RESUMO

Importance: Evaluating how social determinants of health (SDOH) influence veteran outcomes is crucial, particularly for quality improvement. Objective: To measure associations between SDOH, care fragmentation, and surgical outcomes using a Desirability of Outcome Ranking (DOOR). Design, Setting, And Participants: This was a cohort study of US veterans using data from the Veterans Affairs (VA) Surgical Quality Improvement Program (VASQIP; 2013-2019) limited to patients aged 65 years or older with inpatient stays between 2 and 30 days, merged with multiple data sources, including Medicare. Race and ethnicity data were retrieved from VASQIP, Medicare and Medicaid beneficiary summary files, the Veterans Health Administration Corporate Data Warehouse, and the United States Veterans Eligibility Trends and Statistics file. Data were analyzed between September 2023 and February 2024. Exposure: Living in a highly deprived neighborhood (Area Deprivation Index >85), race and ethnicity used as a social construct, rurality, and care fragmentation (percentage of non-VA care days). Main Outcomes and Measures: DOOR is a composite, patient-centered ranking of 26 outcomes ranging from no complication (1, best) to 90-day mortality or near-death complications (6, worst). A series of proportional odds regressions was used to assess the impact of SDOH and care fragmentation adjusted for clinical risk factors, including presentation acuity (presenting with preoperative acute serious conditions and urgent or emergent surgical procedures). Results: The cohort had 93 644 patients (mean [SD] age, 72.3 [6.2] years; 91 443 [97.6%] male; 74 624 [79.7%] White). Veterans who identified as Black (adjusted odds ratio [aOR], 1.06; 95% CI, 1.02-1.10; P = .048) vs White and veterans with higher care fragmentation (per 20% increase in VA care days relative to all care days: aOR, 1.01; 95% CI, 1.01-1.02; P < .001) were associated with worse (higher) DOOR scores until adjusting for presentation acuity. Living in rural geographic areas was associated with better DOOR scores than living in urban areas (aOR, 0.93; 95% CI, 0.91-0.96; P < .001), and rurality was associated with lower presentation acuity (preoperative acute serious conditions: aOR, 0.88; 95% CI, 0.81-0.95; P = .001). Presentation acuity was higher in veterans identifying as Black, living in deprived neighborhoods, and with increased care fragmentation. Conclusions and Relevance: Veterans identifying as Black and veterans with greater proportions of non-VA care had worse surgical outcomes. VA programs should direct resources to reduce presentation acuity among Black veterans, incentivize veterans to receive care within the VA where possible, and better coordinate veterans' treatment and records between care sources.

RESUMO

Importance: Insurance coverage expansion has been proposed as a solution to improving health disparities, but insurance expansion alone may be insufficient to alleviate care access barriers. Objective: To assess the association of Area Deprivation Index (ADI) with postsurgical textbook outcomes (TO) and presentation acuity for individuals with private insurance or Medicare. Design, Setting, and Participants: This cohort study used data from the National Surgical Quality Improvement Program (2013-2019) merged with electronic health record data from 3 academic health care systems. Data were analyzed from June 2022 to August 2023. Exposure: Living in a neighborhood with an ADI greater than 85. Main Outcomes and Measures: TO, defined as absence of unplanned reoperations, Clavien-Dindo grade 4 complications, mortality, emergency department visits/observation stays, and readmissions, and presentation acuity, defined as having preoperative acute serious conditions (PASC) and urgent or emergent cases. Results: Among a cohort of 29 924 patients, the mean (SD) age was 60.6 (15.6) years; 16 424 (54.9%) were female, and 13 500 (45.1) were male. A total of 14 306 patients had private insurance and 15 618 had Medicare. Patients in highly deprived neighborhoods (5536 patients [18.5%]), with an ADI greater than 85, had lower/worse odds of TO in both the private insurance group (adjusted odds ratio [aOR], 0.87; 95% CI, 0.76-0.99; P = .04) and Medicare group (aOR, 0.90; 95% CI, 0.82-1.00; P = .04) and higher odds of PASC and urgent or emergent cases. The association of ADIs greater than 85 with TO lost significance after adjusting for PASC and urgent/emergent cases. Differences in the probability of TO between the lowest-risk (ADI ≤85, no PASC, and elective surgery) and highest-risk (ADI >85, PASC, and urgent/emergent surgery) scenarios stratified by frailty were highest for very frail patients (Risk Analysis Index ≥40) with differences of 40.2% and 43.1% for those with private insurance and Medicare, respectively. Conclusions and Relevance: This study found that patients living in highly deprived neighborhoods had lower/worse odds of TO and higher presentation acuity despite having private insurance or Medicare. These findings suggest that insurance coverage expansion alone is insufficient to overcome health care disparities, possibly due to persistent barriers to preventive care and other complex causes of health inequities.

