Objective: This study aims to explore the opinions on the insurance coverage of artificial intelligence (AI), as categorized based on the distinct value elements offered by AI, with a specific focus on patient-centered outcomes (PCOs). PCOs are distinguished from traditional clinical outcomes and focus on patient-reported experiences and values such as quality of life, functionality, well-being, physical or emotional status, and convenience. Materials and Methods: We classified the value elements provided by AI into four dimensions: clinical outcomes, economic aspects, organizational aspects, and non-clinical PCOs. The survey comprised three sections: 1) experiences with PCOs in evaluating AI, 2) opinions on the coverage of AI by the National Health Insurance of the Republic of Korea when AI demonstrated benefits across the four value elements, and 3) respondent characteristics. The opinions regarding AI insurance coverage were assessed dichotomously and semi-quantitatively: non-approval (0) vs. approval (on a 1-10 weight scale, with 10 indicating the strongest approval). The survey was conducted from July 4 to 26, 2023, using a web-based method. Responses to PCOs and other value elements were compared. Results: Among 200 respondents, 44 (22%) were patients/patient representatives, 64 (32%) were industry/developers, 60 (30%) were medical practitioners/doctors, and 32 (16%) were government health personnel. The level of experience with PCOs regarding AI was low, with only 7% (14/200) having direct experience and 10% (20/200) having any experience (either direct or indirect). The approval rate for insurance coverage for PCOs was 74% (148/200), significantly lower than the corresponding rates for other value elements (82.5%-93.5%; P ≤ 0.034). The approval strength was significantly lower for PCOs, with a mean weight ± standard deviation of 5.1 ± 3.5, compared to other value elements (P ≤ 0.036). Conclusion: There is currently limited demand for insurance coverage for AI that demonstrates benefits in terms of non-clinical PCOs.

Health technology assessment (HTA) is defined as multidisciplinary policy analysis to look into the medical, economic, social, and ethical implications of the development, distribution, and use of health technology. Following the recent changes in the social environment, there are increasing needs to improve Korea's healthcare environment by, inter alia, assessing health technologies in an organized, timely manner in accordance with the government's strategies to ensure that citizens' medical expenses are kept at a stable level. Dedicated to HTA and research, the National Evidence-based Healthcare Collaborating Agency (NECA) analyzes and provides grounds on the clinical safety, efficacy, and economic feasibility of health technologies. HTA offers the most suitable grounds for decision making not only by healthcare professionals but also by policy makers and citizens as seen in a case in 2009 where research revealed that glucosamine lacked preventive and treatment effects for osteoarthritis and glucosamine was subsequently excluded from the National Health Insurance's benefit list to stop the insurance scheme from suffering financial losses and citizens from paying unnecessary medical expenses. For the development of HTA in Korea, the NECA will continue exerting itself to accomplish its mission of providing policy support by health technology reassessment, promoting the establishment and use of big data and HTA platforms for public interest, and developing a new value-based HTA system.

The healthcare environment today is changing rapidly with factors of healthcare consumers in selecting medical institutions also altering at a fast pace under the circumstances. In this study, the theory of consumption values established by Sheth in 1991 is adopted in order to examine particular value affecting consumer selection of healthcare institutions. For the purpose of this study, healthcare consumers were surveyed using questionnaires developed based on the five values of Sheth supplemented by value of effort to acquire hospital information and value in health. Consequently, 24 consumption values affecting selection process were confirmed through discriminant analysis. As a result of regression analysis on factors affecting consumer selection of healthcare institution, effort to acquire hospital information and age among demographic characteristics of respondents are determined important predictors for consumer selection of general hospitals over clinics or small-sized hospitals. Further, service, reputation scale of healthcare institution among functional values and importance of health and effort to acquire hospital information among value in health are identified as significant predictors for consumer selection of large-sized general hospitals over clinic or small-sized hospitals. This study suggests not only vital implications for marketing strategy of healthcare institutions, but also methods to promote positive image for healthcare providers. In addition, this study closely examines the cause of the leaning phenomenon of healthcare comsumers toward large-sized general hospitals.

Automated medical claims processing and billing is a popular application domain of information technology. Managing medical related data is a tedious job for healthcare professionals, which distracts them from their main job of healthcare. The technology used in data management has a sound impact on the quality of healthcare data. Most of Information Technology (IT) organizations use conventional software development technology for the implementation of healthcare systems. The objective of this experimental study is to devise a mechanism for use of rule-based expert systems in medical related edits and compare it with the conventional software development technology. A sample of 100 medical edits is selected as a dataset to be tested for implementation using both technologies. Besides empirical analysis, paired t-test is also used to validate the statistical significance of the difference between the two techniques. The conventional software development technology took 254.5 working hours, while rule-based technology took 81 hours to process these edits. Rule-based technology outperformed the conventional systems by increasing the confidence value to 95% and reliability measure to 0.462 (which is < 0.5) which is three times more efficient than conventional software development technology.

