RESUMEN
BACKGROUND: Guidelines recommend extended venous thromboembolism (VTE) prophylaxis for high-risk populations undergoing major abdominal cancer operations. Few studies have evaluated extended VTE prophylaxis in the Medicare population who are at higher risk due to age. METHODS: We performed a retrospective study using a 20% random sample of Medicare claims, 2012-2017. Patients ≥65 years with an abdominal cancer undergoing resection were included. Primary outcome was the proportion of patients receiving new extended VTE prophylaxis prescriptions at discharge. Secondary outcomes included postdischarge VTE and hemorrhagic events. RESULTS: The study included 72 983 patients with a mean age of 75. Overall, 8.9% of patients received extended VTE prophylaxis. This proportion increased (7.2% in 2012, 10.6% in 2017; p < 0.001). Incidence of postdischarge hemorrhagic events was 1.0% in patients receiving extended VTE prophylaxis and 0.8% in those who did not. The incidence of postdischarge VTE events was 5.2% in patients receiving extended VTE prophylaxis and 2.4% in those who did not. CONCLUSION: Adherence to guideline-recommended extended VTE prophylaxis in high-risk patients undergoing major abdominal cancer operations is low. The higher rate of VTE in the prophylaxis group may suggest we captured some therapeutic anticoagulation, which would mean the actual rate of thromboprophylaxis is lower than reported herein.

INTRODUCTION: Nonoperative management (NOM) of acute appendicitis in the pediatric population is highly debated with uncertain cost-effectiveness. We performed a decision tree cost-effectiveness analysis of NOM versus early laparoscopic appendectomy (LA) for acute appendicitis in children. METHODS: We created a decision tree model for a simulated cohort of 49,000 patients, the number of uncomplicated appendectomies performed annually, comparing NOM and LA. We included postoperative complications, recurrent appendicitis, and antibiotic-related complications. We used the payer perspective with a 1-year time horizon. Model uncertainty was analyzed using a probabilistic sensitivity analysis. Event probabilities, health-state utilities, and costs were obtained from literature review, Healthcare Cost and Utilization Project, and Medicare fee schedules. RESULTS: In the base-case analysis, NOM costs $6530/patient and LA costs $9278/patient on average at 1 y. Quality-adjusted life year (QALY) differences minimally favored NOM compared to LA with 0.997 versus 0.996 QALYs/patient. The incremental cost-effectiveness ratio for NOM over LA was $4,791,149.52/QALY. NOM was dominant in 97.4% of simulations, outperforming in cost and QALYs. A probabilistic sensitivity analysis showed NOM was 99.6% likely to be cost-effective at a willingness-to-pay threshold of $100,000/QALY. CONCLUSIONS: Our model demonstrates that NOM is a dominant strategy to LA over a 1-year horizon. We use recent trial data demonstrating higher rates of early and late NOM failures. However, we also incorporate a shorter length of index hospitalizations with NOM, reflecting a contemporary approach to NOM and ultimately driving cost-effectiveness. Long-term follow-up data are needed in this population to assess the cost-effectiveness of NOM over longer time horizons, where healthcare utilization and recurrence rates may be higher.

BACKGROUND: Children, adolescents, and young adults (CAYA) (age ≤39 years) with GIST have high rates of LNM, but their clinical relevance is undefined. This study analyzed the impact of LNM on overall survival (OS) for CAYA with GIST. METHODS: The National Cancer Database was queried for patients with resected GIST and pathologic nodal staging data from 2004-2019. Factors associated with LNM were identified. Survival was assessed stratified by presence of LNM. RESULTS: Of 4420 patients with GIST, 238 were CAYA (5.4%). When compared to older adults, CAYA more often had small intestine primaries (51.8% vs. 36.6%, p < 0.0001), T4 tumors (30.7% vs. 24.5%, p = 0.0275) and pN1 disease (11.3% vs. 4.7%, p < 0.0001). Within a multivariable Cox proportional hazards regression model adjusting for age, comorbid disease, mitotic rate, tumor size, and primary site, LNM were associated with increased hazard of death for older adults (hazard ratio [HR]: 1.83; confidence interval [CI]: 1.35-2.42; p < 0.0001), but not CAYA (HR: 3.38; CI: 0.50-14.08; p = 0.13). For CAYA, only high mitotic rate predicted mortality (HR: 4.68; CI: 1.41-18.37: p = 0.02). CONCLUSIONS: LNM are more commonly identified among CAYA with resected GIST who undergo lymph node evaluations, but do not appear to impact OS as observed in older adults. High mitotic rate remains a predictor of poor outcomes for CAYA with GIST.

