Mayo Hospital Emergncy Department Patient Room

Mayo Regional Hospital's new Emergency Department opened in May, 2002. The department is connected to the patient registration area off the main lobby of the hospital. It has a separate walk-in entry for pedestrian traffic and a canopied, two-bay ambulance entrance. It is conveniently located just around the corner from Radiology and Cardiopulmonary Services. An elevator connects the department directly to the Medical/Surgical Unit on the hospital's second floor.

The Department has a private triage area and nine treatment rooms, including special facilities for orthopedic patients, trauma and critical care, cardiac care with monitoring, and routine visit care. There is a spacious and sunny waiting area for families. The department is organized around a central nursing station, where staff are only a few steps away from any patient at all times. Most rooms have a television that can be used by patients and their families when waits are needed for tests to be processed in the laboratory or radiology.

Emergency Department Provider Staff:

Mayo's Emergency Department is staffed 24 hours a day, every day, as we respond to over 13,000 patient visits annually. The clinical teams are led by physicians and physician assistants who have special training in Emergency Assessment and Care. The members of the medical staff of Mayo Regional Hospital are on call for the department in every specialty available at the hospital for consultation, if needed. In addition, we have a direct video conference link for trauma patients with the trauma surgery team at Eastern Maine Medical Center which can bring the eyes and ears of their trauma surgeons right into the examination room here when we need their guidance and support.

David B. McDermott, MD, MPH, a family practice physician who has worked at Mayo Regional since 1993, is medical director of the Emergency Department.

Emergency Department Nursing Staff

The Emergency Department is staffed with a full complement of Registered Nurses (RNs). Many have specialty certification in Emergency and Trauma Nursing. All are trained to provide care to adult, geriatric or pediatric patients.

Valerie Philpot, RN is the department's nurse manager.

Unit Coordinators

These folks are truly special. They are the counter clerks you see at the desk upon arrival. They do every thing that has to do with the paper and records, plus answer phones, contact physicians, coordinate care with the laboratory, find your old medical records, arrange for radiology tests and log patients in and out of the department. They are the unsung heroes of the department.

For Your Safety

Many patients have more than one provider involved in their care. We ask that you bring with you to the department every medication you are now taking, including over-the-counter medicines, vitamins, and supplements. It is critically important that we know the specific medications you take and the doses of them. No list is a substitute for seeing the actual bottles. If you don't know what you are taking and why you are taking it then we won't know what you are taking, and this can become a dangerous place for you when your own health status on the line. This is an important step you should take for your own protection

We see a number of patients with acute pain. Every attempt will be made to provide you with resources to help you cope with the pain that your condition brings to you. However, Emergency Departments are often used by people with narcotic and other addictions to gain access to medications for purposes other than treatment, including abuse and diversion (selling to others). We use a number of tools to assess risk for this in the department, including coordination with your primary care physicians, reviewing old records, and checking the Prescription Monitoring Program run by the State of Maine for patterns that might support prescription drug overuse or abuse.

Violence is becoming an increasingly accepted part of life in our complex society. We want our department to be a place of healing from injuries. The department is locked to control access at all times. We do ask that you leave any potential weapons (knives, guns, or concealed weapons) secured in your vehicle before you enter the department for care or to visit your loved ones. Our staff members are here to help and to heal. Because of this we will not tolerate violence or threats of violence against our staff or the facility. Aggressive and/or violent behavior by patients or their visitors will not be tolerated, and may lead to involvement of local law enforcement.

What to Expect During Your Visit to Mayo Regional Hospital

Our Emergency Department (ED) is a constantly changing place. Sometimes it is quiet and steady as patients come through with minor illnesses and injuries. Other times, our department is alive with action as emergency care experts pull critically ill or injured patients from ambulances -- and try to save lives. No matter how busy we may be, the ED is always open, and the people who work here are always prepared to care for all types of emergencies.

Learn what to expect during a visit to the ED in terms of wait times, triage, visitors, diagnosis, and the team approach to care.

Wait Times

Like emergency departments around the nation, our ED sometimes gets overcrowded. We do our best to treat patients as soon as possible, but sometimes there is a wait. Even though we try to work as quickly as we can, we must always take the time we need to make sure our patients are safely cared for. How fast you are seen depends on “acuity” which describes how urgent a patient’s needs may be, as determined by a system we call “triage”.


Patients who do not require immediate, life-saving action from a doctor or physician assistant may first be sent to the triage room, where nurses evaluate their vital signs, and patients are interviewed about their condition. If a bed is available, the patient will be moved to a room at that time. If there is no bed available, the patient will be moved to the waiting room. Once you have been seen by the triage nurse, you appear on our “tracking board” so we can see who should be seen next, according to “acuity” and time of arrival. Patients who arrive with serious or potentially life-threatening conditions may be taken directly to the ED treatment area and will be seen immediately by nurses and/or medical staff.


Patients can choose who can visit them while they are in the ED. Once patients are in an exam room, they may ask their nurse to bring their visitors to that area. ED staff may limit the number of visitors based on patient safety and patient care needs.


After obtaining information about a patient, the emergency provider does a physical examination to determine an appropriate diagnosis. If a diagnosis cannot be determined from the examination and other available information, the provider may order tests, such as X-rays or blood tests. In difficult cases, the provider may talk with other specialists to determine an appropriate diagnosis and further course of action.

Team Approach to Care

Patients are cared for by both nurses and medical team members in the department. Our unit coordinators work to manage records and ensure that the department runs smoothly. Other health team members such as laboratory or radiology (X-Ray) staff may be involved in patient care. Mayo Regional Hospital is committed to making sure that all team members talk with each other to provide our patients with the best and safest care possible.
