Entrustable training activity (ETA)
Evidence requirements
Evidence the activity has been undertaken by the trainee repeatedly, consistently, and effectively over time, in a range of situations. This may include occasions where the trainee has not successfully achieved the outcome of the activity themselves. For example, because it was not appropriate to undertake the task in the circumstances or the trainees recognised their own limitations and sought help or advice to ensure the activity reached an appropriate conclusion.
Reflection at multiple timepoints on the trainee learning journey for this activity.
Reflective practice guidance
The guidance below is provided to support reflection at different time points, providing you with questions to aid you to reflect for this training activity. They are provided for guidance and should not be considered as a mandatory checklist. Trainees should not be expected to provide answers to each of the guidance questions listed.
Before action
- What does success look like?
- Identify what is expected of you in relation to interpreting pH-impedance studies in patients with atypical symptoms and making appropriate recommendations.
- Consider how the learning outcomes apply, specifically in relation to analysing and interpreting data, producing reports, and making recommendations.
- Discuss with your training officer to gain clarity of what is expected of you in relation to assessing the correlation (or lack thereof) between atypical symptoms (e.g., respiratory, ENT symptoms) and objective pH-impedance findings.
- What is your prior experience of this activity?
- Think about what you already know about extra-oesophageal reflux and its potential manifestations, and which pH-impedance parameters are most relevant when evaluating atypical reflux.
- Consider possible challenges you might face during the activity, such as dealing with equivocal findings or situations where the pH-impedance results do not clearly correlate with the patient’s reported symptoms.
- Recognise the scope of your own practice for this activity i.e. know when you will need to seek advice or help, and from whom. You will need to seek advice from your Training Officer when required, for example when findings are equivocal or ambiguous, or require input from other investigations or clinics (e.g., ENT) in the patient pathway.
- Acknowledge how you feel about interpreting data that may not provide a clear answer to the patient’s clinical problem.
- What do you anticipate you will learn from the experience?
- Consider the specific skills you want to develop, such as formulating appropriate conclusions and recommendations for patients with atypical symptoms.
- Identify the specific insights you hope to gain into the challenges of interpreting pH-impedance data when symptoms are atypical and improving your ability to identify when findings are equivocal or require further investigation.
- What additional considerations do you need to make?
- Consult actions identified following previous experiences of reviewing clinical guidelines or literature specifically addressing the evaluation of atypical reflux symptoms.
- Identify important information you need to consider before embarking on the activity, such as reviewing knowledge regarding other investigations or clinics involved in the patient pathway for atypical symptoms.
In action
- Is anything unexpected occurring?
- Are you noticing anything surprising or different from what you anticipate whilst analysing and interpreting pH-impedance studies for atypical reflux symptoms?
- Are you encountering situations such as:
- The objective data shows minimal acid or non-acid reflux, yet the patient reports severe, frequent atypical symptoms (e.g., cough, globus), challenging the correlation assessment?
- The trace is complicated by frequent supragastric events or aerophagia, obscuring the ability to accurately assess proximal reflux associated with atypical symptoms?
- The calculated symptom association indices (e.g., Symptom Index or Symptom Association Probability) are equivocal, making a definitive conclusion on reflux causality difficult?
- How are you reacting to the unexpected development?
- How is this impacting your actions? For example, are you responding to the situation appropriately?
- Are you adapting or changing your approach to symptom correlation methodology or report phrasing for equivocal findings?
- Consider the steps you are taking in the moment, such as:
- Immediately reviewing the patient’s diary entries against the specific reflux events to ensure accurate timing and symptom association, focusing on non-acid reflux.
- Pausing the report drafting to consult published guidelines on the interpretation of equivocal symptom indices in atypical reflux presentations.
- How are you feeling in that moment? For instance, are you finding it difficult to confidently draw a conclusion when the objective data conflicts with the subjective symptoms? Is it affecting your confidence in making clear management recommendations?
- What is the conclusion or outcome?
- Identify how you are working within your scope of practice. For example, are you successfully documenting the objective absence of reflux while clearly stating the limitation of the test in the context of persistent atypical symptoms? Or are you needing support because the analysis suggests a rare extra-oesophageal disorder that requires input from an ENT or Respiratory specialist before final interpretation?
