INTRODUCTIONAs preparation against a possible avian flu pandemic, international and local health authorities have recommended seasonal influenza vaccination for all healthcare workers at geographical risk. This strategy not only reduces "background noise", but also chance of genetic shifts in avian influenza viruses when co-infection occurs. We evaluate the response of healthcare workers, stratified by professional groups, to a non-compulsory annual vaccination call, and make international comparisons with countries not at geographical risk.

MATERIALS AND METHODSA cross-sectional study was performed over the window period for vaccination for the 2004 to 2005 influenza season (northern hemisphere winter). The study population included all adult healthcare workers (aged < or =21 years) employed by a large acute care tertiary hospital.

RESULTSThe uptake rates among frontline caregivers--doctors >50%, nurses >65% and ancillary staff >70%--markedly exceeded many of our international counterparts results.

CONCLUSIONGiven its close proximity in time and space to the avian flu pandemic threat, Singapore healthcare workers responded seriously and positively to calls for preventive measures. Other factors, such as the removal of financial, physical and mental barriers, may have played important facilitative roles as well.

INTRODUCTIONUntil recently, vancomycin-resistant enterococcus (VRE) infection or colonisation was a rare occurrence in Singapore. The first major VRE outbreak involving a 1500-bed tertiary care institution in March 2005 presented major challenges in infection control and came at high costs. This study evaluates the predictors of VRE carriage based on patients' clinical and demographic profiles.

MATERIALS AND METHODSStudy patients were selected from the hospital inpatient census population during the VRE outbreak (aged 16 years or more). Clinical information from 84 cases and 377 controls were analysed.

RESULTSSignificant predictors of VRE carriage included: age>65 years Odds ratio (OR), 1.98; 95% CI (confidence interval), 1.14 to 3.43); female gender (OR, 2.15; 95% CI, 1.27 to 3.65); history of diabetes mellitus (OR, 1.94; 95% CI, 1.14 to 3.30), and staying in a crowded communal ward (OR, 2.75; 95% CI, 1.60 to 4.74). Each additional day of recent hospital stay also posed increased risk (OR, 1.03; 95% CI, 1.01 to 1.04).

CONCLUSIONElderly diabetic females with prolonged hospitalisation in crowded communal wards formed the profile that significantly predicted VRE carriage in this major hospital-wide outbreak of VRE in Singapore. It is imperative that active VRE surveillance and appropriate infection control measures be maintained in these wards to prevent future VRE outbreaks.

INTRODUCTIONThe influenza pandemic has generated much interest in the press and the medical world. We report our experience with 15 cases of severe novel influenza A H1N1 (2009) infections requiring intensive care. The aim of this review is to improve our preparedness for epidemics and pandemics by studying the most severely affected patients.

CLINICAL PICTUREDuring the epidemic, hospitals were required to provide data on all confirmed H1N1 cases admitted to an intensive care unit (ICU) to the Ministry of Health. We abstracted information from this dataset for this report. To highlight learning points, we reviewed the case notes of, and report, the fi ve most instructive cases.

TREATMENTThere were 15 cases admitted to an ICU from July 4, 2009 to August 30, 2009. Two patients died.

CONCLUSIONSThe lessons we wish to share include the following: preparedness should include having intermediate-care facilities that also provide single room isolation and skilled nursing abilities, stringent visitor screening should be implemented and influenza may trigger an acute myocardial infarction in persons with risk factors.

INTRODUCTION: In view of the important role of the environment in improving population health, implementation of health promotion programmes is recommended in living and working environments. Assessing the prevalence of such community health-promoting practices is important to identify gaps and make continuous and tangible improvements to health-promoting environments. We aimed to evaluate the inter-rater reliability of a composite scorecard used to assess the prevalence of community health-promoting practices in Singapore. METHODS: Inter-rater reliability for the use of the composite health promotion scorecards was evaluated in eight residential zones in the western region of Singapore. The assessment involved three raters, and each zone was evaluated by two raters. Health-promoting practices in residential zones were assessed based on 44 measurable elements under five domains - community support and resources, healthy behaviours, chronic conditions, mental health and common medical emergencies - in the composite scorecard using weighted kappa. The strength of agreement was determined based on Landis and Koch's classification method. RESULTS: A high degree of agreement (almost perfect-to-perfect) was observed between both raters for the measurable elements from most domains and subdomains. An exception was observed for the community support and resources domain, where there was a lower degree of agreement between the raters for a few elements. CONCLUSION The composite scorecard demonstrated a high degree of reliability and yielded similar scores for the same residential zone, even when used by different raters.
