TABLE 2.
Summary of the Pooled Estimates of Prevalence of Organ Replacement Among Adult Patients Hospitalized in the ICU
| Type of Replacement | No. of Studies | No. of Patients | No. With Replacement | Prevalence (%) | 95% CI | I2 (%) |
|---|---|---|---|---|---|---|
| Vasopressor use | 24 | 11,278 | 2,843 | 49.5 | 41.1–57.8 | 98 |
| Noninvasive mechanical ventilation | 29 | 7,784 | 1,531 | 20.9 | 13.8–30.5 | 98 |
| Mechanical ventilation | 53 | 25,243 | 17,662 | 62.4 | 57.8–66.7 | 98 |
| Extracorporeal membrane oxygenation | 27 | 9,159 | 568 | 6.2 | 4.7–8.1 | 85 |
| Continuous renal replacement therapy/dialysis | 28 | 21,629 | 5,057 | 19.9 | 17.6–22.4 | 90 |
Prevalence (%) is considered the pooled estimate of each organ replacement as calculated in the respective meta-analysis of the respective studies providing such data, taking into consideration different weights of each study in the meta-analysis (resulting from number of patients in each meta-analyzed trial).
