgery residency and subspecialty beyond HPB fellowship included 50 and 29 statements, respectively. CONCLUSIONS: A multinational consensus on core knowledge for an HPB fellowship curriculum was achieved via the modified Delphi method. This core curriculum may be used to standardize HPB fellowship training across different pathways in the Americas.

Association Between Medicaid Expansion and the Use of Outpatient General Surgical Care Among US Adults in Multiple States.

Importance: The Affordable Care Act expanded access to Medicaid coverage in 2014 for individuals living in participating states. Whether expanded coverage was associated with increases in the use of outpatient surgical care, particularly among underserved populations, remains unknown. Objective: To evaluate the association between state participation in the Affordable Care Act Medicaid expansion reform and the use of outpatient surgical care. Design, Setting, and Participants: This case-control study used a quasi-experimental difference-in-differences design to compare the use of outpatient surgical care at the facility and state levels by patient demographic characteristics and payer categories (Medicaid, private insurance, and no insurance). Data from 2013 (before Medicaid expansion reform) and 2015 (after Medicaid expansion reform) were obtained from the State Ambulatory Surgery and Services Database of the Healthcare Cost and Utilization Project. The absolute and mean numbers of procedures performed at outpatient surgical centers in 2 states (Michigan and New York) that participated in Medicaid expansion (expansion states) were compared with those performed at outpatient surgical centers in 2 states (Florida and North Carolina) that did not participate in Medicaid expansion (nonexpansion states). The population-based sample included 207 176 patients aged 18 to 64 years who received 4 common outpatient procedures (laparoscopic cholecystectomy, breast lumpectomy, open inguinal hernia repair, and laparoscopic inguinal hernia repair). Data were analyzed from May 19 to August 25, 2019. Interventions: State variation in the adoption of Medicaid expansion before and after expansion reform was implemented through the Affordable Care Act. Main Outcomes and Measures: Changes in the mean number of procedures performed at the facility level before and after Medicaid expansion reform in states with and without expanded Medicaid coverage. Results: A total of 207 176 patients (106 395 women [51.35%] and 100 781 men [48.65%]; mean [SD] age, 45.7 [12.4] years) were included in the sample. Overall, 116 752 procedures were performed in Medicaid expansion states and 90 424 procedures in nonexpansion states. A 9.8% increase (95% CI, 0.4%-20.0%; P = .04) in cholecystectomies, a 26.1% increase (95% CI, 9.8%-44.7%; P = .001) in lumpectomies, and a 16.3% increase (95% CI, 2.9%-31.5%; P = .02) in laparoscopic inguinal hernia repairs were observed at the facility level in expansion states compared with nonexpansion states. Among patients with Medicaid coverage, the mean number of procedures performed in all 4 procedure categories increased between 60.5% (95% CI, 24.7%-106.6%; P < .001) and 79.2% (95% CI, 53.5%-109.2%; P < .001) at the facility level. The increases in the number of Medicaid patients who received treatment exceeded the reductions in the number of uninsured patients who received treatment with laparoscopic cholecystectomy, open inguinal hernia repair, and laparoscopic inguinal hernia repairs in expansion states compared with nonexpansion states. Black patients received more laparoscopic cholecystectomies, lumpectomies, and open inguinal hernia repairs in expansion states than in nonexpansion states. Conclusions and Relevance: Study results suggest that Medicaid expansion was associated with increases in the use of outpatient surgical care in states that participated in Medicaid expansion. Most of this increase represented patients who were newly treated rather than patients who converted from no insurance to Medicaid coverage.

Development of an Assessment Tool for Surgeons in Their First Year of Independent Practice: The Junior Surgeon Performance Assessment Tool.

