Types, Roles, and Applications of Chatbots in Healthcare

Response generation chatbots, further classified as rule based, retrieval based, and generative, account for the process of analyzing inputs and generating responses [16]. Finally, human-aided classification incorporates human computation, which provides more flexibility and robustness but lacks the speed to accommodate more requests [17]. In the future, healthcare chatbots will get better at interacting with patients. The industry will flourish as more messaging bots become deeply integrated into healthcare systems. Many healthcare chatbots using artificial intelligence already exist in the healthcare industry.

Issues to consider are privacy or confidentiality, informed consent, and fairness. Although efforts have been made to address these concerns, current guidelines and policies are still far behind the rapid technological advances [94]. If you are interested in knowing how chatbots work, read our articles on voice recognition applications and natural language processing. The study focused on health-related apps that had an embedded text-based conversational agent and were available for free public download through the Google Play or Apple iOS store, and available in English. A healthbot was defined as a health-related conversational agent that facilitated a bidirectional (two-way) conversation.

Therefore, AI technologies (e.g. chatbots) should not be evaluated on the same level as human beings. AI technologies can perform some narrow tasks or functions better than humans, and their calculation power is faster and memory more reliable. However, occasionally, these technologies are presented, more or less implicitly, as replacements of the human actor on a task, suggesting that they—or their abilities/capabilities—are identifiable with human beings (or their abilities/capabilities). These healthcare-focused solutions allow developing robust chatbots faster and reduce compliance and integration risks.

Like falling dominoes, the large-scale deployment of chatbots can push HCPs and patients into novel forms of healthcare delivery, which can affect patients’ access to care and drive some to new provider options. Due to partly automated systems, patient frustration can reach boiling point when patients feel that they must first communicate with chatbots before they can schedule an appointment. The dominos fall when chatbots push patients from traditional clinical face-to-face practice to more complicated automated systems. The development—especially conceptual in nature—of ADM has one of its key moments in the aftermath of World War II, that is, the era of the Cold War. America and the Soviets were both keen (in their own ways) on find ways to automatise and streamline their societies (including decision-making). In the field of medical practice, probability assessments has been a recurring theme.

Cem’s work in Hypatos was covered by leading technology publications like TechCrunch and Business Insider. He graduated from Bogazici University as a computer engineer and holds an MBA from Columbia Business School. When you are ready to invest in conversational AI, you can identify the top vendors using our data-rich vendor list on voice AI or chatbot platforms. All authors contributed to the assessment of the apps, and to writing of the manuscript. For each app, data on the number of downloads were abstracted for five countries with the highest numbers of downloads over the previous 30 days. Chatbot apps were downloaded globally, including in several African and Asian countries with more limited smartphone penetration.

I will analyze their findings and present the pros and cons of incorporating artificial intelligence chatboxes into the healthcare industry. Such types of chatbots are specifically developed to provide mental health support. They apply methods from cognitive-behavioral therapy (CBT) and various other therapy approaches in their interactions with users. Through chatbots (and their technical functions), we can have only a very limited view of medical knowledge. The ‘rigid’ and formal systems of chatbots, even with the ML bend, are locked in certain a priori models of calculation. Expertise generally requires the intersubjective circulation of knowledge, that is, a pool of dynamic knowledge and intersubjective criticism of data, knowledge and processes (e.g. Prior 2003; Collins and Evans 2007).

They assist users in identifying symptoms and guide individuals to seek professional medical advice if needed. LeadSquared’s CRM is an entirely HIPAA-compliant software that will integrate with your healthcare chatbot smoothly. Chatbot becomes a vital point of communication and information gathering at unforeseeable times like a pandemic as it limits human interaction while still retaining patient engagement.

Hence, per the GDPR law, AI chatbots in the healthcare industry that use these LLMs are forbidden from being used in the EU. Healthcare providers can handle medical bills, insurance dealings, and claims automatically using AI-powered chatbots. Chatbots also support doctors in managing charges and the pre-authorization process.

