Solution Overview

Problem

Hospital nurses often lack timely access to critical lab values when dispensing medications, leading to potential harm to patients due to delayed updates on treatment changes.

Innovation Solution

A system that uses automated dispensing machines (ADMs) connected to a server and clinical information databases to provide real-time alerts to nurses about medication dispense changes based on the most recent lab values, ensuring up-to-date information is available during dispensing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If nurses manually retrieve medications from ADM without real-time lab value integration, then the dispensing process remains simple and quick, but nurses lack timely access to critical lab values leading to delayed treatment change information

Engineering Contradiction:
Improvetimely access to critical lab valuesVSAvoidsystem complexity for providing real-time alerts
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system implements feedback by automatically querying the lab database for critical values when a nurse initiates a medication dispense transaction at the ADM. The server receives the dispense request, retrieves relevant lab values, and presents them to the nurse through the ADM interface, ensuring timely information delivery without manual intervention

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The server acts as an intermediary between the ADM and the lab database. When the ADM requests medication dispense information, the server mediates by querying the lab database for critical values and integrating this information into the dispense transaction data returned to the ADM, eliminating the need for direct complex connections between ADM and database

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the system queries lab database for every medication dispense request, then nurses receive up-to-date critical lab values, but system response time and processing load increase

Engineering Contradiction:
Improveaccuracy of medication dispensing decisionsVSAvoidtime delay in medication dispense transaction
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial action by querying the lab database selectively rather than for every dispense request. The server determines whether a lab value query is necessary based on the specific medication and patient context, querying only when critical values are likely to impact the dispense decision, thus reducing unnecessary database access and processing time

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary action by pre-fetching and caching lab values that are likely to be needed for upcoming dispense transactions. The server can proactively retrieve critical lab values before they are actually requested, storing them temporarily to avoid redundant database queries when dispense requests are made

Inventive Principle:
Principle #10Preliminary action

AI summary

According to certain embodiments of the present disclosure, a system for providing medication dispense alert notifications is described. The system includes a communications module configured to receive, from a client, a request for information regarding a medication dispense for a patient, and to obtain clinical information associated with the patient based on the request. The system also includes a processor configured to determine, based on the clinical information, whether a response to be provided to the client will include an alert regarding the medication dispense. The communications module is further configured to provide, to the client, the response to the request. Methods and machine-readable media are also described.
