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.

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.

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.

Analysis of Outcomes in Adolescents and Young Adults With Pilonidal Disease.

Purpose: Numerous definitive surgical techniques exist for the treatment of pilonidal disease with varied recurrence rates and wound complications. Due to the wide array of techniques and lack of consensus on the best approach, we proposed to study our experience treating pilonidal disease in adolescents and young adults. Methods: A retrospective analysis was conducted of patients 10-24 years old treated at a tertiary medical center from 2011 to 2016. Data including demographics, management, and outcomes were collected and analyzed. Primary outcome was recurrence of disease. Results: One hundred and thirty three patients with pilonidal disease underwent operative management. Fifty one percent underwent primary closure and 49% healed by secondary intention with no significant difference in recurrence rates (primary 18%, secondary 11%; p = 0.3245). Secondary healing patients had significantly lower wound complication rates (primary 51%, secondary 23%; p = 0.0012). After accounting for sex, race, weight, and operative technique, age was predictive of disease recurrence with an adjusted odds ratio (OR) of 0.706 (0.560-0.888; p = 0.003). Age and sex were both predictive of wound complications. Older patients had decreased risk of wound complication (adjusted OR 0.806, 95% CI 0.684-0.951; p = 0.0105), and male patients had increased risk of wound complication (adjusted OR 2.902, 95% CI 1.001-8.409; p = 0.0497). Conclusion: In summary, there is no significant difference in the recurrence rates between operative techniques for pilonidal disease. Older patients have decreased risk of recurrence following intervention. Wound complication rates are lower in patients undergoing secondary healing, though this may be better explained by differences in age and sex. Additional research investigating newer, minimally-invasive techniques needs to be pursued.

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.

Mapping the Informed Consent Process for Left Ventricular Assist Devices.

Ethical, practical, and medical challenges affect decisions about left ventricular assist device (LVAD) implantation. The informed consent document (IC-Doc) is integral to the decision-making process and structures informed consent conversations. The objective of this study was to analyze IC-Docs to identify the information patients and their families receive about LVAD implantation to create a model IC-Doc. We requested IC-Doc for LVAD implantation from LVAD programs in the United States. We analyzed them in three areas: medical and technical content, patient knowledge gaps, and syntax. Nineteen IC-Docs representing all United Network of Organ Sharing regions were included. Seventeen (89.5%) mentioned the indications for LVAD implantation (bridge to transplant or destination therapy), and six indicated which category applied to the patient. Palliative care was mentioned as an alternative in nine (47.4%); no IC-Doc discussed nonsurgical palliative care. Eight forms (42.1%) specifically mentioned turning off the LVAD. Eighteen forms mention general bleeding, and four referred to long-term gastrointestinal bleeding. Two IC-Docs addressed driveline infections. One form was written at an 8th grade reading level. There is wide variation in LVAD IC-Docs and omission of some benefits and risks. We have written an IC-Doc that meets criteria for disclosure, fills many knowledge gaps, and has an acceptable readability score.
