Small Business Support Is Associated with the Quantity, Quality, and Usage of Youth Physical Activity Opportunities in Urban, Low-Income, African American Neighborhoods.

Evidence suggests small businesses could play a significant role in bringing quality youth physical activity opportunities (YPAOs) to urban areas. Knowing more about their involvement with YPAOs in African American neighborhoods would be of significant value given the relatively low PA rates of African American youth. The current study examined associations between small businesses and YPAOs in low-income, African American urban neighborhoods. Surveys were conducted with 46.4% (n = 223) of eligible small business owners/managers and 44.2% (n = 38) of eligible YPAO providers in 20 low-income, African American urban neighborhoods to ascertain business and YPAO characteristics. Audits were conducted at the YPAOs and parks (n = 28) in the study areas to obtain counts of users and data on amenities/incivilities. Analyses included multiple linear regression. Only 33.6% of all businesses were currently supporting YPAOs. The percentage of businesses supporting only local YPAOs (YPAOs near the business) was significantly associated with the number of YPAOs in the area, number of YPAO amenities, youth participants, teams, amenity quality, and the severity of incivilities after controlling for neighborhood demographics. Businesses supporting only local YPAOs were at their location longer, and their owners were more likely to have a sports background, children, and believe small businesses should support YPAOs than business not supporting local YPAOs. This study provides evidence that YPAOs in low-income, African American urban neighborhoods are improved by support from small businesses. Efforts to enhance PA among African American youth living in low-income urban neighborhoods could benefit from involving small businesses.

Intraoperative Pancreatic Neck Margin Assessment During Pancreaticoduodenectomy for Pancreatic Adenocarcinoma in the Era of Neoadjuvant Therapy: A Multi-institutional Analysis from the Central Pancreatic Consortium.

BACKGROUND: Data regarding the survival impact of converting frozen-section (FS):R1 pancreatic neck margins to permanent section (PS):R0 by additional resection (i.e., converted-R0) during upfront pancreaticoduodenectomy for pancreatic ductal adenocarcinoma (PDAC) are conflicting. The impact of neoadjuvant therapy on this practice and its relationship with overall survival (OS) is incompletely understood. METHODS: We reviewed PDAC patients (80% borderline resectable/locally advanced [BR/LA]) undergoing pancreaticoduodenectomy after neoadjuvant therapy at seven, academic, high-volume centers (2010-2018). Multivariable models examined the association of PS:R0, PS:R1, and converted-R0 margins with OS. RESULTS: Of 272 patients receiving at least 2 (median 4) cycles of neoadjuvant chemotherapy (71% mFOLFIRINOX or gemcitabine/nab-paclitaxel) and undergoing pancreaticoduodenectomy with intraoperative frozen-section assessment of the transected pancreatic neck margin, PS:R0 (n = 220, 80.9%) was observed in a majority of patients; 18 patients (6.6%) had converted-R0 margins following additional resection, whereas 34 patients (12.5%) had persistently positive PS:R1 margins. At a median follow-up of 42 months, PS:R0 resection was associated with improved OS compared with either converted-R0 or PS:R1 resection (median 25 vs. 14 vs. 16 months, respectively; p = 0.023), with no survival difference between the converted-R0 and PS:R1 groups (p = 0.9). On Cox regression, SMA margin positivity (hazard ratio 2.2, p = 0.012), but not neck margin positivity (hazard ratio 1.2, p = 0.65), was associated with worse OS. CONCLUSIONS: In this multi-institutional cohort of predominantly BR/LA PDAC patients undergoing pancreaticoduodenectomy following modern neoadjuvant therapy, pursuing a negative neck margin intraoperatively if the initial margin is positive does not appear to be associated with improved survival.

Racial and Ethnic Disparities in Breast Cancer Survival: Emergence of a Clinically Distinct Hispanic Black Population.

