Problem: No empirical data on the sleep pattern of patients with an implantable left ventricular assist device (LVAD) exists. Conceptualized within the self-care deficit nursing theory, this study examined the patient's ability to meet the rest component of the universal self-care requisite in two heath states (pre and post LVAD). Specifically, we described the variables sleep efficiency (SE), sleep fragmentation (SF), sleep quality (SQ), and daytime sleepiness (DS), and determined the change in the pattern of these variables pre and up to one month post implantation of an LVAD. Methods: Seven males and three females (N=10), ages 30 to 70 years, all with advanced heart failure (Stage D), participated in this study. A descriptive, repeated measures design was employed. SE and SF variables were measured using wrist actigraphy. SQ and DS variables were measured using Subjective Sleep Quality and Stanford Sleepiness Scales. Measurements were made for three consecutive days and nights at four points in time: pre-implant (T1), one (T2), two (T3) and four (T4) weeks post-implant. Data were analyzed using descriptive statistics and repeated measures ANOVA. Results: Low SE, high SF and low SQ mean scores found at T1 to T4 (Table). No significant change (p>0.05) in SE and SF scores. However, DS mean scores peaked at T2, dropped significantly at T3 (p=0.006), and plateaued at T4 (Figure). Upward trend in SQ mean scores at T1 to T4, but the change in score from baseline (T1) was only significant at T4 (p=0.015, Figure). Conclusion/Implication: Subjects are not meeting the requisite 'rest' adequately, manifested by disturbed sleep patterns pre and up to one month post LVAD. This first empirical data will be the basis for further research and knowledge development on "self-care" of patients living with long-term implantable LVADs.
