Self- and staff-reported pain in relation to contextual isolation in long-term nursing home residents with Alzheimer's disease and related dementias.

We evaluated the degree to which contextual isolation in nursing home residents with Alzheimer's disease and related dementias is associated with documented pain using the Minimum Data Set 3.0, a comprehensive resident assessment required of all nursing home residents in the United States. Contextual isolation was defined as having a socially salient characteristic (demographics, habits and interests, and clinical and care dimensions) shared by fewer than 20% of other residents in the same nursing home. Thirteen percent were contextually isolated on multiple characteristics. Among residents self-reporting pain, residents contextually isolated with respect to multiple characteristics were 8% more likely (95% confidence interval: 7% to 9%) to have pain relative to residents who were not contextually isolated on any characteristics. Long-stay nursing home residents with ADRD who live in settings where they were contextually isolated were more likely to have pain relative to those without contextually isolation on any characteristic.
