Mid-Columbia Medical Center’s extremely low infection rate actually worsened its standing in a new federal program comparing certain hospitals nationwide on complication and infection rates.

MCMC was listed as being in the worst 25 percent of certain hospitals nationwide for hospital-acquired conditions. It was one of 724 hospitals with a poor enough rating that it will have 1 percent of its Medicare payment withheld in this federal fiscal year, which began Oct. 1. That will be about $94,000, hospital spokeswoman Athena Johnston said.
