Developing a minimum data set for cardiovascular Computerized Physician Order Entry (CPOE) and mapping the data set...

Area of Science:

• Health Informatics
• Medical Information Systems
• Cardiovascular Medicine

Background:

• Prescription errors are a significant cause of medical errors in cardiovascular patient care.
• Computerized Physician Order Entry (CPOE) systems can prevent prescription errors, but improper design and lack of user compliance are implementation barriers.
• A standard Minimum Data Set (MDS) is crucial for effective information system design, yet no study has defined an MDS for CPOE systems.

Purpose of the Study:

• To develop a Minimum Data Set (MDS) for cardiovascular Computerized Physician Order Entry (CPOE) systems.
• To standardize the developed MDS with Fast Healthcare Interoperability Resources (FHIR) for enhanced data interoperability.

Main Methods:

• A multi-method approach was employed, including a systematic review of CPOE data elements, analysis of medical records, expert panel validation, and physician surveys.
• Data elements were classified and mapped to FHIR resources to facilitate data sharing and integration with Electronic Health Record (EHR) systems.
• The process involved identifying, validating, and selecting necessary data elements, culminating in standardization with FHIR.

Main Results:

• A total of 109 essential data elements were identified for the cardiovascular CPOE MDS.
• The developed MDS was mapped to 5 core FHIR resources, with non-mapped elements incorporated as extensions.
• This study presents the first documented process for developing an MDS for cardiovascular CPOE.

Conclusions:

• The developed MDS for cardiovascular CPOE, standardized with FHIR, addresses data diversity and facilitates EHR integration.
• The methodology used in this study can serve as a model for creating MDS in other CPOE and health information systems.
• Standardizing CPOE data with FHIR is essential for improving data sharing and reducing errors in cardiovascular care.
