Understanding the impact of radiotherapy related insufficiency fractures and exploring satisfaction with two existing patient reported outcome measures: A qualitative interview study

INTRODUCTION: Radiotherapy related insufficiency fractures (RRIFs) occur in approximately 10–15% of cancer survivors who underwent pelvic radiotherapy. Little research has been conducted to explore the impact of RRIFs on quality of life (QOL). Patient reported outcome measures (PROMs) are often used in oncology to measure side effects and QOL. The study aims to understand the influence of RRIF on QOL and to discover whether available PROMs address their needs. MATERIALS AND METHODS: Twenty-five patients randomly selected from a Tertiary Oncology Centre bone health clinic database of patients referred with RRIFs were approached. Interested patients were sent two existing PROMs and a patient information sheet. Eleven patients agreed to take part in a semi-structured interview to explore their experiences and their opinion on the existing PROMs. Telephone interviews were conducted. Interviews were audio recorded, transcribed, and analysed using thematic analysis. RESULTS: Four themes were identified: 1) Route to diagnosis, 2) management of RRIFs and 3) resilience all had an impact on 4) QOL. Additionally, participants discussed PROMs and how they might be integrated into clinical practice. The data highlights the wide ranging QOL impacts experienced and highlights potential areas for improvement in terms of diagnosis and management pathways. DISCUSSION: The impact of RRIFs on QOL is considerable. Participants highlighted key areas for improvement including the provision of more information, more access to support and improved management pathways. Participants also highlighted the potential benefits of PROMs but suggested existing measures could be improved.
