International consensus on lung function testing during the COVID-19 pandemic and beyond.

Area of Science:

• Respiratory Physiology
• Infectious Disease Control

Background:

• COVID-19 transmission risk has disrupted essential respiratory diagnostic services globally.
• Resurgence of COVID-19 and new variants hinder the restoration of lung function testing.
• Ensuring safety for patients and staff during lung function tests is critical.

Purpose of the Study:

• To establish an international consensus on safe lung function testing protocols.
• To provide a roadmap for the restoration and continuity of services during and beyond the pandemic.
• To address safety concerns and enhance the lung function testing environment.

Main Methods:

• International expert consensus from 23 specialists in lung function and respiratory physiology.
• Literature review to support expert opinions.
• Development of a comprehensive roadmap for service delivery.

Main Results:

• Detailed strategies for patient journey management, including appointment preparation and environmental controls.
• Recommendations for testing room requirements, ventilation, physical distancing, and personal protective equipment.
• Guidance on specific tests, filters, special patient groups, and alternative testing locations.

Conclusions:

• The pandemic exposed vulnerabilities in lung function services, necessitating new mitigation strategies.
• This consensus provides actionable strategies to improve safety for lung function tests and testing environments.
• The proposed measures aim to protect services during current and future pandemics.
