Advance directives in German memory clinics.

Area of Science:

• Medical Ethics
• Neurology
• Public Health

Background:

• Informed consent is a fundamental right in medical treatment.
• Impaired decision-making capacity, common in conditions like dementia, necessitates mechanisms to uphold patient autonomy.
• Advance directives serve as legally valid tools to preserve autonomy when capacity is compromised.

Purpose of the Study:

• To determine the prevalence of advance directives among patients attending German memory clinics.
• To identify predictors associated with the presence of advance directives.
• To assess adherence to informed consent standards in the creation of these directives.

Main Methods:

• An observational, cross-sectional study design was employed.
• Data were collected from 289 outpatients at German memory clinics.
• Statistical analyses included descriptive statistics and multivariable logistic regression.

Main Results:

• Age was identified as the most significant predictor for having an advance directive.
• The creation of advance directives was more frequently linked to specific life events or experiences than to inherent personal characteristics.
• Patient characteristics such as gender, education, cognitive status, health status, and health literacy were also analyzed for their influence.

Conclusions:

• Advance directives are vital for patients with cognitive impairments to ensure their autonomy is respected.
• Healthcare providers should encourage and facilitate the creation of advance directives, particularly for older patients and those experiencing significant life events.
• Further research could explore specific event-based triggers and improve compliance with informed consent standards in directive creation.
