RESUMEN
Introduction: The objectives of this article are to review previously established tele-intensive care unit (ICU) services describing their impact at the technical and medical level, and to propose an implementation plan to equip health care facilities in need of telehealth. Materials and Methods: We searched MEDLINE, EMBASE, PubMed, and ISI web of knowledge, using terms related to "e-ICU" and "tele-ICU" from inception to May 2021. Discussion: At the technical level, an increase in private insurance enrollment and routine checkups, as well as a reduction in hospital utilization rates and improvement in health outcomes was seen in the aftermath of the adoption of telehealth insurance mandates. Moreover, e-ICU helped reducing mortality and length of hospital stay of critically ill patients. The main approach to implementation should include features that are widely accepted for quality improvement, including being focused on patient-centered outcomes, having strong executive support, and targeting changes that were known to improve outcomes. HL7 Fast Healthcare Interoperability Resources stands out as one of the best candidates to achieve structural interoperability for patient health records. Conclusions: Adoption of tele-ICU services requires a substantial up-front investment and ongoing cost of maintenance. This could be challenging for hospitals with low budgets. Hence the importance of further investigating more efficient strategies of e-ICU services integration and implementation.
