As a pediatrician caring for hospitalized children, I deal with fear on a daily basis. My day is saturated with it. I encounter fear in a variety of presentations, with parental fear the most obvious but probably least impactful on my management decisions. I do spend a lot of time and mental energy calming the fears of others but more managing my own, both struggling to prevent it from biasing my thought process and harnessing it as a productive motivational force. I devote a significant amount of effort towards teaching residents and students the practice of inpatient pediatric medicine and fear can be a valuable teaching tool when used appropriately.
So I admit that I take advantage of fear to a certain extent in my practice. Most pediatricians do. Maybe we all do. Proper informed consent, for instance, must include potential poor health outcomes related to medical intervention or the refusal of them. I accept that fear is an impetus for seeking medical care. Parents should be afraid of poor health outcomes from vaccine-preventable illnesses, for example. They should be made aware of the repercussions of poor adherence to home asthma management or of not placing their child in a proper car seat every time they put them in a car. Fear can serve the greater good.
But there is a difference between these unavoidable aspects of science-based medical care and the abuse of fear by practitioners of irregular medicine.