BACKGROUND: There are multiple different systems that define a rural area in health services research, but few studies compare their ability to measure access to health resources. Our objective was to compare various definitions of rurality to determine which system best measures local surgeon supply. MATERIALS AND METHODS: In this retrospective observational study, we used the 2019 Area Health Resource File to obtain the 2017 county-level supply of general surgeons, surgical subspecialists, and total physicians for all counties in the United States. Physicians per 100,000 population were calculated for each physician measure and were the primary outcomes. The rural-urban measurements included were the Office of Management and Budget 2017 definition, Urban Influence Codes (UIC), Rural-Urban Commuting Codes (RUCCs), and Census urban population within the county. We also developed and tested a measure combining the RUCCs and Census urban population. Linear regression was used to compare performance of these definitions for each outcome using adjusted R2 values. RESULTS: In 3138 counties included in the study, dichotomous measures of rural-urban using the UIC/RUCC had the lowest adjusted R2 values across all outcomes. Quartiles using the Census urban population and the RUCC/Census urban population combined measure had the highest adjusted R2 values for all outcomes. CONCLUSIONS: The Census urban population had the best performance in measuring geographic access to surgical care. This study can inform surgical health services researchers who want to include measures of rurality in their analysis.

INTRODUCTION: There are multiple measures of area socioeconomic status (SES) and there is little evidence on the comparative performance of these measures. We hypothesized adding area SES measures improves model ability to predict guideline concordant care and overall survival compared to models with standard clinical and demographic data alone. MATERIALS AND METHODS: We included patients with colorectal cancer from 2006 to 2015 from the North Carolina Cancer Registry merged with insurance claims data. The primary area SES study variables were the Social Deprivation Index, Distressed Communities Index, Area Deprivation Index, and Social Vulnerability Index. We used multivariable logistic modeling and Cox proportional hazards modeling to assess the adjusted association of each indicator, with guideline concordant care and overall survival, respectively. Model performance of the SES measures was compared to a base model using likelihood ratio testing and area under the curve (AUC) assessments to compare SES indicator models with each other. RESULTS: We found that the Area Deprivation Index, Social Vulnerability Index and Social Deprivation Index, but not Distressed Communities Index, were significantly associated with receiving guideline concordant care and significantly improved model fit over the base model on likelihood ratio testing. All models had similar AUCs. With respect to overall survival, we found that all indices were independently and significantly associated with survival and had significantly improved model fit over the base model on likelihood ratio testing. AUC analysis again showed all area SES measures had comparable performance for overall survival at 5 y. CONCLUSIONS: This analysis demonstrates the importance of including these measures in risk adjustment models. However, of the commonly available measures, no one measure stood out as superior to others.

PURPOSE: Improved outcomes in lung cancer treatment are seen in high-volume academic centers, making it important to understand barriers to accessing care at such institutions. Few qualitative studies examine the barriers and facilitators to early-stage lung cancer care at US academic institutions. METHODS: Adult patients with suspected or diagnosed early-stage non-small cell lung cancer presenting to a multidisciplinary lung cancer clinic at a US academic institution over a 6-month period beginning in 2019 were purposively sampled for semi-structured interviews. Semi-structured interviews were conducted and a qualitative content analysis was performed using the framework method. Themes relating to barriers and facilitators to lung cancer care were identified through iterative team-based coding. RESULTS: The 26 participants had a mean age of 62 years (SD: 8.4 years) and were majority female (62%), white (77%), and urban (85%). We identified 6 major themes: trust with providers and health systems are valued by patients; financial toxicity negatively influenced the diagnostic and treatment experience; social constraints magnified other barriers; patient self-advocacy as a facilitator of care access; provider advocacy could overcome other barriers; care coordination and good communication were important to patients. CONCLUSIONS: We have identified several barriers and facilitators to lung cancer care at an academic center in the US. These factors need to be addressed to improve quality of care among lung cancer patients. Further work will examine our findings in a community setting to understand if our findings are generalizable to patients who do not access a tertiary cancer care center.

