Episode 26: COPD: Confusing Overwhelming Puffer Data leaving us Breathless

In episode 26, we examine the initial management of COPD. We first discuss the diagnosis of COPD and if screening is recommended. We encourage an initial focus on smoking cessation and then episodic, symptom control. We then review long acting puffers and the large body of confusing research with underwhelming and at times conflicting results. Unfortunately, the data available for long acting puffers serves as a good example of how more information can exacerbate confusion.