OBJECTIVE: The purpose of this study was to create an assessment tool to evaluate newly practicing surgeons. DESIGN: In this prospective mixed methods study, a needs assessment was performed by conducting focus groups with practicing general surgeons, asking questions regarding essential surgeon qualities, behaviors observed in inexperienced surgeons, current assessment methods, and desired assessment tool elements and attributes. A qualitative analysis was performed using a grounded theory methodology. The Junior Surgeon Performance Assessment Tool (JSPAT) was created using a 4-point scale for each category developed, with themes identified in the qualitative analysis used to create behavioral anchors. The JSPAT was evaluated by focus group participants and by members of the American College of Surgeons Advisory Council for Rural Surgery using an online survey. SETTING: Rural and nonuniversity-based hospitals throughout the state of Oregon. PARTICIPANTS: Practicing general surgeons. RESULTS: Focus groups consisted of 31 surgeons (mean age 49, mean experience 17 years) from 11 different hospitals. Qualitative analysis revealed 91 different themes, which were grouped into 5 domains (technical skills, interaction with patients, interaction with surgeon colleagues, interactions with the greater medical community, and self-care) to create the assessment tool. Twenty online survey responses providing feedback on the assessment tool were obtained, with 75% rating the JSPAT useful or very useful and 69% satisfied or very satisfied with the time to complete the tool. CONCLUSIONS: A mixed-methods model was used to create an assessment tool for surgeons in their first year of independent practice. Survey data demonstrated that practicing surgeons find value in the JSPAT.

Surgical palliative care training in general surgery residency: An educational needs assessment.

INTRODUCTION: There is increasing recognition that Surgical Palliative Care is an essential component of the holistic care of surgical patients and involves more than end-of-life care in the intensive care unit. General surgery residents are clinically exposed to patients with palliative care needs during each year of training, but few have a dedicated surgical palliative care curriculum. We undertook this educational needs assessment as the first step towards a longitudinal curriculum. METHODS: We conducted an anonymous survey of 94 general surgery residents and 115 faculty at community and university hospitals to assess their experience and comfort with surgical palliative care delivery. Residents and faculty were asked multiple choice and open-ended questions. RESULTS: There was a 55% response rate from residents and 33% response rate from faculty. The majority (77%) of respondents were junior residents (PGY1-3) and university-based faculty (66%). Approximately half of residents felt comfortable leading conversations in goals of care (58%), comfort-focused care (52%) and delivering bad news (57%), while greater than 90% of faculty agreed that chief residents needed additional training. All residents agreed they needed additional training and 85% wanted a formal curriculum. Analysis of open-ended questions suggests a deficiency in the pre-operative setting as no residents had participated in these conversations in an outpatient setting. CONCLUSION: Residents and faculty believe trainees would benefit from further education in surgical palliative care with a dedicated curriculum. The outpatient, pre-operative counseling of patients was identified as a key learning need. These data support our ongoing work to develop a surgically pertinent palliative care curriculum.

Analysis of Gender-based Differences in Surgery Faculty Compensation, Promotion, and Retention: Establishing Equity.

OBJECTIVES: The objectives of this study were to evaluate gender-based differences in faculty salaries before and after implementation of a university-wide objective compensation plan, Faculty First (FF), in alignment with Association of American Medical Colleges regional median salary (AAMC-WRMS). Gender-based differences in promotion and retention were also assessed. SUMMARY BACKGROUND DATA: Previous studies demonstrate that female faculty within surgery are compensated less than male counterparts are and have decreased representation in higher academic ranks and leadership positions. METHODS: At a single institution, surgery faculty salaries and work relative value units (wRVUs) were reviewed from 2009 to 2017, and time to promotion and retention were reviewed from 1998 to 2007. In 2015, FF supplanted specialty-specific compensation plans. Salaries and wRVUs relative to AAMC-WRMS, time to promotion, and retention were compared between genders. RESULTS: Female faculty (N = 24) were compensated significantly less than males were (N = 62) before FF (P = 0.004). Female faculty compensation significantly increased after FF (P < 0.001). After FF, female and male faculty compensation was similar (P = 0.32). Average time to promotion for female (N = 29) and male faculty (N = 82) was similar for promotion to associate professor (P = 0.49) and to full professor (P = 0.37). Promotion was associated with significantly higher retention for both genders (P < 0.001). The median time of departure was similar between female and male faculty (P = 0.73). CONCLUSIONS: A university-wide objective compensation plan increased faculty salaries to the AAMC western region median, allowing correction of gender-based salary inequity. Time to promotion and retention was similar between female and male faculty.

