Of the respondents participating in medical alliance service, 41.8% and 16.8% considered that the service resulted in generally good and good effect; 50.6% and 49.4% regarded procedure management of two-way referral and patients′ demand for telemedicine as the main problem in the operation of medical alliance. Among the respondents not participating in medical alliance service, 41.4%, 28.9%, 21.1%, and 8.6% attributed the nonparticipation to not having time to participate due to busy work, disagreeing the necessity of medical alliance service, not having opportunity to be involved in the service, and not having been informed by administrative department.
