  • Background:
    Vaccinating health care workers (HCW) is recommended to prevent nosocomial transmission of seasonal influenza[1]. Mandatory vaccination policies for HCW have been employed to decrease transmission, although supporting data are limited.[2] In addition to decreased HCW-to-patient transmission, benefits cited for mandatory influenza vaccination policies include decreased HCW absenteeism. In 2013, Los Angeles County mandated all HCW either vaccinate or wear a mask for flu season[3] resulting in a significant increase in HCW vaccination at our institution. We assessed the impact this had on absenteeism among nurses.

    Methods:

    Vaccination rates were collected from nurses who received a vaccine from the health system for 2012/13 and 2013/14 influenza seasons in 22 inpatient nursing units. Absenteeism data was collected in hours worked per unit for day, evening, night shift, and corresponding sick hours each week. Float and administrative nurses and units with incomplete data were excluded.  

    Results:

    Percentage sick and vaccination status were normally distributed.  Vaccination increased significantly from 2012-2013 to 2013-2014 with a χ-squared=247.2951, df=1, p-value<0.05. Using Pearson's Chi-squared test with Yates' continuity correction, we found sick hours (absenteeism) did not change significantly from 2012-2013 to 2013-2014, χ-squared=0.1476, df = 1, p-value=0.70. After correcting for the size of the unit, there was no significant relationship between percentage sick and percentage vaccinated.

    Conclusion:

    The benefits of HCW influenza vaccination include decreased transmission to patients. We found that increased vaccination did not have a statistically significant difference on nurse absenteeism.
