BACKGROUND: The acceptance and use of clinical decision support systems are often limited by insufficient contextual adaptation. OBJECTIVES: Identification of barriers to context assessment and requirements for an instrument to capture context factors. METHODS: A questionnaire-based survey investigated requirements for a context assessment instrument. RESULTS: Challenges in context assessment include insufficient knowledge of context factors and communication issues. Desired features are concise information and ease of use. CONCLUSION: An efficient instrument for capturing context factors is crucial to addressing gaps, improving communication, and fostering interdisciplinary collaboration in CDSS development.
