WPBA: Case-Based Discussion (CbD)

The CbD is a structured oral interview designed to assess your professional judgment while reflecting on a clinical case. The assessment looks at performance against the Capabilities and reviews how holistic, balanced and justifiable decisions were made in relation to patient care. It assesses understanding and application of medical knowledge, ethical frameworks, ability to prioritise and how the complexity and uncertainty of the consultation were recognised and approached.

The requirements

  • In ST1, a minimum of 4 CbDs must be completed (a minimum of two for each 6 monthly Educational Supervisor Report (ESR)
  • In ST2, a minimum of 4 CbDs must be completed (a minimum of two for each 6 monthly Educational Supervisor Report (ESR)
  • In ST3 a minimum of 5 CATs must be completed (which can include CbDs)

It is expected that 2 or 3, but can be up to a maximum of 4 Capabilities and 2 Clinical Experience Groups be linked to each CbD by the registrar when preparing the case so that in-depth reflection and meaningful feedback is given for each. Separate assessments can be used if the assessment covers a larger number of either.

Ideally, by the end of training, the CbDs completed will cover the full range of the Capabilities providing triangulation of grades for each Capability across a range of different assessment methods. It is expected that all Capabilities will have been assessed using a formal assessment tool at least once in the three-year training period, but not all need to be done within a CbD.

While it is not mandatory to have a CbD for each Clinical Experience Group, a range of types of assessment and information will need to be provided in the Portfolio. This is to show exposure to, learning from, and competence in caring for, the range of Clinical Experience Groups across each training year. All Clinical Experience Groups should be covered by the range of assessments completed.

Before the assessment

The case should be one that has been managed independently by a GP registrar, (it is not appropriate to have received advice from another doctor for the consultation and then to be assessed on actions taken by that other doctor).

Before the assessment, the trainee should map the case to up to three Capability areas as these areas will be discussed during the assessment and it is these Capabilities the assessor will grade (an additional capability can be mapped later by the trainer if needed). The Capabilities should not necessarily be those that were covered well, as more useful learning can be achieved by choosing areas that were challenging.

The discussion and assessment

Protected time is needed for the assessment and the clinical entry should be shared with the supervisor before the assessment so they can familiarise themselves with the case. How long a CbD takes will depend on the complexity of the case, but the discussion (including assessor feedback) usually takes between 20-30 minutes.

Within primary care placements in ST1/2, assessors will be approved GP Clinical/Educational Supervisors who have met the GMC standards. CbDs can be carried out in secondary care by Clinical Supervisors (the named Clinical Supervisor should complete at least one CbD during each rotation), by doctors who are ST4 or above, or Specialist and Associate Specialist (SAS) doctors with equivalent experience who have met the GMC assessor requirements.

During the discussion, if the assessor feels any other Capabilities have been covered, these can be added to the assessment form. While the assessment is about what was done, for some more difficult capabilities it may be necessary to add hypothetical challenge to assess knowledge, for example regarding ethics or fitness to practice.

Recording the assessment on the Portfolio

The assessor will then complete the assessment form within the Portfolio. Each of the discussed Capability areas will be graded. The assessor will document their feedback on performance and their justification for their grades as well as their recommendations for further development.

Most assessors will have full access to the Portfolio but in non-primary care settings they may need a ticket code to enable the assessment form to be completed.

To use the ticketed feedback system, click on ‘generate a new ticket’ within the Portfolio, select the ‘CbD assessment form’ and complete the assessor’s details. An email will then be sent providing a login code for the assessor to use to complete the ticketed CbD assessment form.

Example Case-based Discussion (CbD) questions

The following resource contains example questions against each Curriculum capability that can be asked as part of a Case-based Discussion. The questions should generate information related to each capability. These questions are suggestions and examples only - trainers and supervisors do not have to ask every question in each category.

Graded/Rating of GP Registrars

  • When in primary care, GP registrars are rated against the expected standard required at the end of training.
  • When in non-primary care, GP registrars are rated in comparison to other GP registrars at the same stage of training or comparable specialty registrars in the speciality/setting they are working in.

Example questions for supervisor/assessor to ask for each capability

  • Was there any point in the consultation where you felt out of your depth?  How did you define your limits? What did you then do?
