Systematic implementation of an advance directive program in nursing homes: a randomized controlled trial (see comments)

摘要

CONTEXT: Although advance directives are commonly used in the community, little is known about the effects of their systematic implementation. OBJECTIVES: To examine the effect of systematically implementing an advance directive in nursing homes on patient and family satisfaction with involvement in decision making and on health care costs. DESIGN: Randomized controlled trial conducted June 1, 1994, to August 31, 1998. SETTING AND PARTICIPANTS: A total of 1292 residents in 6 Ontario nursing homes with more than 100 residents each. INTERVENTION: The Let Me Decide advance directive program included educating staff in local hospitals and nursing homes, residents, and families about advance directives and offering competent residents or next-of-kin of mentally incompetent residents an advance directive that provided a range of health care choices for life-threatening illness, cardiac arrest, and nutrition. The 6 nursing homes were pair-matched on key characteristics, and 1 home per pair was randomized to take part in the program. Control nursing homes continued with prior policies concerning advance directives. MAIN OUTCOME MEASURES: Residents' and families' satisfaction with health care and health care services utilization over 18 months, compared between intervention and control nursing homes. RESULTS: Of 527 participating residents in intervention nursing homes, 49% of competent residents and 78% of families of incompetent residents completed advance directives. Satisfaction was not significantly different in intervention and control nursing homes. The mean difference (scale, 1-7) between intervention and control homes was -0.16 (95 % confidence interval [CI], -0.41 to 0.10) for competent residents and 0.07 (95% CI, -0.08 to 0.23) for families of incompetent residents. Intervention nursing homes reported fewer hospitalizations per resident (mean, 0.27 vs 0.48; P = .001) and less resource use (average total cost per patient, Can
