Background:   Hand hygiene (HH) is a primary measure to prevent spread of acute respiratory infections (ARI); however, performance frequency among healthcare personnel (HCP) is often less than optimal.  During the ARI season, HCP education focuses on enhanced need for HH and respiratory protection. A mild (2011-12) and moderately severe (2012-13) ARI season are compared to observe if increased ARI incidence results in greater HH performance in outpatient clinics with high exposure to ARI.

Methods:   To determine if study week, season, or ARI incidence drives compliance, HH observers collected compliance from HCPs participating in the Respiratory Protection Effectiveness Clinical Trial during the 2011-12 (YR1) and 2012-13 (YR2) respiratory seasons.  Within 3 geographically diverse medical centers (CO, MD, NY), WHO's 5 Moments HH compliance data was collected over 12 weeks each season.  Regional CDC influenza surveillance data (Regions 2, 3, & 8) determined season severity.  Linear regression determined the association of HH compliance in each site with study week, season, and regional weekly influenza incidence.

Results: A total of 3,276 HH observations were collected from 10,056 HCPs. Mean HH compliance rates did not differ significantly (p=0.07) between years at 30% (YR1) and 36% (YR2).  In both years, the highest HH compliance averaged across all sites occurred at the start of the study, coinciding with the onset of influenza season (38% and 54%, respectively). Figure 1 shows influenza isolates and HH compliance measures for CO (Region 8).  HH compliance was statistically significantly associated with week in CO (reduction of 2.6% per week 95% CI 3.8%, 1.4%) but not in other sites.  Regional influenza isolates and year were not associated with HH compliance in any of the three sites.

Figure 1.

Conclusion:   HH did not improve during the moderately severe influenza season (YR2).  HH compliance declined in one site with each progressive week in both years.  Increased ARI activity does not appear to motivate HH compliance. Other educational measures should be used to motivate HH compliance and novel strategies tested to increase HH compliance during ARI season.
