Perspectives of healthcare professionals on frailty assessment among older patients with colorectal cancer: A qualitative study

Purpose: Exploring the perspectives of healthcare professionals (HCPs) working at the outpatient clinic on the value and practice of standardized frailty assessment in older adults with colorectal cancer (CRC). In current practice, frailty assessment comprises initial frailty screening using the G8 measurement, followed by a comprehensive geriatric assessment (CGA) to further evaluate frailty detected during screening.

Methods: This is a qualitative study involving semi-structured interviews with 17 HCPs, conducted from February to July 2023. Physicians specializing in oncology, surgery, gastroenterology, and geriatrics were asked to participate as well as nurses and nurse practitioners at the outpatient clinic of a large teaching hospital involved in frailty assessment of patients with CRC.

Results: Two main themes emerged: 1) the perceived value of the G8 measurement for frailty screening and 2) the perceived value of the CGA. The moment, content, and outcome of the G8 and CGA were discussed. Other issues discussed were the complexity of frailty appreciation and collaboration between HCPs. The integration of perspectives proved important to the overall added value of frailty assessment. The CGA is considered most beneficial in patients with suspected cognitive impairment or if there is uncertainty about the degree of frailty or about the optimal treatment.

Conclusion: We conclude that the G8 is not an appropriate screening instrument for this patient population. CGA adds value in a specific subset of patients if it is conducted before treatment decisions are made and integrated into an efficient, multidisciplinary pathway, focusing on collaborative decision-making, including with the patient.
