Queensland Health director-general Michael Walsh has announced his resignation over ongoing issues with the department’s $1.5 billion rollout of an integrated electronic medical record system.

The ieMR system is a single state-wide database for patient records, but the project has faced cost blowouts, delays and caused concern among clinicians over the software’s safety.

Queensland Health Minister Steven Miles thanked Mr Walsh for his work, and says a search for his replacement is currently underway.
