Infection Prevention Communication Within a Health Sytem's Ambulatory Surgery Centers

Abstract

model fit, indicated by a nonsignificant chi square value, was calculated with the Hosmer and Lemeshow goodness-of-fit test. Results: In all, 3,188 HCWs completed the survey; half of which (n 1⁄4 1,719) reported no hospital work time. HCW compliance was highest for the 2010/2011 seasonal influenza vaccine (78.9%, n 1⁄4 2,514), followed by uptake of the 2009/2010 seasonal influenza vaccine (74.9%, n 1⁄4 2,383), and lowest for the H1N1 influenza vaccine (63.3%, n 1⁄4 2,017); these differences in compliance were highly statistically significant (p < .001) for all three comparisons (2010/2011 vs. H1N1, 2010/2011 vs. 2009/2010, and 2009/2010 vs. H1N1). In logistic regression stratified by hospital versus nonhospital setting, and controlling for demographics and past behavior, the determinants of 2010/2011 seasonal influenza vaccination among non-hospital-based HCWs included having a mandatory vaccination policy (odds ratio [OR], 21 [95% confidence interval {CI}, 6.7 64.4]), perceived importance (OR 7.6 [CI: 4.3 13.3]), no fear of vaccine side effects (OR 4 [CI: 2.3 7.1]), free and on-site access (OR 3.3 [CI: 1.9 5.7]), and perceived susceptibility to influenza (OR 2.4 [CI: 1.3 4.2]). Determinants of hospitalbased HCW vaccine compliance included having a mandatory vaccination policy (OR 32 [CI: 8.4 118.7]), belief that HCWs should be vaccinated every year (OR 4.3 [CI: .11 .50]), occupational health encouragement (OR 2.9 [CI: 1.3 6.7]), perceived importance of vaccination (OR 2.9 [CI: 1.1 7.6]), on-site access (OR 2.9 [CI: 1.1 7.3]), and no fear of vaccine side effects (OR 2 [CI: 1.1 3.7]). The final models correctly classified 78% of the non-hospital respondents and 68% of the hospital-based workers. Conclusions: Non-hospital-based vs. hospital HCWs' reasons for vaccine uptake differed. Targeted interventions should be aimed at workers in these settings to increase their vaccine compliance, including implementing a mandatory vaccination policy.
