Psychiatric service delivery for older people in hospital and residential aged care: An updated systematic review.

The scarcity of high-quality studies examining the effectiveness of old age psychiatry services leaves providers and policy-makers to rely on low-quality evidence when designing services. Future research should consider carefully which outcomes to include, given that staff skill and confidence, length of stay, recommendation uptake, patient- and family-reported experiences, and negative outcomes (i.e. injuries, property damage) are as important as clinical outcomes.
