Kl. Grady et al., Improvement in quality of life outcomes 2 weeks after left ventricular assist device implantation, J HEART LUN, 20(6), 2001, pp. 657-669
Background: The successful use of left ventricular assist devices (LVADs) a
s a bridge to heart transplantation has prompted our examination of quality
of life (QOL) outcomes. The purposes of this study are to describe QOL in
patients 1 to 2 weeks after LVAD implantation and to compare QOL in a small
er cohort of patients from before to 1 to 2 weeks after surgery.
Methods: Data were collected from a convenience sample of 81 patients who c
ompleted booklets of questionnaires that measure domains of QOL 1 to 2 week
s after LVAD insertion and from 30 of 81 patients who completed booklets at
both the preimplantation and post-implantation periods. Patients completed
booklets of 6 to 8 self-reporting instruments, with acceptable reliability
and validity. Data were analyzed using descriptive and comparative statist
ics (chi-square, Mann-Whitney U and Wilcoxon signed ranks tests) with p = 0
.01 considered statistically significant.
Results: One to 2 weeks after LVAD implantation, patients were quite satisf
ied with their lives, experienced moderately low amounts of stress, coped w
ell, and perceived themselves as having good health and QOL, low symptom di
stress, and moderately low functional disability. Patients reported signifi
cantly better QOL, more satisfaction with health and functioning, and were
significantly less distressed by symptoms from immediately pre-operatively
to post-operatively. However, patients reported significantly more self-car
e disability and more dissatisfaction with socioeconomic areas of life from
before to immediately after surgery. Psychological distress was low and di
d not change with time.
Conclusion: Given that QOL improved from before to after LVAD implantation,
our findings provide a springboard for investigation of the impact of LVAD
s on long-term QOL outcomes.
