Context
In most resource-rich countries, a large and growing proportion of older adults with complex needs will die while in a residential aged care (RAC) facility.Objectives
This study describes the impact of facility size (small/large), ownership model (profit/nonprofit) and provider (independent/chain) on resident comfort, and symptom management as reported by RAC staff.Methods
This retrospective “after-death” study collected decedent resident data from a subsample of 51 hospital-level RAC facilities in New Zealand. Symptom Management at the End-of-Life in Dementia and Comfort Assessment in Dying at End of life with Dementia (SM-EOLD and CAD-EOLD, respectively) scales were used by RAC staff who were closely associated with 217 deceased residents. Data collection occurred from January 2016 to February 2017.Results
Results indicated that residents of large, nonprofit facilities experienced greater comfort at the end of life (CAD-EOLD) as indicated by a higher mean score of 37.21 (SD = 4.85, 95% CI = 34.4, 40.0) than residents of small for-profit facilities who recorded a lower mean score of 31.56 (SD = 6.20, 95% CI = 29.6, 33.4). There was also evidence of better symptom management for residents of chain facilities, with a higher mean score for symptom management (SM-EOLD total score) recorded for residents of chain facilities (mean = 28.07, SD = 7.64, 95% CI = 26.47, 29.66) than the mean score for independent facilities (mean = 23.93, SD = 8.72, 95% CI = 21.65, 26.20).Conclusion
Findings suggest that there are differences in the quality of end-of-life care given in RAC based on size, ownership model, and chain affiliation. 相似文献In this review, combined post-mortem brain magnetic resonance imaging (MRI) and histology studies are highlighted, illustrating the relevance of translational approaches to define novel MRI signatures of neuropathological lesions in neuroinflammatory and neurodegenerative disorders. Initial studies combining post-mortem MRI and histology have validated various MRI sequences, assessing their sensitivity and specificity as diagnostic biomarkers in neurologic disease. More recent studies have focused on defining new radiological (bio)markers and implementing them in the clinical (research) setting. By combining neurological and neuroanatomical expertise with radiological development and pathological validation, a cycle emerges that allows for the discovery of novel MRI biomarkers to be implemented in vivo. Examples of this cycle are presented for multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, and traumatic brain injury. Some applications have been shown to be successful, while others require further validation. In conclusion, there is much to explore with post-mortem MRI and histology studies, which can eventually be of high relevance for clinical practice.
