In Reply As Dr Fedeli and colleagues state, the effect of any organizational characteristics, such as the day of the week for admissions, will be influenced by other factors, such as the type of hospital, and may vary by the diagnosis and reason for admission. They cite some examples of the latter. The importance of the influence of organizational context that Fedeli and colleagues raise is well illustrated by the systematic review of off-hour presentation and deaths among patients with ST-elevation myocardial infarction,1 which reported on the considerable heterogeneity of findings between different studies.
