Emergency rooms in Massachusetts are more crowded than ever before, according to local doctors.Dr. Jason Tracy, chief of emergency medicine at South Shore Health in Weymouth, said volumes at his ER are the worst they’ve ever been.”We have about 70 beds in our emergency department and, right now, there’s approximately 120 patients,” Tracy said.Other Massachusetts hospitals, such as UMass Memorial Medical Center in Worcester and Tufts Medical Center in Boston, are seeing similar surges. Tracy said COVID-19 is just one of many factors playing a role in the record-high emergency room capacities.”It’s trauma, strokes, heart attacks, regular viral illnesses, pneumonia. It’s pretty much everything, but it’s just a larger volume than we normally see,” Tracy said.Hospital officials say COVID-19 infections are continuing to reduce emergency room staffing, which is adding to wait times in the ER.Tracy said some patients who visit an emergency room could instead go to an urgent care center or see their primary care physician.”The emergency room really should be used for those conditions where time is of the essence,” he said.Sherri Grankewicz, a patient who visited the ER at South Shore Hospital on Wednesday, said she was still waiting to receive tests seven hours after she arrived.”I don’t feel very good about it at all,” Grankewicz said. “It’s very disconcerting. It’s really disconcerting.”Tracy and other doctors are unsure about when the long waits at emergency rooms will subside.”We just don’t know, so we are continually preparing for what’s to come,” Tracy said.