Ensuring Equity, Diversity, and Inclusion in Academic Surgery: An American Surgical Association White Paper.

OBJECTIVE: The leadership of the American Surgical Association (ASA) appointed a Task Force to objectively address issues related to equity, diversity, and inclusion with the discipline of academic surgery. SUMMARY OF BACKGROUND DATA: Surgeons and the discipline of surgery, particularly academic surgery, have a tradition of leadership both in medicine and society. Currently, we are being challenged to harness our innate curiosity, hard work, and perseverance to address the historically significant deficiencies within our field in the areas of diversity, equity, and inclusion. METHODS: The ASA leadership requested members to volunteer to serve on a Task Force to comprehensively address equity, diversity, and inclusion in academic surgery. Nine work groups reviewed the current literature, performed primary qualitative interviews, and distilled available guidelines and published primary source materials. A work product was created and published on the ASA Website and made available to the public. The full work product was summarized into this White Paper. RESULTS: The ASA has produced a handbook entitled: Ensuring Equity, Diversity, and Inclusion in Academic Surgery, which identifies issues and challenges, and develops a set of solutions and benchmarks to aid the academic surgical community in achieving these goals. CONCLUSION: Surgery must identify areas for improvement and work iteratively to address and correct past deficiencies. This requires honest and ongoing identification and correction of implicit and explicit biases. Increasing diversity in our departments, residencies, and universities will improve patient care, enhance productivity, augment community connections, and achieve our most fundamental ambition-doing good for our patients.

A comparison of prognosis calculators for geriatric trauma: A Prognostic Assessment of Life and Limitations After Trauma in the Elderly consortium study.

BACKGROUND: The nine-center Prognostic Assessment of Life and Limitations After Trauma in the Elderly consortium has validated the Geriatric Trauma Outcome Score (GTOS) as a prognosis calculator for injured elders. We compared GTOS' performance to that of the Trauma Injury Severity Score (TRISS) in a multicenter sample. METHODS: Three Prognostic Assessment of Life and Limitations After Trauma in the Elderly centers not submitting subjects to the GTOS validation study identified subjects aged 65 years to 102 years admitted from 2000 to 2013. GTOS was specified using the formula [GTOS = age + (Injury Severity Score [ISS] × 2.5) + 22 (if transfused packed red cells (PRC) at 24 hours)]. TRISS uses the Revised Trauma Score (RTS), dichotomizes age (<55 years = 0 and ≥55 years = 1), and was specified using the updated 1995 beta coefficients. TRISS Penetrating was specified as [TRISSP = -2.5355 + (0.9934 × RTS) + (-0.0651 × ISS) + (-1.1360 × Age)]. TRISS Blunt was specified as [TRISSB = -0.4499 + (0.8085 × RTS Total) + (-0.0835 × ISS) + (-1.7430 × Age)]. Each then became the sole predictor in a separate logistic regression model to estimate probability of mortality. Model performances were evaluated using misclassification rate, Brier score, and area under the curve. RESULTS: Demographics (mean + SD) of subjects with complete data (N = 10,894) were age, 78.3 years ± 8.1 years; ISS, 10.9 ± 8.4; RTS = 7.5 ± 1.1; mortality = 6.9%; blunt mechanism = 98.6%; 3.1 % of subjects received PRCs. The penetrating trauma subsample (n = 150) had a higher mortality rate of 20.0%. The misclassification rates for the models were GTOS, 0.065; TRISSB, 0.051; and TRISSP, 0.120. Brier scores were GTOS, 0.052; TRISSB, 0.041; and TRISSP, 0.084. The area under the curves were GTOS, 0.844; TRISSB, 0.889; and TRISSP, 0.897. CONCLUSION: GTOS and TRISS function similarly and accurately in predicting probability of death for injured elders. GTOS has the advantages of a single formula, fewer variables, and no reliance on data collected in the emergency room or by other observers. LEVEL OF EVIDENCE: Prognostic, level II.

Multicenter external validation of the Geriatric Trauma Outcome Score: A study by the Prognostic Assessment of Life and Limitations After Trauma in the Elderly (PALLIATE) consortium.

