The overtreatment of papillary thyroid microcarcinoma in the community.

INTRODUCTION: Total thyroidectomy is the traditional primary approach for papillary thyroid cancer. However, recent evidence supports conservative management for low-risk tumors like papillary thyroid microcarcinomas (PTMCs). This study explores the adoption of these practices in our community, using a cancer database to analyze treatment strategies. METHODS: A retrospective review of a 1433-patient institutional database identified 258 â€‹PTMC cases. Outcomes, including 30-day mortality, reoperation rate, postoperative hypocalcemia, and recurrent laryngeal nerve (RLN) injury, were assessed. RESULTS: Of PTMC patients, 63.4% underwent total thyroidectomy, with higher rates of RLN injury (8.8% vs. 2.3%) and hypocalcemia (12.4% vs. 0.0%) compared to lobectomy. Non-endocrine surgeons had higher postoperative radioactive iodine administration rates (28.6% vs. 6.1%). Subgroup analysis revealed a shift in total thyroidectomy rates based on tumor size and surgery period. CONCLUSION: Our community favors total thyroidectomy for PTMC, despite associated complications. Enhanced awareness and adherence to PTMC best practice guidelines are warranted.

Outcomes of patients enrolled in a prospective and randomized trial on basis of gestalt assessment or ABC score.

BACKGROUND: The Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial rapidly enrolled patients based on an Assessment of Blood Consumption (ABC) ≥ 2 score, or physician gestalt (PG) when ABC score was <2. The objective of this study was to describe what patients were enrolled by the two methods and whether patient outcomes differed based on these enrollments. We hypothesized that there would be no differences in outcomes based on whether patients were enrolled via ABC score or PG. METHODS: Patients were enrolled with an ABC ≥ 2 or by PG when ABC was <2 by the attending trauma surgeon. We compared 1-hour, 3-hour, 6-hour, 12-hour, 18-hour, and 24-hour mortality, 30-day mortality, time to hemostasis, emergent surgical or interventional radiology procedure and the proportion of patients who required either >10 units of blood in 24 hours or >3 units in 1 hour. RESULTS: Of 680 patients, 438 (64%) were enrolled on the basis of an ABC score ≥2 and 242 (36% by PG when the ABC score was <2). Patients enrolled by PG were older (median, 44; interquartile range [IQR], 28-59; p < 0.001), more likely to be White (70.3% vs. 60.3%, p = 0.014), and more likely to have been injured by blunt mechanisms (77.3% vs. 37.2%, p < 0.001). They were also less hypotensive and less tachycardic than patients enrolled by ABC score (both p < 0.001). The groups had similar Injury Severity Scores in the ABC ≥ 2 and PG groups (26 and 27, respectively) and were equally represented (49.1% and 50.8%, respectively) in the 1:1:1 treatment arm. There were no significant differences between the ABC score and PG groups for mortality at any point. Time to hemostasis (108 for patients enrolled on basis of Gestalt, vs. 100 minutes for patients enrolled on basis of ABC score), and the proportion of patients requiring a massive transfusion (>10 units/24 hours) (44.2% vs. 47.3%), or meeting the critical administration threshold (>3 unit/1 hour) (84.7% vs. 89.5%) were similar ( p = 0.071). CONCLUSION: Early identification of trauma patients likely to require a massive transfusion is important for clinical care, resource use, and selection of patients for clinical trials. Patients enrolled in the PROPPR trial based on PG when the ABC score was <2 represented 36% of the patients and had identical outcomes to those enrolled on the basis of an ABC score of ≥2. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Vein-first vs. artery-first robotic lobectomy outcomes in non-small cell lung cancer.

Background: Data remains limited as to whether the order of pulmonary vessel division during performance of a lobectomy for non-small cell lung cancer (NSCLC) affects survival outcomes. Some authors have suggested that ligation of the pulmonary veins should be conducted first in order to minimize the spread of tumor cells secondary to manipulation of the lung. This study examines whether there is a difference in outcomes between patients who undergo robotic lobectomies for NSCLC using a vein-first (V-first) vs. artery-first (A-first) technique. Methods: A retrospective review of electronic medical record data was performed for patients who underwent robotic lobectomies from January 2013 to May 2019. Patients were separated into two groups based on the sequence in which the pulmonary vessels were divided: V-first or A-first. Baseline characteristics and postoperative events were recorded and compared between groups using Chi-squared and Student's t-tests. Kaplan-Meier survival curves for overall and recurrence-free survival were constructed and compared with log-rank tests. Results: A total of 374 patients were identified: 94 V-first and 280 A-first patients. There was no significant difference between the V-first and A-first groups with regards to postoperative complications, length of stay, recurrence-free survival, or overall survival. Conclusions: Our study suggests that choosing a V-first vs. A-first technique for a robotic lobectomy does not significantly impact overall survival or cancer recurrence for patients with NSCLC. Further studies are needed to evaluate whether the order of pulmonary vessel resection affects outcomes for patients with NSCLC.

