The three challenges for digital health in 2017 – and how we solved them

Tackling data security, digital health requirements and the data stream.

In a previous post we highlighted the wealth of knowledge and research already available from academic studies that support the case for using digital technologies to deliver new services that improve health outcomes for patients.

It states that a key challenge for healthcare industry now is to apply this knowledge effectively in the form of new digitally enabled health services.

The data firehose

Using connected devices and hardware, it is now possible to measure almost every part of human physiology. The range of wearable technologies has continued to expand over the last few years with sensors in our shoes, clothing and even ears.

Wearable technology that gathers real time data on physiology of individuals is expanding to a more general “sensorification” of the physical world. The connected home is a by product of this trend with the likes of Alexa and Hive becoming popular. Many organisations are also now seeing the value of IoT to help support social care delivery.

It is clear that connected hardware and sensors can help transform the delivery of health and social care services to become more continuous and preventative rather than episodic and reactive.

In this post, we will highlight the some of the problems we have encountered when operationalising and scaling these new type of services across the UK health service.


Three challenges for digital health & social care services

The three big challenges for digital health services in 2017 can be broken down into the need to:

  1. Securely store and share data generated by patients with health professionals
  2. Develop new service delivery models that leverage the data but also meet the needs of health professionals
  3. Generate actionable insight over the data stream

In the following section, we explore each of these challenges in turn and highlight how we have tried to address these challenges through the development of Lenus – a new digital health platform.


1. Data sharing

Many of the current solutions attempt to bridge web based systems that generate patient data with internal healthcare systems. This approach is an incremental step and results in unnecessary development effort in trying to connect data captured by patients on digital devices to internal healthcare systems behind firewalls.

The friction this approach generates makes it more difficult to develop digital services that rely on the seamless transfer of data in real time. It also entrenches the status quo by requiring investment to upgrade legacy internal systems to accept this type of data and cope with the increase in load.

A quote from Steven Sinofsky, ex President of Windows at Microsoft, captures the point well:

"History clearly shows that betting on bridge solutions is the fastest way to slow down your efforts and build technical debt that reduces ROI in both the short- and long-term. The reason should be apparent, which is that the architecture that represents the new solution is substantially different — so different, in fact, that to connect old and new means your architectural and engineering efforts will be spent on the seam rather than the functionality. There’s an incredibly strong desire to get more out of existing investments or to find rationale for requiring use of existing implementations, but practically speaking, efforts in that direction will feel good for a short while, and then will leave the product or organization further behind."


How can this challenge be solved?

We believe that the solution to this problem lies in digital health platforms. At Storm, we have therefore worked over the last year to develop Lenus, using the infrastructure and security services available from Microsoft Azure. Lenus offers the requisite digital plumbing to connect patient data with healthcare professionals and is designed to be open in order to support an eco-system of digital health services.

It consists of:

  • A technology infrastructure that offers identity, access and consent management services through standard APIs
  • A data layer that provides encrypted data storage and enforces standards for the exchange of a wide range of health measurements between the platform and service layer

If you are interested in deploying Lenus or connecting your app or service to the platform, please get in touch.

The services constitute three mobile apps for patients that capture and visualise data received from connected hardware devices relating to the different conditions and, using the Lenus platform, shares this data with a web application designed to aggregate the data and augment it with appropriate workflow and actions for healthcare professionals.

3. Insight & prioritisation over the data firehose

The introduction of these types of services will generate a huge amount of data. As such it will be important for services to translate the data streams into knowledge and actionable insight.

Health professionals will quite rightly balk at being exposed to a firehose of real time data from a multitude of different devices. You are unlikely to find a cardiologist who wants to take responsibility for monitoring a stream of ECGs from a group of patients 24hrs a day.

As such, services will increasingly need to use algorithms and machine learning, guided by transparent clinical guidelines, to monitor the data streams, apply rules and offer actionable insight to health professionals.

Increasingly, these services will become more sophisticated and will start to check and parse the data generated to help identify trends and alert both the patient and the health professional much earlier. For example a recent challenge on Kaggle has shown how neural networks can be used to automatically detect lung cancer in chest cavity images. Stanford have recently used similar techniques to automatically identify skin cancer in images.

While we may be some way from full automation it is clear that digital services combined with machine learning can deliver a more efficient triage process and in turn augment the capability of health professionals.


We believe that the three big challenges for digital health can be met with digital health platforms such as Lenus. As demonstrated in this article, the platform’s API first, cloud based solution will allow the creation of new digitally enabled service delivery models that will enhance the capability of health and social care professionals.
