Background
Populations are ageing at an increasing rate in many nations around the world, as fertility rates decline and life expectancy rises [
1]. China’s population of adults aged 65 and older in China had reached 190 million by the end of 2020, accounting for 13.5% of the total population [
2]. More recently, due to the COVID-19 pandemic, prevention and control measures such as isolation, are forcing senior care services to seek new solutions by information technology and smart products. Therefore, there is an urgent need to transform and upgrade the traditional family care services. Smart home care, also known as the “intelligent senior care system” and “fully intelligent senior care system” [
3], refers to the Internet of Things (IoT), computing techniques, artificial intelligence (AI), automation and intelligent systems, which are increasingly used to monitor daily conditions and support senior care activities at home [
4]. These technologies are available for sensing, predicting, reminding and responding to the elderly community’s daily requirements, assisting them in a timely and socially correct way [
5]. Thus, smart home care can augment existing aging resources and support the older adults to age in place to achieve ageing actively for China and even the world.
It is imperative to develop a scientific index system for evaluating the quality of smart home care, providing a reference for the government bodies, senior care enterprises and communities to take measures to enhance the quality and effectiveness of smart home care. The Chinese government developed a “Medium and Long-term Plan for actively coping with population ageing” in 2019, proposing to strengthen technological innovation capacity in response to population ageing [
6]. However, smart senior care also face some challenges, such as low utilization rate caused by the digital divide, structural mismatch [
7], low quality [
8] and even the dilemma of having a platform but without services [
9] despite of achieving initial results in recent years. To address such challenges, it is of essential importance to systematically evaluate the smart senior care.
Generally,there is a lack of panoramic and comparative analyses of smart senior care. Various studies have been conducted on the feasibility and effectiveness of smart homes or a specific technology in foreign countries. Previous studies have shown that smart home or assistive technology plays an important role in promoting the physical and mental health of the elderly individuals. They assist the elderly to live independently and support social participation, improve the quality of life of the elderly [
10], and alleviate the burden on family caregivers and society [
11]. For example, Cavallo, F [
12] pointed out that robotic services permit older people to remain in their homes and facilitate their independent living. Additionally, Andres [
13] through bibliometric network analysis, found that various technologies are beneficial for health regulation, emotion recognition, mobility, localization and fall detection. Similarly, many studies in China have shown smart products and technologies to some extent enhance the satisfaction of elderly services and improves the quality of smart elderly services [
13,
14]. He Ni [
15] also pointed out that the application of artificial intelligence products makes a significant contribution to the quality of senior care services in general, but varies from different products. However, only very few studies have focused on developing a quality index system of smart care in China. For instance, Geng Z et al. [
16] constructed a three-level evaluation index system of smart senior care by applying the Delphi and AHP methods. Therefore, how to systematically and scientifically evaluate the quality of community-based smart home care services remain needs to be further explored.
An effective evaluation index system should reflect the elements of smart care, and should be in keeping with the prevailing situation of smart care in the community. Among many service quality assessment methods, the SERVQUAL model is the most widely used and authoritative service quality assessment tool, and the model is well-respected [
17]. However, some researchers have questioned the industrial applicability of the model [
17,
18]. Likewise, as some scholars have pointed out, the framework must be adapted and supplemented when necessary to suit the specific needs of certain organizations [
19,
20]. As the model continues to develop and mature, the industry’s unique characteristics are gradually incorporated into the model in China, and the SERVQUAL model is thus constantly revised.
The present paper attempts to fills the gaps identified in the above literature. Different from the form of care services for seniors in institutions or nursing homes, this paper focuses on the establishment of an index system for evaluating the quality of smart home care services for older adults in the community. To construct such an index system, using the cases of Guangzhou and Shenzhen, we undertook a literature review, conducted semi-structured field interviews and utilized the Delphi method and the analytical hierarchy process (AHP) method.
Discussion
Smart care is proposed based on screening and addressing the needs of elderly individuals, identifying and resolving the risks of the elderly and achieving the realistic goal of meeting their personalized and multilevel service needs and demands [
7]. Coinciding with the intersection of the silver-hair wave and the digital wave, intelligent care is currently one of the most critical tasks in most countries and areas. With the purpose of realizing sustainable development of smart care, the key point is to conduct scientific evaluation norms and guidelines. However, smart care services in China are still in the initial stage, and further research into how to systematically and scientifically evaluate the quality of smart home care services for community-dwelling older individuals is much needed. In this work, to ensure that older adults ageing in place receive high-quality senior care services and to promote the full flowering of smart senior care, we have drawn on the SERVQUAL model and combined qualitative and quantitative analyses using the Delphi and AHP methods to construct the index system for smart senior care and obtain the weights.
The characteristics of quality index system for smart home care
In sum, the quality evaluation index system for smart home care services for older adults in the community identified in this study has the following characteristics. First, the index system better reflects the connotation of smart care for the elderly, and highlights the characteristics and advantages of “wisdom” in the process of aging service provision. Secondly, the evaluation indices are more optimized and have stronger realism. In the process of index development, we also took into account the “fear of technology” among the elderly and their concern about the leakage of personal privacy in the process of smart senior care development in the era of big data. Rooted in China’s national conditions, the final secondary indicators are directly measurable indicators based on the actual situation in Guangzhou and Shenzhen, which can be used to intuitively measure the evaluation of elderly users on the quality of smart senior care services.
