ST. JOSEPH, MI — People heading to a Michigan emergency room can expect to spend roughly three hours there, based on new federal data covering visits from July 2024 through June 2025.
The statewide median ER stay was 3 hours, 14 minutes, which puts Michigan 19th among the 50 states for length of emergency-department visits. In Southwest Michigan, Corewell Health Lakeland Hospital in St. Joseph reported a shorter median of 2 hours, 38 minutes.
The figures come from a nationwide analysis of more than 4,000 hospitals and 137 million emergency-department visits. FindEMR, a healthcare technology research site, examined hospital data from the Centers for Medicare & Medicaid Services.
Michigan’s median sits near the middle of the national pack
Michigan’s 194-minute median puts the state toward the longer side nationally, but not near the top. The slowest median time in the country was recorded in Maryland at 4 hours, 17 minutes, while South Dakota had the shortest at 2 hours, 17 minutes.
Neighboring states also fell on both sides of Michigan. Ohio’s median ER stay was 3 hours, 1 minute, while Wisconsin’s was 2 hours, 41 minutes. Illinois ranked higher on the time scale, with a median of 3 hours, 34 minutes.
Because the number is a median, it reflects the midpoint rather than the average. Half of the recorded visits were shorter, and half lasted longer.
Hospital-to-hospital differences are wide across the state
The statewide figure hides major differences from one Michigan hospital to another. Among the 118 hospitals included in the state analysis, median emergency-department stays ranged from just 1 hour, 2 minutes to nearly six hours.
The longest median visit in Michigan was reported by the University of Michigan Health System in Ann Arbor at 5 hours, 58 minutes. At the opposite end, Sheridan Community Hospital had a median of 1 hour, 2 minutes.
That spread shows how much local staffing, case mix and patient volume can influence how long people remain in the emergency department. A single state number can give a broad picture, but it does not tell the whole story for every hospital.
St. Joseph’s ER comes in below the state mark
Corewell Health Lakeland Hospital in St. Joseph posted a median ER visit of 158 minutes, or about 2 hours, 38 minutes, for all emergency-department patients. That is 36 minutes faster than the Michigan median.
For patients who were discharged and were not transferred to another facility or receiving psychiatric or mental-health care, the St. Joseph median was 157 minutes. Corewell Health says the St. Joseph emergency department has 75 patient rooms, including four dedicated trauma bays.
The health system’s Niles hospital also operates a 24-hour emergency department with 23 rooms. Those facilities serve patients whose needs can range from minor injuries to urgent, life-threatening conditions.
Emergency departments treat the sickest patients first
Wait times in an ER do not follow a simple first-come, first-served pattern. Patients with the most serious conditions are treated first, which means someone who arrives later may be seen sooner if their need is greater.
That triage system helps emergency teams focus on the patients in the most critical condition. It also means a relatively straightforward injury or illness can turn into a longer wait when the department is dealing with trauma, admissions or other emergencies.
For families and older adults especially, that distinction can be important. A longer stay does not automatically signal a problem with care; it may reflect the way emergency rooms prioritize the sickest people first.
Mental-health crises keep patients in the ER much longer
The most dramatic gap in the Michigan data involves patients arriving in mental-health crisis. Their median stay in a Michigan emergency department was 5 hours, 20 minutes, which is more than two hours longer than the statewide median for all patients.
That difference works out to 2 hours, 6 minutes. Researchers say the gap may reflect the extra resources needed for psychiatric emergencies and the availability, or lack, of appropriate mental-health services outside the emergency department.
The pattern is not unique to Michigan. National data show similar differences from state to state, underscoring how emergency departments often become the default setting when community mental-health options are limited.
A small share of patients leave before being seen
Federal data show that about 2.7% of Michigan emergency-room patients leave before they are seen by medical staff. That works out to roughly 27 out of every 1,000 ER arrivals.
At Corewell Health Lakeland Hospital in St. Joseph, the comparable figure is 2%, according to the CMS data. Those numbers do not necessarily mean those patients had serious emergencies; ERs also see people with problems that might be better handled in urgent care or by a primary-care doctor.
Still, the statistics highlight the pressure emergency departments face when patient numbers and severity levels shift quickly. For Michigan residents, the takeaway is simple: a three-hour ER visit is close to the statewide norm, while St. Joseph’s median is somewhat shorter.
