Objectives: Healthcare systems increasingly face shortages of medical professionals, and simultaneously experience a rise in demand for healthcare services. In this study, we investigated whether a digital PROM-based monitoring and alert system for hip and knee replacement patients post-surgery can support in decreasing healthcare expenditures and utilization.

Methods: We used data from the randomized controlled trial PROMoting Quality, focusing on 546 hip and 492 knee replacement patients from nine German hospitals between October 2019 and December 2020 with available claims data.

Objectives: To determine whether an AI system can identify breast cancer risk in interval breast cancer (IBC) screening mammograms.

Materials And Methods: IBC screening mammograms from a Swiss screening program were retrospectively analyzed by radiologists/an AI system. Radiologists determined whether the IBC mammogram showed human visible signs of breast cancer (potentially missed IBCs) or not (IBCs without retrospective abnormalities).

Objective: To describe differences in regionalization of hip fracture care and the volume-outcome relationship in five countries.

Study Setting And Design: We conducted a population-based cross-sectional cohort study in Canada, Israel, the Netherlands, Taiwan, and the United States. Within each country, we stratified patients into quintiles based upon the volume of hip fractures in the hospital where they were treated.

Objectives: Hospitals play a major role in generating clinical evidence on new medical technologies. Thus far, the extent of German hospitals' contribution to the evidence base has not been sufficiently investigated. This study aims to: (1) examine the utilization of new medical technologies in German hospitals and its relationship to different hospital characteristics; (2) investigate the participation of German hospitals in research on these technologies and the association between hospital characteristics and research involvement; and (3) investigate the contribution of German hospitals to international research activities, including the levels of evidence of any studies conducted.

Purpose: Breast cancer remains a major global health issue, with mammography screening programs (MSPs) being critical for early detection to improve survival. Interval breast cancers (IBC) are an important quality criterion and have been linked with increased mortality. We aimed to identify risk factors for IBC diagnoses, based on MSP data.

Background: Public reporting is crucial to enhance transparency, accountability, and informed provider choice. Therefore, providing accessible and reliable information on provider performance and activities is key for all healthcare areas and the utilization of information by patients, providers and related audiences.

Objective: This study provides an extensive analysis of public reporting websites across nine high income countries, focusing on five healthcare areas, and aims to understand how these websites support patients in making informed choices about healthcare providers.

Article Synopsis
  • The study focuses on calculating minimal important changes (MICs) for the EQ-5D-3L index score improvements after hip and knee replacements, using a large dataset to assess patient-reported outcome measures.
  • A retrospective analysis of data from over 500,000 surgeries revealed that MICs varied based on patient characteristics like pre-operative health status, depression, and sex.
  • Results indicated that patients with worse pre-operative scores needed larger MICs to notice improvement, with knee replacement patients generally requiring smaller MICs than those undergoing hip replacements.
