Health care workers’ participation in influenza vaccination programs.Application of the PRECEDE- PROCEED model

Influenza vaccination of Health Care Workers (HCWs) is recommended by several health authorities worldwide aiming to prevent influenza, to reduce staff absenteeism due to illness and to protect vulnerable patient populations from the increased morbidity and mortality that influenza carries. However, despite recommendations and proven efficacy and cost effectiveness of influenza vaccine, vaccination rates are persistently low globally. Aim:The aim of this study was to identify the factors that influence HCW’s decision to participate in flu vaccination, to classify them according to the PRECEDE-PROCEED model of health promotion planning and to summarize the characteristics of health promotion interventions that have proved helpful in increasing influenza vaccination rates among health care workers. Methods: A literature review was performed in MEDLINE and SCOPUS databases during the last decade.
