LG13: Scientific foundations of paediatric respiratory medicine

Epidemiology, pathophysiology, and clinical sciences

Advanced Trainees will have in-depth knowledge of the topics listed under each clinical sciences heading.

For the statistical and epidemiological concepts listed, trainees should be able to describe the underlying rationale, the indications for using one test or method over another, and the calculations required to generate descriptive statistics.

Investigations, procedures, and clinical assessment tools

Advanced Trainees will know the scientific foundation of each investigation and procedure, including relevant anatomy and physiology. They will be able to interpret the reported results of each investigation or procedure.

Advanced Trainees will know how to explain the investigation or procedure to patients, families, and carers, and be able to explain procedural risk and obtain informed consent where applicable.

Important specific issues

Advanced Trainees will identify important specialty-specific issues and the impact of these on diagnosis, management and outcomes.
