Data Sources and Accuracy Notice
Version 1.0 | Effective date: 21/09/2026
MedTech Compass brings together NHS and related information to support business and professional analysis of reimbursement, activity, comparable products, innovation pathways and the wider healthcare market. It is an independent decision support service operated by Health Analytical Solutions Limited, company number 08843582.
This notice should be read with the SaaS Subscription Terms and Terms of Use, the accepted Order and the licence information for the relevant source. It explains the data and its limitations. It is not a replacement for a source licence, professional advice or the express service commitments in the contract.
1. Data sources
Information is drawn from publicly available datasets, publications and reference materials and, where separately authorised, other licensed sources. Relevant publishers may include NHS England, historic NHS Digital publications, the Department of Health and Social Care, NICE, the Office for National Statistics, devolved health bodies and other recognised organisations. A publisher appearing in this list does not mean that every dataset it publishes is included or licensed for every use.
The relevant source, reference period, publication or release version and applicable qualifications should be read with each dataset or Output. Information about a source can be provided at dataset, module or linked catalogue level. Where a needed source or date is not shown, users should request clarification rather than assume the information is current or unrestricted.
2. Different kinds of information
Source figures reproduce or summarise published information. Derived figures result from calculations, reclassification or combining sources. Mappings and interpretations reflect the rules, assumptions and judgement applied in organising the information. Forecasts or scenarios, where included, describe possible outcomes under stated assumptions and are not observations or guarantees.
A HAS-derived mapping, summary, estimate or visualisation is not an official publisher output merely because it uses official data. A link to an official document identifies that document; it does not make the whole platform or our interpretation official. Changes in assumptions or methods can change derived results.
3. Accuracy and completeness
We exercise reasonable care and skill in sourcing, structuring and presenting information. Nevertheless, we cannot guarantee that every source or Output is complete, accurate, up to date or free from error. Source information may contain omissions, coding differences, reporting delays, inconsistent definitions or revisions. Processing may involve matching, aggregation, rounding and judgement, which can introduce additional limitations.
Coverage may vary by provider, geography, period or category. The absence of a record or a displayed blank does not establish that no activity, product, evidence, funding or service exists. A suppressed or unavailable value must not be treated as zero unless the source expressly defines it that way.
4. Timeliness and version control
A data reference period, a publisher's release date, our refresh date and the date of an export describe different things. A recent platform refresh does not necessarily mean the underlying activity is recent. Updates may occur at different intervals across modules and may await the original publisher's release or validation of a revised source.
Unless the Order expressly says otherwise, there is no guarantee of real-time data or a fixed refresh schedule. A historic export is a snapshot and does not update when the Service changes. Users should preserve the source and version context and check the latest available material before a significant decision.
5. Comparability, boundaries and analytical limits
Before comparing figures, check the unit being counted, inclusion criteria, period, geography, organisation identity, setting and methodology. Episodes, spells, procedures, admissions and individual patients are not interchangeable measures. Different datasets should not be added together where that could double-count the same underlying activity.
Trends may be affected by changes to coding or grouping versions, reporting completeness, organisational mergers, geographical boundaries, service transfers or data definitions. A comparison is not necessarily like for like. Unless expressly described as adjusted, a ranking or comparison should not be assumed to account for case mix, population need, clinical complexity, service configuration or reporting quality.
Estimated demand, unmet need, market size, capacity release or financial opportunity depends on the method and assumptions used. It does not establish that all identified activity is clinically eligible, fundable, accessible or commercially addressable. Correlation and comparative figures do not establish causation or provider quality.
6. Coding, grouping, reimbursement and funding
References to procedure or diagnosis classifications, Healthcare Resource Groups, payment rules, prices and commissioning policies are for orientation and analysis. Correct coding and grouping depend on the clinical record, applicable classification version, coding standards, grouping logic and other case-specific information. A technology name alone is not enough to determine a valid code or payment.
A displayed national price, benchmark or modelled amount is not a guarantee of actual income, cost, profitability, reimbursement eligibility or funding approval. Relevant contractual arrangements, commissioning responsibility, exclusions, adjustments, local agreements and the applicable financial year must be checked with the responsible organisations.
