Ethnic disparities and COVID-19 pneumonia in Ireland: a single-centre descriptive study of hospitalised patients in a tertiary university teaching hospital

Abstract

In this study, we aim to describe the demographic, clinical and imaging characteristics, treatment course and subsequent outcomes of the first 116 cases presenting to a tertiary Dublin hospital with COVID-19 infection and to compare whether ethnic minority background was a risk factor for poorer disease outcomes in this cohort. Of 116 cases analysed, 100 (86%) patients presented from the community, 6 (5%) from care homes and 10 (9%) were existing inpatients. Fifty-four (46%) patients identified as being from an ethnic minority group. One hundred fourteen (98%) patients reported two or more symptoms at time of diagnosis with 81 (70%) patients having confirmed radiological findings of COVID-19 infection. Median duration of symptoms prior to hospital presentation was 6 days (IQR 3–10 days). The median age at presentation was 52 years (IQR 43–65). Co-morbidities recorded included hypertension, hyperlipidaemia, type 2 diabetes mellitus, underlying respiratory disease, previous or current malignancy and current smoker. Twenty-six patients (22%) required ICU admission, 20 (76.9%) of these were from all other ethnic groups combined and 6 (10%) from White Irish group. Adjusting for variables of age, ethnicity and gender, all other ethnic groups combined were five times more likely to require ICU admission than White Irish group (Table 5). Patients from all other ethnic groups combined admitted to ICU were significantly younger than patients from White Irish group (OR 50.85 vs 62.83, P = 0.012). Our hospital’s catchment area serves a wide-ranging and diverse population with many ethnic minority groups represented. Our data demonstrated that there was a significant overrepresentation of a younger cohort of patients from ethnic minority groups admitted to ICU with COVID-19 infection with less co-morbidities than that of the White Irish group.
