Gamifying Patient's Personal Data Validation and Completion in a Personal Health Record

Electronic personal health record systems (PHRs) support patient centered healthcare by making medical records and other relevant information accessible to patients, thus assisting patients in health self-management[1,2]. The Hospital Italiano de Buenos Aires (HIBA) is a private hospital in Buenos Aires, capital of Argentina. It has 500 beds and serves around 50,000 patients per month. Its main facilities cover a surface area of 78,000 m² (850,000 ft²). The hospital treats both private patients and those derived by social security. It also provides its own Health Maintenance Organization (HMO) being the most important pre-paid healthcare service in Argentina, with about 150,000 clients. HIBA has a Health Information System (HIS) and Electronic Health Records (EHR) since 1998 and implemented a PHR in 2007. The PHR gives patients access to aspects of the EHR related to their Health Care (laboratory, diagnosis, preventive information, medications lists), supports messaging with their physician, scheduling services and medication delivery for Self management, among other things. The majority of HIBA HMO affiliates are enrolled to this PHR. In 2015 HIBA underwent the process of accreditation by the United States Joint Commission[3]. As part of this process, HIBA redefined and refined the EHR/PHR data set, including new fields and regrouping pre-existent ones. EHR/PHR's personal data set is now composed of a series of fields grouped as depicted below. Personal data information is a difficult data set to capture, particularly those regarding social and cultural background information[4]. This data set is not only useful to help better healthcare system management, it is also relevant as it is used for epidemiological and preventive purposes[5-7].

Gamification is a term used to describe using game elements in non-game environments to enhance user experience[8,9]. It has been incorporated with commercial success into several platforms (Linkedin, Badgeville, Facebook). While over the past years gamification elements have been incorporated in healthcare scenarios there is still little evidence on how effective they are[10-12]. Game elements provide engagement consistent with various theories of motivation[13], positive psychology (e.g., flow)[14], and also provide instant feedback. Feedback is more effective when it provides sufficient and specific information for goal achievement and is presented relatively close in time to the event being evaluated. Feedback can reference individual progress, can make social comparisons, or can refer to task criteria.

In order to assess whether gamification is an effective tactic to drive PHR users' behavior, an intervention was designed. The investigators used gamification elements such as points, graphical representations and playful attitude to the design and interactions of the Bio page in the Hospital's PHR. These elements provide instant feedback to user actions. A control group with no game elements will be compared with a gamified group to see if these new game elements would increase patient's personal data rectification, validation and completion in the Hospital's PHR. A status variable was created and assigned to all fields according to the following scheme:

• Completed: user has modified empty field.
• Corrected: user has modified non-empty field.
• Verified: user has updated Group but field data has experienced no change.
• Validated: user has clicked on the "validate" button.
