Newswise — In the early 90s, Dr. Jessie Casida was one of few nurses working on the first patient with a left ventricular assist device—a battery-powered device that pumps blood, surgically implanted into the heart of patients who have end-stage heart failure. If the patient is not a candidate for a transplant, they will have the device for the rest of their life.

Now imagine its 1995 and you’re given a paper manual and VCR videos with directions to set up a 2019 printer that will explode if you format it wrong. You have support you can call, and with time, can complete the task, but it’s complicated and stressful because if you make a mistake you could die. And that’s something like the status quo for patients with a left ventricular assist device.

It was this complicated self-management responsibility of the patient that inspired Casida to create VADcare App.

VADcare is a self-management tool for patients with the device. Its prompts them to maintain the device’s functionality, helps them manage their diet, wellness, and medication adherence, lets them evaluate and report abnormal signs, and helps prevent and report complications. The app also includes a system that automatically alerts the patient’s care team when necessary.

The app is still in clinical trial, but all the signs are very promising. An Australian team’s assessment revealed that the app is superior to all other existing self-management platforms for patients with a left ventricular assist device.

“The patients love the app, they don’t want to give it back when the trial is over,” Casida says. 

Casida is an associate professor at the Johns Hopkins School of Nursing.
