Risk factors and screening instruments to predict adverse outcomes for undifferentiated older emergency department patients: a systematic review and meta-analysis
Carpenter CR, Shelton E, Fowler S, Suffoletto B, Platts-Mills TF, Rothman RE, Hogan TM.. Academic emergency medicine : official journal of the Society for Academic Emergency Medicine, 2015-01-01
Topic: Risk, prevention and care in population studies
Objectives A significant proportion of geriatric patients experience suboptimal outcomes following episodes of emergency department (ED) care. Results A total of 7,940 unique citations were identified yielding 34 studies for inclusion in this systematic review. Studies were significantly heterogeneous in terms of country, outcomes assessed, and the timing of post-ED outcome assessments. None of these risk factors significantly increased the risk of adverse outcome (LR+ range = 0.78 to 2.84). None of these instruments significantly increased (LR+ range for various outcomes = 0.98 to 1.40) or decreased (LR- range = 0.53 to 1.11) the risk of adverse outcomes.

Key findings
- Objectives A significant proportion of geriatric patients experience suboptimal outcomes following episodes of emergency department (ED) care.
- Results A total of 7,940 unique citations were identified yielding 34 studies for inclusion in this systematic review.
- Studies were significantly heterogeneous in terms of country, outcomes assessed, and the timing of post-ED outcome assessments.
- None of these risk factors significantly increased the risk of adverse outcome (LR+ range = 0.78 to 2.84).
- None of these instruments significantly increased (LR+ range for various outcomes = 0.98 to 1.40) or decreased (LR- range = 0.53 to 1.11) the risk of adverse outcomes.
Why it matters
This systematic review of 34 studies found that none of the risk factors or screening instruments significantly increased or decreased the risk of adverse outcomes for older emergency department patients. It reports no significant effect and does not address treating, curing, or preventing Alzheimer's disease.
