Flowchart of patient recruitment. ^* Of 31 patients who were born between 1 January 1951 and 30 June 1951, EMR data could not be screened by the frailty-screening software. For the pseudonymisation of personal data, birth dates were set to 1 July of the patients’ birth year. Consequently, these 31 patients were not considered as ≥ 60 years of age.