The Ethics of Using Chatbots in Healthcare

Although this may seem as an attractive option for patients looking for a fast solution, computers are still prone to errors, and bypassing professional inspection may be an area of concern. Chatbots may also be an effective resource for patients who want to learn why a certain treatment is necessary. Madhu et al [31] proposed an interactive chatbot app that provides a list of available treatments for various diseases, including cancer. This system also informs the user of the composition and prescribed use of medications to help select the best course of action. The diagnosis and course of treatment for cancer are complex, so a more realistic system would be a chatbot used to connect users with appropriate specialists or resources. A text-to-text chatbot by Divya et al [32] engages patients regarding their medical symptoms to provide a personalized diagnosis and connects the user with the appropriate physician if major diseases are detected.

Hence, it’s very likely to persist and prosper in the future of the healthcare industry. The world witnessed its first psychotherapist chatbot in 1966 when Joseph Weizenbaum created ELIZA, a natural language processing program. It used pattern matching and substitution methodology to give responses, but limited communication abilities led to its downfall. Obviously, chatbots cannot replace therapists and physicians, but they can provide a trusted and unbiased go-to place for the patient around-the-clock.

For example, the startup Ada offers a medical chatbot focused specifically on health information lookup. It can address about 80% of common patient questions with 97% accuracy according to studies. The widespread use of chatbots can transform the relationship between healthcare professionals and customers, and may fail to take the process of diagnostic reasoning into account. You can foun additiona information about ai customer service and artificial intelligence and NLP. This process is inherently uncertain, and the diagnosis may evolve over time as new findings present themselves. GYANT, HealthTap, Babylon Health, and several other medical chatbots use a hybrid chatbot model that provides an interface for patients to speak with real doctors. The app users may engage in a live video or text consultation on the platform, bypassing hospital visits.

One stream of healthcare chatbot development focuses on deriving new knowledge from large datasets, such as scans. This is different from the more traditional image of chatbots that interact with people in real-time, using probabilistic scenarios to give recommendations that improve over time. The app helps people with addictions  by sending daily challenges designed around a particular stage of recovery and teaching them how to get rid of drugs and alcohol. The chatbot provides users with evidence-based tips, relying on a massive patient data set, plus, it works really well alongside other treatment models or can be used on its own. Hopefully, after reviewing these samples of the best healthcare chatbots above, you’ll be inspired by how your chatbot solution for the healthcare industry can enhance provider/patient experiences.

Physicians must also be kept in the loop about the possible uncertainties of the chatbot and its diagnoses, such that they can avoid worrying about potential inaccuracies in the outcomes and predictions of the algorithm. “What doctors often need is wisdom rather than intelligence, and we are a long way away from a science of artificial wisdom.” Chatbots lack both wisdom and the flexibility to correct their errors and change their decisions. For all their apparent understanding of how a patient feels, they are machines and cannot show empathy. They also cannot assess how different people prefer to talk, whether seriously or lightly, keeping the same tone for all conversations.

Types of Chatbots and Their Applications

AI text bots helped detect and guide high-risk individuals toward self-isolation. The technology helped the University Hospitals system used by healthcare providers to screen 29,000 employees for COVID-19 symptoms daily. This enabled swift response to potential cases and eased the burden Chat PG on clinicians. Now, let’s explore the main applications of artificial intelligence chatbots in healthcare in more detail. Patients suffering from mental health issues can seek a haven in healthcare chatbots like Woebot that converse in a cognitive behavioral therapy-trained manner.

Do medical chatbots powered by AI technologies cause significant paradigm shifts in healthcare? The systematic literature review and chatbot database search includes a few limitations. The literature review and chatbot search were all conducted by a single reviewer, which could have potentially introduced bias and limited findings. In addition, our review explored a broad range of health care topics, and some areas could have been elaborated upon and explored more deeply.

The Role of Artificial Intelligence

To develop social bots, designers leverage the abundance of human–human social media conversations that model, analyse and generate utterances through NLP modules. However, the use of therapy chatbots among vulnerable patients with mental health problems bring many sensitive ethical issues to the fore. Chatbots are software programs that use artificial intelligence and natural language processing to have personalized conversations with human users, either by text or voice. In healthcare, chatbots are being applied to automate conversations with patients for numerous uses – we‘ll cover the major ones shortly. A total of 30% (30/100) of participants indicated that they had direct personal experience with the use of chatbots for health-related issues. Physicians were also given a list of currently available health care chatbots, to examine their familiarity with some of the interfaces that could be potentially accessed by patients.

