Introduction Improving mental healthcare for adolescents is a global policy priority. Despite demands for community-based services, many adolescents require more intensive interventions, such as an inpatient admission. This is typically at a point of crisis, often accompanied by intense emotional dysregulation, impairment of coping function and impulsivity. However, limited evidence exists on how best to support this group while they are in inpatient care, aside from pharmacological treatments which have a limited role in adolescents. Little is known about the models of care (MoC) offered in inpatient units, whether adolescents perceive these as helpful and the perspectives of caregivers and clinicians. Here, we describe a protocol which aims to explore and evaluate an inpatient MoC. Methods and analysis We designed a longitudinal, mixed-methods, case study. The population consists of adolescents, caregivers and clinicians at a single inpatient unit in Melbourne, Australia. Standardised outcome measures, including semi- structured interviews, will be administered to adolescents at three time-points, T1 (admission), T2 (discharge) and T3 (6 months post discharge). Caregivers will also be interviewed at T1, T2 and T3. Clinicians will be interviewed once. The measures include: Life Problems Inventory, Quick Inventory of Depressive Symptomatology, Kessler Psychological Distress Scale and the Youth Self-Report. Health of the Nation Outcome Scales for Children and Adolescents will be collected at T1 and T2. Quantitative analysis will include descriptive statistics and paired t-tests summarising adolescents admitted to the unit, clinical characteristics and longitudinal data on symptomatology. Qualitative data will be analysed using both thematic and trajectory analysis. Data collection began in May 2017 and will cease with T3 interviews by October 2018. Ethics and dissemination.
