Consolidation trends in vascular surgery.

BACKGROUND: Practice consolidation by vertical and horizontal integration is a growing trend in surgery. Practice consolidation has not been previously examined in vascular surgery. METHODS: The Medicare Provider Enrollment, Chain, and Ownership System data were used to identify vascular providers and vascular surgery practices in the United States in 2015 and 2020. Practices were categorized as solo (1 surgeon), small (2), medium (3-5), and large (≥6). The number of providers and the number of practices in each size group were determined. The Hirfendahl-Hirshman index (HHI), a measure of market consolidation, was calculated. Provider count, practice size, and HHI were additionally analyzed by urban and rural regions. All values were calculated for each time point and compared. RESULTS: Vascular providers increased in number from 2929 to 3154 (7.7%) from 2015 to 2020. The number of practices decreased from 1351 to 1090 (19.3%). The number of large practices increased by 49.4%; the number of small or solo practices decreased by 42.1%. The mean HHI increased from 0.486 in 2015 to 0.498 in 2020. Both urban and rural regions had a decrease in solo practices (43.3% and 2.3%, respectively) and an increase in HHI (from 0.499 to 0.509 and 0.793 to 0.818, respectively). All changes were statistically significant. CONCLUSIONS: From 2015 to 2020, there is a trend toward vascular providers working in larger practice groups and a corresponding increase in measures of market consolidation.

Adrenalectomy Outcome Variations Across Different Functional Adrenal Tumors.

INTRODUCTION: Adrenalectomy generally has favorable outcomes. It is unknown if patients with functional adrenal tumors experience different clinical outcomes than those with benign adrenal tumors, due to the presence of comorbid conditions secondary to the functional tumor. We investigated outcomes following open and laparoscopic adrenalectomy for benign nonfunctional (BNF) versus functional adrenal masses. METHODS: Patients undergoing adrenalectomy were identified in the 2015-2020 National Surgical Quality Improvement Program database, then categorized as BNF, hyperaldosteronism, hypercortisolism, and pheochromocytoma. The primary outcome of interest was 30-d morbidity and secondary outcomes included 30-d mortality, 30-d readmission, and postoperative length of stay (LOS). Subgroup analysis was performed based upon surgical approach. Univariate analysis was performed, followed by multivariable logistic regression for individual outcomes that differed significantly between patients with BNF and functional neoplasm, factoring in patient demographics and operative approach with statistical significance on univariate analysis. Descriptive statistics and outcomes were analyzed using Pearson's χ2 test and Mann-Whitney U-test as appropriate. RESULTS: There were 3291 patients with BNF while 484 had hyperaldosteronism, 263 hypercortisolism, and 46 pheochromocytomas. Within the laparoscopic group of 3615 (88.5%) of adrenalectomy patients, compared to BNF patients, patients with hyperaldosteronism had lower rates of postoperative morbidity (1.9% versus 5.2%, P < 0.001) and shorter LOS (1 d, interquartile range (IQR) [1-1] versus 1d IQR [1-2], P = 0.003); these persisted on multivariate analysis (OR 0.32, 95% confidence interval [CI] 0.14-0.74 and odds ratio 0.47, 95% CI 0.36-0.60, P < 0.001). Patients with hypercortisolism had higher morbidity (7.3% versus 5.2%, P < 0.001), 30-d readmission rates (5.3% versus 2.9%, P = 0.042) and longer LOS (2d, IQR [1-3] versus 1d, IQR [1-2, P < 0.001). On multivariate analysis, presence of hypercortisolism was independently associated with increased likelihood of readmission within 30 d (OR 2.20, 95% CI 1.11-2.99, P = 0.012) and longer LOS (>1 d) (OR 1.79, 95% CI 1.33-2.40, P < 0.001). Compared to BNF patients, patients with pheochromocytoma had higher rates of postoperative morbidity (6.2% versus 5.2%, P < 0.001). Within the open group of 469 (11.5% of adrenalectomy patients), there were no statistically significant differences in outcomes between patients with BNF and functional adrenal masses. CONCLUSIONS: Outcomes after adrenalectomy performed for functional neoplasms differ based on surgical indication.

