ES·pera transforms fragmented official data regarding Spain's public healthcare waiting lists into clear, comparable visualizations that are linked to their sources. This tool aids citizens, journalists, and researchers in understanding access delays across various regions, hospitals, and specialties. It maintains a national dashboard that includes all official waiting list data from Spain and its autonomous communities, regularly updating the datasets in line with new releases from official sources. Each visualization retains the relevant source, period, and methodological information. Additionally, ES·pera plans to expand its coverage at the hospital and specialty levels through 2026, targeting the general population in the health sector.
