Details and patient eligibility


Healthcare delivery now mandates shorter visits with higher documentation requirements, undermining the patient-provider interaction. Electronic health records (EHRs) have the potential to improve outcomes and quality of care in this pressured environment, and are endorsed by the Patient Protection and Affordable Care Act (ACA) and Health Information Technology for Economic and Clinical Health (HITECH) Act as an important mechanism to support value-based healthcare. However, EHR systems were principally designed to support the transactional needs of administrators and billers, less so to nurture the relationship between patients and their providers. The purpose of this research is to identify ways to use EHRs to support clinical gastroenterologists and their patients while meeting the meaningful use requirements of the HITECH Act. To improve clinic visit efficiency and meet criteria for meaningful use, investigators developed a patient-provider portal (P3) that systematically collects patient symptoms using a computer algorithm called Automated Evaluation of Gastrointestinal Symptoms (AEGIS). AEGIS utilizes computerized adaptive testing (CAT) to guide patients through questions drawn from a library of over 300 symptom attributes measuring the timing, severity, frequency, location, quality, and character of their GI symptoms, along with relevant comorbidities, family history, and alarm features. The system then automatically "translates" the patient report into a full narrative HPI available for use by GI providers in an EHR. In a cross-sectional study in the American Journal of Gastroenterology comparing AEGIS versus physician-documented HPIs, investigators found that blinded physician reviewers perceived that AEGIS HPIs were of higher overall quality, better organized, and more succinct, comprehensible, complete and useful compared to HPIs written by physicians during usual care in academic GI clinics. In the current study, investigators aim to evaluate computer-generated HPIs prospectively on a wider scale in diverse academic and community-based settings. Moreover, investigators aim to test an enhanced AEGIS intervention that ties patient HPIs to an individualized "education prescription" which guides the patient through a library of multi-media educational materials on GI symptoms, conditions, and treatments.

No Intervention group
Individuals in this arm will undergo usual care with their physician.
AEGIS (Automated Evaluation of Gastrointestinal Symptoms)
Experimental group
Individuals in the AEGIS arm will be invited to use AEGIS/My GI Health prior to their clinic visit. For those who complete AEGIS/My GI Health, their physician will have access to their AEGIS symptom report (includes a GI symptom heat map and GI history) and tailored education prescription.
