What to Expect When You Arrive at the ER

Step 1: Check-In and Registration

Upon entering the McLaren Greater Lansing Emergency Department, you will be greeted by a triage nurse who performs a rapid assessment to determine the severity of your condition. This is not first-come, first-served — it is acuity-based. Life-threatening symptoms (chest pain, difficulty breathing, stroke signs) are prioritized immediately.

• Bring your photo ID and insurance card if available.
• List your current medications — a pharmacy bottle photo works if you do not have the list handy.
• Provide a contact name for the hospital to reach a family member or caregiver.
• If you are unable to register yourself, a companion or ER staff can assist with registration.

Step 2: Triage Assessment

The triage nurse measures vital signs, reviews your chief complaint, and assigns an Emergency Severity Index (ESI) rating from 1 (most urgent) to 5 (least urgent). Understanding this ranking helps set realistic expectations about wait times.

• ESI Level 1: Immediate life-saving intervention required — seen within minutes.
• ESI Level 2: High-risk situation or severe pain — seen within 10–15 minutes.
• ESI Level 3: Potentially serious — seen within 30–60 minutes.
• ESI Level 4: Stable but needing emergency care — wait may extend to 1–2 hours.
• ESI Level 5: Non-urgent — wait can exceed 2 hours; consider an urgent care alternative.

Step 3: Evaluation and Treatment

Once called back, you will be assigned a treatment room or cubicle. An ER physician or physician assistant will evaluate you, order diagnostic tests (labs, X-rays, CT scans), and begin treatment. A nurse will remain your primary point of contact throughout your stay.

• Ask the nursing staff about estimated wait times for test results.
• You have the right to request an interpreter at no cost.
• One companion is typically permitted in the treatment area; pediatric and sensitive cases may allow additional supporters.

Step 4: Discharge or Admission

At the conclusion of your visit, you will either be discharged with follow-up instructions or admitted to the hospital for continued inpatient care. Discharge paperwork includes medication instructions, warning signs to watch for, and recommended follow-up appointments.

• Request a printed copy of your discharge instructions before you leave.
• Confirm the timeline for follow-up with your primary care provider or specialist.
• Ask about prescription details — including dosage, timing, and where to fill it.
• If admitted, ask the ER physician to communicate directly with the admitting team to avoid duplication of tests.
