Service user, carer and provider perspectives on integrated care for older people with frailty, and factors perceived to facilitate and hinder implementation: A systematic review and narrative synthesis.

Similarities and differences in lay and professional stakeholder perspectives on integrated care for OPF and factors perceived to facilitate and hinder implementation were evident. Findings highlight the importance of addressing organisational and system level components of integrated care and factors influencing implementation for OPF. Greater attention needs to be placed on collaboratively involving service users, carers and providers to improve the co-design and implementation of integrated care programmes for this patient population.
