De Marco and colleagues claim that the standard account of invasiveness as commonly encountered ‘…does not capture all uses of the term in relation to medical interventions1 ’. This is open to challenge. Their first example is ‘non-invasive prenatal testing’. Because it involves puncturing the skin to obtain blood, De Marco et al take this as an example of how an incision or insertion is not sufficient to make an intervention invasive; here is a procedure that involves an incision, but it is regarded as non-invasive. However, this ignores the context, and the term should really be understood in reference to the fetus. It is hard to believe healthcare professionals regard taking blood to measure, for example, ferritin levels as invasive but taking blood to look for fragments of fetal DNA as not. If anyone uses the term thinking it is not invasive to the mother, the solution would be to call it invasive, not redefine what is invasive.
Is electroconvulsive therapy invasive?
De Marco and colleagues’ second example is describing electroconvulsive therapy (ECT) as invasive. However, this is not borne out by their referenced papers. The first cited source is about non-invasive brain stimulation2 and only contains a single sentence about ECT. This sentence may suggest that their view is that ECT …
