Adrenalectomy approach and outcomes according to surgeon volume

BACKGROUND

This study assessed the relationship between surgeon volume, operative management, and resource utilization in adrenalectomy.

METHODS

Isolated adrenalectomies performed within our health system were identified (2016-2021). High-volume surgeons were defined as those performing ≥6 cases/year. Outcomes included indication for surgery, perioperative outcomes, and costs.

RESULTS

Of 476 adrenalectomies, high-volume surgeons (n ​= ​3) performed 394, while low-volume surgeons (n ​= ​12) performed 82. High-volume surgeons more frequently operated for pheochromocytoma (19% vs. 16%, p ​< ​0.001) and less frequently for metastasis (6.4% vs. 23%, p ​< ​0.001), more frequently used laparoscopy (95% vs. 80%, p ​< ​0.001), and had lower operative supply costs ($1387 vs. $1,636, p ​= ​0.037). Additionally, laparoscopic adrenalectomy was associated with shorter length of stay (-3.43 days, p ​< ​0.001), lower hospitalization costs (-$72,417, p ​< ​0.001), and increased likelihood of discharge to home (OR 17.03, p ​= ​0.008).

CONCLUSIONS

High-volume surgeons more often resect primary adrenal pathology and utilize laparoscopy. Laparoscopic adrenalectomy is, in turn, associated with decreased healthcare resource utilization.

Predictive Risk Score for Postparathyroidectomy Hungry Bone Syndrome in Patients With Secondary Hyperparathyroidism

PURPOSE

Secondary hyperparathyroidism (SHPT) frequently affects patients with end-stage renal disease. Hungry bone syndrome (HBS) is a common complication among patients who undergo parathyroidectomy for SHPT and may cause prolonged hospitalization or require intensive care. The objective of this study is to develop a scoring system to stratify patients according to their risk of developing HBS.

METHODS

A retrospective cohort study was performed using the US Renal Data System (2010-2021). Univariable and multivariable logistic regression models were developed and weighted β-coefficients from the multivariable model were used to construct a risk score for the development of HBS. Positive and negative predictive values were assessed.

RESULTS

Of 17 074 patients who underwent parathyroidectomy for SHPT, 19.4% developed HBS. Intensive care unit admission was more common in patients who developed HBS (33.5% vs 24.6%, P < .001). On multivariable logistic regression analysis, younger age, renal osteodystrophy, longer duration of dialysis, longer duration of kidney transplant, and higher Elixhauser score were significantly associated with HBS. A risk score based on these clinical factors was developed, with a total of 6 possible points. Rates of HBS ranged from 8% in patients with 0 points to 44% in patients with 6 points. The risk score had a poor positive predictive value (20.3%) but excellent negative predictive value (89.3%) for HBS.

CONCLUSION

We developed a weighted risk score that effectively stratifies patients by risk for developing HBS after parathyroidectomy. This tool can be used to counsel patients and to identify patients who may not require postoperative hospitalization.

Sex differences and racial/ethnic disparities in the presentation and treatment of medullary thyroid cancer

BACKGROUND

This study assessed for disparities in the presentation and management of medullary thyroid cancer (MTC).

METHODS

Patients with MTC (2010-2020) were identified from the National Cancer Database. Differences in disease presentation and likelihood of guideline-concordant surgical management (total thyroidectomy and resection of ≥1 lymph node) were assessed by sex and race/ethnicity.

RESULTS

Of 6154 patients, 68.2% underwent guideline-concordant surgery. Tumors >4 ​cm were more likely in men (vs. women: OR 2.47, p ​< ​0.001) and Hispanic patients (vs. White patients: OR 1.52, p ​= ​0.001). Non-White patients were more likely to have distant metastases (Black: OR 1.63, p ​= ​0.002; Hispanic: OR 1.44, p ​= ​0.038) and experienced longer time to surgery (Black: HR 0.66, p ​< ​0.001; Hispanic: HR 0.71, p ​< ​0.001). Black patients were less likely to undergo guideline-concordant surgery (OR 0.70, p ​= ​0.022).

CONCLUSIONS

Male and non-White patients with MTC more frequently present with advanced disease, and Black patients are less likely to undergo guideline-concordant surgery.

Defining Optimal Management of Non-metastatic Adrenocortical Carcinoma

BACKGROUND

Adrenocortical carcinoma (ACC) is an aggressive, deadly malignancy. Resection remains the primary treatment; however, there is conflicting evidence regarding the optimal approach to and extent of surgery and the role of adjuvant therapy. We evaluated the impact of surgical technique and adjuvant therapies on survival in non-metastatic ACC.

METHODS

We performed a retrospective cohort study of subjects who underwent surgery for non-metastatic ACC between 2010 and 2019 utilizing the National Cancer Database. The primary outcome was overall survival. Cox proportional hazards models were developed to identify associations between clinical and treatment characteristics and survival.

