The research, published on the British Medical Journal’s website, found that the risk of death within 30 days of a planned operation increased every day of the week after Monday.
“Compared with Monday, the adjusted odds of death [taking into account case mix] for all elective surgical procedures was 44% higher, and 82% higher, if the procedures were carried out on Friday or at the weekend respectively,” according to the team, which was led by Paul Aylin, a clinical reader in epidemiology and public health at Imperial College London.

Le résultat était connu pour l’ensemble des admissions à l’hôpital le week-end. Il s’agit ici d’une étude sur les opérations programmées à l’avance afin d’éliminer les différents facteurs qui pourraient introduire un biais de sélection pour les opérations du week-end.
