Digital therapeutics, a subset of digital health, are evidence-based therapeutic interventions driven by high quality software programs to prevent, manage, or treat a medical disorder or disease. [1] [2] [3] [4] [5] Digital therapeutic companies should publish trial results inclusive of clinically meaningful outcomes in peer-reviewed journals. [6] The treatment relies on behavioral and lifestyle changes usually spurred by a collection of digital impetuses. [3] [7] Because of the digital nature of the methodology, data can be collected and analyzed as both a progress report and a preventative measure. [8] [9] [10] [11] [12] [13] Treatments are being developed for the prevention and management of a wide variety of diseases and conditions, including type 1 & type II diabetes, congestive heart failure, obesity, Alzheimer's disease, dementia, asthma, substance abuse, ADHD, hypertension, anxiety, depression, and several others. [2] [14] [15] [16] [17] Digital therapeutics often employ strategies rooted in cognitive behavioral therapy. [18] [19] [20]
Although digital therapeutics can be employed in numerous ways, the term can broadly be defined as a treatment or therapy that utilizes digital and often Internet-based health technologies to spur changes in patient behavior. [4] [21] The use of digital products to improve health outcomes dates as far back as 2000. [9] [3] The term itself has been in use since around 2012. [22] The first mention of the term in a peer-reviewed research publication was in 2015, in which Dr. Cameron Sepah formally defined the field as: "Digital therapeutics are evidence-based behavioral treatments delivered online that can increase accessibility and effectiveness of health care." [3] Digital therapeutics can be used as a standalone therapy or in conjunction with more conventional treatments like pharmacological or in-person therapy. [4] [18] As of 2018, digital therapeutics continues to be an evolving field that medical professionals, students, and patients are beginning to utilize. [23]
The Digital Therapeutics Alliance states: "Digital therapeutics (DTx) deliver evidence-based therapeutic interventions to patients that are driven by high quality software programs to prevent, manage, or treat a broad spectrum of physical, mental, and behavioral conditions." [24] Digital therapeutics are different from wellness apps or medication reminders in that they require rigorous clinical evidence to substantiate intended use and impact on disease state.
It is often used as a preventive measure for patients who are at risk of developing more serious conditions. For instance, a patient with prediabetes may be prescribed digital therapeutics as a method to change their diet and behavior that could otherwise lead to a diabetes diagnosis. [3] [2] [15] [20] Digital therapeutics can also be used as a treatment option for existing conditions. For instance, a patient with type II diabetes can use digital therapeutics to manage the disease more effectively. [2] [3] [15]
The methodology uses a variety of digital implements to help manage, monitor, and prevent illnesses in at-risk patients. These include mobile devices and technologies, apps, sensors, desktop computers, and various Internet of Things devices. [25] These implements can collect a wide variety of data, ranging from big to small. Digital therapeutics can theoretically collect a high volume of data from a variety of sources. It also collects "smaller" data, "capturing personalized physiological parameters, behavior patterns and social and geographical patterns that can be recorded from multiple digital sources." [8]
Digital therapeutics can be used for a variety of conditions. There is no single methodology used in the practice of digital therapeutics. Many approaches use methods based upon cognitive behavioral therapy to spur patients to make lifestyle changes, reinforced with gamification, peer support, and in some cases telehealth such as coaching or psychotherapy. The method can be used to manage and improve outcomes in numerous conditions, including type II diabetes, Alzheimer's disease, dementia, congestive heart failure, chronic obstructive pulmonary disease, asthma, lung disease, obesity, substance abuse, ADHD, insomnia, hypertension, anxiety, depression, and others. [2] [16] [17] [11]
Methodologies can be as simple as psychoeducation or sending notifications designed to alter behavior to patients who are at risk of obesity or diabetes [15] [2] and as complex as administering an ingestible radio tag that communicates with an external sensor to monitor the efficacy of a given medication. [4] Diabetes and obesity prevention and management is a major focus in the field of digital therapeutics. [26] [10] Connected devices like insulin pumps, blood glucose meters, and wearable devices can all send data to a unified system. The therapy also uses self-reported data like diet or other lifestyle factors. [2] [3] It is also often used to monitor the potential for heart and lung conditions and change behaviors like smoking, poor diet, or a lack of exercise. [25] [2]
