Beginner-Friendly Pulmonology Research Ideas and Methods

Pulmonology offers accessible research for beginners because many questions can be answered with routinely collected data, spirometry or imaging results, or with literature reviews. The key is to define a narrow question, outcome and population and to work with a supervisor.

Idea types

• Epidemiology: prevalence of chronic obstructive pulmonary disease, asthma or sleep apnoea in a clinic population.
• Prognosis: factors associated with exacerbations, hospital stay or readmission.
• Diagnosis: accuracy of a questionnaire, a point-of-care ultrasound sign or a biomarker for pneumonia or pleural disease.
• Care processes: adherence to inhaler technique education, vaccination status, time to antibiotics.
• Environmental and occupational health: exposure and respiratory outcomes (with careful confounding control).
• Evidence synthesis: reviews of rehabilitation, digital self-management or screening.
• Case reports: rare presentations or drug-related lung disease.

Methods and measures

• Lung function (for example FEV1/FVC) measured by standard protocols; define the equipment, reference equations and quality criteria.
• Symptom scores and quality-of-life questionnaires; use validated versions in the right language.
• Imaging and laboratory tests with defined thresholds.
• Outcomes: exacerbation, hospital admission, mortality, with clear time windows.

Illustrative example

Invented for teaching. "In adults with COPD attending a clinic in 2023, is inhaler technique error (observed by a nurse) associated with moderate or severe exacerbations in the following 12 months?" Design: retrospective cohort using clinic records. Limitations: confounding by severity, misclassification, single centre.

Cautions

Exposure data (such as smoking history) are often incompletely recorded. Define how missing data will be handled and avoid causal language.

Common pitfalls

• Using spirometry values without checking test quality.
• Combining different disease definitions without justification.

Key takeaways

• Choose a narrow question with clear definitions.
• Use validated measures and plan for missing data.
