Abstract:

Questions of how to measure outcomes are commonly heard in rehabilitation today. In this supplement we review the current state of the art of outcomes measurement in traumatic brain injury rehabilitation, discuss key issues, and identify steps that need to be taken. The underlying question is not simply that of outcomes measurement but how to infer effective and cost-effective treatment. The validity of such inferences rests on multiple features of the entire clinical information system. Requirements for valid, feasible, outcome-oriented clinical data systems are described. Effectiveness is inferred from variations in outcomes experienced by similar persons who received differing interventions. Outcome data systems need large sample sizes and technically adequate severity adjusters. A nationwide TBI data system is needed to identify reasonably homogeneous subgroups in different programs whose outcomes can be meaningfully compared. In alliance with payors and persons with disabilities, rehabilitation professionals can create outcome data systems that will provide the knowledge necessary to improve the effectiveness and cost-effectiveness of rehabilitation programs.