RESUMO

BACKGROUND: Talimogene laherparepvec (T-VEC) is an FDA-approved oncolytic herpesvirus therapy used for unresectable stage IIIB through IV metastatic melanoma. However, the correlation between clinical complete response (cCR) and pathologic complete response (pCR) in patients treated with T-VEC is understudied. STUDY DESIGN: We conducted a retrospective study from a prospectively maintained IRB-approved melanoma single-center database in patients treated with T-VEC from October 2015 to April 2022. Patients were categorized into 3 groups: cCR with pCR, cCR without pCR, and less than cCR. The primary endpoint was overall survival. We used descriptive statistics, chi-square tests, and Wilcoxon rank-sum tests to compare key covariates among exposure groups. We used survival analysis to compare survival curves and reported hazard ratio of death (95% CI) across exposure groups. RESULTS: We included 116 patients with a median overall survival (interquartile range) of 22.7 (14.8-39.3) months. The majority were men (69%) and White (97.4%), with a median age of 74.5 years. More than half of patients (n = 60, 51.6%) achieved cCR. Distribution among the groups was as follows: cCR with pCR (35.3%), cCR without pCR (16.3%), and less than cCR (48.4%). Median overall survival time (interquartile range) was 26.5 (18.6-36.0) months for cCR with pCR, 22.7 (14.4-35.5) months for cCR without pCR, and 17.8 (9.2-47.0) months for less than cCR (log-rank p value = 0.0033). CONCLUSIONS: Patients achieving cCR with pCR after T-VEC therapy have the most favorable overall survival outcomes, whereas those achieving cCR without pCR have inferior survival and those achieving less than cCR have the poorest overall survival outcomes. These findings emphasize the importance of histological confirmation and provide insights for optimizing T-VEC therapy in patients with advanced melanoma.

RESUMO

OBJECTIVE: Develop an ordinal Desirability of Outcome Ranking (DOOR) for surgical outcomes to examine complex associations of Social Determinants of Health. BACKGROUND: Studies focused on single or binary composite outcomes may not detect health disparities. METHODS: Three health care system cohort study using NSQIP (2013-2019) linked with EHR and risk-adjusted for frailty, preoperative acute serious conditions (PASC), case status and operative stress assessing associations of multilevel Social Determinants of Health of race/ethnicity, insurance type (Private 13,957; Medicare 15,198; Medicaid 2835; Uninsured 2963) and Area Deprivation Index (ADI) on DOOR and the binary Textbook Outcomes (TO). RESULTS: Patients living in highly deprived neighborhoods (ADI>85) had higher odds of PASC [adjusted odds ratio (aOR)=1.13, CI=1.02-1.25, P <0.001] and urgent/emergent cases (aOR=1.23, CI=1.16-1.31, P <0.001). Increased odds of higher/less desirable DOOR scores were associated with patients identifying as Black versus White and on Medicare, Medicaid or Uninsured versus Private insurance. Patients with ADI>85 had lower odds of TO (aOR=0.91, CI=0.85-0.97, P =0.006) until adjusting for insurance. In contrast, patients with ADI>85 had increased odds of higher DOOR (aOR=1.07, CI=1.01-1.14, P <0.021) after adjusting for insurance but similar odds after adjusting for PASC and urgent/emergent cases. CONCLUSIONS: DOOR revealed complex interactions between race/ethnicity, insurance type and neighborhood deprivation. ADI>85 was associated with higher odds of worse DOOR outcomes while TO failed to capture the effect of ADI. Our results suggest that presentation acuity is a critical determinant of worse outcomes in patients in highly deprived neighborhoods and without insurance. Including risk adjustment for living in deprived neighborhoods and urgent/emergent surgeries could improve the accuracy of quality metrics.

