[PRIISMA Project: Transformation into a more preventive, resilient, comprehensive, innovative, sustainable, modern and accessible IMSS].

Two years after the onset of the COVID-19 pandemic, the Mexican Institute for Social Security (IMSS, according to its initials in Spanish) rethought new projects focused on the new needs of the population and social security organizations and institutions. The Institute, as a cornerstone in the search for the wellbeing of Mexicans, aligned with the National Development Plan and the Strategic Health for Wellbeing Program, sought to direct its transformation towards a preventive, resilient, comprehensive, innovative, sustainable, modern and accessible IMSS. For this reason, the Medical Services Director designed the PRIISMA Project, as the one that over the next three years could make possible to innovate and improve its medical care processes, starting with the recovery of medical services and identifying those groups of beneficiaries who experience the most vulnerable circumstances. The PRIISMA project consisted of five sub-projects: 1. Vulnerable groups; 2. Efficient and effective care; 3. Prevent IMSS plus; 4 IMSS University and 5. Recovery of medical services. The strategies of each project seek to improve medical care for all IMSS beneficiaries and users with a human rights perspective and by priority groups; the goal is reducing the gaps in access to health care, leaving no one behind and leaving no one out; and to surpass the goals for medical services provided before the pandemic. This document provides an overview of strategies and progress of the PRIISMA sub-projects achieved during 2022.
