Fatores associados à qualidade de vida relacionada à saúde em pacientes em diálise : o foco deve ser o humor?

Abstract

Chronic kidney disease (CKD) patients have compromised health related quality of life (HRQOL) by several reasons. This study aimed to evaluate HRQOL on hemodialysis (HD) and peritoneal dialysis (PD) patients and to identify HRQOL associated factors. Methods: We conducted a transversal study with 215 patients on HD and 58 on PD between July and September 2013, in Sergipe, Brazil. HRQOL was assessed using the Kidney Disease Quality of Life Short Form Instrument- 1.3 (KDQOL-SF), consisting of two cores: specific (KDCS) and generic (RAND-36). Additionally demographic and clinical variables directly related to CKD, factors such as mood, sleep disorders and sexual dysfunction were evaluated through specific instruments. Results: Patients had a mean age of 51 years (SD ± 15.4), mostly men (62%), with low educational (72%) and economic (95%) levels. There was no difference related to HRQOL among dialysis modalities, only PD patients felt more stimulated by caring staff than that on HD (p<0.01). The prevalence of depressive (29%) and anxiety (30%) symptoms, poor quality of sleep (56%), excessive daytime sleepiness (43%) and male (48%) and female (76%) sexual dysfunction were high. Multiple linear regression showed that depressive (R= -0.39 p<0.01, R= -0.48 p<0.01) and anxiety (R = -0.41 p <0.01, R = -0.27 p <0.01) symptoms were independently associated with KDCS and RAND-36. Confirmatory factorial analysis models confirmed the association of mood disorders with low HRQOL. High prevalence of anxiety (30%) and depressive symptoms (29%) were revealed. Conclusion: Patients on HD and PD showed no differences in HRQOL. Mood disorders are independently associated with low HRQOL, with high prevalence of anxiety and depressive symptoms in dialysis patients.
