Ireland's central source for Open Access health research

Lenus, the Irish Health Research repository is the leading source for Irish research in health and social care.  The Lenus collections include peer reviewed journal articles, grey literature, dissertations, reports and conference presentations. Lenus contains the publications of the Irish Health Service Executive (HSE) and the collected research output of over 130 health organisations past and present are all freely accessible.

Submit Your Research to Lenus 

If you are an Irish researcher or have conducted research in an Irish institution or health organisation, you can add your published research to Lenus. Submitted articles must be available in Open Access format or the publisher's policy must permit author self archiving. Advice on Open Access publishing and publishers' policies is available on the 'Open Access Publishing Guide' and 'Publishers' policies' pages available on the left-hand menu.     





HSE Open Access Research Awards 2021 - Enter Now

We are pleased to announce that the 2021 HSE Open Access Research Awards are now open.

This year has seen the Irish health services deal with a number of unprecedented challenges, from the massive cyber-attack in May to the rollout of the largest vaccination programme in the country’s history.

Through it all, clinicians and researchers have continued to deliver high quality healthcare – and to research new treatments, new advances in science and health, new ways of improving health outcomes.

The HSE Open Access Research Awards aims to shine a light on this activity and to thank those who have chosen to make their work available through Open Access, making their discoveries and advances freely available to all.


This year's awards will be in four categories:

Acute Care and Hospitals

Community and Social Care

Mental Health and Disabilities



Criteria for entry

Entries must fulfil the following criteria:

  • The research must have been published within the past two years (24 months)
  • The research must be available in full text in an Open Access forum (and added to the Lenus repository, pre or post entry)

  • Does high COVID-19 spread impact neighbouring countries? Quasi-experimental evidence from the first year of the pandemic in Ireland.

    Ahmed, Rakesh; May, Peter (2021-09-06)
    Background : Coronavirus disease 2019 (COVID-19) has necessitated public health responses on an unprecedented scale. Controlling infectious diseases requires understanding of the conditions that increase spread. Prior studies have identified sociodemographic, epidemiological and geographic associations. Ireland offers an unusual opportunity to quantify how high infection rates in one country impacted cases in a neighbouring country. Methods : We analysed official statistics on confirmed COVID-19 cases on the island of Ireland for 52 weeks from March 2020. Our main research question was: Did higher cases in Northern Ireland (NI) impact the number of cases in the Republic of Ireland (ROI)? We used least squares regression to compare confirmed cases in ROI counties that border NI with the rest of the state. We included in our model sociodemographic, epidemiological and geographic factors. We employed the latitude of each county town as an instrumental variable to isolate a quasi-experimental estimate of the cross-border spread. Results : In the quasi-experimental framework, and controlling for population density, age distribution and circulatory disease prevalence, border counties had an extra 21.0 (95%CI: 8.4-33.6) confirmed COVID-19 cases per 1000 people. This equates to an estimated 9,611 additional cases in ROI, or 4% of the national total in the first year of the pandemic. Our results were substantively similar in non-experimental frameworks, with alternative additional predictors, and in sensitivity analyses. Additionally, population density in ROI counties was positively associated with confirmed cases and higher proportions of residents in the professional classes was negatively associated. Conclusion : On the island of Ireland during the first year of the COVID-19 pandemic, high infection rates in NI increased cases in the neighbouring ROI. Maximising co-ordination of pandemic responses among neighbouring countries is essential to minimising disease spread, and its associated disruptions to society and the economy. Socioeconomic disadvantage appeared to confer significant additional risk of spread.
