In the Shannonside region, 101 women accessed abortion services in hospitals or medical centres last year - down from 133 on 2020 statistics

38 women from Roscommon accessed abortion services in Ireland last year down from a total of 53 in 2020.
There was also drop in the figures for Longford last year compared to 2020 as the total dipped from 52 to 41 year on year.

It says this coincided with the cyberattack on the HSE - and says that's likely to have led to the large reduction in notifications during that period.