Perioperative Outcomes After Adrenalectomy for Secondary Adrenal Malignancy.

INTRODUCTION: The risk of adverse outcomes after adrenal metastasectomy is not well defined. Knowledge of these risks is essential to guide patient counseling. METHODS: The 2015-2020 National Surgical Quality Improvement Program datasets were combined. Patients who underwent adrenalectomy for secondary adrenal malignancy (SM) and benign nonfunctional (BNF) adrenal neoplasms were identified; BNF neoplasms were chosen as a comparison as functional neoplasms can contribute to comorbidity. Patients who had additional surgery at the time of adrenalectomy were excluded. Patient demographics, comorbidities, perioperative factors, and outcomes were compared between groups. Multivariable logistic regression analysis was performed. RESULTS: Of 3496 adrenalectomy patients, 332 had SM and 3164 had BNF neoplasms. Patients with SM were older (65 versus 54 y) and more often had chronic obstructive pulmonary disease (7.5% versus 4.4%), chronic steroid use (10.5% versus 3.8%), and bleeding disorders (4.5% versus 2.2%) than patients with BNF, respectively (P < 0.01 for all). Laparoscopic adrenalectomy was the most common operative approach for both groups (74.7% versus 88.3%). Rates of mortality, morbidity, reoperation, readmission, and nonhome discharge did not differ significantly between groups. Patients with SM had higher rates of postoperative bleeding than patients with BNF (6.3% versus 2.6%, P < 0.001). This persisted on multivariable regression analysis that adjusted for demographics, comorbidities, and operative approach (odds ratio 2.34, 95% confidence interval 1.19-4.64). CONCLUSIONS: Adrenalectomy for SM is associated with an increased risk of postoperative bleeding compared to adrenalectomy for BNF adrenal neoplasms. Patients with SM that meet criteria for adrenal metastasectomy should be counseled appropriately.

Missed Opportunities to Diagnose and Treat Tertiary Hyperparathyroidism After Transplant.

INTRODUCTION: Tertiary hyperparathyroidism (3HPT) is common after renal transplant. However, guidelines for diagnosis are not clear and few patients are treated surgically. This study aims to determine rates of diagnosis and treatment of 3HPT in renal transplant patients with hypercalcemia. MATERIALS AND METHODS: This retrospective chart review identified all renal transplant recipients at a single tertiary care institution between 2011 and 2021. Patients with post-transplant hypercalcemia (> 10.2 mg/dL) were identified. The time in months of index hypercalcemia was noted. Measurement of parathyroid hormone (PTH) levels after index hypercalcemia was determined and noted as elevated if > 64 pg/mL at least 6 mo after transplant. Documentation of symptoms of hyperparathyroidism, a diagnosis of hyperparathyroidism in the electronic medical record, and medical or surgical management of patients with classic 3HPT (elevated calcium and PTH) were determined. RESULTS: Of 383 renal transplant recipients, hypercalcemia was identified in 132 patients. The majority of hypercalcemic patients had PTH levels measured (127, 96.2%). PTH was elevated in 109 (82.6%). Among the 109 patients with classic 3HPT, 54 (49.5%) had a documented diagnosis of hyperparathyroidism in the electronic medical record (P = 0.01). Kidney stones or abnormal DEXA scan were present in 16 (14.7%) and 18 (16.5%), respectively. Most patients were managed non-surgically (101, 92.6%); calcimimetics were prescribed for 42 (38.5%, P = 0.01). Eight (7.3%) patients with classic 3HPT were referred to a surgeon (P = 0.35); all were initially prescribed calcimimetics (P = 0.001). CONCLUSIONS: 3HPT is underdiagnosed in patients with elevated calcium and PTH levels post-transplant. A significant percentage of these patients go without surgical referral and curative treatment.

From Debt to Dollars: Assessing a General Surgeon's Career Value.

