US hospitals face a disincentive to improve care because they make drastically more money when surgery goes wrong than when a patient is discharged with no complications, a study published Tuesday found.
"We found clear evidence that reducing harm and improving quality is perversely penalised in our current health care system," said study author Sunil Eappen, chief medical officer of Massachusetts Eye and Ear Infirmary.
An estimated $400 billion is spent on surgery in the United States every year.
Privately insured patients up hospital profits
Privately insured patients with complications provide hospitals with a 330% higher profit margin than those whose surgeries went smoothly, the study published in the Journal of the American Medical Association found.
Patients whose bills are paid by Medicare - a government insurance plan for the elderly and disabled - produced a 190% higher profit margin when complications arose following surgery.
"It's been known that hospitals are not rewarded for quality," said study author Atul Gawande, a professor at the Harvard School of Public Health and director of Ariadne Labs.
"But it hadn't been recognised exactly how much more money they make when harm is done."
While effective methods to reduce complications have been identified by researchers, the authors said that hospitals have been slow to implement them.
Health care payment reform is necessary
"This is clear indication that health care payment reform is necessary," Gawande added. "Hospitals should gain, not lose, financially from reducing harm."
The researchers analysed data from 34 256 surgical inpatients discharged in 2010 from a non-profit, 12-hospital system in the southern United States. A total of 1 820 procedures were identified with at least one complication.
They found that complications were associated with a $39 017 (R356 701.94) higher profit margin per patient (R511 757 vs. R154 900) for privately insured patients. For Medicare patients, the profit margin per patient was higher by R15 996 (R33 722 vs. R17 194).
Conversely, profit margins were significantly lower when complications arouse with patients who paid out of pocket or through the government-funded Medicaid program to assist low-income children and adults.
That means that while so-called "safety-net" hospitals which primarily treat patients who are either uninsured or covered by Medicaid, reducing complications could improve financial performance.
But most hospitals would see their financial performance hurt if they reduced complications.
