Our previous research found that while many organisations across Canada and in many other countries, including England, Sweden, Australia and New Zealand, measure PCC using patient experience measures, few organisations use quality indicators to monitor and evaluate PCC. 22 Furthermore, in a 2019 scoping review of the literature, we also found scarce evidence on the implementation of PC-QIs and evaluation of their use, highlighting a significant gap in the literature. 31 However, some studies have explored the factors that influence the implementation and use of quality indicators, although not specifically focused on measuring PCC. Our findings are consistent with previous research on quality indicator implementation in various care settings and studies on the implementation of PREMs and PROMs. 10-12 32-34 Challenges associated with knowledge, skills (need for training), time constraints and motivation around measurement have been widely reported. Important facilitators to support quality indicator implementation that have also been reported include the need for administrative support for clinicians, 10 the importance of electronic **data** systems, 12 32 and alignment with national and regional priorities, 11 the need to integrate measurement within established workflows to minimise patient care disruptions, as well as the uncertainty around the benefits of using patient-reported data. 32 Our findings also suggest inequitable uptake of personcentred QI, where organisations that are least resourced may also be in most need of improved quality of care that is person-centred. This includes organisations in Canada's Northern Territories, which are home to a larger proportion of Indigenous communities, relative to other areas of Canada, as well as rural primary care clinics, where people experience challenges with remote access to services. Rolnitsky et al conducted a 2018 mapping review of the literature to measure the representation of vulnerable populations in QI studies. 35 They found that while one-third of QI research is focused on vulnerable populations, some populations are under-represented (less than 2%), including rural residents, the poor, visible minorities, the terminally ill, adolescents and prisoners. 35 Moreover, in Canada, as well as Australia, New Zealand and the USA, inequities related to the quality of care for Indigenous people are well documented. 36 These gaps that have been identified in research, including this study, suggest a need for increased attention to more equitable implementation of QI, especially focused on promoting PCC.
