Parkland Memorial Hospital has completed 94 percent of the quality and patient safety targets necessary for it to continue receiving federal funding, but the institution continues to struggle in the areas of nurse staffing, timely patient discharges and bedsore prevention, according to a report given to the hospital's Board of Managers Tuesday. Parkland has corrected 469 of 499 problem areas spelled out in a corrective action plan the hospital has been operating under, said Ron Laxton, chief implementation officer and interim chief operating officer for hospital operations. All 499 are supposed to be fixed by April for Parkland to stay eligible to receive about $400 million a year in Medicaid and Medicare reimbursements from the federal government.
