Collaborative care with child and adolescent mental-health services — branching viva

Opening

Examiner: What do you understand by collaborative care between paediatrics and child and adolescent mental-health services? [1]

Candidate: 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. It is 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 reason it exists is that paediatric primary care is the de facto front door for youth mental health, and most affected children are either unrecognised or lost between services. [1] [2]

Branch A — Classification

Examiner: Classify the models of collaboration you might use. [1]

Candidate: Four models along a spectrum of increasing integration. Referral out — identify, refer, hand over, no shared record, long waits, drop-off. Consultation-liaison, or a child psychiatry access program — same-day telephone advice, warm handoff and facilitated referral, exemplified by MCPAP and Project TEACH. Co-located or parallel — a behavioural-health clinician on site with direct face-to-face handoff but often separate records. Fully integrated collaborative care — an embedded clinician in the team, measurement-based care, a shared registry and a single accountable plan. Access and outcomes generally improve as integration increases, though so do cost and workforce demand. [1] [2]

Probe: Which would you choose for a primary-care clinic with frequent lost referrals? [4]

Candidate: A consultation-liaison access program as the entry point — it gives rapid psychiatric advice and a facilitated warm handoff that directly attacks the lost-referral problem — moving toward co-located or fully integrated care as resources allow, because the embedded clinician and shared registry are what finally stop patients being lost. [4]

Branch B — The gap and the evidence

Examiner: Why does the treatment gap exist, and what is the evidence that collaboration helps? [3]

Candidate: The gap exists because presentations are often somatic and missed, specialist CAMHS is too small to see everyone, and fragmentation loses patients. The developmental case is strong: about half of all adult mental illness begins before age 15 — Kim-Cohen's Dunedin cohort — so youth is the prevention window. The Asarnow 2015 meta-analysis found integrated medical-behavioural care improved child and adolescent behavioural-health outcomes over usual primary care, and the Massachusetts child psychiatry access program sustained rapid response and high use through COVID-19. [3] [5]

Probe: Name the mechanism by which an access program helps beyond one child. [4]

Candidate: Capability transfer — the consultation builds the referring paediatrician's knowledge and confidence, so future similar presentations are managed in primary care. That makes access programs population-level workforce interventions, not single-patient advice. [4]

Branch C — Assessment and shared management

Examiner: Take me through the shared assessment and the stepped plan for a 14-year-old with two months of low mood, declining attendance, a superficial laceration, and passive death wishes. [1]

Candidate: Immediate priority is a structured suicide and self-harm risk assessment and safety plan — the self-harm and passive death wishes raise risk above routine management. Then a multi-informant psychosocial assessment: the young person alone under appropriate confidentiality, caregiver and school collateral, an SDQ, exclusion of medical and substance mimics, and a note of maternal depression as a family-system factor. This is Tier 3 shared care: specialist CAMHS leads team therapy while the paediatrician and embedded behavioural-health clinician stay in the team, monitoring with the SDQ. If an SSRI is indicated, a shared protocol — CAMHS-initiated titration and stabilisation, then transfer to the paediatrician or GP with specified drug, monitoring, review dates and re-referral triggers. A named care coordinator holds the plan and a registry tracks outcome. [1] [3]

Probe: How do you handle consent and information-sharing across all those agencies? [2]

Candidate: Explain confidentiality and its limits to the young person and obtain developmentally appropriate consent; the duty to share to prevent serious harm overrides confidentiality when risk is present. Document consent for inter-agency information-sharing with the behavioural-health clinician, school and CAMHS on a need-to-know basis, and use a single shared record and agreed plan so the family hears one consistent message. [2]

Branch D — Stumpers

Examiner: A rural Indigenous adolescent with emerging anxiety and school disengagement — how does your collaborative model adapt? [2]

Candidate: Cultural safety, a community-based and family-inclusive model, and explicit attention to intergenerational trauma are the standard, not an add-on. For distance, telehealth closes the access gap — telemental health is acceptable and effective when adapted to developmental level. I would use an interpreter or cultural consultant if needed, engage the school, and name a local coordinator who holds the thread, rather than imposing an urban clinic model. [2]

Examiner: What overrides the routine collaborative pathway? [1]

Candidate: Acute suicide risk with intent or plan, acute psychosis or mania, a medically unstable eating disorder, or a safeguarding disclosure. These need same-day crisis response — a CAMHS crisis team, emergency department, or child-protection pathway — with a warm handoff and documented safety plan, and mandatory reporting where maltreatment is disclosed. [1]

Close

Examiner: One-line take-home. [1]

Candidate: Collaborative care shares stepped accountability for a young person's mental health across primary care and CAMHS; choose the model that matches your resources, screen with the SDQ, keep one coordinator and a shared record so no child is lost — and let acute risk override everything for a same-day response.
