C B Finn studies the effectiveness of real-time hormone monitoring during parathyroid surgery to enhance patient outcomes for those with primary hyperparathyroidism, a condition characterized by excessive levels of parathyroid hormone leading to high calcium levels in the blood. They have developed a method to predict surgical success by measuring the drop in parathyroid hormone (PTH) during the procedure. Finn is also dedicated to understanding and addressing the challenges that female surgeons encounter as they grow their practices, aiming to create a more equitable environment in the surgical field.
Key findings
A 50-65% drop in PTH during parathyroid surgery reliably indicates successful treatment and avoids the risk of dangerous hypocalcemia (low calcium levels) afterward, based on data from over 1,000 patients.
Women surgeons face specific social and institutional barriers that hinder their clinical practice development, as identified in qualitative research.

2025
American journal of surgery
Rosenthal JW, Finn CB, Hwang J, Sharpe JE, Williams ST +4 more
Plain English This study looked at how many patients had adrenal surgery done as outpatient procedures from 2016 to 2020. Researchers found that the percentage of these surgeries performed on an outpatient basis increased from 44.1% in 2016 to 59.2% in 2020, with similar costs and readmission rates regardless of whether patients stayed overnight or were discharged the same day. This is important because it shows that more patients can go home the same day without compromising their safety or increasing costs.
Who this helps: This helps patients who may prefer to recover at home rather than in a hospital.
Predicting cure and hypocalcemia by intraoperative parathyroid hormone decline in normohormonal primary hyperparathyroidism: A multi-institutional validation study.
2025
Surgery
Kravchenko T, Finn CB, Fraker DL, Kelz RR, Cunningham C +2 more
Plain English Researchers studied whether a simple blood test during parathyroid surgery—measuring how much a hormone called PTH drops during the operation—could predict whether the surgery would successfully cure a specific type of parathyroid disease and avoid a dangerous drop in calcium levels afterward. They tested this prediction method in over 1,000 patients from multiple hospitals and confirmed that a 50-65% drop in PTH during surgery reliably indicates the operation will work and help doctors avoid dangerously low calcium levels after surgery. This matters because doctors can now use this quick, real-time measurement during surgery to know whether they've removed the right amount of diseased tissue, without having to wait for results afterward.
