COVID-19 Impact on Surgical Resident Education and Coping.

BACKGROUND: Healthcare systems and surgical residency training programs have been significantly affected by the novel coronavirus disease 2019 (COVID-19) pandemic. A shelter-in-place and social distancing mandate went into effect in our county on March 16, 2020, considerably altering clinical and educational operations. Along with the suspension of elective procedures, resident academic curricula transitioned to an entirely virtual platform. We aimed to evaluate the impact of these modifications on surgical training and resident concerns about COVID-19. MATERIALS AND METHODS: We surveyed residents and fellows from all eight surgical specialties at our institution regarding their COVID-19 experiences from March to May 2020. Residents completed the survey via a secure Qualtrics link. A total of 38 questions addressed demographic information and perspectives regarding the impact of the COVID-19 pandemic on surgical training, education, and general coping during the pandemic. RESULTS: Of 256 eligible participants across surgical specialties, 146 completed the survey (57.0%). Junior residents comprised 43.6% (n = 61), compared to seniors 37.1% (n = 52) and fellows 19.3% (n = 27). Most participants, 97.9% (n = 138), anticipated being able to complete their academic year on time, and 75.2% (n = 100) perceived virtual learning to be the same as or better than in-person didactic sessions. Participants were most concerned about their ability to have sufficient knowledge and skills to care for patients with COVID-19, and the possibility of exposure to COVID-19. CONCLUSIONS: Although COVID-19 impacted residents' overall teaching and clinical volume, residency programs may identify novel virtual opportunities to meet their educational and research milestones during these challenging times.

Do hospital-based emergency Medicaid programs benefit trauma centers? A mixed-methods analysis.

INTRODUCTION: Hospital Presumptive Eligibility (HPE) is a temporary Medicaid insurance at hospitalization, which can offset patient costs of care, increase access to postdischarge resources, and provide a path to sustain coverage through Medicaid. Less is known about the implications of HPE programs on trauma centers (TCs). We aimed to describe the association with HPE and hospital Medicaid reimbursement and characterize incentives for HPE participation among hospitals and TCs. We hypothesized that there would be financial, operational, and mission-based incentives. METHODS: We performed a convergent mixed methods study of HPE hospitals in California (including all verified TCs). We analyzed Annual Financial Disclosure Reports from California's Department of Health Care Access and Information (2005-2021). Our primary outcome was Medicaid net revenue. We also conducted thematic analysis of semistructured interviews with hospital stakeholders to understand incentives for HPE participation (n = 8). RESULTS: Among 367 California hospitals analyzed, 285 (77.7%) participate in HPE, 77 (21%) of which are TCs. As of early 2015, 100% of TCs had elected to enroll in HPE. There is a significant positive association between HPE participation and net Medicaid revenue. The highest Medicaid revenues are in HPE level I and level II TCs. Controlling for changes associated with the Affordable Care Act, HPE enrollment is associated with increased net patient Medicaid revenue ( b = 6.74, p < 0.001) and decreased uncompensated care costs ( b = -2.22, p < 0.05). Stakeholder interviewees' explanatory incentives for HPE participation included reduction of hospital bad debt, improved patient satisfaction, and community benefit in access to care. CONCLUSION: Hospital Presumptive Eligibility programs not only are a promising pathway for long-term insurance coverage for trauma patients but also play a role in TC viability. Future interventions will target streamlining the HPE Medicaid enrollment process to reduce resource burden on participating hospitals and ensure ongoing patient engagement in the program.

Financial toxicity part II: A practical guide to measuring and tracking long-term financial outcomes among acute care surgery patients.

ABSTRACT: Acute care surgery (ACS) patients are frequently faced with significant long-term recovery and financial implications that extend far beyond their hospitalization. While major injury and emergency general surgery (EGS) emergencies are often viewed solely as acute moments of crisis, the impact on patients can be lifelong. Financial outcomes after major injury or emergency surgery have only begun to be understood. The Healthcare Economics Committee from the American Association for the Surgery of Trauma previously published a conceptual overview of financial toxicity in ACS, highlighting the association between financial outcomes and long-term physical recovery. The aims of second-phase financial toxicity review by the Healthcare Economics Committee of the American Association for the Surgery of Trauma are to (1) understand the unique impact of financial toxicity on ACS patients; (2) delineate the current limitations surrounding measurement domains of financial toxicity in ACS; (3) explore the "when, what and how" of optimally capturing financial outcomes in ACS; and (4) delineate next steps for integration of these financial metrics in our long-term patient outcomes. As acute care surgeons, our patients' recovery is often contingent on equal parts physical, emotional, and financial recovery. The ACS community has an opportunity to impact long-term patient outcomes and well-being far beyond clinical recovery.

