A pilot study to explore the impact of just-in-time patient hand hygiene education and alcohol-based handrub use on hand contamination in outpatient settings.

BACKGROUND

Patients' hands can serve as reservoirs for health care-associated and transient pathogens, both of which can contribute to illness and transmission. Most hand hygiene programs target health care workers, even though transient bacteria on patients' hands are removable with proper technique. While inpatient initiatives such as the Patients' 4 Moments for Hand Hygiene have reduced contamination, little is known about outpatient settings or the effect of just-in-time education.

METHODS

We conducted a prospective before-after pilot study of 61 outpatients at a Veterans Affairs medical center. Each participant provided bilateral hand cultures before and after alcohol-based handrub (ABHR) use, accompanied by just-in-time education based on the Visitors' 4 Moments framework.

RESULTS

Before ABHR, 52 of 61 patients (85.2%) had bacterial growth, commonly nonenteric gram-negative rods (27.9%), Enterococcus species (23.0%), and Staphylococcus aureus (16.4%). Health care-associated pathogens included methicillin-resistant S aureus (3.3%) and carbapenem-resistant Enterobacteriaceae (6.6%). After ABHR, 67.2% had no detectable growth (P < .001). Residual growth reflected low-density transient flora.

CONCLUSIONS

Outpatients frequently carry transient and health care-associated bacteria capable of causing infection but largely removable with effective ABHR use. A brief, just-in-time education intervention significantly reduced hand contamination, supporting patient-centered hand hygiene as a feasible, low-cost strategy to interrupt transmission in ambulatory care settings.
