Objectives:
This agreement is for the Surrey and Sussex Cancer Alliance to access Cancer Waiting Times (CWT) data. However, the Cancer Alliance is not a legal entity - its staff (and those accessing the Cancer Waiting Times data) are substantively employed by Royal Surrey NHS Foundation Trust . Royal Surrey NHS Foundation Trust is therefore the lead organisation, and the data controller who processes data. In this agreement, therefore, all references to accessing the data refer to the legal entity - Royal Surrey NHS Foundation Trust.
The Cancer Alliance staff, employed exclusively by the Lead Organisation are solely responsible for deciding the purposes and means of how the CWT data will be used to inform this work. While information may be gathered from the constituent organisations it has been assessed that this does not constitute influence which would require them to be classed as Joint Data Controllers.
Improvements for Cancer patients
The independent Cancer Taskforce set out an ambitious vision for improving services, care and outcomes for everyone with Cancer: fewer people getting Cancer, more people surviving Cancer, more people having a good experience of their treatment and care, whoever they are and wherever they live, and more people being supported to live as well as possible after treatment has finished.
Cancer Alliances
Cancer Alliances, which have been set up across England, are key to driving the change needed across the country to achieve the Taskforces vision. Bringing together local clinical and managerial leaders from providers and commissioners who represent the whole Cancer pathway, Cancer Alliances provide the opportunity for a different way of working to improve and transform Cancer services. Cancer Alliance partners will take a whole population, whole pathway approach to improving outcomes across their geographical footprints, building on their relevant Sustainability and Transformation Plans (STPs). They will bring together influential local decision-makers and be responsible for directing funding to transform services and care across whole pathways, reducing variation in the availability of good care and treatment for all people with Cancer, and delivering continuous improvement and reduction in inequality of experience. They will particularly focus on leading transformations at scale to improve survival, early diagnosis, patient experience and long-term quality of life. Successful delivery will be shown in improvements in ratings in the Clinical Commissioning Group (CCG) Improvement and Assessment Framework (IAF), including, importantly, in the 62 day wait from referral to first treatment standard.
https://www.england.nhs.uk/publication/ccg-iaf-methodology-manual/. Thus without access to the data as outlined in this request, the Surrey and Sussex Cancer Alliance will not be able to deliver work programme as outlined by the National Cancer Programme.
Cancer Wait Times (CWT) system
The Cancer Wait Times (CWT) system collects and validates the National Cancer Waiting Times Monitoring Data Set (NCWTMDS), allowing performance to be measured against operational Cancer standards. Data is validated and records merged to the same pathway to cover the period from referral to first definitive treatment for Cancer and any additional subsequent treatments.
The CWT system then determines whether the operational standard(s) that apply were met or not for the patient and the accountable provider(s). The CWT system holds NCWTMDS in a series of pre-aggregated static reports. These reports are available monthly and quarterly data (aligned with the National Statistics for Cancer Waiting Times published by NHS England). Users can query the CWT system to generate reports to feedback on the progress towards meeting these targets.
Surrey & Sussex Cancer Alliance
Royal Surrey NHS Foundation Trust will directly access the Cancer Waiting Times System on behalf of Surrey & Sussex Cancer Alliance across the South East. Surrey & Sussex Cancer Alliance is hosted by Royal Surrey NHS Foundation Trust and covers a population of 3.2 million people.

Data access
The CWT system provides one organisation (the lead organisation - Royal Surrey NHS Foundation Trust) representing each Cancer Alliance, with access to the following;
a) Aggregate reports (which may include unsuppressed small numbers)
b) Pseudonymised record level data - users can directly download this data from the CWT system
c) I-View Plus tool
Lead organisations (in this case Royal Surrey NHS Foundation Trust) will only access patient records which fall within the Cancer Alliances' footprint of responsibility based on the patients' CCG of responsibility. This Cancer Alliance is limited to South-East Cancer Patients.
Some of the CCGs who fall within the boundary of the Cancer Alliance may have access to CWT data (covering their commissioning area) as part of their Data Sharing Agreements (DSA) which cover Commissioning purposes. As this DSA is for a much wider geographical area and the CCGs in question do not influence how the data will be used (i.e they are not Data Controllers) this is not considered to be excessive processing).
A) Aggregate reports including small numbers
Aggregate data is available in the form of reports at Provider (Trust) and CCG level.
Small numbers may be included in the aggregate data reports and are essential for analyses carried out by lead organisations (in this case Royal Surrey NHS Foundation Trust).
