Prospective survey of factors affecting risk discussion during consent in a surgical specialty.

BACKGROUND

The Department of Health in the UK has developed new consent guidance but without clear recommendations on how the incidence and severity of a given risk should influence its discussion during the process of obtaining informed consent. Plastic surgery is a litigation-prone specialty that offers a paradigm for assessing attitudes to consent.

METHODS

A questionnaire was sent to all surgeons at six plastic and reconstructive surgery units within the UK. It enquired what incidence of a relatively frequent minor severity risk such as wound infection, or an extremely rare but major risk such as stroke, would merit its discussion when obtaining informed consent for elective surgery.

RESULTS

Sixty of 85 questionnaires were returned. For a minor risk, there was a consensus that an incidence threshold of 5 per cent or greater would necessitate its discussion. For a major risk, the modal threshold was 0.1 per cent, but there was a greater variability of response.

CONCLUSION

There was a wide variation of opinion as to how frequently a major risk must occur before it is likely to be conveyed to a patient during the process of consent. The findings suggest that recent change in case law has yet to disseminate fully in one surgical specialty, with the potential for the challenge that consent is not 'informed'.
