The Health Information and Quality Authority has published 30 inspection reports on residential centres for older people.
They include inspection reports on a number of nursing homes which were severely impacted by Covid-19 in April.
In July, an inspection of Ryevale Nursing Home in Leixlip, Co Kildare, was conducted following the deaths of 40 residents due to suspected Covid-19.
The report notes that during the outbreak, 69 staff tested positive for the virus, which posed significant staffing challenges for two to three weeks at the peak of the outbreak in the centre.
At the time of the inspection all staff except two had recovered from Covid-19 and had returned to work.
The report says while the centre was visibly clean and decontamination cleaning of frequently touched surfaces was completed twice a day, the person in charge confirmed no decontamination cleaning of frequently touched surfaces was done between 4pm and 6am.
The report says actions were taken by the provider in all areas of non-compliance identified by inspectors.
In August, HIQA inspected Marymount Care Centre at Westmanstown in Lucan, Co Dublin, where 29 residents lost their lives due to Covid-19.
Inspectors found there were satisfactory staffing levels throughout the outbreak and that the loss of life in the centre had taken an emotion toll on staff and management.
At Larchfield Park Nursing Ltd in Naas, Co Kildare, there was an outbreak of Covid-19 which had impacted residents, staff and families according to HIQA.
There were 64 residents in the centre at the start of the outbreak. 41 residents tested positive for Covid-19, 20 residents passed away.
The report notes that during one week in April the service struggled to maintain nurse staffing levels in the centre but managed to maintain "a safe service" with the support of additional staffing from the Health Service Executive (HSE) and through sourcing staff from agencies.
In Donegal, inspectors found staff changes and a shortage of staff impacted negatively on the lives of those living at Mountain Lodge Nursing Home in Letterkenny.
During an unannounced inspection in August, inspectors found all bells were not being answered in a timely manner.
One resident described how they had been assisted to the toilet by a member of staff who had not ensured that the call bell was in reach to alert staff when they had finished on the toilet.
As a result, the resident waited for a long time and when the staff member did not return, they went back to their chair by themselves.
That resident told inspectors they were nervous about mobilising without the help of a member of staff and felt unsafe.
Other residents at the Mountain Lodge Nursing Home said they did not feel safe at night-time because two residents wandered at night.
They said these residents were not being supervised and were wandering into the bedrooms of other residents.
Due to staff shortages and low morale among staff members, residents said they felt the need to reassure the remaining staff and encourage them to stay on as part of the care team.
The report states that residents were genuinely concerned about the turnover of staff.
HIQA inspectors issued an "immediate action plan to the provider to increase staffing levels at the centre" and the report says this was acted on.
