As the population ages, an increasing proportion of the neurosurgical caseload is comprised of older patients. This trend is reinforced by technical advances and anaesthetic considerations within the field, allowing a higher proportion of patients eligible for surgery. Comprehensive geriatric assessment (CGA) is the gold standard clinical approach for evaluating older patients. Peri-operative care of older people (POPS) has provided strong evidence that CGA services can result in fewer post-operative complications. However, this evidence stems largely from trauma and orthopaedic surgery. Currently, there is little evidence of the impact CGA has on older neurosurgical patients. The study aimed to investigate whether CGA for older neurosurgical patients improved outcomes such as thirty-day mortality and length of stay. A control group was established by collecting retrospective data for all acute neurosurgical patients over the age of 65. This was then compared with an intervention group who received CGA in the form of regular geriatric consultant reviews. 49 patients were recruited into each group. Analysis showed that the interventional group had a significantly higher mean age and level of frailty. They also had more confirmed complications with a significant difference in the diagnosis of pneumonia (p = 0.05) and hyponatremia (p = 0.015). Despite this, the thirty-day mortality was lower and average length of stay was on average two days shorter compared to the control group, although this did not reach statistical significance (p = 0.701). The study showed that more patients who received a CGA were discharged home (p = 0.209). Our findings suggest that CGA input for older neurosurgical patients improves outcomes and should be incorporated routinely into neurosurgical clinical pathways.
