Introduction: As a result of the success of Maryland's full risk capitated payment model experiment (Global Budget Revenue) in constraining healthcare costs, there is momentum for expanding the reach of such models. However, as these models are implemented, studies analyzing their long-term effects suggest unintended spillover effects that may ultimately influence patient experiences. The aim of this study was to determine whether implementation of the GBR was associated with changes in patient experience.

Introduction: On January 1, 2019, in an effort to improve price transparency, the Centers for Medicare and Medicaid Services (CMS) mandated that hospitals display chargemasters and pricing for diagnosis-related groups (DRGs) online. We examined the compliance of the 50 top orthopaedic hospitals, ranked by US News, with CMS's mandate and compared pricing.

Methods: The chargemaster and pricing of DRG codes related to total knee arthroplasty (TKA) and total hip arthroplasty (THA) (469, 470, 461, 462, 466, 467, and 468) were evaluated in the top 50 orthopaedic hospitals in the United States.

Background: While breast surgery is considered a clean case, tissue expander-based breast reconstruction (TE-BR) has infection rates quoted up to 31%, decidedly higher than the typical 1% to 2% rate of surgical site infections. Through multivariate regression, we sought to analyze risk factors that contribute to infections following TE placement.

Methods: A retrospective study reviewed all patients undergoing mastectomy with immediate or delayed TE placement over a 22-month period.

Importance: In 2014, Maryland implemented the all-payer model, a distinct hospital funding policy that applied caps on annual hospital expenditures and mandated reductions in avoidable complications. Expansion of this model to other states is currently being considered; therefore, it is important to evaluate whether Maryland's all-payer model is achieving the desired goals among surgical patients, who are an at-risk population for most potentially preventable complications.

Objective: To examine the association between the implementation of Maryland's all-payer model and the incidence of avoidable complications and resource use among adult surgical patients.

Unlabelled: Despite a growing body of evidence suggesting improved psychosocial well-being and survival after post-mastectomy breast reconstruction (PMBR), rates remain stagnant at approximately 40%. Although PMBR access and utilization have been well reported, there is much less known from the point of view of women who decide not to undergo PMBR. This study uses a mixed methods approach to fill that gap by investigating the patient-level decisions that lead to foregoing PMBR.

Article Synopsis
  • Access to breast reconstruction for women in low-income countries, particularly West Africa, is hindered by significant barriers related to both patient and provider factors.
  • A study surveyed surgeons to identify these barriers, revealing that many felt limited experience, insufficient resources, and lack of patient referrals were the main obstacles.
  • The findings suggest that addressing issues like surgeon expertise, patient awareness, and costs could help improve access to breast reconstruction services in the region.
