Rehabilitation Complexity Scale – Extended (RCS-E v13)

The Rehabilitation Complexity Scale - Extended (RCS-E v13) provides a simple overall measure of resource requirements for rehabilitation, including: 

  • Basic care / risk
  • Rehabilitation nursing
  • Therapy (number of disciplines and intensity)
  • Medical acuity
  • Equipment needs

The RCS-E is an easy, quick to complete, measure that can be applied serially to measure complexity (or resource requirements) as these change over time in a rehabilitation setting. 

  • It is a good indicator of the cost of rehabilitation, predicting about 70% of the variable costs within a specialist inpatient rehabilitation setting.

RCS-E provides a good indication of caseload and forms part of the mandated toolset within the UK Rehabilitation outcome Collaborative (UK ROC) national clinical database for specialist rehabilitation and has been used to demonstrate variation in complexity of rehabilitation need and for developing the mechanism for use within the weighted bed day tariff. 


  • The RCS-E forms part of the mandated toolset within the UK Rehabilitation Outcomes Collaborative (UK ROC) national clinical registry for specialist rehabilitation since 2012
  • Within the dataset, it is applied as an indicator of overall caseload complexity
  • Within the NHSE national tariff for inpatient specialist rehabilitation it is applied in 5 bands to produce a complexity-weighted bed day cost (see source reference in “development” section).


The UK ROC software that contains collates RCS-E alongside the other UK ROC measures of need, input and outcome is built built in Microsoft Excel and is freely available from the UK ROC team: Contact
