A qualitative analysis of the impact of healthcare personnel influenza vaccination requirements in California

Abstract

ObjectiveUsing qualitative methods, we explored the implementation of California's 2007 influenza immunization requirements of hospital-based health care personnel (HCP). MethodsWe conducted nine case studies of California hospitals with different HCP vaccination rates and policies. Case studies consisted of interviewing 13 hospital representatives and analyzing relevant hospital documents, including influenza policies. We also conducted 13 semi-structured phone interviews with key state and county public health officials, union representatives, and officials of various professional healthcare organizations. ResultsOur qualitative results suggest that California's vaccination requirements likely did not increase influenza vaccination uptake among HCP. The law was not strong enough to compel hospitals with low and medium vaccination rates to improve their vaccination efforts, and hospitals with high vaccination rates were able to comply fully with the law by continuing to do what they were already doing – namely offering vaccinations to HCP, providing education about the risks of influenza and the benefits of vaccination, and obtaining signed declinations from those who refuse vaccination. Nonetheless, we found that by publicly raising the issue of influenza vaccination in the context of public safety and healthcare quality, California's law encouraged hospitals to develop and implement data systems to monitor the effectiveness of vaccination promotion efforts and prompted discussions, and, in some cases, adoption of stricter vaccination requirements at hospital or county levels. ConclusionsOur findings generally support the literature that suggests that permissive influenza vaccination requirements, though politically feasible, provide little direct incentive for hospitals to focus efforts on increasing HCP vaccination rates.