BACKGROUND Our objectives were to evaluate geographic access to lung cancer treatment modalities in North Carolina and to characterize how practice patterns are changing over time. We hypothesized that rural patients would be less likely to undergo treatment compared to urban patients, with widening disparities over time.METHODS We identified patients with Stage I non-small cell lung cancer (NSCLC) from 2006 to 2015 using the North Carolina Central Cancer Registry linked with Medicaid, Medicare, and private insurance claims. The primary outcome was first-course treatment: surgery, radiation, or no treatment. Calendar years were split into earlier (2006-2010) and later (2011-2015) periods. We estimated the adjusted odds ratio (OR) of rural/urban status and time period with 1) surgery and 2) any treatment (surgery or radiation) using multivariable logistic regression.RESULTS Among 5504 patients, 3206 (58%) underwent surgery as initial therapy, 1309 (24%) received radiation as initial therapy, and 989 (18%) had no therapy. There were no rural-urban disparities in treatment patterns. For rural and urban patients, the odds of surgery decreased over time and the odds of radiation increased. We also found that only 48% of those receiving no treatment ever reached a surgeon or radiation oncologist.LIMITATIONS This was an insured, single-state population. Treatment preferences are unknown.CONCLUSIONS Among all treated patients, whether urban or rural, there was increasing use of radiation and decreasing use of surgery over time. Many patients without treatment never had a consultation with a surgeon/radiation oncologist, and this is an actionable target for improving treatment access for early-stage NSCLC.

PURPOSE: SEER data are widely used to study rural-urban disparities in cancer. However, no studies have directly assessed how well the rural areas covered by SEER represent the broader rural United States. METHODS: Public data sources were used to calculate county level measures of sociodemographics, health behaviors, health access and all cause cancer incidence. Driving time from each census tract to nearest Commission on Cancer certified facility was calculated and analyzed in rural SEER and non-SEER areas. RESULTS: Rural SEER and non-SEER counties were similar with respect to the distribution of age, race, sex, poverty, health behaviors, provider density, and cancer screening. Overall cancer incidence was similar in rural SEER vs non-SEER counties. However, incidence for White, Hispanic, and Asian patients was higher in rural SEER vs non-SEER counties. Unadjusted median travel time was 53 min (IQR 34-82) in rural SEER tracts and 54 min (IQR 35-82) in rural non-SEER census tracts. Linear modeling showed shorter travel times across all levels of rurality in SEER vs non-SEER census tracts when controlling for region (Large Rural: 13.4 min shorter in SEER areas 95% CI 9.1;17.6; Small Rural: 16.3 min shorter 95% CI 9.1;23.6; Isolated Rural: 15.7 min shorter 95% CI 9.9;21.6). CONCLUSIONS: The rural population covered by SEER data is comparable to the rural population in non-SEER areas. However, patients in rural SEER regions have shorter travel times to care than rural patients in non-SEER regions. This needs to be considered when using SEER-Medicare to study access to cancer care.

