Trends in outpatient dermatology appointment wait times for United States (US) veterans are poorly characterized. Given concerns surrounding prolonged wait times at Veterans Health Administration (VHA) medical facilities, the federal government introduced the Maintaining Internal Systems and Strengthening Outside Networks (MISSION) Act in 2018, allowing veterans to receive VHA-reimbursed community care if VHA specialty care appointments cannot be scheduled within 28 days. Considering this expanded access to community care, we characterized among US veterans the (1) overall demand for dermatology appointments, (2) trends in average wait times, and (3) facility/geographic variation in wait times.

Introduction: Acute otitis media is one of the most common reasons for pediatric medical visits in the United States. Additionally, past studies have linked food insecurity and malnutrition with increased infections and worse health outcomes. However, there is a lack of information on the risk factors for food insecurity in specific patient populations, including the pediatric recurrent acute otitis media (RAOM) population.

Background: The Veterans Health Administration has been criticized for long wait times; however, studies indicate that Veterans Health Administration wait times are shorter than those for the Veterans Health Administration's Community Care Program. Previous studies have analyzed primary care wait times, but few have compared surgical specialties.

Methods: Using a publicly available data set of veteran appointments compiled from the Veterans Health Administration's Corporate Data Warehouse, a nationally representative database containing 623,868 surgical consults from January 1 to June 30, 2021, mean differences in wait times between the Veterans Health Administration and the Community Care Program were calculated across surgical specialties.

Sentinel lymph node biopsy (SLNB) is an important staging and prognostic tool for cutaneous melanoma (CM). However, there exists a knowledge gap regarding whether sociodemographic characteristics are associated with receipt of SLNB for T1b CMs, for which there are no definitive recommendations for SLNB per current National Comprehensive Cancer Network guidelines. We performed a retrospective analysis of the 2012-2018 National Cancer Database, identifying patients with American Joint Committee on Cancer staging manual 8th edition stage T1b CM, and used multivariable logistic regression to analyze associations between sociodemographic characteristics and receipt of SLNB.

Objective: To project the number and proportion of women in the urology workforce using recent demographic trends and develop an app to explore updated projections using future data.

Methods: Demographic data were obtained from AUA Censuses and ACGME Data Resource Books. The proportion of female graduating urology residents was characterized with a logistic growth model.

Purpose: The Merit-Based Incentive Payment System (MIPS) is currently the only federally mandated value-based payment model for oncologists. The weight of cost measures in MIPS has increased from 0% in 2017 to 30% in 2022. Given that cost measures are specialty-agnostic, specialties with greater costs of care such as oncology may be unfairly affected.

Background: Although biomedical preprint servers have grown rapidly over the past several years, the harm to patient health and safety remains a major concern among several scientific communities. Despite previous studies examining the role of preprints during the Coronavirus-19 pandemic, there is limited information characterizing their impact on scientific communication in orthopaedic surgery.

Questions/purposes: (1) What are the characteristics (subspecialty, study design, geographic origin, and proportion of publications) of orthopaedic articles on three preprint servers? (2) What are the citation counts, abstract views, tweets, and Altmetric score per preprinted article and per corresponding publication?

Methods: Three of the largest preprint servers (medRxiv, bioRxiv, and Research Square) with a focus on biomedical topics were queried for all preprinted articles published between July 26, 2014, and September 1, 2021, using the following search terms: "orthopaedic," "orthopedic," "bone," "cartilage," "ligament," "tendon," "fracture," "dislocation," "hand," "wrist," "elbow," "shoulder," "spine," "spinal," "hip," "knee," "ankle," and "foot.

Article Synopsis
  • * It aims to determine the percentage of orthopaedic surgeons who leave active clinical practice within their first 10 years and to identify which personal and practice-related factors contribute to this early-career attrition.
  • * The study analyzes a large database of surgeons from the Physician Compare National Downloadable File, including 18,107 orthopaedic surgeons, with a specific focus on a subset of 4,853 surgeons who have recently completed their training.

Article Synopsis
  • Metastatic spinal melanoma is a rare and aggressive condition with a generally unfavorable prognosis, closely linked to traditional cutaneous melanoma demographics.
  • Treatment often includes decompressive surgery and radiotherapy, with newer techniques like stereotactic radiosurgery showing promise; however, survival rates have improved recently due to immune checkpoint inhibitors used alongside surgery and radiotherapy.
  • Ongoing research is vital, especially for patients unresponsive to immunotherapy, to identify the best treatment strategies through high-quality prospective data from randomized controlled trials.

The merit-based incentive payment system (MIPS) is a value-based payment model created by the Centers for Medicare & Medicaid Services (CMS) to promote high-value care through performance-based adjustments of Medicare reimbursements. In this cross-sectional study, we examined the participation and performance of oncologists in the 2019 MIPS. Oncologist participation was low (86%) compared to all-specialty participation (97%).

Background: The economic burden of traumatic injuries forces families into difficult tradeoffs between healthcare and nutrition, particularly among those with a low income. However, the epidemiology of food insecurity among individuals reporting having experienced fractures is not well understood.

Questions/purposes: (1) Do individuals in the National Health Interview Survey reporting having experienced fractures also report food insecurity more frequently than individuals in the general population? (2) Are specific factors associated with a higher risk of food insecurity in patients with fractures?

Methods: This retrospective, cross-sectional analysis of the National Health Interview Survey was conducted to identify patients who reported a fracture within 3 months before survey completion.

Article Synopsis
  • The study examines trends in total hip arthroplasty (THA) procedures, focusing on patient access and changes in surgeon availability between 2013 and 2019.
  • Data from Medicare's provider utilization and payment files were analyzed to compare the number of primary THA and revision THA (revTHA) surgeons across different geographic regions.
  • Results showed an increase in primary THA surgeons by 17.6%, while revTHA surgeons decreased by 36.1%, indicating a negative impact on patient access for revision procedures, likely due to economic factors.

Given limited information about patient experiences with cultural competency within dermatology, we sought to characterize the perception of culturally competent care among skin cancer patients in the United States. We used the 2017 National Health Interview Survey (NHIS) to identify a sample of patients with skin cancer and analyzed responses to the following questions: "How important is it for providers to understand or share your culture?" and "How often are you able to see health care providers that understand or share your culture?" For each question, we calculated the overall prevalence along with adjusted odds ratios for each sociodemographic group. Overall, 31% (95% CI 27-35%) of skin cancer patients responded that it was very or somewhat important for providers to share/understand culture.

Background: While the burden of revision total joint arthroplasty (TJA) procedures increases within the United States, it is unclear whether health care resource allocation for these complex cases has kept pace. This study examined the trends in hospital-level reimbursements for revision TJA hospitalizations.

Methods: The Centers for Medicare and Medicaid Services (CMS) inpatient utilization and payment public use files from 2014 to 2019 were queried for diagnostic-related groups (DRGs) for revision TJA: DRG 467 (revision of hip or knee arthroplasty with complication or comorbidity [CC]) and DRG 468 (revision of hip or knee arthroplasty without CC or major CC).