RESULTS

Overall, 1175 subjects were included. Their mean age was 54 ± 15 years, and 62% of patients were female. 67% of procedures were performed via the open approach, 22% involved multi-organ resection, and 26% included lymphadenectomy. Median survival was 77.1 months. Age (hazard ratio [HR] 1.019; p < 0.001), advanced stage (stage III HR 2.421; p < 0.001), laparoscopic approach (HR 1.329; p = 0.010), and positive margins (HR 1.587; p < 0.001) were negatively associated with survival, while extent of resection (HR 1.189; p = 0.140) and lymphadenectomy (HR 1.039; p = 0.759) had no association. Stratified by stage, laparoscopic resection was only associated with worse survival in stage III disease (HR 1.548; p = 0.007). Chemoradiation was only associated with improved survival in patients with positive resection margins (HR 0.475; p = 0.004).

CONCLUSION

Tumor biology and surgical margins are the primary determinants of survival in non-metastatic ACC. Surgical extent and lymphadenectomy are not associated with overall survival. In advanced disease, the open approach is associated with improved survival.

Surgical Management of Metastatic Adrenocortical Carcinoma

Introduction

Adrenocortical carcinoma (ACC) is a notoriously aggressive cancer with a dismal prognosis, especially for patients with metastatic disease. Metastatic ACC is classically a contraindication to operative management. Here, we evaluate the impact of primary tumor resection and metastasectomy on survival in metastatic ACC.

Methods

We performed a retrospective cohort study of patients with metastatic ACC (2010-2019) utilizing the National Cancer Database. The primary outcome was overall survival (OS). Cox proportional hazards models were developed to evaluate the associations between surgical management and survival. Propensity score matching (PSM) was utilized to account for selection bias in receipt of surgery.

Results

Of 976 subjects with metastatic ACC, 38% underwent surgical management. Median OS across all patients was 7.6 months. On multivariable Cox proportional hazards regression, primary tumor resection alone (HR: 0.523; p<0.001) and primary resection with metastasectomy (HR: 0.372; p<0.001) were significantly associated with improved OS. Metastasectomy alone had no association with OS (HR: 0.909; p=0.740). Primary resection with metastasectomy was associated with improved OS over resection of the primary tumor alone (HR: 0.636; p=0.018). After PSM, resection of the primary tumor alone remained associated with improved OS (HR 0.593; p<0.001), and metastasectomy alone had no survival benefit (HR 0.709; p=0.196) compared with non-operative management; combined resection was associated with improved OS over primary tumor resection alone (HR 0.575, p=0.008).

Conclusion

In metastatic ACC, patients may benefit from primary tumor resection alone or in combination with metastasectomy, however further research is required to facilitate appropriate patient selection.

Development of a risk-prediction model for primary aldosteronism in veterans with hypertension

BACKGROUND

Rates of screening for primary aldosteronism in patients who meet the criteria are exceedingly low (1%-3%). To help clinicians prioritize screening in patients most likely to benefit, we developed a risk-prediction model.

METHODS

Using national Veterans Health Administration data, we identified patients who met the criteria for primary aldosteronism screening between 2000 and 2019. We performed multivariable logistic regression to identify characteristics associated with positive primary aldosteronism testing before generating a risk-scoring system based on the coefficients (0< β < 0.5 = 1 pt, 0.5 ≤ β < 1 = 2 pts, 1 ≤ β < 1.5 = 3 pts) and then tested the system performance using an internal validation cohort.

RESULTS

We identified 502,190 patients who met primary aldosteronism screening criteria, of whom 1.6% were screened and 15% tested positive. Based on the regression model, we generated a risk-scoring system based on a total of 9 possible points in which age under 50, absence of smoking history, and resistant hypertension each scored 1 point; elevated serum sodium 2 points; and hypokalemia 3 points. Rates of positive screening increased with risk score, with 5.6% to 6.7% of those scoring 0 points testing positive; 7.9% to 9.0% 1 point; 8.6% to 10% 2 points; 13% to 14% 3 points; 21% 4 points; 22% to 38% 5 points; 27% to 38% 6 points; 42% to 49% 7 points; and 50% to 51% ≥8 points.

CONCLUSION

In hypertensive patients who meet the criteria for primary aldosteronism screening, rates of positive screening range from 5.6% to 51%. Use of our risk-predication model incorporating these factors can identify patients most likely to benefit from testing.

Disparities in Presentation, Treatment, and Survival in Anaplastic Thyroid Cancer

BACKGROUND

Disparities have been previously described in the presentation, management, and outcomes of other thyroid cancer subtypes; however, it is unclear whether such disparities exist in anaplastic thyroid cancer (ATC).

