Telepulmonology and telespirometry

Area of Science:

• Pulmonology
• Digital Health
• Primary Care Medicine

Background:

• Spirometry interpretation and quality are challenging in primary care, potentially leading to misdiagnosis of pulmonary diseases like COPD.
• Telespirometry and telepulmonology consultation (TPC) offer solutions for monitoring spirometry quality and supporting general practitioners (GPs).

Purpose of the Study:

• To evaluate the impact of telespirometry and TPC on spirometry test quality, diagnostic agreement, and referral rates.
• To assess the educational benefits of TPC for GPs in interpreting pulmonary function tests.

Main Methods:

• Telespirometry involved pulmonologists assessing uploaded spirometry results for quality and diagnostic findings.
• TPC allowed GPs to digitally consult pulmonologists for advice or to prevent referrals.
• Data collected included spirometry quality, interobserver agreement (Kappa), referral prevention rates, and GP perceived educational effects.

Main Results:

• Nearly one-third of telespirometry tests were of moderate or poor quality.
• Interobserver agreement on diagnostic findings between GPs and pulmonologists was fair (Kappa = 0.38).
• Telepulmonology reduced physical referrals by 22%, with 69% of TPCs sought for advice.

Conclusions:

• Telespirometry and TPC can enhance spirometry quality and interpretation in primary care settings.
• Telepulmonology significantly reduces the need for physical referrals to pulmonologists.
• GPs reported substantial learning benefits from telepulmonology consultations, with 90% indicating educational gains.