Users must not use the Service to select an inaccurate code, override clinical documentation or claim payment not supported by the applicable rules. Material coding or reimbursement decisions require validation against the relevant current official material and qualified local teams.
7. Evidence, products and innovation pathways
References to products, evidence, policy or NICE material do not constitute endorsement by HAS or a public body. Presence or absence in the platform is not a comprehensive statement about regulatory approval, safety, clinical effectiveness, cost effectiveness, procurement eligibility or commercial availability.
Users should read the relevant current source in full and check its population, indication, setting, conditions and recommendation status. A description of a review route, evidence requirement or innovation pathway does not guarantee a recommendation, adoption, procurement or future funding outcome.
8. Interpretation and appropriate reliance
MedTech Compass supports professional judgement; it does not replace it. Users are responsible for assessing relevance, checking assumptions, validating material findings against current sources and local circumstances, and obtaining specialist clinical, legal, regulatory, reimbursement, procurement or financial advice where appropriate.
Do not rely on an Output as the sole basis for a high-impact decision or represent it to another person as a definitive funding, policy or clinical determination. When sharing a permitted extract, include the context, date, source and qualifications needed to avoid misleading the recipient. A user's own adaptation must be identified as such.
9. Source rights, attribution and reuse
Publicly accessible information is not automatically unrestricted or available for commercial reuse. Source materials can carry copyright, database rights, territorial conditions and restrictions on copying, adaptation, onward sharing or particular technologies. The applicable licence and any required permissions must be respected.
Where a source is expressly available under the Open Government Licence v3.0, the required attribution must be retained. Where the publisher has not specified a different attribution, the standard statement is: "Contains public sector information licensed under the Open Government Licence v3.0." The licence is available at https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/. This statement applies only to information actually supplied under that licence, not to all platform content.
Some source materials, including particular NICE content, classification products or third-party datasets, are subject to separate terms. Where those terms restrict reproduction, territories, adaptation, attribution, promotional use or onward supply, they take priority over a general export permission. An Output must not be used to suggest that its original publisher endorses the Customer or its products.
Our subscription charges relate to access to the Service and its organisation, tools and analysis. They do not transfer ownership of source information. The Terms protect our software and original materials without removing rights that users independently hold in open-licensed data obtained lawfully. A disclaimer cannot remedy a missing licence or permission.
10. Aggregation, suppression and privacy
The Service is not intended to hold customer-uploaded patient-level records. Users must not attempt to identify people from aggregated information, reverse suppression, combine data to defeat privacy controls or submit identifiable patient information through support channels. Public-source personal data, if encountered, still requires lawful handling.
Unusual small counts, missing cells and suppression symbols should be interpreted using the source documentation. We do not promise that every publicly released dataset has no re-identification risk. Suspected privacy issues should be reported without circulating the affected information more widely.
11. Changes, withdrawals and corrections
We may revise datasets, mappings, assumptions, labels or methods to reflect source releases, correct errors, improve quality or comply with legal and licensing requirements. Outputs may change as a result. A previous version should not be assumed to remain suitable for a new decision.
Where we identify a material issue, we will assess its impact and take proportionate steps. These may include restricting affected content, adding a warning, correcting an Output or notifying affected customers where appropriate. We do not promise an individual response or correction within a fixed period unless specifically agreed, and some source errors must be referred to the publisher.
Material withdrawal of a subscribed feature remains subject to the contractual provisions on changes and remedies. Updating this notice does not retrospectively remove accrued rights or change an agreed liability cap.
12. Official status and liability
MedTech Compass is not owned, approved or endorsed by the NHS, government, NICE or another regulator merely because it references their material. Names and marks belong to their respective owners. Official guidance and policy remain those of the issuing organisation.
The contractual allocation of liability is in the SaaS Subscription Terms and the accepted Order. This notice does not create an additional liability cap, exclude our express reasonable-care-and-skill obligations or limit liability, individual rights or regulatory powers that cannot lawfully be excluded.
13. Reporting an issue
Contact mtcsupport@healthanalyticalsolutions.co.uk. Include the relevant module or report, the item concerned, the source and date where known, why you believe it is inaccurate, and the potential impact. A redacted screenshot or report reference is helpful. Do not include patient details, access credentials or unnecessary personal information.