OBJECTIVE: To understand the impact of Black race on breast cancer (BC) presentation, treatment, and survival among Hispanics. SUMMARY OF BACKGROUND DATA: It is well-documented that non-Hispanic Blacks (NHB) present with late-stage disease, are less likely to complete treatment, and have worse survival compared to their non-Hispanic White (NHW) counterparts. However, no data evaluates whether this disparity extends to Hispanic Blacks (HB) and Hispanic Whites (HW). Given our location in Miami, gateway to Latin America and the Caribbean, we have the diversity to evaluate BC outcomes in HB and HW. METHODS: Retrospective cohort study of stage I-IV BC patients treated at our institution from 2005-2017. Kaplan-Meier survival curves were generated and compared using the log-rank test. Multivariable survival models were computed using Cox proportional hazards regression. RESULTS: Race/ethnicity distribution of 5951 patients: 28% NHW, 51% HW, 3% HB, and 18% NHB. HB were more economically disadvantaged, had more aggressive disease, and less treatment compliant compared to HW. 5-year OS by race/ethnicity was: 85% NHW, 84.8% HW, 79.4% HB, and 72.7% NHB (P < 0.001). After adjusting for covariates, NHB was an independent predictor of worse OS [hazard ratio:1.25 (95% confidence interval: 1.01-1.52), P < 0.041)]. CONCLUSIONS: In this first comprehensive analysis of HB and HW, HB have worse OS compared to HW, suggesting that race/ethnicity is a complex variable acting as a proxy for tumor and host biology, as well as individual and neighborhood-level factors impacted by structural racism. This study identifies markers of vulnerability associated with Black race and markers of resiliency associated with Hispanic ethnicity to narrow a persistent BC survival gap.

The pitfalls of inguinal herniorrhaphy: Surgeon volume matters.

BACKGROUND: There is currently little information regarding the impact of procedure volume on outcomes after open inguinal hernia repair in the United States. Our hypothesis was that increasing procedure volume is associated with lesser rates of reoperation and resource use. METHODS: The database of the Statewide Planning and Research Cooperative System was queried for elective open initial inguinal hernia repairs performed in New York State from 2001 to 2008 via the use of International Classification of Diseases, 9th Revision and Current Procedural Terminology codes. Surgeon and hospital procedure volumes were grouped into tertiles based on the number of open inguinal hernia repairs performed per year. Bivariate, hierarchical mixed effects Cox proportional-hazards, and negative binomial regression analyses were performed assessing for factors associated with reoperation for recurrence, procedure time, and downstream total charges. RESULTS: Among 151,322 patients who underwent open inguinal hernia repair, the overall rate of reoperation for recurrence within 5 years was 1.7% with a median time to reoperation of 1.9 years. An inverse relationship was seen between surgeon volume and reoperation rate, procedure time, and health care costs (P < .001). After we controlled for surgeon, facility, operative and patient characteristics, low-volume surgeons (<25 repairs/year) had greater rates of reoperation (hazard ratio 1.23,95% confidence interval [95% CI] 1.11-1.36), longer procedure times (incidence rate ratio 1.22, 95% CI 1.21-1.24), and greater downstream costs (incidence rate ratio 1.13,95% CI 1.10-1.17) than high-volume surgeons (≥25 repairs/year). CONCLUSION: Surgeon volume <25 cases per year for open inguinal hernia repair was independently associated with greater rates of reoperation for recurrence, worse operative efficiency, and greater health care costs. Referral to surgeons who perform ≥25 inguinal hernia repairs per year should be considered to decrease reoperation rates and resource use.

Surgeon volume plays a significant role in outcomes and cost following open incisional hernia repair.

