Factors Associated With Mood Transitions Among Older Canadian Long-Term Care Residents: A Multistate Transition Model.

Abstract

Objectives: This study examines the complex transitions between the different mood states and absorbing states out of long-term care settings, as well as the factors affecting those transitions.

Design: A retrospective longitudinal analysis of older residents in Canadian long-term care homes in 3 provinces.

Setting and participants: Residents residing in long-term care homes in 3 Canadian provinces (Alberta, British Columbia, and Ontario) over a 10-year period from January 2010 to February 2020, with an age of at least 65.

Methods: We used a 1-step Markov multistate transition model to examine transitions in mood over time as well as the factors affecting those transitions using the standardized interRAI MDS 2.0 comprehensive health assessment. The MDS 2.0 assessments are completed by trained assessors within 2 weeks of the resident's admission.

Results: Our results showed that 46% of residents initially present with no mood disturbance on admission and 31% with mild mood disturbance on admission and 23% with moderate/severe mood disturbance on admission. Factors associated with worsening of mood include aggressive behavior; health instability; impaired cognition; major comorbidities; pain or poor sleep; conflict with family, friends, or other residents; and anxiety. Of the facility-level attributes, Alberta was associated with worsening of mood.

Conclusions and implications: Our study identified key factors influencing mood transitions, highlighting pain and aggressive behavior as significant contributors to worsening mood, both of which are modifiable through targeted interventions. The findings suggest substantial opportunities for mood improvement in long-term care settings.
