Background and Objectives: Pancreatic ductal adenocarcinoma (PDAC) remains highly lethal, but the contribution of nonbiological factors to long‐term survival is unclear. We evaluated demographic, socioeconomic, clinical, treatment, and care‐delivery factors associated with 3‐year survival and whether these associations persisted at 5 years. Methods: National Cancer Database patients with stage I–III PDAC diagnosed from 2012 to 2022 were analyzed using multivariable logistic regression adjusted for treatment pathway. Results: Among 57,053 patients, 51,071 were eligible for a 3‐year analysis, and 12,205 (23.9%) survived. Compared with chemotherapy alone, surgery with chemotherapy (OR, 7.12; 95% CI, 6.64–7.63) and surgery alone (OR, 3.84; 95% CI, 3.49–4.23) had the strongest associations with survival. Younger age, lower comorbidity, Asian race, Spanish/Hispanic ethnicity, private insurance, lower grade, body or tail location, and lower nodal burden were independently associated with survival. Black race and treatment timing were not significant after adjustment. Findings were directionally consistent at 5 years. Conclusion: Demographic, socioeconomic, and clinical factors independently influence 3‐year survival in PDAC. These findings underscore the need to complement biologic and therapeutic advances with structural interventions, such as insurance expansion and improved access to high‐quality centers, to mitigate disparities and improve outcomes in this highly lethal cancer.

Purpose: To assess if hospitals with high physician employment differ in risk-standardized mortality and readmission rates. Design/methodology/approach: A cross-sectional evaluation of data from the 2021 Hospital Readmission Reduction program, Hospital Value-Based Purchasing Program, American Hospital Association and Area Health Resource Files was utilized. A binary variable was created to identify hospitals with ≤ 50% or >50% employed physicians. Dependent variables included 30-day mortality and readmission rates for acute myocardial infarction (AMI), congestive heart failure (CHF), pneumonia (PN), and chronic obstructive pulmonary disease (COPD) hospitalizations. Propensity score matching was utilized to compare hospitals. The final matched cohort compared 200 hospitals in each group ( ≤ 50% physicians and > 50% physicians). Findings: After matching, hospitals with > 50% physician employment were associated with improved mortality scores for AMI (−0.36, 95% CI: −0.58, −0.14), COPD (−0.38, 95% CI: −0.63, −0.14), and PN (−0.71, 95% CI: −1.15, −0.27). No significant differences were noted for CHF mortality or readmission rates. Originality/value: There has been a growth in hospitals employing physician in the United States. This work demonstrates that hospitals with higher physician employment levels are associated with lower mortality scores. This likely reflects a broader organizational phenotype characterized by alignment, scale and clinical integration rather than physician employment as an isolated strategy. Further research should examine organizational features to better disentangle the structure and combination of organizational characteristics underlying these associations.

Background The growth rate of robotic bariatric surgery has recently increased compared to prior years. The impact of this new growth rate on duodenal switch procedures (DSPs) remains uncertain. Material and Methods DSPs performed using robotic assistance (RDSPs) or conventional laparoscopy (LDSPs) were identified from the 2015 to 2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) databases. Then, 1:1 matched analysis compared outcomes between all RDSPs and LDSPs, and those performed during different operative periods (2015–2018 and 2019–2021). Results Then, 14,679 DSPs (73.6% LDSPs and 26.4% RDSPs) were analyzed. Matched analyses compared 2081 RDSPs to 2081 LDSPs. Mean operation length (p < 0.001) and hospital length of stay (LOS) (p < 0.001) were longer for RDSPs. The risk of surgical site infection (SSI) (OR 1.37), readmission (OR 1.34), reintervention (OR 1.39), and overall morbidity (OR 1.34) were significantly higher for RDSPs. RDSPs performed between 2015 and 2018 also had longer operative duration and hospital length of stay, but comparable outcomes to LDSPs. In contrast, RDSPs performed from 2019 to 2021 had higher SSI (OR 1.81), readmission (OR 2.02), reintervention (OR 2.08), and overall morbidity (OR 1.8) risk. Operation duration also remains longer for RDSPs, but similar hospital length of stay. Conclusion In this matched analysis, both RDSPs and LDSPs were safe. With bariatric growth, more recently performed RDSPs appear to be associated with an increase in some adverse outcomes.

