PEER-REVIEWED STUDIES
Using AI-based virtual triage to improve acuity-level alignment of patient care seeking in an ambulatory care setting
Gellert et al. (2024) / International Journal of Healthcare
A study evaluating the impact of AI-based virtual triage (VT) on patient care-seeking behavior in an outpatient care setting. Researchers analyzed 8,088 online encounters to understand how VT influenced patient behavior regarding care levels.
Highlights
35% of patients changed their care-seeking behavior
12.5% decrease in video and in-person consultations
19.1% increase in patient engagement through virtual care
The results show how VT helped reduce unnecessary in-person visits, streamline care delivery, and ensure patients received suitable care, potentially improving overall healthcare efficiency in ambulatory settings.
The potential of virtual triage AI to improve early detection, care acuity alignment, and emergent care referral of life-threatening conditions
Gellert et al. (2024) / Frontiers in Public Health
A study evaluating the extent to which users intended to seek emergency care when reporting symptoms of five severe/acute conditions to a virtual triage (VT) engine. The five conditions in question have high potential mortality; heart attack, stroke, asthma, pneumonia, and pulmonary embolism (PE). The study highlights misalignments between perceived seriousness and the actual risk of life-threatening symptoms and how VT could be used to address this.
Highlights
76% of users with symptoms of a heart attack didn't plan urgent care help
33.5% of users with symptoms of investigated acute conditions hadn’t planned medical consultation before completing virtual triage
2 in every 1000 virtual triages performed could lead to life-saving decisions
Early detection of emergency conditions can significantly reduce the risk of severe health outcomes and death. This study shows the strong influence of VT on modifying care-seeking behavior, which could result in reduced healthcare expenses due to timely intervention.
A comparative performance analysis of live clinical triage using rules-based triage protocols versus artificial intelligence-based automated virtual triage
Gellert et al. (2023) / Journal of Hospital Administration
A comparison of the triage care referral accuracy of AI-based virtual triage to rules-based triage protocols (RBTP). The study concludes that Infermedica’s AI tools perform comparably to the Schmitt-Thompson protocols — the industry gold standard for patient triage.
Highlights
Infermedica and Schmitt-Thompson produced zero critical mis-triage situations — cases where an “emergency” is identified as “self-care”
Infermedica provides triage advice as safe as Schmitt-Thompson
Infermedica collects 4x more patient initial symptoms than Schmitt-Thompson for more data-driven assistance
Infermedica provides reliable and accurate results and increases triage levels in case of risk factors (especially for children)
How Virtual Triage Can Improve Patient Experience and Satisfaction: A Narrative Review and Look Forward
Gellert et al. (2023) / PubMed Central (PMC), National Institutes of Health (NIH)
Review and synthesis of the literature on patient experience and satisfaction as informed by emerging evidence, indicating potential for virtual triage (VT) to favorably impact these clinical care objectives and outcomes.
Highlights
Delivery of earlier and faster, more acuity-level-appropriate care
Digital triage as a front door to reduce a patient’s need to visit a medical facility for low-acuity conditions
The use of VT to enhance clinical effectiveness through early detection and referral
VT as an opportunity for providers to make patient health care experiences more personalized
The Role of Virtual Triage in Improving Clinician Experience and Satisfaction: A Narrative Review
Gellert et al. (2023) / PubMed, National Institutes of Health (NIH)
A review and synthesis of evidence on clinician satisfaction indicating a potential for virtual triage (VT) to favorably impact clinician experience, sense of effectiveness, efficiency, and reduction of administrative task burden.
Highlights
Importance of clinician experience and satisfaction to organizational performance
Contributors to poor clinician satisfaction
Current and potential role of virtual triage in delivering positive clinician experiences and streamlining communication with patients
Benefits of using virtual triage technology for healthcare delivery organizations in general and with respect specifically to improving clinician experience and satisfaction
Cardiovascular Disease Prevention Recommendations From an Online Chat-Based AI Model
Gellert, G. A., & Jaszczak, J. (2023) / Journal of the American Medical Association (JAMA)
A response to a recent report discussing how a dialogue-based AI model can assist clinical workflows. The comment and subsequent response from the authors address the safe use of AI and large language models (LLMs) in healthcare.
Highlights
Generative AI vs. Symbolic AI in healthcare applications
Potential and limitations of large language models (LLMs)
Investment and research into healthcare AI
A Multinational Survey of Patient Utilization of and Value Conveyed through Virtual Symptom Triage and Healthcare Referral
Gellert et al. (2023) / Frontiers in Public Health
A study based on an online survey of 2,113 web-based patient-users of Symptomate to describe the use patterns, impact, and derived patient-user value of a virtual triage/symptom checker.
Highlights
80.1% of patients indicated substantial overall satisfaction with the experience and value delivered
80% of users indicated that they will use triage recurrently in the future
25.4% decrease in post-triage patients who remained uncertain of their care path
The quality of diagnosis and triage advice provided by free online symptom checkers and apps in Australia
Australian Department of Education, Skills and Employment
This Systematic Performance Case Study presents the investigation of 36 symptom checkers providing a medical diagnosis or triage advice, where each was tested with 48 medical condition vignettes (1,170 diagnosis vignette tests and 688 triage vignette tests).
Highlights
Symptomate has the highest accuracy results:
77% correct possible conditions listed in the top 3 results
61% correct possible conditions listed as first
81% correct possible conditions listed in the top 10 results