Changes in Imaging Utilization for Primary Hyperparathyroidism.

INTRODUCTION: Primary hyperparathyroidism is now largely managed surgically via minimally invasive techniques. This shift was aided by preoperative imaging, which saw drastic increases in utilization in the 1990s. Since then, it is unclear how the role of preoperative imaging has changed with regard to surgical management of primary hyperparathyroidism. This study aims to describe the trend in preoperative localization techniques for surgical management of primary hyperparathyroidism using career data from two endocrine surgeons over the last 20 years. METHODS: Parathyroid case data was obtained from two endocrine surgeons spanning two institutions from 2000-2018. Demographic and clinical data was obtained for each patient at the time of surgery, including record of any preoperative imaging performed. Data was analyzed temporally using four 5-year periods to evaluate changes in imaging utilization over time. RESULTS: 1734 patients were identified who underwent parathyroidectomy for primary hyperparathyroidism. Mean age of the cohort was 60 years (range 10-94) with 78% being female. Overall, we identified a significant decrease in imaging utilization over the time periods (see table, P < .05). Ultrasound and CT use increased, while frequency of sestamibi and thallium-technetium scans decreased. Length of stay was also noted to decrease over time. There was no significant difference in cure rates between the four time periods, though recurrence was found to decrease over time. CONCLUSION: The rates of preoperative imaging and length of stay decreased over time for surgical management of primary hyperparathyroidism. Despite the decrease in imaging, cure rates have appeared to remain the same.

Pediatric traumatic hemorrhagic shock consensus conference recommendations.

ABSTRACT: Hemorrhagic shock in pediatric trauma patients remains a challenging yet preventable cause of death. There is little high-quality evidence available to guide specific aspects of hemorrhage control and specific resuscitation practices in this population. We sought to generate clinical recommendations, expert consensus, and good practice statements to aid providers in care for these difficult patients.The Pediatric Traumatic Hemorrhagic Shock Consensus Conference process included systematic reviews related to six subtopics and one consensus meeting. A panel of 16 consensus multidisciplinary committee members evaluated the literature related to 6 specific topics: (1) blood products and fluid resuscitation for hemostatic resuscitation, (2) utilization of prehospital blood products, (3) use of hemostatic adjuncts, (4) tourniquet use, (5) prehospital airway and blood pressure management, and (6) conventional coagulation tests or thromboelastography-guided resuscitation. A total of 21 recommendations are detailed in this article: 2 clinical recommendations, 14 expert consensus statements, and 5 good practice statements. The statement, the panel's voting outcome, and the rationale for each statement intend to give pediatric trauma providers the latest evidence and guidance to care for pediatric trauma patients experiencing hemorrhagic shock. With a broad multidisciplinary representation, the Pediatric Traumatic Hemorrhagic Shock Consensus Conference systematically evaluated the literature and developed clinical recommendations, expert consensus, and good practice statements concerning topics in traumatically injured pediatric patients with hemorrhagic shock.

Balancing enrollment and mortality in hemorrhage control trials: A secondary analysis of the PROPPR trial.

BACKGROUND: Designing clinical trials on hemorrhage control requires carefully balancing the need for high enrollment numbers with the need of focusing on the sickest patients. The Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial enrolled patients within 2 hours of arrival to the emergency department for a trial of injured patients at risk for massive transfusion. We conducted a secondary analysis to determine how time-to-randomization affected patient outcomes and the balance between enrollment and mortality. METHODS: Patients from the Pragmatic Randomized Optimal Platelet and Plasma Ratios trial were compared based on 30-minute time to randomization intervals. Outcomes included 24-hour and 30-day mortality, time to hemostasis, adverse events, and operative procedures. Additional analyses were conducted based on treatment arm allocation, mechanism of injury, and variation in start time (arrival vs. randomization). RESULTS: Randomization within 30 minutes of arrival was associated with higher injury severity (median Injury Severity Score, 29 vs. 26 overall; p < 0.01), lower systolic blood pressure (median, 91 vs. 102 mm Hg overall; p < 0.01), and increased penetrating mechanism (50% vs. 47% overall; p < 0.01). Faster time-to-randomization was associated with increased 24-hour (20% for 0- to 30 minute entry, 9% for 31-minute to 60-minute entry, 10% for 61-minute to 90-minute entry, 0% for 91-minute to 120-minute entry; p < 0.01) and 30-day mortality (p < 0.01). There were no significant associations between time-to-randomization and adverse event occurrence, operative interventions, or time to hemostasis. CONCLUSION: Increasing time to randomization in this large multicenter randomized trial was associated with increased survival. Fastest randomization (within 0-30 minutes) was associated with highest 24-hour and 30-day mortality, but only 57% of patients were enrolled within this timeframe. Only 3% of patients were enrolled within the last 30-minute window (91-120 minutes), with none of them dying within the first 24 hours. For a more optimal balance between enrollment and mortality, investigators should consider shortening the time to randomization when planning future clinical trials of hemorrhage control interventions.

