The effect of the SARS-CoV2 pandemic and lockdown on non-Covid ICU admissions: Experience from a South African tertiary hospital.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Future pandemic planning involves analysing past experiences. We compared intensive care unit (ICU) admissions during the SARS-CoV-2 pandemic (2020) with the preceding year. Objectives: To assess the SARS-CoV-2 pandemic's effect on ICU admissions in a tertiary hospital, examining differences in patient characteristics, organ support requirements, reason for admission, mortality rates and length of ICU stay. Methods: This retrospective cohort study compared ICU patient data at a tertiary hospital during the SARS-CoV-2 pandemic (26 March 2020 to 20 September 2020) with the same period in 2019. Results: Patient admissions (p=0.39) and severity of illness (p=0.27 adults; p=0.92 paediatrics) showed no differences across the study period. Similarly, no differences were observed for underlying chronic conditions between the two years. Adult trauma admissions significantly declined, specifically those related to road traffic accidents (RR 0.63). Admissions for acute infectious conditions, including respiratory infections, sepsis, urosepsis, septic arthritis and gastroenteritis significantly declined in both adults (RR 0.50) and paediatric admissions (RR 0.25). During the lockdown period, the length of stay (LOS) decreased for adults, but mortality rates remained unchanged across the study period. The paediatric mortality rate decreased during the lockdown period (p=0.004). Conclusion: There was no reduction in SARS-CoV-2-negative ICU admissions during the 2020 lockdown period compared with the preceding year, likely due to chronic resource limitations. We found a decrease in acute trauma and acute infectious illness admissions, while acute surgical emergency admissions increased. These findings suggest that lockdown orders may have affected admission patterns, aiding in future pandemic planning. Contribution of the study: The study highlights the chronic shortage of critical care resources in South Africa and aids with future pandemic preparedness and planning in a resource limited setting.