INTRODUCTION: Surgical residents make decisions that may have a dramatic impact on career earnings based off conceptions regarding future income potential. This study examines the effect of debt burden, repayment plan, and practice setting on a general surgeon's career value. METHODS: Debt levels, repayment plans, and practice setting were considered to model a surgeon's career value using net present value (NPV) across 35 scenarios. The NPV was calculated using salary, education debt, yearly spending, and a discount rate of 5%. Salary data were obtained from the Medical Group Management Association, student debt information from the Association of American Medical Colleges, and tax and household spending data from U.S. government records. Assumptions included no gaps in training, no prior debt, single-person household, and career duration of 35 y. RESULTS: A general surgeon's salary adequately repays debt burdens from $100,000-$300,000 over 10-25 y, regardless of repayment plan or practice setting. Practice setting decreased career value for academic surgeons when debt burden and repayment plan were held constant: the NPV for an academic surgeon was $382,000 compared to $500,000 for a nonacademic surgeon with the same debt and repayment plan. Debt burden repaid through unsubsidized and income-based repayment plans reduced NPV for all surgeons, while subsidized plans increased NPV. The projected NPV for all scenarios ranged $2.35M-$2.87 M. CONCLUSIONS: Though the modeled scenarios do not account for prior debt burden, major expenditures, or increases in yearly household spending beyond national averages, surgery residents should be aware that general surgery remains a financially feasible career.

Not Clearing the Air: Hospital Price Transparency for a Laparoscopic Cholecystectomy.

INTRODUCTION: In 2019, Centers for Medicare and Medicaid Services (CMS) established a new requirement that all hospitals publish information on the standard costs of services provided. Increased price transparency allows patients to compare healthcare costs and make informed decisions about their care. We investigated compliance with this rule with regards to laparoscopic cholecystectomy, a commonly performed operation and one of the 70 shoppable services (SSs) included in the CMS requirement, among prominent hospitals in the United States. METHODS: The 2021-2022 US News "Best Hospitals for Gastroenterology and GI Surgery" was used to identify the top 50 hospitals for gastrointestinal surgery. Each hospital's website was assessed for the presence of a machine-readable file (MRF) as required by CMS. Each MRF was then evaluated for inclusion of all seven required elements: description of item/service, gross charge, payer-specific negotiated charge, deidentified minimum and maximum negotiated charges, discounted cash price, and billing code. The presence of a consumer-friendly display of SSs was also evaluated. The Current Procedural Terminology code 47562 (removal of gallbladder with an endoscope) was used to search for all six required elements: payer-specific negotiated charge, discounted cash price, de-identified minimum and maximum negotiated charges, campus location of the SS, and billing code. The SS display was further evaluated for provision of additional information on ancillary charges, which are recommended but not required. The MRF and SS were also evaluated for accessibility and date of last update. Hospitals were analyzed according to rank. Compliance with CMS requirements was compared between hospitals. RESULTS: Fifty one hospitals were included. Of these 51 hospitals, one (2%) provided all the required information for both MRF and SS, 44 (86%) did not provide all necessary components of both the MRF and SS, six (12%) had all necessary elements of an MRF only, and two (4%) had all necessary elements of the SS only. The MRF was accessible in 80% (41) of studied hospitals and 76% (39) provided a gross charge but just 35% (18) of hospitals included the discounted cash price. The SS specified location for all hospitals, indicated a billing code in 96% (49), and provided a payer-specific charge in 96% (48), but less often provided de-identified minimum (30; 59%) and maximum (30; 59%) charges. Thirty nine (76%) hospitals reported that the listed price included an ancillary charge. There was no significant difference between hospitals in having all required elements of both the MRF and SS or the MRF only or SS only. CONCLUSIONS: Hospitals are providing healthcare consumers with standard charge information, although with significant variation in what is disclosed. There is no association between hospital reputation and provision of standard charge information.

Phase 1 trial of adavosertib (AZD1775) in combination with concurrent radiation and cisplatin for intermediate-risk and high-risk head and neck squamous cell carcinoma.