BACKGROUND: A prognostic tool for geriatric mortality after injury called the Geriatric Trauma Outcome Score (GTOS), where GTOS = [age] + [ISS × 2.5] + [22 if transfused any PRBCs by 24 hours after admission], was previously developed based on 13 years of data from geriatric trauma patients admitted to Parkland Hospital. We sought to validate this model. METHODS: Four Level I centers identified subjects who are 65 years or older for the period of the original study. The GTOS model was first specified using the formula [GTOS = age + (ISS × 2.5) + 22 (if given PRBC by 24 hours)] developed from the Parkland sample and then used as the sole predictor in a logistic mixed model estimating probability of mortality in the validation sample, accounting for site as a random effect. We estimated the misclassification (error) rate, Brier score, Tjur R, and the area under the curve in evaluating the predictive performance of the GTOS model. RESULTS: The original Parkland sample (n = 3,841) had a mean (SD) age of 76.6 (8.1) years, mean (SD) ISS of 12.4 (9.9), mortality of 10.8%, and 11.9% receiving PRBCs at 24 hours. The validation sample (n = 18,282) had a mean (SD) age of 77.0 (8.1) years, mean (SD) ISS of 12.3 (10.6), mortality of 11.0%, and 14.1% receiving PRBCs at 24 hours. Fitting the GTOS model to the validation sample revealed that the parameter estimates from the validation sample were similar to those of fitting it to the Parkland sample with highly overlapping 95% confidence limits. The misclassification (error) rate for the GTOS logistic model applied to the validation sample was 9.97%, similar to that of the Parkland sample (9.79%). Brier score, Tjur R, and the area under the curve for the GTOS logistic model when applied to the validation sample were 0.07, 0.25, and 0.86, respectively, compared with 0.08, 0.20, and 0.82, respectively, for the Parkland sample. CONCLUSION: With the use of the data available at 24 hours after injury, the GTOS accurately predicts in-hospital mortality for the injured elderly. LEVEL OF EVIDENCE: Prognostic study, level III.

An abdominal computed tomography may be safe in selected hypotensive trauma patients with positive Focused Assessment with Sonography in Trauma examination.

BACKGROUND: Positive Focused Assessment with Sonography in Trauma examination and hypotension often indicate urgent surgery. An abdomen/pelvis computed tomography (apCT) may allow less invasive management but the delay may be associated with adverse outcomes. METHODS: Patients in the Prospective Observational Multicenter Major Trauma Transfusion study with hypotension and a positive Focused Assessment with Sonography in Trauma (HF+) examination who underwent a CT (apCT+) were compared with those who did not. RESULTS: Of the 92 HF+ identified, 32 (35%) underwent apCT during initial evaluation and apCT was associated with decreased odds of an emergency operation (odds ratio .11, 95% confidence interval .001 to .116) and increased odds of angiographic intervention (odds ratio 14.3, 95% confidence interval 1.5 to 135). There was no significant difference in 30-day mortality or need for dialysis. CONCLUSIONS: An apCT in HF+ patients is associated with reduced odds of emergency surgery, but not mortality. Select HF+ patients can safely undergo apCT to obtain clinically useful information.

Palliative care training in surgical oncology and hepatobiliary fellowships: a national survey of the fellows.

BACKGROUND: Surgical oncologists (SO) and hepatobiliary (HPB) surgeons frequently care for patients with advanced diseases near the end of life, yet little is known about their training, comfort, and readiness in the provision of palliative care. This study sought to assess the quality, adequacy, and extent of palliative care training and the readiness of SO and HPB fellows in delivering palliative care. METHODS: A self-administered survey was distributed to all fellows enrolled in Society of Surgical Oncology (SSO) and HPB fellowships during the 2013-2014 academic year. The survey assessed attitudes, training, experience, and readiness of fellows in caring for patients at the end of life. Descriptive analysis was performed, and Chi square, Student's t test, and the Mann-Whitney U test were used to compare mean or median values as appropriate. RESULTS: The response rate was 47.2 %, and 50.9 % of the fellows reported exposure to a palliative care specialty service during their fellowship. Of the study participants, 75 % observed their faculty discussing the side effects of surgery compared with 54 % who observed faculty communication with patients regarding end-of-life goals (p < 0.01). On the other hand, 40 % of the fellows were never observed by faculty discussing symptoms management, goals of care, or hospice referral with patients, and 56.7 % never received feedback on their palliative skills. CONCLUSION: The fellows rated the quality of their palliative care education as poor compared with other aspects of their fellowship training, implying the lack and need of palliative care teaching. Surgical oncology and HPB fellows and ultimately patients may benefit from increased clinical and didactic palliative care training.