Investigating breaches
Lead organisations (in this case Royal Surrey NHS Foundation Trust) routinely monitor performance and standards using the CWT system, particularly in relation to breaches of the 62 day wait target. Due to the large number of potential Trust/CCG combinations, breach counts could result in small numbers as in some cases there are less than 6 breaches in a whole year. Given that financial penalties are linked to target breaches counts must accurately reflect the true percentage without suppression.
Mitigating risk of re-identification
Risk of disclosure is minimised as the dataset does not include patient demographics (increasing risk of re-identification) that may allow users to identify an individual e.g. there are no age, ethnic categories or geographic breakdowns.
Additionally, the aggregation categories are such that the data is not at a lesser granular level e.g. the source NCWTMDS data collects information at ICD diagnosis code level, but the CWT system aggregates at tumour group level e.g. Head & Neck, Upper Gastrointestinal, lower Gastrointestinal, Breast etc.
B) Pseudonymised record level extracts
Lead organisations will access record level pseudonymised data which includes the system generated pseudo CWT patient ID.
Any record level data extracted from the system will not be processed outside of the authorised users of the system.
C) i-View Plus .
iView Plus uses cube functionality to allow lead organisations to produce graphs, charts and tabulations from the data through the construction of queries. The data in iView plus is split by operational standard being measured and can then be analysed against a range of dimensions collected in the data and measures such as count, percentage and median. The outputs of iView Plus are aggregate, and no record level data can be obtained, however some queries may result in small numbers and these currently have limited disclosure control applied, see A) for further explanation.
iView Plus holds published data, the lowest organisational granularity is trust level, data can also be aggregated to CCG level and other health hierarchies.
Lead organisations will use the data to both monitor and improve performance against the Cancer Waiting Time standards and to inform wider Cancer pathway improvements.
Lead organisations use of the data will fall into two separate categories, each requiring different levels of suppression, and onward sharing both within the Cancer Alliance and with wider NHS stakeholders;
Purpose One - Aggregate local reports
Generation of routine Cancer Waiting Times reports at Provider (Trust) or CCG level. Lead organisations will access a summary of the totals for the Providers (Trust) and CCG's that are treating cancer patients where they have a commissioning responsibility for that patient (based on the CCG they are aligned to). This analysis would then be shared with the providers and commissioners and used to inform service improvement by providing benchmarked comparable data. The format of this report would be in a tabulated or graphical form (i.e. not record level) but may contain small numbers. An example of where small numbers would not be suppressed would be in relation to cases of breaches against a standard where small numbers would be essential to ensure the report is meaningful.
Examples of this type of analysis include:
a. Comparative Cancer Waiting Times performance at tumour group and individual tumour site (i.e. ICD10 code) level for Trusts and CCGs across the geography
b. Analysis of Cancer Waiting Times performance by treatment modality
c. Grouping length of waits for standards
d. Analysis of derived breach reason fields to identify trends in reasons for delays
e. To provide assurance through comparative analysis (e.g. orphan record identification, active monitoring proportions and validation of waiting list adjustments entered)
f. Analysis of flows of patients including analysis by provider trust site
g. Reviewing waits between surgery and radiotherapy for Head and Neck Cancer patients with a maximum recommended wait of 6 weeks
h. Reviewing routes to diagnosis of patients
i. Quantifying treatment volumes by provider organisation including analysis treatment rates
Purpose Two - Sharing of record level data with providers and commissioners responsible for direct patient care for that patient. This will be for local audit purposes.
The two broad purposes for this would be;
1) To support audit work
2) Investigate individual outliers to the national standards
Pathway analysis will be undertaken, identifying trends in reasons for breaches. The analysis will inform system wide pathway improvements and compliance to the national standards. Examples of potential changes to achieve this could be to support trusts in additional resources and processes and also to facilitate discuss between trusts for example in reaching agreement for diagnostics between trusts.
Examples of the types of reasons for this include;
a. Patients waiting excessively long period of time to seen of received treatment
b. Identifying areas of concern which require more detail or clarification from provider
c. Identification of 28 day standard exceptions - National guidance states patients who are diagnosed with cancer should be informed face to face, this would highlights numbers of patients who are not told in person by provider
d. Audits to review orphan records which require local providers to review local patients records
Record level data (pseudonymised) will be shared via NHS.net email accounts and access will be controlled by password protecting all files.
Yielded Benefits:
CWT data allows the alliance to assess performance and benchmark, identifying outliers and policy developments required. The data highlights areas where there is inequity of access or care of patients in the region, and continued monitoring and long term trends can evidence improvement work. Comparison of volume and performance by CCG, trust and tumour type in the SSCA region have provided insight into which areas or tumour types are under increased strain, and therefore are not working as an optimal pathway, and which are assured and confident, and can be explored for areas of good practice. The Cancer Alliance produces a monthly data pack that summarises all pathway standards into an easy to digest format with distribution to key stakeholders. This pack highlights performance and initiates improvement work locally, with identification of outliers which have resulted in performance improvement and improved patient care and experience.
