Evaluation of an eating disorder screening and care pathway implementation in a general mental health private inpatient setting.

Background: General mental health inpatient units hold a valuable place in the stepped system of care, and for identification and treatment of people with eating disorders (EDs) or disordered eating behaviours (DEBs). This study aimed to pragmatically evaluate an evidence-informed screening and care pathway, alongside a staff education program, implemented to improve identification and treatment access for consumers with EDs and DEBs, with co-occurring psychiatric conditions, on a general mental health ward.

Methods: A mixed methodology design was mapped to the RE-AIM implementation framework. It encompassed medical record audits across two 3-month time points pre and post implementation of the pathway, and key informant consumer and health professional interviews.

Results: Process and implementation data were compared for three-month periods pre (2019, n = 348) and post-implementation (2021, n = 284). Post-implementation, intake SCOFF screening occurred in 94.7% of admissions. People with ED/DEBs diagnoses were 35 times more likely to have a SCOFF score ≥ 2 (OR = 35.2, p < .001) with the odds of identifying previously undiagnosed DEBs 3.3 times greater (p = .002). Post-implementation, for those with an ED/DEB, dietitian referrals (p < .001) and micronutrient supplementation (p = .013) were more likely. For those with weight and height data, both absolute (-1.1 kg ± 2.2 vs. 1.3 kg ± 2.3; p < .001) and percentage weight change were significantly higher post-implementation with similarities across BMI categories. Universally, consumers and health professionals expressed that the service had "changed care for the better" encouraging therapeutic relationships, mediated by trust, that resulted in better consumer outcomes. 50 health professionals undertook tailored ED and meal support therapy education. They noted that their knowledge and confidence improved allowing value to be seen in understanding EDs and the role for care within general mental health.

Conclusions: This study demonstrated that an articulated screening and care pathway could be feasibly implemented in general mental health. The evaluation demonstrated advances in ED detection and management with noted improvements in management access, care planning, physical monitoring and weight gain outcomes. Understanding stakeholders' experiences of new care practices enabled the identification of enablers and barriers for implementation, and avenues to optimise care for consumers with EDs in the general mental health setting.
