[Development of a decision aid for participative advance planning for people with dementia and their relatives]

Patients with a diagnosis of dementia face various important social and health-related decisions. Due to the progression of the disease it seems crucial that patients try to deal with these decisions early in the course of the disease to have the opportunity to make decisions autonomously. Professional support can help to plan in advance according to the wishes and possibilities in an effective and individualized manner.

The instrument was developed in a multiphase process based on advance care planning and shared decision-making. The prototype was pretested on 8 patient-relative dyads from a special outpatient department for early recognition and adapted as best as possible to their needs. Subsequently, in a pilot study the applicability of the decision aid was tested as an intervention in a further 19 patient-relative dyads with trained conversion attendants (diagnosis of Alzheimer's dementia or mixed form; mini mental state examination, MMSE (Mini-Mental-State-Test-Summenwert) >20 and <27).

The result was a written decision-making aid for people with early stage dementia and their relatives, which supports the decision-making process (health care proxy, advance directive, living and care, driving ability). The first results showed good acceptance and handling. Patients and relatives dealt with the individual topics to a high degree and found them to be highly relevant.

Despite positive feedback from the participants with respect to acceptance and applicability, there were major difficulties in recruiting. In the future, the systematic use of decision support as part of routine care could help to support the decision-making process in this patient group.
