Charles R. Drew University of Medicine and Science has agreed to drop a $125-million claim that alleged Los Angeles County breached its contract by halting inpatient services at Martin Luther King Jr./Drew Medical Center. In return, the university will receive county building space under favorable rental terms, a long-term payment schedule for its share of a multimillion-dollar age discrimination lawsuit payout and the ability to forge a new relationship with the county as the Board of Supervisors moves to reopen the hospital.