Expected Benefits:
1) Benefits type: Supporting delivery of CWT standards
The Cancer Waiting Times standards are key operational standards for the NHS, which aim to reduce the waits for diagnosis and treatment for Cancer patients, which will support improvements to survival rates and improve patient experience. This includes the new 28 day faster diagnosis standard being introduced as a standard from April 2021.
A key enabler to achieve these standards, and thus improve survival and patient experience is the role of Cancer Alliances locally to work with providers and commissioners to improve patient pathways. Access to the Cancer Waiting Times data as detailed in the above will enable Cancer Alliances to have informed discussions and allocate resources optimally to improve performance against these standards. It will also enable Cancer Alliances to work with local providers and commissioners to identify outliers against the standards, and mitigate the risk of similar delays for other patients.
Improvement would be expected on an on-going basis with standards already in place for nine standards:-
2 week wait urgent GP referral 93%
2 week wait breast symptomatic 93%
31 day 1st treatment - 96%
31 day subsequent surgery 94%
31 day subsequent drugs 98%
31 day subsequent radiotherapy 94%
62 day (GP) referral to 1st treatment 85%
62 day (screening ) referral to 1st treatment 90%
62 day upgrade to 1st treatment locally agreed standard
In addition this access and use of data will be key in delivering the new 28 day faster diagnosis standard being formally performance managed from April 2021, with a threshold of at least 75%
2) Benefits type: Improvements beyond constitutional standards
This access and resulting analysis will enable Cancer Alliances to undertake local analysis beyond the Cancer Waiting times operational standards to support improvements to Cancer patients pathways beyond those already achieved by improving performance against standard set. This could include reviewing times between treatments, or treatment rates.
The overall aim of this type of additional analysis would be to support improvements to Cancer patients survival and experience. The NHS England and NHS Improvement Long Term Plan sets out a number of ambitions to be met nationally and locally, that from 2028, an extra 55,000 people in England each year, will survive for five years or more following their cancer diagnosis and that three in four cancers (75%) will be diagnosed at an early stage. For both of these, improvements to the diagnostic and treatment pathways are key, and require Cancer Alliances to be able to analyse the Cancer Waiting Times dataset to identify sub-optimum pathways and resulting improvements.
2) Benefits type: Improvements beyond constitutional standards
This access and resulting analysis will enable Cancer Alliances to undertake local analysis beyond the Cancer Waiting times operational standards to support improvements to Cancer patients pathways beyond those already achieved by improving performance against standard set. This could include reviewing times between treatments, or treatment rates.
The overall aim of this type of additional analysis would be to support improvements to Cancer patients survival and experience. The Cancer Taskforce recommendation set out a number of ambitions to be met nationally and locally by 2020 including improving 1 year survival for Cancer to 75%, and improving the proportions of patients staged 1 or 2 to 62%. For both of these improvements to the diagnostic and treatment pathways are key, and require Cancer Alliances to be able to analyse the Cancer Waiting Times dataset to identify sub-optimum pathways and resulting improvements.
Outputs:
Outputs fall into the following categories:
1) Analysis to support delivery of Cancer Waiting Times standard and identify variation, including clinical discussions to improve patient pathways
a. Comparative Cancer Waiting Times performance at tumour group and individual tumour site (i.e. ICD10 code) level for Trusts and CCGs.
b. Analysis of Cancer Waiting Times performance by treatment modality to inform discussions
c. Grouping length of waits for standards to inform discussions on going beyond constitutional standards
d. Analysis of derived breach reason fields to identify trends in reasons for delays.
e. To provide assurance through comparative analysis (e.g. orphan record identification, active monitoring proportions and validation of waiting list adjustments entered)
f. Analysis of flows of patients including analysis by provider trust site
g. Outlier identification including exceptionally long waits to inform individual queries to providers
2) Cancer Waits analysis (not directly linked to constitutional standards) for the aim of identifying variation which may impact Cancer patients outcomes or patient experience. Examples for use of the data may include reviewing waits between surgery and radiotherapy for Head and Neck cancer patients with a maximum recommended wait of 6 weeks and using the data source to validate surgical numbers by provider trust.
The overarching aim of all future analysis/outputs is to inform priorities and potential investment to improve Cancer pathways including reducing Cancer incidence and mortality, improving Cancer survival, improving patient experience, improving service efficiency and meeting national constitution standards relating to Cancer patients.
