  • *All cause mortality within 90 days of an outpatient index visit with a diagnosis at risk for one of 3 diagnostic error sensitive conditions.

  • †Emergency department visit for one of the 13 diagnostic error sensitive conditions within 90 days of an outpatient index visit with a visit at risk for that condition.

  • ‡Hospitalisations were for non-elective hospitalisations either initiated through the ED or a trauma centre with a discharge diagnosis for one of 13 diagnostic error sensitive conditions within 90 days of the index visit with a diagnosis at risk for that condition.
