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 are some key enzyme and red cell membrane disorders (e.g., G6PD deficiency, hereditary spherocytosis), and what specific laboratory tests are used for their diagnosis?
- What principles underpin these diagnostic techniques, and what factors can affect their performance and interpretation?
- What are the typical laboratory findings in these disorders, and how do they correlate with the clinical presentation?
- Consider the specific insights you hope to gain, such as understanding the clinical significance of different enzyme and membrane disorders.
- Reflect on your current knowledge of these disorders and their laboratory diagnosis, and how this training activity will expand your expertise in this area.
- Consult with your training officer to identify the specific enzyme or red cell membrane disorder investigations you will be involved in during this training activity.
- Review the principles and procedures of the relevant assays, which may include enzyme activity assays or techniques like SDS-PAGE for membrane proteins.
- Think about potential challenges, such as understanding the technical complexities of these specialised tests or interpreting subtle abnormalities, and consider how you might address them (e.g., reviewing detailed protocols, seeking expert advice).
- Consider your current familiarity with these specialised investigations and identify areas where you need to focus your preparation.
In action
- When performing specific tests for enzyme or red cell membrane disorders (e.g., enzyme assays, osmotic fragility), what specific steps are crucial for the accuracy of these tests?
- What observations are you making during the testing process that might indicate issues or require adjustments?
- How confident are you in the reliability of your technical performance? What specific difficulties are you encountering with these specialised tests?
- What practical insights are you gaining into the investigation of these disorders?
- Are there other tests you should consider based on your initial findings or the clinical picture?
- Do you need to consult specialist protocols or colleagues? Are you following the established procedures for these investigations?
- During interpretation of the results, what abnormal values or patterns are you looking for that are indicative of an enzyme or membrane disorder?
- What specific disorders are you considering? What aspects of the interpretation are clear-cut, and what requires careful consideration of the limitations of the tests?
- How certain are you about your initial interpretation?
- What unexpected results have you obtained?
- What are you learning about the correlation between specific test results and different enzyme or membrane defects?
- How do these results fit with the known pathophysiology of these disorders? Are there alternative explanations for the findings?
- Should you discuss these results with a senior scientist or clinician?
- Are you interpreting the results according to relevant diagnostic criteria?
On action
- Identify the specific techniques you performed and interpreted for investigating an enzyme or red cell membrane disorder.
- What were the crucial steps involved?
- What were the expected results or control values for these techniques?
- What were the significant observations in the samples you analysed?
- Were there any technical challenges or unexpected findings during the investigation?
- How did you approach the interpretation of the results in the context of potential enzyme or red cell membrane disorders?
- What new skills or knowledge did you gain or improve related to the investigation of enzyme or red cell membrane disorders?
- Did you encounter any atypical results?
- What did you learn from exploring these?
- How did this activity enhance your understanding of the laboratory diagnosis of these specific types of disorders?
- What specific areas within the investigation of enzyme or red cell membrane disorders have you identified for further development?
- How will you apply the knowledge and skills gained from this activity to future investigations of similar disorders?
- What actions will you take to deepen your understanding and competence in this field?
- Are there any resources or support you believe would be valuable for your continued development in investigating these types of disorders?
Beyond action
- Reflect on your initial engagement with the specialised techniques used to investigate enzyme or red cell membrane disorders (e.g., enzyme assays, osmotic fragility testing). Has your understanding of the underlying pathophysiology and the interpretation of these specific tests evolved with further learning?
- Compare your experiences with this training activity to those from training activities focusing on other red cell disorders, such as haemoglobinopathies or acquired anaemias. What distinguishes the investigative approaches for these different categories of disorders?
- Review your original reflections on this training activity. Have any aspects of these rare disorders become clearer or have you identified new questions based on subsequent learning?
- Appreciate how understanding enzyme and red cell membrane disorders contributes to your comprehensive knowledge of haematological disorders. How has your learning from this training activity influenced your ability to recognise when these types of investigations might be appropriate, even if they are not routinely performed?
- Can you recall instances where your knowledge from this training activity has helped you understand the significance of referral testing or the limitations of routine blood tests in identifying these disorders?
- What transferable skills, such as critical appraisal of specialised test methodologies or understanding the importance of multidisciplinary collaboration in diagnosing rare conditions, did you develop through this training activity? How might these skills be valuable in your future career?
- Based on your reflection, what specific aspects of investigating enzyme or red cell membrane disorders would you like to learn more about in the future?
