PEDIATRICIANS' ATTITUDES, PERCEPTIONS, AND BEHAVIORS REGARDING DISCHARGING CHILDREN ON THE BASIS OF PARENTAL VACCINE REFUSAL IN THE STATE OF GEORGIA Público

Abstract

One of the greatest public health achievements of the 20th century is the significant decrease in vaccine preventable diseases as a result of vaccine development and mass immunization programs. In the United States, school vaccination requirements have had a dramatic impact in reducing disease morbidity and mortality. However, concerns regarding vaccine preventable diseases have shifted to worries about vaccine safety. Today, many parents worry that vaccines may cause more harm than the very diseases they are intended to prevent. Consequently, parents may be hesitant or refuse to immunize their children. Requests for nonmedical exemptions from vaccination requirements are becoming increasingly common. Research suggests that areas with high concentrations of nonmedical exemptions may be associated with recent outbreaks of vaccine preventable diseases, and as such, pose risks to public health. In an effort to minimize the risk to unvaccinated individuals, some physicians resort to discharging patients who, for nonmedical reasons, refuse vaccination.

In order to understand how public health professionals can address parental vaccination refusal and provide evidence to support physicians in maintaining supportive relationships with parents who express concerns regarding vaccines, a quantitative survey of primary care pediatricians in the state of Georgia was conducted. The goals of this research were to 1) estimate the proportion of primary care pediatricians within the state of Georgia who report discharging patients for vaccine refusal, and 2) understand the characteristics, behaviors, and attitudes regarding parental vaccine refusal of primary care pediatricians within the state of Georgia.

Approximately 46% of responding pediatricians reported they would support discharging a patient over complete vaccine refusal. More than half of responding pediatricians have personally discharged patients because of refusal to immunize. The primary reason for refusal is perceived to be due to concern over vaccine safety. A majority of respondents would willingly agree to an alternative vaccination schedule if a parent requested it. Findings generated from this research and its potential implications provide a foundation for areas of further research, and suggest a need for evaluation of existing practices and policies related to childhood vaccination refusals.