BACKGROUND: Adavosertib (AZD1775) is an inhibitor of the Wee1 kinase. The authors conducted a phase 1b trial to evaluate the safety of adavosertib in combination with definitive chemoradiotherapy for patients with newly diagnosed, intermediate-risk/high-risk, locally advanced head and neck squamous cell carcinoma (HNSCC). METHODS: Twelve patients with intermediate-risk/high-risk HNSCC were enrolled, including those with p16-negative tumors of the oropharynx, p16-positive tumors of the oropharynx with ≥10 tobacco pack-years, and tumors of the larynx/hypopharynx regardless of p16 status. All patients were treated with an 8-week course of concurrent intensity-modulated radiotherapy at 70 grays (Gy) (2 Gy daily in weeks 1-7), cisplatin 30 mg/m2 weekly (in weeks 1-7), and adavosertib (twice daily on Monday, Tuesday, and Wednesday of weeks 1, 2, 4, 5, 7, and 8). The primary objective was to determine the maximum tolerated dose and the recommended phase 2 dose of adavosertib given concurrently with radiation and cisplatin. Secondary objectives were to determine the 12-week objective response rate and progression-free and overall survival. RESULTS: Three patients (25%) experienced a dose-limiting toxicity, including febrile neutropenia (n = 2) and grade 4 thromboembolism (n = 1). Two dose-limiting toxicities occurred with adavosertib at 150 mg. The median follow-up was 14.7 months. The 12-week posttreatment objective response rate determined by positron emission tomography/computed tomography was 100%. The 1-year progression-free and overall survival rates were both 90%. The maximum tolerated dose of adavosertib was 100 mg. CONCLUSIONS: Adavosertib 100 mg (twice daily on Monday, Tuesday, and Wednesday of weeks 1, 2, 4, 5, 7, and 8), in combination with 70 Gy of intensity-modulated radiotherapy and cisplatin 30 mg/m2 , is the recommended phase 2 dose for patients with HNSCC.

A Multidisciplinary Breast Cancer Brain Metastases Clinic: The University of North Carolina Experience.

BACKGROUND: Breast cancer brain metastasis (BCBM) confers a poor prognosis and is unusual in requiring multidisciplinary care in the metastatic setting. The University of North Carolina at Chapel Hill (UNC-CH) has created a BCBM clinic to provide medical and radiation oncology, neurosurgical, and supportive services to this complex patient population. We describe organization and design of the clinic as well as characteristics, treatments, and outcomes of the patients seen in its first 3 years. METHODS: Clinical and demographic data were collected from patients in a prospectively maintained database. Descriptive statistics are reported as percentages and means. The Kaplan-Meier method was used to estimate time-to-event outcomes. RESULTS: Sixty-five patients were seen between January 2012 and January 2015. At the time of presentation to the BCBM clinic, most patients (74%) had multiple (≥2) brain metastases and had received prior systemic (77%) and whole-brain radiation therapy and/or central nervous system stereotactic radiosurgery (65%) in the metastatic setting. Seventy-eight percent returned for a follow-up visit; 32% were enrolled in a clinical trial. Median time from diagnosis of brain metastasis to death was 2.11 years (95% confidence interval [CI] 1.31-2.47) for all patients, 1.15 years (95% CI 0.4-2.43) for triple-negative breast cancer, 1.31 years (95% CI 0.51-2.52) for hormone receptor-positive/HER2- breast cancer, and 3.03 years (95% CI lower limit 1.94, upper limit not estimable) for HER2+ breast cancer (p = .0037). CONCLUSION: Patients with BCBM have unique and complex needs that require input from several oncologic disciplines. The development of the UNC-CH multidisciplinary BCBM clinic is a model that can be adapted at other centers to provide coordinated care for patients with a challenging and complex disease. IMPLICATIONS FOR PRACTICE: Patients with breast cancer brain metastases often require unique multidisciplinary care to meet the numerous and uncommon challenges associated with their conditions. Here, the development and characteristics of a clinic designed specifically to provide for the multidisciplinary needs of patients with breast cancer brain metastases are described. This clinic may serve as a model for other institutions interested in creating specialty clinics with similar objectives.

Time is money: The return on investment of research in surgical training: The ROI of research in surgical training.

