Nurses spend more time with patients than most other types of providers and have unique insight into patient care and the the healthcare system.

I don’t like daylight saving time (DST). Twice a year, when we begin and end this transition, I’m tired and cranky for a week. These sudden leaps forward and backward in time disrupt our bodies’ natural relationship to what should be gradual changes of season.
Not surprisingly, some studies suggest that these assaults on our circadian rhythms may affect our cardiovascular health. Swedish studies (here and here) based on national myocardial infarction (MI) data found small but significant increases in MI rates in the first few days to a week after the change to DST.
A Michigan study of more than 42,000 MI patients treated with angioplasty found a significant increase in MIs on the Monday after the start of DST. Their data, however, indicated that the overall incidence rate of MIs in need of angioplasty did not change, and the researchers suggested that DST may simply “accelerate” the incidence of cardiovascular events in at-risk patients, pulling them forward in time.
Researchers in Finland recently reported an increase in strokes at the start of DST, and like the Michigan researchers, concluded from their […]
