• At the regional level, analysis of emergency department visits for the iCanicule composite health
  indicator during the heat wave shows:
  • low daily numbers of emergency department visits during the episode and a situation comparable to that observed during the reference period (August 18–27), for all age groups as well as for those aged 75 and older;
  • a stable number of hospitalizations following a heat-related
    visit to the emergency department over the same time period;
  • no medical procedures recorded for this indicator at the SOS Médecins association in Ajaccio.
