The St. Luke’s Board of Directors Friday approved the proposed affiliation between Kansas University Medical Center and St. Luke’s hospital in Kansas City, Mo.St. Luke’s spokeswoman Kerry O’Connor said that the affiliation is not yet in effect, however, because the final terms – including how much St. Luke’s will pay the university – have not yet been reached.”It means they’ve given permission to St. Luke’s to move forward with finalizing the terms of the agreement,” O’Connor said.Once the terms are agreed to, the agreement would go into effect when both the university and St. Luke’s have signed it. O’Connor could not say whether the action taken Friday meant that further action would be necessary by the St. Luke’s board.
