The iTriage Story

iTriage is a consumer healthcare company founded in 2008 by 2 emergency medicine physicians. Over 9.5 million health care consumers have used iTriage to locate nearby providers based on their symptoms, make appointments, store their personal health record, save medication refill reminders, and learn about thousands of medications, diseases and procedures.

Providers and payers need help to manage costs and quality more effectively, including the help of consumers.  While providers and payers have been working feverishly to improve processes, technology and training, they can’t control consumer behavior.  They need consumers to engage in the system, make good decisions and take action.

In late 2011, iTriage chose to be acquired by Aetna as part of a strategy to significantly alter the way health care is delivered and paid for.  At the time, iTriage had approximately 30 employees, but Mark Bertolini, the CEO of Aetna viewed iTriage as a critical component to achieving Aetna’s goals and strategies.

Starting in late 2011, the White House focused significant attention on iTriage as an example of innovation, growth and impact on the healthcare industry. Since that time, iTriage has been invited back to the White House on multiple occasions, while being repeatedly touted by the CTO of the White House as a leader in effective health care industry change. iTriage has also hosted the White House innovation task force in its Denver office.

Today, iTriage has approximately 115 employees, over 600 hospital partners and thousands of physicians and urgent care partners who all are working to help provide more information and better care to consumers.

About Our Medical Content

iTriage medical content is trusted for its accuracy and relevance. Written by an in-house clinical team of physicians with broad clinical and academic experience, the extensive iTriage medical content has been written with a physician’s general knowledge of a subject compared against multiple established medical resources that vary by medical specialty and subject matter. iTriage content is then condensed and paraphrased for use in the mobile environment. Finally, it is reviewed by one of the most reputable medical institutions in the world – Harvard Medical School.

All diseases and procedures found within iTriage are given International Classification of Diseases (ICD-9) codes, Current Procedural Terminology (CPT) codes and Evaluation and Management (E and M) codes by a Certified Professional Coder.

Along with continual review by Harvard Medical School, the in-house iTriage clinical team routinely surveys published literature to ensure the medical content is current. New health topic suggestions are taken from the broad iTriage user base, as well as from physicians and health care workers using the application around the globe. Content recommendations are sent to iTriage directly via email and through the review process on the iTunes® and Android™ markets. Presently iTriage has more than 60,000 reviews with an average rating of 4.5 out of 5 stars in both market places.

The clinical team compiles the reviews and examines for ideas to develop new content topics and additions for other important metadata. Weekly updates are made to the database and are immediately available on the iTriage Web and mobile versions. Changes to the smartphone applications coincide with software updates, every 6-8 weeks.

Drug information for more than 1,000 of the most commonly used over-the-counter and prescribed medications is licensed from the American Society of Health-System Pharmacists® (ASHSP). These monographs cover 7,500 brand names and contain information on how to use the medication, side effects, drug and food interactions, age-related and disease-related considerations, as well as details about what to do if a dosage is missed or if too much of the medication is taken.

The ASHSP data is updated monthly and these updates include new drug approvals, safety alert information from the FDA’s MedWatch program and revised content based on FDA labeling and therapeutic guidelines. Diseases and procedure images are sourced internally at iTriage by our clinical team. We continue to update the image content on an ongoing basis. Sources for the images were purchased licenses by Shutterstock and iStock photo companies.

Domestic and international copyrights protect all iTriage medical content.
