Study finds digital healthcare matching reduces ER visits and antibiotic overuse in Sweden

Summary

This research article examines how digital healthcare platforms reduce geographic barriers, enabling better matching between patients and physicians. Using Swedish nationwide online healthcare data with time-conditional random assignment, the study finds that matching high-risk patients with doctors who are effective at reducing Emergency Room visits lowers such visits by 4.4% and reduces counter-guideline antibiotic prescriptions by 3.1%. The research identifies limited trade-offs in matching due to horizontal differentiation among doctors and varied patient needs, allowing simultaneous improvement across multiple outcomes. The findings highlight the potential for care reorganization when geographic constraints are lifted, though efficiency gains also affect equity considerations.
