 Kate Ryan, WTOP News. The sizzling hot weather has driven some patients to the hospital emergency room. We broke another one-day record today. It was 101 at least at DCA. That was a record for the day. WTOP's Dick Uliano reports the extreme heat has sparked an uptick in emergency room visits. Dr. Neil Roy, chief medical officer and emergency room physician at Shady Grove Adventist, says hospitals are seeing an uptick in the number of patients with heat-related illness.
