P1219SLEEP AND PERITONEAL DIALYSIS

Abstract

Abstract Background and Aims Sleep is considered a basic human need according to Maslow. It helps in the individual‘s physical and psychological recovery. Nowadays, sleep disturbances are an increasingly frequent reality and they interfere negatively with quality of life. Poor sleep quality has a negative impact on the individual’s health (attention, memory, Diabetes, Hypertension, immune system depression, mortality). Peritoneal dialysis (PD) may be an additional insult that is disturbing to its quality. The aim of the study was to assess the quality and health of sleep in PD patients. Method We carried out a single-center study in 35 prevalent PD patients. We used the Pittsburgh Sleep Quality Scale (PSQI), which evaluates seven components (subjective quality, latency, duration, usual efficiency of sleep and sleep changes, medication use and daytime dysfunction) and which considers a good sleep quality when PSQI ≤5. We used a sleep health scale assessed by SATED PT (validated for the Portuguese population) and which considers 0 poor sleep health and 30 good sleep health. Each patient answered both PSQI and SATED-PT questionnaires. Demographic and clinical variables were analyzed. Continuous variables are presented as means (standard deviation) or medians (interquartile range), depending on normality; categorical as frequencies. Univariate analysis was performed. STATA software was used and p <0.05 was considered significant. Results Our cohort has 18 (51%) women, 34 (97%) Caucasians, mean age 49 ± 15 years, median dialysis time of 20.5 (8-33) months; 4 (11%) had a history of attempted construction of arteriovenous fistula and 7 underwent a short period of hemodialysis before starting PD (median 60 months). Charlson's median score was 4 (2-5). 21 patients (60%) were on automated PD, 14 on manual, 18 on Baxter system and 17 on Fresenius system. Regarding sleep quality, the average obtained on the PSQI scale was 7 ± 3.4 and 60% had values> 5. We found no correlations between these parameters and the demographic and clinical variables studied. We found that 36.4% of patients wake up earlier than expected, 43.8% get up to go to the bathroom, 30% have nightmares, 20% have pain while sleeping, 23.5% depend on sleeping medication, 34.3% have restless legs, all these parameters in a frequency greater than 3x week. Regarding sleep health, the mean of the SATED scale was 22 ± 5.8 and only 2 patients (5.7%) had values <10. We found a negative correlation between the SATED value and time on dialysis (p = 0.03) and a positive correlation with BMI (p = 0.04). Only 1 patient with normal values lived alone (p = 0.03). None of these scales (and respective sub-scales) correlated with the PD modality. Conclusion In conclusion, the majority of our patients have poor sleep quality but the small sample size limits further conclusions from this study.
