Researchers examined data from 36,210 adult tonsillectomy patients and found that 20 percent had a complication, 10 percent visited an emergency room, and about 1.5 percent were admitted to a hospital within 14 days of the procedure.
The new study is the first of its kind to examine a large adult population, across institutions and provider practices and over multiple years using the Truven Health MarketScan Database.
Previous studies focused on small numbers of patients within particular institutions and have not considered a wider spectrum of complications beyond post-tonsillectomy hemorrhage.
“Since 1973, John Wenneberg and his colleagues at Dartmouth have been examining variation in the rates of tonsillectomy performed across regions, trying to explain why such wide variation is observed,” says Dennis Scanlon, professor of health policy and administration at Penn State.
“In other words, why are some patients significantly more likely to get the procedure in some areas of the country compared to others? Yet despite the wide degree of regional variation reported, most of which has been documented in pediatric populations, much less is known about the safety and risks to patients who undergo the procedure, particularly adult patients.”
Complications can raise costs
The new study, published in the journal Otolaryngology—Head and Neck Surgery, shows that six percent of adult patients were treated for postoperative hemorrhage; 2 percent were treated for dehydration; and 11 percent were treated for ear, nose, or throat pain within 14 days of surgery.
“These estimated complication rates are significantly higher than those reported in prior studies,” Scanlon says.
The researchers also investigated expenditures associated with adult tonsillectomies and found that, on average, the amount paid for a tonsillectomy without complication was $3,832, whereas tonsillectomy with hemorrhage resulted in an average expenditure of $6,388.
“Our results highlight the challenges patients face when making informed decisions about medical and surgical treatments, as well as the excess costs and harm incurred due to complications,” Scanlon says.
“Patients expect to compare the risks and benefits of treatment options, but as our study shows, credible patient-centered information is often lacking, even for a common procedure that has been in practice for many, many years.
“The availability of important risk and benefit information should be expedited, and providers need to be trained to engage patients in how to use this information to make informed choices.”
