Financial Toxicity and Kidney Disease in Children and Adults: A Scoping Review.

PURPOSE

Social determinants of health have been related with kidney diseases and their outcomes. Financial toxicity (FT) refers to the negative impact of health care costs on clinical conditions. This scoping review aimed to evaluate the literature linking FT with renal diseases.

PATIENTS AND METHODS

We Included all studies analyzing FT and renal disease recorded in PubMed, Embase and Google Scholar between 2013 and 2023. The research question was formulated with reference to the acronym PCC (Problem, Concept and Contest). For each included study, we considered the study design, the population and main results from different populations with distinct renal conditions and the results were summarized in four tables.

RESULTS

Socioeconomic deprivation was the main cause of FT, and the majority of studies on the relationship between FT and chronic kidney disease (CKD) were conducted in the USA (4 studies evaluated the pediatric population and 6 studies included adults). Three studies reported the impact of FT on nephrolithiasis, and 3 studies analyzed the link between FT and renal tumors. The methods used for detecting FT differed and were based on consultations, questionnaires, expenditures and database records analysis. The COmprehensive Score for financial Toxicity (COST) questionnaire was used in 7 studies (43%), and the prevalence of FT was reported to be high in children and adults.

CONCLUSION

Although the quality of the selected study is limited, due to different populations investigated and heterogeneity in detecting FT, the latter seems to be a frequent finding in people with renal disease. Health care professionals should recognize socioeconomic deprivation as the major cause of FT. Detecting FT could help in prioritizing patient-centered care in populations with renal diseases through the development of strategies aimed at improving care for people with kidney diseases.
