Technology for RPA

Reference architecture

Each RPA vendor has their own nuances and varied nomenclature, but all products comprise of three fundamental elements such as RPA development tools, robotic control centre and RPA run time.

The components shown are described in more detail as follows.

1. RPA development tools

Recorder: The recorder is the part of the development studio that developers use to configure the robots. It is like the macro recorder in excel, the bot recorder in any platform, records steps. It records mouse and keyboard movements on the user interface (UI) and this recording can be replayed to do the same steps again and again. This enables rapid automation.

Extension and plugins: Most platforms offer many plugins and extensions to ease the development and running of bots. In many applications, such as EPR or oracle finance , it is not easy to individually identify controls of the UI through traditional techniques. RPA vendors have developed plugins and extensions to help with these issues.

Workflow designer: The workflow designer is used by developers to create robot configuration or train the robots. Using the development studio, a set of instructions and decision-making logic is coded for robots to execute. Some platforms provide flow-charting capabilities such as Visio, so it becomes very easy to plot steps in a process, whereas some other platforms require coding. In most studios, in order to do commercial development, developers need to have a fair amount of knowledge of programming – for example, loops and variable assignment amongst others.

2. Robot control centre

Robot control centre provides robot management capabilities. It monitors and controls a robot's operation in a network. It can be used to start/stop robots, make schedules for them, maintain and publish code, redeploy robots to different tasks, and manage licenses and credentials.

3. RPA run time

Once issued their instructions, the software robots (also referred to as “clients” or “agents”) carry them out, interacting directly with enterprise applications to process transactions. The list of actions that a robot is capable of performing can be provided out of the box or actions can often be custom created using code.

Additional components include:

Security

A set of tools to support compliance or any regulatory requirements and provide audit of actions taken and decisions made.

Enterprise applications

The applications, including EPR, finance, procurement, other clinical and non-clinical systems, that belong to the organisations which are integrated with RPA for workflow orchestration.

Technical requirements

Choosing the right tool

There are various RPA tools in the market, at a high level, preferred tools should have the following characteristics:

Ease of use

Tools should not be restricted to only users with technical skills, they should be versatile enough to be usable by clinical, operational and technical users. These tools should also have the capability to collect data that empowers leaders to make informed decisions.

Scalable

Teams will benefit from choosing an RPA platform that can be easily centrally managed and rapidly scaled to as many different locations as necessary.

Reliable

As RPA will automate key tasks and processes, its critical for the teams to consider the reliability of the solution and built-in monitoring with analytics.

Faster implementation

The best tool will let the teams design and test new robotic processes very rapidly. The tools should also have the ability to act on initial performance feedback quickly to optimise the bots.

Smart

The best tools support simple, task-based activities, read and write to any data source, and utilise advanced learning to improve future automations.

Key attributes

Compliance requirements

NHS specific compliance requirements that need to be considered for any RPA implementations are as follows:

Medical device regulation

The 2002 UK Medical Device Regulations apply to all products qualifying as a medical device or in vitro diagnostic medical device (henceforth we mean both by ‘medical device’). All digital technologies classed as medical devices must meet the relevant requirements of the regulation and have a UK Conformity Assessed (UKCA) mark in place before they can be placed on the UK market, please note that an up-to-date CE mark will continue to be recognised until 30 June 2023. The Medicines and Healthcare Products Regulatory Agency’s (MHRA) medical devices flowchart helps developers of digital health technologies understand if their technology is considered a medical device under the 2002 UK Medical Device Regulation.

It is the responsibility of the legal manufacturer to determine if the implementation of automation falls within scope of the above regulations. Assessment of whether an automation qualifies as a medical device or not can be complex and must take into account the wider context of the automated process. Additionally, this assessment is made more complicated, as automation that utilises a known medical device may then themselves be an accessory to a medical device. It is advised that trusts contact their compliance or medical physics/clinical engineering department for clarification. In case of uncertainty, please contact the MHRA.

Clinical risk management

NHS digital information standards on clinical risk management in digital systems is designed to help health and care organisations assure the clinical safety of their health IT software. These standards provide a set of requirements to promote and ensure the effective application of clinical risk management by:

  • health organisations that are responsible for the deployment, use, maintenance and decommissioning of health IT system (DCB0160); and
  • manufacturers that are responsible for development and maintenance of health IT Systems for use within the health and care environment (DCB0129)
NHS digital technology assessment criteria

NHS Digital Technology Assessment Criteria for health and social care (DTAC) gives staff, patients and citizens confidence that the digital health tools they use meet clinical safety, data protection, technical security, interoperability and usability and accessibility standards.

NHS identity and access management

Any RPA deployment involving NHS Spine must use APIs or the NHS’s PKI based identity management capability (approximately 900,000 smart card users) which handles identities for real people based on international PKI standards.

NHS Digital RA and Cyber Security have developed an assessment framework to enable each RPA deployment solution request to be assessed on a case-by-case basis for RA and Information Security Controls. If the controls and risk and mitigation assessments are considered satisfactory, a time limited deployment will be agreed as an exception to NHS RA Policy.

Information governance

Information governance requirements are specific to each trust or local authority, which may include completing data protection impact assessments (DPIA) for each technology being commissioned.
