Through remote monitoring, we now see a future for healthcare that is shaped by powerful digital solutions allowing treatments to be tailored specifically to each individual person’s needs, something which was previously unthinkable.

Let us explore how these technologies are revolutionizing patient care.

The power of artificial intelligence in digital therapeutics

By utilizing artificial intelligence data-driven decision making as well as predictive analytics, these digital health solutions have created vast opportunities for both patients and providers when it comes to informed choices leading them towards better results overall.

Predictive analytics

Predictive analytics plays a crucial role in digital therapeutics by leveraging data and artificial intelligence techniques to forecast outcomes, identify patterns, and provide personalized interventions. This advanced tool relies on past data sets combined with statistical algorithms and machine learning methods in order to predict future trends or occurrences.

The Statista’s report Perceived benefits of predictive analytics in clinical settings worldwide in 2022 shows that 72 percent of healthcare professionals in leadership positions expressed their belief that predictive analytics would yield beneficial effects on patient health outcomes within clinical environments. Similarly, 72 percent of respondents anticipated an enhancement in the patient experience through the implementation of predictive analytics in healthcare.

The other areas are:

  • Staff experience
  • Cost of care
  • Population health management
  • Health inequality
  • Value-based care

Predictive analytics can be used in the field of digital therapeutics, among others, in the following areas:

  • Treatment response prediction
  • Disease progression modeling
  • Risk stratification

Harnessing machine learning for improved patient outcomes

The positive outcomes of applying machine learning in the field of medicine are confirmed with clinical evidences. Notably, the utilization of ML technology in addressing conditions like type 2 diabetes has yielded concrete and lasting improvements concerning blood pressure, BMI, inflammation levels, and liver function.

Let's examine the potential applications of machine learning in the field of digital therapeutics.

Pattern recognition

Pattern recognition is a means of employing machine learning to recognize patterns and consistencies in data. By recognizing trends and associations within patient details, healthcare professionals are able to get a clearer picture of medical conditions as well as create more effective treatment plans.

This automated form of analyzing information has plenty of practical uses such as image identification up to voice authentication, all for improving the quality care that digital health can provide in this day and age.

When it comes to technical aspect of image recognition, image processing systems can be put to work in the analysis:

  • Image pre-processing – That's where images are resized and adjusted along with other aspects such as contrast or brightness.
  • Image segmentation – ML specialists segment images using tools such as binary masks and edge detection.
  • Feature extraction – This is where the specialists extract geometric properties of segmented lesions such as Area, Perimeter, Greatest Diameter, Circularity Index, Irregularity Index.
  • Classification – k-nearest neighbor algorithms (k-NN) and support vector machines (SVM) are used to enable image classification.

Sophisticated image processing systems are combined with classical machine learning algorithms: k-Nearest Neighbours (k-NN) and Support Vector Machines (SVM). Both can be used as binary classification tools for, among others, skin cancer.

Adaptive treatment strategies

By making use of machine learning algorithms such as RNN-based or transformer-based encoder–decoder structured models for analyzing time series data in the field of digital therapeutics, the treatments are optimized.

Consequently, it is possible to adjust therapies depending on patient progress and response so that every person gets a unique treatment tailored specifically for their needs, which will dynamically evolve over time:

  • Personalized treatment selection
  • Outcome prediction
  • Dynamic treatment adjustment
  • Sequential decision making
  • Side effect prediction
  • Adaptive clinical trials

AI-driven adaptive treatment use case

The study published in European Psychiatry Journal on AI-driven adaptive treatment strategies in internet-delivered CBT aimed to assess the accuracy of machine learning algorithms in predicting treatment outcomes for individual patients receiving Internet-delivered Cognitive Behavioural Therapy (ICBT).

Data from over 6000 patients with depression, panic disorder, or social anxiety disorder were used. Eight different machine learning methods were trained using various data sources, including symptom measures, therapist-patient messages, and homework reports.

The results showed that the machine learning algorithms consistently outperformed chance-level predictions, with accuracy ranging from 56% to 77%. These algorithms performed better than a previous Adaptive Treatment Strategy trial. The study concluded that machine learning algorithms surpassed the predictive capabilities of the previous strategy, even without therapist input.

The next steps involve visualizing key contributing factors and further improving predictive power using techniques like Ensemble Learning.

These findings indicate the potential of machine learning in predicting treatment outcomes and enhancing Adaptive Treatment Strategies in ICBT.

The role of mHealth apps in digital therapeutics

Mobile apps are another digital therapeutic products that have the capability in making health care services more accessible and encouraging greater patient engagement.

Through these mHealth applications, individuals can easily access medical information without needing an appointment, lessening the need for face-to-face interaction with doctors.

Mobile app technology empowers patients to take charge of their well-being, resulting in improved outcomes and reduced healthcare expenses. mHealth is widely used in wellness and fitness apps, providing users with personalized health coaching and support for their mental well-being.

The anticipated size of the mobile health apps market in the United States is estimated that the overall market for mHealth apps will surpass 50 billion U.S. dollars by 2025. This projection represents a substantial growth compared to the approximate value of two billion dollars recorded in 2016.

When it comes to other countries, mobile applications user share in select countries 2022, India and China emerge as the clear frontrunners, holding a significant market share of 70 percent and 66 percent respectively.