BACKGROUND: The utility of sentinel lymph node biopsy (SLNB) for non-ulcerated T1b melanoma is debated and associated costs are poorly characterized. Prior work using institutional registries may overestimate the incidence of nodal positivity in this population. OBJECTIVE: The aim of this study was to estimate the use of SLNB, positivity prevalence, and procedural costs in patients with non-ulcerated T1b melanoma using a population-based registry. METHODS: We identified patients with clinically node-negative, non-ulcerated melanoma 0.8-1.0 mm thick (T1b according to the 8th edition standard of the American Joint Committee on Cancer) in the Surveillance, Epidemiology, and End Results database from 2010 to 2016. The prevalence of SLNB procedures and positive sentinel nodes were calculated. Factors associated with SLNB and sentinel node positivity were assessed using logistic regression. Medicare reimbursement costs and patient out-of-pocket expenses for SLNB and wide local excision (WLE) versus WLE alone were estimated. RESULTS: Among 7245 included patients, 3835(53%) underwent SLNB, 156 (4.1%, 95% confidence interval 3.5-4.7) of whom had a positive SLNB. Younger age, >1 mitosis per mm2, female sex, and truncal tumor location were associated with higher odds of positivity. The estimated SLNB cost to identify one patient with stage III disease was $71,700 (range $54,648-$83,172). Out-of-pocket expenses for a Medicare patient were estimated to be $652 for a WLE and SLNB and $79 for a WLE alone. CONCLUSIONS: In this population-based study, only 4% of selected non-ulcerated T1b patients had a positive SLNB, which is lower than prior reports. At the population level, SLNB is associated with high costs per prognostic information gained.

BACKGROUND: In the era of lung cancer screening with low-dose computed tomography, there is concern that high false-positive rates may lead to an increase in nontherapeutic lung resection. The aim of this study is to determine the current rate of major pulmonary resection for ultimately benign pathology. MATERIALS AND METHODS: A single-institution, retrospective analysis of all patients > 18 y who underwent major pulmonary resection between 2013 and 2018 for suspected malignancy and had benign final pathology was performed. RESULTS: Of 394 major pulmonary resections performed for known or presumed malignancy, 10 (2.5%) were benign. Of these 10, the mean age was 61.1 y (SD 14.6). Most were current or former smokers (60%). Ninety percent underwent a fluorodeoxyglucose positron emission tomography scan. Median nodule size was 27 mm (IQR 21-35) and most were in the right middle lobe (50%). Preoperative biopsy was performed in four (40%) but were nondiagnostic. Video-assisted thoracoscopic lobectomy (70%) was the most common surgical approach. Final pathology revealed three (30%) infectious, three (30%) inflammatory, two (20%) fibrotic, and two (20%) benign neoplastic nodules. Two (20%) patients had perioperative complications, both of which were prolonged air leaks, one (10%) patient was readmitted within 30 d, and there was no mortality. CONCLUSIONS: A small percentage of patients (2.5% in our series) may undergo major pulmonary resection for unexpectedly benign pathology. Knowledge of this rate is useful to inform shared decision-making models between surgeons and patients and evaluation of thoracic surgery program performance.

BACKGROUND AND OBJECTIVES: Synovial, clear cell, angiosarcoma, rhabdomyosarcoma, and epithelioid (SCARE) soft tissue sarcoma are at risk for nodal involvement, although the nodal positivity rates and impact on prognostication in clinically node negative patients are not well described. METHODS: Patients with extremity SCARE sarcoma without clinical nodal involvement undergoing surgical resection in the National Cancer Database (2004-2017) were included. Logistic regression was used to evaluate the likelihood of nodal surgery and nodal positivity. Kaplan-Meier method and Cox regression were used to assess associations of nodal status to overall survival. RESULTS: We included 4158 patients, and 669 patients (16%) underwent regional lymph node surgery (RLNS). On multivariable logistic analysis, patients with epithelioid (odds ratio [OR]: 3.77; p < .001) and clear cell (OR: 6.38; p < .001) were most likely to undergo RLNS. Forty-five patients (7%) had positive nodes. Clear cell sarcoma (14%) and angiosarcoma (13%) had the highest rates of nodal positivity. Patients with positive nodes had reduced 5-year overall survival, and the stratification was largest in clear cell and angiosarcoma. CONCLUSION: Discordance exists between selection for pathologic nodal evaluation and factors associated with nodal positivity. Clinically node negative patients with clear cell and angiosarcoma should be considered for pathologic nodal evaluation.