Digital therapeutics can also be used to treat patients with psychological and neurological symptoms. For example, patients with disorders like ADHD, depression, and anxiety can receive cognitive behavioral therapy via their mobile devices. [18] One study looked at the efficacy of avatar-based therapeutic interventions to reduce depressive symptoms. [14] There is also evidence of how Avatar therapy can help in reducing the distress caused by voices in schizophrenia. [27] [28] Another study analyzed seven clinical trials to demonstrate the efficacy of a digital therapeutic in significantly reducing blood pressure. [16] A preliminary study suggested that a mobile mindfulness app may be able to decrease acute stress while improving mood. [29]
The general consensus among researchers in the field of digital therapeutics is that the discipline requires more clinical data and investigation to be fully evaluated. [3] [23] A variety of studies have been conducted to evaluate the efficacy and impact of behavior change techniques that utilize a digital platform, however. [3] [11] [26] In a meta-analysis of 85 such studies comprising a total sample size of over 43,000 participants, researchers discovered that digital therapeutics have a "statistically small but significant effect on health-related behavior." The study also showed that a broader use of theory, behavior change techniques, and modes of delivery (especially regular notifications) improved the efficacy of a given program. [3]
Individual studies have also showed some benefits for patients. For instance, a diabetes prevention program using digital therapeutics saw participants lose an average of 4.7% of baseline body weight after 1 year (4.2% after 2 years) and undergo a 0.38% reduction in A1c levels after 1 year (0.43% after 2 years). [3] Another weight loss pilot program using digital therapeutics reported a mean weight loss of 13.5 pounds (or 7.3% of baseline) with a significant average drop in both systolic and diastolic blood pressure (18.6 mmHg and 6.4 mmHg respectively). The study also saw a slight but statistically insignificant drop in total cholesterol, LDL, triglycerides, and A1c. [26]
That said, the concept of outcomes and impact in the context of digital therapeutics is generally defined broader than strictly health outcomes. [30] A recent review of 244 studies highlighted that, on top of improving health outcomes in certain circumstances as outlined above, the value of digital therapeutics can also arise from improving healthcare access to underserved populations and address health inequalities, or reducing healthcare expenditure. [31] This broader interpretation has also called into question the fitness of traditional health technology assessment frameworks and given rise to calls to develop novel frameworks that embrace the variety of impacts that digital therapeutics can have. [32] [33]
While a broad range of unregulated health apps have historically been available in the App Store (iOS/iPadOS) or Google Play since their launch, many of these have been found to produce inconsistent, misleading, or dangerous results. [34] In response, regulators in the United States such as the Food and Drug Administration have developed regulatory frameworks such as software as a medical device (SaMD) [35] which require manufacturers to prove that their apps are safe, effective, and that rigorous quality management system processes are in place to ensure that remains the case as software updates occur. However, in an assessment of 4,936 apps that fall under the SaMD umbrella in the United States published in 2019, only 105 (2.13%) included a specific summary of their cybersecurity content. [36] While the content of cybersecurity in SaMD devices was observed to be growing in newer SaMD applications, the (perceived) absence of clear cybersecurity measures in the vast majority of SaMD devices remains a substantial barrier for patients and health professionals to start using digital therapeutics in practice. [31]
In the European Union, regulation (EU) 2017/745, commonly known as "EU MDR" classifies potential digital therapeutics in terms of their intended use, application, and potential to cause harm. Because digital therapeutics are increasingly operating within a regulated environment, the degree of documentation and regulatory compliance (such as ISO 13485 or the CE mark) has increased too.