Managing career transitions in the profession of acute care surgery.

Career shifts are a naturally occurring part of the trauma and acute care surgeon's profession. These transitions may occur at various timepoints throughout a surgeon's career and each has their own specific challenges. Finding a good fit for your first job is critical for ensuring success as an early career surgeon. Equally, understanding how to navigate promotions or a change in job location mid-career can be fraught with uncertainty. As one progresses in their career, knowing when to take on a leadership position is oftentimes difficult as it may mean a change in priorities. Finally, navigating your path towards a fulfilling retirement is a complex discussion that is different for each surgeon. The American Association for the Surgery of Trauma (AAST) convened an expert panel of acute care surgeons in a virtual grand rounds session in August 2023 to address the aforementioned career transitions and highlight strategies for successfully navigating each shift. This was a collaboration between the AAST Associate Member Council (consisting of surgical resident, fellow and junior faculty members), the AAST Military Liaison Committee and the AAST Healthcare Economics Committee. Led by two moderators, the panel consisted of early, mid-career and senior surgeons, and recommendations are summarized below and in figure 1.

Weight-based enoxaparin thromboprophylaxis in young trauma patients: analysis of the CLOTT-1 registry.

Introduction: Optimal venous thromboembolism (VTE) enoxaparin prophylaxis dosing remains elusive. Weight-based (WB) dosing safely increases anti-factor Xa levels without the need for routine monitoring but it is unclear if it leads to lower VTE risk. We hypothesized that WB dosing would decrease VTE risk compared with standard fixed dosing (SFD). Methods: Patients from the prospective, observational CLOTT-1 registry receiving prophylactic enoxaparin (n=5539) were categorized as WB (0.45-0.55 mg/kg two times per day) or SFD (30 mg two times per day, 40 mg once a day). Multivariate logistic regression was used to generate a predicted probability of VTE for WB and SFD patients. Results: Of 4360 patients analyzed, 1065 (24.4%) were WB and 3295 (75.6%) were SFD. WB patients were younger, female, more severely injured, and underwent major operation or major venous repair at a higher rate than individuals in the SFD group. Obesity was more common among the SFD group. Unadjusted VTE rates were comparable (WB 3.1% vs. SFD 3.9%; p=0.221). Early prophylaxis was associated with lower VTE rate (1.4% vs. 5.0%; p=0.001) and deep vein thrombosis (0.9% vs. 4.4%; p<0.001), but not pulmonary embolism (0.7% vs. 1.4%; p=0.259). After adjustment, VTE incidence did not differ by dosing strategy (adjusted OR (aOR) 0.75, 95% CI 0.38 to 1.48); however, early administration was associated with a significant reduction in VTE (aOR 0.47, 95% CI 0.30 to 0.74). Conclusion: In young trauma patients, WB prophylaxis is not associated with reduced VTE rate when compared with SFD. The timing of the initiation of chemoprophylaxis may be more important than the dosing strategy. Further studies need to evaluate these findings across a wider age and comorbidity spectrum. Level of evidence: Level IV, therapeutic/care management.

Liberian surgical and anesthesia infrastructure: a survey of county hospitals.

