Health Care Resource Utilization for Patients With Suspected Myocardial Infarction
Abstract
Key Points Question Does implementing a 0-hour and 1-hour (hereafter referred to as 0/1-hour) high-sensitivity cardiac troponin I (hs-cTnI) protocol reduce health care resource utilization compared with a 0/3-hour standard protocol for myocardial infarction exclusion in US emergency departments (EDs)? Findings In a secondary analysis of this stepped-wedge randomized clinical trial including 32 608 patients with suspected myocardial infarction, a 0/1-hour hs-cTnI protocol reduced cardiac testing and the median length of ED stay without changing rates of ED discharge or revascularization. Meaning This study suggests that a 0/1-hour hs-cTnI protocol can reduce health care resource utilization and ED crowding without compromising safety.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 32 participants or records.
