Objective: Comorbid depressive symptoms are common and undertreated in patients with renal diseases. It remains uncertain whether it is an independent risk factor for poor clinical outcome in patients with chronic kidney disease (CKD). This 3-year study investigated the association of depressive symptoms with long-term outcomes, including initiation of dialysis and all-cause mortality, in a population of CKD patients from Taiwan. Methods: This prospective cohort study enrolled 262 CKD subjects, none of whom were undergoing dialysis, from a hospital in Taiwan during 2010-2011 and followed them for 3. years. At enrollment, all subjects underwent a structured interview with the Taiwan Depression Questionnaire to ascertain the baseline presence of depressive symptoms. Primary end points were initiation of dialysis and all-cause mortality. Results: A total of 21.4% of enrolled patients (56/262) reported the presence of depressive symptoms at baseline. After 3-year follow-up, the risk of composite events (dialysis or death) was significantly higher in CKD patients with depressive symptoms than in those without depressive symptoms (adjusted hazard ratio [AHR]. = 2.95, 95% confidence interval [CI]: 1.86-4.72). Depressive symptoms at baseline could independently predict the risk of initiation of dialysis (AHR = 2.25, 95% CI: 1.27-4.98) or all-cause mortality (AHR = 3.08, 95% CI: 1.69-7.06). Conclusions: Depressive symptoms at baseline were independently associated with increased risk of poor clinical outcomes in CKD patients, which suggested that the prompt provision of appropriate psycho-social care may improve the holistic clinical outcomes for CKD patients.
