The College of Public Health and Occupational Physicians (CPHOP) was formed on 1 February 2013 as a non-independent college of the Academy of Medicine, Singapore. The first steps towards the formation of the College started on 15 May 1980, when 12 members of the Academy wrote to the Council proposing the formation of a Chapter of Community Medicine. During the Annual General Meeting of the Academy on 29 November 1980, it was moved that a new Chapter called Chapter of Community and Occupational Medicine, be formed. The inaugural meeting of the Chapter was held on 21 January 1981.
Over the years, the name of the Chapter of Community and Occupational Medicine underwent several changes to reflect the changing terminology of the disciplines. It was re-named the Chapter of Community and Occupational Physicians in January 1987, and subsequently the Chapter of Public Health and Occupational Physicians in June 1999. Following the accreditation of aviation medicine as a subspecialty in May 2014, Academy Council approved the admission of aviation medicine physicians under the College on 3 November 2014.
The College provides professional leadership and continuing education in public health, occupational medicine and aviation medicine. It also provides recommendations to the Academy of Medicine, Singapore, on specialist qualification and training, and Fellows of the College serve on national specialist training committees and academic programme committees of the three specialties. The College collaborates with Saw Swee Hock School of Public Health, National University of Singapore, in organising continuing medical education programmes. The College also supports the training of residents of the Preventive Medicine Residency, and senior residents of the Public Health, Occupational Medicine and Aviation Medicine Senior Residency programmes.
