To determine if family caregiver involvement in interventions with patients with delirium improves patient outcomes.
A search of three databases (Medline-Ovid, CINAHL and Embase) was conducted. Eligibility criteria included adult patients and involvement of family caregivers in any delirium intervention. Data were extracted from each study (determined by PEDro scale) using a customised form. A meta-analysis was undertaken which compared the length of hospital stay and duration of delirium. PROSPERO registration number is CRD42017077650.
Five studies involving 505 participants published over a 5-year period were suitable for inclusion. Low-level evidence demonstrated family caregiver involvement may reduce caregiver's anxiety and hospital staff viewed administration of education to family caregivers as efficient. Meta-analysis suggested family interventions reduce length of hospital stay for patients with delirium. It remains unclear if it affects the duration of delirium.
Family caregivers providing interventions to patients with delirium can improve patient outcomes.
