Impact of spirituality and religiousness on outcomes in patients with ALS.

The Project of Death in America Study at Columbia Presbyterian Medical Center enrolled 121 patients with ALS from 1996 through 1997, 46 of whom participated in a study assessing the effects of religiousness and spirituality (attachment to life, mental health, support group, health care proxy, and attitudes toward death) on outcomes (technology and death). Spirituality or religion influenced use of percutaneous endoscopic gastrostomy, noninvasive assisted ventilation, tracheotomy, and attitudes toward the dying process.