Purposeful variable selection and stratification to impute missing Focused Assessment with Sonography for Trauma data in trauma research.

BACKGROUND: The Focused Assessment with Sonography for Trauma (FAST) examination is an important variable in many retrospective trauma studies. The purpose of this study was to devise an imputation method to overcome missing data for the FAST examination. Owing to variability in patients' injuries and trauma care, these data are unlikely to be missing completely at random, raising concern for validity when analyses exclude patients with missing values. METHODS: Imputation was conducted under a less restrictive, more plausible missing-at-random assumption. Patients with missing FAST examinations had available data on alternate, clinically relevant elements that were strongly associated with FAST results in complete cases, especially when considered jointly. Subjects with missing data (32.7%) were divided into eight mutually exclusive groups based on selected variables that both described the injury and were associated with missing FAST values. Additional variables were selected within each group to classify missing FAST values as positive or negative, and correct FAST examination classification based on these variables was determined for patients with nonmissing FAST values. RESULTS: Severe head/neck injury (odds ratio [OR], 2.04), severe extremity injury (OR, 4.03), severe abdominal injury (OR, 1.94), no injury (OR, 1.94), other abdominal injury (OR, 0.47), other head/neck injury (OR, 0.57), and other extremity injury (OR, 0.45) groups had significant ORs for missing data; the other group's OR was not significant (OR, 0.84). All 407 missing FAST values were imputed, with 109 classified as positive. Correct classification of nonmissing FAST results using the alternate variables was 87.2%. CONCLUSION: Purposeful imputation for missing FAST examinations based on interactions among selected variables assessed by simple stratification may be a useful adjunct to sensitivity analysis in the evaluation of imputation strategies under different missing data mechanisms. This approach has the potential for widespread application in clinical and translational research, and validation is warranted.

Physician reimbursement for critical care services integrating palliative care for patients who are critically ill.

Patients with advanced illness often spend time in an ICU, while nearly one-third of patients with advanced cancer who receive Medicare die in hospitals, often with failed ICU care. For most, death occurs following the withdrawal or withholding of life-sustaining treatments. The integration of palliative care is essential for high-quality critical care. Although palliative care specialists are becoming increasingly available, intensivists and other physicians are also expected to provide basic palliative care, including symptom treatment and communication about goals of care. Patients who are critically ill are often unable to make decisions about their care. In these situations, physicians must meet with family members or other surrogates to determine appropriate medical treatments. These meetings require clinical expertise to ensure that patient values are explored for medical decision making about therapeutic options, including palliative care. Meetings with families take time. Issues related to the disease process, prognosis, and treatment plan are complex, and decisions about the use or limitation of intensive care therapies have life-or-death implications. Inadequate reimbursement for physician services may be a barrier to the optimal delivery of high-quality palliative care, including effective communication. Appropriate documentation of time spent integrating palliative and critical care for patients who are critically ill can be consistent with the Current Procedural Terminology codes (99291 and 99292) for critical care services. The purpose of this article is to help intensivists and other providers understand the circumstances in which integration of palliative and critical care meets the definition of critical care services for billing purposes.

Health services research resources for surgeons.

