Abstract

:
Hospital environments are facing new challenges this century. One of the most important is the quality of services to patients. Social robots are gaining prominence due to the advantages they offer; in particular, several of their main uses have proven beneficial during the pandemic. This study aims to shed light on the current status of the design of social robots and their interaction with patients. To this end, a systematic review was conducted using WoS and MEDLINE, and the results were exhaustive analyzed. The authors found that most of the initiatives and projects serve the elderly and children, and specifically, that they helped these groups fight diseases such as dementia, autism spectrum disorder (ASD), cancer, and diabetes.

1. Introduction

In recent times, the academic community has taken a growing interest in human–robot interaction (HRI), particularly with social robots [1]. This field is dedicated to identifying, creating, and assessing robots and their interactions with people [2]. HRI includes computer science, engineering, psychology, and other areas of study involving these systems and social behaviors [1].
Social robots can help with long-term healthcare services, such as rehabilitation [3] or school attendance [4]; however, access to this technology requires a regulatory and ethical framework in the area of robotics research [3]. Assistive Ambient Living (AAL) supports healthcare services at home with e-tools and projects like ULISSE or ENRICHME, although the use of an interactive robot raises privacy and ethical concerns [5].
During the COVID-19 pandemic, society saw social robots being implemented in real settings and different applications [6]. The lockdown and the various measures adopted in countries, such as physical distancing and isolation, provided an opportunity to apply social robots as assistive tools during the pandemic, specifically in healthcare services [7].
As a result, social robots were crucial in reducing the spread of COVID-19 by performing certain functions like monitoring and supporting patients and healthcare professionals [8]. Furthermore, research has provided evidence that isolation and lockdowns have negatively impacted mental health and wellbeing [9], meaning social robots might be effective in helping and promoting wellbeing during a pandemic [10].
However, there are many unanswered questions involving the design of social robots as concerns their safety and the ethical principles involved in using them in healthcare settings. The research into their main uses and applications in hospitals is also lacking. For these reasons, in this paper, we will try to answer the following questions:
RQ1: How are social robots designed? Are they ethically designed?
RQ2: What are the main uses and applications of social robots in healthcare?
Our first research question involves three perspectives: design, interaction, and ethical issues. It is essential to determine what studies exist on the design of the software and hardware of social robots, so RQ1 seeks to shed light on this issue. Additionally, interaction is an essential ingredient in the development of social robots because they communicate and interact with human beings. RQ2 analyzes only that, while RQ1 addresses concerns involving social robots, with interaction and intelligence aspects being critical [11].
Thus, in this paper, we conduct a systematic review to answer these questions, focusing on the design of social robots and their applications in hospitals. We also provide the context and use of social robots in healthcare, answering the questions of what is being done and how they are being used. In addition, we analyze the ethical component in the design of social robots.
The paper is organized into several sections. Section 2 presents the methodology employed, and the results are presented in Section 3. Section 4 discusses the results in terms of the research questions. Finally, the conclusions are presented to provide a roadmap for designers of social robots for healthcare services.

2. Materials and Methods

2.1. Design

This article focuses on peer-reviewed journal articles and systematic reviews involving social robots and hospitals published between 1 January 1960 and 31 March 2021.

2.2. Databases and Search Strategy

The Web of Sciences WoS and MEDLINE were searched on 11 March 2021. This search was refined in terms of the document type (article or early access or meeting or clinical trial or case report or review), language (English), and research areas (computer science or robotics or automation control systems or engineering or health care sciences services or psychology or social sciences, other topics or geriatrics gerontology or behavioral sciences or medical informatics or oncology or communication or telecommunications or information science, library science or education, educational research or pediatrics or social issues or neurosciences, neurology, or experimental medicine or urology, nephrology). An advanced search was conducted using these terms: (Social Robot * AND hospital *). The flow diagram was created as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) [12] (see Figure 1).

2.3. Inclusion/Exclusion Criteria for Selecting the Studies

Two filters were used to identify eligible studies and ensure the reliability of the systematic review in the first screening. In the first filter, the three authors, using the consensus agreement [13], applied the first filter by screening eligible articles based on their titles and abstracts. With the resulting articles, each author independently applied the second filter and completed an inclusion/exclusion checklist while screening the titles, keywords, and abstracts resulting from the primary search. A qualitative analysis was conducted using consensus agreement to settle a disagreement in one session [13].
The articles reviewed were screened by title, keyword, and abstract and then classified into three categories: (a) articles or systematic reviews excluded for meeting exclusion criteria; (b) articles or systematic reviews excluded for meeting exclusion criteria but related to the subject; or (c) articles included because they satisfy all the inclusion criteria (Table 1). The full texts of the latter group were analyzed to answer two research questions.