BACKGROUND: There is a significant burden of disease in low-income countries that can benefit from surgical intervention. The goal of this survey was to evaluate the current ability of the Liberian health care system to provide safe surgical care and to identify unmet needs in regard to trained personnel, equipment, infrastructure, and outcomes measurement. METHODS: A comprehensive survey tool was developed to assess physical infrastructure of operative facilities, education and training for surgical and anesthesia providers, equipment and medications, and the capacity of the surgical system to collect and evaluate surgical outcomes at district-level hospitals in Africa. This tool was implemented in a sampling of 11 county hospitals in Liberia (January 2011). Data were obtained from the Ministry of Health and by direct government-affiliated hospital site visits. RESULTS: The total catchment area of the 11 hospitals surveyed was 2,313,429--equivalent to roughly 67 % of the population of Liberia (3,476,608). There were 13 major operating rooms and 34 (1.5 per 100,000 population) physicians delivering surgical, obstetric, or anesthesia care including 2 (0.1 per 100,000 population) who had completed formal postgraduate training programs in these specialty areas. The total number of surgical cases for 2010 was 7,654, with approximately 43 % of them being elective procedures. Among the facilities that tracked outcomes in 2010, a total of 11 intraoperative deaths (145 per 100,000 operative cases) were recorded for 2009. The 30-day postoperative mortality at hospitals providing data was 44 (1,359 per 100,000 operative cases). Metrics were also used to evaluate surgical output, safety of anesthesia, and the burden of obstetric disease. CONCLUSIONS: A significant volume of surgical care is being delivered at county hospitals throughout Liberia. The density and quality of appropriately trained personnel and infrastructure remain critically low. There is strong evidence for continued development of emergency and essential surgical services, as well as improved surgical outcomes tracking, at county hospitals in Liberia. These results serve to inform the international community and donors of the ongoing global surgical and anesthesia crisis.

Does tranexamic acid increase venous thromboembolism risk among trauma patients? A prospective multicenter analysis across 17 level I trauma centers.

IMPORTANCE: The early use of tranexamic acid (TXA) has demonstrated benefit among some trauma patients in hemorrhagic shock. The association between TXA administration and thromboembolic events (including deep vein thrombosis (DVT), pulmonary embolism (PE) and pulmonary thrombosis (PT)) remains unclear. We aimed to characterize the risk of venous thromboembolism (VTE) subtypes among trauma patients receiving TXA and to determine whether TXA is associated with VTE risk and mortality. METHODS: We analyzed a prospective, observational, multicenter cohort data from the Consortium of Leaders in the Study of Traumatic Thromboembolism (CLOTT) study group. The study was conducted across 17 US level I trauma centers between January 1, 2018, and December 31,2020. We studied trauma patients ages 18-40 years, admitted for at least 48 h with a minimum of 1 VTE risk factor and followed until hospital discharge or 30 days. We compared TXA recipients to non-recipients for VTE and mortality using inverse probability weighted Cox models. The primary outcome was the presence of documented venous thromboembolism (VTE). The secondary outcome was mortality. VTE was defined as DVT, PE, or PT. RESULTS: Among the 7,331 trauma patients analyzed, 466 (6.4%) received TXA. Patients in the TXA group were more severely injured than patients in the non-TXA group (ISS 16+: 69.1% vs. 48.5%, p < 0.001) and a higher percentage underwent a major surgical procedure (85.8% vs. 73.6%, p < 0.001). Among TXA recipients, 12.5% developed VTE (1.3% PT, 2.4% PE, 8.8% DVT) with 5.6% mortality. In the non-TXA group, 4.6% developed VTE (1.1% PT, 0.5% PE, 3.0% DVT) with 1.7% mortality. In analyses adjusting for patient demographic and clinical characteristics, TXA administration was not significantly associated with VTE (aHR 1.00, 95%CI: 0.69-1.46, p = 0.99) but was significantly associated with increased mortality (aHR 2.01, 95%CI: 1.46-2.77, p < 0.001). CONCLUSION: TXA was not clearly identified as an independent risk factor for VTE in adjusted analyses, but the risk of VTE among trauma patients receiving TXA remains high (12.5%). This supports the judicious use of TXA in resuscitation, with consideration of early initiation of DVT prophylaxis in this high-risk group.

Financial toxicity after trauma and acute care surgery: From understanding to action.

ABSTRACT: Gains in inpatient survival over the last five decades have shifted the burden of major injuries and surgical emergencies from the acute phase to their long-term sequelae. More attention has been placed on evaluation and optimization of long-term physical and mental health; however, the impact of major injuries and surgical emergencies on long-term financial well-being remains a critical blind spot for clinicians and researchers. The concept of financial toxicity encompasses both the objective financial consequences of illness and medical care as well as patients' subjective financial concerns. In this review, representatives of the Healthcare Economics Committee from the American Association for the Surgery of Trauma (1) provide a conceptual overview of financial toxicity after trauma or emergency surgery, (2) outline what is known regarding long-term economic outcomes among trauma and emergency surgery patients, (3) explore the bidirectional relationship between financial toxicity and long-term physical and mental health outcomes, (4) highlight policies and programs that may mitigate financial toxicity, and (5) identify the current knowledge gaps and critical next steps for clinicians and researchers engaged in this work.

