Active waiting list management: potential usefulness in a community eating disorders service.

We explored the usefulness of an initiative for managing a treatment waiting list in a community eating disorders service. We sent 108 patients awaiting treatment an opt-in letter and, if necessary, a reminder 3 weeks later. Those who opted in were compared with those who did not. Of those receiving the letter, 67.6% opted in and did not differ significantly from those who opted out on measures of eating disorder pathology and general functioning. However, they had waited less time. Opt-in letters may help to identify those who no longer want to access services, thereby allowing resources to be directed towards those who still want treatment.
