Jane Cline, a former state insurance commissioner, now works for the HMO Association, which represents the managed care companies.
She said the three companies do use the Delmarva reviews to make changes. She said the state also uses them, even if DHHR officials didn't make that clear to the Legislature several weeks ago.
"The report is the actual tool that is used by (Medicaid) to monitor and improve MCO performance," Cline and fellow lobbyist Mary Jane Pickens said in a statement on behalf of the association.
The performance of the companies is under particular scrutiny now because the state is preparing to turn over the care of 57,000 elderly or disabled Medicaid patients to them, giving each company a larger portfolio than they have now.
The plan, which was delayed from late this year until next summer, is expected to help the state save money. Critics of managed care have questioned whether DHHR has carefully thought out the plan.
In its latest report, Delmarva gave the companies mixed reviews.
An analysis of the Delmarva report by West Virginians for Affordable Health Care found the companies were getting results below the national average in nine categories but were getting above-average results in a dozen categories.
Cline and Pickens said a careful review of the report shows the companies have been successful in encouraging preventative measures.
"They encourage visits and screenings, but patient compliance with the physician's treatment recommendations including lifestyle changes is more difficult," the pair said.
