percent of dead patients in "poor" condition in Hospital A: I % For both hospitals, nd the percent of patients who died and had been classied as being in "good" condition before surgery. (Use decimal notation. Give your answers to two decimal places if necessary.) For each hospital, the overall percentage of patients who died is known. For Hospital B, this percentage equals 2% whereas, for hospital A, it is equal to 3%. What conclusion(s) can you make about the death rates for these hospitals? El Patients are safer in Hospital B than in Hospital A because the percentage of patients treated in Hospital B who died is less than the percentage of patients treated in Hospital A who died. CI The condition in which a patient arrives is a lurking variable that explains why the overall death rate for Hospital A is higher than the overall death rate for Hospital B, although the death rate for Hospital A for patients in either condition is lower than the death rate for Hospital B for patients in the same condition. I:| The fact that the overall death rate for Hospital A is higher than for Hospital B, but the death rate for patients in either condition for Hospital A is lower than the death rate for patients in the same condition for Hospital B, is an example of Simpson's Paradox. El Hospital A treats a lot more patients in poor condition than Hospital B. Poor patients are more likely to die, so the death rate for Hospital A is higher overall than the death rate for Hospital B. Insurance companies and consumers are interested in the performance of hospitals. The government releases data about patient outcomes in hospitals that can be useful in making informed health care decisions. Here is a two-way table of data on the survival of patients after surgery in two hospitals broken down by patient condition. Patients are classified as being in either "poor" or "good" condition before surgery. All patients undergoing surgery in a recent time period are included. "Survived" means that the patient lived at least six weeks following surgery.
