INQUIRY INTO THE USE OF QUALITY TOOLS FOR ROOT CAUSE ANALYSIS [PDF]

open access: yesProceedings on Engineering Sciences
There are many possible quality tools available for RCA and this research seeks to identify which quality tools are used by quality professionals specifically when performing an RCA. An anonymous survey was emailed to an organization’s quality leaders at

Forecasting properties of the RCA models family [PDF]

open access: yes, 2009
This paper proposes to use the following models: RCA, RCA-MA, RCA-GARCH, Sign RCA, Sign RCA-MA and Sign RCA-GARCH to obtain forecasts of conditional mean of returns. For comparison, the forecasts of conditional mean from ARMA-GARCH models were calculated,

Comparison of Immediate Versus Staged Complete Revascularization in Patients With Index PCI Coronary Complications: A Study on Clinical Outcomes and Predictors of Complications

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In patients with acute coronary syndrome (ACS) and multivessel disease (MVD), complete revascularization (CR) improves clinical outcomes compared with culprit‐only percutaneous coronary intervention (PCI). However, the optimal timing of CR, immediate (ICR) versus staged (SCR), remains debated.

Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.

Buddy Wire–Augmented Intravascular Lithotripsy in Refractory Calcified Coronary Lesions: A Five‐Case Series

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Heavily calcified coronary lesions remain a major challenge in percutaneous coronary intervention (PCI), often limiting the effectiveness of intravascular lithotripsy (IVL). We report a five‐case series in which IVL failed to achieve adequate lesion modification but was successfully augmented by the addition of one or more buddy wires.

Clinical Outcomes of Drug‐Eluting Stents and Drug‐Coated Balloons in Tortuous Small Coronary Lesions

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In small, tortuous coronary lesions, the long‐term comparative performance of drug‐coated balloon (DCB) angioplasty versus drug‐eluting stent (DES) treatment remains uncertain, despite both strategies being widely used in contemporary percutaneous coronary intervention (PCI) practice. Aims This study aimed to compare 3‐year clinical

Medical adverse events: Root cause analysis of 16 reports from a teaching hospital

open access: yesPayesh, 2016
Objective: One of the most important concerns in health care systems is the patient safety. The root cause analysis (RCA) is a systematic process for identifying root causes and contributing factors of problems or events.  The objective of this study was