Power of mentorship for civilian and military acute care surgeons: identifying and leveraging opportunities for longitudinal professional development.

Across disciplines, mentorship has been recognized as a key to success. Acute care surgeons, focused on the care of trauma surgery, emergency general surgery and surgical critical care, practice in a wide variety of settings and have unique mentorship needs across all phases of their career. Recognizing the need for robust mentorship and professional development, the American Association for the Surgery of Trauma (AAST) convened an expert panel entitled 'The Power of Mentorship' at the 81st annual meeting in September 2022 (Chicago, Illinois). This was a collaboration between the AAST Associate Member Council (consisting of surgical resident, fellow and junior faculty members), the AAST Military Liaison Committee, and the AAST Healthcare Economics Committee. Led by two moderators, the panel consisted of five real-life mentor-mentee pairs. They addressed the following realms of mentorship: clinical, research, executive leadership and career development, mentorship through professional societies, and mentorship for military-trained surgeons. Recommendations, as well as pearls and pitfalls, are summarized below.

Challenges of surgery in developing countries: a survey of surgical and anesthesia capacity in Uganda's public hospitals.

BACKGROUND: There are large disparities in access to surgical services due to a multitude of factors, including insufficient health human resources, infrastructure, medicines, equipment, financing, logistics, and information reporting. This study aimed to assess these important factors in Uganda's government hospitals as part of a larger study examining surgical and anesthesia capacity in low-income countries in Africa. METHODS: A standardized survey tool was administered via interviews with Ministry of Health officials and key health practitioners at 14 public government hospitals throughout the country. Descriptive statistics were used to analyze the data. RESULTS: There were a total of 107 general surgeons, 97 specialty surgeons, 124 obstetricians/gynecologists (OB/GYNs), and 17 anesthesiologists in Uganda, for a rate of one surgeon per 100,000 people. There was 0.2 major operating theater per 100,000 people. Altogether, 53% of all operations were general surgery cases, and 44% were OB/GYN cases. In all, 73% of all operations were performed on an emergency basis. All hospitals reported unreliable supplies of water and electricity. Essential equipment was missing across all hospitals, with no pulse oximeters found at any facilities. A uniform reporting mechanism for outcomes did not exist. CONCLUSIONS: There is a lack of vital human resources and infrastructure to provide adequate, safe surgery at many of the government hospitals in Uganda. A large number of surgical procedures are undertaken despite these austere conditions. Many areas that need policy development and international collaboration are evident. Surgical services need to become a greater priority in health care provision in Uganda as they could promise a significant reduction in morbidity and mortality.

Data resources for evaluating the economic and financial consequences of surgical care in the United States.

ABSTRACT: Evaluating the relationship between health care costs and quality is paramount in the current health care economic climate, as an understanding of value is needed to drive policy decisions. While many policy analyses are focused on the larger health care system, there is a pressing need for surgically focused economic analyses. Surgical care is costly, and innovative technology is constantly introduced into the operating room, and surgical care impacts patients' short- and long-term physical and economic well-being. Unfortunately, significant knowledge gaps exist regarding the relationship between cost, value, and economic impact of surgical interventions. Despite the plethora of health care data available in the forms of claims databases, discharge databases, and national surveys, no single source of data contains all the information needed for every policy-relevant analysis of surgical care. For this reason, it is important to understand which data are available and what can be accomplished with each of the data sets. In this article, we provide an overview of databases commonly used in surgical health services research. We focus our review on the following five categories of data: governmental claims databases, commercial claims databases, hospital-based clinical databases, state and national discharge databases, and national surveys. For each, we present a summary of the database sampling frame, clinically relevant variables, variables relevant to economic analyses, strengths, weaknesses, and examples of surgically relevant analyses. This review is intended to improve understanding of the current landscape of data available, as well as stimulate novel analyses among surgical populations. Ongoing debates over national health policy reforms may shape the delivery of surgical care for decades to come. Appropriate use of available data resources can improve our understanding of the economic impact of surgical care on our health care system and our patients.

Rwandan surgical and anesthesia infrastructure: a survey of district hospitals.

