When answering clinical questions we give a range of answers. Some are answered very well and others less well. If the evidence is there – great, if not the answers are less complete. Already, today, we’ve answered two questions at the different end of the spectrum.

The ‘good’ answer “Can you prescribe HRT for someone with focal migraines. If not what can be tried for her flushes? Also would HRT be advisable to protect her bones?” . This uses a number of evidence sources, principally PRODIGY. This answer links a number of separate sources of good evidence to ‘weave’ a ‘good’ answer.

The ‘bad’ answer “Can raised uric acid or gout could cause tinnitus?” We only found one reference in Medline and that was from Medical Hypotheses. So as we point our in our answer – it’s a hypothesis not evidence.

On one level the latter answer is bad. It’s bad as it doesn’t resolve the uncertainty for the GP. However, it’s an appropriate answer as that is the only evidence.
