Nowadays a few concepts of games and game design are used in different non-entertainment domains (this is also called gamification). Part of this gamification is also emerging in the health sector. This work-in-progress paper tries to define a methodology and an architecture how an achievement based service in healthcare can be designed, analyzed and implemented. This service uses patient data from different sources (e.g., from a patient´s personal health record) to share anonymized health related information/achievements with other people. Thus, it might build up a comparative behavior between patients and motivate them to increase the usage of a personal health record.
