Multidisciplinary Quality Improvement Intervention to Achieve Sustained Improvement in Hand Hygiene Reliability in a...

Suboptimal hand hygiene (HH) remains a significant modifiable cause of healthcare-associated infections in the intensive care unit. We report a single-center, quality improvement project aimed at improving adherence to optimal HH among physicians, nurse practitioners, and nursing staff, and to sustain any improvement over time.

A key driver diagram was developed to identify 5 primary drivers of change: leadership support, education initiatives, patient-family engagement, increased audit frequency, and individual feedback to promote accountability. We examined HH compliance over 3 years in 3 phases (pre-intervention, intervention, and post-intervention). The intervention period involved a multimodal approach designed to influence unit culture as well as individual HH practice. HH screens were installed outside the patient rooms to provide just-in-time reminders and display of regularly updated HH adherence data for provider groups.

We recorded 6,563 HH opportunities, providers included nurses (66%), attendings (12%), fellow/resident (16%), and nurse practitioners (NP) (6%). All clinical groups demonstrated HH compliance >90% during the post-intervention period. The improvements in practice were sustained for a year after the intervention.

Our report highlights modifiable factors that impact HH and may inform quality improvement interventions aimed at improving HH compliance at other centers.