BACKGROUND: Health services research examines how people get access to health care, how much care costs, and what happens to patients as a result of this care. Some of the challenges to conducting methodologically rigorous health services research as a surgeon are support, training, funding, acquisition of data, and resources. MATERIALS AND METHODS: A review of support, training, funding, data, and organizational resources useful for surgeons interested in health services research, with a focus on existing online resources relevant to surgical health services researchers. RESULTS: Opportunities for research collaboration and mentoring are available through the Association for Academic Surgery, Society of University Surgeons, American College of Surgeons and surgical specialty societies. Advanced training is essential to performing high-impact health services research and is available through private foundations such as the Robert Wood Johnson Clinical Scholars program, the American College of Surgeons Fellowship, government funded fellowships, and institution hosted fellowships. Funding sources for health services research exist through academic surgical societies, private sector, and government sources. A variety of data sources for health services research are available, with different limitations, strengths, and ease of accessibility. Organizational resources in health services research include AcademyHealth, the Health Services Research Projects in Progress database, and the National Library of Medicine's Health Services Research Resources. CONCLUSIONS: The resources highlighted describe some of the opportunities available to surgeons pursuing health services research. It is valuable for surgeons to tap into the available resources and collaborate with existing expertise to facilitate methodologically rigorous surgical health services research.

Screening for blunt cerebrovascular injuries is cost-effective.

BACKGROUND: Screening for blunt carotid and vertebral injury (BCVI) is increasing without a clear understanding of whether the chosen screening approach is cost-effective. We hypothesized that screening for BCVI using computed tomography angiography (CTA) was cost-effective in populations at high risk for BCVI. METHODS: A decision analysis was performed modeling current BCVI screening approaches: no screening, duplex ultrasound, magnetic resonance angiography, angiography, and CTA. Treatment options included antiplatelet therapy, anticoagulation, stents for pseudoaneurysm, and no treatment. Probability estimates for incidence of injury and stroke, sensitivity and specificity of the screening modality, and type of treatment were taken from published data. Average wholesale price and medicare reimbursement costs were used. Two populations were analyzed; high-risk and overall blunt trauma populations. Two perspectives were taken; societal (including lifetime stroke costs) and institutional (ignoring lifetime stroke costs). RESULTS: In the high-risk population, from a societal perspective, CTA has the lowest cost and stroke rate; $3,727 per patient screened with a 1% stroke rate. No treatment has the highest cost and stroke rate. From an institutional perspective, no screening is the least costly option but has an 11% stroke rate. Duplex ultrasound is the most cost-effective screening modality; $8,940 per stroke prevented. CONCLUSION: From the societal perspective, CTA is the most cost-effective screening strategy for patients at high risk for BCVI. From an institutional perspective, CTA prevents the most strokes at a reasonable cost.

Cost-effective treatment of patients with symptomatic cholelithiasis and possible common bile duct stones.

BACKGROUND: Clinicians must choose a treatment strategy for patients with symptomatic cholelithiasis without knowing whether common bile duct (CBD) stones are present. The purpose of this study was to determine the most cost-effective treatment strategy for patients with symptomatic cholelithiasis and possible CBD stones. STUDY DESIGN: Our decision model included 5 treatment strategies: laparoscopic cholecystectomy (LC) alone followed by expectant management; preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by LC; LC with intraoperative cholangiography (IOC) ± common bile duct exploration (CBDE); LC followed by postoperative ERCP; and LC with IOC ± postoperative ERCP. The rates of successful completion of diagnostic testing and therapeutic intervention, test characteristics (sensitivity and specificity), morbidity, and mortality for all procedures are from current literature. Hospitalization costs and lengths of stay are from the 2006 National Centers for Medicare and Medicaid Services data. The probability of CBD stones was varied from 0% to 100% and the most cost-effective strategy was determined at each probability. RESULTS: Across the CBD stone probability range of 4% to 100%, LC with IOC ± ERCP was the most cost-effective. If the probability was 0%, LC alone was the most cost-effective. Our model was sensitive to 1 health input: specificity of IOC, and 3 costs: cost of hospitalization for LC with CBDE, cost of hospitalization for LC without CBDE, and cost of LC with IOC. CONCLUSIONS: The most cost-effective treatment strategy for the majority of patients with symptomatic cholelithiasis is LC with routine IOC. If stones are detected, CBDE should be forgone and the patient referred for ERCP.

Putting a price on education: hours and dollars for a general surgery curriculum.

