This is the protocol for a Campbell systematic review. The aim of this scoping review is to map, describe and characterize the available evidence on the role that formal care might have in complementing informal caregivers role – romantic partners, parallel family members (e.g., [step]siblings, cousins or in-laws) or descendants (e.g., the care-receivers are [step]parents, [step]aunts/uncles, [step]grandparents or in-laws) – when providing care to adults with acquired diseases (physical or neurologic) in domestic settings and will set the ground for future research on this topic. The scoping review questions are the following: (i) What is the existing literature on the complementarity between formal and informal care? (ii) Which are the types of formal cares' services/interventions that have been described in the literature as complementary to informal care, provided to the informal caregiver and/or to the adult being cared for? (iii) Which outcomes have been assessed in the caregiver's physical, psychological, and social health domains, and how have they been measured?