Imaging analysis of ischemic strokes due to blunt cerebrovascular injury.

BACKGROUND: The timing of stroke onset among patients with blunt cerebrovascular injury (BCVI) is not well understood. All blunt trauma patients at our institution undergo a screening computed tomographic angiography (CTA) of the neck. Most patients with CTA evidence of BCVI are treated with aspirin, and all patients with clinical evidence of stroke are treated with aspirin and undergo magnetic resonance imaging (MRI) of the brain. We conducted a retrospective review to determine the incidence of stroke upon admission and following admission. METHODS: All neck CTAs and head MRIs obtained in blunt trauma patients were reviewed from August 2017 to August 2019. All CTAs that were interpreted as showing BCVI were individually reviewed to confirm the diagnosis of BCVI. Stroke was defined as brain MRI evidence of new ischemic lesions, and each MRI was reviewed to identify the brain territory affected. We extracted the time to aspirin administration and the timing of stroke onset from patients' electronic health records. RESULTS: Of the 6,849 blunt trauma patients, 479 (7.0%) had BCVIs. Twenty-four patients (5.0%) with BCVI had a stroke on admission. Twelve (2.6%) of the remaining 455 patients subsequently had a stroke during their hospitalization. The incidence of stroke among patients with BCVI was 7.5%; 2.6% were potentially preventable. Only 5 of the 12 patients received aspirin before the onset of stroke symptoms. All 36 patients with BCVI and stroke had thromboembolic lesions in the territory supplied by an injured vessel. CONCLUSION: With universal screening, CTA evidence of BCVI is common among blunt trauma patients. Although acute stroke is also relatively common in this population, two thirds of strokes are already evident on admission. One third of BCVI-related strokes occur after admission and often relatively early, necessitating rapid commencement of preventative treatment. Further studies are required to demonstrate the value of antithrombotic administration in preventing stroke in BCVI patients. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level IV.

Non-Governmental Organizations Delivering Global Cardiac Surgical Care: A Quantitative Impact Assessment.

In low- and middle-income countries (LMICs), 93% of the population lacks safe, timely, and affordable access to cardiac surgical care when needed. As countries slowly build or expand local, independent cardiac centers, non-governmental organizations (NGOs) partially bridge the gap in cardiac surgical care delivery in LMICs. However, little is known about the current scope of cardiac NGOs. Here, we perform an analysis of active NGOs involved with the delivery of cardiac surgical services in LMICs or for patients from LMICs. Cardiac surgery NGOs were identified from medical literature, established NGO databases, and Google Scholar searches. The search was performed between December 2019 and May 2020. NGOs whose websites were not updated or described missions or projects taking place no later than 2015 were considered inactive. Eighty-six NGOs are actively providing cardiac surgery services in LMICs or treating patients from LMICs. Five NGOs performed adult cardiac surgery only, 56 performed pediatric cardiac surgery only, and 25 performed both adult and pediatric cardiac surgery. NGOs originated from 23 different countries and were operational in a total of 111 countries, 96 of them being LMICs. Fifty-three NGOs reported data on annual surgical volume, of which half performed less than 50 operations per year. NGOs effectively address the burden of cardiac surgical disease in LMICs and contribute to local capacity-building. Increased, more detailed, and standardized reporting of the impact and outcomes of NGOs is necessary to better understand annual cardiac surgical volume and to support local centers working towards independent services.

Resident self-assessment of common endocrine procedures.

