This edition of the interRAI Post-Acute Care and Rehabilitation (PAC-Rehab) Assessment Form and User's Manual contains country-specific examples for Canada and uses the English native to Canada. The interRAI PAC-Rehab is a key element of the interRAI Hospital Assessment Systems. It is designed for use among adult patients who require rehabilitation or other forms of post-acute care. This includes patients who are admitted directly to such programs without prior admission to an acute hospital program. The interRAI PAC-Rehab Assessment and Care Planning System is a comprehensive, standardized instrument for evaluating the needs, strengths, and preferences of adult patients who enter a rehabilitation or other form of post-acute program. The interRAI PAC-Rehab is designed primarily to support assessment and care planning but it also serves to monitor progress across an episode of care, facilitating revision of care plans and discharge preparation. The system may also assist in service administration and quality improvement. It is designed to complement and expand prior assessments performed in an acute care setting. Some elements of prior assessments from the interRAI AC and interRAI AC-CGA can be imported directly into the interRAI PAC-Rehab.
