Introduction:

Platelet mean volume (MVP) is a biomarker used in the integral approach to sepsis.

Objective:

To assess the association between MVP and mortality in patients with sepsis.

Methods:

A systematic review of observational studies in five databases was performed. Mortality associated with sepsis was analysed; interventions considered were MPV, APACHE and serum lactate.

Results:

Regarding mortality associated with sepsis, a significant value was found in the MVP at 72 hours (200 deceased versus 654 not deceased; MD 0.83 IC95% 0.53-1.13, p=<0.0001, I2 =72.9%); as well as the value of APACHE II (220 dead versus 604 not deceased; MD 0.81 IC95% 0.62-1.0, p= 0.0001, I2 =32%). No statistical significance was found for the other clinical variables.

Conclusions:

Increased MVP is associated with increased risk of mortality in patients with sepsis, especially after 72 hours of evolution of clinical features.
