After completing a fellowship in observation medicine with Dr. Graff in Connecticut, USA, Dr. Mahadevan, started the first observation unit (OU) at National University Hospital in Singapore in 2004. After two additional Singapore physicians completed a fellowship with Dr. Mace in Cleveland, Ohio, USA in 2006-2007, additional OUs were started. Currently, there are seven OUs in Singapore. In 2016, the OU became a “hybrid” unit with the admission of pediatric patients above 6 years of age. During the COVID-19 pandemic in early 2020, the OU was converted into a pandemic isolation ward for suspected COVID + patients in order to increase ED capacity. For reimbursement there needed to be the approval from the government that observation patients could use their medical savings called Medisave). Various protocols have been developed including a protocol on the management of primary spontaneous pneumothorax.. One merit of observation medicine has been a reduction in overall length of stay in the hospital, thus freeing up more inpatient beds for the needy and sicker patients.
