In November 2013 she was interviewed about the demand for safe staffing levels in NHS hospitals and told ITV Daybreak: "The most important thing to do is to use evidence to determine what the staffing levels should be. "It's actually quite dangerous to to [sic] suggest that there must be a particular minimum and what we really need to do is to look at the needs of the patients on a particular ward or service and that will vary.".
In December 2013 she was involved in the launch of the £100 million Nursing Technology Fund and said “Technology is a tool that, if embraced and used in the right way, allows healthcare professionals to work differently and more effectively so they can focus on what they do best – providing compassionate, high quality care for patients."
She was said by the Health Service Journal to be the 36th most powerful person in the English NHS in December 2013. As of 2015, Cummings was paid a salary of between £165,000 and £169,999 by NHS England, making her one of the 328 most highly paid people in the British public sector at that time.
