Key result
Time of arrival to the emergency department for STEMI patients was associated with three main patterns of diurnal variation in care quality.
Why the study?
The admission time of patients with STEMI may affect care quality, prompting this evaluation of the pattern and magnitude of variation in process and outcome indicators.

Arrival time linked to diurnal STEMI care variation; leaves open whether targeted interventions reduce off-hour disparities.
Observational (n=98,628)
Yes
Does the day and time of admission affect the quality of care in patients with acute ST-segment elevation myocardial infarction?
The quality of care for STEMI exhibits significant diurnal variation, highlighting the need for targeted quality improvement to mitigate off-hour and weekend effects.
Wang et al. (2020) conducted an observational in ST-segment elevation myocardial infarction (STEMI) (n=98,628). Time of arrival to the emergency department vs. Other arrival times was evaluated on Six process indicators and one outcome indicator of STEMI care quality. Time of arrival to the emergency department for STEMI patients was associated with three main patterns of diurnal variation in care quality.
