Evaluation and Management of ADL Disorder
Patients with ADL impairment should undergo structured assessment using validated tools (ADL scale for basic activities, IADL scale for instrumental activities) to quantify functional deficits, followed by targeted interventions including occupational therapy, environmental modifications, and treatment of underlying conditions affecting function. 1
Assessment Framework
Basic ADL Assessment
Evaluate six core self-care activities using the ADL scale 1:
- Bathing
- Dressing
- Toileting
- Transfer (mobility)
- Continence
- Feeding
Score each activity based on actual assistance received (not capability), ranging from 0 (complete independence) to 6 (complete dependence in all functions). This assessment should be performed by trained personnel and repeated periodically to track changing needs 1.
Instrumental ADL Assessment
Use the IADL scale to evaluate seven complex activities 1:
- Walking and transportation
- Meal preparation
- Housework
- Medication management
- Financial management
- Shopping
- Communication/telephone use
Any requirement for assistance in IADL or ADL domains indicates functional impairment requiring intervention 2.
Management Algorithm
1. Identify Underlying Causes
Assess five critical domains that impact ADL performance 1:
- Cognition: Screen with validated tools; cognitive impairment directly affects ADL capacity
- Comorbid medical conditions: Treat appropriately as these worsen functional decline
- Mood disorders: Screen for depression/anxiety using standardized scales
- Physical function: Evaluate mobility, fall risk, and strength
- Caregiver status: Assess caregiver burden and available support
2. Implement Targeted Interventions
For patients with confirmed ADL difficulties 3:
- Occupational therapy referral (Grade B evidence): Formulate and document a management plan addressing specific functional deficits
- Physical therapy: For mobility impairments, gait training, balance, and strength (mobilize as early and frequently as possible)
- Environmental modifications: Task simplification, appropriate lighting, visual cues (signs, pictures, arrows) to aid orientation 4
- Assistive devices: Based on therapist recommendations
For IADL impairments specifically 2: Consider treatment modifications in complex care situations:
- More frequent monitoring (weekly or biweekly)
- Simplified medication regimens
- Home safety evaluations
- Nutritional support if weight loss present
3. Address Safety Concerns
Critical safety interventions 1:
- In-home assessment: Identify environmental hazards and needed supports
- Fall prevention: Check orthostatic blood pressure, adjust medications, provide prevention education
- Driving evaluation: Report to motor vehicle department per local law if cognitive/functional impairment affects driving safety
- Abuse monitoring: Report suspected abuse to appropriate authorities
4. Provide Support Services
Essential referrals 1:
- Social services for community resources
- Nutritionist/dietician if nutritional status poor
- Support organizations (disease-specific associations)
- Home health services or visiting nurse
- Adult day care programs
- Respite care for caregivers
5. Establish Care Planning
- Specific functional goals with patient/family input
- Advance directives and surrogate decision-makers
- Regular reassessment schedule (every 6 months minimum)
- Caregiver education on techniques to maximize function
- Contingency plans for functional decline
Common Pitfalls to Avoid
Do not rely on patient self-report alone - ADL assessment must include caregiver input and direct observation, as patients with cognitive impairment often overestimate their abilities 1.
Do not delay therapy referrals - Early occupational and physical therapy intervention prevents further functional decline and maintains independence longer 3.
Do not overlook treatable causes - Depression, medication side effects, pain, and undertreated medical conditions frequently contribute to ADL decline and are modifiable 1.
Do not use indwelling catheters as initial management for incontinence - this increases infection risk and should be avoided 3.
Monitoring and Reassessment
Repeat ADL/IADL assessments periodically using the same validated instruments to:
- Track progression of functional decline
- Adjust interventions based on changing needs
- Determine need for increased support services
- Guide discussions about level of care 1
The frequency of reassessment depends on disease stage and stability, but every 6 months is recommended as a baseline 1.
