I've been a leader of large scale change in the English National Health Servce (NHS) for more than 20 years. I led the groundbreaking "Business Process Reengineering" transformation programme at the The Leicester Royal Infirmary in the 1990s. As a result, I was asked to become a national leader of initiatives to improve patient access to NHS care. I've been involved in many NHS improvement invitiatves that have made a difference for thousands of patient. I introduced the first nationwide collaborative programmes to improve the delivery of cancer care across England in 2000. I designed the highly influential "Ten High Impact Changes for Service Improvement and Delivery" in 2004 and conceived the impactful "Productive Series" starting with "The Productive Ward" in 2007. In 2010, I was part of the team that launched a call to action, utilising social movement leadership principles, which contributed to a 51% reduction in prescribing of antipsychotic drugs to people with dementia across the country. I was also one of the initiators of NHS Change Day, in partnership with a group of young clinical and managerial leaders. NHS Change Day, 13th March 2013, was the largest ever voluntary collective action for improvement in the history of the NHS with 189,000 people pleding to take action to improve experience and outcomes for patients. In 2014, Change Day will go global.
