A qualitative meta-synthesis on how autonomy promotes vaccine rejection or delay among health care providers

In spite of the overwhelming evidence that highlights the effectiveness of routine vaccination, an increasing number of people are refusing to follow recommended vaccination schedules. While the majority of research in this area has focussed on vaccine hesitancy in parents, there is little research on the factors that promote vaccine hesitancy in health care providers (HCPs). Identifying factors that promote vaccine hesitancy in HCPs is essential because it may help broaden our understanding of vaccine hesitancy in patients. Therefore, the goal of this investigation was to review 21 studies and examine how professional autonomy and risk perception may promote vaccine acceptance, rejection and delay in physicians and nurses. We found that vaccine hesitant nurses and physicians shared similar views towards vaccines; both groups believed that their decision to vaccinate was separate from their role as an HCP. This belief comprised of three themes: decisional autonomy, personal risk perception and alternatives to vaccination. Both groups believed that mandatory vaccine policies reduced their ability to decide whether vaccination was in their best interests. We argue that decisional autonomy may weaken risk perception of disease, which in turn may encourage beliefs and behaviours that reinforce a 'hero persona' that reduces appropriate preventive and hygiene measures. We employ the Health Belief Model to discuss the crucial role that risk perceptions may play in reinforcing autonomy in vaccine hesitant physician and nurses. We conclude this paper by providing a set of recommendations that aim to improve the decision-making process surrounding mandatory vaccinations for HCPs.
