Mortality data for patients in the intensive care unit (ICU) in a health care facility, collected over
Question:
Mortality data for patients in the intensive care unit (ICU) in a health care facility, collected over 8-hour intervals, are shown in Table 8-34. Since patients have varying risks, the predicted mortality from a logistic regression model that uses the patient’s APACHE score (severity of disease) is also shown. Construct a risk-adjusted chart for the mortality proportion and comment on the ICU performance.
