Through technological innovations based information and communication technologies (ICT), advantageous telediagnostic systems can be developed to improve the health care of remote populations (1). In the context of universal coverage and the efficient use of available resources, there is a favorable opportunity to develop telemedicine towards an integrated ecosystem to improve health care in remote locations without access to specialists. This study, performed by the Telemedicine Unit (MoH) in collaboration with the Biomedical Engineering Dept (IICS-UNA) and the Basque Country University (UPV/EHU) evaluated a telediagnostic system implemented in 2014 in public health. The results of a cost utility analysis for this telediagnosis project in remote, regional and district hospitals in Paraguay are presented.

This is a prospective study, where the results of using telediagnosis implemented in remote hospitals over three years 2014–16 were evaulated. For these purposes, a utility analysis was carried out by comparing the cost of performing telediagnosis versus performing it “face to face” in a diagnosis center in the capital city.

During the study 182,406 remote diagnoses were performed in the fifty-four remote hospitals using the telediagnosis tool. Of the total, 37.3 percent (68,085) corresponded to tomography (CT), 62.0 percent (113,059) to electrocardiography (ECG), 0.68 percent (1,243) to electroencephalography (EEG) and 0.01 percent (19) to ultrasound studies. The average cost of a tele-tomography, tele-ECG and tele-ultrasound was USD2.6, and USD8.6 for tele-EEG, respectively. The cost reduction through the telediagnosis was 26.4 times for tomography, 4.5 times for ECG, 8.0 times for EEG and 8.3 times for ultrasound. The cost utility analysis performed demonstrates an economic benefit of USD12.9 million to the citizens of the fifty-four communities included in this project.

Despite the potential benefit of the telediagnosis (2) to facilitate the universal coverage, and optimize the use of scarce human and health financial resources shown in this study, other important aspects such as acceptance of the technology, patient satisfaction and a widespread use-assessment should be analyzed (3) before a large diffusion.
