Museum Prescription by a Physician for a Visit to the MBAM

Quality of life will be assessed using the EuroQol-5D (EQ-5D).

EuroQol-5D is composed of two parts:

• a five-question questionnaire with a score per question ranging from 1 (no problem) to 5 (severe problem), so that the sum ranged from 0 (no problem) to 25 (severe problem).
• a visual analogue scale on participants' perceived health. This scale is numbered from 0 (i.e., the worst health the participant can imagine) to 100 (i.e., the best health the participant can imagine).

This questionnaire will be completed online on the CRIUGM web platform using an electronic device.

Well-being will be assessed using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS).

The WEMWBS is a validated questionnaire composed by a 14-item positively worded scale and five response categories. It covers most aspects of positive mental health (positive thoughts and feelings).

This questionnaire will be completed online on the CRIUGM web platform using an electronic device.

Physical health status will be assessed using the CRIUGM Self-AdMinistered questionnaire (CESAM).

The CESAM has been previously developed and validated.

It is composed of 20 items exploring several domains:

• weight loss and its extent;
• polypharmacy defined by a number of therapeutic classes taken on a daily basis ≥ 5;
• vision, hearing, and memory problems;
• use of home support;
• 6-item activities of daily living scale, 4-item instrumental activities of daily living scale;
• mood assessed
• regular physical activity defined as at least 1 hour per week in the past month;
• and history of falls in the past 12 months.

The CESAM provides two complementary scores:

• An overall frailty score ranging from 0 to 18
• A four-stage categorization of frailty

This questionnaire will be completed online on the CRIUGM web platform using an electronic device.

Social isolation will be assessed using the 11-item Duke Social Support Index (DSSI).

This index includes two subscales:

• social interaction (i.e., frequency of interactions)
• subjective support (i.e., satisfaction with emotional support provided).

The DSSI score ranges from 11 to 33, with higher scores indicating higher levels of social inclusion. Scores for the 11 items are combined and categorized as low (score ≤26), high (score 27-29), and very high (score 30-33). We will use the mean score of the 11-item DSSI and its breakdown into three categories as the primary outcome.

This questionnaire will be completed online on the CRIUGM web platform using an electronic device.

Researchers will also study the prescribing context. A document will be filled by primary care physicians to give additional informations on the prescribing context such as the date of the prescription and the reason of the prescription.

A short questionnaire will be given to participants to the intervention at the end of the visit to the museum. This questionnaire will give additionnal information on the satisfaction from the visit and whether the visit was made alone or accompanied.
