COPD trial enrollment through pulmonologist referrals

Short answerPulmonologists are the core referral source for COPD trials because their patients usually have spirometry confirmed diagnoses. Primary care is a large but less reliable source: one Canadian study found only a third of at risk primary care patients with COPD knew their diagnosis, and a Texas review found only 29% of patients diagnosed with COPD had spirometry on record.

Why does diagnosis quality matter for COPD trials?

COPD trials require a spirometry confirmed diagnosis, and many primary care diagnoses are not confirmed. In a Canadian study of at risk primary care patients, 20.7% met spirometric criteria for COPD, but only 32.7% of them knew their diagnosis beforehand (CMAJ). A review of primary care clinics in Texas found only 29% of patients diagnosed with COPD had spirometry, and some diagnosed patients did not meet the criteria when tested (MDedge).

Which physicians should a COPD site contact?

Pulmonologists, whose patients typically have spirometry and exacerbation history on file.
Primary care physicians, for volume, with clear guidance on which patients to send.
Allergists, for studies that include asthma or overlap populations.

How do you get better referrals from primary care?

Tell physicians exactly what the site will verify. If your protocol requires post bronchodilator spirometry, say the site can perform it, so a physician can refer a likely patient without a confirmed test. That turns underdiagnosis from a barrier into a reason to refer.

Why does respiratory enrollment speed matter?

Tufts CSDD found respiratory trials among those with the highest relative daily direct costs (PubMed), so sponsors watch respiratory site performance closely.

What should a COPD outreach plan include?

The core specialists and relevant primary care physicians within realistic driving distance of the site.
A one page summary with the diagnosis requirements, key exclusions, procedures, and visit schedule.
A named coordinator contact, and a commitment to report back on every referral.
Follow up by email and LinkedIn, prioritizing physicians who engaged.
