As per guidance:

The logic supports extraction of the FIRST set of HWR-specific core clinical data elements in two different ways depending on if the patient was a direct admission, meaning that the patient was admitted directly to an inpatient unit without first receiving care in the emergency department or other hospital outpatient locations within the same admitting facility: 

1. If the patient was a direct admission, the logic supports extraction of the FIRST resulted vital signs within 2 hours (120 minutes) after the start of the inpatient admission, and the FIRST resulted laboratory tests within 24 hours (1440 minutes) after the start of the inpatient admission. 
2. If the patient has values captured prior to admission, for example from the emergency department, pre-operative, or other outpatient area within the hospital, the logic supports extraction of the FIRST resulted vital signs and laboratory tests within 24 hours (1440 minutes) PRIOR to the start of the inpatient admission. All clinical systems used in inpatient and outpatient locations within the hospital facility should be queried when looking for core clinical data element values related to a patient who is subsequently admitted.

Query: 
The cql section of the measure guides us to check Body weight during Interval[start of Encounter.relevantPeriod - 1440 minutes, start of Encounter.relevantPeriod + 1440 minutes]. However guidance states vital signs should be checked within 2 hours (120 minutes) after the start of the inpatient admission.

Kindly let us know what should be the validation time period for checking Body weight. Should Body weight be limited between 24 hours(- 1440 minutes) prior to Inpatient admission and 2 hours(120 minutes) after inpatient admission?

Request you to assist us on the above queries urgently as client deliverables are dependent upon it.
