You also decide to conduct a cohort study including all patients that had been treated at the hospitals at the time, comparing those with caught SARS at the hospital from other patients, to the patients who did not catch SARS. *Note that the population "at risk" does not include patients who had SARS before checking into these hospitals. You determine that 600 patients were being treated at these hospitals. Of these, there were 178 SARS cases, 36 of which went to the hospital because they had SARS. Of the remaining SARS cases who had been originally hospitalized for other reasons, 89 had stayed in rooms without an exhaust fan. These patients had been hospitalized for a total of 345 person- days before being diagnosed with SARS. There were 53 SARS patients who had been staying in rooms with an exhaust fan; these patients had been hospitalized for a total of 827 person-days prior to their SARS diagnosis.
Question 8 1 pts What is the rate of SARS in patients who had no exhaust fan in their rooms, per 1000 person-days? Enter the numerical answer to one decimal point. per 1000 person-days Question 9 1 pts What is the rate of SARS in patients who had an exhaust fan in their rooms, per 1000 person-days? Write the numerical answer to one decimal point. per 1000 person-days
Question 10 1 pts What is the rate ratio of SARS for patients without an exhaust fan in their rooms? Write your answer to 2 decimal points. Question 11 1 pts Write a sentence interpreting your result. 12pt v Paragraph | BI
D Question 12 1 pts What is the risk difference between the risk of catching SARS in the exposed group (with exhaust fan) and the unexposed group (no exhaust fan)? Calculate the answer per 1000 person-days, and write the numerical answer to 1 decimal point. per 1000 person days
