The referral rate to the Psychotherapy Department at the Warneford Hospital, Oxford, has increased by 84% in the last three years, creating a bottleneck at the assessment stage. As part of the response to this we carried out the audit reported here. Assessment for psychotherapy is costly in professional time. If any group of referrers is significantly better at referring patients who need, and make use of psychotherapy, we would have to consider selectively accepting referrals from these sources. We thus asked whether different referrer groups, and different “levels” of referral (secondary or tertiary), were more or less likely to provide patients who ultimately entered treatment.
