ABSTRACT 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.

Purpose: A variety of care pathways are offered to females with chronic pelvic pain (CPP) and pelvic floor myofascial pain (PFMP), which may affect treatment outcomes. This study aims to compare care pathways and describe health care utilization and characteristics of patients with CPP and PFMP referred for physical therapy (PT) at a tertiary care center. Methods: A retrospective cohort analysis was conducted on females with CPP and PFMP referred for PT. Patients received PT, medication management, injection therapy, or a combination of treatments. We collected data on health care utilization, comorbidities of interest, and patient-reported outcome measures (PROMs). Wilcoxon rank-sum tests were used to compare patients with pre- and posttreatment PROM scores. Results: A total of 1172 patients were referred for PT treatment, but 19.5% (n = 229) did not attend any PT sessions, and only 18% (n = 211) of patients attended the recommended number of PT sessions. Comorbid urinary (48.5%, n = 569) and bowel dysfunction (43%, n = 512) were prevalent. Patients consulted with multiple providers. Most patients (57.1%, n = 669) utilized opioid medications. Less than 20% completed both pre-and posttreatment PROMs. Discussion: Care pathways vary widely for the treatment of PFMP. Low adherence to PT and a trend toward greater than 5 subspecialty appointments indicating higher health care utilization reflect the range of inconsistent patient experience likely affecting outcomes. Outcomes of care are uncharted territory. Optimal care pathways for CPP and PFMP need to be established, along with further investigation of PROMs, to determine which treatments result in effective outcomes that matter to patients.

Nonmedical stimulant use (NMSU) among adolescents poses significant public health concerns. Using cross-sectional design, this study examined risk and protective factors for NMSU among 20,576 Florida high school students using the 2020 Florida Youth Substance Abuse Survey, with 925 students reporting NMSU. Guided by Hawkins and Catalano’s Social Development Model, we employed multivariate logistic regression analyses to estimate adjusted odds ratios while controlling for demographics. Students engaged in extracurricular activities were 50% less likely to report NMSU. Higher academic performance was associated with lower NMSU likelihood. Students with friends who used stimulants nonmedically were significantly more likely to engage in NMSU (AOR, 7.60; 95% CI: 6.35, 9.10), as were those living with relatives who used substances (AOR, 3.54; 95% CI: 2.94, 4.26). Findings highlight the importance of extracurricular involvement and positive social networks in mitigating NMSU. Interventions addressing family, peers, and extracurricular involvement are crucial for prevention and evidence-based policies.

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 .

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.

Background: Addressing social determinants of health in patient care helps hospitals better understand the non-medical factors influencing patients’ health outcomes. Objectives: The objective of this study was to evaluate the correlation between hospital characteristics, county determinants, and the systematic recording of health-related social needs among general and surgical acute care hospitals in the United States. It focused on the hospital’s routine collection of data on patients’ health-related social needs, such as transportation, housing, and food insecurity. Design: A cross-sectional retrospective study design was utilized. Methods: All hospitals that completed the American Hospital Association Annual survey (n = 2254) were included in the study. A series of multinomial logistic analyses were conducted. Results: The relative risk of hospitals routinely collecting health-related social needs data is 67% lower in for-profit hospitals and 90% higher in not-for-profit hospitals compared to government hospitals. Hospitals that are part of a system are 1.5 times more likely to routinely collect data on social needs. In addition, counties with higher household income have a statistically significant higher relative risk of hospitals collecting data on social needs, though the magnitude of the difference is small. The relative risk of hospitals collecting social needs data, but not routinely, is 2 times higher in teaching hospitals and 3 times higher among system hospitals. Conclusion: Our research strongly indicates that understanding and addressing these inherent hospital-related factors are essential for effectively integrating social determinants of health into routine healthcare data collection practices. Establishing more robust guidelines and standardization in these practices may enhance hospitals’ ability to document and utilize health-related social needs information, ultimately driving improved patient outcomes and supporting more equitable care.

Objectives: Surgical site infections (SSIs) are the most common hospital-acquired infections in the United States, of which methicillin-resistant Staphylococcus aureus (MRSA) accounts for 43%. Preoperative povidone-iodine nasal swab (PNS) is considered an effective and cost-saving treatment for Staphylococcus aureus decolonization. We aim to assess the impact of preoperative PNS on SSI incidence. Materials and Methods: This retrospective observational study utilized elective surgical cases between January 1, 2018 and May 31, 2023, at a single academic medical center. The cohort was divided into PNS and no PNS groups. The cohort was propensity-matched, and Pearson χ2/Kruskal-Wallis tests were performed to compare group differences. Multivariable logistic regression was utilized to compare events between cohorts before and after matching. An alpha of <0.05 was considered significant. Results: A total of 45,998 (22,999 per group) matched participants were evaluated. On multivariate regression, the non-PNS treatment group was associated with an increase in hospital overall SSI occurrence (OR: 1.48, P = 0.02) but not specifically in-hospital methicillin-sensitive Staphylococcus aureus SSI, MRSA-SSI, or any 30-day SSI (P > 0.05). Compared with PNS treatment and prophylactic antibiotics, in-hospital SSI was higher in the absence of PNS treatment (OR: 1.83, P < 0.001), antibiotic (OR: 2.63, P < 0.001), or both (OR: 2.06, P < 0.01). Compared with PNS treatment plus prophylactic antibiotic, in-hospital MRSA-SSI was only higher in the absence of antibiotic (OR: 2.92, P < 0.01) treatment. Conclusions: Preoperative treatment with PNS may reduce overall in-hospital SSI but has no independent impact on MRSA SSI.
