Assessments

Complete 4 Case-Based Discussions

Complete 4 DOPS or OCEs

Direct Observation of Practical Skills Titles

  • Perform an image registration for the purpose of adaptive planning, evaluating the outcome for its potential clinical use.
  • Perform measurements as part of clinical trial dosimetry and/or planning audit.
  • Calculate patient dose from a kV imaging system to be able to assess the associated dose given to patients.
  • Calculate biological effective doses for different fractionation regimes for tumours and organs at risk, including compensation strategy for gaps in treatment.
  • Calculate the dose given to a patient after a radiotherapy error and make recommendations based on the findings.

Observed Clinical Event Title

  • Communicate results of an audit to a multidisciplinary team.
  • Discuss the outcome of radiobiological calculation for a patient re-treatment with a healthcare professional, appropriately communicating the risks.
  • Present a new technique or clinical trial and discuss the impact on the department and patient care.
  • Summarise a case discussed at a multidisciplinary team meeting and discuss the treatment options and rationale in the context of the patient’s history with another healthcare professional.

Learning outcomes

# Learning outcome
1

Perform required measurements to establish whether a treatment machine is suitable for clinical use and apply corrective actions where required.

2

Perform dosimetric and radiobiological calculations.

3

Generate, adapt and evaluate treatment plans using complex techniques.

4

Critically appraise the application of radiotherapy treatments and techniques and make recommendations considering safety, efficacy, outcomes and the suitability and impact on the patient.

5

Evaluate the application of novel and evolving techniques and treatments in radiotherapy.

6

Plan for adoption and validation of new techniques and equipment in radiotherapy.

7

Assess the quality of practice and make recommendations for improvements.

8

Practice effectively as part of a multidisciplinary team to provide safe, patient centred radiotherapy treatments.

Clinical experiences

Important information

Clinical experiences help you to develop insight into your practice and greater understanding of your specialty. Clinical experiences should be included in your training plan and you may be asked to help organise your experiences. While Clinical Experiences are not assessed, reflections and observations from your experiences can be used to support evidence for competencies to demonstrate your awareness and appreciation of your specialty and it’s impact on patient care. You may find it helpful to capture thoughts from your experiences in your reflective log.

Activities

  1. Observe a 4D CT scan and observe the treatment being delivered to appreciate the role in the patient pathway.
  2. Observe a discussion with a patient about radiotherapy consent or giving consent for entry into a clinical trial.
  3. Attend a meeting where quality and departmental radiation incidents are discussed.
  4. Attend a multidisciplinary meeting where a new technique is introduced or a new clinical site is being proposed and/or being discussed.

Academic content (MSc in Clinical Science)

Important information

The academic parts of this module will be detailed and communicated to you by your university. Please contact them if you have questions regarding this module and its assessments. The module titles in your MSc may not be exactly identical to the work-based modules shown in the e-portfolio. Your modules will be aligned, however, to ensure that your academic and work-based learning are complimentary.
