ST. PETERSBURG, Fla. — Johns Hopkins All Children's Hospital has submitted a corrective action plan after it parted ways with numerous high-profile staff members in the wake of a Tampa Bay Times investigation that exposed problems in the facility's heart surgery program.

The plan was turned in Sunday, just before the deadline.

An outside law firm has been hired to spearhead the investigation into what went wrong.

Several medical errors were found during a January inspection. Those included quality and infection control issues.

The federal government threatened to cut funding if the hospital did not act. If that happened, the hospital won't be eligible for Medicare payments.

"We take these findings seriously and are continuing to work in close coordination and consultation with both AHCA and CMS to immediately address their concerns," a spokesperson for Johns Hopkins Medicine wrote in an email.

The corrective action includes governance shake-ups, new physician credentialing measures and alterations to quality improvement planning and infection control. 

"The safety of our patients is our top priority," the spokesperson said. "We are confident in the work we are doing to ensure that our hospital continues to meet the highest standards of care."
