Abstract

Background: Renal Disease is a progressive and often asymptomatic condition that significantly contributes to both morbidity and mortality. The aim of this study is to evaluate the prevalence of Chronic Kidney Disease among the island’s population over a seven-month period, a task of particular relevance given that all patients were exclusively monitored at the General Hospital given the lack of private nephrology care. 


Method and Material: A cross-sectional descriptive study was conducted with a sample of patients from the outpatient nephrology clinic and Dialysis Unit of the General Hospital of Chios "Skylitsio" for the period from October 2023 to April 2024.


Results: The majority of patients were men and exhibited higher rates of advanced stages of Chronic Kidney Disease compared to women. The age distribution showed that older patients primarily visited the clinic, accounting for 56.67% of total patients. Stage 3 was the most prevalent (38.65% of total patients). The prevalence of patients undergoing hemodialysis in Chios was identical to the national prevalence (0.12%). The majority of patients were men (72.5%), with the most affected age group being 71–80 years (37.1%). Most had been receiving hemodialysis for 1 to 7 years (80.65%). The leading cause of end-stage renal disease requiring hemodialysis was nephropathy of unknown etiology (37.1%).


Conclusions: The prevalence of chronic kidney disease in Chios was generally higher compared to both the national average and global prevalence.
