Under what condition is proxy input permissible?

• A. Always required
• B. If patient unable to provide response
• C. Only for non-English speakers
• D. After patient provides consent

Answer: (B)

Proxy input is permissible when the patient cannot provide the response themselves. In OASIS assessments, the patient’s own report is preferred, but if the patient is unable to respond due to cognitive impairment, severe illness, or other communication limitations, a knowledgeable proxy (such as a family member or caregiver) may relay information based on observed status and the patient’s typical functioning. The proxy should reflect the patient’s status as accurately as possible and only be used when direct participation isn’t possible. Proxy input isn’t limited to language barriers; it applies to any situation where the patient cannot report. Consent matters, but the key condition is the patient’s inability to respond.