RESUMO

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.

RESUMO

Objective: Assess associations of Social Determinants of Health (SDoH) using Area Deprivation Index (ADI), race/ethnicity and insurance type with Textbook Outcomes (TO). Summary Background Data: Individual- and contextual-level SDoH affect health outcomes, but only one SDoH level is usually included. Methods: Three healthcare system cohort study using National Surgical Quality Improvement Program (2013-2019) linked with ADI risk-adjusted for frailty, case status and operative stress examining TO/TO components (unplanned reoperations, complications, mortality, Emergency Department/Observation Stays and readmissions). Results: Cohort (34,251 cases) mean age 58.3 [SD=16.0], 54.8% females, 14.1% Hispanics, 11.6% Non-Hispanic Blacks, 21.6% with ADI>85, and 81.8% TO. Racial and ethnic minorities, non-Private insurance, and ADI>85 patients had increased odds of urgent/emergent surgeries (aORs range: 1.17-2.83, all P<.001). Non-Hispanic Black patients, ADI>85 and non-Private insurances had lower TO odds (aORs range: 0.55-0.93, all P<.04), but ADI>85 lost significance after including case status. Urgent/emergent versus elective had lower TO odds (aOR=0.51, P<.001). ADI>85 patients had higher complication and mortality odds. Estimated reduction in TO probability was 9.9% (CI=7.2%-12.6%) for urgent/emergent cases, 7.0% (CI=4.6%-9.3%) for Medicaid, and 1.6% (CI=0.2%-3.0%) for non-Hispanic Black patients. TO probability difference for lowest-risk (White-Private-ADI≤85-elective) to highest-risk (Black-Medicaid-ADI>85-urgent/emergent) was 29.8% for very frail patients. Conclusion: Multi-level SDoH had independent effects on TO, predominately affecting outcomes through increased rates/odds of urgent/emergent surgeries driving complications and worse outcomes. Lowest-risk versus highest-risk scenarios demonstrated the magnitude of intersecting SDoH variables. Combination of insurance type and ADI should be used to identify high-risk patients to redesign care pathways to improve outcomes. Risk adjustment including contextual neighborhood deprivation and patient-level SDoH could reduce unintended consequences of value-based programs.

RESUMO

BACKGROUND: Surgical analyses often focus on single or binary outcomes; we developed an ordinal Desirability of Outcome Ranking (DOOR) for surgery to increase granularity and sensitivity of surgical outcome assessments. Many studies also combine elective and urgent procedures for risk adjustment. We used DOOR to examine complex associations of race/ethnicity and presentation acuity. STUDY DESIGN: NSQIP (2013 to 2019) cohort study assessing DOOR outcomes across race/ethnicity groups risk-adjusted for frailty, operative stress, preoperative acute serious conditions, and elective, urgent, and emergent cases. RESULTS: The cohort included 1,597,199 elective, 340,350 urgent, and 185,073 emergent cases with patient mean age of 60.0 ± 15.8, and 56.4% of the surgeries were performed on female patients. Minority race/ethnicity groups had increased odds of presenting with preoperative acute serious conditions (adjusted odds ratio [aORs] range 1.22 to 1.74), urgent (aOR range 1.04 to 2.21), and emergent (aOR range 1.15 to 2.18) surgeries vs the White group. Black (aOR range 1.23 to 1.34) and Native (aOR range 1.07 to 1.17) groups had increased odds of higher/worse DOOR outcomes; however, the Hispanic group had increased odds of higher/worse DOOR (aOR 1.11, CI 1.10 to 1.13), but decreased odds (aORs range 0.94 to 0.96) after adjusting for case status; the Asian group had better outcomes vs the White group. DOOR outcomes improved in minority groups when using elective vs elective/urgent cases as the reference group. CONCLUSIONS: NSQIP surgical DOOR is a new method to assess outcomes and reveals a complex interplay between race/ethnicity and presentation acuity. Combining elective and urgent cases in risk adjustment may penalize hospitals serving a higher proportion of minority populations. DOOR can be used to improve detection of health disparities and serves as a roadmap for the development of other ordinal surgical outcomes measures. Improving surgical outcomes should focus on decreasing preoperative acute serious conditions and urgent and emergent surgeries, possibly by improving access to care, especially for minority populations.

