Investigating the cost-effectiveness of health information technologies: a systematic review protocol

Data extraction

Data will be abstracted onto a customised data extraction sheet by two independent reviewers; any disagreements will be resolved through discussion, with arbitration by a third reviewer if necessary. Variables to be extracted will include: author and year; title of the study; country of origin; healthcare setting; HIT application(s); estimates of costs and cost-effectiveness; time frame over which evaluations are undertaken; lessons learned. Key findings from each study will be summarised and presented in summary tables.