3. Results

This search yielded 329 articles in two databases. After refinement involving document type, language, and research areas (Table 2), 112 articles passed the first screening. Based on the inclusion/exclusion criteria, we excluded 34 documents (23 empirical articles and 11 systematic reviews) with the second filter. Out of a total of 78 documents that were eligible to be read in full, 17 documents (16 empirical articles and 1 systematic review) were excluded after reading the full text for various reasons (13 studies could not be retrieved, 1 was written in a language other than English, 1 chapter, 1 collection of short, popular articles, 1 repeated). The total number of documents included in our review for analysis was 61 (57 empirical articles and 4 systematic reviews) (see Figure 1). Of all the papers analyzed, 22 were indexed in JCR (Q1 = 5; Q2 = 5; Q3 = 8; Q4 =4), one in SJR (Q3), and 32 were published in proceedings.
A bibliometric analysis performed using Bibliometrix (an R-tool) and VOSViewer [14] was carried out on the 112 eligible documents after the first screening, that considered the importance of: 1. The annual occurrences vs. years, 2. Evolution in time of titles and abstract terms, 3. Details of the child cluster, 4. Details of clusters for older people, 5. Healthcare connections, and 6. Factorial analysis corresponding to Multiple Correspondence Analysis (MCA), which yielded four stable factors.
An analysis of the 3198 terms (titles + abstracts) revealed the evolution in time using full counting, with the restriction of a minimum of 10 occurrences per term. Sixty-nine met the threshold. The 60% most relevant terms are shown in Figure 2, a total of 41 terms. For instance, social robotic, information and healthcare appear as terms used more since 2018, Figure 3. A detailed view of the Children cluster allows us to identify specific social robots (i.e., Pleo) and applications in some diseases (i.e., cancer and depression). The same process was used to find another user profile (older adult) (Figure 4). In Figure 5, a binary count was carried out with a total of 323 links and 3 main clusters, one of them being healthcare context. This figure shows the main connections (social robot with study, human robot interaction and assistive robot) as different ways to address healthcare environments from an engineering perspective. Figure 6 also reveals that design and interaction are key topics in defining the areas of expertise of social robots and that the selection of papers can help us answer our research questions.
Two tables are presented below. Table 3 includes the articles identified that address the first research question, while Table 4 contains the articles that address the second research question. Later in the paper, reference is made to how these articles, in some cases, can answer both questions.