Background: Orthopaedic surgeons routinely delay surgical management of femoral neck fractures in patients taking direct oral anticoagulants (DOACs) to decrease perioperative bleeding and associated complications. However, this practice contradicts the principles of hip fracture management, as early surgery is associated with morbidity and mortality benefits. The purpose of this study was to quantify the association of DOAC use and perioperative outcomes in patients who underwent hemiarthroplasty (HA) or total hip arthroplasty (THA) for femoral neck fractures. We hypothesized that early surgical intervention on a patient taking a DOAC medication would not lead to worse perioperative outcomes. Methods: A retrospective cohort study was conducted on 2,833 patients who underwent primary THA or HA for femoral neck fractures between December 31, 2017, and January 29, 2024, across our hospital system. The patients taking a DOAC were divided into 3 groups based on the time since the last DOAC intake: 1 day, 2 days, and ≥3 days. Propensity matching was performed 1:1, accounting for age, sex, Elixhauser Comorbidity Index, preoperative chronic kidney disease stage, preoperative hemoglobin, body mass index, and hospital type. Subanalyses utilizing linear and conditional logistic regression models were performed to assess differences in outcomes between the groups that had a DOAC withheld and the control groups. Results: The mean age of all patients was 81 ± 10 years, 1,805 patients (64%) were women, and 207 patients (7%) were taking a DOAC prior to surgery. Despite comparable preoperative and postoperative hemoglobin levels between the groups that had a DOAC withheld and the control groups (all p > 0.05), the patients who had a DOAC withheld for 1 day were more likely to receive a postoperative blood transfusion (23.1% compared with 0%; p = 0.002). This difference in transfusion rate was not observed in other cohorts. There were no differences in medical complications, reoperation, discharge disposition, or mortality between the groups that had a DOAC withheld and the matched controls at any time point. Conclusions: Delaying surgical management due to DOAC medications may be unnecessary in patients undergoing arthroplasty for femoral neck fractures. Consideration should be given to adjusting transfusion triggers to reduce unwarranted blood transfusions in patients taking a DOAC. Level of Evidence: Therapeutic Level III.

This study examined hospital-community partnership effects on 30-day readmission rates across 2,484 U.S. hospitals. Fixed effect linear models analyzed the impact of three partnership types across community strata. In average-to-low need communities, healthcare system partnerships reduced hospital-wide, heart failure, pneumonia, and THA/TKA readmissions, while local agency partnerships reduced hospital-wide, heart failure, and pneumonia rates. In high-need communities, all partnership types significantly decreased COPD and pneumonia readmissions, with community-based partnerships also reducing hospital-wide rates. Healthcare system partnerships showed the strongest effect on COPD reduction (β = -0.56, p < 0.001). These findings suggest partnerships may reduce readmissions, with stronger effects in high-need communities.

Case: We present a 55-year-old woman with a very short transfemoral amputation who underwent osseointegration. We compared gait analyses before and following osseointegration, demonstrating improvements in kinematics. At follow-up, the patient wore the prosthetic for 16 hours and averaged 10,000 steps daily. She achieved her goal of walking the beach with her prosthetic limb and often traveled without an assistive device. Conclusion: This case study of a patient with a very short transfemoral amputation demonstrated continued improvements in gait and significantly increased prosthetic use over time.

Introduction: Melanoma is a deadly type of skin cancer that develops from melanocytes and can manifest on the skin or other regions of the body. Its incidence is increasing rapidly, with approximately 100,000 diagnoses and 7000 deaths per year in the US alone. We conducted a cross-sectional study with the aim of determining an association between the cost of care for invasive melanoma and the specialty involved in the treatment to adequately guide future treatment. Methods: We analyzed data from 3817 patients (2013–2018) using the Florida inpatient/outpatient dataset, CMS cost reports, and the National Plan and Provider Enumeration System. Covariates included age, sex, race/ethnicity, insurance type, region, county rurality, the number of procedures, the comorbidity index, obesity, metastatic cancer presence, hospital size, and physician volume. Multivariable mixed linear regression was used to analyze the data, and the cost was adjusted to the 2019 USD. Results: Dermatology had the largest decrease in the overall and outpatient costs compared to general surgery, followed by plastic surgery. The inpatient costs for dermatology and plastic surgery were lower than those for general surgery, but not significantly so. Conclusions: The costs associated with surgical procedures may vary depending on the specialty of the physician treating the patient. Dermatology was associated with lower treatment costs for invasive melanoma compared to other specialties, indicating that physician specialty influences the cost of care.

Introduction: This study examined simultaneous pancreas–kidney transplant (SPKt) in Black and White patients to identify disparities in transplantation, days on the waitlist, and reasons for SPKt waitlist removal.Methods: Using the United Network for Organ Sharing Standard Transplant Analysis and Research file, patients between January 1, 2009, and May 31, 2021, were included. Three cohorts (overall, SPKt recipients only, and those not transplanted) were selected using propensity score matching. Conditional logistic regression was used for categorical outcomes. Days on the waitlist were compared using negative binomial regression.Results: Black patients had increased odds of receiving a SPKt (OR, 1.25 [95% CI, 1.11–1.40], p < 0.001). White patients had increased odds of receiving a kidney‐only transplant (OR 0.48 [95% CI, 0.38–0.61], p < 0.001), and specifically increased odds of receiving a living donor kidney (OR 0.34 [0.25–0.45], p < 0.001).Conclusion: This study found that Black patients are more likely to receive a SPKt. Results suggest that there are opportunities for additional inquiry related to patient removal from the waitlist, particularly considering White patients received or accepted more kidney‐only transplants and were more likely to receive a living donor kidney‐only transplant.
