Question

Polymerase chain reaction (PCR) is used to determine that strain USA100 caused 80% of the MRSA cases in Dr. Dwayne Clark's hospital. Dr. Clark compares the number of patients with MRSA to the procedures performed. Based on the information in the table, which procedure increases the likelihood of infection most? Which procedure reduces the likelihood of infection most? Which health policies would you implement to reduce the number ofMRSA-infected cases in Dr. Clark's hospital? 2. Procedure Total number of patients receiving procedure 1807 16,516 5659 1 7367 MRSA-infected patients Hemodialysis Intravenous (IV) catheter Surgery Urinary bladder catheter Ventilator (invasive airway) 813 1057 945 1750 772

Explanation / Answer

From the above given data, the percentage of people getting infected with MRSA can be calculated.

Hemodialysis - 44.99%

Intravenous catheter - 6.39%

Surgery - 16.69%

Urinary bladder catheter - 22.09%

Ventilator - 9.80%

So, it is evident that Hemodialysis procedure is most likely to cause infection to the patients than any other procedure.

Intravenous catheter is least likely to cause infection to the patients.

Hospital infection control policies must be implemented to reduce the number of MRSA infections in the hospital.
