MSDH conducts data validations on each type of infection monitored. The purpose of this task is to verify that the information facilities submit to CMS is accurate and represents the HAIs at the facilities. MSDH picks facilities at random and reviews medical records that the facility reported as a HAI. These validations are used solely on the premise of educating the facility in proper CMS reporting and helping the facility to provide complete and accurate data to CMS and MSDH. If MSDH finds any misclassifications of HAIs, the facilities are asked to update the National Healthcare Safety Network (NHSN) with correct data so that CMS and MSDH can accurately evaluate HAIs in the area. MSDH conducted six data validations for CLABSIs and thee validations for CAUTIs in 2015.
