The effects of communicating illness diagnostic and treatment information and C-reactive protein test results on people's antibiotic expectations
Objectives
Patients' expectations for antibiotics are among the strongest predictors of clinicians' decisions to overprescribe antibiotics. In this registered report, we used a signal detection theory framework to investigate the experimental effects of the communication interventions that family physicians can use to reduce patients' diagnostic uncertainty, and consequently, their antibiotic expectations.
Methods
UK participants (N = 769) read hypothetical consultations for respiratory tract infections and were randomly assigned to one of three conditions: standard information (control), recommended information about the nature of the illness and antibiotic efficacy (recommended communication) or recommended information accompanied by point-of-care test results (recommended communication and CRP). Using a multilevel Bayesian probit regression, we estimated both decision bias (criterion) and sensitivity (d-prime).
Results
Aligned with our bias hypotheses, participants displayed a more liberal antibiotic bias in the control condition compared to both the recommended communication (Δc = −1.34, 95% CI [−1.57, −1.11]) and the recommended communication and CRP (Δc = −1.73, 95% CI [−1.99, −1.48]) conditions. They also showed greater liberal bias in the recommended communication condition compared to the recommended communication and CRP condition (Δc = −0.39, 95% CI [−0.65, 0.13]). Aligned with our sensitivity hypotheses, participants displayed significantly higher sensitivity in both the recommended communication (Δd' = 2.34, 95% CI [1.92, 2.79]) and the recommended communication and CRP (Δd' = 2.49, 95% CI [2.08, 2.95]) conditions compared to control.
Conclusions
Simple, evidence-based communication strategies—particularly when combined with diagnostic test results—can reduce antibiotic expectations, offering practical tools for clinicians to support appropriate prescribing.
期刊介绍：
The focus of the British Journal of Health Psychology is to publish original research on various aspects of psychology that are related to health, health-related behavior, and illness throughout a person's life. The journal specifically seeks articles that are based on health psychology theory or discuss theoretical matters within the field.