Unlike medication or the billable hours of healthcare professionals, there are not currently clear pathways to reimbursement in most health systems. [35] While many manufacturers seek FDA clearance or approval, this is only the first step on the path to being reimbursed for the use of a DTX. [37] Accordingly, digital therapeutics companies pursue a range of business models:
To help build the business case for their usage, DTx companies often commission health economics evaluations of their interventions to show that their use ultimately lowers healthcare costs in the medium-long term, such as by reducing the need for hospital admissions or expensive surgeries. [37]
Group psychotherapy or group therapy is a form of psychotherapy in which one or more therapists treat a small group of clients together as a group. The term can legitimately refer to any form of psychotherapy when delivered in a group format, including art therapy, cognitive behavioral therapy or interpersonal therapy, but it is usually applied to psychodynamic group therapy where the group context and group process is explicitly utilized as a mechanism of change by developing, exploring and examining interpersonal relationships within the group.
Binge eating disorder (BED) is an eating disorder characterized by frequent and recurrent binge eating episodes with associated negative psychological and social problems, but without the compensatory behaviors common to bulimia nervosa, OSFED, or the binge-purge subtype of anorexia nervosa.
eHealth describes healthcare services which are supported by digital processes, communication or technology such as electronic prescribing, Telehealth, or Electronic Health Records (EHRs). The use of electronic processes in healthcare dated back to at least the 1990s. Usage of the term varies as it covers not just "Internet medicine" as it was conceived during that time, but also "virtually everything related to computers and medicine". A study in 2005 found 51 unique definitions. Some argue that it is interchangeable with health informatics with a broad definition covering electronic/digital processes in health while others use it in the narrower sense of healthcare practice using the Internet. It can also include health applications and links on mobile phones, referred to as mHealth or m-Health. Key components of eHealth include electronic health records (EHRs), telemedicine, health information exchange, mobile health applications, wearable devices, and online health information. These technologies enable healthcare providers, patients, and other stakeholders to access, manage, and exchange health information more effectively, leading to improved communication, decision-making, and overall healthcare outcomes.
In medicine, patient compliance describes the degree to which a patient correctly follows medical advice. Most commonly, it refers to medication or drug compliance, but it can also apply to other situations such as medical device use, self care, self-directed exercises, or therapy sessions. Both patient and health-care provider affect compliance, and a positive physician-patient relationship is the most important factor in improving compliance. Access to care plays a role in patient adherence, whereby greater wait times to access care contributing to greater absenteeism. The cost of prescription medication also plays a major role.
Telerehabilitation (or e-rehabilitation is the delivery of rehabilitation services over telecommunication networks and the internet. Telerehabilitation allows patients to interact with providers remotely and can be used both to assess patients and to deliver therapy. Fields of medicine that utilize telerehabilitation include: physical therapy, occupational therapy, speech-language pathology, audiology, and psychology. Therapy sessions can be individual or community-based. Types of therapy available include motor training exercises, speech therapy, virtual reality, robotic therapy, goal setting, and group exercise.
PatientsLikeMe (PLM) is an integrated community, health management, and real-world data platform. The platform currently has over 830,000 members who are dealing with more than 2,900 conditions, such as ALS, MS, and epilepsy. Data generated by patients themselves are collected and quantified with the goal of providing an environment for peer support and learning. These data capture the influences of different lifestyle choices, socio-demographics, conditions and treatments on a person's health.
mHealth is an abbreviation for mobile health, a term used for the practice of medicine and public health supported by mobile devices. The term is most commonly used in reference to using mobile communication devices, such as mobile phones, tablet computers and personal digital assistants (PDAs), and wearable devices such as smart watches, for health services, information, and data collection. The mHealth field has emerged as a sub-segment of eHealth, the use of information and communication technology (ICT), such as computers, mobile phones, communications satellite, patient monitors, etc., for health services and information. mHealth applications include the use of mobile devices in collecting community and clinical health data, delivery/sharing of healthcare information for practitioners, researchers and patients, real-time monitoring of patient vital signs, the direct provision of care as well as training and collaboration of health workers.