Processing:
Access to the Cancer Wait Times (CWT) System will enable Cancer Alliances to undertake a wide range of locally-determined and locally-specific analyses to support the Cancer Taskforce vision for improving services, care and outcomes for everyone with Cancer.
Only the lead organisation (Royal Surrey NHS Foundation Trust) will directly access the Cancer Waiting Times system. Extracts can be downloaded and will be stored on the Royal Surrey NHS Foundation Trust servers. Role Based Access Control prevents access to data downloads to employees outside of the analytical team responsible for producing outputs; the Surrey & Sussex Cancer Alliance.
The CWT system is hosted by NHS Digital, access to and usage of the system is fully auditable. Users must comply with the use of the data as specified in this agreement. The CWT system complies with the requirements of NHS Digital Code of Practice on Confidential Information, the Caldicott Principles and other relevant statutory requirements and guidance to protect confidentiality.
Access to the CWT system will be granted to individual users only when a valid Data Usage Certificate (DUC) form is submitted to NHS Digital via the lead organisations Senior Information Risk Officer (SIRO), and where there is a valid Data Sharing Agreement between the lead organisation and NHS Digital.
Approved users will log into the system via an N3 connection and will use a Single Sign-On (users are prompted to create a unique username and password).
Royal Surrey NHS Foundation Trust users will access:
a) Aggregate reports (which may include unsuppressed small numbers)
b) Pseudonymised record level data - users can directly download this data from the CWT system
c) I-View Plus tool (aggregated - access to produce graphs, charts/tabulations from the data through the construction of queries). This will give users access to run bespoke analysis on pre-defined measures and dimensions. It delivers the same data that is available through the reports and record level downloads (i.e. it will not contain patient identifiable data).
Any record level data extracted from the system will not be processed outside of the Royal Surrey NHS Foundation Trust unless otherwise specified in this agreement. Following completion of the analysis the record level data will be securely destroyed.
Users are not permitted to upload data into the system.
Data will only be available for the Providers (Trust) and CCGs that are treating cancer patients where they have a commissioning responsibility for that patient (based on the CCG that this Cancer Alliance is aligned to).
The data will only be shared with other members of the Cancer Alliance in the format described in purpose 1 and purpose 2 of this agreement. The primary method for sharing outputs will be storing data/reports on internal storage spaces which only members of the team can access. Aggregate data/ graphical outputs may be shared via e-mail; for example as part of Alliance meeting papers.
Where record level data is shared with individual trusts these are shared only with trust(s) who were involved in the direct care of the patient, only via NHS.net email accounts.
As part of partnership working to improve Cancer Waiting Times performance, outputs may be shared with national/ regional bodies including the National Cancer Registration and Analysis Service. Sharing of the data may be done via the Open Exeter system. Data will only be shared as described in purpose one and purpose two of this agreement and where recipient organisations hold a valid Data Sharing Agreement with NHS Digital to access Cancer Waiting Times data.
Training on the CWT system is not required as it is a data delivery system and it does not provide functionality to conduct bespoke detailed analysis. User guides are available for further assistance.
Access to the CWT system data is restricted to Cancer Alliance employees who are substantively employed by the Data Controller in fulfilment of their public health function.
The Cancer Alliances will use the data to produce a range of quantitative measures (counts, crude and standardised rates and ratios) that will form the basis for a range of statistical analyses of the fields contained in the supplied data.
Typical uses will include:
1) Analysis to support delivery of Cancer Waiting Times standard and identify variation, including clinical discussions to improve patient pathways
a. Comparative Cancer Waiting Times performance at tumour group and individual tumour site (i.e. ICD10 code) level for Trusts and CCGs.
b. Analysis of Cancer Waiting Times performance by treatment modality to inform discussions
c. Grouping length of waits for standards to inform discussions on going beyond constitutional standards
d. Analysis of derived breach reason fields to identify trends in reasons for delays.
e. To provide assurance through comparative analysis (e.g. orphan record identification, active monitoring proportions and validation of waiting list adjustments entered)
f. Analysis of flows of patients including analysis by provider trust site
g. Outlier identification including exceptionally long waits to inform individual queries to providers
2) Cancer Waits analysis (not directly linked to constitutional standards) for the aim of identifying variation which may impact Cancer patients outcomes or patient experience. Examples for use of the data may include reviewing waits between surgery and radiotherapy for Head and Neck cancer patients with a maximum recommended wait of 6 weeks and using the data source to validate surgical numbers by provider trust.