BACKGROUND: In low-income countries, unmet surgical needs lead to a high incidence of death. Information on the incidence and safety of current surgical care in low-income countries is limited by the paucity of data in the literature. The aim of this survey was to assess the surgical and anesthesia infrastructure in Rwanda as part of a larger study examining surgical and anesthesia capacity in low-income African countries. METHODS: A comprehensive survey tool was developed to assess the physical infrastructure of operative facilities, education and training for surgical and anesthesia providers, and equipment and medications at district-level hospitals in sub-Saharan Africa. The survey was administered at 21 district hospitals in Rwanda using convenience sampling. RESULTS: There are only nine Rwandan anesthesiologists and 17 Rwandan surgeons providing surgical care for a population of more than 10 million. The specialty-trained Rwandan surgeons and anesthesiologists are practicing almost exclusively at referral hospitals, leaving surgical care at district hospitals to the general practice physicians and nurses. All of the district hospitals reported some lack of surgical infrastructure including limited access to oxygen, anesthesia equipment and medications, monitoring equipment, and trained personnel. CONCLUSIONS: This survey provides strong evidence of the need for continued development of emergency and essential surgical services at district hospitals in Rwanda to improve health care and to comply with World Health Organization recommendations. It has identified serious deficiencies in both financial and human resources-areas where the international community can play a role.

Consensus statements regarding the multidisciplinary care of limb amputation patients in disasters or humanitarian emergencies: report of the 2011 Humanitarian Action Summit Surgical Working Group on amputations following disasters or conflict.

Limb amputations are frequently performed as a result of trauma inflicted during conflict or disasters. As demonstrated during the 2010 earthquake in Haiti, coordinating care of these patients in austere settings is complex. During the 2011 Humanitarian Action Summit, consensus statements were developed for international organizations providing care to limb amputation patients during disasters or humanitarian emergencies. Expanded planning is needed for a multidisciplinary surgical care team, inclusive of surgeons, anesthesiologists, rehabilitation specialists and mental health professionals. Surgical providers should approach amputation using an operative technique that optimizes limb length and prosthetic fitting. Appropriate anesthesia care involves both peri-operative and long-term pain control. Rehabilitation specialists must be involved early in treatment, ideally before amputation, and should educate the surgical team in prosthetic considerations. Mental health specialists must be included to help the patient with community reintegration. A key step in developing local health systems the establishment of surgical outcomes monitoring. Such monitoring can optimizepatient follow-up and foster professional accountability for the treatment of amputation patients in disaster settings and humanitarian emergencies.

Acquisition of Medicaid at the time of injury: An opportunity for sustainable insurance coverage.

INTRODUCTION: Uninsured trauma patients are at higher risk of mortality, limited access to postdischarge resources, and catastrophic health expenditure. Hospital Presumptive Eligibility (HPE), enacted with the 2014 Affordable Care Act, enables uninsured patients to be screened and acquired emergency Medicaid at the time of hospitalization. We sought to identify factors associated with successful acquisition of HPE insurance at the time of injury, hypothesizing that patients with higher Injury Severity Score (ISS) (ISS >15) would be more likely to be approved for HPE. METHODS: We identified Medicaid and uninsured patients aged 18 to 64 years with a primary trauma diagnosis (International Classification of Diseases, Tenth Revision) in a large level I trauma center between 2015 and 2019. We combined trauma registry data with review of electronic medical records, to determine our primary outcome, HPE acquisition. Descriptive and multivariate analyses were performed. RESULTS: Among 2,320 trauma patients, 1,374 (59%) were already enrolled in Medicaid at the time of hospitalization. Among those uninsured at arrival, 386 (40.8%) acquired HPE before discharge, and 560 (59.2%) remained uninsured. Hospital Presumptive Eligibility patients had higher ISS (ISS >15, 14.8% vs. 5.7%; p < 0.001), longer median length of stay (2 days [interquartile range, 0-5 days] vs. 0 [0-1] days, p < 0.001), were more frequently admitted as inpatients (64.5% vs. 33.6%, p < 0.001), and discharged to postacute services (11.9% vs. 0.9%, p < 0.001). Patient, hospital, and policy factors contributed to HPE nonapproval. In adjusted analyses, Hispanic ethnicity (vs. non-Hispanic Whites: aOR, 1.58; p = 0.02) and increasing ISS (p ≤ 0.001) were associated with increased likelihood of HPE approval. CONCLUSION: The time of hospitalization due to injury is an underused opportunity for intervention, whereby uninsured patients can acquire sustainable insurance coverage. Opportunities to increase HPE acquisition merit further study nationally across trauma centers. As administrative and trauma registries do not capture information to compare HPE and traditional Medicaid patients, prospective insurance data collection would help to identify targets for intervention.

