What is a doctor-shopping phenomenon?
You may wonder what doctor-shopping is. In a series of publications, I attempted to explain the phenomenon of doctor-shopping and describe its characteristics.
Purpose
Doctor-shopping has significant consequences for patients and payers, indicating misuse of drugs, polypharmacy, reduced continuity of care, and increased medical expenses. To shed light on this issue, I aimed to review literature describing doctor-shoppers in both adult and pediatric populations. My goal was to identify factors associated with doctor-shopping behavior and investigate the doctor-related factors that might contribute to this phenomenon.
Approach
Several search strategies were tested to refine the final searches, facilitating the analysis of the doctor-shopping phenomenon. A publication plan was developed to target the health policy audience, and comprehensive full-length papers and posters were planned to disseminate the real-world data findings.
Results
Two papers were successfully published in peer-reviewed journals, and three posters were accepted for presentation at the ISPOR conference. The research has been well-received by the scientific community; to date, it has been cited over 75 times by other researchers.
