The Miriam Hospital is a 247-bed community hospital affiliated with the Warren Alpert School Medical School of Brown University in Providence, Rhode Island. The emergency department sees 68,000 visits annually in its 61 treatment spaces, which include 21 lounge chairs for vertical flow. The emergency department has had a long reputation for efficiency and service quality. The ED physicians and staff have always been proud of their performance metrics and empty waiting room. However, after crossing the 60,000-visit volume band, the department began to falter operationally, and its wait times increased. The new normal included an often full waiting room. The emergency department, which effectively operates as a geriatric emergency department (more than 30 percent of its patients being older than age 65), often found itself with Emergency Severity Index (ESI) 2 patients being placed back in the waiting room, a situation that did not please staff.
Hospital President Arthur Sampson and ED Medical Director Gary Bubly, MD, decided to undergo a comprehensive ED operations assessment conducted by an objective third party. The assessment identified opportunities for improvement. The leaders were committed to improving the emergency department but needed a road map of where to start. After the assessment, Dr. Bubly, along with his associate director, Ilse Jenouri, MD, and his nursing counterparts, Denise Brennan, nurse director of emergency services, and Bob Boss, clinical manager, decided to trial a change package with a set of complementary improvements that would commence simultaneously.
Using data, interviews, and observation, the ED operations experts argued that the emergency department had the space and personnel to manage the volumes. Their assessment revealed that intake was cumbersome, with many delays as most steps were conducted in series. Further, though the Miriam emergency department had just begun patient streaming and treating patients in chairs, there was no improvement in wait times because the streaming was not decisive and most geographic zones were mixed-acuity service lines. This made it hard to move low-acuity patients through the system quickly. Other patient flow and housekeeping issues were identified. Using data the leadership team developed, the emergency department implemented the flow model in Figure 1 using the major care/minor care concept used in Great Britain.
