Gender-based differences in decision making, quality of life and survival among patients undergoing left ventricular assist device evaluation.

Abstract

Women are less likely to receive left ventricular assist devices and are more likely to experience poor outcomes. However, how gender impacts LVAD decision-making regarding LVAD implantation and the effects of that decision remains unknown. We performed a sub-group analysis from the stepped-wedge DECIDE-LVAD trial, which tested a decision-support intervention for patients considering LVAD therapy. Excluding 9 patients who withdrew from assessments, of the 239 patients analyzed, 203 (85%) were men and 36 (15%) were women. More men received LVADs (70%) than women (61%) and more men were alive at 6 months compared to women, both among those who received LVADs (87% vs 82%) and those who did not (74% vs 50%) (p = 0.002). Compared to men, women were more likely to have decision regret, depressive symptoms and perceived stress at baseline but not at follow-up. At 6-month follow-up, men experience improvements in decisional conflict, acceptance of illness, struggle with illness, and perceived stress-none of those improvements were noted amongst women. Compared to men who received LVADs, women receiving LVADs had worse decision regret and depressive symptoms at baseline and worse acceptance of illness and perceived stress at six months. Men who received LVADs experienced improvement in decisional conflict and perceived stress, while women did not experience these improvements. Both men and women who received LVADs experienced improvement in depressive symptoms. Quality of life as assessed by EuroQol visual analog scale improved for both men and women who received LVADs but not for those who did not receive LVADs; no gender differences in quality of life were noted. Women require greater decisional support at time of decision to undergo LVAD implantation and subsequently might benefit from more intensive psychosocial support.
