Nurses' perceptions of medical procedures and nursing practices for older patients with non-cancer long-term illness and do-not-attempt-resuscitation orders: A vignette study.

Nurses' perception on cardiopulmonary resuscitation, defibrillation, blood tests and intravenous nutrition showed statistically significant and minimally important declines after the DNAR order compared with before for all three vignettes (p < .001). DNAR orders can influence nurses' perceptions of clinical practices for non-cancer older patients with chronic heart failure.