RESUMO

OBJECTIVE: The aim of this study was to expand Operative Stress Score (OSS) increasing procedural coverage and assessing OSS and frailty association with Preoperative Acute Serious Conditions (PASC), complications and mortality in females versus males. SUMMARY BACKGROUND DATA: Veterans Affairs male-dominated study showed high mortality in frail veterans even after very low stress surgeries (OSS1). METHODS: Retrospective cohort using NSQIP data (2013-2019) merged with 180-day postoperative mortality from multiple hospitals to evaluate PASC, 30-day complications and 30-, 90-, and 180-day mortality. RESULTS: OSS expansion resulted in 98.2% case coverage versus 87.0% using the original. Of 82,269 patients (43.8% male), 7.9% were frail/very frail. Males had higher odds of PASC [adjusted odds ratio (aOR) = 1.31, 95% confidence interval (CI) = 1.21-1.41, P < 0.001] and severe/life-threatening Clavien-Dindo IV (CDIV) complications (aOR = 1.18, 95% CI = 1.09-1.28, P < 0.001). Although mortality rates were higher (all time-points, P < 0.001) in males versus females, mortality was similar after adjusting for frailty, OSS, and case status primarily due to increased male frailty scores. Additional adjustments for PASC and CDIV resulted in a lower odds of mortality in males (30-day, aOR = 0.81, 95% CI = 0.71-0.92, P = 0.002) that was most pronounced for males with PASC compared to females with PASC (30-day, aOR = 0.75, 95% CI = 0.56-0.99, P = 0.04). CONCLUSIONS: Similar to the male-dominated Veteran population, private sector, frail patients have high likelihood of postoperative mortality, even after low-stress surgeries. Preoperative frailty screening should be performed regardless of magnitude of the procedure. Despite males experiencing higher adjusted odds of PASC and CDIV complications, females with PASC had higher odds of mortality compared to males, suggesting differences in the aggressiveness of care provided to men and women.

RESUMO

INTRODUCTION: Yentl syndrome describing sex-related disparities has been extensively studied in medical conditions but not after surgery. This retrospective cohort study assessed the association of sex, frailty, presenting with preoperative acute serious conditions (PASC), and the expanded Operative Stress Score (OSS) with postoperative complications, mortality, and failure-to-rescue. METHODS: The National Surgical Quality Improvement Program from 2015 to 2019 evaluating 30-d complications, mortality, and failure-to-rescue. RESULTS: Of 4,860,308 cases (43% were male; mean [standard deviation] age of 56 [17] y), 6.0 and 0.8% were frail and very frail, respectively. Frailty score distribution was higher in men versus women (P < 0.001). Most cases were low-stress OSS2 (44.9%) or moderate-stress OSS3 (44.5%) surgeries. While unadjusted 30-d mortality rates were higher (P < 0.001) in males (1.1%) versus females (0.8%), males had lower odds of mortality (adjusted odds ratio (aOR) = 0.92, 95% confidence interval [CI] = 0.90-0.94, P < 0.001) after adjusting for frailty, OSS, case status, PASC, and Clavien-Dindo IV (CDIV) complications. Males have higher odds of PASC (aOR = 1.33, CI = 1.31-1.35, P < 0.001) and CDIV complications (aOR = 1.13, CI = 1.12-1.15, P < 0.001). Male-PASC (aOR = 0.76, CI = 0.72-0.80, P < 0.001) and male-CDIV (aOR = 0.87, CI = 0.83-0.91, P < 0.001) interaction terms demonstrated that the increased odds of mortality associated with PASC or CDIV complications/failure-to-rescue were lower in males versus females. CONCLUSIONS: Our study provides a comprehensive analysis of sex-related surgical outcomes across a wide range of procedures and health care systems. Females presenting with PASC or experiencing CDIV complications had higher odds of mortality/failure to rescue suggesting sex-related care differences. Yentl syndrome may be present in surgical patients; possibly related to differences in presenting symptoms, patient care preferences, or less aggressive care in female patients and deserves further study.

