Background: University of Pittsburgh Medical Center Presbyterian Hospital (UPMC PUH) established a goal of 85% HCW flu vaccine compliance in 2010.  Initial efforts to reach this goal included increased education and convenient free vaccine clinics.  Despite these efforts, HCW vaccine coverage remained below target and HA Flu accounted for over 10% of all inpatient flu cases.  In an effort to increase HCW vaccine coverage as well as decrease HA Flu, a series of strategies were implemented each year, such as a system wide hand hygiene (HH) program and an additional flu prevention measures grid describing precautions to take in specific events like flu clusters.  In 2015-16 strategies culminated to a mandatory HCW flu vaccine program whereby HCWs demonstrated vaccine receipt by wearing hang tags or were required to perform universal masking if they had a valid medical or religious vaccine exemption.  To assess how well these strategies impacted HA Flu, the percent of HCW vaccine compliance was compared with the percent of HA Flu each year.

 

Methods:  HCW flu vaccine compliance was calculated from Employee Health records.  HA Flu was defined as a positive flu RT-PCR collected ≥ hospital day 4 with at least 2 of the following symptoms: rhinorrhea, nasal congestion, myalgia, fever, headache, sore throat, cough, and/or fatigue.

 

Results:  Previously the largest decrease in HA Flu rate occurred the same year the HH campaign was implemented (13% in 2011-12 to 3% in 2013-2014).  After that initial decrease, HA Flu rate increased each year until 2014-15. In 2015-16 the highest flu vaccine compliance (95%) was achieved with the lowest HA Flu rate. Additional analysis revealed that a large proportion of HA Flu occurred during the period between the HCW vaccine deadline (Dec 14) and the 6 weeks of susceptibility prior to effective immune response (Jan 25). 

 

 

Conclusion:   

·         HCW flu vaccine compliance ≥85% was only achieved after implementation a mandatory vaccine policy

·         The addition of the HCW mandatory vaccine program to our flu prevention bundle led to an overall decrease in the HA Flu rates

·         A portion of HA Flu cases might have been prevented had HCWs received their vaccines earlier in the season

·         Moving HCW vaccine deadline to an earlier date may further reduce HA Flu
