Summary
A new web-based tool, PROSER, assists pathologists with peripheral blood smear (PBS) interpretation. This clinical decision support (CDS) system was well-received by residents in a quality improvement study.
Area of Science:
- Pathology
- Medical Informatics
Background:
- Peripheral blood smear (PBS) interpretation is crucial for pathology practice and training.
- Traditional PBS interpretation methods have seen little innovation for decades.
Purpose of the Study:
- To describe a novel web-based clinical decision support (CDS) tool, PROSER, designed to aid pathologists in peripheral blood smear (PBS) interpretation.
Main Methods:
- A mixed-methods quality improvement study deployed PROSER in an academic hospital over two months.
- PROSER integrated with EHR and data warehouse for patient data, using rule-based logic to draft interpretations based on morphologic findings.
- User perceptions were assessed via a Likert-type survey.
Main Results:
- PROSER processed numerous lab values and microscopy findings, generating automated reports from a library of phrases.
- The system was positively received by pathology residents.
Conclusions:
- A web-based CDS tool for PBS interpretation was successfully deployed.
- Further research is required to quantify the impact of this intervention on clinical outcomes and resident education.

Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...
