PE3.4 | Child Developmental Unit Visit — SDL Guide (Part 2)

Interpretation: What CDU Findings Mean

The value of the CDU lies not only in the assessment process but in the integrated interpretation that emerges from team deliberation. Understanding how findings are synthesised to reach a diagnosis and management plan is essential for appreciating what you have observed.

A child who scores below the 5th percentile on DASII in two or more domains, and whose neurological examination shows hypotonia and abnormal reflex persistence, will likely receive a working diagnosis of global developmental delay and a referral for neuroimaging and metabolic screening. A child with isolated language delay and normal motor and social functioning may simply be referred to speech therapy with a watchful-waiting plan and hearing assessment by BERA. A child showing poor eye contact, absent pointing, restricted interests, and stereotyped movements will be assessed further for autism spectrum disorder using CARS or ADOS.

Critically, findings at the CDU translate into three types of output:
1. Diagnostic formulation: A working diagnosis (e.g., global developmental delay secondary to HIE, or Down syndrome with associated intellectual disability) or a differential pending investigation results.
2. Therapy prescriptions: Specific therapy goals and frequency recommendations from each therapist — not generic referrals but individualised plans with measurable targets.
3. Individualized Education Plan (IEP) recommendations: Based on the special educator's and psychologist's assessment, recommendations for classroom support, learning accommodations, and school type.

The CDU report that goes back to the referring doctor and school is a multi-professional document — each discipline contributes a section — and it forms the basis for ongoing management, reassessment, and government disability certification under the RPWD Act 2016.

Applied Observation and Supervised Practice

Your role during the CDU visit is that of an active observer: you are not assessing the child independently, but you are engaging in a purposeful learning activity that requires preparation, structured observation, and reflective synthesis. The competency PE3.4 explicitly specifies observation of CDU functioning — this means attending to the process, not just the outcome.

To make the most of your visit, prepare the following structured observation tasks in advance and complete them during the visit:

Observation Task 1 — Team interactions: Identify each team member and note what tool or technique they use with the child. What did each professional focus on that the others did not?

Observation Task 2 — Parent communication: Observe how the team interacts with the parent/caregiver during the history, during assessment, and during feedback. Note what language is used, how difficult information is delivered, and how the parent responds. What would you do differently or the same?

Observation Task 3 — Child behaviour: Choose one child to observe closely. Record: Does the child make eye contact? Does the child respond to their name? Does the child show joint attention (looking where you point)? Does the child engage in functional play? These observations correspond directly to ASD and social-communication screening items.

Observation Task 4 — Diagnostic reasoning: After the team case conference, discuss with your supervisor: What were the key findings that led to the diagnosis or differential? What investigations were ordered and why? What therapy was recommended and with what goals?

After the visit, complete a structured reflection (see below). CDU observation counts toward your required supervised clinical exposure and should be documented in your portfolio with your supervisor's signature.

In many tertiary-care settings in India, CDU services operate under the paediatric outpatient department or as part of the District Early Intervention Centre (DEIC) under RBSK. If your institution does not have a dedicated CDU, the RBSK DEIC is an equivalent observation opportunity — the same multidisciplinary model applies.

Self-Assessment

Consolidate your learning from this module and your CDU observation with these application prompts. The questions below are designed to move you from passive observer to active clinical reasoner: they ask you to interpret what you saw, to reason through a diagnosis, and to articulate in plain language what you would say to a family. This kind of post-observation synthesis — converting observation into structured knowledge — is how clinical experience produces durable learning, as opposed to simply accumulating hours of watching. Take your time with each question; there is no single correct answer for the communication prompts, and the quality of your reasoning matters more than arriving at a specific label.

Reflection Question 1: You observed a 4-year-old child in the CDU who presented with delayed speech, poor eye contact, and repetitive hand movements. The clinical psychologist administered the CARS and scored the child at 35 (moderate autism range). The speech therapist noted absent joint attention and no functional pointing. The physiotherapist found normal tone and gross motor function.
- What diagnosis would the team most likely reach?
- What therapy recommendations would you anticipate?
- How would you explain this diagnosis to the parents using plain, respectful language?

Reflection Question 2: A colleague asks: 'Why do we need a whole team for developmental assessment? Couldn't the paediatrician just do it all?' Using what you observed in the CDU, write a 3-sentence answer.

Short-Answer: List the six steps in the CDU visit workflow and for each, name one key piece of information obtained at that step.
