Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a pilot study that aims to create a dementia-specific intervention of advance care planning (ACP) and test its feasibility and acceptance with min 20 max 30 patient-relative dyads.

The intervention is adapted from the Multiprofessional advance care planning and shared decision-making for end of life care (MAPS) Trials 1 and 2 made at the Zurich University Hospital.

The study design is longitudinal (historic): all the dyads will be asked to go through the process (4 visits, see 9.3 Procedures at each visit).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study background and aims:

Advance care planning (ACP) is a structured communication process between an individual, his family, and his healthcare agent (if existing), facilitated by a healthcare provider. The aim is to identify the personal values of the individual, reflect on the meanings and consequences of anticipated illness scenarios, define goals and preferences of care for these situations, issue appropriate documents and legal instruments that will help direct future healthcare decisions, and review these steps at adequate intervals. ACP emphasizes communication in anticipation of a future deterioration of a person's health. Even though dementia entails the loss of decision-making capacity, advance care planning is yet to become widespread. This study aims to close the gap and create a dementia-specific ACP intervention that:

* Support patient autonomy through advance care planning
* Improve participants' satisfaction and perceived control;
* Increase planning decisions and surrogate's knowledge of patients' preferences and values.

Procedure and measure:

Pre-intervention assessment (Visit 1):

If the patient and her/his relative have both consented to the study, the PI will ask the patient and her/his relative to fil out psychometric scales: Hospital anxiety and depression scale (HADS), Decisional conflict scale, Personal autonomy scale and Zarit Burden Inventory. Then, the PI will realize a semi-structured interview on patient's val-ues and treatment preferences and caregiver's knowledge of patient's preferences and care planning decisions that have already been made. Participants will also be asked to hand out a copy of any pre-existing advance directives or other advance care planning document.

Intervention (Visit 2):

In the intervention this first conversation (45-90 min) with a specifically trained ACP facilitator aims to explain the goal and content of ACP and prompt the patient to reflect upon his/her values and preferences for healthcare and discuss them with his/her caregiver. In addition, the written decision aids will be explained and provided to the patient/caregiver to be read at home. At the end of the meeting, the facilitator will ask to set up the second meeting.

Intervention (Visit 3):

The second conversation of the ACP facilitator with the patient and her/his caregiver aims to help the patient to specify her/his preferences and trans-late them into actionable documentation. The discussions also aim to empower the caregiver to make sure that these decisions are respected.

Post-intervention assessment (Visit 4):

The PI will start the meeting with a semi-structured interview (30-45 min) on the dyad's subjective experience with the intervention, positive and nega-tive effects, and challenges and suggestions to modify the intervention. Participants will also be asked to hand over copies of ACP documents produced during the intervention or after it in order to be analysed. After the interview, the PI will ask the patient and her/his relative to fill in psychometric scales: Hospital anxiety and depression scale (HADS), Decisional conflict scale, Personal autonomy scale and Zarit Burden Inventory.
