Calculation of HAIs
Calculation of HAIs – Monthly
Device associated Infections are calculated as per 1000 device
days
Device utilization ratio – Monthly
Calculated as device days per number of patient days
Surgical Site Infection – Monthly
Calculated as per 100 surgical procedures
Case Scenario
1. In SICU, there were 2 CLABSI cases and CL
device days were 230. Patient days were 1024.
Calculate the CLABSI rate and central line
utilization ratio.
2. In Cardiac surgery cases (n= 128)done in
month of March 2019, 2 were superficial
infections and 1 was deep infection. Calculate
the SSI.
