Frances Mair and I have an Editorial in this week’s British Medical Journal that sets out some of the key problems around Burden of Treatment and multi-morbidity. That the BMJ should commission this editorial from us shows that the idea of Burden of Treatment is getting traction across the healthcare economy. And why shouldn’t it? The bug issue here is patient and carer workload – something that we know much less about than we should. The editorial comes hot on the heels of an important meeting sponsored jointly by the National Institute of Health Research and the Royal College of General Practitioners that sought to develop a strong research agenda on multi-morbidity. The key message that I took away from that meeting was that there was a real risk of turning multi-morbidity into a kind of new disease in itself – in the way that we often now hear chronic illness and long-term conditions spoken about in a quite undifferentiated way. In fact, the big problems here are at a system level, and they’re the problems that Frances and I discuss in our editorial. I was a plenary speaker at the RCGP NIHR Multimorbidity meeting and I’ve embedded my powerpoint presentation below.
