Accreditation bodies, such as The Joint Commission (TJC) and URAC, require organizations to define the client population(s) they serve and the age groups within that client population. The healthcare organization is responsible for evaluating staff competence to meet the needs and behaviors of the age groups it serves.
Many organizations define the following four client population categories:
- Neonatal and infant
- Child and adolescent
- Adult
- Geriatric
Each age group possesses unique characteristics:
- Physical, including motor/sensory attributes
- Psychosocial and developmental tasks
- Cognitive and intellectual functioning
- Major fears and stressors
Case managers apply age-specific considerations when:
- Performing a physical assessment and interpreting the findings
- Assessing and addressing nutritional status
- Communicating
- Involving the client in care and decision-making
- Providing instruction and education
- Selecting medical equipment and supplies
- Assisting the patient to cope
- Assessing risk for injury and instituting preventive measures
