Analyzing Hospital Discharge Data. David Madigan Rutgers University. Comparing Outcomes Across Providers. Florence Nightingale wrote in 1863:.
“In attempting to arrive at the truth, I have applied everywhere for information, but in scarcely an instance have I been able to obtain hospital records fit for any purposes of comparison…I am fain to sum up with an urgent appeal for adopting some uniform system of publishing the statistical records of hospitals.”
n=463; suppose actual number of deaths=40
p-value < 0.05
SMR = 24/18 = 1.33; p-value = 0.07
SMR = 66/42 = 1.57; p-value = 0.0002
