As the population in the Republic of Ireland increases, the number of Emergency Department (ED) attendances and admission rates increase, placing significant pressure on the health care system, the limited staff and hospital resources.

The aim of this study is to assess the admission rates in an Irish Public Hospital Emergency Department between 2014 and 2022.

This retrospective study was done using information provided by the Health Service Executive Integrated Patient Management System. Data for the period between February 2014 to September 2022 were collected. From the data, the admission rate can be calculated and trends observed.

Emergency department attendance rates have increased from 29,236 to 42,637 between 2014 and 2019, with a decline noticed in 2020 to 37,751 and a drastic increase in 2021 at 43,182. Currently up until September 2022 there has been 35,503 attendances and 8,570 admissions, with an admission rate of 24.14%. The number of admissions has ranged from 9,056 in 2014 to the highest being 12,175 in 2019. This means the admission rate is averaging between 24% to 31% per annum, with the highest being 31,04% in 2015, and the lowest in 2017 at 24,99%.

This study showed a steady increase in attendances per annum, which correlates to an increase in the total admissions from 2014 to 2022, with approximately one third of all ED attendances resulting in admission. The increase in attendances and admission rate could be related to the population growth from 4.6 to 5.1 million from 2014 to 2022. The decrease in attendances during 2020 could be attributed to the Covid-19 pandemic restrictions being implemented, and lifted in 2021 which showed a drastic increase in ED numbers. Ultimately, the increase in admissions will place a burden on the Public Hospitals in Ireland.
