On 11 October 1929, Chew was born in Kuching, Raj of Sarawak. In 1930, his family moved to Singapore, and lived along Jalan Tanah Puteh, located in Bedok. Chew was the eldest, and he had a brother and six sisters. His father worked in the Chartered Bank of Singapore, and his mother was a homemaker.[7]
On 12 November 1971, Chew was promoted as deputy director of medical services, the second highest position in the service.[23][24][25] Shortly after, in January 1972, Chew announced that the ministry is considering a scheme to make specialists treatments more accessible.[26][27] To prevent overcrowding at GH and underutilisation of other hospitals, Chew announced a scheme in January 1975 to divide Singapore into four zones, demarcated according to each zone's hospital resources and population size.[28][29][30] After the implementation, fewer patients were treated at GH.[31][32] Chew elaborated during the announcement:
The new scheme is aimed at rationalising the hospital services so that patients' load can be equally shared among the various regional hospitals. All the basic medical services provided will be of equal standard. Among the factors taken into account in determining the zones were the number of hospital beds available and the size of population in each zone. This is to ensure that there would be no overcrowding or underutilisation. Bus routes were also considered to ensure the medical institutions are accessible within each area. At the same time, in each zone the outpatient departments and maternal and child health clinics providing "primary medical care" form a ring round the regional hospital.[28][29]
In 1978, Chew was appointed as permanent secretary in the Ministry of Health and promoted to director of medical services.[33][34][35] In July 1978, a group of 70 medical students requested for a meeting with Chew, after the bond for first year medical scholars increased to S$81,000.[36] Minister for Health Toh Chin Chye and Chew agreed to meet with the students to "listen and clarify any queries",[37][38][39] but the students could not reach a collective decision on bond signing.[40][41] As such, Chew and the ministry decided to postpone the mandatory bond signing by the medical students, and reviewed its policy.[42][43]
In December 1979, medical officers in government hospitals urged for improvement to their employment terms and salary.[44][45] Due to a shortage in manpower, many of the doctors find themselves working 60 to 80 hours per week, compared to other civil servants who work a normal 44-hour week.[46] As such, in April 1980, Chew called upon retired doctors to work part time,[47][48] and in May 1980, allowance was increased for doctors, dentists, specialists and registrars.[49][50][51]
In August 1982, Chew was appointed as chairman of Yaohan Singapore.[4][52] In September 1983, Chew was also appointed as chairman of Singapore Biotech Pte Ltd. The company was established by the government to produce hepatitis B vaccines, under licence from Merck, Sharp and Dohme, for local usage and export to ASEAN and other countries such as Hong Kong.[5][53][54] The S$5 million plant was capable of producing six million doses of the vaccine.[55][56]
On 5 September 1984, Chew succeeded Sim Kee Boon as head of the civil service, while continuing his other two portfolios.[59][60] On 15 May 1985, Chew was part of the delegation that flew on the inaugural flight to Beijing via Shanghai, operated by Singapore Airlines.[61][62][63] On 30 September 1986, Chew officially opened a S$14 million clubhouse for civil servants, located along Tessensohn Road in Kallang.[64] In 1988, Chew was also part of the initial board of governors for the Institute of Policy Studies.[65]
Chew was married Jennifer Kam Thong Ho, and they have a daughter and son.[1][20]
In 2012, Chew underwent a cardiac valve surgery at the National University Hospital, but suffered from postoperative complications.[20] On 29 February 2012, Chew died of a heart failure.[1][2]