Result of index weight analysis
From the criteria level, the weighted value of the five established first-level indices is shown in Table
6: smart emergency assistance (0.332), smart meal assistance (0.272) and smart care assistance (0.229). This, indicates that these three indices are the key parts used to measure the quality of community smart home care, whereas the weight values of smart cleaning assistance and smart amusement assistance are relatively lower, namely, 0.110 and 0.057 respectively. The results from the current study suggest that when constructing the smart senior care service system, the development, design, popularization and service quality improvement of equipment related to emergency assistance, meal assistance and medical care assistance must be prioritized. Actually, through wearable devices and intelligent monitoring service devices, intelligent emergency assistance and intelligent medical assistance can realize the functions of positioning, monitoring and assisting elderly individuals. This can help the elderly achieve independence and effectively improve the quality of intelligent elderly care and help the development of smart elderly care. Smart assistance for emergency and smart assistance for medical care was affirmed by foreign researchers earlier. They have also advocated the expansion of the coverage of information technology in home care services [
32] and fully exploit smart devices and technologies such as remote intelligent control to respond quickly to remote calls for assistance from elderly individuals. This will lower the cost of medical care integration, and alleviate the shortage of care services [
33]. Similarly, a study has also proposed that at present, the fields with a high embedding degree of Internet technology largely focus on delivering meals, life care and medical services. However, due to the inherent deficiency of Internet technology in providing spiritual comfort [
34], the embedding degree of Internet technology is limited, and it is difficult to fully rely on relevant devices or terminals. They can only play a supplementary role [
35]. It is noteworthy that, as the development of smart elderly related industries is still in the preliminary stage, the content of smart elderly services still has limitations and lacks uniformity. In the future, with the continued growth of smart senior care, the weight of smart amusement assistance has more room to rise, which is also in harmony with the idea of some foreign scholars. For instance, Godfrey [
36] suggested that science and technology should be integrated into the traditional elderly care model to innovate the social interaction of the elderly through information technology. Similarly, Khaksar [
10] argued that nursing homes should use social robots to help older adults overcome social barriers and innovate smart senior care services from theory to practice.
From the program level, the indicators with higher weight values are mostly focused on the three dimensions of timeliness, reliability and ease of use. In other words, efforts must be made in the following areas during the construction of smart home care services for older adults in the community: guarantee timely response to user needs and timely provision of services; secure satisfactory services provided by professionals [
37], enhance the ability of the platform to make adjustments based on user feedback and to stress confidentiality of user information [
24,
38,
39]; ensure that the design of smart devices and systems is age-friendly and eliminate the digital divide as much as possible [
37]. Additionally, the finding from the weight values of the secondary index, it shows that the weights of the indicators under the “empathy” dimension is generally the lowest. The major reason for this is that the Internet has not yet been deeply integrated into the senior care industry in China. This, makes it difficult to provide personalized and customized services of different types and pricing in accordance with the situation, needs and preferences of elderly users.
The combination weights are able to reflect the importance of the secondary indicators for all service components. In the combination weights, there are 15 indicators that exceed the average weights. The high indicator weights are largely distributed under the three dimensions of timeliness, reliability and ease of use of each service content. This is basically consistent with the results of the weights of the primary and secondary indicators, also implying that these three dimensions have a significant status and role in the evaluation of smart home care services for older adults in the community. Yang Bo in China [
21] first tried to construct a scale for the quality of smart home care services, and concluded that the five service quality dimensions in descending order of weight were: reliability>empathy>timeliness>ease of use>tangibility. Our study concludes that timeliness, reliability, and ease of use are more important, which is consistent with previous findings to some extent [
21]. However, studies have produced a conflicting result in regard to the importance of “empathy” [
21]. The inconsistent findings could be caused by the heterogeneity of perspectives and cultural backgrounds of those interviewed and the consultation participants. Therefore, further studies are needed to confirm the importance of the different dimensions.
Strength and limitation
This study has established a system for evaluating the service quality of intelligent home care services for seniors in the community. To begin with, this index system can be used to evaluate the current situation of smart home senior care service quality, summarize the existing problems, explore the key factors and effective paths to achieve high quality. This index system, furthermore, may also be used as a regulatory benchmark to guide the government, senior care enterprises and communities to take measures to advance the quality. However, there are still some shortcomings in the study. First, the reliability, differentiation and representativeness of the indicators in the index system need to be further tested by specific applications. Accordingly, in the future, we will use this index system to conduct field research among elderly users, so that the evaluation index system can be continuously improved. Furthermore, since the constructed evaluation index system is based on the specific practices in Guangdong Province, the external probability validity of the service evaluation index system constructed in this study may have certain limitations. Thus, further in-depth research is needed to expand its empirical scope. Next, we will use this index system to conduct field research among the users of smart home care services, so that the evaluation index system can be continuously improved.
Conclusion
Smart home care for the elderly in the community is the future of the silver ageing industry. It is imperative to evaluate the service quality based on the actual practice status, and emphasize the “ people-centeredness “ nature of the service, to achieve the goal of high-quality development. In summary, this study has contributed to the development of indicators for evaluating the quality of smart home care for China’s community-dwelling older adults. In compliance with the applicable conditions in the pilot cities in Guangdong Province, a quantitative quality evaluation index system was constructed. In the present study, the outcomes revealed that more resources should be invested into smart emergency assistance, smart meal assistance and smart medical assistance, which have higher weights among the five smart elderly service items. In addition, the weight distribution of the secondary evaluation index have demonstrated it is of essential importance to prioritize the timeliness, reliability, and ease of use of smart senior care services, thereby facilitating the quality of smart senior care services. These findings lay a good foundation for further research on the quality evaluation of smart care for community-dwelling elderly individuals. Finally, in the era of intelligence, the role of information technology and intelligent products in meeting the spiritual needs of the elderly is still severely limited. Hence, more humanistic care should be given to the older adults to raise the temperature of elderly services.
