ABSTRACT

BACKGROUND: Repeat departmental-wide surveys are commonly employed for infection-control. There remains debate concerning their cost-effectiveness.

AIM OF THE STUDY: To measure the impact of repeat departmental-wide surveys in major in-patient departments (IPD) and ambulatory facilities (AF) in a tertiary care hospital.

DESIGN: Retrospective study of 138 surveys conducted in 96 departments over a five-year period.

METHODS: Two itemized questionnaires were designed to assess the most frequently inadequately-adhered-to infection control measures: one for IPD (with 21 items), the other for AF (with 17 items).

RESULTS: A total of 72 surveys were conducted in 49 IPDs, of which 39 (54%) were repeat surveys, and 66 surveys in 47 AFs, of which 33 (50%) were repeat surveys. The baseline rate of adherence/department was 71%±14 for the IPD, with an increase from the first to the last survey to 82%±13 (p=0.037). In 15/21 measured infection control items, adherence improved. Adherence to infection control items was lower at baseline in the AFs than in the IPDs (63±27), with an increase to 76±20 (NS). Although adherence improved for nine items, it deteriorated in another eight, producing an overall statistically unchanged outcome.

CONCLUSION: Repeat whole-department surveys contribute moderately to increased adherence to infection control guidelines. Ambulatory facilities demonstrate lower rates of adherence to infection control guidelines and are less receptive to educational measures.