INTRODUCTION: Future income potential can impact surgical trainees' career choices, particularly when deciding to subspecialize, which often requires additional training and research time. This study quantifies the effects of added time on career value for eight surgical subspecialties. METHODS: The Net present value(NPV) was calculated for eight subspecialties and general surgery over a 35-year career, factoring in salary, educational debt, tax, inflation, and practice setting. NPV for each was compared over a number of research years (0, 1, 2) using data from the MGMA, AAMC, and US government records. RESULTS: After a 35-year career, six subspecialties in private practice increased career NPV(>$14,000) with 0 research years. One additional research year yielded negative career values for transplant, trauma, and vascular; with two, only cardiovascular and pediatric retained a positive NPV. In academia, 1-2 research years resulted in negative NPV for all but cardiovascular and thoracic surgery. CONCLUSIONS: The financial return of additional training years is highly variable.

Parental leave experiences for the non-childbearing general surgery resident parent: A qualitative analysis.

BACKGROUND: Stigma surrounds parental leave during general surgery residency, yet 25% to 29% of general surgery residents have children. Parental leave experiences of non-childbearing general surgery resident parents have not been described. This study aimed to describe the non-childbearing population's parental leave experiences. METHODS: Using a purposive sampling strategy, semi-structured interviews (n = 20) were conducted via Zoom (August 2021-March 2022) with current general surgery residents or fellows who had at least 1 child during residency as the non-childbearing parent. Interviews explored participants' experiences with parental leave policies, timing, structure, motivations/influences for taking leave, career/training impacts, and reflections on their experiences. Transcripts were analyzed using thematic content analysis. Participant demographics were analyzed using univariate analysis. RESULTS: Of the 20 participants, there were 31 unique parental leave experiences. The following 6 themes were identified from interviews: program/professional policies, cultural climate, support (institutional and social), parental leave experiences, impact, and recommendations. Participants cited needing to rely on informal support (eg, the assistance of other residents) to arrange leave and feeling compelled not to take the full time allowed in order to not burden co-residents or because others took less time. Overall, participants felt dissatisfied with their parental leave experiences. CONCLUSION: Non-childbearing general surgery resident parents underuse parental leave due to perceived or actual lack of access to leave and stigma. This results in dissatisfaction with their parental leave experiences and has the potential to lead to negative professional and personal outcomes. There is a critical need for improved support through cultural change and policy revision, implementation, and adherence.

To report hounsfeld units or not: There is no question.

INTRODUCTION: Most adrenal incidentalomas are not appropriately evaluated. Reporting the mass in the radiology report summary and providing recommendations in the report can positively impact evaluation. This study evaluated the effect of reporting Hounsfield units(HU) on adrenal incidentaloma follow-up. METHODS: Patients with adrenal incidentalomas identified on noncontrast CT scan from 2015 to 2020 â€‹at a tertiary care institution were studied. Chart review was conducted. Patient and imaging characteristics were compared between patients who did and did not have HU reported. Outcomes of interest were 1)outpatient referral, 2)biochemical evaluation, and 3)dedicated imaging if appropriate. Multivariate analysis determined the impact of HU, reporting in the summary and provision of recommendations on the outcomes. RESULTS: 363 patients were studied, 36(9.9 â€‹%) had HU reported. When HU were used in addition to recommendations and reporting in the summary, the likelihood of outpatient referral increased from 10.1 to 32.6-fold (95%CI 7.7-138.1, p â€‹< â€‹0.001). Similarly, the likelihood of biochemical workup increased from 2.5 to 7.8-fold (95%CI 2.5-24.1, p â€‹< â€‹0.001). CONCLUSION: Recording adrenal incidentaloma HU on non-contrast CT scans was associated with increased rates of outpatient referral and biochemical workup.

A thorough evaluation for primary hyperparathyroidism: More than a stone's throw away.

