C2-Ai CRAB Clinical Informatics

C2-Ai Patient Tracking List

C2-Ai PTL risk stratification supports the improvement of the hospitals management of patient treatment list (PTL) using an Intelligent System AI that will provide predicative and operational decision support for clinicians and managers. The implementation of C2-Ai’s PTL risk stratification tool be for elective patients waiting for surgery or procedure.

  • Standardise approach for prioritisation and validation of elective PTL
  • Support clinical equitability (including social determinants of health)
  • Reduce administration time by reducing manual processes, rework and cancellations
  • Reduce average RTT waiting time through effective prioritisation
  • Strategic capacity planning based on paients greatest need and risk
  • Reduce potential complaints or litigation from patients due to delays
  • Risk adjusted surgical deaths and complications at specialty level


  • PTL – quality assurance system, Lower patient harm and mortality
  • ~ 125 bed-days saved per 1,000 patients
  • Up to 8% reduction in emergency admissions from PTL
  • More detailed view of clinical risk for each patient
  • Optimisation of sites to and routing across trusts/regions
  • Support to identify which patient to optimise prior to operation

End-of-contract data extraction
C2-Ai decommission the databases and provide data destruction certificate.
End-of-contract process
C2-Ai decommission the databases and provide data destruction certificate if deemed appropriate.
The offboarding plan for this Call-Off Contract is:
Destruction of data on live systems
For analysis, data is kept on controlled live systems for a period defined in the data processing agreement. Once it is deemed that data should be removed from live systems, the data is deleted using standard file deletion policies. This prevents its continued use in the organisation. Following deletion, a certificate is issued and stored in the supplier-side asset register.
System decommissioning
When a system is decommissioned, either due to the end of a job or because the server or drive is being depreciated, then the drives will all be cleared using a routine such as Kill Disc. The routine will be run for the recommended number of times to provide reasonable confidence that all data have been removed and cannot be re-accessed. A certificate will be issued and stored in the supplier-side asset register. If a data drive is not to be reused, it will then also be destroyed physically before disposal, and a photograph of the drive stored with the media destruction certificate in the supplier-side asset register.

Covid-19 recovery

Covid-19 recovery

C2-Ai supports hospital and ICS organisations and businesses to manage and recover from the impacts of COVID-19,through fast clearing of elective surgical waiting list. Putting the right patient, in the right place, at the right time.
C2-Ai’s efficient, evidence-based risk stratified triage of the surgical waiting lists for individual patients.
Delivering effective/ objective prioritisation and validation of the waiting lists.
Uniquely takes into account waiting list deterioration to prevent avoidable harm and unnecessary emergency admissions.
System integrates into existing pathway management tools and can triage hundreds of thousands of patients on the waiting list dynamically at scale.
Results provide rapid indication as to whether the patient is at high risk or low risk of deterioration if delays in treatment.
Identifies individualised mortality and post-operative complications risks
Fast clearing of the elective waiting list backlog with improved clinical prioritisation of patients (27% reduction in patients waiting >52 weeks).
Site specific patent mobilisation, capacity and workforce planning.
Pre-habilitation – support optimisation of pathways of care.
Avoidable Harm: Reduced emergency admissions and post op complications (approximately 6-8% at risk of an emergency admission from delayed care, one trust increased physiotherapy resource to mitigate post op chest infection risk).
Reducing deterioration of patients which would result in increasing LOS and cost (5k patients found to have increased risk of complication over 6-month period. 2.5k x 1day increased LOS = 2.5k saved bed days)
Reduction in health inequalities – tracking clinical outcomes by SDoH
Financial savings: reduced administration burden to allow clinicians to undertake more clinical duties (417 sessions saved so far ~£200k at one Trust).
System is easy to implement and is available to all NHS Trusts and ICSs
