XDS Statistics - October 2024

In this month's blog about the metrics of the Dutch XDSCloud service, you may notice the new diagrams. Over the last months, we have developed a new dashboard to visualize the KPIs through our platform's console. This dashboard is being made available to our customers. 

KPI 1 - Registered Document Volume

This KPI gives insights into the total amount of XDS documents that are available within the XDSCloud infrastructure. Since each XDS document represents a certain type of clinical information it is broken down into different document types. Each type refers to a specific (set of) XDS document formatCodes (e.g. DICOM Key Object, Medical Summary, Basic Patient Privacy Consent, etc.).

KPI 2 & 3 - Total number of exchanged DICOM Studies & (XDS) Documents 

These KPIs give insights into the amount of DICOM Studies and Documents that are exchanged across different healthcare institutions that are part of the Dutch XDSCloud infrastructure. It does not include any exchanges within a healthcare enterprise. Only the "provide" volume is counted as an indication of the total volume that healthcare institutions share among each other. Each provided study or document is either received by another XDSCloud node, or is received by a healthcare institution in an external network outside the XDSCloud infrastructure.

The first diagram shows the amount of DICOM studies exchanged over the last three months. The second diagram shows a similar picture for the amount of exchanged (XDS) documents.

Figure 3, Document Exchange

Both the amount of exchanged DICOM studies (10,762), as well as the amount of exchanged documents (82,706) was slightly below October, and inline with the number in September. 

KPI 4 - Number of registered patient identifiers

This KPI gives insights into the total number of unique patients registered at each institution. As the data this KPI is based on is anonymised it is not traceable to individual patient records. Hence, the total number across all institutions cannot be corrected for duplicates. We therefore track both the Dutch unique Patient Identifier (referred to as BSN), and the health institution (local) Patient MRN.

The delta between the two indicates how many patients are registered without a known BSN. In absolute terms the number of local identifiers gives an indication of how many patient records are available and potentially accessible when complying with local data privacy regulations.
