Impact of Preference Signaling on Radiology Residency Placements

1. Background – What “Preference Signaling” Means in Radiology
• Two years ago, the diagnostic radiology (DR) residency application system introduced a new step called preference signaling.
• In simple terms, this allowed applicants to directly tell certain programs: “You are one of my top choices.”
• The goal was to help programs identify genuinely interested candidates among hundreds of applications.
2. Rising Competitiveness in Radiology
• The number of people applying for DR residencies has been steadily going up — from 1,893 applicants in 2019 to 2,409 in 2023.
• That’s an average yearly growth of about 4.2%.
• In 2023, the match rate (the percentage of U.S. MD seniors who successfully got into a program) was 81% — the highest competitiveness seen since 2001.
3. How the Study Was Done
• Researchers examined data from 1,614 applicants between 2017 and 2024 using the Texas STAR database.
• They compared results from before and after preference signaling was introduced.
• They looked at academic scores, research experience, interviews, and final match results to see how signaling affected outcomes.
4. Main Findings
• On average, applicants who used preference signaling applied to about 10 more programs than those who didn’t.
• They ended up with about 4 fewer interview invitations overall — but here’s the key:
• They were far more likely to be invited to interview at programs they had signaled.
• They were also much more likely to match there.
• Statistically, the odds of getting an interview at a signaled program were 14.43 times higher.
• The odds of matching there were 17.34 times higher.
• In the 2023–2024 cycle, 71% of all matched applicants ended up in a program they had signaled.
5. Gold vs. Silver Signals
• In this system, applicants could send “gold” or “silver” signals to rank their interest.
• Gold signals had the strongest effect, but even silver signals improved chances compared to sending none.
6. Other Factors That Help Match Chances
• Doing an away rotation (spending time training at a program before applying).
• Having geographic ties to the program’s location.
• Receiving clinical honors in medical school.
• Scoring higher on the USMLE Step 2 exam.
• The best results came when away rotations were combined with signaling:
• 70% of applicants matched at programs where they both rotated and signaled.
• Without signaling, only 8% matched at programs where they had done an away rotation.
In this context, “rotation” means a short-term training period where a medical student or resident works at a hospital or clinic — often outside their main institution — to gain experience and make connections.
• An away rotation is when you do this training at another program you might want to join in the future.
• It’s like a trial period: you get to show your skills, meet the team, and learn how they work — and they get to know you personally.
So, in the study:
• 70% of applicants who both did an away rotation and signaled that same program got accepted there.
• But without signaling, only 8% matched at programs where they had rotated.
This shows that doing an away rotation helps, but combining it with clear communication of interest (“signaling”) is much more powerful.
7. Conclusion
• Preference signaling works well for improving the chances of matching at targeted programs — but it doesn’t stop applicants from sending too many applications.
• Experts suggest discussing how many signals each applicant should be allowed in the future to make the process more efficient.