BACKGROUND: Our objective was to evaluate differences in baseline characteristics, complications, and mortality among patients receiving a gastrostomy tube (GT) by surgical or non-surgical services. METHODS: We performed a retrospective analysis of adult patients who underwent GT placement from 2014 to 2017 at a single institution. Using bivariate and multivariable analyses, we compared baseline characteristics, complications, and overall 30-day mortality of patients undergoing GT placement with surgical or non-surgical services. RESULTS: Of the 1339 adults who underwent GT placement, surgical and non-surgical services performed 45% (n = 609) and 55% (n = 730) procedures, respectively. Gastrostomy tube-related complications were similar (29.6% surgical vs 28.8% non-surgical, P = .76). Thirty-day mortality was higher among non-surgical services (23.7% vs 16.5%, P = .004). On multivariable analysis, this was not significant (OR 1.21, 95% CI 0.83; 1.77). CONCLUSION: Surgical and non-surgical service placement of GTs had equivalent GT-related mortality and complication rates.

PURPOSE: We evaluated temporal trends in rural-urban disparities of the surgeon supply among surgeons commonly treating patients with cancer. METHODS: We performed a retrospective observational study of county-level workforce changes from 2004 to 2017 using the Area Health Resource File. We calculated physician density (providers/100,000 population) for each specialty by rural and urban counties using the 2003 Rural-Urban Commuting Codes (RUCC), and evaluated percent changes in the rural-urban disparity in physician density. Secondary analyses evaluated these changes by Census region. Additionally, Gini indices were calculated by year and RUCC to evaluate the workforce inequality within rural areas. FINDINGS: Total surgical specialist density declined in rural areas from 16 to 14 per 100,000 population, and declined slightly from 33 to 31 per 100,000 population in urban areas, for a rural-urban disparity increase of 8% (95% CI 5%,10%). Among specific specialties, the percentage increase in the rural-urban workforce supply disparity was largest for colorectal surgeons and general surgeons at 66% (95% CI 51%,80%) and 72% (95% CI 58%,86%), respectively, although absolute changes were small. Regional heterogeneity of the workforce was higher for rural areas than urban areas. CONCLUSIONS: Changes in the rural-urban physician workforce disparities over time are dependent upon specialty, region, and local community factors. This highlights how surgical workforce policy should be oriented to the local area circumstances.

BACKGROUND: Breast angiosarcoma is a rare malignancy classically associated with hematogenous metastases. We sought to determine the prevalence of pathologic nodal involvement in patients with nonmetastatic, resected breast angiosarcoma and its association with overall survival. STUDY DESIGN: The National Cancer Database was used to identify patients with nonmetastatic angiosarcoma of the breast who underwent surgical resection from 2004 to 2017. The prevalence of regional lymph node operation and nodal positivity was calculated. The Kaplan-Meier method was used to evaluate overall survival among node-positive and node-negative patients. Cox proportional hazard modeling was used to evaluate the adjusted association of nodal positivity with overall survival. RESULTS: We included 991 patients with angiosarcoma. The median age was 69 years (interquartile range 57 to 78), and the cohort was 99% female. A total of 298 patients (30%) had pathologic regional nodal evaluation. Of those, 15 (5.0%) had positive regional lymph nodes. Node-positive patients had significantly worse survival than patients with negative regional lymph nodes. After adjusting for patient, tumor, and treatment factors, a positive regional lymph node was associated with worse overall survival compared with patients with no nodal evaluation (hazard ratio 3.20; 95% CI 1.75 to 5.86; p < 0.001). CONCLUSIONS: Patients with nonmetastatic angiosarcoma of the breast have a 5% regional lymph node positivity rate, which is at a common threshold to consider evaluation, and identifies patients with poor survival. A prospective study to determine performance characteristics of sentinel lymph node biopsy is warranted.

