Plain English Summary
Background and study aims
Delirium among patients hospitalized in cardiology is widespread but challenging to identify. Family members are an untapped resource for detecting delirium as they know the patients’ baseline level of cognitive function, which is key in detecting subtle cognitive changes occurring in delirium. The family confusion assessment method (FAM-CAM), is a tool that could support family involvement in the detection of delirium. However, the French version of the FAM-CAM has not yet been validated, which limits its use. The aim of this study is to translate, culturally adapt and validate the French version of the FAM-CAM among a cardiology population.
Who can participate?
Hospitalized patients and their family caregivers (spouse, child, other family, friend), aged 18 or older
What does the study involve?
For participants this study involves completing the translated FAM-CAM (an 11 item questionnaire) at the bedside of their loved one.
What are the possible benefits and risks of participating?
Participants will not derive any personal benefit from their participation in this study. However, the results that are obtained could contribute to the advancement of knowledge in this area. Aside from time spent completing the questionnaire, there are no other anticipated consequences or risks associated with participation.

Study hypothesis
The trialists performed the translation and cultural adaptation of the FAM-CAM according to the rigorous approach proposed by Sousa and Rojjanasrirat (2011). Following this, the psychometric properties of the French version of FAM-CAM were assessed among hospitalized patients in in cardiovascular care. To do so, the first aim (Aim#1) of this study was to assess the sensitivity and specificity of the French FAM-CAM by contrasting it with the reference standard (medical diagnosis according to DSM-5 criteria). The secondary aim was to assess the sensitivity and specificity of the French FAM-CAM by contrasting it with (Aim#2a) delirium defined from a set of keywords associated with delirium (encephalopathy, confusion, agitation, hallucination, somnolence, haldol [Puelle et al., 2015]) and with (Aim#2b) scores on the Confusion Assessment Method (CAM). The third aim (Aim#3) consisted of assessing the FAMCAM’s predictive value by contrasting it with the reference standard using a ROC curve. Finally, the last aim (Aim#4) was to assess the reliability of the FAM-CAM by contrasting it with the CAM.

Delirium
Intervention
The original English version of the FAM-CAM was translated and culturally adapted to French for Quebec, Canada with the method suggested by Sousa and Rojjanasrirat (2011). The process included obtaining the copyright clearance from the author for use and translation; double forward and backward translations; expert committee decision making and assessment of degree of clarity of the translated version by members of the population. Following this a validation study was performed using the French FAM-CAM. There is no follow-up planned in this study.

Eligibility
Participant inclusion criteria
1. The family caregiver had to identify as a family caregiver (spouse, child, other family, friend) of an inpatient
2. Report having regular contact before hospitalization (≥ once a week). In the literature, this frequency of interaction was considered sufficient for the family member to report the usual cognitive and functional state of the patient, a knowledge necessary to be able to identify changes (Martins et al., 2014; Steis et al., 2012)
3. Have visited the patient at the hospital at least twice
4. Have the capacity to provide informed consent
5. 18 years old or older
6. Understand and read French
7. The hospitalized patient had to have the ability to provide informed consent or have a legal representative if their cognitive functioning was altered and present a stable clinical condition, allowing the evaluation of delirium using a questionnaire such as FAMCAM
