Prospective study of 2,646 ICU patients ≥70 years old, showing no significant difference in mortality with acetaminophen use in the 10 days prior to ICU admission. Acetaminophen is also known as paracetamol, Tylenol, Panadol, Calpol, Tempra, Calprofen, Doliprane, Efferalgan, Grippostad C, Dolo, Acamol, Fevadol, Crocin, and Perfalgan.

Background: In the early COVID-19 pandemic concerns about the correct choice of analgesics in patients with COVID-19 were raised. Little data was available on potential usefulness or harmfulness of prescription free analgesics, such as paracetamol. This international multicentre study addresses that lack of evidence regarding the usefulness or potential harm of paracetamol intake prior to ICU admission in a setting of COVID-19 disease within a large, prospectively enrolled cohort of critically ill and frail intensive care unit (ICU) patients. Methods: This prospective international observation study (The COVIP study) recruited ICU patients ≥ 70 years admitted with COVID-19. Data on Sequential Organ Failure Assessment (SOFA) score, prior paracetamol intake within 10 days before admission, ICU therapy, limitations of care and survival during the ICU stay, at 30 days, and 3 months. Paracetamol intake was analysed for associations with ICU-, 30-day-and 3-month-mortality using Kaplan Meier analysis. Furthermore, sensitivity analyses were used to stratify 30-day-mortality in subgroups for patient-specific characteristics using logistic regression. Results: 44% of the 2,646 patients with data recorded regarding paracetamol intake within 10 days prior to ICU admission took paracetamol. There was no difference in age between patients with and without paracetamol intake. Patients taking paracetamol suffered from more co-morbidities, namely diabetes mellitus (43% versus 34%, p < 0.001), arterial hypertension (70% versus 65%, p = 0.006) and had a higher score on Clinical Frailty Scale (CFS; IQR 2-5 versus IQR 2-4, p < 0.001). Patients under prior paracetamol treatment were less often subjected to intubation and vasopressor use, compared to patients without paracetamol intake (65 versus 71%, p < 0.001; 63 versus 69%, p = 0.007). Paracetamol intake was not associated with ICU-, 30-day-and 3-month-mortality, remaining true after multivariate adjusted analysis.
Elisabeth-Krankenhaus Essen Essen Declarations Ethics approval and consent to participate The primary competent ethics committee was the Ethics Committee of the University of Duesseldorf, Germany (application number 2020-892). Each participating center received a copy of the study protocol. Institutional research ethic board approval was obtained from each study site and was mandatory for study participation. Due to the observational nature of the study, participation in this study did not impact medical procedures, which were all executed in accordance with the relevant medical guidelines and regulations. No additional examinations, e.g., sampling and storage of biomaterials, such as blood or CT-scans and X-rays, were performed. The study was planned in adherence to the European Union General Data Privacy Regulation (GDPR) directive, which is implemented in most participating countries. Deceased patients were included within strict consideration of local requirements set up by the local ethics committees. However, in a few countries, recruitment was possible without informed consent in accordance with the respective local ethics committee (see above).
