Background: Percutaneous coronary intervention (PCI) outcomes can vary due to various factors, including patient clinical condition, complexity of coronary lesions, expertise of operators, and quality of the PCI center., Aims: This study evaluated the influence of PCI center volume and operator experience on patient outcomes after the procedure., Methods: Retrospective data on demographic, clinical details, and outcomes for all patients undergoing PCI across 39 hospitals in Thailand from 2018 to 2019 were retrieved. PCI center volume was categorized based on annual number of interventions: low (< 200), intermediate (200-499), and high (≥ 500). Operator experience was assessed by years of practice (low [< 5] and high [≥ 5]) and the number of PCI cases performed annually (low [< 75] and high [≥ 75]). The evaluated PCI outcomes were: PCI failure; procedural complications; PCI-related in-hospital mortality; 1 year post-intervention all-cause mortality., Results: A total of 19,701 patients who underwent PCI were included in the analysis, of whom 17,432 had follow-up data available after 1 year. Of these, 58.1% presented with either ST-elevation or non-ST elevation myocardial infarction/unstable angina, while 41.9% had stable CAD. Nearly half of the patients had triple-vessel or left-main disease, and 8.7% presented with cardiogenic shock. The percent with PCI failure, procedural complications, PCI-related in-hospital death, and 1-year all-cause mortality were 4.9%, 5.1%, 2.7%, and 11.8%, respectively. Despite patients in higher-risk profiles being treated at high-volume PCI centers and by experienced operators, there were no significant differences in PCI failure, PCI-related in-hospital mortality nor 1-year all-cause mortality compared to those treated at low or intermediate volume PCI centers. However, high-volume PCI centers had procedural complications more frequently (4.7%) than did intermediate (3.9%) and low-volume (2.5%) centers (p < 0.001). After adjusting for confounding factors, no significant associations were found between PCI center volume and PCI outcome. Similarly, no significant relationship was found between operator experience and procedural complications, nor 1-year all-cause mortality. Nevertheless, operators with more years of practice were associated with lower PCI-related in-hospital mortality (odds ratio [95% CI] of 0.75 (0.57, 0.98); p < 0.038). Additionally, operators conducting a higher number of PCIs annually tended to have less PCI failures (odds ratio [95% CI] of 0.76 (0.57, 1.01); p = 0.062)., Conclusion: A center's PCI volume did not significantly impact PCI outcome. In contrast, operator experience did impact outcomes. This result highlights areas for improvement and can help reform strategies for national PCI systems at both center and operator levels., (© 2024 The Author(s).

Background: The use of 1-year mortality following pancreatectomy for PDAC as a measure of surgical quality has not been evaluated. We aim to i) assess the 1-year mortality rate following pancreatectomy for PDAC, and ii) identify patient and hospital characteristics associated with 1-year mortality., Methods: Data was extracted retrospectively from the French national medico-administrative database. The study included patients who underwent pancreatectomy for PDAC between January 2012 and December 2019. The primary outcome was 1-year postoperative mortality. Hospitals were classified based on volume (high (≥26 resections/year) and low volume (<26))., Results: Overall, 17,183 patients who underwent pancreatectomy for PDAC were included. The overall 90-day and 1-year mortalities were 6.5 % and 21.5 %, respectively. 1-year mortality varied significantly between low and high-volume hospitals (23.6 % vs. 18.6 %, respectively, p < 0.001). Older age, Charlson Comorbidity Index (CCI), readmission, major complications were predictive factors for 1-year mortality. Pancreatectomy in low volume hospitals increased the risk of 1-year mortality by 1.23-fold (OR = 1.23, 95 % CI [1.15-1.32], p < 0.001)., Conclusion: The overall 1-year mortality after pancreatectomy for PDAC was 21.5 %, and was higher in patients of older age, with higher comorbidities, who experienced major complications, and who did not receive adjuvant therapy. Management in high-volume centers decreased mortality rates, regardless of the patient's condition., Competing Interests: Declaration of competing interest None declared., (Copyright © 2024 International Hepato-Pancreato-Biliary Association Inc.
