The idea of forming a society as a social network for critical care nurses was first conceived in 1974 by nurses who were working in the Coronary Care and Renal Units. That idea resulted in the birth of an ICU Club the same year. Monthly meeting were held to discuss work issues. That was usually followed by a high tea at coffee house or picnic.
In 1986, Miss V. Mudeliar a former tutor for the Intensive Nursing Care Course inaugurated the Critical Care Nurses Chapter at Mount Elizabeth Hospital. Miss Mudeliar was unanimously elected as its first Chairman. Mdm Tang Ah Moy was the Vice Chairman and Miss Lim Ee Lee the Secretary.
