The results showed a significantly high level of inappropriate use of antimicrobial prophylaxis in paediatric surgery in Singapore. However, when the individual factors such as appropriate choice of antibiotics, appropriate timing and duration were considered, the situation was very similar to the results obtained from overseas studies.

Background Closed Loop Medication Management System (CLMMS) is an end‐to‐end medication delivery system comprising seamless interfaces, independent verification processes and information feedback to improve safety and quality. Aim Following implementation of a CLMMS at an academic medical centre in Singapore, this study was conducted to identify any safety issues and areas for quality improvement. Method A direct observational study was conducted in the wards, inpatient pharmacy and unit‐dose satellite pharmacy. The numbers and types of medication errors in prescribing, supply and administration were observed and recorded to calculate the error rate. Events that have the potential to cause errors were also observed. Results The prescribing error rate was 1.3% and the most common prescribing error was dose error. Supply error rate was 0.7% in which labelling error occurred most frequently. Workflow issues were the most common occurrences that could potentially cause prescribing and supply errors. The administration error rate was 7.3%, and wrong drug preparation technique was most commonly seen. Improper procedure in the use of personal digital assistant was the most common event that could potentially lead to an administration error. Conclusion This study was instrumental in identifying important medication safety gaps in order to improve the inpatient CLMMS. Although a failure mode and effects analysis was performed prior to implementation of the system, unintended error types may still be introduced. Hence a post‐implementation audit is necessary to address such issues to ensure that the CLMMS objective of improving medication safety is achieved.

The majority of dosing regimens of vancomycin was consistent with guideline criteria. The most evident problem was the sub-optimal use of the monitoring of vancomycin serum levels. The information derived from this study may be used as a for further study and for the development of strategies for optimize vancomycin usage.

equipment that is able to barcode scan medications, read aloud the medication and the concentration and print a label of the appropriate concentration in the appropriate colour code. We decided to test this system in our facility to identify risks, benefits and usability. Our project comprised a baseline survey (25 anaesthesia cases during which 212 syringes were prepared from 223 drugs), an observational study (47 cases with 330 syringes prepared) and a user acceptability survey. The baseline compliance with all labelling requirements was 58%. In the observational study the compliance using the Codonics system was 98.6% versus 63.8% with conventional labelling. In the user acceptability survey the majority agreed the Codonics machine was easy to use, more legible and adhered with better security than the conventional preprinted label. However, most were neutral when asked about the likelihood of flexibility and customisation and were dissatisfied with the increased workload. Our findings suggest that the Codonics labelling machine is user-friendly and it improved syringe labelling compliance in our study. However, staff need to be willing to follow proper labelling workflow rather than batch label during preparation. Future syringe labelling equipment developers need to concentrate on user interface issues to reduce human factor and workflow problems. Support logistics are also an important consideration prior to implementation of any new labelling system.

Asthma is the most common chronic disorder of childhood. The aim of this study was to assess prescription trends of asthma medications to provide a measure to evaluate treatment practices and compliance with established international practice guidelines. A retrospective study of data obtained from outpatient prescription databases (2001-2010) of the University Children's Medical Institute for children aged 0-18 years was performed. The following drugs were included: short-acting beta-agonists (SABAs), long-acting beta-agonists in combination with inhaled corticosteroids (LABA-ICSs), ICS, and leukotriene receptor antagonists. Statistical analysis of prescription trends was performed with linear regression to determine the trends in prescription of controller medications. From 2001 to 2010, the number of patients who were prescribed SABA increased significantly by 72% (p = 0.016). The increases in ICS patient numbers and ICS/SABA drug unit ratios were significant only in the school-going (>5 years) age group. There was a trend away from the use of nebulized SABA and ICS, although this was statistically insignificant. LABA-ICS patient numbers decreased significantly by 32.4% (p = 0.003), especially in preschoolers (1-5 years). There was a corresponding rise in montelukast patient numbers by 194.6% (p = 0.009) and montelukast/SABA ratio by 345.3% (p = 0.032) in preschoolers (aged 1-5 years). Montelukast patient numbers, but not the montelukast/SABA ratio, increased in school-going children. The move away from LABA-ICS combination especially in younger children and a tendency toward more montelukast usage is a reflection of practice preferences in accordance with current international guidelines in young children.
