A substantial proportion of anorexia nervosa patients require intensive treatments, commonly inpatient or day-patient treatment. The relative merits of these treatments for adults with anorexia nervosa are unknown. Therefore, a trial investigating the clinical effectiveness and cost-effectiveness of inpatient treatment-as-usual versus a stepped-care day-patient approach in adults with anorexia nervosa (DAISIES) was commissioned. This trial terminated prematurely due to poor recruitment, mainly resulting from COVID-19’s impact on service provision.
