  • ICD-10 codes for the emergency-sensitive conditions are provided in parentheses.7 Shown are conditions with significant changes in both periods while the remaining diseases are summarised in online supplemental table S1.

  • *According to the Panel on Emergency-Sensitive Conditions,7 disease categories are based on primary diagnosis. We have summarised acute myocardial infarction (I21) and other acute ischaemic heart disease (I24) as well as cerebral infarction (I63) and unspecified stroke (I64) since case volume for I24 and I64 was <10.
