Solution Overview
Problem
Pharmacists face inefficiencies and variability in prescription verification processes, leading to high error rates and increased costs due to the lack of standardized systems for reviewing medical prescriptions, which affects patient safety and accuracy.
Innovation Solution
A decision support system utilizing AI-enhanced modules for prescription verification, including data validation, clinical safety checks, regulatory compliance, and pharmacy policies, to automate the precheck process and provide recommendations for clarification or edits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pharmacists perform manual prescription verification with current standard operating procedures, then they can review prescriptions, but the process is time-consuming and prone to errors due to disjointed tools and lack of standardization
Solution Approach 1:
The prescription verification process is divided into distinct modular components: data validation module, clinical safety check module, regulatory compliance module, and pharmacy policy module. Each module handles specific verification tasks independently, allowing parallel processing and reducing overall review time while maintaining comprehensive checking.
Solution Approach 2:
Manual pharmacist review is supplemented and enhanced by an automated decision support system that uses algorithms and AI to perform initial verification tasks. The system automatically validates data accuracy, checks clinical safety, verifies regulatory compliance, and flags exceptions requiring pharmacist attention, replacing time-consuming manual mechanics with automated electronic processes.
2Reliability
If pharmacists perform comprehensive manual review of all prescription aspects, then dispensing accuracy can be maintained, but operational costs increase due to the expensive verification step
Solution Approach 1:
The system performs complete verification only when exceptions are detected. For routine prescriptions that pass automated checks, the system provides expedited approval with minimal pharmacist intervention. The decision support system applies partial verification (automated checks) to all prescriptions and excessive verification (full manual review) only when needed, optimizing the balance between accuracy and cost.
Solution Approach 2:
The prescription verification system performs self-validation through automated data validation, clinical safety checks, regulatory compliance verification, and policy checking. The system independently identifies and flags exceptions, allowing pharmacists to focus only on complex cases that require human judgment, thereby reducing operational costs while maintaining accuracy.
3Adaptability or versatility
If pharmacists use personal preferences and discretionary judgment in prescription review, then individual clinical decisions can be made, but variability in decision-making increases and standardization is lost
Solution Approach 1:
The decision support system provides structured feedback to pharmacists by presenting verified data, identified exceptions, and relevant clinical information in a standardized format. The system learns from pharmacist decisions and adjusts its verification algorithms, creating a feedback loop that improves consistency over time while preserving the ability to handle unique clinical scenarios.
Solution Approach 2:
The system transforms unstructured prescription data into standardized parameters and categories that can be consistently evaluated. By converting diverse prescription formats and clinical scenarios into uniform data structures with defined verification criteria, the system enables consistent decision-making across different pharmacists and situations while maintaining adaptability through configurable parameters.
4Loss of information
If pharmacists perform data entry and transcription tasks, then prescription information can be captured, but errors occur between source script and system data
Solution Approach 1:
The system creates and maintains a digital copy of the prescription data directly from the source script through electronic interfaces, eliminating manual transcription. The data validation module continuously verifies that the digital copy matches the source information, automatically detecting and alerting discrepancies without requiring pharmacist re-entry, thus preserving data accuracy while improving efficiency.

AI summary
A Decision Support System for prescription verification may include software and/or hardware configured to supplement analysis and decision-making in the workflow of a pharmacist and/or take action regarding certain steps in the prescription fulfillment process. The Decision Support System may include a plurality of software modules each configured to provide information to a user for a particular review, evaluation, or check regarding the Prescription Verification process. One or more the software modules of the Decision Support System may use or be implemented as an artificial intelligence (AI) module or algorithm, e.g., one or more decision trees, predictive models, large language models (LLMs), RAG enhanced LLMs, or rules-based engines. Decision Support System is configured to check information regarding the patient receiving the medication, the provider prescribing the medication, and the medication itself to ensure data accuracy and to determine whether it is safe to dispense the medication to the patient.