BACKGROUND: Primary hyperparathyroidism (PHPT) is a treatable cause of nephrolithiasis. However, PHPT is not consistently evaluated in nephrolithiasis patients. Symptoms of parathyroid disease were explored in relation to evaluation of PHPT in nephrolithiasis patients. METHODS: Patients with nephrolithiasis on imaging between 2017 and 2021 were identified. Measurement of serum calcium levels after nephrolithiasis diagnosis was determined. Patients with hypercalcemia (≥ 10.2 â€‹mg/dL) were identified. Characteristics associated with parathyroid hormone (PTH) evaluation and specialist referral were assessed. RESULTS: Of 2264 nephrolithiasis patients with calcium levels measured, 383 (17.1 â€‹%) had hypercalcemia. Of those, 107 (27.9 â€‹%) had PTH levels drawn. PTH was more often assessed in patients with higher median calcium levels, recurrent nephrolithiasis, depression, and osteopenia/osteoporosis. PTH was elevated (>64 â€‹pg/mL) or non-suppressed (40-64 â€‹pg/mL) in 68 (63.6 â€‹%) patients. Of those, 31 (45.6 â€‹%) were referred to a parathyroid specialist. Referred patients had higher PTH and calcium levels than those without referral, and higher rates of osteopenia/osteoporosis. CONCLUSIONS: PTH evaluation in hypercalcemic nephrolithiasis patients was low. The majority of patients evaluated had elevated or non-suppressed PTH levels, but only a fraction were referred to a specialist.

Safety of thyroidectomy in hospitalized patients: A descriptive analysis of the NSQIP thyroidectomy-targeted data.

BACKGROUND: Some patients undergo thyroidectomy while hospitalized for a related or independent indication. Outcomes have not been described in this group. METHODS: The 2016-2018 thyroidectomy-targeted NSQIP datasets were queried for patients admitted for ≥1 day preoperatively. 1:1 propensity score matching was employed to compare the outcomes of admitted patients to outpatients, including surgical and thyroidectomy-specific outcomes. Multivariable logistic regression determined factors associated with poor outcomes. RESULTS: Of 18,078 patients, 312 were admitted at least 1 day prior to surgery. Inpatients had higher ASA classifications and rates of several comorbidities compared to the general population. After propensity score matching, inpatients had higher rates of overall complications, unplanned reoperation, and bleeding. They also experienced higher rates of thyroidectomy-specific complications such as hypocalcemia and neck hematoma. By multivariable regression, admission prior to surgery was associated with development of any complications. CONCLUSION: Thyroidectomy in hospitalized patients carries an increased risk of complications. Patients requiring thyroidectomy while already hospitalized should be counseled accordingly.

Disparities in Access to High-Volume Surgeons and Specialized Care.

The significant volume-outcome relationship has triggered interest in improving quality of care by directing patients to high-volume centers and surgeons. However, significant disparities exist for different racial/ethnic, geographic, and socioeconomic groups for thyroid, parathyroid, adrenal, and pancreatic neuroendocrine surgical diseases disease.

Does race impact outcomes after parathyroidectomy for secondary and tertiary hyperparathyroidism?

BACKGROUND: Racial disparities in care exist for diseases with heterogeneous treatment guidelines. The impact of these disparities on outcomes after parathyroidectomy for secondary(2HPT) and tertiary hyperparathyroidism(3HPT) was explored. METHODS: The 2015-2019 NSQIP datasets were used. Patients who underwent parathyroidectomy for 2HPT and 3HPT were identified and analyzed separately. Patients were stratified by race (white vs. non-white); demographics, comorbidities, and outcomes were compared. Studied outcomes included 30-day morbidity, mortality, unplanned reoperation, readmission, and postoperative length of stay(LOS). RESULTS: There were 1,150 patients with 2HPT and 262 with 3HPT. For 2HPT, 65.5% were non-white; morbidity, reoperation, and prolonged LOS(>3days) occurred disproportionately more often in non-white patients. Non-white race was independently associated with morbidity; higher ASA class and alkaline phosphatase levels were associated with prolonged LOS. For 3HPT, 53.1% were non-white; a prolonged LOS(>1day) occurred disproportionately more often in non-white patients. Higher alkaline phosphatase levels were independently associated with prolonged LOS. CONCLUSION: Race and markers of advanced disease negatively impact outcomes after parathyroidectomy for 2HPT and 3HPT. Attention to racial disparities and earlier referral may positively impact outcomes.