Purpose The purpose of this study is to explain users' wearable healthcare device adoption using performance expectancy, effort expectancy, the hedonic motivation and price value of UTAUT2, and to identify the causal relationship between intention to use wearable healthcare device and innovation resistance formed by perceived risks. Design/methodology/approach The research model proposed in this study is based on UTAUT2(Extended Unified Theory of Acceptance and Use of Technology) and MIR(Model of Innovation Resistance). In specific, performance expectancy, effort expectancy, hedonic motivation and price value of UTAUT2 and innovation resistance formed by perceived risks of MIR are adopted in our research model. To validate the research model, we carry out the analysis of the survey data using Smart PLS 3.0 to test the hypotheses. Findings According to the empirical analysis results, this study confirms that the performance expectancy, effort expectancy, hedonic motivation, and price value have significant effects on the intention to use wearable healthcare devices. It also finds that perceived risk affects innovation resistance and in turn, innovation resistance affects the intention to use wearable healthcare devices.

A business model (BM) can be developed based on a business model framework (BMF) consisting of key components such as value proposition, customers, and resources. To systematically generate and analyze emerging BMs such as healthcare BM, an integration of diverse BMF components is needed. The present study is to establish a comprehensive BMF and evaluate its applicability to healthcare BMs. Based on a review of eight BMF studies, ten BMF components were identified and classified into five major components (value proposition, resources, organizing model, customers, and revenue model) and five minor components (technology, service platform, delivery, competitive strategy, and growth/exit) by analyses of frequency and functional importance. Lastly, the BMs of three emerging healthcare companies (WellDoc, Inc., CFW Shops, and Aravind Eye Care System) were analyzed and compared in terms of the proposed BMF components. The comprehensive BMF components presented in the study can be of help for developing new BMs and analyzing the strengths and weaknesses of BMs.

This paper assesses the evidence of the built environments' impact on patients' and staff's well-being. It also introduces evidence-based design (EBD) and discusses barriers and solutions for promoting EBD. EBD is an informed approach to design by improving design decisions based on best available knowledge. Designers should provide psychologically and physically supportive environments to promote occupants' well-being. There is increasing evidence that a poorly designed environment elicits negative feelings and stress. Better design will lead to better outcomes especially when it applied to a vulnerable population such as patients, children, and the elderly. Due to high demands of promoting patients' health, healthcare providers and professional designers have been searching for evidence to create healing environments. EBD has been well received in healthcare facilities design and is expanding to other types of environmental design such as educational and commercial design. Design firms should consider EBD as a value-added component of design to meet current and future challenges. It is important for designers to realize that engaging in EBD is not a rejection of creativity, but a means by which to scrutinize their design projects. With critical literature reviews on healing environments, there is sufficient evidence that well-designed environments can promote patients' and medical staff's health outcomes.

ICT는 제조기반 산업사회에서 가치사슬의 효율성/효과성의 지원을 목적으로 도입되었으나 정보기반 산업사회에서는 ICT가 시장 가치 창출의 주체가 되어 다중 가치사슬의 형성 가능성을 기대하게 하였다. 즉, ICT의 발전은 공급 및 수요의 다변화와 다양성의 동인이 되면서 가치를 창출하기 시작했고, 이를 중심으로 하는 신 가치 사슬의 등장은 구 가치사슬과의 충돌의 문제를 야기하였다. 즉, 다중 가치사슬이 존재 가능한 플랫폼에서는 가치사슬 간의 충돌, 중첩, 생성, 상실 등의 동적 상황 등에 따른 신/구 가치의 창출과 소멸 등이 발생하게 된다. 예를 들어, ICT에 기반을 둔 우버택시 서비스는 신 가치사슬을 형성하여 택시서비스 시장에서 신/구 가치사슬간의 충돌을 야기했다. 제조기반 산업사회에서는 단일 가치사슬의 시장 선점이 중요하였으나, ICT 기반 융합 제품/서비스/정보가 유통되는 플랫폼에서는 시장 상황 변수의 동적 변화에 따라 다중의 가치사슬이 존재하면서 서로 충돌과 공존을 야기하게 되었다. 따라서 ICT에 기반을 둔 지능형 정보사회의 발전과 함께 시장가치 최대화를 위해 다중 가치사슬 간 충돌 최소화와 공존의 최대 가능성을 높일 수 있는 모형의 제시가 중요하다. 본 연구에서는 먼저 의료서비스 시장을 중심으로 하는 다중 가치사슬의 동적 플랫폼 형성에 대해 논의한다. 즉, 의료서비스 시장에 ICT 기반 원격 및 지능형 의료서비스 등이 구 시장에 진입함으로써 발생하는 가치사슬 간의 충돌을 최소화하고 공존 가능성을 높이기 위한 공존 요인 변수에 대해 논의 한다. 이를 위해 다중의 공급과 소비 및 서비스가 존재 가능한 다중 가치사슬이 충돌 및 중첩하는 과정에서 공존 요인 변수 등에 기반하여 가치 사슬들을 동적으로 생성/변화/소멸 및 공존하기까지 의료서비스 플랫폼에 대해 논의한다. 또한 플랫폼 내의 각 가치사슬의 생산가치의 증가와 가치사슬 간의 상호 작용에 의한 부가가치의 창출 등에 의해 플랫폼의 총 가치가 증가 될 수 있음을 논의한다. 마지막으로 공존 모형을 제안하고 실험을 통해 가치사슬 간의 공존 가능성을 제시한다.
