Key result
Delaying emergency surgery lacks rigorous evidence regarding its impact on mortality and adverse outcomes, as current observational data are limited by profound selection biases.
Key points are not available for this paper at this time.
Observational data with selection bias should not guide emergency surgery timing; leaves open need for rigorous trials to assess delay effects.
Does delaying emergency surgery increase the risk of death and other adverse outcomes following that surgery? Rigorous intervention studies on time to surgery do not yet exist; available data from observational studies are limited by profound selection biases. For example, it isn’t easy to say why
