Use of infection control measures in people with chronic lung disease: mixed methods study.

ABSTRACT

Background: The introduction of community infection control measures during the COVID-19 pandemic was associated with a reduction in acute exacerbations of lung disease. We aimed to understand the acceptability of continued use of infection control measures among people with chronic lung disease and to understand the barriers and facilitators of use. Methods: Australian adults with chronic lung disease were invited to an online survey (last quarter of 2021) to specify infection control measures they would continue themselves post-pandemic and those they perceived should be adopted by the community. A subset of survey participants were interviewed (first quarter of 2022) with coded transcripts deductively mapped to the COM-B model and Theoretical Domains Framework. Results: 193 people (COPD 84, bronchiectasis 41, interstitial lung disease 35, asthma 33) completed the survey. Physical distancing indoors (83%), handwashing (77%), and avoidance of busy places (71%) or unwell family and friends (77%) were measures most likely to be continued. Policies for the wider community that received most support were those during the influenza season including hand sanitiser being widely available (84%), wearing of face coverings by healthcare professionals (67%) and wearing of face coverings by the general population on public transport (66%). Barriers to use of infection control measures were related to physical skills, knowledge, environmental context and resources, social influences, emotion, beliefs about capabilities and beliefs about consequences. Conclusions: Adults with chronic lung diseases in Australia are supportive of physical distancing indoors, hand hygiene, and avoidance of busy places or unwell family and friends as long-term infection control measures.
