Illness perception in patients with chronic kidney disease and kidney failure: a scoping review protocol

Abstract

Introduction Patient education is a crucial component in the management of chronic kidney disease (CKD); however, many education programmes do not tailor to patients’ disease-related belief and emotional reactions. According to Leventhal’s self-regulation model, such beliefs and reactions, known as illness perceptions, are a part of patients’ understanding of their disease and treatment-related actions. The existing research of illness perception in the field of nephrology has been heterogenous in terms of study outcomes and in study population; and the evidence of how illness perceptions affect behavioural and decisional outcomes is limited. This scoping review aims to map and summarise the evidence of published literature on illness perception among patients with CKD not yet treated by dialysis and kidney failure.Methods and analysis This study bases its approach on Joanna Brigg’s Institute Guidelines on scoping review methods. The search strategy was developed together with a medical information specialist. Searches will be performed on acceptance of publication in the following databases: PubMed, EMBASE, PsycINFO via Ovid, Scopus and the Cumulative Index to Nursing and Allied Health Literature. Searches will be run without incorporating a date restriction in order to capture content from the databases’ inception to present day. Search terms including ‘illness perception’, ‘kidney disease’ and ‘kidney failure’ will be screened in titles and abstracts. Two independent researchers will screen the abstracts and full text for full eligibility. We will include studies focusing on illness perception of patients with CKD with estimated glomerular filtration rate <60 mL/min/1.73 m2, kidney failure or recipients of kidney transplant. We will exclude patients <18 years of age, patients with acute kidney injury and non-English articles. All demographic data, study design and study findings will be collected and analysed using a data abstraction tool.Ethics and dissemination This study does not require internal review board approval. We will present the findings of this scoping review in a peer-reviewed journal.
