Mr. Phelim Quinn:

We would have contracts with specific agencies that were tendered for under proper procurement processes. The critical issues in 2016 with regard to the increase in agency staff related to a number of specific issues. I referred in the opening statement to the national patient experience survey. We engaged a number of agency staff as part of the development of the survey and its methodology. Similarly, during the course of 2016 and 2017, we developed a new or enhanced approach to monitoring which makes our assessments and judgments more evidence-based. We had some agencies to backfill our own expertise to enable and free up some of that expertise in-house. We have used agencies for very specific issues over the course of 2016 that I believe can be accounted for.
