Controlled Trial Measuring the Effect of a Feedback Intervention on Hand Hygiene Compliance in a Step-Down Unit

Objective. To evaluate hand hygiene compliance in 2 adult step-down units (SDUs). Design. A 6-month (from March to September 2007), controlled trial comparing 2 SDUs, one with a feedback intervention program (ie, the intervention unit) and one without (ie, the control unit). Setting. Two 20-bed SDUs at a tertiary care private hospital. Methods. Hand hygiene episodes were measured by electronic recording devices and periodic observational surveys. In the intervention unit, feedback was provided by the SDU nurse manager, who explained twice a week to the healthcare workers the goals and targets for the process measures. Results. A total of 117,579 hand hygiene episodes were recorded in the intervention unit, and a total of 110,718 were recorded in the control unit (P = .63). There was no significant difference in the amount of chlorhexidine used in the intervention and control units (34.0 vs 26.7 L per 1,000 patient-days; P = .36) or the amount of alcohol gel used (72.5 vs 70.7 L per 1,000 patient-days; P =...
