Sixty seconds can make or break the result of the “blue hospital code” or cardiac arrest response. New research finds that a hospital code response team rushing to a cardiac arrest patient may arrive at least one minute faster and may also lead to better patient outcomes using a smartphone emergency code notification system that activates the team through text messages. The results are preliminary research that will be presented at the American Heart Association Resuscitation Science Symposium 2022. The 2022 meeting will take place in person in Chicago, November 5-6, 2022, and will include the latest advances in the treatment of cardiopulmonary arrest and life-threatening traumatic injuries.

Cardiac arrest is a condition in which the heart’s electrical system malfunctions and stops beating. Previous studies looking at ways to reduce in-hospital cardiac arrest have focused on early treatment, including defibrillation and epinephrine administration to improve patient outcomes.

Most hospitals have a code team consisting of a specially trained and designated team health professionals Which revives patients when they are in cardiac arrest. Activation of the code team usually begins with a call to the hospital operator who sends a page to the code Team members Sometimes the hospital-wide top page is called “Code Blue”. There is often a delay from the time someone recognizes that the patient has no pulse until team members receive the blue page code. Code team members are usually different from the medical team that primarily cares about the patient and may not know the patient or have information about their health conditions or treatments.

In this study, researchers at the University of Maryland Medical Center in Baltimore discovered how to improve outcomes and target patient treatments by accelerating notification of the code care team. They electronically assigned the blue code buttons behind each patient bed to a secure smartphone text messaging system that also links to the hospital’s electronic medical records. Pushing the button sends important patient data, such as admission diagnoses and lab details, to team members’ smartphones. At the same time, the blue code button contacted the hospital operator who activated the code team through traditional methods, including overhead pages and call alerts. The researchers then compared the differences in smartphone text message activation to the traditional code-top page announcement, how long each method took to give epinephrine to a patient, and the patient’s survival rate to hospital discharge.

In this analysis of 35 cardiac arrest events over a three-year period, from November 2019 to May 2022, using a smartphone notification system, code team activations were nearly instantaneous with notifications received immediately via text message. The traditional methods of activating the code team took an average of 78 seconds, which means that activating the smartphone cuts off the notification by more than one minute.

Study lead author Cody Couperus, MD, said: Resident doctor In the Emergency Medicine and the Internal Medicine Program at the University of Maryland Medical Center in Baltimore.

“Improving notification processes can get code teams to the patient faster, equipped with patient knowledge that may lead to targeted therapies that resuscitate the patient more efficiently,” he said. “Time is of the essence, and the sooner a patient is treated for an underlying cause, the more likely they are to survive without a serious brain injury. In the future, we hope to show that code teams arrive faster using this blue smartphone icon notification system and that more patients stay on surviving without severe brain injury.”

Other results included:

  • Smartphone code blue notification was the primary mode of code team activation for more than one-third of cardiac arrest events during the 3-year study period.
  • The median documented time to administer epinephrine for notifications was 3 minutes after the arrival of the code team with smartphone activated versus 4 minutes with the standard notification system.
  • Survival to hospital discharge was 25% for cardiac arrest events relative to notifications activated with smartphone activation, compared to about 17% when cipher The team is activated with the standard Attention the system.

Among the limitations, the researchers note that the small number of patients in the study makes it difficult to draw statistically significant conclusions about the effects of smart phone Turn on the activation system Patient resultsFurther studies involving larger groups of participants are necessary to assess the effect.

“Healthcare professionals need to be strong advocates of quality initiatives to improve rapid recovery of patients with heart stop In our hospitals, Coupros said. “Outcomes after pulse loss in hospital have remained largely stable and weak over the years, and these findings suggest that technological innovations may help us do better.”
