In 2020, when the Covid-19 pandemic began, Professor Alejandro Posadas National Hospital implemented clinical monitoring of patients and their contacts by telephone to manage the overwhelming demand for assistance and avoid overcrowding. This led to the formation of a Telephone Monitoring team. The team’s success prompted the hospital to explore other areas where the tool could be applied. In 2021, the hospital continued to use the Telephone Monitoring team, adapting it to new lines of work where patient care traceability was critical for ensuring access to the healthcare system. This article examines the role of patient navigation in improving healthcare outcomes, including better access and quality of care for underserved populations. The hospital institutionalized the Telephone Monitoring device in February 2023 as a sector of Assistance Relinking, adding another weapon to benefit patients by increasing their safety and improving the quality of care.
