Inpatient treatment for eating disorders is a scarce, expensive resource. We aimed to examine length of stay (LOS) in specialist Scottish inpatient units and to identify relationships between LOS, outcome measures and other factors.
Audit of 206 admissions (89 adolescents and 117 adults) between 2009 and 2011 to all seven inpatient units in Scotland that specialize in the treatment of eating disorders. Data was collected retrospectively from electronic database and patient case files.
Physical and psychological eating disorder symptoms improved significantly during specialist inpatient admissions. Mean LOS for adolescents was 141.4 days and for adults 113.0 days. Patients gained weight during admission and increased LOS correlated with increased weight gain. Treatment under the Mental Health Act or with nasogastric feeding increased LOS in adolescents.
Future efforts should be invested in prospective studies, including several years' post-discharge follow-up, to explore correlations with LOS and guide treatment decisions. PRACTITIONER MESSAGE: Inpatient treatment in specialist eating disorder units is associated with nutritional and psychological benefits in adults and adolescents. Treatment requiring legal detention or nasogastric feeding involves longer admission. Further research is needed to see whether benefits are lasting.
饮食失调的住院治疗是一种稀缺且昂贵的资源。我们旨在研究苏格兰专科住院病房的住院时长（LOS），并确定住院时长、预后指标及其他因素之间的关系。
对2009年至2011年间苏格兰所有七个专门治疗饮食失调的住院病房的206例入院病例（89例青少年和117例成年人）进行审计。数据通过电子数据库和患者病历进行回顾性收集。
在专科住院治疗期间，饮食失调的身体和心理症状有显著改善。青少年的平均住院时长为141.4天，成年人的平均住院时长为113.0天。患者在住院期间体重增加，住院时长的增加与体重增加相关。根据《精神健康法》进行治疗或采用鼻饲喂养会增加青少年的住院时长。
未来应投入前瞻性研究，包括出院后数年的随访，以探索与住院时长的相关性并指导治疗决策。从业者须知：专科饮食失调病房的住院治疗对成年人和青少年具有营养和心理益处。需要法律拘留或鼻饲喂养的治疗住院时间更长。需要进一步研究以确定这些益处是否持久。
