Assessing the Appropriateness of Frailty Screening in the Australian General Practice Context: Ethics, Accuracy, Feasibility and Acceptability

Rachel Ambagtsheer
Frailty exposes older people to significant negative impacts on health and well being. Evidence suggesting that frailty is reversible has led to calls for greater proactivity on its identification and treatment within general practice, although implementation research is lacking in many countries, including Australia. This study aimed to explore the appropriateness of introducing frailty screening within Australian general practice, with specific objectives addressing the 1) ethics 2) accuracy

The first, a narrative review exploring the principles of ethical screening, suggested that the most appropriate current application of frailty screening within general practice is for case-finding of vulnerable older people. Next, a systematic review of self-reported frailty screening instruments demonstrated insufficient validation evidence for many, providing justification for the third sub-study (n=243), in which the DTA of several instruments was assessed against the Frailty Phenotype (FP) and Frailty Index (FI). Several instruments (Kihon Checklist (KC), Reported Edmonton Frail Scale (REFS) and PRISMA-7) showed promise for broader implementation. In a fourth sub-study, the DTA and feasibility of an electronic Frailty Index (eFI) was assessed (n=60). Although sufficiently accurate, the findings suggest that an eFI is currently unviable for Australian general practice. The fifth sub-study explored attitudes of Australian general practitioners (GPs) towards frailty and frailty screening. GPs largely saw frailty as a cycle of worsening decline, with few having attempting intervention, but most were open to screening given sufficient support. The sixth sub-study assessed the feasibility and acceptability of several instruments in practice. Of these, the PRISMA-7 performed best. The two self administered instruments (KC and REFS) returned higher rates of non completion than the nurse-administered instruments. [...]
