Customer Discovery as the First Essential Step for Successful Health Information Technology System Development / 대한의료정보학회지

OBJECTIVES: Customer discovery (CD) is a method to determine if there are actual customers for a product/service and what they would want before actually developing the product/service. This concept, however, is rather new to health information technology (IT) systems. Therefore, the aim of this paper was to demonstrate how to use the CD method in developing a comprehensive health IT service for patients with knee/leg pain. METHODS: We participated in a 6-week I-Corps program to perform CD, in which we interviewed 55 people in person, by phone, or by video conference within 6 weeks: 4 weeks in the United States and 2 weeks in Korea. The interviewees included orthopedic doctors, physical therapists, physical trainers, physicians, researchers, pharmacists, vendors, and patients. By analyzing the interview data, the aim was to revise our business model accordingly. RESULTS: Using the CD approach enabled us to understand the customer segments and identify value propositions. We concluded that a facilitating tele-rehabilitation system is needed the most and that the most suitable customer segment is early stage arthritis patients. We identified a new design concept for the customer segment. Furthermore, CD is required to identify value propositions in detail. CONCLUSIONS: CD is crucial to determine a more desirable direction in developing health IT systems, and it can be a powerful tool to increase the potential for successful commercialization in the health IT field.

Needs for Health Care Services for Active Aging of Home-Dwellers With Age

BACKGROUND: In a rapidly aging population, the importance of the quality of life of the elderly has been emphasized. The need for special care services according to an individual's physical, emotional, and social functions changes with aging. This study was conducted to analyze the needs of home dwellers in terms of health-care services for active aging. METHODS: The study subjects were 869 adults older than 40 years who lived in houses. They responded to a survey that inquired about the importance of each health-care item for active aging at home. The important items for active aging at home were graded by using a 5-point Likert scale. RESULTS: Among the items, "affection" topped the list, with 4.68 points, followed by cognitive function (4.67 points) and "social relations" (4.59 points). The top 3 items had no significant differences between the age groups. However, some items related to activities of daily living (ADL; including bathing, eating, and ambulating.) and instrumental ADL (IADL; including taking medicines and preparing meals) had significant differences between the age groups. Compared with the subjects in the older age groups, the subjects in the forties age group placed less importance on ADL and IADL. CONCLUSION: For the subjects who lived in houses, affection, cognitive function, and social relation are highly important for as active aging, regardless of age. ADL and IADL are regarded as more important in ≥50 years age groups.
