Cannon Dr. Relocation to Impact ED Access

Ohio State University is starting a construction project to relocate Cannon Dr. on Sept. 5. Learn more about this project and how it impacts EMS access to the ED.

Traffic Delays Expected Along King Avenue
Beginning Tuesday, Jan. 16, King Avenue lane closures will occur in both directions between Cannon Drive and east of the State Route 315 overpass. The closures will be in place from 9 a.m. to 4 p.m. daily through early February. Two-way traffic will be maintained.

These lane closures will facilitate the installation of a duct bank required for the relocation of Cannon Drive. Traffic delays are anticipated. Beginning early February, once the duct bank installation is complete, intermittent lane closures will occur in the southernmost eastbound lane of King Avenue through the summer as roadway and traffic signal work continue in the area to support the Cannon Drive relocation.

Dates are weather dependent and subject to change. Updates can be found via the Cannon Drive web page.

Important Notice for EMS - Caring for Patients Using Yescarta 

CAR T-cell therapy is a type of Adoptive Cell Therapy – one of the approaches to immunotherapy. The therapy uses a patient’s own white blood cells, modifies them in a lab and retrains them to recognize specific markers on the surface of the cell. The modified cells are infused back in to the patient where they target and kill only those cancerous cells.

On Oct. 18, a drug named Yescarta was approved by the Food and Drug Administration (FDA) for adults with advanced lymphoma. The OSUCCC – James is the only cancer treatment center in Ohio and one of only a few nationwide to offer this new therapy for adults.

Patients who have been treated with Yescarta must undergo specific treatment protocol and should not receive NSAIDS or steroids. Learn more about these patients and their treatment protocol.

The center conducts clinical pre-hospital research, and facilitates interdepartmental research focusing on pre-hospital care, including sudden cardiac arrest and trauma. We also provide opportunities for EMS involvement in clinical laboratories, research and other services throughout Ohio State Wexner Medical Center.

We are currently involved in a variety of research projects, including:

Airway Management

We are spearheading research on identifying the characteristics of paramedics who excel in comprehensive pre-hospital airway management. The research work is funded by a grant that has allowed for the enrollment and assessment of more than 400 paramedics. This research is conducted in The Center for EMS Mobile Simulation Laboratory, placing paramedics in real life, difficult-airway scenarios. With assistance from the Columbus Division of Fire, Worthington Fire Department, Hamilton Township Fire Department, Grandview Heights Fire Department, Genoa Township Fire Department, Westerville Fire Department, Mifflin Township Fire Department, Violet Township Fire Department, and Prairie Township Fire Department, we are able to better understand the educational requirements necessary to become an airway expert.

Ambulance Staffing Patterns

In conjunction with the Columbus Division of Fire, we are evaluating the differences and challenges of utilizing an ambulance team staffed only by paramedics versus a team comprising a paramedic and an EMT. The data will help understand the impact of alternative staffing models in large metropolitan cities.

Evaluation of Pre-Hospital Screening for Stroke Intervention

Recently, three New England Journal of Medicine articles described the benefit of catheter interventions for stroke management that have led to significant neurological improvements for patients with large-vessel occlusive strokes. The Center for EMS, in conjunction with the Central Ohio Trauma System and the Columbus Division of Fire, is seeking to determine whether pre-hospital screening of stroke patients can lead to early identification of patients who may benefit from these catheter interventions.

Increasing Bystander CPR for Cardiac Arrest in High Risk Neighborhoods

Neurologically intact survival of out-of-hospital cardiac arrest is tied to the performance of bystander CPR. However, there are high-risk neighborhoods throughout the United States where bystander CPR rates are low and mortality high. With the assistance of the American Heart Association and a grant from the United Way, we have launched a multicenter trial utilizing the HANDS program, which defines high-risk neighborhoods and teaches CPR through a train-the-trainer model. This novel teaching technique has allowed the community to spearhead the training of CPR within its neighborhoods.

Increasing the Performance of Bystander CPR

Neurologically intact survival from out-of-hospital cardiac arrest is tied to the performance of bystander CPR, but it is unknown what factors motivate bystanders to perform CPR for a stranger or family member. The Center for EMS is conducting research on these factors and whether they are tied to gender, race, education or training (watching a video or taking a class).

Optimizing Pre-Hospital Ventilation

The Center for EMS is also evaluating the relationship between airway management and pre-hospital patient ventilation, with the long-term goal of optimizing patient outcomes through improved oxygenation and perfusion. This research also is conducted in The Center for EMS Mobile Simulation Laboratory, which places paramedics in real life, difficult-airway scenarios.

Pre-Hospital Therapeutic Hypothermia

Due to changing paradigms for the use of pre-hospital therapeutic hypothermia, the Center for EMS became concerned about the safety of this intervention in our community. In conjunction with Columbus Division of Fire, we have evaluated the outcomes and complications of patients who suffered out-of-hospital cardiac arrest and received therapeutic hypothermia. The first study in this area was recently published in Prehospital and Disaster Medicine.

Tele-EMS Medical Direction

Critical-care transports of acutely ill patients are highly challenging and may require time-sensitive treatments for the best patient outcome. The Center for EMS, with MedFlight of Ohio, is working on delivering specialized medical direction to the EMS bedside through the use of Tele-EMS, essentially allowing physician specialists to be in the back of ambulances with critical care teams through real-time video feeds. The physicians can even to listen to the heart and lungs while the ambulance is en route and can direct medical care for the patient.

Heartmobile Project

The Ohio State University Wexner Medical Center is a pioneer in developing Emergency Medical Services. In 1969, Dr. James Warren, a Ohio State physician, initiated the Heartmobile project in cooperation with the Columbus Division of Fire. Warren demonstrated that patients could be successfully resuscitated from cardiac arrest in an out-of-hospital setting. He went on to demonstrate that firefighters could be trained in advanced resuscitation techniques.

The Center for EMS is dedicated to maintaining our tie to this important piece of Columbus and national history and is a major contributor to the Heartmobile project, focused on the restoration of this landmark.
