Impact of advance directive videotape on patient comprehension and treatment preferences.

OBJECTIVE

To examine the effects of an advance directive videotape on patient comprehension of advance directive concepts and preferences for resuscitation.

DESIGN

Pilot study, randomized cohort trial.

SETTING

Extended Care and Rehabilitation Center, Veterans Affairs Medical Center, Durham, NC.

PARTICIPANTS

Thirty-six residents of the center; mean age, 69 years.

INTERVENTIONS

Sixteen subjects observed an advance directive videotape, and 20 subjects observed a health-relative videotape. All subjects received written material and counseling on advance directives.

MEASUREMENT

Structured interviews were conducted at three time points relative to the educational program (pretest, posttest, delayed posttest), measuring comprehension of two advance directive concepts (living will and cardiopulmonary resuscitation) and resuscitation preferences based on hypothetical clinical vignettes. Mean comprehension and mean resuscitation preference scores were derived for each time point.

RESULTS

The mean comprehension score improved an average of 1.6 points for all subjects from pretest to delayed posttest (P < .001); however, score changes were not significantly different between the two video groups (P = .39). Mean resuscitation preference scores were stable over time, and there were no significant score differences between the two video groups.

CONCLUSION

The advance directive videotape did not significantly affect resuscitation preferences or comprehension of selected advance directive concepts.
