Bottom Line: Therefore, a digital patient care record is introduced to establish the foundation for integrating healthcare-related information.The time for traversing the results strongly depends on the number of documents.The underlying database structure is presented, the import process for extracting incoming reports is described and the export process for generating new outgoing standardized reports is briefly illustrated.

ABSTRACT

Background: For an optimal care of patients in home healthcare, it is essential to exchange healthcare-related information with other stakeholders. Unfortunately, paper-based documentation procedures as well as the heterogeneity between information systems inhibit a well-regulated communication. Therefore, a digital patient care record is introduced to establish the foundation for integrating healthcare-related information.

Methods: For the digital patient care record, suitable integration techniques are required that store data in a compact way and offer flexibility as well as robustness. For this purpose, a generic storage structure based on the entity-attribute-value (EAV) model is introduced. This storage structure fulfills the stated requirements and incoming information can be stored directly without any loss of data.

Evaluation results and discussions: First performance tests regarding the query response time are given in this paper. The tests measured the connection time, the query execution time, and the time for traversing the result set. The time for executing the query is lowest. The time for traversing the results strongly depends on the number of documents. A concept comparison to other integration techniques is also presented.

Conclusions: This approach offers flexibility concerning different standard types and the evolution in healthcare knowledge and processes. It also allows for highly sparse data to be stored in a compact way. The underlying database structure is presented, the import process for extracting incoming reports is described and the export process for generating new outgoing standardized reports is briefly illustrated.

The Main Concept of the Entity-Attribute-Value Model. The entity-attribute-value serves for storing the structure of the information along with the actual values. This model mainly consists of three relations: The relations Entity and Attribute contain information about entities and their attributes and the relation Value stores the actual values for occurring entity-attribute pairs.

Fig2: The Main Concept of the Entity-Attribute-Value Model. The entity-attribute-value serves for storing the structure of the information along with the actual values. This model mainly consists of three relations: The relations Entity and Attribute contain information about entities and their attributes and the relation Value stores the actual values for occurring entity-attribute pairs.

Mentions: The entity-attribute-value model comprises three basic relations (as shown in Figure 2): the actual data are stored in the relation value whereas the entities and the attributes are stored in the relations entity and attribute, respectively.Figure 2
