To explore the construction of an integrated monitoring platform for Healthy Life Expectancy (HLE) statistics and to conduct a preliminary evaluation of its application effectiveness.

Challenges were analyzed to define development goals. Multiple sources of health and medical big data were integrated, and advanced technologies such as blockchain and big data processing were applied to enable dynamic monitoring, automated calculation, and comprehensive analysis of HLE and its determinants.

The platform successfully connected with information systems from tertiary hospitals nationwide, multiple public health data platforms, and various disease registries. Data completeness improved significantly from an average of 65% to over 92%. A monitoring system comprising five categories and more than 30 HLE-related indicators was established, identifying over 20 key factors strongly associated with HLE. The average approval time for data-sharing applications was reduced from seven working days to three, enhancing both security and efficiency in data sharing.

The integrated monitoring platform for HLE statistics demonstrates substantial value in improving the efficiency of health data analysis, supporting policy formulation, and guiding health interventions. It provides robust data support and technological assurance for the advancement of the Healthy China initiative.
