Didier Pittet (born 20 March 1957 in Geneva, Switzerland) is the director of the Infection Control Programme and WHO Collaborating Centre on Patient Safety, University Hospital of Geneva, Geneva, Switzerland. Since 2005, Pittet is also the External Lead of the World Health Organization (WHO) Global Patient Safety Challenge "Clean Care is Safer Care" and African Partnerships for Patient Safety.

In the 2007 New Year Honours List, Didier Pittet was awarded the Honorary Commander of the Order of the British Empire[1] (CBE) in recognition of his services related to the prevention of healthcare-associated infections in the UK.

Career

Pittet graduated in 1976 from the Collège Calvin secondary school in Geneva, Switzerland. Following a Diploma in Tropical Medicine and Community Health at the University of Geneva Faculty of Medicine, he graduated as M.D. in 1983 from the same institution, and received a master's degree (MS) in Epidemiology and Public Health from the University of Iowa,[2][3] Iowa City, US, in 1992. Pittet began his career as an infectious diseases expert with a special interest in the intensive care setting and device-associated and yeast infections, but this rapidly expanded to include research in overall hospital epidemiology and infection prevention and control. In 1992, he was appointed as Director of the Infection Control Programme at the University Hospital of Geneva and named Professor of Medicine in 2000 by the University of Geneva Faculty of Medicine.

Pittet is Visiting Professor, Division of Investigative Science and School of Medicine, Imperial College London, London, UK;[4] Honorary Professor, 1st Medical School of the Fu, Shanghai, China;[5] Honorary Professor, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hong Kong, SAR, China.[6] Since 2002, Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) Planning Committee member Since 2011, Co-Chair, 1st International Conference on Prevention and Infection Control (ICPIC)

Landmark research

Initial observation studies in Geneva by Pittet's team showed a low compliance with basic hand hygiene practices and a lack of awareness by healthcare workers that the main cause of cross-transmission of microorganisms is by hands.[7] Time constraint was identified as the major determinant for poor compliance.[8] The challenge was to facilitate hand hygiene for staff and to find an innovative idea to do so. Under Pittet's leadership, the team investigated concepts from the social sciences to help understand the determinants driving healthcare worker behaviour, which led to the creation of a multimodal strategy based on education, recognition of opportunities for hand hygiene, and feedback on performance where the key component was the introduction of alcohol-based hand rub at the point of care to replace handwashing at the sink ("system change"), thus bypassing the time constraint of the latter method.[9]

"The Geneva Hand Hygiene Model": a breakthrough intervention

The first multimodal intervention ran from 1995 to 2000 at the University of Geneva Hospitals with a spectacular decrease of almost 50% in hospital-associated infections and methicillin-resistant ''Staphylococcus aureus'' transmission in parallel with a sustained improvement in compliance with hand hygiene. The methodology and results were published in The Lancet in 2000 and the strategy became known in as "The Geneva Hand Hygiene Model".[9] During 1995–1997, Pittet had applied the same multimodal concept to a prevention strategy targeted at vascular access care and showed that it can decrease these infections and substantially impact on the overall incidence of all intensive care unit-acquired infections.[10] Similarly, interventions to reduce urinary tract infections were successfully applied.[11] Pittet's team also proved the cost-effectiveness of their interventions and long-term sustainability.[12][13] Pittet's vision is that to advance infection prevention and control strategies, it is essential to seek insight and innovation through other specialty fields, such as anthropology or sociology, or even engineering, computer science, mathematical modelling, and systems thinking.

Going global

In 2004, Pittet was approached by the WHO World Alliance of Patient Safety to lead the First Global Patient Safety Challenge under the banner "Clean Care is Safer Care".[14][15][16] The mandate was to galvanise global commitment to tackle health-care associated infection, which had been identified as a significant area of risk for patients in all United Nations Member States.[17] Hand hygiene was to be the cornerstone of the Challenge. As co-author of the United States Centers for Disease Control and Prevention (CDC) Guidelines for Hand Hygiene,[18] Pittet proposed that WHO Guidelines for Hand Hygiene in Health Care be developed under his leadership in consultation with other international experts. The final version of the Guidelines[19] was published in 2009. In 2008, the infection control programme of the University of Geneva Hospitals and Faculty of Medicine was designated as the first WHO Collaborating Centre for Patient Safety (Infection Control and Improving Practices) in Europe.

The "Geneva Hand Hygiene Model" was used as the basis for the recommended implementation strategy[20] for the global promotion of hand hygiene. As of December 2011, "Clean Care is Safer Care" has been endorsed by ministers of health in over 120 countries worldwide―representing a coverage of more than 90% of the world population. Forty-two countries/networks[21] have already started hand hygiene initiatives using the proposed strategy. Alcohol-based hand rub is promoted actively as the new standard of care, including in resource-poor countries.[22][23] Pittet's team developed the "Five Moments" concept to explain to healthcare workers the critical moments when hand hygiene must be carried out[24] and this model is currently used worldwide. Save Lives: Clean Your Hands is the Challenge's annual campaign with almost 15,000 hospitals registered from more than 150 countries at the end of December 2011.
