Design and Implementation of an ETL-Process to Transfer Wound-Related Data into a Standardized Common Data Model
In this study an ETL process for the transition of wound related data was developed. After understanding the data in general and mapping the relevant codes to concepts available in OMOP, the ETL process was implemented. In a first step, a generic algorithm to convert data to a csv format was implemented in Java. The resulting csv file was then processed within KNIME to be loaded into an OMOP CDM conformant database. During the whole ETL process, HL7 FHIR CodeSystem and ConceptMap resources were used for coding and mapping. First clinical test cases to retrieve data were successfully processed as an example to demonstrate t...

Towards a Recommendation for Good Health Data Modeling (GHDM) - Results of Expert Interviews
Stud Health Technol Inform. 2023 Sep 12;307:215-221. doi: 10.3233/SHTI230716.ABSTRACTAppropriate data models are essential for the systematic collection, aggregation, and integration of health data and for subsequent analysis. However, recommendations for modeling health data are often not publicly available within specific projects. Therefore, the project Zukunftslabor Gesundheit investigates recommendations for modeling. Expert interviews with five experts were conducted and analyzed using qualitative content analysis. Based on the condensed categories "governance", "modeling" and "standards", the project team generated ...

Menstrual Cycle Tracking Apps: An Applied Combined Medical and Data Privacy Scoring
Stud Health Technol Inform. 2023 Sep 12;307:208-214. doi: 10.3233/SHTI230715.ABSTRACTToday, many menstruating individuals track their cycles with mobile apps. These cycle apps use a lot of highly sensitive personal data. The goal of this study is to evaluate current cycle apps based on data privacy and medical criteria. First, a market analysis of currently available apps was conducted. Second, a scoring system was developed based on Digital Health application (Digitale Gesundheitsanwendungen, DiGA in German) guidelines, Mobile App Rating Scale (MARS), and other resources. A total of 18 apps were evaluated. The final score...

DE-Lemma: A Maximum-Entropy Based Lemmatizer for German Medical Text
This study demonstrates a Machine Learning approach for training Apache OpenNLP-based lemmatizer models from publicly available German treebanks. The resulting four "DE-Lemma" models were evaluated against a sample of (bio)medical nouns, randomly selected from real-world discharge letters. The most promising DE-Lemma model achieved an accuracy of 88.0% (F1 = .936).PMID:37697853 | DOI:10.3233/SHTI230712

Concept Graphs: A Novel Approach for Textual Analysis of Medical Documents
Stud Health Technol Inform. 2023 Sep 12;307:172-179. doi: 10.3233/SHTI230710.ABSTRACTThe task of automatically analyzing the textual content of documents faces a number of challenges in general but even more so when dealing with the medical domain. Here, we can't normally rely on specifically pre-trained NLP models or even, due to data privacy reasons, (massive) amounts of training material to generate said models. We, therefore, propose a method that utilizes general-purpose basic text analysis components and state-of-the-art transformer models to represent a corpus of documents as multiple graphs, wherein important conce...

Pitfalls in Analyzing FHIR Data from Different University Hospitals
Stud Health Technol Inform. 2023 Sep 12;307:146-151. doi: 10.3233/SHTI230706.ABSTRACTThe German Medical Informatics Initiative has agreed on a HL7 FHIR-based core data set as the common data model that all 37 university hospitals use for their patient's data. These data are stored locally at the site but are centrally queryable for researchers and accessible upon request. This infrastructure is currently under construction, and its functionality is being tested by so-called Projectathons. In the 6th Projectathon, a clinical hypothesis was formulated, executed in a multicenter scenario, and its results were analyzed. A numb...

Clustering on Player Types of Students in Health Science - Trial and Data Analyses
Stud Health Technol Inform. 2023 Sep 12;307:89-95. doi: 10.3233/SHTI230698.ABSTRACTGamification has many positive effects, such as increased motivation, engagement, and well-being of users. For this purpose, a wide field of game mechanics is already available that can be used in teaching. For the development of gamified teaching methods, it's important to adapt the mechanics used to the students. There are different models that divide target groups of games and gamification into player types to understand what motivates the respective users. This paper describes a study of player types among students of health-related disc...

Modelling Adverse Events with the TOP Phenotyping Framework
Stud Health Technol Inform. 2023 Sep 12;307:69-77. doi: 10.3233/SHTI230695.ABSTRACTThe detection and prevention of medication-related health risks, such as medication-associated adverse events (AEs), is a major challenge in patient care. A systematic review on the incidence and nature of in-hospital AEs found that 9.2% of hospitalised patients suffer an AE, and approximately 43% of these AEs are considered to be preventable. Adverse events can be identified using algorithms that operate on electronic medical records (EMRs) and research databases. Such algorithms normally consist of structured filter criteria and rules to i...

How to Make Outpatient Healthcare Data in Germany Available for Research in the Dynamic Course of Digital Transformation
CONCLUSION: Considering the compared dimensions of architectural routes to access health data for secondary research use we conclude that data extraction from practice information systems is currently the most promising way due to data availability on a mid-term perspective. Integration of routine data into the national research data infrastructures might be enforced by convergence of to date different information models.PMID:37697833 | DOI:10.3233/SHTI230688
