Large Language Model Influence on Diagnostic Reasoning: A Randomized Clinical Trial.
Large Lanuguage Models may outperform physicians on diagnostic tasks, but simply providing access to AI tools does not improve doctors' diagnostic reasoning without effective integration.

To improve health care price transparency and promote cost-conscious selection of health care organizations and practitioners, the Centers for Medicare & Medicaid Services (CMS) required that hospitals share payer-specific negotiated prices for selected shoppable health services by January 2021. While this regulation improves price transparency, it is unclear whether disclosed prices reflect total costs of care, since many hospital-based services are delivered and billed separately by independent practitioners or other health care entities. ⋯ This cross-sectional study found that independent practitioners were frequently involved in the delivery of shoppable hospital-based care, and their reimbursement may have represented a substantial portion of total costs of care. These findings suggest that disclosed hospital reimbursement was usually not correlated with total cost of care, limiting the potential benefits of the hospital price transparency rule for improving consumer decision-making.

Increasing hospital costs for bronchiolitis have been associated with increasing patient complexity and mechanical ventilation. However, the associations of illness severity and diagnostic coding practices with bronchiolitis hospitalization costs have not been examined. ⋯ This cross-sectional study suggests that hospitalized children with bronchiolitis are receiving costlier and more intensive care without objective evidence of increasing severity of illness. Changes in coding practices may complicate efforts to study trends in the use of health care resources using administrative data.

The use of acellular dermal matrix (ADM) in implant-based breast reconstructions (IBBRs) is established practice. Existing evidence validating ADMs proposed advantages, including improved cosmetics and more single-stage IBBRs, is lacking. ⋯ Immediate IBBR with ADM did not yield fewer reoperations compared with conventional IBBR without ADM, nor was IBBR with ADM superior in terms of HRQoL or patient-reported cosmetic outcomes. Patients treated for breast cancer contemplating ADM-supported IBBR should be informed about the lack of evidence validating ADM's suggested benefits.
