Early Identification and Management of Chronic Kidney Disease: A Narrative Review of the Crucial Role of Primary Care Practitioners.

Early-stage (stage 1-3) chronic kidney disease (CKD) has an asymptomatic presentation such that most people with CKD are unaware of their disease status and remain undiagnosed. CKD is associated with multiple long-term conditions (MLTC), or multimorbidity, the most common of these being cardiovascular disease, hypertension, and type 2 diabetes. Primary care practitioners (PCPs) are crucial in the early identification and management of patients with CKD. For individuals at high risk of CKD, measurements of estimated glomerular filtration rate, urine albumin-creatinine ratio, and blood pressure should be obtained regularly and recorded in a timely manner. The importance of lifestyle changes in the prevention and management of CKD should also be highlighted. A recent addition to the treatment of CKD in people with and without type 2 diabetes has been the recommendation by clinical practice guidelines of a sodium-glucose co-transporter 2 (SGLT2) inhibitor alongside a renin-angiotensin-aldosterone system inhibitor as foundational therapy. SGLT2 inhibitors prevent CKD progression and reduce fatal and non-fatal kidney and cardiovascular events, hospitalization for heart failure, and all-cause mortality, and they have a favorable safety and tolerability profile. However, uptake has been slow, particularly in people with CKD without type 2 diabetes. A multifaceted approach is required to ensure that people with CKD receive optimal kidney protection. Measures to raise awareness of the importance of early identification and intervention include local/national campaigns via social media and practice-based education; clinical education programs; integration of clinical decision support tools into electronic health records; detection programs built around electronic health records; and good interdisciplinary communication. PCPs at the forefront of multidisciplinary care are best placed to implement the evidence-based clinical practice CKD guidelines for lifestyle modification and guideline-directed medical therapy.
