The characteristics and trends of telehealth research in Latin America, especially clinical trials, have been little explored. The objective was to characterize the studies registered in clinicaltrials.gov about telehealth in Latin America. We performed an observational and descriptive study and evaluated the telehealth research in Latin America registered until 2018 in clinicaltrials.gov. The type of study, disease, country, initiative and type of institution were evaluated. We found 37 studies registered. The studies on telehealth were mainly clinical trials of parallel assignment type (81.1%). The most discussed diseases were: Arterial hypertension (23.9%), diabetes (11.3%) and cardiovascular diseases (9.9%). The 64.9% of the works were local initiatives, being Brazil (29.3%) and Argentina (14.6%) the countries with the highest number of investigations. In conclusion, there is a low number of Latin American studies registered in clinicaltrials.gov, the studies focused mainly on chronic diseases and were developed by local initiative. We need more clinical trials on telehealth in the Latin American context to help to consolidate its development.