METHODS

We identified patients with ATC from the National Cancer Database (2004-2020). The primary outcomes were receipt of surgery, chemotherapy, and radiation. The secondary outcome was 1-year survival. Multivariable logistic and Cox proportional hazards regressions were used to assess the associations between sex, race/ethnicity, and the outcomes.

RESULTS

Among 5359 patients included, 58% were female, and 80% were non-Hispanic white. Median tumor size was larger in males than females (6.5 vs. 6.0 cm; p < 0.001) and in patients with minority race/ethnicity than in white patients (6.5 vs. 6.0 cm; p < 0.001). After controlling for tumor size and metastatic disease, female patients were more likely to undergo surgical resection (odds ratio [OR]: 1.20; p = 0.016) but less likely to undergo chemotherapy (OR: 0.72; p < 0.001) and radiation (OR: 0.76; p < 0.001) compared with males. Additionally, patients from minority racial/ethnic backgrounds were less likely to undergo chemotherapy (OR: 0.69; p < 0.001) and radiation (OR: 0.71; p < 0.001) than white patients. Overall, unadjusted, 1-year survival was 23%, with differences in treatment receipt accounting for small but significant differences in survival between groups.

CONCLUSIONS

There are disparities in the presentation and treatment of ATC by sex and race/ethnicity that likely reflect differences in access to care as well as patient and provider preferences. While survival is similarly poor across groups, the changing landscape of treatments for ATC warrants efforts to address the potential for exacerbation of disparities.

Making the news: Victim characteristics associated with media reporting on firearm injury

Firearm injury is a public health crisis in the United States. Selective media coverage may contribute to incomplete public understanding of firearm injury. To better understand how firearm injury is communicated to the public, we analyzed media coverage of intentional, interpersonal shootings in 3 U.S. cities. We hypothesized that multiple shootings and fatal shootings would be more likely to make the news, as would shootings affecting children, women, and white individuals. We compared police department data on shootings to media reports drawn from the Gun Violence Archive (GVA) for 2017 in Philadelphia, PA, Rochester, NY, and Cincinnati, OH. GVA reports were matched to police data by shooting date, location, victim age, and gender. Matched victims were compared to unmatched using chi2 tests for categorical variables and Kruskal Wallis tests for continuous variables. Philadelphia police reported 1216 firearm assault victims; Cincinnati police reported 407; and Rochester police reported 178. News reports covered 562 (46.2%), 222 (54.6%), and 116 (65.2%) victims, respectively. Fatal shootings were more often reported as were shootings involving multiple victims or women. Half of shooting victims did not make the news. Selective reporting likely limits awareness of the public health impact of firearm injury. Researchers and policy makers should work with journalists and editors to improve the quantity and content of reporting on firearm injury.

Multiple Complications in Emergency Surgery : Identifying Risk Factors for Failure-to-Rescue

BACKGROUND

While the use of the failure-to-rescue (FTR) metric, or death after complication, has expanded beyond elective surgery to emergency general surgery (EGS), little is known about the trajectories patients take from index complication to death.

METHODS

We conducted a retrospective cohort study of EGS operations using the National Surgical Quality Improvement Project (NSQIP) dataset, 2011-2017. 16 major complications were categorized as infectious, respiratory, thrombotic, cardiac, renal, neurologic, or technical. We tabulated common combinations of complications. We then use logistic regression analyses to test the hypotheses that (1) increase in the number and frequency of complications would yield higher FTR rates and (2) secondary complications that span a greater number of organ systems or mechanisms carry a greater associated FTR risk.

RESULTS

Of 329 183 EGS patients, 69 832 (21.2%) experienced at least 1 complication. Of the 11 195 patients who died following complication (16.0%), 8205 (63.4%) suffered more than 1 complication. Multivariable regression analyses revealed an association between the number of complications and mortality risk (odds ratio [OR] 2.37 for 2 complications vs 1, P < .001). There was a similar increase in mortality with increased complication accrual rate (OR 3.29 for 0.2-0.4 complications/day vs <0.2, P < .001). Increasing the number of types of complication were similarly associated with mortality risk.

DISCUSSION

While past FTR analyses have focused primarily on index complication, a broader consideration of ensuing trajectory may enable identification of high-risk cohorts. Efforts to reduce mortality in EGS should focus on attention to those who suffer a complication to prevent a cascade of downstream complications culminating in death.

How Should Schools Respond to Learners' Demands for Global Health Training?

In the past decade, more students than ever entered medical school with the desire, if not the expectation, of participating in meaningful global health experiences. Schools must now weigh benefits to students of global experiences against burdens of students' learning experiences on institutions and individuals with whom schools partner. Most often, global health training is done as offsite immersion rotations in research or clinical settings. This article explores ethical dimensions of expanding global health offerings while respecting local partners' goals by focusing on the experience of the University of Pennsylvania's global health training programs.