TITLE: Surgeon Volume Plays a Significant Role in Outcomes and Cost Following Open Incisional Hernia Repair PURPOSE: Incisional hernia is a common complication following gastrointestinal surgery. Many surgeons elect to perform incisional hernia repairs despite performing only limited numbers of hernia repairs annually. This study examines the relationship between surgeon/facility volume and operative time, reoperation rates, and cost following initial open hernia repair. METHODS: The New York Statewide Planning and Research Cooperative System was queried for elective open initial incisional hernias repairs from 2001 to 2006. Surgeon/facility volumes were calculated as mean number of open incisional hernia repairs per year from 2001 to 2006. Reoperations for recurrent hernia over a 5-year period were identified using ICD-9/CPT codes. Multivariable regression was used to compare patient, surgeon, and facility characteristics with operative time, hernia reoperation, and hospital charges. RESULTS: Eighteen thousand forty-seven patients met the inclusion criteria. The hernia reoperation rate was 9%, and median time to reoperation was 1.4 years (mean = 1.8). After adjusting for clinical factors, surgeons performing an average of ≥36 repairs/year had significantly lower reoperation rates (HR = 0.59, 95% confidence interval (CI) = 0.48,0.72), operative time (incidence rate ratio (IRR) = 0.67, 95% CI = 0.64,0.71), and downstream charges (IRR = 0.63, 95% CI = 0.57,0.69). Facility characteristics (volume, academic affiliation, location) were not associated with reoperation. CONCLUSIONS: This study found a strong association between individual surgeon incisional hernia repair volume and hernia reoperation rates, operative efficiency, and charges. Preferential referral to high-volume surgeons may lead to improved outcomes and lower costs.

Defining high risk: cost-effectiveness of extended-duration thromboprophylaxis following major oncologic abdominal surgery.

PURPOSE: Extended-duration thromboprophylaxis (EDTPPX) is the practice of prescribing antithrombotic therapy for 21 days after discharge, commonly used in surgical patients who are at high risk for venothromboembolism (VTE). While guidelines recommend EDTPPX, criteria are vague due to a paucity of data. The criteria can be further informed by cost-effectiveness thresholds. This study sought to determine the VTE incidence threshold for the cost-effectiveness of EDTPPX compared to inpatient prophylaxis. METHODS: A decision tree was used to compare EDTPPX for 21 days after discharge to 7 days of inpatient prophylaxis with base case assumptions based on an abdominal oncologic resection without complications in an otherwise healthy individual. Willingness to pay was set at $50,000/quality-adjusted life year (QALY). Sensitivity analyses were performed to assess uncertainty within the model, with particular interest in the threshold for cost-effectiveness based on VTE incidence. RESULTS: EDTPPX was the dominant strategy when VTE probability exceeds 2.39 %. Given a willingness to pay threshold of $50,000/QALY, EDTPPX was the preferred strategy when VTE incidence exceeded 1.22 and 0.88 % when using brand name or generic medication costs, respectively. CONCLUSIONS: EDTPPX should be recommended whenever VTE incidence exceeds 2.39 %. When post-discharge estimated VTE risk is 0.88-2.39 %, patient preferences about self-injections and medication costs should be considered.

Resident involvement is associated with worse outcomes after major lower extremity amputation.

BACKGROUND: Despite the recent major changes in vascular and general surgery training, there has been a paucity of literature examining the effect of these changes on training and surgical outcomes. Amputations represent a common cross-section in core competencies for general surgery and vascular surgery trainees. This study evaluates the effect of trainee participation on outcomes after above-knee and below-knee amputations. METHODS: The American College of Surgeons-National Surgical Quality Improvement Program (NSQIP) database (2005 to 2010) was queried using Current Procedural Terminology codes (American Medical Association, Chicago, Ill) for below-knee amputation (27880, 27882) and above knee-amputation (27590, 27592). Resident involvement was defined using the NSQIP variable and was narrowed to postgraduate year 1 to 5. Variables associated with resident involvement were identified, and mortality, morbidity, intraoperative transfusion, and operative time (75th percentile vs the bottom three quartiles) were evaluated as distinct categoric end points in logistic regression. Included in the model were variables with a P value <.1 on χ(2) or independent t-test, as appropriate. Significance was defined at P < .05. RESULTS: Residents were involved in 6587 of 11,038 amputations (62%). After adjustment for preoperative and intraoperative factors on logistic regression, there was a significant increase in major morbidity (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.14-1.42; P < .001), intraoperative transfusion (OR, 1.78; 95% CI, 1.50-2.11; P < .001), and operative time (OR, 1.64 95% CI, 1.46-1.84; P < .001) in resident cases. CONCLUSIONS: Resident involvement was associated with increased odds of major morbidity after amputation and also with increased operative time and risk for intraoperative transfusions.
