Medical Order Entry Interface for Duplicate Order Detection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing medical order systems fail to effectively minimize duplicate and similar entries due to the ineffectiveness of pop-up windows, which are often ignored by medical personnel, leading to increased duplicative order errors and inefficiencies.

Innovation Solution

A medical records computer system that includes a processor to compare new medical orders with existing orders, highlighting similar or duplicate entries on the display through visual cues such as font changes, color highlights, or enclosing orders within lines or boxes, and categorizing orders by type to facilitate quick analysis and prevention of similar entries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pop-up windows are used to notify medical practitioners of duplicate orders, then duplicate order entry can be reduced, but the system becomes ineffective because practitioners ignore or disable the warnings

Engineering Contradiction:

Improveeffectiveness of duplicate order preventionVSAvoiduser interaction with warning system

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of using traditional pop-up windows that interrupt the workflow, the system inverts the approach by providing warnings directly within the order entry interface itself. The warning is displayed in the same window where the practitioner is entering the order, making it an integral part of the entry process rather than a separate interruption. This eliminates the need for practitioners to switch between windows and ensures the warning is immediately visible and cannot be easily dismissed.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The system introduces an intermediary layer between the order entry process and the warning notification. Rather than using a separate pop-up window that requires user action to dismiss, the warning is mediated through the existing order entry interface, where it is automatically displayed and cannot be disabled. This intermediary approach ensures the warning is both visible and actionable without requiring additional user interaction.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If computerized provider order entry is implemented, then efficiency and data verification are improved, but duplicate order errors increase due to ease of entry

Engineering Contradiction:

Improvehealth care efficiencyVSAvoidaccuracy of medical orders

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system implements real-time feedback by automatically comparing new order entries against existing patient orders and providing immediate warnings when duplicate or similar orders are detected. This feedback loop operates continuously during the order entry process, allowing practitioners to see the potential duplication before finalizing the order. The feedback is integrated into the order entry interface, ensuring it is immediately visible and actionable.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary comparison of the new order against existing orders before the order is finalized. By conducting this comparison in advance and providing warnings before the order is submitted, the system prevents duplicate entries from being processed. This preliminary action allows practitioners to review and correct potential errors before they impact patient care.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If real-time comparison of orders is performed, then duplicate entry is minimized, but system complexity increases

Engineering Contradiction:

Improveminimization of duplicate ordersVSAvoidcomputer system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses the existing computerized provider order entry software and infrastructure to perform the duplicate detection function. Rather than adding a separate complex system, the existing software is enhanced to include comparison capabilities that utilize its current processing power and database access. This multi-functional approach allows the same system to handle both order entry and duplicate detection without requiring additional specialized hardware or complex separate systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An electronic medical records system with computerized provider order entry includes error checking for duplicate or medically similar orders. In the system, similar medical orders are displayed on adjacent screens and are highlighted, thereby allowing medical personnel to easily identify and evaluate the orders. The user can therefore choose to modify or delete medically similar entries easily and quickly, thereby minimizing the occurrence of duplicate or repetitive orders, and increasing efficiency of the system.