RESUMO

BACKGROUND: Readmission after colorectal surgery is common and often implies complications for patients and costs for hospitals. Previous works have created predictive models using logistic regression for this outcome but have shown limited accuracy. Machine learning has shown promise in improving predictions by identifying non-linear patterns in data. We sought to create a more accurate predictive model for readmission after colorectal surgery using machine learning. METHODS: Patients who underwent colorectal surgery were identified in the National Quality Improvement Program (NSQIP) database including years 2012-2019 and split into training, validation, and test sets. The primary outcome was readmission within 30 days of surgery. Three types of machine learning models were created, including random forest (RF), gradient boosting (XGB), and neural network (NN). A logistic regression (LR) model was also created for comparison. Model performance was evaluated using area under the receiver operating characteristic curve (AUROC). RESULTS: The dataset included 213,827 patients after application of exclusion criteria. A total of 23,083 (10.8%) of patients experienced readmission. NN obtained an AUROC of 0.751 (95% CI 0.743-0.759), compared with 0.684 (95% CI 0.676-0.693) for LR. RF and XGB performed similarly with AUROCs of 0.749 (95% CI 0.741-0.757) and 0.745 (95% CI 0.737-0.753) respectively. Ileus, index admission length of stay, organ-space surgical site infection present at time of surgery, and ostomy placement were identified as the most contributory variables. CONCLUSIONS: Machine learning approaches outperformed traditional statistical methods in the prediction of readmission after colorectal surgery. After external validation, this improved prediction model could be used to target interventions to reduce readmission rate.

RESUMO

Background & Aims: Given the risk of intestinal resection for Crohn's disease, postoperative treatment may be informed by several risk factors, including resection type. We compared postoperative treatment strategies for Crohn's disease between emergent/urgent versus elective resection. Methods: We identified patients with intestinal resection for Crohn's disease between 2002-2018 using the MarketScan databases. We classified emergent/urgent resections as those occurring after emergency department admission or after the second day of admission. We estimated adjusted risk differences for the association between resection type (emergent/urgent versus elective) and 6-month postoperative medication strategy (biologic monotherapy, biologic combination therapy with an immunomodulator, immunomodulator monotherapy, other non-biologic medication for Crohn's [5-aminosalicylates, antibiotics, corticosteroids], or no medications for Crohn's). Results: During 6 months after resection among 4,187 patients, 23% received biologic monotherapy, 6% received combination therapy, 16% received immunomodulator monotherapy, and 36% received other non-biologics. Compared to elective resection, emergent/urgent resection was associated with more common use of "other non-biologic" medications (risk difference 6.4%; 95% confidence interval [CI] 2.8%, 10.0%), but less common use of biologic monotherapy (risk difference -3.2%; 95% CI -6.2%, -0.1%) and no medications (risk difference -3.6%; 95% CI -6.6%, -0.6%). Conclusions: Although patients with emergent/urgent resection may benefit from more aggressive postoperative therapy, there was evidence that emergent/urgent resection was more associated than elective resection with postoperative use of non-biologics for Crohn's disease. Future studies of treatment patterns and comparative effectiveness of postoperative treatment strategies for Crohn's patients should consider these differences between resection types, which may be important drivers of longer-term outcomes.

RESUMO

Surgical resection is the cornerstone of curative intent therapy for rectal cancer. The introduction of the concept of total mesorectal excision (TME) led to significant decreases in local recurrence. However, TME carries substantial morbidity. The advent of transanal endoscopic techniques, such as transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS), has allowed patients with early-stage disease to be managed with local excision and avoid the morbidity of TME. Advances in surgery such as laparoscopy, robotic surgery, and transanal approaches have also broadened the options for achieving TME. However, there is significant debate within the literature regarding the optimal approach and oncologic outcomes of these modalities.

