Epidemiology, outcomes, and utilization of intensive care unit resources for critically ill COVID-19 patients in Libya: A prospective multi-center cohort study

Abstract

Background The coronavirus disease (COVID-19) pandemic has severely affected African countries, specifically the countries, such as Libya, that are in constant conflict. Clinical and laboratory information, including mortality and associated risk factors in relation to hospital settings and available resources, about critically ill patients with COVID-19 in Africa is not available. This study aimed to determine the mortality and morbidity of COVID-19 patients in intensive care units (ICU) following 60 days after ICU admission, and explore the factors that influence in‐ICU mortality rate. Methods This is a multicenter prospective observational study among COVID-19 critical care patients in 11 ICUs in Libya from May 29th to December 30th 2020. Basic demographic data, clinical characteristics, laboratory values, admission Sequential Organ Failure Assessment (SOFA) score, quick SOFA, and clinical management were analyzed. Result We included 465 consecutive COVID-19 critically ill patients. The majority (67.1%) of the patients were older than 60 years, with a median (IQR) age of 69 (56.5–75); 240 (51.6%) were male. At 60 days of follow-up, 184 (39.6%) were discharged alive, while 281 (60.4%) died in the intensive care unit. The median (IQR) ICU length of stay was 7 days (4–10) and non-survivors had significantly shorter stay, 6 (3–10) days. The body mass index was 27.9 (24.1–31.6) kg/m2. At admission to the intensive care unit, quick SOFA median (IQR) score was 1 (1–2), whereas total SOFA score was 6 (4–7). In univariate analysis, the following parameters were significantly associated with increased/decreased hazard of mortality: increased age, BMI, white cell count, neutrophils, procalcitonin, cardiac troponin, C-reactive protein, ferritin, fibrinogen, prothrombin, and d-dimer levels were associated with higher risk of mortality. Decreased lymphocytes, and platelet count were associated with higher risk of mortality. Quick SOFA and total SOFA scores increase, emergency intubation, inotrope use, stress myocardiopathy, acute kidney injury, arrythmia, and seizure were associated with higher mortality. Conclusion Our study reported the highest mortality rate (60.4%) among critically ill patients with COVID-19 60 days post-ICU admission. Several factors were found to be predictive of mortality, which may help to identify patients at risk of mortality during the ongoing COVID-19 pandemic.

Epidemiologic Characteristics of and Prognostic Factors for COVID-19 Among Hospitalized Patients: Updated Implications From Hubei Province, China

“…Regarding other laboratory indicators with significance in univariate analyses in our study for which there was supporting evidence from national and international studies, WBC count ( 30 , 33 , 39 , 42 – 45 ), percentage of lymphocytes ( 8 ), PLT count ( 8 , 33 , 42 , 46 – 48 ), CRP level ( 8 , 33 , 43 , 46 , 48 , 49 ), neutrophil count ( 33 , 42 , 43 , 48 ), ALB level ( 33 , 43 , 49 ), blood UN ( 9 , 33 ), and blood glucose level ( 45 ) were also associated with prognosis. However, some significant laboratory parameters, such as lactate dehydrogenase ( 7 , 8 , 33 , 44 , 45 ), D-dimer ( 7 , 8 , 10 , 33 , 43 ), and procalcitonin ( 5 , 33 , 44 , 50 ), were not investigated in our study owing to a lack of data.…”

Factors influencing access and utilization of health services among older people during the COVID − 19 pandemic: a scoping review

“…The subthemes accommodated three concepts: acute COVID-19 services, the need for supplementary oxygen and ICU services. According to the data from studies contributing to this theme, there is a higher occurrence of acute respiratory distress syndrome [ 12 ] and a high risk of presenting complications from COVID-19 [ 11 ] and the particular need for ICU service [ 54 ]. are among the main aspects.…”

Modelling the cost-effectiveness of essential and advanced critical care for COVID-19 patients in Kenya

“…15 Further, outcomes for ACC are poor with only 39.6% recovering. 23 These factors combine to make an investment in critical care in addition to EC not cost-effective. These findings mirror a similar analysis carried out in South Africa that found purchasing additional ICU care during COVID-19 surges not cost-effective.…”
