US hospitals have recovered to pre-recession levels with all classes of hospitals showing positive average margins, according to a new report.

The Thomson Reuters report evaluated the financial performance of 400 US hospitals based on key financial indicators including revenue and profit, employment levels, closures and inpatient volume.

The report shows that the median profit margin of the US hospitals increased from near zero in the third quarter of 2008 to more than 8% in the second quarter of 2009.

The median days-cash-on-hand for the hospitals increased significantly from 90 days in the first quarter of 2009 to 146 days in the second of 2009, higher than the historic long-term average, the report said.

Mean patient discharge volumes for all hospitals declined shortly after the recession started but improved in the second quarter of 2009, the report said.
