THUNDERSTORM ASTHMA

iPhoneIcon_BigI always thought ‘thunderstorm asthma’, localised epidemics of asthma associated with thunderstorms, was semi-factoid.  Not so.  Apparently, thunderstorms do cause asthma spikes in asthma ED attendance. This is elegantly shown in a recent Emerg Med J.

The authors, Elliot et al., looked at EDSSS data from a night when a a thunderstorm hit the West Midlands in the UK. The Emergency Department Syndromes Surveillance System (EDSSS) registers ED attendance data from a number of UK EDs in near real-time. It can be used to  detect and track anything from influenza outbreaks to nuclear fallout. (It was developed for monitoring in case of a major incident during the London 2012 olympics.)

Below is the data for asthma/wheeze/difficulty breathing subgroup. As you can see, there is a massive spike on 23/7, the night the thunderstorm hit.

    one thunderstorm in one month of monitoring? this is almost a case report.

    there are many potential confounders here, so im not sure id throw my hat in with the ex-semi-factoid group yet based on this one paper.