The use of electronic and communication technologies as a therapeutic aid to healthcare practices is commonly referred to as telemedicine or eHealth. The use of such technologies as a supplement to mainstream therapies for mental disorders is an emerging mental health treatment field which, it is argued, could improve the accessibility, effectiveness and affordability of mental health care. Mental health technologies used by professionals as an adjunct to mainstream clinical practices include email, SMS, virtual reality, computer programs, blogs, social networks, the telephone, video conferencing, computer games, instant messaging and podcasts.
Empagliflozin, sold under the brand name Jardiance, among others, is an antidiabetic medication used to improve glucose control in people with type 2 diabetes. It is taken by mouth.
Digital health is a discipline that includes digital care programs, technologies with health, healthcare, living, and society to enhance the efficiency of healthcare delivery and to make medicine more personalized and precise. It uses information and communication technologies to facilitate understanding of health problems and challenges faced by people receiving medical treatment and social prescribing in more personalised and precise ways. The definitions of digital health and its remits overlap in many ways with those of health and medical informatics.
Childhood chronic illness refers to conditions in pediatric patients that are usually prolonged in duration, do not resolve on their own, and are associated with impairment or disability. The duration required for an illness to be defined as chronic is generally greater than 12 months, but this can vary, and some organizations define it by limitation of function rather than a length of time. Regardless of the exact length of duration, these types of conditions are different than acute, or short-lived, illnesses which resolve or can be cured. There are many definitions for what counts as a chronic condition. However, children with chronic illnesses will typically experience at least one of the following: limitation of functions relative to their age, disfigurement, dependency on medical technologies or medications, increased medical attention, and a need for modified educational arrangements.
An activity tracker is an electronic device or app that measures and collects data about an individual's movements and physical responses, towards the goal of monitoring and improving their health, fitness, or psychological wellness over time.
Health information on the Internet refers to all health-related information communicated through or available on the Internet.
Infodemiology was defined by Gunther Eysenbach in the early 2000s as information epidemiology. It is an area of science research focused on scanning the internet for user-contributed health-related content, with the ultimate goal of improving public health. Later, it is also defined as the science of mitigating public health problems resulting from an infodemic.
Joseph Antony Cafazzo is a Canadian biomedical engineer, educator, and researcher.
Digital medicine refers to the application of advanced digital technologies, such as artificial intelligence, machine learning, and big data analytics, to improve patient outcomes and healthcare delivery. It involves the integration of technology and medicine to facilitate the creation, storage, analysis, and dissemination of health information, with the aim of enhancing clinical decision-making, improving patient care, and reducing costs.
Lark Health is an American digital health company based in Mountain View, California. It provides a 24/7 nursing platform for chronic conditions, powered by artificial intelligence (AI) and has a text-messaging type interface. Lark also provides AI nurses for type 2 diabetes care, hypertension care, tobacco cessation, stress management, obesity, and more for 1.5 million patients.
Internet-based treatments for trauma survivors is a growing class of online treatments that allow for an individual who has experienced trauma to seek and receive treatment without needing to attend psychotherapy in person. The progressive movement to online resources and the need for more accessible mental health services has given rise to the creation of online-based interventions aimed to help those who have experienced traumatic events. Cognitive behavioral therapy (CBT) has shown to be particularly effective in the treatment of trauma-related disorders and adapting CBT to an online format has been shown to be as effective as in-person CBT in the treatment of trauma. Due to its positive outcomes, CBT-based internet treatment options for trauma survivors has been an expanding field in both research and clinical settings.
Digital health interventions, or digital healthcare interventions, commonly referenced as DHIs in scientific articles, have emerged as a alternative in healthcare that may enable improved health outcomes, increase healthcare delivery, and empower patients. Commonly, it offers options to provide treatments, monitor health conditions, assist patients, and enable healthcare professionals to extend their services. Health mobile applications have become more popular - as mentioned by Butcher and Hussain, in 2022, more than 100,000 healthcare mobile applications were offered in Apple and Google app stores. These interventions may utilise various digital technologies and applications, besides mobile apps and websites, and they may comprehend wearables, biosensors, and Internet of Things
