Aim Cardiovascular (CVD) and respiratory (RSD) diseases are leading causes of morbidity and mortality in Ireland. Clear links have been demonstrated in the literature between poor air quality and these diseases. This study aimed to use routinely available data to examine the relationship between air quality index for health (AQIH) (Available URL: http://www.epa.ie/air/quality/index/) and hospital admissions due to CVD and RSD in Dublin City and County between 2014 and 2018. Methods Admission data were collected from the HSE Hospital In-Patient Enquiry (HIPE). Daily count of hospital admissions with Dublin city and county address with a primary diagnosis of CVS and RSD was performed. The daily AQIH were obtained from the EPA for Dublin. Results Overall, AQIH distribution was: Good: 96% (1,575/1,642); Fair: 3% (52/1,642); and Poor: 1% (11/1,642). There were significant rises in admissions with change in AQIH (i.e. from good to very poor) for asthma, chronic obstructive airways disease and heart failure. There were also varying significant changes in short-term admission rates (i.e. up to 72 hours) following change in AQIH. Conclusions This study, using routinely gathered data, suggests that in Dublin city, where the AQ is predominantly good, that change in ambient AQ appears to impact admissions with CVD and RSD.
