The recent article by Chan et al1 finds wide variations in the incidence of delayed defibrillation among hospitals that are not adequately explained by hospital-level factors. The authors assume that these variations represent real differences in hospital performance and call for efforts to identify the approaches of top-performing hospitals so that other facilities may adopt them.