Older age impacts outcomes after adrenalectomy.

BACKGROUND: Adrenalectomy is well tolerated with low complication rates. It is unclear if these excellent outcomes are consistent across all age groups. METHODS: The 2015-2020 American College of Surgeons National Surgical Quality Improvement Program datasets were used. Patients who underwent adrenalectomy were identified and grouped based on age: ≤60, 61 to 70, 71 to 80, and >80 years. Patient characteristics, surgical indications, operative characteristics, and postoperative outcomes were compared between age groups. Primary outcome measures were mortality, morbidity, postoperative length of stay, non-home discharge, and unplanned readmission. Multivariable logistic regression analysis was performed. RESULTS: Adrenalectomy was performed on 6,114 patients. Younger patients more frequently had surgery for non-functional benign neoplasms compared with older (55.7% vs 52.8% vs 45.9% vs 45.3%, for patients ≤60, 61 to 70, 71 to 80, and >80 years, respectively, P < .001), and less frequently had surgery for malignancy (8.8% vs 14.4% vs 22.5% vs 24.5%, P < .001). The median length of stay for patients ≤60 was 1 day compared with 2 days for patients 61-70, 71-80, and >80 (P < .001). The overall mortality rate was <1% and did not differ based on age (P = .18). Morbidity occurred less frequently in the younger age groups (7.3% vs 8.9% vs 11.2% vs 16.0%, P < .001) compared with older. Similar trends were seen for non-home discharge (1.4% vs 2.5% vs 4.8% vs 17.0%, P < .001). On multivariable analysis, patients aged >80 had a 2-fold increased likelihood of morbidity and a 9-fold increased likelihood of non-home discharge compared to patients aged ≤60. CONCLUSION: Older age is associated with morbidity and non-home discharge after adrenalectomy. Knowledge of these risks is critical when counseling an aging surgical population.

Assessing the impact of radiation-induced changes in soft tissue density ∕ thickness on the study of radiation-induced perfusion changes in the lung and heart.

PURPOSE: Abnormalities in single photon emission computed tomography (SPECT) perfusion within the lung and heart are often detected following radiation for tumors in∕around the thorax (e.g., lung cancer or left-sided breast cancer). The presence of SPECT perfusion defects is determined by comparing pre- and post-RT SPECT images. However, RT may increase the density of the soft tissue surrounding the lung∕heart (e.g., chest wall∕breast) that could possibly lead to an "apparent" SPECT perfusion defect due to increased attenuation of emitted photons. Further, increases in tissue effective depth will also increase SPECT photon attenuation and may lead to "apparent" SPECT perfusion defects. The authors herein quantitatively assess the degree of density changes and effective depth in soft tissues following radiation in a series of patients on a prospective clinical study. METHODS: Patients receiving thoracic RT were enrolled on a prospective clinical study including pre- and post-RT thoracic computed tomography (CT) scans. Using image registration, changes in tissue density and effective depth within the soft tissues were quantified (as absolute change in average CT Hounsfield units, HU, or tissue thickness, cm). Changes in HU and tissue effective depth were considered as a continuous variable. The potential impact of these tissue changes on SPECT images was estimated using simulation data from a female SPECT thorax phantom with varying tissue densities. RESULTS: Pre- and serial post-RT CT images were quantitatively studied in 23 patients (4 breast cancer, 19 lung cancer). Data were generated from soft tissue regions receiving doses of 20-50 Gy. The average increase in density of the chest was 5 HU (range 46 to -69). The average change in breast density was a decrease of -1 HU (range 13 to -13). There was no apparent dose response in neither the dichotomous nor the continuous analysis. Seventy seven soft tissue contours were created for 19 lung cancer patients. The average change in tissue effective depth was +0.2 cm (range -1.9 to 2.2 cm). The changes in HU represent a <2% average change in tissue density. Based on simulation, the small degree of density and tissue effective depth change is unlikely to yield meaningful changes in either SPECT lung or heart perfusion. CONCLUSIONS: RT doses of 20-50 Gy can cause up to a 46 HU increase in soft tissue density 6 months post-RT. Post-RT soft tissue effective depth may increase by 2.0 cm. These modest increases in soft tissue density and effective depth are unlikely to be responsible for the perfusion changes seen on post-RT SPECT lung or heart scans. Further, there was no clear dose response of the soft tissue density changes. Ultimately, the authors findings suggest that prior perfusion reports do reflect changes in the physiology of the lungs and heart.