BACKGROUND: General surgery residency graduates are expected to be proficient in straightforward endocrine operations. This study aimed to elucidate residents' self-assessment of their ability to perform common endocrine procedures. METHODS: A fourteen-question survey was emailed to general surgery residents from seven U.S. residency programs regarding their self-assessed ability to perform each step of a straightforward thyroidectomy and parathyroidectomy. Demographics and perceived ability to perform the various procedures were collected. RESULTS: A minority of respondents (17, 27.9%) agreed they could complete a straightforward thyroidectomy for benign disease, with only 11.7% (n = 7) agreeing they could complete a straightforward thyroidectomy for malignant disease. 26.2% (n = 16) of respondents agreed they could complete a straightforward parathyroidectomy. Completed number of cases was significantly associated with greater self-assessed ability to perform the endocrine operations (p = 0.02). CONCLUSIONS: Most general surgery residents surveyed did not feel capable of performing common, straightforward endocrine procedures. Although confidence in operative ability increased with PGY-level and number of cases completed, the majority of PGY-5 residents still did not feel able to perform a thyroidectomy for malignant disease unassisted.

Understanding the geography of trauma: Combining spatial analysis and funnel plots to create comprehensive spatial injury profiles.

BACKGROUND: Understanding geographic patterns of injury is essential to operating an effective trauma system and targeting injury prevention. Choropleth maps are helpful in showing spatial relationships but are unable to provide estimates of spread or degrees of confidence. Funnel plots overcome this issue and are a recommended graphical aid for comparisons that allow quantification of precision. The purpose of this project was to demonstrate the complementary roles of choropleth maps and funnel plots in providing a thorough representation of geographic trauma data. METHODS: This is a retrospective analysis of emergency medical service transport data of adult patients in Alabama from July 2015 to June 2020. Choropleth maps of case volume and observed-to-expected ratios of incidence were created using US Census Bureau data. Funnel plots were created to relate incidence rate to county population. Subgroup analyses included patients with critical physiology, penetrating, blunt, and burn injuries. RESULTS: We identified 65,247 trauma incidents during the study period. The overall statewide incidence rate was 133 per 10,000 persons. The highest number of incidents occurred in the most populous counties (Jefferson, 10,768; Mobile, 5,642). Choropleth maps for overall incidence and subgroups highlighted that spatial distribution of overall case volume and observed-to-expected ratios are not always congruent. Funnel plots identified possible and probable outliers, and revealed skewed or otherwise unique patterns among injury subgroups. CONCLUSION: This study demonstrates the complementarity of choropleth maps and funnel plots in describing trauma patterns. Comprehensive geospatial analyses may help guide a data-driven approach to trauma system optimization and injury prevention. Combining maps of case counts, incidence, and funnel plots helps to not only identify geographic trends in data but also quantify outliers and display how far results fall outside the expected range. The combination of these tools provides a more comprehensive geospatial analysis than either tool could provide on its own. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level IV.

Evaluation of Injury Recidivism Using the Electronic Medical Record.

BACKGROUND: Traumatic injuries remain one of the leading causes of death in the United States. Patients who survive traumatic injuries but return to the emergency department with repeat injuries are said to suffer from injury recidivism. Numerous studies have described trends in injury recidivism using trauma registry and survey data. To our knowledge, no prior study has leveraged electronic medical record (EMR) data to characterize injury recidivism. The EMR is potentially more comprehensive as it contains details of patients who visited the emergency department after injury but did not meet the criteria for inclusion in the trauma registry. Such injuries could be predictive of future recidivism. We therefore aimed to describe patterns of injury recidivism seen at a Level 1 trauma center using the EMR. METHODS: A retrospective review was conducted of all injury-related encounters between January 2016 and December 2019. Manual review was conducted of all recidivistic encounters with < 11 months between encounters to ensure the recidivistic encounter was not a sequela of the index visit. A general estimating equation logistic regression adjusted for age, race, sex, and insurance payor, estimated odds ratios (ORs) and 95% confidence intervals (CIs) for the association between injury mechanism and odds of recidivistic encounter. RESULTS: A total of 20,566 index encounters was included during the study period. Of the 20,566 encounters, 7.6% (n = 1570) had a recidivistic encounter during the study period, half of which (n = 781) occurred within the first year of the index encounter. An over two-fold increased odds of recidivism was observed for blunt assault encounters (OR 2.53, 95% CI 2.03-3.15) and unintentional falls (OR 2.10, 95% CI 1.76-2.52). For both mechanisms, this increase was observed across the three years following the index encounter. CONCLUSIONS: Our study found that patients with assault injuries have the highest odds of injury recidivism and assault-related recidivistic encounters. These results demonstrate the feasibility and utility of incorporating EMR data, and suggest that the development of targeted interventions focused on mitigating assault injuries, such as hospital-based violence intervention programs, should be considered in our region.

