Chronic kidney disease (CKD) is associated with poor outcomes among stroke survivors. In Africa, where both stroke and CKD incidence rates are escalating, little, if anything, is known about the burden of CKD among stroke survivors.To assess the frequency and factors associated with CKD among stroke survivors by primary stroke types.Stroke registry data were prospectively collected on consecutively encountered stroke survivors seen at an out-patient clinic in Ghana between January 2018 and March 2020. We calculated estimated glomerular filtration rate (eGFR) using the CKD-EPI formula and defined CKD as eGFR60ml/min. Factors associated with CKD were assessed using multiple logistic regression modelling.Among 759 stroke survivors, 159 had CKD giving a prevalence of 21.0% (95%CI: 18.1% - 23.8%). The mean age of those with CKD was 61.6 ± 14.2 years compared with 57.5 ± 13.6 years, p=0.0007 among those without CKD. Five factors remained significantly associated with CKD with the following adjusted odds ratio (aOR and 95% CI). Age per decile rise 1.30 (1.13-1.50), male sex 1.99 (1.36-2.93), rural dwelling residence 1.95 (1.06-3.59), prior use of antihypertensive meds before index stroke onset 1.63 (1.08-2.47), and number of antihypertensive medication classes 1.25 (1.06-1.45).1 in 5 stroke survivors have evidence of chronic kidney disease in this Ghanaian study. Targeted interventions focusing on optimizing blood pressure control and rural dwellers may mitigate their risk for adverse outcomes.
