Abstract
BACKGROUND: Hand hygiene compliance among healthcare workers (HCWs) in intensive care units (ICUs) is disconcertingly low. AIM: To identify the effective intervention(s) for increasing HH compliance among HCWs in adult ICUs. METHODS: Two major electronic databases, OVID Medline and CINAHL, were searched by using a combination of MeSH terms and text words (e.g. hand hygiene, hand washing, compliance, adher*, improve*, develop* and intensive care unit) for relevant articles. This was supplemented by Google Scholar and hand searching of included bibliographies. Data from identified articles were then abstracted, quality-assessed, and combined into a summary effect. FINDINGS: Of 89 titles and abstracts that were identified, 14 articles were finally included. Overall study quality was good. However, variations in design, setting, sample size, and intervention(s) tested precluded a meta-analysis; hence a narrative synthesis was conducted. The interventions included education, observation, provision of supplies, improving access and directive support; tested singly or in combination; resulted in positive outcomes in all but one study. A combination of administrative support, 'supplies', education and training, reminders, surveillance, and performance feedback raised the compliance from a baseline of 51.5% to a record 80.1%; but no set of intervention(s) could improve the compliance to the desired near-100% level. CONCLUSION: Available data suggest that multi-modal interventions are effective in raising the compliance to a 'plateau' level but not up to the desired standard. Methodologically appropriate trials of combined interventions could enhance the evidence about interventions to improve hand hygiene compliance among ICU staff.
