Question
A key hospital outcome measure of clinical performance is length of stay (LOS), that is, the number of days a patient is hospitalized. For patients at one hospital with acute myocardial infarction (heart attack), the length of stay over the past four years has consistently decreased. The hospital also has data for various treatment options such as the percentage of patients who received aspirin upon arrival and cardiac medication for Left Ventricular Systolic Dysfunction (LVSD). The data are as follows: Year 2007 2008 2009 2010 Variable Average LOS 4.29 days 4.34 days 4.27 days 4.15 days Calculate descriptive statistics for the data. Do not round intermediate calculations. Round your answers to four decimal places, when needed. Descriptive Statistics: LOS, Aspirin, LVSD LOS (days) Aspirin (%) LVSD (%) Aspirin on arrival Mean 93% 97% 99% 100% LVSD medication 90% 92% 97% 98% Standard Error Standard Deviation Minimum Median Maximum Calculate correlations for the data. Do not round intermediate calculations. Use a minus sign for negative values, if any. Round your answers to three decimal places.
