Collaborative care with child and adolescent mental-health services — formative SAQs

SAQ 1 (10 marks)

A general paediatrician in a metropolitan clinic is concerned that many of the anxious and low-mood adolescents she sees are referred to CAMHS and never engage, while others with clear need wait months. Her clinic is considering embedding a behavioural-health clinician and joining a statewide child psychiatry access program. [1] [2]

1. Define collaborative care and classify the four models of paediatric–CAMHS integration along the spectrum of increasing integration. (4) [1] [5]
2. Explain why the treatment gap exists and how collaborative care is designed to close it, citing the developmental epidemiology and the evidence for integrated care. (3) [3] [6]
3. Describe two concrete mechanisms by which a child psychiatry access program would help this paediatrician, beyond advising on a single child. (3) [2] [4]

Model answer — SAQ 1

(1) Definition and classification (4). Collaborative care is a structured, team-based, measurement-guided partnership between paediatric primary care and specialist CAMHS that shares accountability for a young person's mental health across a stepped continuum — not a referral and a handshake. The AACAP 2023 clinical update frames it as an embedded behavioural-health clinician, a consulting psychiatrist providing caseload oversight, a care manager, and a registry-tracked plan. The four models, loosest to tightest: (A) referral out (identify, refer, hand over; no shared record; long waits; drop-off); (B) consultation-liaison / child psychiatry access program (same-day telephone advice, warm handoff, facilitated referral); (C) co-located / parallel (behavioural-health clinician on site, direct face-to-face handoff, often separate records); (D) fully integrated collaborative care (embedded clinician in the team, measurement-based care, shared registry and single accountable plan). Access and outcomes generally improve as integration increases, but so do cost and workforce demand. [1] [5]

(2) The treatment gap and its closure (3). The gap exists because paediatric primary care is the de facto front door for youth mental health, presentations are often somatic and easy to miss, and the specialist CAMHS workforce cannot see every affected child. The developmental epidemiology is decisive: about half of all adult mental illness begins before age 15 (Kim-Cohen, Dunedin cohort), so youth is the prevention window. Collaboration closes the gap by engineering the pathway — routine screening for earlier detection, an embedded clinician for task-shifted evidence-based intervention, psychiatrist caseload consultation, measurement-based stepped care, and a shared registry so no patient is lost. The Asarnow 2015 meta-analysis found integrated medical-behavioural care improved child and adolescent behavioural-health outcomes over usual primary care. [3] [6]

(3) Access-program mechanisms (3). Two population-level mechanisms beyond one-to-one advice: (a) capability transfer — the same-day phone consultation builds the paediatrician's knowledge and confidence, so future similar presentations are managed in primary care, expanding effective workforce capacity; and (b) facilitated warm handoff — direct, supported referral with a named contact reduces the lost-referral drop-off that plagues simple referral. The Massachusetts child psychiatry access program sustained rapid response and high use through COVID-19, demonstrating that access programs are resilient capacity interventions, not single-patient consultations.

SAQ 2 (10 marks)

A 14-year-old girl presents to her paediatrician with two months of low mood, declining school attendance, and a recent superficial laceration to her forearm. She has passive thoughts that she "would be better off not here" but no plan or intent. Her mother has depression. The paediatrician's clinic has an embedded behavioural-health clinician and access to a CAMHS team and a child psychiatry access program. [1] [3]

1. Outline the immediate priorities before forming a collaborative treatment plan. (3) [1]
2. Describe the stepped collaborative management, specifying who leads at each tier and how medication would be shared. (4) [1] [3]
3. Explain how you would handle consent, confidentiality and information-sharing across the paediatrician, behavioural-health clinician, school and CAMHS. (3) [2] [5]

Model answer — SAQ 2

(1) Immediate priorities (3). First, a structured suicide and self-harm risk assessment and safety plan, because the self-laceration and passive death wishes raise the risk priority above routine collaborative management; acute risk overrides the standard pathway for same-day crisis response if intent or plan emerges. Second, exclude medical and substance mimics and assess for comorbidity (anxiety, trauma, emerging bipolar or psychosis). Third, complete a multi-informant psychosocial assessment (the young person alone under appropriate confidentiality, plus caregiver and school collateral) with an SDQ, and note the maternal depression as a family-system factor. [1]

(2) Stepped collaborative management (4). Given moderate depression with self-harm, this is Tier 3 with shared care: specialist CAMHS leads team therapy (cognitive-behavioural or interpersonal therapy) while the paediatrician and embedded behavioural-health clinician remain in the team, monitoring with the SDQ and reviewing risk at each contact. If an SSRI is indicated for moderate-to-severe depression, a typical shared medication protocol is CAMHS-initiated titration and stabilisation, then transfer to the paediatrician or GP under a shared-care agreement specifying the drug, monitoring schedule, review dates and triggers for re-referral, with the consulting psychiatrist available via the access program. The care coordinator holds the plan, the registry tracks outcome, and intensity steps up (to Tier 4/5 if risk escalates) or down (to primary-care monitoring as she recovers). [1] [3]

(3) Consent, confidentiality and information-sharing (3). Explain confidentiality and its limits to the young person and obtain developmentally appropriate consent; the duty to share to prevent serious harm overrides confidentiality in a risk situation. Obtain and document consent for inter-agency information-sharing with the behavioural-health clinician, school and CAMHS at the outset, on a need-to-know basis consistent with privacy law and safeguarding duties. Use a single shared record and agreed plan so the family receives one consistent message and the child is not lost between visits; involve the mother's own treating team for the family-system risk without breaching the young person's privacy.
