XDS Statistics - February 2024
As part of our monthly series, we are sharing 4 Key Performance Indicators (KPIs) to better understand the value that Founda's XDSCloud solution offers. Here are the KPIs for the month of February, 2024 for XDSCloud in the Netherlands.
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 gives insights into the amount of DICOM Studies and Documents that are exchanged across different healthcare institutions that are part of the 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 of 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 period of three months. The second diagram shows a similar picture for the amount of exchanged (XDS) documents. The exchange document volume is approx. 6-7 times higher than the amount of DICOM studies exchanged.
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 therefor 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.
Conclusions
The slightly lower exchange numbers in Feb are due to the fact that Feb has 2 days less this year compared to Jan. If you would extrapolate the number with two additional days with an average volume Feb would be slightly higher than Jan.
For example, if we extrapolate "DICOM study exchange volume" of Feb for 31 days = 10,306 / 29 = 355 per day * 2 days = 710
Therefore the extrapolated total for 31 days is 10306 + 710 = 11,016 (compare with Jan: 10,749).
