Objective: To analyze the use, effectiveness, and resolubility of teleconsultation services provided to primary care units by the Telehealth Network of Minas Gerais, a public service providing teleconsultation and telediagnosis in cardiology to 821 health care sites.
Methods: This observational retrospective study included teleconsultations carried out between April 2007 and December 2012. Teleconsultations performed from January to May 2010 and January to March 2012 were analyzed regarding the type of query asked by professionals using the service. A survey was carried out to evaluate resolubility and level of satisfaction with teleconsultations.
Results: During the study period, 47 689 teleconsultations were carried out. They were most often requested by nurses (53.2%) and physicians (34.3%), and were answered mainly by the following professionals: family physicians (23.3%), dermatologists (19.8%), gynecologists (10,7%), internal medicine physicians (8.8%), pediatricians (6.6%), and nurses (12.2%). The median population in the municipalities that requested teleconsultations was 6 778 (interquartile range [IQR]: 4 425 - 10 805). The median human development index (HDI) was 0.645 (IQR: 0.577 - 0.690). The most frequent queries regarded pharmacological treatment, non-pharmacological treatment, and etiology. Teleconsultations prevented potential referrals in 80% of the cases, and 94% of the health providers reported satisfaction with the service.
Conclusions: The results show that the Telehealth Network of Minas Gerais can help overcome physical barriers in the access to health care and that it may be an important and effective tool for continued health education.
