Johns Hopkins Howard County Medical Center Emergency Room (ER)

ER Exterior Entrance

Our 36-bed Emergency Room is staffed 24-hours a day, seven days a week by board-certified Johns Hopkins emergency medicine physicians. The 24,000 square foot expansion provides state-of-the-art comprehensive, individualized emergency medical care and urgent care to the citizens of Howard County and the surrounding area.

Read our quick-reference guide for advice on when you should go to the Emergency Room.

What to Expect Upon Arrival

  • After the triage nurse completes your assessment, you will be escorted to a treatment area when one is available.
  • In order to expedite your care, we may immediately initiate some tests before you are taken to the treatment area.
  • Please notify us right away if you feel that your condition is worsening.


Your medical care is our first priority. To best meet your needs, our registration process has two stages. You will be asked to complete a brief registration upon arrival and provide a photo ID. If you have been treated here before, this will help us access your existing medical records to ensure we have the critical information.

Once you have been seen by a member of the care team, an admission counselor will meet you to complete your registration, including gathering insurance information and signing consent forms.

Wait Time

ER Front Desk

Unfortunately, there are times when the number of patients seeking care exceeds the number of treatment spaces. During those times, we must prioritize who is brought to the treatment area based on their individual situation and the treatment areas which are available. Pediatric patients will be moved to our special Pediatric Emergency Department. We also have a rapid evaluation process for less complex conditions.

Triage & Treatment Priority

Following our evaluation, patients are prioritized based on individual medical need, not solely by the time of arrival.

Evaluation / Treatment Time

Depending on your condition and symptoms, a variety of tests may be needed. The results of some tests, including blood work or diagnostic studies, can take a few hours to complete. If you have questions about how long something is going to take, please ask your care provider.

Your Care Providers

An emergency physician or physician assistant, who works under the direct supervision of our emergency physicians, and our emergency nursing staff will care for you. Depending on your situation, a specialist also may be contacted to come to the hospital to evaluate and treat you.


We work collaboratively with our community medical providers. If your physician’s office has referred you, please let us know. Any information provided by their office helps guide us in deciding what testing you may need. Whether you were referred or arrived independently, we provide all patients with assessment testing and care based on our evaluation of your current condition.

Follow-up Care

We will care for your emergent condition today. However, to ensure you receive the highest level of ongoing treatment, we may recommend that you follow up with a medical provider after your Emergency Room visit. If you do not have a regular medical provider we would be happy to provide you with a referral.

Behavioral Health Navigators

Two Emergency Department staff members are helping to meet an important need in the Howard County community - coordinating follow up care for behavioral health patients. Johns Hopkins Howard County Medical Center's behavioral health navigators are working with patients with behavioral health needs and their family members by providing information, resources and referrals to services in the community, such as mental health treatment, substance use treatment, support groups and house based programs.
