Objectives: Pre-COVID-19 pandemic, patients who attended the emergency department (ED) for upper respiratory tract infection (URTI) were more likely to receive antibiotics if they expected them. These expectations could have changed with the change in health-seeking behaviour during the pandemic. We assessed the factors associated with antibiotics expectation and receipt for uncomplicated URTI patients in four Singapore EDs during the COVID-19 pandemic. Methods: We conducted a cross-sectional study on adult patients with URTI from March 2021 to March 2022 in four Singapore EDs and assessed the determinants of antibiotics expectation and receipt using multivariable logistic regression models. We also assessed the reasons patients expect antibiotics during their ED visit. Results: Among 681 patients, 31.0% expected antibiotics while 8.7% received antibiotics during their ED visit. Factors (adjusted odds ratio [95% confidence interval]) that significantly influenced expectation for antibiotics include: 1) prior consultation for current illness with (6.56 [3.30-13.11]) or without (1.50 [1.01-2.23]) antibiotics prescribed; 2) anticipation for COVID-19 test (1.56 [1.01-2.41]); and 3) poor (2.16 [1.26-3.68]) to moderate (2.26 [1.33-3.84]) knowledge on antibiotics use and resistance. Patients expecting antibiotics were 10.6 times (10.64 [5.34-21.17]) more likely to receive antibiotics. Those with tertiary education were twice (2.20 [1.09-4.43]) as likely to receive antibiotics. Conclusion: In conclusion, patients with URTI who expected antibiotics to be prescribed remained more likely to receive it during the COVID-19 pandemic. This highlights the need for more public education on the non-necessity for antibiotics for URTI and COVID-19 to address the problem of antibiotic resistance. (c) 2023 The Author(s).

Background: Antimicrobial stewardship programs attempting to optimize antibiotic therapy and clinical outcomes mainly focus on inpatient and outpatient settings. The lack of antimicrobial stewardship program studies in the emergency department (ED) represents a gap in tackling the problem of antimicrobial resistance as EDs treat a substantial number of upper respiratory tract infection cases throughout the year. Objective: We intend to implement two evidence-based interventions: (1) patient education and (2) providing physician feedback on their prescribing rates. We will incorporate evidence from a literature review and contextualizing the interventions based on findings from a local qualitative study. Methods: Our study uses a quasi-experimental design to evaluate the effects of interventions over time in the EDs of 4 public hospitals in Singapore. We will include an initial control period of 18 months. In the next 6 months, we will randomize 2 EDs to receive 1 intervention (ie, patient education) and the other 2 EDs to receive the alternative intervention (ie, physician feedback). All EDs will receive the second intervention in the subsequent 6 months on top of the ongoing intervention. Data will be collected for another 6 months to assess the persistence of the intervention effects. The information leaflets will be handed to patients at the EDs before they consult with the physician, while feedback to individual physicians by senior doctors is in the form of electronic text messages. The feedback will contain the physicians’ antibiotic prescribing rate compared with the departments’ overall antibiotic prescribing rate and a bite-size message on good antibiotic prescribing practices. Results: We will analyze the data using segmented regression with difference-in-difference estimation to account for concurrent cluster comparisons. Conclusions: Our proposed study assesses the effectiveness of evidence-based, context-specific interventions to optimize antibiotic prescribing in EDs. These interventions are aligned with Singapore’s national effort to tackle antimicrobial resistance and can be scaled up if successful.

Objectives: Inappropriate antibiotic prescribing for acute upper respiratory tract infections (URTIs) is a significant problem in emergency departments (EDs) worldwide. In this study, we separately evaluated the effectiveness of physician feedback and patient education in reducing antibiotic prescribing for URTIs in the ED setting. Methods: We conducted a quasi-experimental study across four large adult EDs in Singapore from January 2021 to December 2023. After a baseline period (18 months), two EDs were randomly assigned to either implement physician feedback or patient education for six months (intervention period 1), and all EDs subsequently implemented both interventions in the next six months (intervention period 2). Hierarchical segmented logistic regression was used to assess the effectiveness of the interventions in reducing weekly antibiotic prescribing for URTIs. Results: In the two EDs that implemented physician feedback first, there was a significant decrease in the trend of weekly antibiotics prescribed (AOR 0.981 [95% CI (0.964, 0.998)]) compared to the last 6 months of the pre-intervention period. Adding patient education in the next phase (intervention period 2) did not further reduce the trend of weekly antibiotics prescribed. For the second group of two EDs that implemented patient education first, there was no significant reduction in the weekly antibiotic prescribing trend during intervention period 1. With the addition of physician feedback, a significant decline in the trend of weekly antibiotics prescribed was observed in intervention period 2 (AOR 0.921 [95% CI (0.903,0.940)]). Conclusions: Physician feedback alone can reduce antibiotic prescribing for URTIs in EDs. Further research is warranted to assess the effectiveness of patient education involving multi-modal educational channels co-created with patients.
