Intensive care utilisation after elective surgery in Australia and New Zealand: getting the balance right.

Of the total intensive care unit (ICU) admissions in Australia and New Zealand, 36.6% occur following an elective surgical procedure. How best to use ICU services in this setting is not clear, despite this being an expensive and resource-intensive method of care delivery. The literature relating to this area has not demonstrated a clear association between improved outcomes and routine ICU utilisation. It has, however, demonstrated that methods of care delivery in this setting vary at the local, national and international level. There is now an increased interest in how we can offer safe, efficient care to patients who need ICU-level support after elective surgery, as well as where and when that care can be offered. We had previously performed a literature review relating to ICU utilisation in the elective surgical post-operative setting. This perspective piece arises from this literature review as well as extensive clinical experience from the authors. We discuss the need for a move towards an evidence-based indication for ICU admission and how this may be achieved. We then move on to the various alternative models of care that could be offered, briefly discussing their positives and potential drawbacks. We finish by outlining the research priorities and how these might be implemented in clinical practice. Getting the balance right between ICU admission and higher acuity ward-level care for post-operative elective surgical patients is difficult. However, this is an important challenge that we as a healthcare community must be working to answer.
