Dosage Verification System Using Age-Weight Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medication errors due to incorrect dosages, particularly in pediatric patients, pose a significant risk of preventable deaths and injuries, as healthcare providers often fail to adjust dosages based on patient weight, body size, or body surface area, leading to dangerous or fatal consequences.
Innovation Solution
A computer-implemented method and system for verifying dosages in healthcare transactions, which determines a patient's age and probable weight to assess whether a prescribed dosage is appropriate, utilizing age-weight correlation charts or lookup tables, and compares it to expected dosages to identify potential errors before product dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If healthcare providers prescribe dosages without verifying patient weight and body size, then the prescribing process is simple and quick, but medication errors occur leading to dangerous or fatal consequences
Solution Approach 1:
The patent introduces an intermediary verification system that acts as a mediator between the prescriber and the patient. This system receives prescription data, automatically determines patient weight from stored records, calculates appropriate dosages using reference standards, and provides verification feedback. The intermediary nature of this system resolves the contradiction by handling the complex verification tasks automatically, allowing prescribers to maintain simple prescribing workflows while ensuring accurate dosages through the background verification process.
Solution Approach 2:
The verification system performs self-service by automatically retrieving patient weight information from stored databases, calculating appropriate dosages using embedded reference standards, and generating verification results without requiring manual intervention. This self-service capability eliminates the need for prescribers to manually verify weight and dosage calculations, thereby maintaining workflow simplicity while ensuring dosage accuracy through automated calculations and comparisons.
2Reliability
If healthcare providers manually verify dosages based on patient weight, then dosage accuracy improves, but the time required for prescribing increases
Solution Approach 1:
The system performs preliminary actions by pre-storing patient weight information in databases and pre-calculating appropriate dosages based on reference standards before the actual prescribing occurs. When a prescription is submitted, the system quickly retrieves pre-stored weight data and performs automated dosage calculations, eliminating the need for time-consuming manual measurements and calculations during the prescribing moment. This preliminary preparation resolves the contradiction by ensuring dosage accuracy through pre-computed values while maintaining rapid prescribing throughput.
Solution Approach 2:
The patent replaces manual mechanical processes of weight measurement and dosage calculation with automated electronic systems. Computer algorithms automatically retrieve weight data, perform mathematical calculations based on reference standards, and generate verification results, substituting the time-consuming manual mechanical processes with rapid electronic computation. This substitution resolves the contradiction by maintaining high dosage accuracy through systematic verification while reducing prescribing time through automated processing.
3Reliability
If dosage verification systems are implemented, then medication errors are reduced, but the complexity of healthcare transactions increases
Solution Approach 1:
The patent extracts the complex dosage verification logic into a separate, dedicated verification system that operates independently from the core prescribing workflow. The verification system handles weight retrieval, dosage calculation, and reference standard comparison as distinct extracted functions, allowing the main prescribing system to remain simple while the extraction of verification complexity to a specialized subsystem ensures dosage safety without burdening the overall transaction processing with unnecessary complexity.
Solution Approach 2:
The verification system is designed with universal functionality to handle multiple verification tasks through a single integrated process. It simultaneously performs weight verification, dosage calculation, reference standard comparison, and error detection in one unified verification routine, rather than requiring separate systems for each function. This multi-functionality resolves the contradiction by ensuring comprehensive dosage safety through a single universal verification mechanism that does not multiply system complexity.

AI summary
Systems and methods are provided for verifying dosages associated with healthcare transactions. A healthcare transaction may be received from a healthcare provider computer. The received healthcare transaction may include information associated with a patient and a prescribed product. Based at least in part on the received information, an age of the patient may be determined. Based upon the determined age, a probable weight for the patient may be determined. The probable weight may be utilized to determine whether a prescribed dosage for the product is an appropriate dosage for the patient.
