Mexico's Institute for Social Security and Services for State Workers (Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado, ISSSTE) developed and deployed ASISSSTE, an omnichannel digital platform that integrates a mobile application, chatbot, web portal, and telephone line to deliver 21 institutional services to its approximately 13.6 million beneficiaries (derechohabientes) and pensioners. The platform was launched on 11 April 2022 as part of a broader digital transformation strategy to consolidate access to previously dispersed government social insurance services into a single, unified digital interface.
The ASISSSTE ecosystem comprises four primary channels. The web portal (asissste.issste.gob.mx) provides digital access to appointment scheduling, service consultation, and online transactions. The ASISSSTE telephone line (55 4000 1000, option one) enables voice-based access to medical appointments, guidance, loan information, and FOVISSSTE housing assistance. The ASISSSTE Movil mobile application — available on both iOS and Android — offers appointment scheduling, digital credentials with QR codes, rights verification documents, unified electronic health records, complaint management, and digital identification. The Virtual ASISSSTE chatbot uses natural language processing to facilitate medical appointment scheduling, providing a tool available 24 hours a day through which users can consult availability, select dates, confirm, or cancel appointments using natural and simple language without needing to travel to a clinic or call by phone.
ASSISSTTE's primary operational achievement has been the digitisation of medical appointment management across ISSSTE's network of over 600 first-level medical units nationwide, achieving 100 percent coverage at the primary care level. The platform manages approximately 41,000 medical appointments daily on average, with more than 2 million total appointments programmed through the system. Appointment booking allows scheduling up to 15 days in advance. Services span family medicine, dentistry, geriatrics, psychology, and reproductive health consultations, as well as administrative procedures including personal credit (loan) processing, certificate issuance, electronic file access, pension simulators, and citizen feedback portals.
The WhatsApp chatbot component was developed to address the digital preferences of ISSSTE's beneficiary population, particularly older adults who have demonstrated greater familiarity and affinity with WhatsApp compared to dedicated mobile applications. The chatbot automates the appointment scheduling process, enabling beneficiaries to interact in natural language to check availability, select preferred dates and times, and confirm or cancel appointments without requiring in-person visits to clinics or telephone calls. As of early 2025, the WhatsApp chatbot was in internal testing, with a first production version projected for mid-2025. A voicebot for voice-based scheduling and consultations was also under development.
Beyond appointment management, ASISSSTE integrates with several clinical and administrative systems including AAMATES (a clinical process standardisation platform), unified electronic health records, electronic prescriptions, a home oxygen management system, a medical imaging repository, peritoneal dialysis management, medical references and counter-references, medical licence processing, and haemodynamics services. The platform implements interoperability with the unified electronic health record, digital security through electronic signatures and QR codes, and centralised national registries for coordinated care across multiple levels of the health system. An analytics layer called ASISSSTE 360 was under development to provide data-driven insights across the platform.
The ASISSSTE mobile application had over 180,000 active users and was available through 35 administrative representation offices. The platform also extended to administrative services including personal credit applications, with a fully digital personal credit process using electronic signatures under development. The digital credential feature generates a QR-coded identification card accessible through the mobile app.
The International Social Security Association (ISSA) recognised ASISSSTE as a Good Practice (gp/279138), describing it as an institutional digital ecosystem that leverages technological tools to improve service delivery and communication with beneficiaries. The ISSA recognition highlights ASISSSTE's role in integrating previously independent systems to improve internal processes and facilitate efficient, citizen-centric access to ISSSTE's full range of social insurance services.
The platform was developed under the leadership of Alejandra Fernández Vélez, IT Subdirector of ISSSTE, who described the vision as implementing the latest technology to become 'the great concentrator of digital access' to institutional services, with the goal of making 'everything mobile.' The ability for beneficiaries to arrive at medical units with a pre-scheduled appointment was cited as representing significant progress in service delivery.
From a social protection perspective, ASISSSTE serves as the digital front door to Mexico's second-largest social insurance institution. ISSSTE provides comprehensive social insurance coverage to state employees and their families, including health services, pensions, housing support (through FOVISSSTE), personal loans, and various social benefits. The platform's omnichannel approach — combining app, chatbot, web, and phone — aims to reduce barriers to service access, particularly for pensioners and older adults who may face mobility or digital literacy challenges. The chatbot's natural language interface and WhatsApp integration specifically target accessibility for populations who might otherwise struggle with app-based or web-based interfaces.
