Background: The increasing incidence of chronic kidney disease (CKD) globally highlights the importance of early targeted screening of at-risk persons in primary healthcare settings. This study investigated the early detection of CKD among Aboriginal and Torres Strait Islander patients attending an urban primary healthcare service.
Methods: Routine data extracted for all patients with an active electronic medical record on 7 December 2017 were used to identify patients who were eligible to have a kidney health check (KHC), comprising estimated glomerular filtration rate (eGFR) and urine albumin creatinine ratio (UACR) tests. A subsequent manual search of electronic health records identified the presence of CKD risk factors and follow-up KHCs.
Results: Of the 1181 eligible patients, 171 (15%) had a complete initial KHC. Of the eight patients with an initial abnormal eGFR, two (25%) had a repeat eGFR assessment within 3 months to confirm the presence of CKD. Of the 30 patients who had an initial abnormal UACR result, three (10%) had at least one repeat UACR measurement within 3 months. In patients with diabetes and/or hypertension and a normal initial KHC, 51% had a repeat eGFR and 36% had UACR within the recommended time frame of 12 months. Similar findings were observed for the recommended time frame of 24 months in patients without diabetes or hypertension.
Conclusion: Accurate documentation of risk factors for CKD and processes to address the barriers to implementation of Kidney Health Australia guidelines will assist in preventing or delaying progression of CKD.
