INTRODUCTION:
Antimicrobial resistance (AMR) poses a critical global health threat, with millions of deaths attributed to it annually. Antibiotic stewardship to combat AMR is the responsibility of all healthcare professionals. Despite evidence suggesting that it is unnecessary, dentists routinely prescribe prophylactic antibiotics following third molar (3M) surgeries.
METHOD:
This mixed-methods study examined the behavioural barriers influencing antibiotic prescribing practices within the Division of Oral and Maxillofacial Surgery at the National University Centre for Oral Health Singapore. This study used the capability, opportunity and motivation for behavioural change or COM-B framework to implement interventions targeting the behavioural barriers.
RESULTS:
Pre- and post-intervention data over 6 months showed a significant reduction in antibiotic prescriptions from 84.45% to 20.89%, following the implementation of COM-B strategies (P<0.001). Qualitative feedback from focus group discussions highlighted a positive shift in clinicians' attitudes towards antibiotic reduction, acknowledging the minimal infection risk associated with non-prescribing practices. Notably, complication rates remained stable throughout the study period, indicating no adverse effects from reduced antibiotic usage.
CONCLUSION
These findings demonstrated that the COM-B model can be successfully applied to modify deeply ingrained prescription habits, and underscored the effectiveness of a structured behavioural change intervention in enhancing compliance with antibiotic stewardship guidelines. The study advocates continuation of initiatives to sustain this positive trend and mitigate AMR in clinical practice.

INTRODUCTION:
The coronavirus disease 2019 (COVID-19) pandemic has had an unprecedented impact in Asia and has placed significant burden on already stretched healthcare systems. We examined the impact of COVID-19 on the safety attitudes among healthcare workers (HCWs), as well as their associated demographic and occupational factors, and measures of burnout, depression and anxiety.
METHODS:
A cross-sectional survey study utilising snowball sampling was performed involving doctors, nurses and allied health professions from 23 hospitals in Singapore, Malaysia, India and Indonesia between 29 May 2020 and 13 July 2020. This survey collated demographic data and workplace conditions and included three validated questionnaires: the Safety Attitudes Questionnaire (SAQ), Oldenburg Burnout Inventory and Hospital Anxiety and Depression Scale. We performed multivariate mixed-model regression to assess independent associations with the SAQ total percentage agree rate (PAR).
RESULTS:
We obtained 3,163 responses. The SAQ total PARs were found to be 35.7%, 15.0%, 51.0% and 3.3% among the respondents from Singapore, Malaysia, India and Indonesia, respectively. Burnout scores were highest among respondents from Indonesia and lowest among respondents from India (70.9%-85.4% vs. 56.3%-63.6%, respectively). Multivariate analyses revealed that meeting burnout and depression thresholds and shifts lasting ≥12 h were significantly associated with lower SAQ total PAR.
CONCLUSION
Addressing the factors contributing to high burnout and depression and placing strict limits on work hours per shift may contribute significantly towards improving safety culture among HCWs and should remain priorities during the pandemic.

Introduction: Doctors are known to deal with high occupational stress, causing increased risk of depression, anxiety and stress.Nevertheless, the prevalence and associatedfactors of depression, anxiety and stress among registered doctorsworking in 24 public hospitals in Sabah, Malaysia are not known yet. Methods: This cross-sectional study was conducted using convenient sampling from September-October 2018. The data of 21-item Depression Anxiety Stress Scale (DASS-21) was collected via online link anonymously. Results: Among 314 doctors, majority of them were females (62.1%), mean age 29 (SD 2.72), non-Sabahan (82.8%), Malays (46.8%), not married (78.3%) and medical officers (93.6%). Prevalence of severe/extremely severe anxiety symptoms was 27.4%,depression (22.9%) and stress (18.5%). Doctors perceiving themselves to be depressed, anxious and/or stressed were more likely to develop the corresponding symptoms. Females and Chinese were twice more likely to report anxiety symptoms. Being married had protective effect against depressive symptoms, while working in same hospital for longer time had a significant but weak protective effect against anxiety and stress symptoms. Conclusions: Mental health issue among doctors is substantial and need to be addressed effectively for the benefit of their life, patients and country.
