| Units for Reporting: | N/A | ||||||||
| Samples Distributed: | 2 sets of digital images representing 2 different cases. | ||||||||
| Number of Distributions per year: | 4 | ||||||||
| Number of Samples per Distribution: | 2 digital samples per distribution | ||||||||
| Frequency of Distributions: | Every 12 weeks as outlined in the Distribution Schedule | ||||||||
| Schedule of Analysis: | Access to the digital images is via the web and includes the submission of interpretations. Data analysis commences 21 days after release of case. Late returns cannot be accepted. | ||||||||
| Data Analysis: | Qualitative responses are assessed in terms of MI scoring for each scoring element in relation to the Designated Response. | ||||||||
| Performance Scoring: | MI Scoring | ||||||||
| Criteria of Performance: |
Laboratory performance is classified in terms of OMIS derived from the qualitative responses for:
over a running analytical window of 4 Distributions (12 months) The categories of performance are:
An OMIS of 2 or more for any one analyte will be classed as poor performance. |
||||||||
| Persistent Poor Performance: | Defined as being in the Poor Performance category for two or more successive distributions |