RESUMO

BACKGROUND: Despite unprecedented changes to undergraduate medical education and the residency selection process during the COVID-19 pandemic, there is little objective evidence on how the pandemic affected match outcomes such as matched applicant characteristics, interview distribution, geographic clustering, and associated costs. We investigated COVID-19's impact on the residency match by comparing surgery applicants' characteristics, interview distribution, and related costs from 2018 to 2020 to 2021. METHODS: Data from the Texas Seeking Transparency in Applications to Residency initiative were analyzed. Descriptive statistics, bivariate testing, and sensitivity analysis were performed to compare matched applicants in surgical specialties from 2018-2020 to 2021. RESULTS: This study included 5,258 applicants who matched into 10 surgical specialties from 2018 to 2021. In 2021, there was a decrease in proportion of students who reported a geographic connection to their matched program (38.4% vs 42.1%; P = .021) and no significant difference in number of interviews attended (mean [SD], 13.1 [6.2] vs 13.3 [4.7]; P = .136) compared to prior years. Applicants in 2021 had more research experiences and fewer honored clerkships (both P < .001), and these associations persisted in sensitivity analysis. Matched applicants in 2021 reported significantly lower total costs associated with the residency application process compared to 2018 to 2020 (mean [SD] $1,959 [1,275] vs $6,756 [4,081]; P < .001). CONCLUSION: Although COVID-19 appeared to result in a reduction in number of honored clerkships, it may have provided more opportunities for students to engage in research. Overall, the adoption of virtual interviews and away rotations may have successfully mitigated some of the adverse consequences of the pandemic on the residency match for surgical specialties.

RESUMO

OBJECTIVE: To determine predictive factors for a successful residency match among general surgery applicants from 2018 to 2021. DESIGN: A retrospective cross-sectional study of general surgery applicants who matched and went unmatched in match years 2018 to 2021. Applicant characteristics, geographic connections to a program, and away rotations were compared among matched and unmatched applicants. SETTING: Data were sourced from the Texas Seeking Transparency in Applications to Residency initiative for general surgery applicants. PARTICIPANTS: All fourth-year medical students applying in the 2018 to 2021 cycles at participating U.S. medical schools were eligible to respond to the Texas Seeking Transparency in Applications to Residency survey. This study included a total of 1,425 general surgery applicants. RESULTS: Of 1,425 general surgery applicants, 88% matched and 12% went unmatched. Significant predictors for a successful match included Step 1 Score ≥237 (odds ratio (OR) 1.59 [95% CI 1.15-2.19]; p = 0.005); Step 2 CK Score ≥252 (OR 1.88 [95% CI 1.36-2.60]; p < 0.001); ≥3 Honored Clerkships (OR 1.84 [95% CI 1.33-2.53]; p < 0.001); Honors in General Surgery Clerkship (OR 1.73 [95% CI 1.33-2.53]; p = 0.001); AOA membership (OR 2.14 [95% CI 1.34-3.42]; p = 0.001); ≥4 abstracts, posters, or publications (OR 1.66 [95% CI 1.20-2.30]; p=0.002); and ≥1 peer-reviewed publications (OR 1.52 [95% CI 1.09-2.12]; p = 0.014). On average, matched applicants completed more away rotations than unmatched applicants (p = 0.004). Overall, 36% of matched applicants reported a geographic connection to the program where they matched. CONCLUSIONS: We found that Step 2 CK score, research productivity, honored clerkships, AOA status, and away rotations are significant predictors for successfully matching into general surgery residency. Medical schools can encourage students to prepare a holistic application incorporating variables quantified in this study in preparation for the Step 1 reporting change.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Early treatment of hepatocellular carcinoma (HCC) is associated with improved survival, but many patients with HCC do not receive therapy. We aimed to examine factors associated with HCC treatment and survival among incident patients with HCC in a statewide cancer registry. MATERIALS AND METHODS: All patients with HCC from 2003 through 2013 were identified in the North Carolina cancer registry. These patients were linked to insurance claims from Medicare, Medicaid, and large private insurers in North Carolina. Associations between prespecified covariates and more advanced HCC stage at diagnosis (ie, multifocal cancer), care at a liver transplant center, and provision of HCC treatment were examined using multivariate logistic regression. A Cox proportional hazards model was developed to assess the association between these factors and survival. RESULTS: Of 1,809 patients with HCC, 53% were seen at a transplant center <90 days from diagnosis, with lower odds among those who were Black (adjusted odds ratio [aOR], 0.54; 95% CI, 0.39-0.74), had Medicare insurance (aOR, 0.35; 95% CI, 0.21-0.59), had Medicaid insurance (aOR, 0.46; 95% CI, 0.28-0.77), and lived in a rural area; odds of transplant center visits were higher among those who had prediagnosis alpha fetoprotein screening (aOR, 1.74; 95% CI, 1.35-2.23) and PCP and gastroenterology care (aOR, 1.66; 95% CI, 1.27-2.18). Treatment was more likely among patients who had prediagnosis gastroenterology care (aOR, 1.68; 95% CI, 0.98-2.86) and transplant center visits (aOR, 2.42; 95% CI, 1.74-3.36). Survival was strongly associated with age, cancer stage, cirrhosis complications, and receipt of HCC treatment. Individuals with Medicare (adjusted hazard ratio [aHR], 1.58; 95% CI, 1.20-2.09) and Medicaid insurance (aHR, 1.55; 95% CI, 1.17-2.05) had shorter survival than those with private insurance. CONCLUSIONS: In this population-based cohort of patients with HCC, Medicare/Medicaid insurance, rural residence, and Black race were associated with lower provision of HCC treatment and poorer survival. Efforts should be made to improve access to care for these vulnerable populations.