- What are you learning as a result of the unexpected development? For example, are you mastering a more rigorous approach to symptom association analysis in atypical reflux patients? Or gaining insight into the diagnostic limitations of pH-impedance monitoring in this patient group?
On action
- What happened?
- Begin by summarising the key steps you took when analysing and interpreting pH-impedance studies, specifically focusing on correlating objective findings with atypical reflux symptoms (e.g., cough, globus).
- Consider specific events, actions, or interactions which felt important, such as how you calculated symptom association indices or how you attempted to correlate sparse reflux events with severe reported symptoms.
- Include any ‘reflect-in-action’ moments where you had to adapt to the situation as it unfolded, for instance, immediately reviewing literature on extra-oesophageal reflux when the objective data showed minimal reflux but symptoms were severe, challenging the correlation assessment.
- How did you feel during this experience, e.g., did you feel focused on analysis or stressed by the challenge of correlating subjective symptoms with objective data?
- How has this experience contributed to your developing practice?
- Identify what learning you can take from this experience regarding data analysis.
- What strengths did you demonstrate, e.g., meticulous data analysis focusing on non-acid reflux events?
- What skills and/or knowledge gaps were evident, e.g., uncertainty regarding the challenges of interpreting equivocal symptom association indices?
- Compare this experience against previous engagement with similar activities – were any previously identified actions for development achieved?
- Has your practice improved in understanding the limitations of pH-impedance monitoring in patients with atypical symptoms?
- Identify any challenges you experienced, such as needing to seek advice or clarification on scope of practice regarding making management recommendations when objective findings are equivocal, and how you reacted to this.
- What will you take from the experience moving forward?
- Identify the actions you will now take to support the assimilation of what you have learnt, including from any feedback you have received, with regards to improving your ability to interpret and phrase conclusions for equivocal pH-impedance findings.
- What will you do differently next time you approach interpreting studies for atypical reflux symptoms, for instance, by proactively reviewing guidelines on the role of other investigations (e.g., ENT clinics, SeHCAT) in the atypical patient pathway?
- Do you need to practise any aspect of the activity further, such as formulating recommendations for patients where reflux is objectively absent but symptoms persist or key learning outcomes related to analysis and interpretation?
Beyond action
- Have you revisited the experiences?
- How have your subsequent experiences of presenting complex cases or attending ENT clinics since completing this specific training activity led you to revisit your initial approach or decisions during that activity? For example, discussion in an MDT about the difficulty correlating subjective respiratory symptoms with objective reflux data forced you to re-evaluate the rigour of your initial symptom association analysis during your first attempt at this training activity.
- Considering what you understand about extra-oesophageal reflux, non-acid reflux patterns, and symptom correlation indices now, were the actions or considerations you identified after your initial reflection on this training activity sufficient?
- How have you since implemented or adapted improvements in your analysis and interpretation methodology based on further learning and experiences? For example, how you proactively reviewed and integrated criteria for distinguishing between reflux and non-reflux related symptoms using pH-impedance data, demonstrating you have adapted improvements based on further learning.
- Has discussing equivocal symptom correlation or the diagnostic limitations of pH-impedance in atypical cases with colleagues, peers, or supervisors changed how you now view your initial experience in this training activity? For example, how professional storytelling with a senior colleague about a case with severe atypical symptoms but negative objective findings refined your understanding of the critical nature of accurately reporting the limitations of the test.
- How have these experiences impacted upon current practice?
- How has the learning from this initial training activity, in combination with subsequent interpretation experiences and MDT involvement, contributed to your overall confidence and competence in interpreting challenging data and communicating findings clearly, particularly in preparing for assessments like Case-Based Discussions (CBDs)? For example, how your accumulated ability in interpreting equivocal pH-impedance studies now enables you to confidently discuss the clinical significance of non-acid reflux events in a CBD assessment.
- How has reflecting back on this specific training activity, combined with everything you’ve learned since, shaped your current approach to critical interpretation?
- How does this evolved understanding help you identify when something is beyond your scope of practice or requires escalation? For example, how your evolved approach means you now routinely seek advice from the Training Officer or relevant specialist (e.g., ENT or Respiratory physician) immediately when objective findings fail to correlate with severe atypical symptoms, recognising that further specialist investigation may be required.