Current U.S. Pre-Operative Bowel Preparation Trends: A 2018 Survey of the American Society of Colon and Rectal Surgeons Members.

Background: The effect of an oral antibiotic preparation prior to colorectal surgery was first examined and exalted in the 1973 paper by Nichols et al. Since this commencement, enthusiasm for the oral antibiotic regimen has waxed and waned reflecting the literature focused on this topic over the past 40 years. Polling colorectal surgeons of define current practices has been performed at intervals throughout the years and has demonstrated a trend to decline in the practice. The most recent publication surveying U.S. practices was in 2010, which reported a minority, 36%, use of oral antibiotics prior to elective colorectal surgery; a marked downtrend from the 88% use described in 1990. Since this last survey, the colorectal surgery community has performed considerable research examining the benefit of oral antibiotic and mechanical bowel preparation. This manuscript evaluates the current use of oral antibiotics in colorectal surgery in the U.S. and how practice trends have developed in response to current recommendations in the literature. Methods: An electronic survey was created and distributed to U.S. colorectal surgeons to evaluate current opinions and practice trends. A total of 359 American Society of Colon and Rectal Surgeons members responded. A review of the recent literature pertaining to pre-operative bowel practices and outcomes was performed to compare with current practices. Results: A significant majority (83.2%) of respondents use pre-operative oral antibiotics routinely, and 98.6% routinely use mechanical bowel preparation. The use of a combination of parenteral antibiotics, oral antibiotics, and mechanical bowel preparation is reported by 79.3%. The most commonly employed oral antibiotic regimen is neomycin and metronidazole. The most common mechanical bowel preparation is polyethylene glycol (PEG). The most common parenteral antibiotics are cefazolin and metronidazole. There was no statistically significant difference in this practice by geographic region, Board-certified status, or practice setting. Conclusion: The majority of colorectal surgeons employ a combination of oral antibiotics, mechanical bowel preparation, and parenteral antibiotics prior to colorectal surgery. This is consistent across geographic regions, despite Board certification status or practice setting, and is reflective of the recommendations based on recent literature.

Reentry of elementary aged children following reunification from foster care.

A recognized goal of family reunification programs is preventing the reentry of children into foster care. Using data from the National Survey of Child and Adolescent Well-Being, this study examined reentry for 273 children between the ages of 5 and 12 years. In multivariate models, reentry into foster care was associated with higher Child Behavior Checklist (CBCL) scores and higher numbers of children in the household when the child is living at home. Although these are not the only risk factors that should be considered in deciding whether to reunify a child, these characteristics appear to be high valence problems for families and their children who are reunified. Future research on reentry and on placement disruptions from foster care should routinely include information about the number of children in the family and behavior problems when endeavoring to explain caseload dynamics.

Outcomes for youth receiving intensive in-home therapy or residential care: a comparison using propensity scores.

This study compares outcomes for behaviorally troubled children receiving intensive in-home therapy (IIHT) and those receiving residential care (RC). Propensity score matching is used to identify matched pairs of youth (n = 786) with equivalent propensity for IIHT. The majority of pretreatment differences between the IIHT and RC groups are eliminated following matching. Logistic regression is then conducted on outcome differences at 1 year postdischarge. Results show that IIHT recipients had a greater tendency (.615) toward living with family, making progress in school, not experiencing trouble with the law, and placement stability compared with RC youth (.558; p < .10). This suggests that IIHT is at least as effective for achieving positive outcomes. Given IIHT's reduced restrictiveness and cost, intensive in-home services should be the preferred treatment over RC in most cases.
