Knowledge, attitudes and practices towards COVID-19 among multiethnic elderly Asian residents in Singapore: a mixed-methods study

INTRODUCTION@#We investigated the knowledge, attitudes and practice (KAP) towards coronavirus disease 2019 (COVID-19) and its related preventive measures in Singaporeans aged ≥60 years.@*METHODS@#This was a population-based, cross-sectional, mixed-methods study (13 May 2020-9 June 2020) of participants aged ≥ 60 years. Self-reported KAP about ten symptoms and six government-endorsed preventive measures related to COVID-19 were evaluated. Multivariable regression models were used to identify sociodemographic and health-related factors associated with KAP in our sample. Associations between knowledge/attitude scores and practice categories were determined using logistic regression. Seventy-eight participants were interviewed qualitatively about the practice of additional preventive measures and data were analysed thematically.@*RESULTS@#Mean awareness score of COVID-19 symptoms was 7.2/10. The most known symptom was fever (93.0%) and the least known was diarrhoea (33.5%). Most participants knew all six preventive measures (90.4%), perceived them as effective (78.7%) and practised 'wear a mask' (97.2%). Indians, Malays and participants living in smaller housing had poorer mean scores for knowledge of COVID-19 symptoms. Older participants had poorer attitudes towards preventive measures. Compared to Chinese, Indians had lower odds of practising three out of six recommendations. A one-point increase in score for knowledge and attitudes regarding preventive measures resulted in higher odds of always practising three of six and two of six measures, respectively. Qualitative interviews revealed use of other preventive measures, for example, maintaining a healthy lifestyle.@*CONCLUSIONS@#Elderly Singaporeans displayed high levels of KAP about COVID-19 and its related preventive measures, with a positive association between levels of knowledge/attitude and practice. However, important ethnic and socioeconomic disparities were evident, indicating that key vulnerabilities remain, which require immediate attention.

The excess financial burden of multidrug resistance in severe gram-negative infections in Singaporean hospitals

<p><b>INTRODUCTION</b>Multidrug-resistant (MDR) Gram-negative healthcare-associated infections are prevalent in Singaporean hospitals. An accurate assessment of the socioeconomic impact of these infections is necessary in order to facilitate appropriate resource allocation, and to judge the costeffectiveness of targeted interventions.</p><p><b>MATERIALS AND METHODS</b>A retrospective cohort study involving inpatients with healthcare-associated Gram-negative bacteraemia at 2 large Singaporean hospitals was conducted to determine the hospitalisation costs attributed to multidrug resistance, and to elucidate factors affecting the financial impact of these infections. Data were obtained from hospital administrative, clinical and financial records, and analysed using a multivariate linear regression model.</p><p><b>RESULTS</b>There were 525 survivors of healthcare-associated Gram-negative bacteraemia in the study cohort, with 224 MDR cases. MDR bacteraemia, concomitant skin and soft tissue infection, higher APACHE II score, ICU stay, and appropriate definitive antibiotic therapy were independently associated with higher total hospitalisation costs, whereas higher Charlson comorbidity index and concomitant urinary tract infection were associated with lower costs. The excess hospitalisation costs attributed to MDR infection was $8638.58. In the study cohort, on average, 62.3% of the excess cost attributed to MDR infection was paid for by government subvention.</p><p><b>CONCLUSION</b>Multidrug resistance in healthcare-associated Gram-negative bacteraemia is associated with higher financial costs--a significant proportion of which are subsidised by public funding in the form of governmental subvention. More active interventions aimed at controlling antimicrobial resistance are warranted, and the results of our study also provide possible benchmarks against which the cost-effectiveness of such interventions can be assessed.</p>