4. Discussion

We have found in the literature numerous terms related to social robots such as (1) chatbot, (2) bot, (3) virtual assistant, (4) robot companion, (5) artificial social, intelligent machine, (6) social assistive robots, (7) telepresence robot, (8) remotely operated robot, (9) personal assistant, and (10) autonomous robot. In a way, all of them fall within our scope; the difference among them comes from the fact that some of them combine software and hardware (4–10), while others are usually only software (1–3). [43,60] offer exhaustive and historical reviews of robots. Specifically, in a healthcare context, we found that the most accurate definition is related to the central care concept. Thus, a social robot aims to serve a person in a caring interaction rather than perform a mechanical task [16], and it usually has hardware and software components.
As if this were not enough, there are also other associated terms that are commonly used that range from small, handheld devices like smartphones, to thermostats and pet-like robots, such as Paro or MiRo, all the way to life-sized humanoid robots, such as Nadine or Moxie. This suggests that this undertaking represents a highly variable space [15]. This article provides a technology classification: objects (i.e., a chair), tools (i.e., hammer), machines (i.e., coffee machines), artificially intelligent machines (i.e., smartphone), and artificially socially intelligent machines (i.e., Paro). Our target is the last of these, and sometimes semantics are involved, as we saw in the first paragraph. A series of dimensions is proposed in [15] to describe all of them in more detail: Prior experience/expectations, Automated functionality, Functional Repertoire, Form-function mapping, Size, Human-like form or motion, Socialness, and Intelligence.
When technology is a means to an end, some adaptations involving Lego are used [74] in the robotics program. Cloud computing technology is present too; Google and Microsoft have released chatbot health-platform services that are usable in everyday life [75].
The control of one’s actions and their consequences, or the sense of control, is called a sense of agency (SoA). Cozmo robots and Cozmo cubes reduce it, and in return, show that reduced SoA is not observed in the presence of a passive non-agent device [76].
In this work, we focused on the healthcare context. However, there are other reviews in other contexts, such as urban spaces and in artificially socially intelligent machines called social robots [47]. Next, we are going to discuss designing and interacting with social robots in healthcare contexts.
RQ1. How are social robots designed? Are they ethically designed?
The development of social robots includes several algorithms as well as different implementations, such as face recognition, speech recognition, cognitive and decision-making modules [29,39,40,42,44,60,61,66], emotional modules [47,50], and ergonomics [43], which must also be considered fundamental. Achieving new levels of conversational modeling and knowledge and providing intelligent interactive platforms that can interact with users is a promising field [75].
We found that 75% of HRI studies are laboratory-based [15], mainly intended to study certain aspects, such as prior experience/expectations, automated functionality, functional repertoire, form-function mapping, size, human-like form or motion, socialness, intelligence, and other bases for the development of robotic technology [34]. However, long-term interaction is a challenge for socially assistive and educational robots [23], and HRI research can be improved by studying the contexts [25].
Considerable research is being conducted in this regard to improve the navigation of social robots [27,28,30,48,61] in spaces where they must coexist with humans in accordance with subtle cultural rules [17] and taking into account certain disabilities, such as hearing impairment [77]. In [17], a model is proposed for the motion of a robot inside a hospital environment. Moreover, as a result of the COVID-19 pandemic, social interaction is restricted, and a minimum distance between robots and humans should be respected.
Regarding the appearance of robots or the features of robots intended for use by children or the elderly, pet-like SAR, like dinosaurs or animals (Pleo, Paro, Parrot, Aibo, Huggable, or iCat) are preferred [18,21,26,34,38]. People can also interpret affective non-verbal behavior in robots [21]. A stress-reducing effect on people who are ill in childhood and old age has been identified [24,62]. As concerns human-like robots, NAO is one of the most accepted robots in healthcare [65]. In [16] found the main concern with social robots to be their cultural acceptance and skills. Additionally, feminine robots are preferred by users. Another concern found in this study was to understand what the human is doing; however, the robot’s appearance depends on its application, the user’s age, and several other factors [33,60,61].
As a method for designing and implementing AAL facilities, the person-centered process has been found to be the best design methodology, as it allows for conversations between participants and healthcare professionals [78]. However, [19] found that highly developed algorithms were needed to integrate more general cognitive aspects in the robot to enable it to diagnose certain illnesses, such as ASD. Another methodology that is useful in healthcare contexts (children with diabetes) is Socio-Cognitive Engineering (SCE) [25], as it enables the integration of different theories, models, and visions of patients and caregivers. More ingredients can be added to the interaction, such as prediction and feedback. Such is the case when using NAO in heart disease settings, which offers users a new way to understand the meaning of their vital signs through human–robot interaction [79].
Although social robots can promote fundamental values of care (i.e., patient safety, dignity, and wellbeing [22,32]), some researchers believe that doing experiments to test social robots with child patients is not ethical [80]. Besides, care services are highly regulated, and special legislation is required for care-work robotics [22].
According to the International Federation of Robotics (IFR), there is a framework of components of ethical importance, the CCVSD (Care-Centered Value-Sensitive Design) approach [46]. It consists of a framework of components of ethical importance that provides a list of components to take into consideration when evaluating a care robot: the use context, the care practice, the actors involved, the type of care robot (its capabilities, appearance, etc.) and the list of values involved for the practice in question in the stated context (i.e., the interpretation and prioritization of care values) [46].
We found some ethical principles applied to the design of social robot applications in healthcare, such as autonomy, beneficence, non-maleficence, fidelity, justice, utility, and independence [78]. The same authors noted certain ethical requirements in artificial intelligence algorithms for AAL and social robots, like (1) human agency, (2) robustness, (3) privacy, (4) transparency, (5) non-discrimination, (6) wellbeing, and (7) accountability to account for the negative impacts of the systems. Some social robots must comply with the three fundamental guidelines of the Policy Department for Economic, Scientific, and Quality of Life Policies (IPOL) (i) Hospitality and inclusiveness, (ii) Comprehension of individual needs, and (iii) Non-intrusiveness [65]. The ethical dilemma must reconcile the technical problems with patients’ needs and rights, with health care services and hospital facilities, in keeping with the ethics in robotics used in medicine [11]. Ethical concerns in the design and use of social robots have been raised involving privacy, restraint, deception, accountability, and psychological damage [45].
