Groups2
Group 2 names the comparator: usual care.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Information | Patients and proxies in assisted living centers randomized to the information arm will receive a letter from their clinician with a link to an educational video describing the goals of care and how specific treatment decisions align with these goals. Patients and proxies will also continue to receive usual care advance care planning conversations.~Advance Care Planning Video: Clinical assistants determine who is the correct person to receive the informational materials. If the patient is the correct recipient, clinicians will send the informational materials to the patient at the assisted living center. If the proxy is the correct recipient, the clinical assistant will determine whether or not the proxy is using the existing online portal. If the proxy is using the portal, the informational materials will be sent electronically. If the proxy does not access the portal, the informational materials will be sent to their residences. | 23 | 770 | OG001 |
| Group 2 | Usual Care | Patients and proxies in assisted living centers randomized to the usual care arm have advance care planning discussions with a clinician at admission, annually, and sometimes with a hospitalization or other change in condition. There is no standardized decision- or conversation-support tools used to have these discussions. | 11 | 743 | OG000 |
