A

When we are being inconsistent. We find ourselves acting in a way that does not fit with our thoughts or values, this causes discomfort.

Q

How can we minimise medical errors?

A
  1. Be realistic -> errors happpen, strive to learn when and which errors you make, put a plan in to pick them up
  2. safety netting -> “come back in 2 days if you’re no better”
  3. Diagnosis: every diagnosis is only provisional, until new info comes along
  4. red flags: prompts tp help you act
  5. Insert thinking points into care plan, rethink cases from scratch actively look for disconfirmatory evidence to your hypotheses
  6. errors more likely when stressed/ tired -> everyone can make them
  7. Hierarchy and pressure to conform –> errors more likely if junior staff too trusting of what they are told, teams should have processes to help people speak up
  8. Teams: share work, be supervised, keep checking your work against others, reflect
