“I am passionate about delivering joined-up care. I believe qualitative research and anecdotal evidence can inform/enhance quantitative research, and both are valid channels for feedback. The NHS asks, “How are we doing” I think we should also be finding ways to ask, “What do you need?” Collaboratively we can find ways to meaningfully engage and achieve more equitable outcomes, better person-centred care and to translate that engagement into exemplary practice.”
