Using peer feedback to improve handwashing and glove usage among Thai health care workers

Abstract

Background: Without protective practices such as Universal Precautions, health care workers are at substantial risk for bloodborne infection, especially in areas such as Thailand with high prevalence of HIV infection. The purpose of this study was to evaluate the effectiveness of a peer feedback program (PFP) on handwashing and glove wearing (HW/GW) among Thai health care workers.

Methods: Subjects (N = 91) were randomly assigned to receive PFP versus no treatment. By using a checklist, peer observers rated HW/GW compliance in their coworkers during patient care. For 1 month, the investigator posted a report of compliance behaviors from each 3 days of observations. HW/GW was also assessed by the investigator by direct observation at 1 month before the intervention, during the intervention period, and 1 month after the intervention.

Results: Baseline HW/GW rates for the PFP and control groups were 49.2% and 61.5%, respectively. The PFP group had a significantly higher adjusted compliance rate than the control group during the intervention period (P =.0001). However, there was no significant difference in the compliance scores obtained 1 month after the intervention.

Conclusions: The PFP was effective during the intervention period, but there was no retention of effect. Therefore, adjunct methods should be sought to promote retention of effect.
