Patterns of healthcare service utilisation following severe traumatic brain injury: An idiographic analysis of injury compensation claims data

Abstract

Background: The rate and extent of recovery after severe traumatic brain injury (TBI) is heterogeneous making prediction of likely healthcare service utilisation (HSU) difficult. Patterns of HSU derived from nomothetic samples do not represent the diverse range of outcomes possible within this patient group. Group-based trajectory model is a semi-parametric statistical technique that seeks to identify clusters of individuals whose outcome (however measured) follows a similar pattern of change over time. Aim: To identify and characterise patterns of HSU in the 5-year period following severe TBI. Methods: Detailed healthcare treatment payments data in 316 adults with severe TBI (Glasgow Coma S..