Safety—both physical safety and psychological safety [16,17,43]—is another principle considered when designing social robots for healthcare. Security issues such as privacy violations and privacy protection for individuals have been considered in the design [47,65,81].
RQ2. What are the main uses and applications of social robots in healthcare?
Social robots can help with the global problem of the shortage of specialized medical personnel by doing several tasks [82], but their implementation in hospitals must be carried out conscientiously [23]. Robots have been used to quantify significant harm levels in autistic children, by professional caregivers of the elderly, to accompany the elderly while walking, to help persons with motor impairment (i.e., quadriplegia), to monitor and correct during rehabilitation for head, neck, and back pain [16,36], and as a mediator in the interaction with the physician or nurse who performed the treatment [18]. Additionally, social robots can be rehabilitation therapists at home [20] or do administrative tasks, such as reception [29,51] in hospitals [22,60]. They have also been used for edutainment purposes [30,70,80]. Moreover, robots can remind people to take medications, they offer entertainment and memory games, and can be used for videoconferencing [63]. They can be used remotely, connecting the hospital and a patient’s home [28,69,70]. Moreover, robots have been used to administer automatic questionnaires [52].
During the pandemic, social robots were employed for various purposes, such as the use of drones to enforce quarantine restrictions, alerting individuals to return to their homes, delivering medicine to patients with Covid-19 in Wuhan, and transferring test samples or helping with hospital admissions [6,8,10]. Additionally, mobile robots have been used for hospital logistics by sterilizing surfaces with UV light. Robots have been used to take temperature automatically using a thermal sensor. Social robots have reduced the loneliness of people and improved their mental health [8,83].
In healthcare specifically, care workers reject the use of social robots due to their perceptions of their applications, which poses a challenge to the effective implementation of social robots in hospitals [22].
There are two groups where applications that rely on social robots are more widespread within the healthcare environment, namely the elderly and children.
(a)
Elderly
The elderly can benefit from these assistive technologies. In [84], the researchers classify them as ICT (Information and Communication Technologies), Robotics, Telemedicine, Sensor Technology, Video games, and medication dispensing devices. They found that the studies targeted eight problems involving older adults: (1) dependent living (R), (2) fall risk, (3) chronic disease, (4) dementia, (5) social isolation (R), (6) depression (R), (7) poor wellbeing, and (8) poor medication management. (1), (5), and (6) were managed with help from social robots. Social robots have also been used for dementia rehabilitation in hospitals [37,41,44]. Robots have been used to improve quality of life and mood in the elderly, while reducing their loneliness [66].
Emotions are connected to social interactions [55]; this is the case for the elderly and (4) dementia patients [53,56]. It is a promising field for the PARO robot [68] and exhibits both benefits and barriers [71]. PARO can support the psychosocial needs of the elderly related to inclusion, identity, attachment, occupation, and comfort [68]. When it comes to expressing emotion and inducing empathy, ARI employs a few body cues simultaneously, mainly: facial displays, body movement, posture, and vocal cues [21]. AIBO, PARO, AIBO, and iCat are considered SAR (Social Assistive Robot and Companion). Six thousand, four hundred assisting robots were sold worldwide in health care contexts in 2017. The challenge is to clarify the role of robots in health care and regulate the services they provide through norms and codes of ethics [22].
Hospital personnel must take on arduous tasks that are often repetitive and burdensome, for which they do not have enough time. Here, social robots like Pepper also seem to have a chance to prove their usefulness with questionnaires [67].
Conditioning our home environments influences our wellbeing. They are a critical characteristic in the most vulnerable groups, as in the elderly, who routinely need health care assistance. For example, a virtual assistant and empathic coaches assisted older adults living independently at their homes [78].
For the elderly, robots are not just machines; they offer emotional support, much like a friend and companion who communicates and coexists [81].
(b)
Children
Children are the other vulnerable group where social robots are most applied, specifically with children suffering from diseases such as cancer [54,64]. Such is the case of ARASH [60]. Project MOnarCH (MOnarCH (Multi-Robot Cognitive Systems Operating in Hospitals) is a well-documented European FP7 project for edutainment activities in the pediatric ward of an oncological hospital [30,43,45,61]. Robots can improve the quality of life of children by interacting with them in hospitals through social and play dynamics, and as school teaching assistants [18,45,50].
In long periods of isolation, telepresence is a practical tool, as we saw in the first section [69], to treat pediatric cancers [31]. Additionally, for long-term relationships and bonding, PLEO is used in the caring system [62], where the child’s wellbeing is a priority. Because of its appearance, reminiscent of dinosaurs or an electronic toy, children found PLEO appealing [18]. Stress is a characteristic that is unfortunately also present during long periods of convalescence; interactive stuffed animals can positively influence a child’s mood and improve their quality of life during hospitalization. They also provide support when confronting a disease and can serve as a distraction during a medical procedure [24]. Moreover, pain and isolation, along with stress, can be addressed with a table-based avatar and its interactive social robot teddy bear [26]. Positive effects in children were noted using social robots, such as positive mood, engagement, trust, less stress or pain, more relaxation, smiling and openness, better communication, or emotional bonds with users [24,38,85].
The topic of automatic diagnoses can be found in the literature. It is applied in ASD (Autism Spectrum Disorder), where predicting the outcome of actions remains a challenge [16,27]. Understanding internal mental states is not the same as observing kinematics [19]. Observable actions include completing a puzzle or finding a given number of balls hidden around a room [27].
The “in the wild” concept is normally used to describe real conditions. Many activities are performed in laboratory conditions or controlled environments, which are not realistic at all. Some works, such as those involving children with diabetes, address it with a methodology for a human–robot partnership framework for prolonged care [25]. For example, the Pleo robot, a baby dinosaur robotic pet, works differently to assist children during hospitalization [38].
Other social robots were used for storing therapy treatments in the database, observing and evaluating therapy processes, or testing urine in children with cancer [54,64,86].
Future work needs to address the problems identified in the current research on the use of social robots by carrying out studies with larger sample sizes, with different populations in different contexts and situations, and with different physical and cognitive skills [66].

