Use of Internet/Application-Based E-consults by General Practitioners in Japan to Resolve Patients’ Problems: A Descriptive Observational Study

Introduction Electronic consultations (e-consults) refer to digital health technologies that enhance clinical information sharing and improve patients' access to expert healthcare providers. This study aims to describe the current utilization of the Internet/application-based e-consult system and to assess how effectively it resolves clinical questions. Methods Participants were general practitioners (GPs) who had installed the e-consult platform on their personal computers or cell phones. Hospital specialists who responded to the e-consults were previously registered on our e-consult platform and also participated in the study. We have developed and implemented an Internet/application-based e-consult system that GPs can use on their personal computers in Japan. In this descriptive study, GPs used the e-consult platform via an Internet/application to consult hospital specialists. The study period was from May 1, 2020, to October 31, 2021. The outcome measure was the resolution rate, calculated by dividing the number of cases resolved solely through e-consults by the total number of e-consult cases. Another outcome measure was the number of cases in which a plan was determined using e-consults. Other outcome measures were GP satisfaction, assessed using a 5-point Likert scale for e-consults, the number of chats required for a hospital specialist to respond, and the time from the GP's initial question to the hospital specialist's first response. Results Of the 329 e-consult cases identified, 91 conducted by GPs were included in the final analysis. The number of cases resolved using only e-consults was 47, resulting in a resolution rate of 52% in the study. The minor specialists exhibited the highest resolution rate using e-consults alone. The number of cases where a plan was determined using e-consults was 83, accounting for 91% of the total 91 cases. The level of GP satisfaction with the e-consult process was high, with a median satisfaction score of 5 on a 5-point Likert scale. Most e-consults received their initial response within two hours. The number of chats required for hospital specialists to respond was very low, with a median of only one chat being necessary. Conclusion The Internet/application-based e-consult system enabled GPs to address a wide range of medical problems. Further studies with large samples are necessary, even though these results serve as an important benchmark for future research on e-consults in Japan.
