International Nurses Day is celebrated annually on May 12th to mark Florence Nightingale's birthday. The 2014 theme is "Nurses: A Force for Change – A vital resource for health". Nursing is the largest healthcare profession and nurses play a key role in healthcare delivery and achieving health goals. National nursing associations educate and support nurses to deliver better care, and work with governments and organizations to strengthen healthcare systems. The International Council of Nurses celebrates this day to raise awareness of nursing's contributions to healthcare innovation.
