The overall mortality rate for patients who have had a cerebrovascular accident (CVA) is 15.8%. You have been asked to compare the hospital’s mortality rate to that of the state. Using the data provided in Table 2-A.5,

calculate: a. the observed mortality rate b. the expected mortality rate c. the standard mortality ratio (SMR) for the hospital, using the indirect method of standardization Explain the results. Hospital Discharges for CVA
