Dataset Information

The effects of preoperative moderate to severe anaemia on length of hospital stay: A propensity score-matched analysis in non-cardiac surgery patients.

ABSTRACT:

Background

Anaemia is frequently recorded during preoperative screening and has been suggested to affect outcomes after surgery negatively.

Objectives

The objectives were to assess the frequency of moderate to severe anaemia and its association with length of hospital stay.

Design

Post hoc analysis of the international observational prospective 'Local ASsessment of VEntilatory management during General Anaesthesia for Surgery' (LAS VEGAS) study.

Patients and setting

The current analysis included adult patients requiring general anaesthesia for non-cardiac surgery. Preoperative anaemia was defined as a haemoglobin concentration of 11 g dl-1 or lower, thus including moderate and severe anaemia according to World Health Organisation criteria.
