Under-detection of frailty syndrome or sarcopenia can result in significant mortality and morbidity among elderly patients, especially in old-age mental health settings. Therefore, it is crucial to ensure doctors are equipped with the competency of early identification and management of frailty syndrome. To date, there is limited information about any systematic approaches to assess and improve the knowledge, attitude, and practice of doctors about frailty syndrome. This literature review is aimed to identify the tools used to assess the knowledge of doctors about frailty syndrome and the available educational intervention to improve doctors’ knowledge.

A literature search was performed in Google Scholar, PubMed, SCOPUS, Ovid, and EMBASE using the keywords of “frailty syndrome” AND “knowledge” AND “doctors”. Data collected included the assessment tool used to understand the knowledge level and the intervention used to improve the knowledge. The inclusion criteria were: studies published in English in the last 10 years which assessed the knowledge of doctors about frailty syndrome.

There were five studies fulfilling the inclusion criteria after the title and abstract screening, two from the Americas, two from Europe, and one from Australia.

The target group of studies involved general practitioners and doctors working in the primary healthcare setting (three), orthopaedic surgeons (one), and doctors working in the trauma setting (one). Two of the studies included non-medical healthcare practitioners as their participants.

One study used qualitative semi-structured individual interviews, two used a self-report questionnaire, one combined knowledge testing and self-report questionnaire, and one study compared the clinical assessment with a validated tool.

Only one study provided an educational intervention, i.e., a single-day training course conducted by three geriatricians.

Despite a comprehensive search, there were limited studies identified on this topic. The methods used to assess doctors’ knowledge about frailty syndrome are heterogeneous and no standardised tool has been identified in the process. There is only one study using educational intervention to improve knowledge, which was found to be effective and sustainable based on the change in self-perception, i.e. Kirkpatrick Level 1 of evaluation. There is a need to develop systematic assessment approaches or tools and training modules to improve the knowledge of doctors about frailty syndrome. Nevertheless, this review is limited only to studies published in English.
