Previous studies have demonstrated an increased risk to elderly patients undergoing surgery, with high rates of unplanned admission to intensive care units, longer duration of hospital stay and mortality.1 Less well understood, however, is how specific preoperative characteristics of older patients predispose to these adverse postoperative outcomes. With the global population ageing, identifying these factors will become increasingly important to the delivery of safe perioperative care. This study examined the prognostic value of a range of preoperative patient characteristics on elective surgical outcomes.2


This was a systematic review and meta-analysis of prospective studies evaluating adults aged ≥60 years undergoing any type of elective surgery, reporting prognostic factors associated with adverse postoperative outcomes. The outcomes included mortality, functional decline, prolonged length of hospitalisation, discharge to a location other than home and …
