As medical service paradigm has shifted from disease treatment to disease prevention, interest in information and communication technology (ICT)-based healthcare, through which medical service can be received without time and space restrictions, has increased. ICT-based healthcare is characterized by the following: first, wired/wireless network ICT is used, and second, medical service to determine one’s health state or to provide treatment can be offered anywhere and anytime. Such a medical service is called telemedicine or u-Health (all these are ICT-based healthcare services) [1].

As a recent technological change in medical service, the evolution of IoT-Cloud Big data-Mobile (ICDBM) has enabled real time and intelligent customized services and leads the innovation in the medical service field. Various research on linking different types of technologies, such as artificial intelligence, wearables, and robots, as well as ICDBM, have been carried out recently [2].

Business Insider (BI) Intelligence projects that the size of the global wearable device market will reach US$ 14 billion in 2018 [3], while Gartner predicted that the global IoT market will reach US$ 309.0 billion in 2020 and that healthcare will take up the highest ratio at 15% of the IoT market [4]. Cisco Systems, Inc. forecasted that a value creation of US$ 1 trillion, particularly US$ 106.0 billion in value creation in the patient care sector, will be made with the healthcare industry’s IoT application in 2020 [5]. McKinsey estimated US$ 1.6 trillion in value creation in 2025 [6]. The competition to secure healthcare platforms among ICT companies or in the ICT industry has become fierce at home and abroad, and many companies have released relevant products and medical services, with Nike+ Fuelband and Fitbit being representative cases. Cases related to medical diagnosis-assisting service are NuVant and Triggerfish [7]. In Korea, the demand for IT utilizing services increased according to the increase in the introduction of the Internet, mobile gadgets, and smart devices [8]. In spite of a pre-announcement of legislation on telemedicine, centered on local hospitals in October 2013 and June 2016, the identification of the medical service area addressing the need of medical service providers and targets, along with the identification of its marketability status, has not been sufficiently conducted [910].

ICT-based healthcare service is projected to generate positive results in the healthcare market through treatment result improvement, medical service expenditure reduction, and patients’ active participation [11]. Nonetheless, ICT-based healthcare is closely related to life in a broad sense, and there is an opinion that the acceptance of relatively innovative ICT-based healthcare can be negative or delayed [12]. Awareness of telemedicine is low, and so is the intention to use it [13]; therefore, there is a need to determine how the medical staff, who are the providers of medical service, and the consumers, who are the service targets, perceive ICT-based healthcare service in order to adopt and activate telemedicine.

Concerning existing domestic and international studies on ICT-based healthcare service, various studies including doctors’ positive or negative effects, usage effects and usage satisfaction have been conducted [141516]. However, studies on consumers’ acceptability of ICT-based healthcare service are insufficient. In this study, the factors affecting service targets’ awareness, use, or acceptability of ICT-based healthcare were examined. This study presents measures to induce the adoption and activation of service targets’ active ICT-based healthcare service.

This study surveyed the awareness of service targets on ICT-based healthcare service for prevention-centered medical service, which as attracting attention in the healthcare market. Furthermore, the factors affecting acceptability and that can generate positive effects to service targets for the activation of telemedicine were analyzed. Based on the results, this study presents directions for ICT-based healthcare service activation.

First, ICT-based healthcare service is a solution for chronic patients and the aging society. If telemedicine is actively carried out between patients and doctors through ICT, personally customized service and prevention service can be offered through temporal and spatial expansions of medical service, which will be greatly advantageous to all concerned [1117]. Upon looking at the survey result of service targets’ awareness of ICT-based healthcare, first, the demand on physiological signal measurement including 279 people (94.3%) for blood pressure, 277 people (93.6%) for glucose, and 273 people (92.2%) for obesity was high in the desired coverage areas. As for the group requiring the use of service, the need appears higher among chronic patients and aged people or among 289 people (97.6%) with diabetes, heart disease and hypertension.

Second, based on the survey, family history of disease and health concerns were found to be factors affecting acceptability. Therefore, there is a need to focus on the ICT-based healthcare service targeting those factors [18]. As a result of surveying service targets’ personal characteristics according to acceptability, the significance probability of family history of disease and health concerns were 0.016 and 0.002, respectively; thus, the result was significant. Those who had a high degree of health concerns and a family history of chronic diseases felt more of a need for the service. In a previous study, those who were interested in healthcare showed participation intention to overcome difficulties in the process of using ICT-based healthcare service face-to-face, and an in-depth survey targeting those who were offered the ICT-based healthcare service within a national project [19]. For patients with chronic diseases or the elderly, continuous self-management is needed [20]. In fact, if self-management service based on the medical service provider’s professional guide and care is carried out, the optimal effect can be generated [2122].

Third, a policy to concentrate on ICT-based healthcare for those in their 40s is necessary. As a result of looking at acceptability difference by age groups, the differences were not statistically significant, but people in their 40s had a higher acceptability than those in their 20s and 50 or over. This means that those in their 40s are in the period in which health concerns become high, and they can use services like ICT-based technology relatively without burden, compared to other age groups. Furthermore, the 40s age group seems to be the age group that has the intention to participate in the ICT-based healthcare [2324]. According to the 2014 data of Statistics Korea, the prevalence rates become high starting from those in their 40s, given that high blood pressure patients rose from 7.3% in their 30s to 17.7% in their 40s, whereas cholesterolemia rose from 6% among those in their 30s to 12.6% among those in their 40s [25]. Concerning the death rate due to neoplasm (cancer), it became higher from 10.2% among those between 30 and 34 to 19.9% among those between 35 and 40, to 35.4% among those between 40 and 44, and 63.7% among those between 45 and 49. This data suggests that concentrated care for healthcare and prevention should start in full-swing among those in their 40s, when aging starts in earnest. Therefore, it is desirable to focus on people in their 40s, while ICT-based healthcare service encompasses chronic disease patients and elderly people.

The conclusion of this study is as follows: As a result of the service target’s views on ICT-based healthcare, continuous care was surveyed to be necessary for chronic diseases such as diabetes, heart disease, and hypertension and for the age group of 50 or over. The mean acceptability of the service target with high health concerns and family history of disease was high in this study. Acceptability became higher, as self-management necessity and usage satisfaction were higher.

The study had a weakness in that the consensus on telemedicine was not ensured, and threats on institutional problems such as personal information protection and relevant regulations exist in the ICT-based healthcare service. However, the strength is that patients can actively participate and have opportunities for treatment result improvement and medical service expense reduction, which is projected to bring about positive results to the healthcare market. Through this study, a positive awareness of service targets on ICT-based healthcare service was identified. The fact that acceptability is higher for persons with a family history of disease and higher health concerns may lead to service targets’ active participation. This study drew a result that a policy for the prevention and motivation for active participation for those in their 40s (who had high prevalence rates) was needed. If an analysis is conducted by expanding the ICT-based healthcare service target to those having actual experience of the service and by extensively segmenting the acceptability and effects, the study is expected to more clearly contribute to ICT-based healthcare service design.
