Agreement With Consensus Statements on End-of-Life Care: A Description of Variability at the Level of the Provider, Hospital, and Country.

Objectives: To develop an enhanced understanding of factors that influence providers' views about end-of-life care, we examined the contributions of provider, hospital, and country to variability in agreement with consensus statements about end-of-life care. Design and Setting: Data were drawn from a survey of providers' views on principles of end-of-life care obtained during the consensus process for the Worldwide End-of-Life Practice for Patients in ICUs study. Subjects: Participants in Worldwide End-of-Life Practice for Patients in ICUs included physicians, nurses, and other providers. Our sample included 1,068 providers from 178 hospitals and 31 countries. Interventions: None. Measurements and Main Results: We examined views on cardiopulmonary resuscitation and withholding/withdrawing life-sustaining treatments, using a three-level linear mixed model of responses from providers within hospitals within countries. Of 1,068 providers from 178 hospitals and 31 countries, 1% strongly disagreed, 7% disagreed, 11% were neutral, 44% agreed, and 36% strongly agreed with declining to offer cardiopulmonary resuscitation when not indicated. Of the total variability in those responses, 98%, 0%, and 2% were explained by differences among providers, hospitals, and countries, respectively. After accounting for provider characteristics and hospital size, the variance partition was similar. Results were similar for withholding/withdrawing life-sustaining treatments. Conclusions: Variability in agreement with consensus statements about end-of-life care is related primarily to differences among providers. Acknowledging the primary source of variability may facilitate efforts to achieve consensus and improve decision-making for critically ill patients and their family members at the end of life.
