Final answer:
An early or involuntary departure affects the discharge summary by potentially altering the comprehensiveness of information available concerning the client's readiness for discharge and aftercare plans, while still maintaining a need for a summary of treatment and future care recommendations.
Step-by-step explanation:
When a client leaves a treatment program early or involuntarily, the discharge summary may still need to include a comprehensive summary of the client's time in treatment, the reason for discharge, the client's progress and any recommendations for future care. Even if the departure was not planned, the summary should still provide a suitable closure to the episode of care and support any transitions the client may need. However, the specifics of the summary could be affected by the abruptness of the discharge, as there may be less information available on the client's readiness to leave treatment and plans for aftercare.
