| Impact: | Often the time is not included when documenting onset dates for Problems, Allergies and historical medications. The time will always be defaulted to midnight for these datetime values. This inclusion of the midnight time could alter the time interval calculation result. |

| Description |
|
Logic Guidance for the 2019 reporting year: Appendix B. Time Interval Definitions and Examples The 2018 reporting year Logic Guidance included this note in timing calculations definitions - "For the purposes of quality measures, duration expressed in years ignores the time of day associated with the date/time stamps used in the calculation" However, in the 2019 reporting year Logic Guidance, that note has been removed. The CQL definition now includes time of day in each of the calculations "any time interval which starts at a certain time of day". This means that all timing calculations must consider the time of day when calculating the time interval when "any time interval which starts at a certain time of day" is specified in the definition? Year, Month, Week, Days? |

With CQL, the precision at which the timing comparison is performed can be specified as part of the timing phrase (e.g. prevalencePeriod starts before day of start of relevantPeriod). If no precision is specified in the timing phrase (e.g. prevalencePeriod starts before start of relevantPeriod), the comparison is performed based on the precision of the values involved. So if the values for onset are being defaulted to midnight, and the timing phrases in the measures do not specify a precision, then yes, the comparisons will include time.
