Patient and public involvement and engagement (PPIE) has evolved to become widely established practice in social care, health and public health research in the UK. The COVID-19 pandemic has caused rapid change in practice in PPIE, notably in moving from face-to-face meetings to virtual ones. This has opened a space for reflecting on established PPIE practice, but there is a risk this is conducted too narrowly, such as only weighing our preferences and the relative pros and cons with regard to in-person versus virtual meetings. The pandemic has also demonstrated the wide inequalities in society, and hence, we argue that an inequalities lens ought to guide a deeper and wider reflection on PPIE practice. We do not seek to criticize practice pre- or during the pandemic, but to encourage using the inequalities lens as a means of encouraging debate and focusing energy on a more rigorous review of PPIE practice to widen involvement in social care, health and public health research.
