So the question is: How can this data be anonymized so that it can still be used for training purposes?
The answer: with a system copy and the corresponding data alienation. Natuvion was able to successfully implement precisely this project in collaboration with a large hospital in southern Germany. Natuvion's solution for test data anonymization (DCS Protect) in SAP and non-SAP systems was used in combination with Empirius' solution for system copy (BlueCopy).
Relevant, but anonymized data
With the help of Empirius BlueCopy, a system copy of the hospital's productive system is automatically created every week. In this copy, the relevant data is then alienated by DCS Protect. In this way, the SAP IS-H/i.s.h.med training system will provide logical, consistent, but depersonalized data in the future. In addition, the time frame of the alienated data enables a look back and a look forward of the last four weeks and the next four weeks, respectively. As a result, this concept allows for the use of highly up-to-date cases in the training of physicians and staff.
Eliminating patient interference
In total, about 70,000 patient, 80,000 physician, and 1 million medical treatment records are alienated each week as part of this project. The data signifies that the patient and case numbers have been changed in all tables. Furthermore, no person can be identified by name, date of birth, address, next of kin, payer, primary care physician, insurance number, or patient or case number anymore. In addition, approximately 4,000 fields and 400 tables in the training system itself will be anonymized. Using ILM blocking, an additional 1.7 million patients are also blocked, as well as payers, debtors, and suppliers. The non-training-relevant data is thus hidden from the system.
