The health management system "HM-neo" is a system developed by NTT TechnoCross that provides menus aligned with the workflow of the health management department, including planning health check-ups, managing progress, assessments and results, and recording interviews. In addition to health check-up results, medical questionnaires, stress checks, overtime hours, and disease information, it also supports the management of work history for employees engaged in hazardous work, centralizing all health data, including special health check-ups. It reduces the workload of the HR department's reporting tasks, allowing health management staff to focus on health management operations. The health management system HM-neo comes standard with the health management (R) analysis support tool HM-viewer. The previously cumbersome aggregation and analysis can now be viewed on a dashboard. 【Features】 ■ The system completes health check-up operations from preparation, special work management, assessment support, to result management. ■ Centralized management of stress checks, overtime hours, and disease management. ■ Comprehensive features that robustly support industrial physician interviews and health guidance. * For more details, please refer to the PDF materials or feel free to contact us. * Health management (R) is a registered trademark of the NPO Health Management Research Association.
