Pyatt A1 - AB - Older adults living with frailty and multimorbidity interact with multiple care providers and health settings, resulting in fragmented care and information discontinuity. Standardized assessments potentiate integrated care by communicating consistent measures of health information between sectors and providers. We use a pragmatic case example of a theoretical medically complex older adult to illustrate use of interRAI standardized assessments throughout the health journey. The case example represents the assessment findings of a patient accessing care through primary care, the emergency department, home/community care and long-term care. A suite of assessment instruments embedded with decision support algorithms guides nursing care decisions, while a common language and standardized assessment items support effective communication and collaboration among the health team. Successful adoption of integrated and comprehensive assessment tools requires training, engagement, and time to embed processes into practice. interRAI assessments enable integration through a common language, aligning successive assessments across the care continuum.
