The CFS is introduced and tested as part of a quality-improvement process regarding elderly people within the Emergency departments (EDs) of Region Östergötland (Östergötland County) in Sweden. CFS is a 9-point scale developed within the Canadian Study of Health and Aging. It comprises of a pictograms and a clinical description to help assign scores ranging from very fit to terminally ill. CFS enables clinicians to rapidly stratify the degree of frailty in the elderly with the help of questions and clinical assessment. However, since the assessment is judgement based, it is important that the inter-rater reliability is satisfactory. This study is part of a larger project where all eligible patients who visit the ED (24/7) for a period of four weeks will be enrolled and then subsequently assessed with CFS by one of their responsible health-care professionals (i.e. physician, registered nurse or nurse assistant). For this study, each professional on the team will individually assess each patient. First, a clinical judgement is performed (frail/not frail) without any instrument, and then the patient is assessed by using the CFS. This will take place during work shifts when someone from the research team is present and can arrange the assessments, as well as ensure that they are conducted independently. These work shifts will be selected using the online application Research Randomizer, to randomly include all hours of the day as well as eligible health-care professionals. The research-team member will collect the assigned CFS-scores and information on the age, gender, profession, position (emergency physician or intern/resident from other specialities) and the number of years in the profession of each assessor. Informed consent will be obtained from all health-care professionals who participate. No data that can identify any patient will be collected. Sample size is determined to be 100 patients, which would be more than sufficient with a power of 90% and ? 0,05.