Universal screening for blunt cerebrovascular injury.

BACKGROUND: Blunt cerebrovascular injury (BCVI) can result in thromboembolic stroke. Many trauma centers selectively screen patients with cervical computed tomographic angiography (CTA) based on clinical criteria. In 2016, our institution adopted universal screening for BCVI for all blunt trauma patients. The aim of this study was to accurately determine the incidence of BCVI and to evaluate the diagnostic performance of the Denver criteria (DC), expanded Denver criteria (eDC), and Memphis criteria (MC) in selecting patients for screening. METHODS: Retrospective cohort study of adult (≥16 years) blunt trauma patients who presented to the Level I trauma center at University of Alabama at Birmingham. We reviewed all CTA reports and selected CTA images to obtain the true incidence rate of BCVI. We then evaluated the diagnostic performance of the DC, eDC, and MC. RESULTS: A total of 6,800 patients who had suffered blunt trauma were evaluated, of whom 6,287 (92.5%) had a neck CTA. Of these, 480 (7.6%) patients had CTA evidence of BCVI. The eDC identified the most BCVI cases (sensitivity 74.7%) but had the lowest positive predictive value (14.6%). The DC and MC had slightly greater positive predictive values (19.6% and 20.6%, respectively) and had the highest diagnostic ability in terms of likelihood ratio (2.8 and 2.9) but had low sensitivity (57.5% and 47.3%). Consequently, if relying on the traditional screening criteria, the DC, eDC, and MC would have respectively resulted in 42.5%, 25.3%, and 52.7% of patients with BCVI identified by universal screening not receiving a neck CTA to screen for BCVI. CONCLUSION: Blunt cerebrovascular injury is even more common than previously thought. The diagnostic performance of selective clinical screening criteria is poor. Consideration should be given to the implementation of universal screening for BCVI using neck CTA in all blunt trauma patients. LEVEL OF EVIDENCE: Diagnostic, level III.

Cross-Sectional Analysis of Global Surgery Opportunities Among General Surgery Residency Programs.

BACKGROUND: Global surgery is a rising field within academic surgery. With the publication of recent landmark papers highlighting the need for increased global efforts to combat surgical disease, many general surgery residents seek opportunities to gain clinical, research, and educational experience related to global surgery during residency. This study aims to quantify the global surgery opportunities that are publicly available to residents training in Accreditation Council for Graduate Medical Education (ACGME)-accredited general surgery programs. METHODS: The websites of all ACGME-accredited general surgery residency programs were surveyed for mention of global surgery training opportunities. Each opportunity was recorded in a database and categorized based on type. Recorded categories include international clinical rotations, international surgical research opportunities, and formal tracks or training pathways for global surgery. RESULTS: Of the 299 ACGME-accredited general surgery training programs, 52 (17%) mention some form of international surgical opportunity on their website. Among these programs, 11 (21%) note both clinical and research opportunities, 28 (54%) mention only clinical opportunities, and 13 (25%) list only research opportunities. The large majority of global surgery opportunities were based in training programs at academic medical centers (n = 50, 96%). There was no significant difference in the percentage of global surgery programs when evaluated by program region (p = 0.154) CONCLUSIONS: Few general surgery residency programs mention international training opportunities on their program websites. For those programs that do offer global surgery opportunities, these are typically international rotations offered as electives for upper-level residents. Expanding access to global surgery opportunities may be beneficial to meet the desires of residents wishing to pursue academic global surgery.

What is global surgery? Identifying misconceptions among health professionals.

BACKGROUND: Global surgery has emerged as a new field within academic surgery. Despite attempts to provide a common definition, it is unclear whether health professionals understand what is meant by the term "global surgery." This study aims to characterize current understanding of global surgery among healthcare workers. METHODS: One hundred medical students, residents, physicians, nurses, and allied health professionals were interviewed on their perceptions of global surgery using a six-question qualitative survey. Responses were coded and analyzed for common themes. RESULTS: Sixty-one percent of participants did not know the meaning of global surgery. Those under age 40 were more likely to relay an accurate definition. Of participants with knowledge of global surgery, 44% had previous exposure to global health and 85% expressed interest in global health or surgery. CONCLUSIONS: Although often used in academic surgical settings, the term "global surgery" is not well-understood among health professionals. There is no clear consensus on what it means to be a global surgeon or what constitutes a successful career in global surgery.