Creation and implementation of a novel clinical workflow based on the AAST uniform anatomic severity grading system for emergency general surgery conditions.

OBJECTIVE: Emergency general surgery (EGS) conditions encompass a variety of diseases treated by acute care surgeons. The heterogeneity of these diseases limits infrastructure to facilitate EGS-specific quality improvement (QI) and research. A uniform anatomic severity grading system for EGS conditions was recently developed to fill this need. We integrated this system into our clinical workflow and examined its impact on research, surgical training, communication, and patient care. METHODS: The grading system was integrated into our clinical workflow in a phased fashion through formal education and a written handbook. A documentation template was also deployed in our electronic medical record to prospectively assign severity scores at the time of patient evaluation. Mixed methods including a quantitative survey and qualitative interviews of trainees and attending surgeons were used to evaluate the impact of the new workflow and to identify obstacles to its adoption. RESULTS: We identified 2291 patients presenting with EGS conditions during our study period. The most common diagnoses were small bowel obstruction (n=470, 20.5%), acute cholecystitis (n=384, 16.8%), and appendicitis (n=370, 16.1%). A total of 21 qualitative interviews were conducted. Twenty interviewees (95.2%) had a positive impression of the clinical workflow, citing enhanced patient care and research opportunities. Fifteen interviewees (75.0%) reported the severity grading system was a useful framework for clinical management, with five participants (25.0%) indicating the system was useful to facilitate clinical communication. Participants identified solutions to overcome barriers to adoption of the clinical workflow. CONCLUSIONS: The uniform anatomic severity grading system can be readily integrated into a clinical workflow to facilitate prospective data collection for QI and research. The system is perceived as valuable by users. Educational initiatives that focus on increasing familiarity with the system and its benefits will likely improve adoption of the classification system and the clinical workflow that uses it.

The impact of Medicaid expansion on trauma-related emergency department utilization: A national evaluation of policy implications.

BACKGROUND: The impact of the 2014 Affordable Care Act (ACA) upon national trauma-related emergency department (ED) utilization is unknown. We assessed ACA-related changes in ED use and payer mix, hypothesizing that post-ACA ED visits would decline and Medicaid coverage would increase disproportionately in regions of widespread policy adoption. METHODS: We queried the National Emergency Department Sample (NEDS) for those with a primary trauma diagnosis, aged 18 to 64. Comparing pre-ACA (2012) to post-ACA (10/2014 to 09/2015), primary outcomes were change in ED visits and payer status; secondary outcomes were change in costs, discharge disposition and inpatient length of stay. Univariate and multivariate analyses were performed, including difference-in-differences analyses. We compared changes in ED trauma visits by payer in the West (91% in a Medicaid expansion state) versus the South (12%). RESULTS: Among 21.2 million trauma-related ED visits, there was a 13.3% decrease post-ACA. Overall, there was a 7.2% decrease in uninsured ED visits (25.5% vs. 18.3%, p < 0.001) and a 6.6% increase in Medicaid coverage (17.6% vs. 24.2%, p < 0.001). Trauma patients had 40% increased odds of having Medicaid post-ACA (vs. pre-ACA: aOR 1.40, p < 0.001). Patients in the West had 31% greater odds of having Medicaid (vs. South: aOR 1.31, p < 0.001). The post-ACA increase in Medicaid was greater in the West (vs. South: aOR 1.60, p < 0.001). Post-ACA, inpatients were more likely to have Medicaid (vs. ED discharge: aOR 1.20, p < 0.001) and there was a 25% increase in inpatient discharge to rehabilitation (aOR 1.24, p < 0.001). CONCLUSION: Post-ACA, there was a significant increase in insured trauma patients and a decrease in injury-related ED visits, possibly resulting from access to other outpatient services. Ensuring sustainability of expanded coverage will benefit injured patients and trauma systems. LEVEL OF EVIDENCE: Economic, level III.
