Developing a programme theory of implementing patient-reported outcome measures for older people living with severe frailty: a mixed methods study using the consolidated framework for implementation research

By utilising the CFIR, the study highlights the complexities and variabilities of using PROMs with OPWSF. Future research should focus on adapting and validating existing PROMs to ensure they are fit for purpose with this population, with the involvement of older people with frailty and unpaid carers. Providers should extend support and training for professionals in the use and value of PROMs and psychosocial-spiritual care.
