Current perspectives on location of monitoring and length of stay following PPCI for ST elevation myocardial infarction

Abstract

Importance: There is marked variability in location of care and hospital length of stay after primary percutaneous coronary intervention for ST elevation myocardial infarction (STEMI). Observations: We performed a literature review on non-critical care monitoring and early discharge following primary percutaneous coronary intervention and describe a framework for implementation in the real world. The medical literature was searched from 1 January 1988 to 31 April 2019 using PubMed and Cochrane Central Register of Controlled Trials. Randomized clinical trials, observational studies and guideline statements were included. Available data suggest that carefully selected low-risk STEMI patients identified using Zwolle or CADILLAC risk stratification scores after primary percutaneous coronary intervention may be considered for discharge after 48 hours of hospital care. There was no increase in major adverse cardiac events, medication non-compliance or hospital readmission with this treatment strategy. There are limited data on non-critical monitoring of uncomplicated STEMI patients; however, given the low adverse events rate, this strategy is likely to be safe in selected patients and may facilitate reduced length of stay and reduce resource utilization. Conclusions and relevance: Available evidence supports the safety of early discharge after 48 hours of care and omission of critical care monitoring in carefully selected patients following primary percutaneous coronary intervention. Early risk stratification and structured discharge planning are imperative. Adoption of this treatment strategy could reduce hospital costs, resource utilization and enhance patient satisfaction without affecting outcomes.
