A national survey on routines regarding sedation in Swedish intensive care units

Background: Previous studies concerning sedation in Swedish intensive care units (ICU) have shown variability in drug choices and strategies. Currently, there are no national guidelines on this topic. As an update to a Nordic survey from 2004, and as a follow-up to a recently introduced quality indicator from the Swedish Intensive Care Registry, we performed a national survey. Methods: A digital survey was sent to the ICUs in Sweden, asking for sedation routines regarding hypnosedatives, analgosedatives, protocols, sedation scales, etc. Results: Fifty out of 80 ICUs responded to the survey. All units used sedation scales, and 88% used the RASS scale; 80% used written guidelines for sedation. Propofol and dexmedetomidine were the preferred short-term hypnosedatives. Propofol, dexmedetomidine, and midazolam were preferred for long-term hypnosedation. Remifentanil, morphine, and fentanyl were the most frequently used agents for analgosedation. Conclusions: All ICUs used a sedation scale, an increase compared with previous studies. Concerning the choice of hypno- and analgosedatives, the use of dexmedetomidine, clonidine, and remifentanil has increased, and the use of benzodiazepines has decreased since the Nordic survey in 2004

Susceptibility to SARS-Cov-2 infection and risk for severe COVID-19 in patients with prostate cancer on androgen deprivation therapy

Androgen deprivation therapy (ADT) has been hypothesized to protect against COVID-19, but previous observational studies of men with prostate cancer on ADT have been inconsistent regarding mortality risk from coronavirus disease 2019 (COVID-19). Using data from the Prostate Cancer data Base Sweden (PCBaSe), we identified a cohort of 114 547 men with prevalent prostate cancer on the start of follow-up in February 2020, and followed them until 16 December 2020 to evaluate the association between ADT and time to test positive for COVID-19. Among men testing positive for COVID-19, we used regression analyses to estimate the association between ADT and risk of COVID-19-related hospital admission/death from any cause within 30 days of the positive test. In total, 1695 men with prostate cancer tested positive for COVID-19. In crude analyses, exposure to ADT was associated with a 3-fold increased risk of both testing positive for COVID-19 infection and subsequent hospital admission/death. Adjustment for age, comorbidity and prostate cancer risk category substantially attenuated the associations: HR 1.3 (95% CI: 1.1-1.5) for testing positive for COVID-19, and OR 1.4 (95% CI: 1.0-1.9) for risk of subsequent hospital admission/death. In conclusion, although these results suggest increased risks of a positive COVID-19 test, and COVID-19-related hospital admission/death in men on ADT, these findings are likely explained by confounding by old age, cancer-associated morbidity and other comorbidities being more prevalent in men on ADT, rather than a direct effect of the therapy

Immigrant background and socioeconomic status are associated with severe COVID-19 requiring intensive care

Abstract To determine whether immigrant background and socioeconomic status were associated with increased risk to develop severe Coronavirus disease 2019 (COVID-19) requiring mechanical ventilation at the intensive care unit and to study their effects on 90-day mortality. Nationwide case–control study with personal-level data from the Swedish Intensive Care register linked with socioeconomic data from Statistics Sweden and comorbidity data from the national patient register. For each case of COVID-19 treated with mechanical ventilation at the intensive care unit (outcome), 10 population controls were matched for age, sex and area of residence. Logistic and Cox regression were used to study the association between the exposure (immigrant background, income and educational level) and 90-day mortality. In total, 4 921 cases and 49 210 controls were matched. In the adjusted model, the risk of severe COVID-19 was highest in individuals born in Asia (Odds ratio [OR] = 2.44, 95% confidence interval [CI] = 2.20–2.69), South America (OR = 2.34, 95% CI = 1.82–2.98) and Africa (OR = 2.11, 95% CI = 1.76–2.50). Post-secondary education was associated with a lower risk of severe COVID-19 (OR = 0.75, CI = 0.69–0.82) as was the highest (vs. lowest) income quintile (OR = 0.87, CI = 0.77–0.97). In the fully adjusted Cox-regression analysis birth region of Africa (OR 1.38, CI = 1.03–1.86) and high income (OR 0.75, CI 0.63–0.89) were associated with 90-day mortality. Immigrant background, educational level and income were independently associated with acquiring severe COVID-19 with need for mechanical ventilation
