Electronic Patient Care System for Medication Error Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for providing patient care, particularly in hospitals, face challenges in efficiently ordering and administering medications due to issues like miscommunication, user errors, and inefficiencies in medication preparation and delivery, despite the use of electronic medical records and computerized provider order entry systems.
Innovation Solution
An electronic patient care system comprising a monitoring client and an order-input module that gathers patient data, compares it with pre-existing information, and provides warnings or alerts for medication administration, while also interacting with patient-care devices like infusion pumps to ensure accurate treatment delivery through a hub that controls access to hardware and software resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual medication ordering and administration processes are used, then flexibility in medication delivery is maintained, but user errors and miscommunication increase
Solution Approach 1:
The patent introduces an electronic intermediary system that acts as a mediator between the provider, pharmacist, and nursing staff. This system includes a server that receives medication orders, a pharmacist workstation for verification, and a nursing workstation for administration. The intermediary electronic system reduces human error and miscommunication while maintaining the collaborative workflow among multiple healthcare professionals.
2Loss of information
If electronic medical records and computerized provider order entry systems are implemented, then information accuracy improves, but system complexity and user interface challenges increase
Solution Approach 1:
The patent segments the medication management system into distinct functional modules: a provider workstation for ordering, a pharmacist workstation for verification and preparation instructions, a nursing workstation for administration, and a server for coordinating communications. Each module has a specialized interface tailored to its specific function, reducing the complexity burden on individual users while maintaining comprehensive information accuracy across the entire system.
Solution Approach 2:
The server component provides universal functionality by serving multiple workstations with different requirements. It routes information appropriately to each module, manages communication protocols, and maintains the central medication order database. This multi-functional server reduces overall system complexity by providing a single coordinating platform rather than requiring separate systems for each function.
3Reliability
If automated medication monitoring is implemented, then medication errors are reduced, but the extent of automation and system resources required increase
Solution Approach 1:
The system implements feedback loops at multiple stages: the pharmacist verifies the medication order against the patient's electronic medical record and provides feedback on appropriateness; the system tracks medication preparation status and provides feedback to the nursing station; and the administration time is recorded and fed back to verify timely delivery. This structured feedback mechanism reduces errors while maintaining appropriate human involvement.
Solution Approach 2:
The pharmacist performs preliminary verification of the medication order before it reaches the administration stage. The system automatically checks for drug interactions, allergies, and dosing appropriateness before the nurse receives the medication. This preliminary automated checking reduces errors early in the process while minimizing the automation burden at later stages.

AI summary
A method, related system and apparatus are disclosed. The method is implemented by an operative set of processor executable instructions configured for execution by a processor. The method includes the acts of: determining if a monitoring client is connected to a base through a physical connection; establishing a first communications link between the monitoring client and the base through the physical connection; updating, if necessary, the interface program on the monitoring client and the base through the first communications link; establishing a second communications link between the monitoring client and the base using the first communications link; and communicating data from the base to the monitoring client using the second communications link.
