Despite a dramatic increase in diagnostic tests and treatments over 30 years, there were no significant changes in the duration of hospitalization or in-hospital mortality for myocardial infarction.
Observational
Do increased diagnostic and therapeutic inputs over a 30-year period improve duration of hospitalization or in-hospital mortality in patients hospitalized with myocardial infarction?
A 30-year retrospective analysis demonstrated that dramatic increases in resource utilization and diagnostic testing for myocardial infarction did not translate into improvements in in-hospital mortality or length of stay.
A retrospective study over a 30-year interval measured changing patterns of inputs into the care of patients hospitalized with myocardial infarction. There was a dramatic increase in frequency of chemical laboratory tests, roentgenograms, and bacteriological examinations. These quantities had both statistically significant linear and quadratic regression components, indicating an accelerated increase over time. There has been a linear increase in electrocardiograms, sedative medication, and days of oxygen therapy. With these changes in input, there have been no significant changes in the duration of hospitalization or in-hospital mortality.
Sp et al. (Sun,) conducted a observational in myocardial infarction. Inputs into care (diagnostic tests, medications, oxygen therapy) was evaluated on Duration of hospitalization and in-hospital mortality. Despite a dramatic increase in diagnostic tests and treatments over 30 years, there were no significant changes in the duration of hospitalization or in-hospital mortality for myocardial infarction.
