Managing Speech Therapy Assessments

Managing Speech Therapy Assessments

Structures speech-language pathology evaluation including articulation/phonology, receptive and expressive language, motor speech (apraxia, dysarthria), voice, fluency, cognitive-communication, and swallowing (dysphagia) assessment per ASHA (American Speech-Language-Hearing Association) standards and evidence-based practice guidelines.

Why This Skill Exists

Speech-language pathology encompasses communication and swallowing — two functions critical to safety, quality of life, and rehabilitation participation. Dysphagia mismanagement causes aspiration pneumonia, a leading cause of rehab readmission and mortality. Aphasia and cognitive-communication deficits directly impair rehabilitation participation, informed consent capacity, and discharge safety. ASHA requires SLPs to use standardized assessment tools, document severity using validated scales, and justify treatment with evidence-based rationale. CMS requires SLP documentation to demonstrate medical necessity and skilled assessment need. This skill produces comprehensive SLP evaluation documentation that meets ASHA clinical standards, payer requirements, and medicolegal expectations.

Checkpoint A — Intake Verification

Before beginning SLP assessment, confirm:

Required clinical questions:

• What is the diagnosis affecting communication or swallowing (stroke, TBI, Parkinson disease, head/neck cancer, developmental)?
• What is the onset date and is this acute or chronic?
• What is the patient's premorbid communication status (language spoken, literacy, speech/language history)?
• Is there a swallowing concern (coughing with meals, weight loss, recurrent pneumonia, wet voice quality)?
• What is the current cognitive status (alertness, orientation, command-following)?
• Are there hearing or vision deficits affecting assessment?

Required documents:

• Physician referral specifying SLP evaluation
• Neuroimaging reports (CT/MRI) for neurogenic diagnoses
• Prior SLP evaluation if available
• Modified barium swallow study (MBSS) or FEES results if previously completed
• Audiological evaluation if hearing concern
• Nursing notes on oral intake, diet level, and aspiration precautions

Step 1 — Assess Communication: Language, Speech, and Cognition

Aphasia assessment (post-stroke, neurogenic):

• Boston Diagnostic Aphasia Examination (BDAE): Comprehensive battery classifying aphasia type (Broca, Wernicke, global, anomic, conduction, transcortical) with severity rating 0-5
• Western Aphasia Battery-Revised (WAB-R): Yields Aphasia Quotient (AQ, 0-100); AQ <93.8 = aphasia present
  • Spontaneous speech (fluency, information content)
  • Auditory verbal comprehension (yes/no, word recognition, sequential commands)
  • Repetition (words, phrases, sentences)
  • Naming (object naming, word fluency, sentence completion, responsive speech)
• Boston Naming Test (BNT): 60-item confrontation naming; age-normed scores available

Aphasia classification and severity:

Motor speech assessment:

• Dysarthria: Assess respiratory support, phonation, resonance, articulation, prosody; classify type (spastic, flaccid, ataxic, hypokinetic, hyperkinetic, mixed) per Mayo Clinic system
• Apraxia of speech: Assess volitional control of articulatory movements; groping, trial-and-error, prosodic abnormalities; Apraxia Battery for Adults-2 (ABA-2)

Cognitive-communication assessment:

• Attention: sustained, selective, alternating, divided
• Memory: immediate, delayed, working, procedural
• Executive function: reasoning, problem-solving, planning, self-monitoring
• Social communication: pragmatics, theory of mind, discourse organization
• Instruments: CLQT (Cognitive Linguistic Quick Test), SCATBI (Scales of Cognitive Ability for TBI), RIPA-2 (Ross Information Processing Assessment), FAVRES (Functional Assessment of Verbal Reasoning and Executive Strategies)

Step 2 — Assess Swallowing Function (Dysphagia)

Clinical swallowing examination (bedside):

• Oral mechanism exam: lips, tongue, jaw, velum — symmetry, strength, ROM, coordination
• Oral reflexes: gag, cough, swallow
• Laryngeal function: voice quality (wet/gurgly?), voluntary cough strength, laryngeal elevation on palpation
• Trial swallows: graduated consistency (thin liquid, nectar, puree, mechanical soft, regular) with observation for:
  • Oral containment and bolus formation
  • Timely swallow initiation (>2 seconds delay is abnormal)
  • Laryngeal elevation adequacy
  • Coughing, throat clearing, or wet voice quality post-swallow
  • Residual in oral cavity post-swallow

Instrumental assessment (when bedside is insufficient):

• Modified Barium Swallow Study (MBSS/VFSS): Fluoroscopic visualization of oropharyngeal swallow with graduated consistencies and volumes per MBSImP (Modified Barium Swallow Impairment Profile)
• FEES (Fiberoptic Endoscopic Evaluation of Swallowing): Transnasal endoscopic visualization of pharyngeal and laryngeal structures during swallow
• Document: penetration, aspiration (with or without cough response), residue location and severity, effective compensatory strategies tested

Standardized dysphagia scales:

• Penetration-Aspiration Scale (PAS, Rosenbek): 1-8 scale
  • 1: Material does not enter airway
  • 2: Material enters airway, remains above vocal folds, is ejected
  • 3-5: Penetration with varying ejection
  • 6: Material passes below vocal folds, is ejected (aspiration with cough)
  • 7: Material passes below vocal folds, is not ejected despite effort
  • 8: Material passes below vocal folds, no effort to eject (silent aspiration)
• IDDSI (International Dysphagia Diet Standardisation Initiative): Document recommended diet level using IDDSI framework (Levels 0-7)
  • Level 0: Thin liquids
  • Level 1: Slightly thick
  • Level 2: Mildly thick
  • Level 3: Liquidised/moderately thick
  • Level 4: Pureed/extremely thick
  • Level 5: Minced and moist
  • Level 6: Soft and bite-sized
  • Level 7: Regular/easy to chew