RESUMO

BACKGROUND: Melanoma-specific outcomes for Black patients are worse when compared to non-Hispanic white (NHW) patients. We sought to evaluate whether acral lentiginous melanoma, seen more commonly in Black patients, was associated with racial disparities in outcomes METHODS: The National Cancer Database was analyzed for major subtypes of stage I-IV melanoma diagnosed from 2004 to 2016. The association between Black race and (Siegel et al., Jan) 1 acral melanoma diagnosis and (Bradford et al., Apr) 2 receipt of major amputation for surgical management of melanoma was evaluated using multivariable logistic regression. RESULTS: 251,864 patients were included (1453 Black). Black patients had increased odds of acral melanoma (odds ratio [OR] = 27.6, 95% CI]: 24.4, 31.2) compared to NHW patients. Black patients still had higher odds ratios of major amputation across all stages after adjusting for acral histology and other potential confounders CONCLUSIONS: Increased prevalence of acral melanoma in Black patients does not fully account for increased receipt of major amputation.

RESUMO

PURPOSE: Radiation therapy often requires weeks of daily treatment making travel distance a known barrier to care. However, the full extent and variability of travel burden, defined by travel time, across the nation is poorly understood. Additionally, some states restrict radiation oncology (RO) services through Certificate of Need (CON) policies, but it is unknown how this affects travel times to care. Therefore, we aim to evaluate travel times to US RO facilities and assess the association with CON policies. METHODS AND MATERIALS: RO facilities were identified from the 2018 National Plan and Provider Enumeration System (n = 2302). Travel times from populated US census tracts to nearest facility were calculated; differences by rurality, area deprivation, and region were computed. Multivariable linear regression was used to estimate adjusted differences in travel time by area characteristics. Logistic regression was used to assess the association of state CON laws with travel time >1 hour. RESULTS: Among 72,471 census tracts, 92.4% were within 1 hour of the nearest radiation facility. Among the 12,453 rural tracts, 34.4% were >1 hour. On adjusted analysis, the 3054 isolated rural tracts had an estimated 58-minute (95% confidence interval [CI] 57, 59; P < .001) longer travel time than urban tracts. CON laws decreased rural travel time overall, but the association varied by region with decreased odds of prolonged travel in the South (P < .001), increased odds in the Northeast and Midwest (P < .001), and no association in the West (P = NS). CONCLUSIONS: Isolated rural US census tracts, accounting for 9.4 million Americans, have nearly 1-hour longer adjusted travel time to the nearest RO facility, compared with urban tracts. CON laws had region-dependent associations with prolonged travel.
