STITCH: Surgical Trial In Traumatic interCerebral Haemorrhage
At present it is known that patients with bleeding on the surface of the brain following a head injury benefit from urgent surgery but it is not known whether patients with bleeding inside the brain would also benefit from surgery or not. These patients have a poor outcome with between 30% and 60% dying, becoming vegetative or with severe disability at six months. Using a multicentre, randomised controlled design with economic analysis, this study provides some evidence for whether or not surgery is of benefit at reasonable cost to the NHS, for patients with bleeding or a bruise inside the brain following a head injury.
An economic evaluation, adopting an international health services perspective, was conducted alongside the randomised controlled trial to assess the relative costs and consequences of early surgery versus conservative management. Resource use and quality of life (QoL) data were collected from all centres across all countries. Results were presented as incremental costs (international dollars) per QALY gained, and compared to World Health Organization (WHO) guidelines on cost-effectiveness thresholds. Subgroup analyses were presented for low-, low-middle-, upper-middle- and high-income countries.
A policy of early surgery was on average more costly and more effective than conservative management, though differences between arms were not statistically significant. The base case incremental cost-effectiveness ratio was $50,541 per QALY gained. Results for the economic analysis were surrounded by considerable uncertainty.
Outcome and Translation
This study added to the international evidence base and informed the surgical community and other decision makers of the value of early surgery for traumatic intracerebral haemorrhage.
