2018 Sandbox Benchmark Scoring Seems Incorrect

[Randal Roe (Alpha II Registry)]

The attached text file is the response we received after a recent sandbox submission.

Quality measure 69 (Registry/QCDR submission), which starts at line 113 of the attached text file, has a performance rate of 83.33%. From the sandbox it received a decile score (achievement score) of 10 points:

                    "metadata": {

                      "performanceRate": 83.33,

                      "reportingRate": 97.67,

                      "measurementSetId": "03d0cbf4-27d4-43db-8f57-65f6f734db5f",

                      "measurementId": "03d0cbf4-4d59-44e1-a861-e699d52f2e80",

                      "measureClass": "Class 1",

                      "measureTitle": "Hematology: Multiple Myeloma: Treatment with Bisphosphonates",

                      "highPriorityBonusEligible": false,

                      "endToEndBonusEligible": false,

                      "endToEndBonus": 0,

                      "outcomeOrPatientExperienceBonus": 0,

                      "highPriorityBonus": 0,

                      "decileScore": 10,

                      "performanceDenominator": 84,

                      "performanceNumerator": 70,

                      "eligiblePopulation": 86,

                      "partialDecileScore": 0,

                      "partialPoints": 0,

                      "decile": -1,

                      "deciles": [

                        0,

                        100,

                        100,

                        100,

                        100,

                        100,

                        100,

                        100,

                        100

Looking at the benchmark file (also attached), we thought that a performance rate of 83.33% should result in a score of just the floor of 3 points, since all the deciles from 3 to 9 are empty. However, the sandbox returned a score of 10 points and assigned this measure to decile -1.

Our questions:

• For measure 69, wouldn't it require a performance rate of 100% to get a score of 10 points?
• Wouldn't anything less than 100% for the performance rate result in a score of 3 points (the "floor score")?
• What does "decile": -1 mean?
• In the "deciles" section, does each entry represent the left-side limit (the lower value for a non-inverse measures) of deciles 2-10?

Measure 110 seems to bear this out:

                      "deciles": [

                        0,

                        26.89,

                        40.49,

                        50,

                        57.07,

                        64.79,

                        73.08,

                        82.71,

                        96.44

                      ],

Thank you.

Just wondering if anyone has had a chance to review this?

Thanks.

Hi Randal,

We're looking into it. I'll let you know when I have more information to share shortly.
