Higher labor costs cut into income last year at the Mayo Clinic, according to numbers being released Monday, as the state's largest employer didn't score a repeat of 2014's record financial results.
The income decline wasn't a surprise, clinic officials said, and reflected increased staffing needs as sicker patients spent more time in the hospital.
Mayo Clinic saw more pension costs in 2015, too, and needed more staff as it launched information technology projects plus a next-generation radiation treatment center in Rochester.
Employment during the year grew by more than 4,000 jobs to 64,033 people across Mayo's six-state network of hospitals and clinics.
"We did not plan to have another record year," said Pat McCarty, vice chair of financial planning and analysis. "We're in more of an investment mode now. … We're growing some of our staff to support those new investments."
The results come as the financial outlook for nonprofit hospitals is stable, according to a report this month from Standard & Poor's. Expanded Medicaid coverage in many states, including Minnesota, has helped provide at least a short-term boost in the number of patients.
Medicaid was a bigger source of gross revenue for Mayo Clinic in 2015, McCarty said, but there was even more growth in the share covered by the federal Medicare program. He attributed the increase to baby boomers getting older.
In 2015, Mayo Clinic posted income of $526 million on $10.3 billion in revenue, for a margin of about 5 percent. That's the sort of margin the clinic targets most years, McCarty said, adding that the previous year's $834 million in income was unusually high.
