Method for measuring the incidence of hospital acquired infections
First Claim
1. A computer-readable non-transitory medium having computer-executable instructions stored thereon for execution by a processor to perform a method for analyzing patient hospitalization data to determine a Nosocomial Infection Marker (NIM), the method comprising the steps of:
- receiving from a database hospitalization data associated with at least one patient;
identifying from the hospitalization data a number of specimens with nonduplicate hospital isolates (SNDHI) markers through the steps of;
segregating a first isolate of a microorganism from a patient obtained during a determined first period of time;
eliminating additional isolates of the same microorganism from the patient obtained within the determined first period of time when the additional isolates were not tested against antimicrobial drugs;
eliminating each additional isolate of the same microorganism from the patient obtained within the determined first period of time when the additional isolate was tested against antimicrobial drugs and an interpreted antimicrobial susceptibility result of the test differs from the first isolate on fewer than a predetermined number of drugs;
identifying hospital isolates; and
assigning a SNDHI marker to each hospital isolate; and
determining the NIM for each patient, wherein the NIM is equal to the sum of the SNDHI markers for the patient.

Abstract
Disclosed is a method and system for analyzing patient hospitalization data to determine a Nosocomial Infection Marker (NIM), the method comprising receiving from a database hospitalization data associated with at least one patient, calculating from the hospitalization data the number of specimens with non-duplicate hospital isolates (SNDHI) markers, calculating from the hospitalization data antibiotic utilization criteria (AUC) markers, and determining the nosocomial infection marker (NIM) for each patient, based upon the calculated SNDHI and AUC markers.
