Advance Directives in Austrian Intensive Care Units: An Analysis of Prevalence and Barriers

Purpose: To investigate the prevalence of advance directives, healthcare proxies, and legal representatives in Austrian intensive care units (ICUs), and to explore barriers faced by adults engaged in the contemplation and documentation phase of the advance care planning process.

Methods: Two studies were conducted: (1) A 4-week multicenter study covering seven Austrian ICUs. A retrospective chart review of 475 patients who presented to the ICUs between 1 January 2019 and 31 January 2019 was conducted. (2) An interview and focus group study with 12 semi-structured expert interviews and three focus groups with 21 adults was performed to gain insights into potential barriers faced by Austrian adults planning medical decisions in advance.

Results: Of the 475 ICU patients, 3 (0.6%) had an advance directive, 4 (0.8%) had a healthcare proxy, and 7 (1.5%) had a legal guardian. Despite the low prevalence rates, patients and relatives reacted positively to the question of whether they had an advance directive. Patients older than 55 years and patients with children reacted significantly more positively than younger patients and patients without children. The interviews and focus groups revealed important barriers that prevent adults in Austria from considering planning in advance for potentially critical health states.

Conclusion: The studies show low prevalence rates of healthcare documents in Austrian ICUs. However, when patients were asked about an advance directive, reactions indicated positive attitudes. The gap between positive attitudes and actual document completion can be explained by multiple barriers that exist for adults in Austria when it comes to planning for potential future incapacity.