5. Conclusions

This paper analyzed the state-of-the-art concerning social robots in hospitals, focusing on healthcare contexts, and using WoS and PUBMED as the principal sources of data. As the principal outcomes of this systematic study, we note the following:
  • The interest in the use and real application of social robots in hospitals are relatively new: we observed that publications about this topic have increased from 2011. Although the review began in previous years, it was in 2011 when articles that met the inclusion criteria for this review began to appear with more frequency. Therefore, a growing interest in the use of assistive robots in the hospital setting can be observed from that year onwards.
  • There is still no academic consensus around the term “social robots”.
  • There are two central populations where social robots have been applied: children and the elderly.
  • Despite the principal potential users (children and elderly) of social robots, some applications for diseases appear in the literature: dementia, cancer, diabetes, and ASD.
  • The bibliometric study shows no consolidated research community around social robots in hospitals or for healthcare. Establishing a consolidated discipline around these topics would require an extensive collaboration network.
  • There are many benefits to using social robots in healthcare contexts, such as in mental health, where robots promote a positive mood, engagement, trust, less stress or pain, more relaxation, smiling and openness, better communication, and other emotional positive effects. Some patients felt deep emotions towards the social robots. Negative experiences appeared only in children on rare occasions.
  • Social robots are beneficial during long periods of isolation and were of help during the pandemic. Moreover, in different environments such as school or home, telepresence provided a good quality of service.
  • Although there are several ethical approaches to use robots in medicine, there is a challenge in accepting their use with children and as care workers. Differences were found depending on the context (workplace or home).
  • The main ethical concerns are privacy, restraint, deception, accountability, personal space, and psychological damage. Many researchers agree that more information and data must be gathered to improve their design and interaction to overcome ethical issues.
  • There are several initiatives involving ethics in technology that should be taken into account in the design of social robots for healthcare.
Regarding the design of the robot, the influence of the media factor, such as films or series, has been identified; the cultural imaginary creates expectations and prejudices towards social robots. This influence should not be taken into account in the initial phases of the design prototypes.
As we have seen, the uses of social robots are diverse, and focus on two groups (children and elderly), and very specific contexts usually associated with diseases or disabilities. However, due to the positive influence that in most cases they have on patients, and to the growing amount of literature on the subject, we predict that robot interactions will increase (i.e., expansion of emotional accompaniment, forms of communication, the performance of more types of routines), as will use contexts in hospitals (i.e., expanding contact with more types of patients and new ways of receiving patients).
Still, a question remains that should be explored: why have social robots not been widely used already in hospitals? Some reasons can be attributed to the maturity of the field of social robots, but not others. For instance, many reasons not related directly to engineering can act as barrier to the adoption of technology, including the use of robots in healthcare: for example, economic aspects, the medical staff’s lack of technical knowledge, or the staff’s behavioral intention [87,88]. Thus, the effective adoption of social robots in healthcare provides an interesting area of research to expand in the future.
