BACKGROUND Accurate forecasting of emergency department (ED) attendances can be a valuable tool for micro and macro level planning. METHODS Data for analysis was the counts of daily patient attendances at the ED of an acute care regional general hospital from July 2005 to Mar 2008. Patients were stratified into three acuity categories; i.e. P1, P2 and P3,(More)
Between 1 and 22 March 2003, a nosocomial outbreak of Severe Acute Respiratory Syndrome (SARS) occurred at the Communicable Disease Centre in Tan Tock Seng Hospital, Singapore, the national treatment and isolation facility for patients with SARS. A case-control study with 36 cases and 50 controls was conducted of factors associated with the transmission of(More)
A total of 80 cooling tower water samples were investigated for legionellae using both cultural and polymerase chain reaction (PCR) methods. PCR was performed with the Perkin Elmer EnviroAmp Legionella kit. Forty-seven samples (58.8%) were found positive by both methods; 29 samples (36.3%) were positive by PCR only, while four samples (5%) showed PCR(More)
This paper is focused on the factors causing long patient waiting time/clinic overtime in outpatient clinics and how to mitigate them using discrete event simulation. A two-week period of data collection is conducted in an outpatient clinic of a Singapore government hospital. Detailed time study from patient arrival to patient departure is conducted, and(More)
BACKGROUND The world is short of 7.2 million health-care workers and this figure is growing. The shortage of teachers is even greater, which limits traditional education modes. eLearning may help overcome this training need. Offline eLearning is useful in remote and resource-limited settings with poor internet access. To inform investments in offline(More)
Cadmium concentrations in whole blood were measured in subjects with no occupational exposure to cadmium. The study covered 128 males and 150 females from the three main ethnic groups in Singapore (namely Chinese, Malays and Indians). The geometric means (GM) of blood cadmium (CdB) levels of non-smoking males and females were 0.21 microgram/l and 0.26(More)
STUDY OBJECTIVE Emergency department (ED) waiting times can affect patient satisfaction and quality of care. We develop and validate a model that predicts an individual patient's median and 95th percentile waiting time by using only data available at triage. METHODS From the existing ED information system, we extracted date and time of triage completion,(More)
Tuberculosis was responsible for 177 deaths in 1987. This study evaluated the accuracy of tuberculosis death certification by hospital doctors and general practitioners in 111 cases where hospital case-notes were available for verification. It revealed that only 49 cases (44%) died of active tuberculosis, 12 (11%) died of late effects of tuberculosis and 41(More)
During the period 1989 to 1996, a total of 372 cases of melioidosis, with 147 deaths, were reported, giving a mean annual incidence rate of 1.7 per 100,000 population and a case-fatality rate of 39.5%. Majority (89%) of the clinical cases were confirmed by culture of Burkholderia pseudomallei, while the others were presumptive cases based on a single blood(More)
OBJECTIVES To be able to predict, at the time of triage, whether a need for hospital admission exists for emergency department (ED) patients may constitute useful information that could contribute to systemwide hospital changes designed to improve ED throughput. The objective of this study was to develop and validate a predictive model to assess whether a(More)
