To meet patient demands for comfort and to keep them happy in an increasingly competitive market, Boston-area medical institutions, including Newton-Wellesley Hospital and Beth Israel Deaconess Hospital-Needham, have recently completed renovations that add more private inpatient rooms. Joe Kirkpatrick, senior vice president for healthcare finance and managed care at the Massachusetts Hospital Association, told the Boston Globe that many healthcare centers in the state have begun reinvesting in their infrastructure in recent years after a long dry spell between 1995 and 2005.
