Define your Question using PICO

P

Describe your patient, population or problem (age, sex, race, past medical history, etc.), the disease, or main topic of your question.

Patient/Population: Elderly adults aged 65 years and older who have chronic obstructive pulmonary disease (COPD), which makes them more vulnerable to respiratory infections and influenza-complicating issues.

I

What intervention or action are you considering - treatment, diagnostic test, etc. Is there a specific issue you’d like to investigate?

The goal of annual influenza vaccination is to decrease influenza-related morbidity and mortality in elderly patients with COPD.

Which research method (quantitative or qualitative) should be used to answer the study question?

Quantitative research is suitable to assess measurable outcomes like flu infection rates, hospitalization rates, and mortality.

If experimental, what research design should be used to compare the intervention group with the comparison (or control) group?

· randomized controlled trial

· cohort study

· case controlled studies

· case reports

· systematic reviews

· meta analysis

· editorials/expert opinions

Design: A randomized controlled trial (RCT) would be ideal but may not always be feasible; therefore, a cohort study tracking vaccinated versus unvaccinated COPD patients over one flu season is also appropriate. Alternatively, a systematic review of existing studies could summarize current evidence on the vaccine's efficacy in this specific population.

C

No influenza vaccination or use of other preventive measures (e.g., antiviral therapy, personal protective interventions, or usual COPD management without specific influenza vaccination).

O

What is the outcome you’d like to achieve? What are you trying to do for the patient? Relieve or eliminate the symptoms? Reduce the number of adverse events? Improve function or test scores?

Decrease in influenza-related events, reduction in hospitalizations due to respiratory causes, decreased COPD exacerbation, improved quality-of-life, and decrease in influenza-associated mortality.

State your Question resulting from PICO:

"In elderly adults aged 65 and older with COPD, how effective is the annual influenza vaccine compared to no vaccination or other preventive measures in reducing the incidence of flu-related complications and respiratory hospitalizations?"
