June 20, 2025: Enhanced Support for Summarizing and Displaying Admitting and Emergency Location and Date Time in the Transition of Care Lens

The Transition of Care (ToC) Lens now has enhanced support for summarizing and displaying admitting and emergency location information, including associated date and time within the EpisodeOfCare resources.

The extension admittingLocation shall provide the location of the latest inpatient (IMP) encounter from the group of aggregated encounters comprising the ToC Lens. This extension ignores IMP encounters with no location or no hospitalization.reAdmission field. It also includes the admission time for that encounter using the period start:

  "extension": [  
    {  
      "url": "https://zusapi.com/lens/extension/admittingLocation",  
      "valueReference": {  
        "display": "General Health",  
        "reference": "Location/8d99aeb1-e35d-4cd9-9ab9-76496420ab59",  
        "type": "Location"  
      }  
    },  
    {  
      "url": "https://zusapi.com/lens/extension/admissionDatetime",  
      "valueDateTime": "2025-04-13 23:33:00Z"  
    }  
  ]  
},

The emergencyLocation extension includes a nested emergencyLocationEndDateTime which contains the period end of the latest emergency encounter in the ToC.

        "reference": "Location/7c80add0-d24c-3bc8-8ce9-65385209li76",  
        "type": "Location"  
      },  
      {

        "valueDateTime": "2025-04-13 19:00:00Z"  
      }  
    }  
  ]  
},
