Abstract

Epidemiology, ventilator management, and outcome in patients receiving invasive ventilation in intensive care units (ICUs) in middle-income countries are largely unknown. PRactice of VENTilation in Middle-income Countries is an international multicenter 4-week observational study of invasively ventilated adult patients in 54 ICUs from 10 Asian countries conducted in 2017/18. Study outcomes included major ventilator settings (including tidal volume [VT] and positive end-expiratory pressure [PEEP]); the proportion of patients at risk for acute respiratory distress syndrome (ARDS), according to the lung injury prediction score (LIPS), or with ARDS; the incidence of pulmonary complications; and ICU mortality. In 1,315 patients included, median VT was similar in patients with LIPS < 4 and patients with LIPS 3 4, but lower in patients with ARDS (7.90 [6.8–8.9], 8.0 [6.8–9.2], and 7.0 [5.8–8.4] mL/kg Predicted body weight; P = 0.0001). Median PEEP was similar in patients with LIPS < 4 and LIPS 3 4, but higher in patients with ARDS (five [5–7], five [5–8], and 10 [5–12] cmH2O; P < 0.0001). The proportions of patients with LIPS 3 4 or with ARDS were 68% (95% CI: 66–71) and 7% (95% CI: 6–8), respectively. Pulmonary complications increased stepwise from patients with LIPS < 4 to patients with LIPS 3 4 and patients with ARDS (19%, 21%, and 38% respectively; P = 0.0002), with a similar trend in ICU mortality (17%, 34%, and 45% respectively; P < 0.0001). The capacity of the LIPS to predict development of ARDS was poor (receiver operating characteristic [ROC] area under the curve [AUC] of 0.62, 95% CI: 0.54–0.70). In Asian middle-income countries, where two-thirds of ventilated patients are at risk for ARDS according to the LIPS and pulmonary complications are frequent, setting of VT is globally in line with current recommendations.
