A randomized controlled trial of a CPR decision support video for patients admitted to the general medicine service

BACKGROUND: Patient preferences regarding cardiopulmonary resuscitation (CPR) are important, especially during hospitalization when a patient’s health is changing. Yet many patients are not adequately informed or involved in the decision-making process. OBJECTIVES: We examined the effect of an informational video about CPR on hospitalized patients’ code status choices. DESIGN: This was a prospective, randomized trial conducted at the Minneapolis Veterans Affairs Health Care System in Minnesota. PARTICIPANTS: We enrolled 119 patients, hospitalized on the general medicine service, and at least 65 years old. The majority were men (97%) with a mean age of 75. INTERVENTION: A video described code status choices: full code (CPR and intubation if required), do not resuscitate (DNR), and do not resuscitate/do not intubate (DNR/DNI). Participants were randomized to watch the video (n = 59) or usual care (n = 60). MEASUREMENTS: The primary outcome was participants’ code status preferences. Secondary outcomes included a questionnaire designed to evaluate participants’ trust in their healthcare team and knowledge and perceptions about CPR. RESULTS: Participants who viewed the video were less likely to choose full code (37%) compared to participants in the usual care group (71%) and more likely to choose DNR/DNI (56% in the video group vs. 17% in the control group) (P < 0.00001). We did not see a difference in trust in their healthcare team or knowledge and perceptions about CPR as assessed by our questionnaire. CONCLUSIONS: Hospitalized patients who watched a video about CPR and code status choices were less likely to choose full code and more likely to choose DNR/DNI.
