Abstract

Introduction: Relationships between exacerbations of chronic obstructive pulmonary disease (COPD) and environmental factors such as temperature, humidity and air pollution are not well characterised, due, in part, to oversimplification in the assignment of exposure estimates to individuals and populations. New developments in miniature environmental sensors mean that patients can now carry a personal air quality monitor for long periods of time as they go about their daily lives. This creates the potential for capturing a direct link between individual activities, environmental exposures and the health of COPD patients. Direct associations then have the potential to be scaled up to population levels and tested using advanced human exposure models linked to electronic health records (EHRs). Methods and analysis: This study has five stages: 1) development and deployment of personal air monitors (PAM); 2) recruitment and monitoring of a cohort of 160 COPD patients for up to six months with recruitment of participants through the Clinical Practice Research Datalink (CPRD); 3) statistical associations between personal exposure with COPD related health outcomes; 4) validation of a time-activity exposure model; and 5) development of a COPD prediction model for London. Ethics and dissemination: The research ethics committee for Camden & Islington has provided ethical approval for the conduct of the study. Approval has also been granted by NHS Research & Development and the Independent Scientific Advisory Committee. The results of the study will be disseminated through appropriate conference presentations and peer reviewed journals.