BACKGROUND: Travel distance to surgical cancer care is increasing. The relationship between increased travel distance and receipt of surgical cancer care in the United States is not well characterized. METHODS: A systematic review of studies examining travel distance and receipt of surgery for adult patients in the United States was performed. Literature searches were conducted using PubMed and EMBASE. RESULTS: Seven studies were included. Only one found lower likelihood of surgery with increasing travel distance. Three studies, all based on hospital-based data, found that increased travel distance was associated with a higher likelihood of receiving surgery. Two studies found no association and one study had mixed findings. CONCLUSION: We were unable to identify a consistent relationship between travel distance and receipt of surgery. Our results highlight the need for additional research examining how increasing travel distance impacts receipt of surgical cancer care.

BACKGROUND: Few studies assess use of parathyroidectomy among older adults with symptomatic primary hyperparathyroidism. Our objective was to determine national usage and disparities in parathyroidectomy for symptomatic primary hyperparathyroidism among insured older adults. METHODS: We identified older adult patients with symptomatic primary hyperparathyroidism using Medicare claims (2006-2017). Primary study variables were race/ethnicity, rurality, and zip-code socioeconomic status. We calculated cumulative incidence of parathyroidectomy and used multivariable Cox proportional hazards regression models to assess the adjusted association of our study variables with parathyroidectomy. RESULTS: We included 94,803 patients. The median age at primary hyperparathyroidism diagnosis was 76 years (interquartile range 71-82). The majority of patients were female (72%), non-Hispanic White (82%), from metropolitan areas (82%), and had a Charlson Comorbidity score ≥3 (62%). Nine percent of patients (n = 8,251) underwent parathyroidectomy during follow-up. After adjustment, non-Hispanic Black patients, compared to non-Hispanic White (hazard ratio 0.80; 95% confidence interval 0.74, 0.87), and living in a low socioeconomic status neighborhood (low socioeconomic status vs highest socioeconomic status hazard ratio 0.89; 95% confidence interval 0.83, 0.95) were both associated with lower incidences of parathyroidectomy. Patients from non-metropolitan areas were more likely to undergo parathyroidectomy. CONCLUSION: Parathyroidectomy is underused for symptomatic primary hyperparathyroidism in older adults. Quality improvement efforts, rooted in equitable care, should be undertaken to increase access to parathyroidectomy for this disease.

BACKGROUND: Racial disparities in opioid prescribing are widely documented, though few studies assess racial differences in the postoperative setting specifically. We hypothesized standard opioid prescribing schedules reduce total opioids prescribed postoperatively and mitigate racial variation in postoperative opioid prescribing. METHODS: This is a retrospective review of adult general surgery cases at a large, public academic institution. Standard opioid prescribing schedules were implemented across general surgery services for common procedures in late 2018 at various timepoints. Interrupted time series analysis was used to compare mean biweekly discharge morphine milligram equivalents prescribed in the preintervention (Jan-Jun 2018) versus postintervention (Jan-Jun 2019) periods for Black and White patients. Linear regression was used to compare mean difference in discharge morphine milligram equivalents among White and Black patients in each study period, while controlling for demographics, chronic opioid use, and procedure/service. RESULTS: A total of 2,961 cases were analyzed: 1,441 preintervention and 1,520 postintervention. Procedural frequencies, proportion of Black patients (17% Black), and chronic opioid exposure (7% chronic users) were similar across time periods. Interrupted time series analysis showed significantly lower mean level of morphine milligram equivalents prescribed postintervention compared with the predicted nonintervention trend for both Black and White patients. Adjusted analysis showed on average in 2018 Black patients received significantly higher morphine milligram equivalents than White patients (+19 morphine milligram equivalents, 95% confidence interval 0.5-36.5). There was no significant difference in 2019 (-8 morphine milligram equivalents, 95% confidence interval -20.5 to 4.6). CONCLUSION: Standard opioid prescribing schedules were associated with the elimination of racial differences in postoperative opioid prescribing after common general surgery procedures, while also reducing total opioids prescribed. We hypothesize standard opioid prescribing schedules may mitigate the effect of implicit bias in prescribing.
