The OT Process: The Occupational Therapy Process in Pediatrics

Fundamentals of the Occupational Therapy Process in Pediatrics

• The occupational therapy (OT) process in pediatrics follows a specific, foundational sequence that must be strictly adhered to.

• Understanding this order is critical for both clinical practice and exam preparation, as questions often test clinical reasoning based on the current stage of the process.

• Stages of the OT process must never go out of order. Each stage contains specific tasks and professional responsibilities that do not apply to other stages.

• Keywords within exam scenarios (e.g., "evaluating," "discharge planning," "screening") are essential for narrowing down appropriate versus inappropriate interventions or actions.

The Seven Sequential Steps of the OT Process

• The process follows this specific order:

  1. Referral

  2. Screen

  3. Evaluation (Eval)

  4. Goal Setting

  5. Intervention

  6. Reevaluation

  7. Discharge

• Professional Roles during the Process:

  • Referral: Practitioners must know the reason for referral before treating the child. If the referral is unclear, the OT must seek clarification from the referring source. Certified Occupational Therapy Assistants (COTAs/OTAs) can send referrals to the supervising Occupational Therapist Registered (OTR) and are responsible for educating referral sources on the scope of OT practice.

  • Screening: A brief ($20$ to $30\text{ minutes}$) process to determine if a comprehensive evaluation is necessary. The result is a simple "yes" or "no" regarding the need for further testing. COTAs can perform screenings, but it is their responsibility to refer back to the OTR if an evaluation is indicated.

  • Evaluation: The OTR selects the appropriate tools. Entry-level OTAs can assist under supervision. Intermediate or advanced OTAs who have established service competency may administer standardized assessments, though the OTR remains responsible for the selection and interpretation.

  • Intervention: The OTR develops the plan based on the evaluation and goals. COTAs collaborate by sharing knowledge about the client. COTAs can carry out the implementation but must report significant client changes or issues to the OTR.

  • Reevaluation and Discharge: The OTR determines when a reevaluation is indicated or when it is time to discontinue services. The COTA contributes progress reports and suggests future needs or discharge readiness.

Comprehensive Evaluation: Approach and Frameworks

• Occupational Profile: Every evaluation begins here. It captures documentation on the child's development, strengths, weaknesses, performance contexts, and family priorities.

• Top-Down Approach:

  • Focuses on participation in functional tasks and occupations (e.g., play, dressing, feeding, school-based tasks).

  • Observation occurs while the client is engaged in the actual occupation.

  • This is the primary approach favored by OTs.

• Bottom-Up Approach:

  • Focuses on underlying deficits or component skills that hinder performance (e.g., range of motion, fine motor skills, sensory processing, attention).

  • This approach is "deficit-based."

• Metaphorical Pyramid: Imagine a pyramid where occupation is the single block at the top, supported by multiple blocks at the bottom (sensory, motor, psychosocial skills).

  • Top-Down: Looking at the top block first.

  • Bottom-Up: Looking at the support blocks first to see if they can support the top.

• Evaluation Mnemonic (Professor Perfectly Observes All):

  • Profile

  • Performance (measured via Observation and Assessments).

  • In pediatrics, a key "footnote" to this is the Interview (of parents or teachers), leading to the specific pediatric mnemonic: Interviewing a Professor who Perfectly Observes All.

Standardized and Non-Standardized Assessments

• Standardized Assessments:

  • Require strict adherence to the user manual and test protocols.

  • Deviations from the protocol (e.g., if a child cannot follow instructions) must be documented, and the assessment may no longer be considered standardized.

  • Norm-Referenced: Compares a client's performance to the average of their peers (e.g., Sensory Profile). Performance is rated relative to others (much more/less than others).

  • Criterion-Referenced: Compares the client to a specific checklist of skills or tasks rather than peers. An example is the Hawaii Early Learning Profile (HELP), which uses age-range checklists for language, cognitive, and motor skills.

• Non-Standardized Assessments:

  • No specific protocol or mandatory wording.

  • Highly customizable to the child's needs (e.g., adjusted wording, rating scales, questionnaires).

• Clinical Judgment: Standardized results should never be used in isolation. They must be combined with clinical judgment, structured/unstructured observations, caregiver concerns, and referral information.

Mathematical Concepts in OT: Standard Deviation and Percentile Rank

• Standard Deviation (SD):

  • Measured against the mean ($\mu$) on a bell curve.

  • The mean ($\mu = 100$) represents average performance.

  • $-1.0$ to $-1.5\text{ SD}$: Minimal delay; services are generally not warranted.

  • $-2.0\text{ SD}$: The "magic cutoff." If a child scores two standard deviations below the mean, remedial OT services are warranted.

  • Math Calculation Example:

    • If Mean ($\mu$) = $100$ and Standard Deviation ($\sigma$) = $15$.

    • $1\text{ SD below}$ = $100 - 15 = 85$.

    • $2\text{ SDs below}$ = $100 - 30 = 70$.

    • A score of $70$ or Lower = Qualifies for services.

• Percentile Rank:

  • Ranks performance on a scale of $0$ to $100$.

  • 50th Percentile: Exactly average; better than $50\%$ and worse than $50\%$.

  • Higher Percentile: Represents better performance or a "bigger" measure (e.g., 95th percentile for head size means the head is larger than $95\%$ of peers and smaller than only $5\%$).

  • Formula: $\text{Percent Better} + \text{Percent Worse} = 100\%$.

• Age Equivalency:

  • Stating a child is "performing at a 4-year-old level" is easy for parents to grasp but can be misleading as it does not necessarily imply global delay and must be used with caution.

Core Mnemonics for the OT Process

• The Sequential Order Mnemonic: "You Really Shouldn't Eval Going In Really Drunk."

  • Referral

  • Screen

  • Eval

  • Goal setting

  • Intervention

  • Reevaluation

  • Discharge

• Note: Emphasize the "Reallys" to remember both Referral and Reevaluation.

Questions & Discussion

• Question 1 (Standard Deviation): An OTR is interpreting scores for a 6-year-old. Mean = $100$, $\text{SD} = 15$. Child scores $70$, which is rated as $2\text{ SDs}$ below the mean. What is the conclusion?

  • Response: The child is in need of remedial services. Because the score is at the $2\text{ SD}$ cutoff, it indicates a significant enough delay to warrant OT.

• Question 2 (Percentile Rank): A 5-year-old is evaluated. PDMS results: Gross motor = 5th percentile; Fine motor = 10th percentile. What is the conclusion?

  • Response: $95\%$ of students scored above this student in gross motor skills. Being in the 5th percentile means only $5\%$ of peers scored the same or worse, while $95\%$ performed better.

• Study Tip: Start by reading the last sentence of a long exam question to identify the specific concept (e.g., math interpretation) being tested, which allows you to filter out unnecessary clinical background information.
