Instruments in general practice to identify and to measure (over)burden due to informal care for caring relatives: a scoping review protocol

Introduction Family caregivers provide by far the largest share of long-term, unpaid care for their primarily elderly and chronically ill relatives or friends. This is associated with a higher risk of psychological and physical overload for the caregivers due to the persistently high time, financial and emotional burden. Recognising the effects of persistent burden on caring relatives at an early stage significantly contributes to the appropriate coordination of available resources and mediation of individual support to maintain a functional caring relationship without excessive demands. General practitioners are usually responsible for the early detection of burden arising from informal care and the coordination of adequate measures. The objective of this review is to give an overview of instruments to identify and measure (over)burden of caring relatives in German general practice and to describe their characteristics. Methods and analysis We used the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist in addition to the Joanna Briggs Institute Reviewer's Manual to describe the aims and methods of the planned scoping reviews. This protocol has been registered with Open Science Framework (OSF), https://osf.io/9ce2k. Two reviewers will run the search to identify studies in four databases (PubMed, LIVIVO, the Cochrane Library and CINAHL) in June and July 2023. Abstracts, titles and full-text publications will be screened to extract data from each included study using a data extraction form. Additionally, an overview of all studies including main study characteristics and detailed information on identification instruments will be given to map the different instruments and tools and to clarify statements concerning their use and practicability in general practice. Ethics and dissemination Ethical approval or consent to participate is not required, as data in this study consists of published studies and not individual data from human or animal participants. Dissemination will consist of publications, presentations and other knowledge translation activities.
