Microbiological contamination in home continuous positive airway pressure (CPAP) devices. Study protocol

Area of Science:

• Respiratory Medicine
• Infectious Diseases
• Microbiology

Background:

• Home mechanical ventilation, particularly continuous positive airway pressure (CPAP), is vital for conditions like obstructive sleep apnea and its usage is increasing.
• A potential link between inadequate CPAP equipment hygiene and respiratory infections is suspected, though not fully understood.
• Healthcare-associated infections are a significant concern, with a known 30% being preventable.

Purpose of the Study:

• To quantify the levels of bacterial and fungal contamination in commonly used home CPAP devices.
• To identify critical points of contamination within CPAP equipment.
• To gather data for improving prevention strategies, patient education, and nursing care related to home respiratory therapy.

Main Methods:

• A prospective, cross-sectional study involving 25 patients on home CPAP therapy for at least six months.
• Microbiological sampling from key CPAP device components: housing, tubing, filter, interface, and humidifier.
• Analysis conducted at a certified microbiology department, alongside collection of clinical and patient health data.

Main Results:

• This section is to be filled once the study results are available.

Conclusions:

• This research will provide crucial data on CPAP device contamination.
• Findings are expected to inform enhanced hygiene protocols and patient education to mitigate infection risks.
• The study aims to contribute to reducing the incidence of respiratory infections associated with home mechanical ventilation.
