Factors associated with hepatitis B vaccine acceptance among nursing home workers.
School of Hygiene and Public Health, Johns Hopkins University, Baltimore, Maryland 1997 Aug; :1-222
An investigation was performed to understand the determinants of vaccine acceptance among nursing home workers, using a modified version of Weistein's Precaution Adoption Model. The secondary goal was to classify the workers according to the stages of the model and identify factors associated with each stage of the vaccine acceptance process. The sample population included 789 nursing home assistants from 21 nursing homes in the Baltimore, Maryland area. These were individuals at risk for hepatitis B (HB) virus infection. Of the 646 workers who were offered the vaccine, only 53.6% had completed the vaccine series, and 32.5% were never vaccinated. Of the 394 workers employed prior to 1992 when the OSHA standard came into effect, only 10% were vaccinated. The most important predictor of vaccination in the dichotomous model was the report that working with patients influenced the decision of the health care worker. These workers who were influenced by working with patients were more likely to have been vaccinated than those who reported no influence due to working with patients. Two other factors were a low level of fear about getting ill from the vaccine, and having attended an in service session over a year ago. Of the 14 conceptual variable groups, seven showed significant improvement in fit for the polytomous model. These were exposure, HB information, susceptibility, worry, information evaluation, vaccine benefits, and knowledge.
