Article Abstract
Objective: We aim to assess the effectiveness of a cataract surgery outcome monitoring tool used for continuous quality improvement. The objectives are to study: (1) the quality parameters, (2) the monitoring process followed and (3) the impact on outcomes.
Design And Procedures: In this retrospective observational study we evaluated a quality improvement (QI) method which has been practiced at the focal institution since 2012: internal benchmarking of cataract surgery outcomes (CATQA). We evaluated quality parameters, procedures followed and clinical outcomes. We created tables and line charts to examine trends in key outcomes.
Setting: Aravind Eye Care System, India.
Participants: Phacoemulsification surgeries performed on 718 120 eyes at 10 centres (five tertiary and five secondary eye centres) from 2012 to 2020 were included.
Interventions: An internal benchmarking of surgery outcome parameters, to assess variations among the hospitals and compare with the best hospital.
Outcome Measures: Intraoperative complications, unaided visual acuity (VA) at postoperative follow-up visit and residual postoperative refractive error (within ±0.5D).
Results: Over the study period the intraoperative complication rate decreased from 1.2% to 0.6%, surgeries with uncorrected VA of 6/12 or better increased from 80.8% to 89.8%, and surgeries with postoperative refractive error within ±0.5D increased from 76.3% to 87.3%. Variability in outcome measures across hospitals declined. Additionally, benchmarking was associated with improvements in facilities, protocols and processes.
Conclusion: Internal benchmarking was found to be an effective QI method that enabled the practice of evidence-based management and allowed for harnessing the available information. Continuous improvement in clinical outcomes requires systematic and regular review of results, identifying gaps between hospitals, comparisons with the best hospital and implementing lessons learnt from peers.

Simulated metabolic profiles reveal biases in pathway analysis methods.

Introduction: Initially developed for transcriptomics data, pathway analysis (PA) methods can introduce biases when applied to metabolomics data, especially if input parameters are not chosen with care. This is particularly true for exometabolomics data, where there can be many metabolic steps between the measured exported metabolites in the profile and internal disruptions in the organism. However, evaluating PA methods experimentally is practically impossible when the sample's "true" metabolic disruption is unknown.

For over two decades, the EBMT has updated recommendations on indications for haematopoietic cell transplantation (HCT) practice based on clinical and scientific developments in the field. This is the ninth special EBMT report on indications for HCT for haematological diseases, solid tumours and immune disorders. Our aim is to provide guidance on HCT indications according to prevailing clinical practice in EBMT countries and centres.

Purpose: This study aims to evaluate the safety and efficacy of the CGuard dual-layer stent with its mesh embolic protection system (EPS) in elective cases for treatment of internal carotid artery stenosis and compares it to the Carotid Wallstent as benchmark.
Methods: In this retrospective, multicenter study, we analyzed data from consecutive patients who underwent carotid artery stenting with CGuard at two high-volume neurointerventional centers and compared them with prior consecutive patients treated with Carotid Wallstent (CWS), with and without a balloon guiding catheter (BGC) as protection, at the same institutions. Patient demographics, procedural details, clinical complications, early in-stent thrombosis and occlusion rates, and late follow-up restenosis rates were assessed.

Background: The escalating complexity of clinical trial protocols has considerably increased the workload for research coordinators, exacerbating staffing shortages and contributing to operational inefficiencies. These challenges are particularly pronounced at under-resourced and minority-serving research institutions, where limited capacity may hinder the implementation of trials. Early and accurate estimation of research coordinator effort is essential for effective planning, resource management, and successful clinical trial conduct.
