Who is this product intended to be used for? Patients and clinical workforce.
What is the product designed to do and how is it used? Concentric is a digital consent to treatment (aka econsent) application that is used in place of traditional paper consent forms. Concentric supports clinicians and patients with evidence-based information that can be personalised to the individual. Consent information is made available to patients outside their consultation, including the ability to give consent remotely where appropriate.
What are the intended or proven benefits for users?
Consent process flexibility - Consent process becomes more flexible and adaptable to the needs of the individual and the system, including access over time, access from anywhere, and remote consent functionality through an intuitive application.
Consent information personalisation - Consent information can be easily adapted and personalised to the individual.
Integration delivering joined-up care - Integration of the consent process into other systems to deliver joined-up care, including (where available) a main electronic health record (EHR) and patient held record (PHR).
Trusted content across all specialties - Standardised, evidence-based information and risk profiles - including COVID-19 risks - across over 1,200 operations, procedures and treatments to support use across the organisation as the default mechanism of consent. Trusted across multiple NHS and private sector organisations.
Supporting best practice - Support in meeting best practice consent processes through visibility of process (e.g rate of consent on the day of surgery), and nudges (e.g personalisation of information and documenting personalised notes).
Reduced clinical errors - Reduced risk of wrong site surgery and patient identification errors through legible consent PDF’s.
Accessible from anywhere - Cloud-based, integrated system meaning that the clinical consent record can be accessed and amended from anywhere without the need for complex paper logistics.
Full audit trail, cryptographically secured - Full audit trail maintained and available for each consent episode, including any customisations, when information was shared, when consent was given etc. Advanced cryptography ensures that the audit trail cannot be tampered with and the state of the episode at each stage can be demonstrated.
Advanced Electronic Signature - The patient signature recorded within Concentric is classed as an advanced electronic signature by eIDAS UK regulation and is fully admissible in a court of law.
Improved clinician experience and wellbeing - Improved clinician experience of the consent process, including the ability to deal with complex clinical scenarios (e.g combined procedures). Improved clinician wellbeing due to reduced clinical risk associated with the consent process.
Saves clinicians time - Reduced consent process administration time due to integration with patient demographics, document storage, and user authentication, an intuitive application and procedure-specific templates.
Reduced day-of-surgery cancellations and delays - Increased completion of consent prior to the day of surgery (supported by remote consent) and improved visibility of the consent status within Concentric and the EHR reduces day of surgery delays and cancellations.
Reduced medico-legal risk from lost forms - The risk of losing legal consent forms is removed with a digital process.
Reduction to near zero use of paper for consent forms and information leaflets - Use of paper, both carbon-copy consent forms and paper information leaflets can be reduced, with paper copies printed only where necessary for a patient without digital access.

Summary from Pen Test Partners Web Application Security Assessment conducted between the 18th and 24th November 2022:
Concentric Health Limited (Concentric) required Pen Test Partners (PTP) to conduct a web application assessment of their Concentric platform, an application which manages the consent flow between clinicians and patients for medical interventions. The testing was conducted in line with PTP’s standard methodology which is based on the Open Web Application Security Project (OWASP) web application security guidelines. The Concentric application was found to be well secured from both an authenticated and unauthenticated perspective, with clear implementation of security best practice throughout. The main concern facing the application relates to disclosure of sensitive patient information to unauthorised parties, for which no attack vector was identified during the engagement. Concentric should consider the findings presented in this report for implementation to continue to improve the application’s security posture.
Please confirm whether all custom code had a security review: Yes, internal code review
Please confirm whether all privileged accounts have appropriate Multi-Factor Authentication (MFA)? Yes
Please confirm whether logging and reporting requirements have been clearly defined: Yes
Please confirm whether the product has been load tested: Yes
Does your product expose any Application Programme Interfaces (API) or integration channels for other consumers? Yes - details relating to our integrations, including FHIR integrations are found within this publicly available integration documentation.
Do you use NHS number to identify patient record data? Yes
- Is this done via NHS Login? No
- If no, please set out the rationale, how your product establishes NHS number, and the associated security measures in place: Secure integrations are put in place between Concentric and the PAS database for the healthcare organisation, including search by NHS number where available. For patient access, a secure link is shared with the patient and authenticated with the patient’s date of birth. Read more about our authentication approach.
Does your product have the capability for read/write operations with electronic health records (EHRs) using industry standards for secure interoperability? Yes. Industry standard approaches for secure interoperability are preferred, such as FHIR API’s for patient demographics and document storage. Regarding data security in transit, web and API servers only allow requests made using TLS version 1.2 or above, which provides protection against snooping and man in the middle attacks on data. Non-HTTPS requests are denied by API servers.
Is your product a wearable or device, or does it integrate with them? No
Usability and accessibility
Understand users and their needs in context of health and social care
Do you engage users in the development of the product? Yes, in the following ways:
User research: Throughout development and live use, user research insights - both patient and clinician - have driven development decisions. Patient and clinician insights from Autumn 2020 user interviews are described in this summary document.
Patient feedback: If wished by the healthcare organisation (as the data controller) a digital patient feedback survey is sent to all patients 2 weeks following consent to get their feedback on experience, ease of use, quality of information, and areas for improvement. Approximately 2000 patient feedback responses have been received in the past 12 months (average overall experience = 9/10), and directly input into sprint planning. Patient feedback can also be shared within the application at any time.
Clinician feedback: Collected within the application and feedback survey sent out at intervals, asking for feedback on overall experience, preference compared to paper process, perceived quality of consent process compared to paper process, and any areas of improvement.
Publications: The Concentric team, alongside academics, have published findings relating to the problems of traditional paper-based consent processes, and early work demonstrating the impact of introducing digital consent. Examples include:
- Assessment of the introduction of semi-digital consent into surgical practice - BJS
- Completion of hand-written surgical consent forms is frequently suboptimal and could be improved by using electronically generated, procedure-specific forms - Surgeon
- Surgical consent: the world’s largest Chinese Whisper? A review of current surgical consent practices - BMJ Medical Ethics
Search data and analytics: Real world use of the product is monitored to guide improvements in product, content, and process. Examples include:
- Consent statistics demonstrating use of ‘on the day’ consent, guiding quality improvement programmes.
- Custom modifications to templates allowing content review based on real-world use.
- ‘No treatment search results’ allowing addition of missing but required content.
Work towards solving a whole problem for users
- Are all key user journeys mapped to ensure that the whole user problem is solved or it is clear to users how it fits into their pathway or journey? Concentric has a clear role in the treatment pathway, with consent being a required step prior to undergoing invasive treatment. Clinicians initiate a Concentric episode for patients, and share the information with patients during or following a consultation. A system map was developed during development to ensure consideration of all key user journeys.
Make the service simple to use
- Do you undertake user acceptance testing to validate usability of the system? Patients are routinely asked at post-consent for their feedback on the usability of the system. Quality assurance testing is undertaken on all common browsers prior to each release and Concentric is a responsive web application with all functionality available across all screen sizes. The following are usability testing results from patients at one healthcare organisation over the past 12 months.