Questions were varied between easy, medium, and hard, as well as a combination of multiple-choice, binary, and descriptive questions. In 1999, I defined regenerative medicine as the collection of interventions that restore to normal function tissues and organs that have been damaged by disease, injured by trauma, or worn by time. I include a full spectrum of chemical, gene, and protein-based medicines, cell-based therapies, and biomechanical interventions that achieve that goal.

In practice, ‘chatbot expertise’ has to do with, for example, giving a correct answer (provision of accurate and relevant information). The importance of providing correct answers has been found in previous studies (Nordheim et al. 2019, p. 25), which have ‘identified the perceived ability of software agents as a strong predictor of trust’. Conversely, automation errors have a negative effect on trust—‘more so than do similar errors from human experts’ (p. 25). However, the details of experiencing chatbots and their expertise as trustworthy are a complex matter. As Nordheim et al. have pointed out, ‘the answers not only have to be correct, but they also need to adequately fulfil the users’ needs and expectations for a good answer’ (p. 25). Importantly, in addition to human-like answers, the perceived human-likeness of chatbots in general can be considered ‘as a likely predictor of users’ trust in chatbots’ (p. 25).

What are Chatbots in the Healthcare Industry?

Before designing a conversational pathway for an AI driven healthcare bot, one must first understand what makes a productive conversation. Before chatbots, we had text messages that provided a convenient interface for communicating with friends, loved ones, and business partners. In fact, the survey findings reveal that more than 82 percent of people keep their messaging notifications on. Forksy is the go-to digital nutritionist that helps you track your eating habits by giving recommendations about diet and caloric intake. This chatbot tracks your diet and provides automated feedback to improve your diet choices; plus, it offers useful information about every food you eat – including the number of calories it contains, and its benefits and risks to health. Once the fastest-growing health app in Europe, Ada Health has attracted more than 1.5 million users, who use it as a standard diagnostic tool to provide a detailed assessment of their health based on the symptoms they input.

These chatbots are trained on healthcare-related data and can respond to many patient inquiries, including appointment scheduling, prescription refills, and symptom checking. Healthbots are computer programs that mimic conversation with users using text or spoken language9. The advent of such technology has created a novel way to improve person-centered healthcare. The underlying technology that supports such healthbots may include a set of rule-based algorithms, or employ machine learning techniques such as natural language processing (NLP) to automate some portions of the conversation.

Moreover, training is essential for AI to succeed, which entails the collection of new information as new scenarios arise. However, this may involve the passing on of private data, medical or financial, to the chatbot, which stores it somewhere in the digital world. Also, if the chatbot has to answer a flood of questions, it may be confused and start to give garbled answers. At Topflight, we’ve been lucky to have worked on several exciting chatbot projects. The Health Insurance and Portability and Accountability Act (HIPAA) of 1996 is United States regulation that sets the standards for using, handling, and storing sensitive healthcare data. That sums up our module on training a conversational model for classifying intent and extracting entities using Rasa NLU.

The rapid adoption of AI chatbots in healthcare leads to the rapid development of medical-oriented large language models. Yes, many healthcare chatbots can act as symptom checkers to facilitate self-diagnosis. Users usually prefer chatbots over symptom checker apps as they can precisely describe how they feel to a bot in the form of a simple conversation and get reliable and real-time results. Everyone wants a safe outlet to express their innermost fears and troubles and Woebot provides just that—a mental health ally. It uses natural language processing to engage its users in positive and understanding conversations from anywhere at any time.

Health promotion use, such as lifestyle coaching, healthy eating, and smoking cessation, has been one of the most common chatbots according to our search. In addition, chatbots could help save a significant amount of health care costs and resources. Newer therapeutic innovations have come with a heavy price tag, and out-of-pocket expenses have placed a significant strain on patients’ financial well-being [23].

They are programmed to provide patients with accurate and relevant health-related data. Beyond triage, chatbots serve as an always-available resource for patients to get answers to health questions. Monitor user feedback chatbot in healthcare and analytics data to identify areas for improvement and make adjustments accordingly. And then, keep the chatbot updated with the latest medical knowledge and guidelines to ensure accuracy and relevance.

