Amazing to note the difference in safety records between healthcare, where doctors don't die alongside their patients; https://twitter.com/c7rky/status/941246786315964416 … ..and aviation, where pilots may well die alongside their passengers.https://twitter.com/jbarro/status/947868718020939776 …
Can't provide you with links, or claims of expertise Ken, but based upon experience of trying to influence behaviours in a corporate environment & considering what I've learned about how healthcare operates, I'd have little doubt it plays some part.
