A mixed-methods systematic review of nurse-led interventions for people with multimorbidity.

This is the first mixed-methods review which includes all types of nurse-led interventions for multimorbidity and does not focus on specific comorbidities or elderly/frail populations. Using adapted consensus-developed frameworks for interventions and outcomes, we have identified the common features of interventions and their overall typology. We suggest these interventions are of value to patients and healthcare systems but require localization and granular evaluation of their components to maximize potential benefits.
