Validation of the Screening Instrument: PRISMA-7 for Frailty Among Elderly Hospitalized Danes

The questionnaire PRISMA-7 was originally developed to assess frailty in community dwelling adults. The questionnaire was translated into the Danish language. This instrument was used to screen for frailty among elderly patients (75+) sent home from Nykøbing Falster Hospital after a hospital admission during the period 31. May 2017 until December 31st, 2018. PRISMA results were used to categorize each individula as frail or non-frail. The register of PRISMA results was merged with national registers on use of health serviced in order to investigate if increasing PRISMA score was associated with increasing use of health services.
