I read with interest the article by Zwaan et al1 analyzing the causes of diagnostic adverse events (DAEs). They conclude that “knowledge-based mistakes” were the most common, but I believe that the real issues lie hidden behind the otherwise compelling statistics developed in the article.
We live in a setting where we increasingly see medicine practiced by protocol. That is not to say that compiling best-practice guidelines or evidence-based algorithms are bad, but what it encourages is a lack of “creative thinking” when seeing patients and more of a “cookbook approach.” Couple this with the increasing pressures to see more patients in a shorter period, to get patients out of the hospital faster, and to enforce a conformity of therapy in the name of “comparative effectiveness,” and we see DAEs because practitioners just are not encouraged to think creatively.
