Summary
Higher volume physicians performing brachytherapy were linked to lower recurrence and prostate cancer death rates in men. Provider volume did not significantly impact complication rates after treatment.
Area of Science:
- Urology
- Oncology
- Health Services Research
Background:
- Brachytherapy is a common treatment for prostate cancer.
- Understanding the impact of provider experience on treatment outcomes is crucial for patient care.
Purpose of the Study:
- To assess the relationship between healthcare provider volume and patient outcomes after brachytherapy for prostate cancer.
Main Methods:
- Analysis of Medicare claims for men over 65 diagnosed with prostate cancer and treated with brachytherapy.
- Calculation of physician and hospital case volumes from 1991-2001.
- Outcomes assessed included recurrence, prostate cancer death, all deaths, and complications, adjusted for patient and treatment characteristics.
Main Results:
- Higher volume physicians were associated with lower recurrence rates (HR 0.89) and prostate cancer death rates (HR 0.80).
- Higher volume hospitals showed a slight reduction in combined complication diagnoses and procedures (OR 0.94).
- No significant association was found between provider volume and overall mortality or complications.
Conclusions:
- Treatment by higher volume physicians for brachytherapy is associated with improved survival outcomes for prostate cancer patients.
- Provider volume did not demonstrate a clear link to complication rates following brachytherapy.
