What is the recommended evaluation and treatment for a 3 year 6 month old child with speech delay?

Evaluation and Management of Speech Delay in a 3.5-Year-Old Child

A 3.5-year-old child with speech delay requires immediate referral for comprehensive audiologic evaluation and speech-language pathology assessment, while simultaneously initiating early intervention services without waiting for diagnostic completion. 1

Initial Assessment and Screening

Comprehensive hearing evaluation is the first critical step for any child presenting with speech delay, as hearing loss is a common and treatable cause. 2, 1

• At 3.5 years of age, this child should undergo play audiometry performed by an audiologist, which involves having the child perform a task (placing a peg in a pegboard or dropping a block in a box) in response to stimulus tones. 2
• The evaluation must include air-conduction and bone-conduction thresholds for pure tones, speech detection/recognition thresholds, and speech understanding measurement. 2
• Ear-specific testing using insert earphones is essential to detect unilateral or asymmetrical hearing loss. 2
• Do not rely on tympanometry, pneumatic otoscopy, or caregiver judgment as substitutes for formal audiologic testing. 2

Laboratory Evaluation

Thyroid function testing (TSH and free T4) should be performed as part of the initial workup, as subclinical hypothyroidism can manifest as speech and language delays and affects cognitive development. 3

• TSH values above 6.5 mU/L are considered elevated and require further evaluation. 3
• This testing is particularly important given the American Academy of Pediatrics recommendation that thyroid function studies are reasonable for children with developmental issues. 3

Speech-Language Pathology Evaluation

Immediate referral to a speech-language pathologist is mandatory and should occur concurrently with audiologic assessment, not after. 1, 4

• The evaluation should assess oral-motor functioning, articulation, and both expressive and receptive language abilities using validated assessment tools. 1
• Comprehensive speech and language evaluation is recommended whenever a parent or caregiver expresses concern, regardless of screening results. 2

Developmental and Medical Screening

Screen for autism spectrum disorder, as delayed speech and language are common early signs, particularly if there are concerns about social communication or regression. 1

• Evaluate for global developmental delays, as speech delay may be part of a broader developmental issue requiring comprehensive cognitive, motor, and social-emotional assessment. 1, 4
• Consider whether the child has any risk factors for hearing loss or developmental delays, including history of otitis media with effusion (OME), which can cause hearing loss averaging 28 dB HL. 2

Immediate Intervention

Refer to early intervention services immediately without waiting for complete diagnostic evaluation. 1

• Speech-language therapy has good evidence of effectiveness, particularly for expressive language disorders, and should begin as soon as possible. 1, 4
• The intervention plan should be coordinated through local early childhood services or the school system for needs assessment. 1
• For severe delays, consider alternative or augmentative communication systems. 1
• If additional motor delays are present, include physical and occupational therapy referrals. 1

Special Considerations for Otitis Media

If the child has a history of recurrent or chronic otitis media with effusion:

• Children with bilateral OME for 3 months or longer AND documented hearing difficulties should be offered tympanostomy tube insertion. 2
• Hearing difficulty can be documented through age-appropriate audiologic testing or validated caregiver questionnaires assessing hearing problems, speech delay, or poor pronunciation over the past 4 weeks. 2
• The average hearing loss from OME is 28 dB HL, but approximately 20% of children have thresholds exceeding 35 dB HL, which significantly impacts speech and language acquisition. 2

Follow-Up and Monitoring

Regular reassessment of developmental progress is essential, with adjustments to the intervention plan as needed. 1

• Children with speech delay during preschool years often face long-term developmental difficulties, warranting close follow-up through school age. 5
• If OME is present, re-examine at 3-6 month intervals until effusion resolves, significant hearing loss is identified, or structural abnormalities are suspected. 2

Critical Pitfalls to Avoid

• Do not rely solely on clinical observation or judgment—standardized screening tools are essential, as clinical impression alone misses 45% of children eligible for early intervention. 1
• Do not delay intervention while awaiting complete diagnostic evaluation—early intervention services should begin immediately. 1
• Do not substitute auditory brainstem response (ABR) or otoacoustic emissions for behavioral pure tone audiometry in routine evaluation, as these test auditory pathway integrity, not functional hearing. 2
• Do not assume normal hearing based on office observation—formal audiologic testing is mandatory regardless of how well the child seems to hear. 5
