ConclusionsД¬autiously, semi-recumbent seems to be the best position to reduce VAP incidence, hospital length of stay and the duration of MV. The ranking probabilities and the surface under the cumulative ranking displayed as the first best option of treatment the semi-recumbent position to reduce the incidence of VAP (71.4%), the hospital length of stay (68.9%), and the duration of MV (67.6%) and the prone position to decrease the mortality (89.3%) and to reduce the ICU length of stay (59.3%). Semi-recumbent and prone positions showed a risk reduction of VAP incidence (RR: 0.38, 95% CI: 0.25вЂ“0.52) and mortality (RR: 0.70, 95% CI: 0.50вЂ“0.91), respectively, compared to the supine position. The assessed interventions were different body positions (i.e., lateral, prone, semi-recumbent) or alternative degrees of positioning in mechanically ventilated patients. We performed a network meta-analysis of randomized controlled trials including intubated patients undergoing MV and admitted to an ICU. The aim of this study was to know what the best body position is to prevent VAP, shorten the length of intensive care unit (ICU) and hospital stay, and reduce mortality among patients undergoing mechanical ventilation (MV). The evidence about the best body position to prevent ventilator-associated pneumonia (VAP) is unclear.
