Ethics approval and consent to participate
: The study was conducted in accordance with the ethical standards set forth in the Helsinki Declaration (1983). All patients admitted to the geriatric acute care ward of the university-affiliated hospital or their legal guardian, when appropriate, were informed that their medical information could be used for research purposes. The obtained informed consent was verbal. The ethics committee approved this informed consent, as it is generically obtained for all patients admitted to the geriatric ward of St. Mary’s hospital and because data collection was retrospective. In case of refusal, patients informed the physician in charge of the geriatric acute care ward verbally and this information was noted in their medical chart. There was no refusal to use medical information for research purposes in the participants recruited for this study. The ethics committee of St. Mary’s Hospital (Montreal, Quebec, Canada) approved the study.
