Surveillance: retrospective versus prospective.

S Blake, E Cheatle, B Mack

    American Journal of Infection Control
    |July 10, 1980
    PubMed
    Summary

    Medical record technicians accurately identified more nosocomial infections retrospectively than infection control nurses did prospectively. This finding supports using medical records for reliable nosocomial infection surveillance trends.

    Area of Science:

    • Healthcare Management
    • Infection Control
    • Medical Records Management

    Background:

    • Nosocomial infections require accurate surveillance for effective control.
    • Prospective chart review by infection control teams is a standard surveillance method.
    • The accuracy and efficiency of retrospective chart review by medical record technicians remain areas for investigation.

    Purpose of the Study:

    • To compare the accuracy of retrospective chart review by medical record technicians with prospective chart review by an infection control team for identifying nosocomial infections.
    • To determine if retrospective review can serve as a reliable method for basic nosocomial infection trend analysis.

    Main Methods:

    • A comparative study was conducted on two nursing units over a 4-month period.
    • Retrospective chart reviews were performed by medical record technicians using established criteria.
    • Prospective surveillance was conducted concurrently by an infection control nurse and assistant using identical criteria.

    Main Results:

    • The Medical Records Department, performing retrospective review, identified a greater number of nosocomial infections compared to the infection control team's prospective surveillance.
    • Data indicated that retrospective review by medical record technicians yielded a higher detection rate for nosocomial infections.

    Conclusions:

    • Retrospective chart review by medical record technicians is a reliable method for identifying nosocomial infections and establishing basic surveillance trends.
    • This approach allows infection control nurses to allocate more time to specialized investigations, research, and staff education, optimizing resource allocation.
