AMES— The University of Iowa Hospitals and Clinics revenue is in the black, increasing by more than 11 percent for fiscal 2011 compared with the previous year.

According to presentation given to the state Board of Regents Wednesday, revenue totaled $606,712 through January 2011, an increase from $543,703 over the same period in 2010. Patient revenue accounted for $577,930.

In addition, UIHC officials said the cash flow operating margin increased 47.6 percent — reaching $82,758 for fiscal 2011.

“Our performance continues to be strong,” said Jean Robillard, the UI vice president for Medical Affairs.

The numbers come on the heels of an influx in patient days, which reached 116,658 from July 2010 to January 2011 compared with 106,434 for the previous year. Officials saw a 16.2 percent increase in in-patient and out-patient surgeries in the same time frame.

The UIHC experienced an average of 43 patients per day, said CFO Ken Fisher, an associate vice president for Medical Affairs. The number is higher than the budgeted 30 patients.

“That translates into a lot more net revenue for the organization,” Fisher said.

Patients are mostly concentrated in the Surgery Department, Fisher said, with a large growth in ambulatory surgeries.

But Robillard said concerns exist over the length of stay with patients, who are exceeding the budgeted length of stay by an average of 5.1 percent.

The hospital is also seeing large numbers from the emergency room.

The number of patients visiting the emergency room increased from 29,995 to 32,506 over the last two fiscal years, said CEO Ken Kates, an associate vice president for Medical Affairs.

“There, when the ER is packed, [we] have concerns with patients moving in and out to other areas, but I feel this is something we’re equipped to handle,” Kates said.

Even with the increases, they are 13,000 patients below what was budgeted for the current fiscal year, Fisher said. Nearly 40 percent of those numbers came in February, directly related to the Feb. 1 blizzard.

“To have low numbers in an already short month is obviously going to have an effect,” he said.

Those numbers were not included in the presented increases.
