What is our 'duty of care'?

Clinical scenario You have just started in post with a single-handed GP. You like the work, the patient group and all the staff you work with. After a while, however, you begin to feel just a little uneasy following a number of remarks from patients: “The doctor did not listen”, “I am not sure why the doctor prescribed this” and “I’d like a second opinion”. You have also noticed in passing on a couple of occasions that repeat script requests seemed inappropriate: you felt unable to sign the prescriptions and thought medication reviews were needed. The reception staff chaperone the doctor and one of them remarks that her own doctor does breast examinations very differently: she tells you it was undertaken fully clothed. The next day a nurse speaks to you in confidence about a patient in whom she felt a diagnosis was missed. The patient is known to suffer anxiety, and was told her late period and abdominal pains were nothing to worry about. The following day she collapsed with an ectopic pregnancy. When you look at the consultation record there is only reference to her anxiety and no examination is recorded. You feel there are perhaps issues that need addressing. What will you do next?
