Understanding the Current Landscape of Kidney Disease in Canada to Advance Precision Medicine Guided Personalized Care

Abstract
in English, French

Purpose of review: To understand the impact of kidney disease in Canada and the priority areas of kidney research that can benefit from patient-oriented, precision medicine research using novel technologies.

Sources of information: Information was collected through discussions between health care professionals, researchers, and patient partners. Literature was compiled using search engines (PubMed, PubMed central, Medline, and Google) and data from the Canadian Organ Replacement Register.

Methods: We reviewed the impact, prevalence, economic burden, causes of kidney disease, and priority research areas in Canada. After reviewing the priority areas for kidney research, potential avenues for future research that can integrate precision medicine initiatives for patient-oriented research were outlined.

Key findings: Chronic kidney disease (CKD) remains among the top causes of morbidity and mortality in the world and exerts a large financial strain on the health care system. Despite the increasing number of people with CKD, funding for basic kidney research continues to trail behind other diseases. Current funding strategies favor existing clinical treatment and patient educational strategies. The identification of genetic factors for various forms of kidney disease in the adult and pediatric populations provides mechanistic insight into disease pathogenesis. Allocation of resources and funding toward existing high-yield personalized research initiatives have the potential to significantly affect patient-oriented research outcomes but will be difficult due to a constant decline of funding for kidney research.

Limitations: This is an overview primarily focused on Canadian-specific literature rather than a comprehensive systematic review of the literature. The scope of our findings and conclusions may not be applicable to health care systems in other countries.

Justification: Cette étude visait à mieux comprendre l’impact de l’insuffisance rénale au Canada et à déterminer les domaines de recherche prioritaires en santé rénale qui pourraient tirer profit des recherches axées sur le patient qui sont menées en médecine de précision avec de nouvelles technologies.

Sources: L’information provient de discussions entre les professionnels de la santé, les chercheurs et les patients partenaires. La littérature a été compilée à l’aide de moteurs de recherche (PubMed, PubMed central, Medline et Google) et de données provenant du Registre canadien des insuffisances et des transplantations d’organes.

Méthodologie: Nous avons examiné les répercussions, la prévalence, le fardeau économique et les causes des maladies rénales, ainsi que les domaines prioritaires de la recherche au Canada. Après avoir examiné les domaines de recherche prioritaires en santé rénale, nous avons décrit les possibles orientations de recherche pouvant intégrer des initiatives de la recherche axée sur le patient menée en médecine de précision.

Principaux résultats: L’insuffisance rénale chronique (IRC) demeure l’une des principales causes de morbidité et de mortalité dans le monde et elle exerce une forte pression financière sur le système de santé. Malgré le nombre croissant de personnes atteintes d’IRC, le financement de la recherche fondamentale en santé rénale reste à la traîne des autres maladies; et le financement actuel favorise les stratégies existantes pour le traitement clinique et l’éducation des patients. L’identification de facteurs génétiques liés aux diverses formes de néphropathies dans les populations adultes et pédiatriques fournit une compréhension mécanistique de la pathogenèse de la maladie. L’attribution des ressources et du financement à des initiatives de recherche personnalisées existantes et connues pour leur rendement élevé pourrait avoir une incidence considérable sur les résultats de la recherche axée sur le patient, mais elle sera difficile compte tenu de la diminution constante du financement de la recherche en santé rénale.

Limites: Il s’agit d’un portrait axé principalement sur la littérature canadienne et non d’un examen systématique complet de la littérature. La portée des résultats et conclusions pourrait ne pas s’appliquer aux systèmes de santé d’autres pays.

Keywords: Canada; chronic kidney disease; health care costs; patient-centered research; precision medicine; research funding.
