What’s the story behind NHS staff losing their sparkle?

What’s the story behind NHS staff losing their sparkle? Having recently joined the Health Foundation after a career trying to turn evidence into guidance at NICE, whenever I read a research output, I find my first question is still, ‘What recommendations can be derived from this research?’. Developing evidence-based guidance also taught me that there is very rarely a straightforward answer to the question of ‘what’: often ‘what’, and indeed ‘how’, can’t be answered without considering ‘why’.