BACKGROUND: In 2005, a new curricular model was implemented for general surgery residents and a Division of Education created for administrative support. These changes forced an evaluation of available resources to maintain a new curricular model. METHODS: A retrospective review of resources expended during curricular sessions (June 2007-June 2008) provided to 42 surgical residents was conducted. Resources were evaluated in terms of the number, division, department, and rank of faculty involved. Contact hours and monetary costs were calculated. RESULTS: Total numbers of faculty involved in the postgraduate year (PGY)1, PGY2, and PGY3-5 curriculums were 79, 39, and 22, respectively. Faculty teaching time was 321 hours (PGY1), 187 hours (PGY2) and 36 hours (PGY3-5) for a combined 544 hours. Average teaching time commitment for faculty in the Division of Education was 26.5 hours, compared with 6.7 hours for departmental faculty in other divisions (P = .0002). Total monetary cost was $219,254. CONCLUSIONS: The cost to maintain an educational general surgery curriculum is substantial and administrative support must be considered. Faculty with an explicit teaching commitment and responsibility are needed.

Cost-effectiveness of prolonged thromboprophylaxis after cancer surgery.

BACKGROUND: Consensus guidelines recommend prolonged thromboprophylaxis for up to 4 weeks after major abdominopelvic cancer operations. Several factors impede widespread adoption of these guidelines. These include lack of awareness, cost, increased bleeding complications, increased incidence of heparin-induced thrombocytopenia, and poor patient compliance. METHODS: A cost-effectiveness model was constructed comparing four potential strategies to postdischarge thromboprophylaxis in surgical oncology patients: (1) low-molecular-weight heparin (LMWH) once daily; (2) low-dose unfractionated heparin (LDUH) three times daily; (3) oral aspirin once daily; or (4) no prolonged prophylaxis. Probabilities and costs were estimated on the basis of published literature and average Medicare reimbursement. The decision analysis was conducted from the perspective of the health care system, with the primary end point being cost per patient without venous thromboembolism (VTE). Sensitivity analyses tested the robustness of the results. RESULTS: LDUH was most cost-effective, saving $154 per patient without VTE compared with no prophylaxis. LMWH was not cost-effective, incurring a cost of $230 per patient without VTE compared with no prophylaxis. Aspirin was a viable alternative to LDUH, saving $123 compared with no prophylaxis. When poor compliance was considered, aspirin became the dominant strategy. Sensitivity analyses failed to show any instance where LMWH was cost-effective. In terms of population costs, widespread use of LDUH after discharge would save $30.3 million per year in the United States. CONCLUSIONS: Although all chemical prophylaxis is effective in preventing VTE in the outpatient setting after cancer surgery, either LDUH or aspirin are the most cost-effective, depending on patient compliance.

The random dialing survey as a tool for community consultation for research involving the emergency medicine exception from informed consent.

STUDY OBJECTIVE: In 1996, the Food and Drug Administration and the Department of Health and Human Services enacted rules allowing a narrow exception from informed consent for critically ill patients enrolled in emergency research. These include requirements for community consultation prior to trial implementation. Previous studies have noted difficulty in engaging the community. We seek to describe the experience with random dialing surveys as a tool for community consultation across 5 metropolitan regions in the United States. METHODS: Random dialing surveys were used as part of the community consultation for an out-of-hospital clinical trial sponsored by the Resuscitation Outcomes Consortium. The survey method was designed to obtain a representative sample of the community according to population demographics and geography. Logistics of survey administration, role of the survey in community consultation, and survey results by population demographics are discussed. RESULTS: Random dialing surveys were conducted in 5 of 8 US Resuscitation Outcomes Consortium sites. Overall, 70% to 79% of respondents indicated they would be willing to be enrolled in this study. Support for the inclusion of children (aged 15 to 18 years) ranged from 52% to 71%. Respondents aged 18 to 34 years were more willing to participate in the trial than older age groups. Women and racial minorities were less likely to favor the inclusion of minors. CONCLUSION: Random dialing surveys provide an additional tool to engage the community and obtain a sample of the opinion of the population about research conducted under the emergency exception from informed consent regulations. Similar results were obtained across 5 diverse communities in the United States.