Step 3 — Assess Voice and Fluency When Indicated

Voice assessment (if voice disorder is referral concern):

• Perceptual voice quality: CAPE-V (Consensus Auditory-Perceptual Evaluation of Voice) — rates overall severity, roughness, breathiness, strain, pitch, loudness on 100mm visual analog scale
• Acoustic measures: fundamental frequency, jitter, shimmer, harmonic-to-noise ratio (via Praat or similar software)
• Maximum phonation time (MPT): sustained "ah" — normal ≥15 seconds for adults; <10 seconds suggests glottic insufficiency
• S/Z ratio: >1.4 suggests vocal fold pathology
• Refer for laryngoscopy/stroboscopy if structural pathology suspected

Fluency assessment (stuttering):

• Stuttering Severity Instrument-4 (SSI-4): frequency, duration, physical concomitants; yields severity rating
• Disfluency type analysis: part-word repetitions, prolongations, blocks (core behaviors) vs. interjections, revisions (non-core)
• Percent syllables stuttered (%SS): <1% = within normal limits; 1-5% mild; 5-10% moderate; >10% severe
• Impact measures: Overall Assessment of the Speaker's Experience of Stuttering (OASES)

Step 4 — Synthesize Findings and Determine Severity

For each area assessed, assign a severity rating:

ASHA National Outcome Measurement System (NOMS) Functional Communication Measures (FCM):

• 7-point scale per domain (1 = least functional, 7 = most functional)
• Rate separately: spoken language comprehension, spoken language expression, reading, writing, swallowing, cognitive communication, motor speech

Integrate findings across domains: "Patient presents with moderate non-fluent (Broca) aphasia (WAB AQ = 56.4) characterized by effortful, agrammatic verbal output with relatively preserved auditory comprehension at the sentence level. Concomitant moderate oropharyngeal dysphagia with delayed swallow initiation and reduced hyolaryngeal excursion; PAS score 5 on thin liquids, PAS 2 on nectar-thick; chin-tuck strategy reduces penetration. IDDSI Level 2 liquids and Level 6 solids recommended. Cognitive-communication screening reveals intact orientation and attention with impaired working memory and verbal reasoning."

Step 5 — Formulate Recommendations and Treatment Plan Justification

• Diet and liquid recommendations (IDDSI levels) with compensatory strategies
• Communication modality recommendations (verbal, AAC device, communication board, writing)
• Therapy frequency and duration with clinical justification
• Referrals: audiology, ENT/laryngology, neuropsychology, dentistry as indicated
• Aspiration precautions and nursing/caregiver education plan
• Prognosis with supporting factors (age, onset, severity, cognitive status, motivation)

Checkpoint B — Pre-Finalization Review

Before finalizing SLP assessment documentation:

• All relevant communication domains assessed (language, speech, cognition, voice, fluency as indicated)
• Standardized instruments administered with scores and severity ratings
• Aphasia type and severity classified with WAB or BDAE data
• Swallowing assessment completed (clinical and/or instrumental) with diet recommendation
• PAS score documented if instrumental study completed
• IDDSI diet level specified with liquid and solid texture recommendations
• Cognitive-communication screening completed for neurogenic diagnoses
• Severity ratings assigned using standardized scales
• Recommendations include diet, communication modality, therapy plan, and referrals
• Documentation meets ASHA clinical practice standards

Quality Audit

• Standardized assessments used with published norms and scores documented
• Aphasia classification supported by WAB/BDAE subscale pattern
• Dysarthria typed using Mayo Clinic classification system
• Swallowing recommendations specify IDDSI levels for both solids and liquids
• Aspiration risk documented with PAS score and strategy effectiveness
• Cognitive-communication deficits linked to functional impact (rehab participation, safety, discharge)
• All [VERIFY] flags resolved or escalated to physician
• Voice assessment includes perceptual and at least one objective measure
• ASHA NOMS severity ratings assigned for treatment planning
• Documentation signed with SLP credentials (CCC-SLP)

Guidelines

• SLP scope of practice per ASHA includes communication (language, speech, voice, fluency, cognitive-communication) and swallowing — assess all relevant domains
• Clinical bedside swallow evaluation alone has limited sensitivity for silent aspiration — recommend instrumental study (MBSS/FEES) when aspiration risk is high or clinical exam is equivocal
• IDDSI is the international standard for diet texture naming — use IDDSI terminology, not facility-specific terms
• Never recommend a diet level without assessment; do not maintain NPO status beyond clinical necessity without reassessment plan
• Aphasia is a language disorder, not a cognitive or hearing disorder — assess and document the distinction
• Apraxia of speech and dysarthria are motor speech disorders requiring different treatment approaches — accurate classification is essential
• Cognitive-communication deficits (attention, memory, executive function) affect all rehabilitation disciplines — SLP findings inform the interdisciplinary team
• AAC (augmentative and alternative communication) assessment is within SLP scope and should be initiated early for patients with severe expressive impairment
• Medicare requires SLP services to be provided by or under the supervision of a qualified SLP (CCC-SLP or equivalent state licensure)
• Document all diet changes in the medical record with nursing notification and physician order — diet changes are medical orders
