Short-term Deaths After Percutaneous Coronary Intervention Discharge: Prevalence, Risk Factors, and Hospital Risk-Adjusted Mortality

New York Risk Model and Simplified Risk Score for In-Hospital/30-Day Mortality for Percutaneous Coronary Intervention

Risk models and risk scores derived from those models require periodic updating to account for changes in procedural performance, patient mix, and new risk factors added to existing systems. No risk model or risk score exists for predicting in-hospital/30-day mortality for percutaneous coronary interventions (PCIs) using contemporary data. This study develops an updated risk model and simplified risk score for in-hospital/30-day mortality following PCI. To accomplish this, New York's Percutaneous Coronary Intervention Reporting System was used to develop a logistic regression model and a simplified risk score model for predicting in-hospital/30-day mortality and to validate both models based on New York data from the previous year. A total of 54,770 PCI patients from 2019 were used to develop the models. Twelve different risk factors and 27 risk factor categories were used in the models. Both models displayed excellent discrimination for the development and validation samples (range from 0.894 to 0.896) and acceptable calibration, but the full logistic model had superior calibration, particularly among higher-risk patients. In conclusion, both the PCI risk model and its simplified risk score model provide excellent discrimination and although the full risk model requires the use of a hand-held device for estimating individual patient risk, it provides somewhat better calibration, especially among higher-risk patients.

Factors Associated with Increased Length of Stay in Post Primary Percutaneous Coronary Intervention Patients: A Scoping Review

Several studies identify factors affecting increased length of stay (LOS) in patients with post-primary percutaneous coronary intervention (PCI). However, there has not been a review study that synthesizes these results. This study aimed to describe the duration of LOS and factors associated with increased LOS among patients with STEMI after PPCI. This study used scoping review using EBSCO-host Academic Search Complete, PubMed, Scopus, Taylor & Francis, and Google Scholar databases. The keywords used in English were "adults OR middle-aged" AND "length of stay OR hospital stay" AND "primary percutaneous coronary intervention OR PPCI" AND "myocardial infarction OR coronary infarction OR cardiovascular disease". The inclusion criteria for articles were: the article was a full-text in English; the sample was STEMI patients who had undergone a PPCI procedure; and the article discussed the LOS. We found 13 articles discussing the duration and factors affecting LOS in patients post-PPCI. The duration of LOS was the fastest 48 hours, and the longest of LOS was 10.2 days. Factors influencing LOS are categorized into three predictors: low, moderate, and high. Post-procedure complications after PPCI was the most influential factors in increasing the LOS duration. Professional health workers, especially nurses, can identify various factors that can be modified to prevent complications and worsen disease prognosis to increase LOS efficiency.
