A suite of reports, based on data from The Irish Longitudinal Study on Ageing (TILDA), has been published to assist Government and the health services to plan and deliver the response to the COVID-19 pandemic in Ireland. The reports respond to emerging national and international data on key risk factors associated with COVID-19.

The reports estimate how common these factors are in Ireland and highlight where additional community services and supports may be required, particularly in the context of the recent ‘cocooning’ policy.

Researchers have examined the numbers of people aged 50 years and older living in the community with one or more chronic conditions such as high blood pressure, lung disease, diabetes, kidney disease and cancer; the commonness of smoking; rates of high-risk medication usage (steroids, immune therapies); numbers of frail persons and their living arrangements, i.e. living alone; and rates of utilisation of a range of health and social care services. The reports are part of a concerted effort by the Trinity College TILDA team to provide rapid analysis of its latest data to inform and assist the national response to the COVID-19 crisis.

Professor Rose Anne Kenny, Principal Investigator of TILDA, said: “Older persons and those with pre-existing chronic conditions are most likely to experience severe consequences from COVID-19. Because immune defences decline and chronic disease rises with age, people aged 70 and older are at particularly high risk. The purpose of the reports is to raise awareness of how common these high-risk groups are, nationally and at a county level, and how many people are at highest risk, i.e. have 3 or more chronic conditions or have frailty. Furthermore, the services currently being used and possible additional service requirements of vulnerable persons are detailed for each county.”

The first of the reports, “High-risk categories for COVID-19 and their distribution by county in Republic of Ireland,” details that the following conditions are common in people aged 50 and older:

• Almost 750,000 adults have hypertension (over 50%).
• Over 308,000 adults have asthma or chronic lung disease (20%).
• 183,000 adults have diabetes mellitus (13%).
• 129,000 adults have chronic kidney disease (10%).
• 167,500 adults have past or present cancer (12%).
• 638,000 adults nationally, and over 30% of over 70s, live with three or more chronic diseases.

People who are frail are at increased risk of unpredictable health deterioration following infection.

The second report, “TILDA Report on Population Estimates of Physical Frailty in Ireland to Inform Demographics for Over 50s in Ireland during the COVID-19 Pandemic,” focuses on people who are frail:

• Frailty is most common in people 70 and older: 80,600 of 191,880 (total number over 70) are frail.
• Over half of frail adults aged 70 and older (44,500; 55%) do not have any form of informal care or formal support.
• 12,200 over 70s are living alone with frailty. This is 28% of the population over 70 living alone.
• Urban centres have more of the adult population with physical frailty than rural areas. The highest numbers are in Dublin (18,000) and Cork (13,500), and the lowest in Carlow (300) and Offaly (200).

The third report, “Patterns in service utilisation: results from Wave 5 of The Irish Longitudinal Study on Ageing (TILDA),” finds:

• The most commonly used service by older adults is their General Practitioner (GP). 93% of the population aged 50 or older (approximately 1,346,370 people) reported seeing their GP at least once in the previous 12 months, increasing to 97% among adults aged 70 or older (approximately 413,630 people). Adults aged 50 or older made on average 3.9 visits to their GP in the previous year. This figure changed by age group, to 3.4 visits for adults aged 50 to 69, and 4.4 visits for adults aged 70 or older.
• A larger proportion of adults aged 70 years or older use home care and the Public Health Nurse (PHN) service compared to adults aged 50 or older. 4.3% of adults aged 50 or older reported having received home care, increasing to 8.3% of adults aged 70 years or older. Similarly, 4.5% of adults aged 50 or older reported having received a visit from the PHN, increasing to 7.9% of adults aged 70 or older.
• The most frequently used of State-provided community services in 2018 were optician services, where nationally 14.6% (approx. 211,770) adults aged 50 or older utilised this service.
• Speech and language therapy was the least used community service; 0.35% (approx. 4,920) adults aged 50 or older utilised this service in 2018.
• 19.7% of adults aged 50 or older (approximately 284,810 people) reported visiting the Emergency Department (ED) at least once in the previous 12 months, increasing to 22.5% among adults aged 70 or older (approximately 95,890 people). The average number of visits to the ED was 0.27 visits for adults aged 50 or older, 0.23 for adults aged between 50 and 69, and 0.32 for adults aged 70 or older.
• The average number of overnight hospital admissions was also associated with age; 0.28 for adults aged 50 or older, 0.20 for adults aged between 50 and 69, and 0.35 for adults aged 70 or older.
