    Canadian Journal of Urology, Vol.30, No.2, pp. 11467-11472, 2023

    Abstract Introduction: Adverse events in urologic procedures are poorly studied. This study analyzes the Veterans Health Administration (VHA) Root Cause Analysis (RCA) data for patient safety adverse events during urologic procedures performed in a VHA operating room (OR).
    Materials and methods: The VHA National Center for Patient Safety RCA database was queried for fiscal years 2015-2019 using urologic terms including vasectomy, prostatectomy, nephrectomy, cystectomy, cystoscopy, lithotripsy, ureteroscopy, urethral, TURBT, etc. RCAs for events outside a VHA OR were excluded. Cases were categorized based on type of event.
    Results: Sixty-eight RCAs were identified for 319,713 urologic procedures. The most common… More >

    Ensemble Based Temporal Weighting and Pareto Ranking (ETP) Model for Effective Root Cause Analysis

    Naveen Kumar Seerangan1,*, S. Vijayaragavan Shanmugam2

    CMC-Computers, Materials & Continua, Vol.69, No.1, pp. 819-830, 2021, DOI:10.32604/cmc.2021.012135 - 04 June 2021

    Abstract Root-cause identification plays a vital role in business decision making by providing effective future directions for the organizations. Aspect extraction and sentiment extraction plays a vital role in identifying the root-causes. This paper proposes the Ensemble based temporal weighting and pareto ranking (ETP) model for Root-cause identification. Aspect extraction is performed based on rules and is followed by opinion identification using the proposed boosted ensemble model. The obtained aspects are validated and ranked using the proposed aspect weighing scheme. Pareto-rule based aspect selection is performed as the final selection mechanism and the results are presented More >