Furthermore, Rasa also allows for encryption and safeguarding all data transition between its NLU engines and dialogue management engines to optimize data security. As you build your HIPAA-compliant chatbot, it will be essential to have 3rd parties audit your setup and advise where there could be vulnerabilities from their experience. Using these safeguards, the HIPAA regulation requires that chatbot developers incorporate these models in a HIPAA-complaint environment. This requires that the AI conversations, entities, and patient personal identifiers are encrypted and stored in a safe environment.

Mental Health Support

Bots also do not get sick or tired, and they can be up and running 24 h per day. This relieving of pressure on contact centres is especially important in the present COVID-19 situation (Dennis et al. 2020, p. 1727), thus making chatbots cost-effective. However, one of the key elements for bots to be trustworthy—that is, the ability to function effectively with a patient—‘is that people believe that they have expertise’ (Nordheim et al. 2019).

• Since the 1950s, there have been efforts aimed at building models and systematising physician decision-making.
• That sums up our module on training a conversational model for classifying intent and extracting entities using Rasa NLU.
• Furthermore, if there was a long wait time to connect with an agent, 62% of consumers feel more at ease when a chatbot handles their queries, according to Tidio.
• Healthcare professionals can’t reach and screen everyone who may have symptoms of the infection; therefore, leveraging AI health bots could make the screening process fast and efficient.
• They are designed to simulate human-like conversation, enabling patients to interact with them as they would with a real person.
• This “AI-powered health assistant” will integrate seamlessly with each care team to fully support the patient‘s physical, mental, social and financial health needs.

And there are many more chatbots in medicine developed today to transform patient care. If you think of a custom chatbot solution, you need one that is easy to use and understand. This can be anything from nearby facilities or pharmacies for prescription refills to their business hours. Let’s check how an AI-driven chatbot in the healthcare industry works by exploring its architecture in more detail.

With the eHealth chatbot, users submit their symptoms, and the app runs them against a database of thousands of conditions that fit the mold. This is followed by the display of possible diagnoses and the steps the user should take to address the issue – just like a patient symptom tracking tool. This AI chatbot for healthcare has built-in speech recognition and natural language processing to analyze speech and text to produce relevant outputs. To develop a chatbot that engages and provides solutions to users, chatbot developers need to determine what types of chatbots in healthcare would most effectively achieve these goals. Therefore, two things that the chatbot developer needs to consider are the intent of the user and the best help the user needs; then, we can design the right chatbot to address these healthcare chatbot use cases.

• Chatbot apps were downloaded globally, including in several African and Asian countries with more limited smartphone penetration.
• Key areas of focus are safety, effectiveness, timeliness, efficiency, equitability, and patient-centered care [20].
• We provide companies with senior tech talent and

  product development expertise to build world-class software.

• The healthbots serve a range of functions including the provision of health education, assessment of symptoms, and assistance with tasks such as scheduling.

There are three primary use cases for the utilization of chatbot technology in healthcare – informative, conversational, and prescriptive. These chatbots vary in their conversational style, the depth of communication, and the type of solutions they provide. Healthcare providers must ensure that chatbots are regularly updated and maintained for accuracy and reliability. Chatbots ask patients about their current health issue, find matching physicians and dentists, provide available time slots, and can schedule, reschedule, and delete appointments for patients. Chatbots can also be integrated into user’s device calendars to send reminders and updates about medical appointments. Conversational chatbots with different intelligence levels can understand the questions of the user and provide answers based on pre-defined labels in the training data.

Dennis et al. (2020) examined ability, integrity and benevolence as potential factors driving trust in COVID-19 screening chatbots, subsequently influencing patients’ intentions to use chatbots and comply with their recommendations. They concluded that high-quality service provided by COVID-19 screening chatbots was critical but not sufficient for widespread adoption. https://chat.openai.com/ The key was to emphasise the chatbot’s ability and assure users that it delivers the same quality of service as human agents (Dennis et al. 2020, p. 1727). Their results suggest that the primary factor driving patient response to COVID-19 screening hotlines (human or chatbot) were users’ perceptions of the agent’s ability (Dennis et al. 2020, p. 1730).
