The article about Kenneth Samet replacing Dunlop Ecker as president of the Washington Hospital Center {Metro, Nov. 3} correctly identified Medlantic Healthcare Group as the city's largest health care provider, with three hospitals and 11 other health care facilities. However, the unnamed source who indicated that the hospital center had transferred $80 million to Medlantic is in error.

According to the auditor's report cited in the article, the center transferred $65 million, of which $12 million was spent on the hospital center's new computer center and medical research activities. Another $15 million of the $65 million remains in cash. The remainder, $38 million, was used to create the nonprofit Medlantic Healthcare Group, including the National Rehabilitation Hospital, two nursing homes, a med-care center, an ambulatory surgery center, an alcohol treatment center and the Visiting Nurse Association. Last month, ground was broken for the new Cancer Institute at the hospital center.

Although the doctor quoted in the article feels the hospital center has suffered, it is the view of many that the creation of a vertically integrated health care network is the best means of preparing for the financial difficulties of the '90s. Changing realities in the health care world call for changing strategies in providing quality care.
