Matthew Kircher, MD, and colleagues examined one of the costs associated with surgery to remove a type of cyst, called a cholesteatoma, from the middle ear. Otologists routinely send specimens to the pathology lab, but the study found this doesn’t appear to be necessary.
The study found that in 178 cases involving seven otologists, there was virtually perfect agreement between the otologists’ findings and the official diagnoses from the pathology reports. Since the otologists were always right, there appeared to be no need to go through the expense of confirming their findings.
Results are published online ahead of print in the Laryngoscope journal.
The results are similar to other studies that have concluded it’s not always necessary to send tonsillectomy specimens to the pathology lab.
The increased cost of routine cholesteatoma pathologic evaluations should be considered among future health-care cost-containing measures because the clinical utility appears to be low, Kircher and colleagues wrote.
About 18,000 cases of cholesteatoma are treated each year in the United States. Medicare pays $62 for a microscopic evaluation of a specimen, while private insurers can pay much more. Researchers conservatively estimated that not doing these evaluations could save more than $1 million per year.
“Although this number is small when considering the larger context of health-care spending, we believe that this cost analysis represents a simple health-care cost-containment opportunity,” Kircher and colleagues wrote.
A cholesteatoma is a collection of trapped dead cells and other waste material that slough off into a pocket in the middle ear. As the cyst grows, it can break down middle ear bones and other nearby structures, causing hearing loss, dizziness, tinnitus and facial paralysis.
The study was conducted at the Michigan Ear Institute, where Kircher (first author) completed a neurotology fellowship before recently joining Loyola.
Kircher and colleagues reviewed 178 cases and found the “Cohen’s kappa value” between otologists and pathologists was 0.93. A Cohen kappa value measures the agreement between two raters. Statistically, any rating higher than 0.81 is considered a perfect agreement. Researchers said larger studies might help to confirm their findings.
Kircher is an assistant professor in the Department of Otolaryngology at Loyola University Chicago Stritch School of Medicine. His specialties include otology, neurotology and cranial base surgery.
