A microcomputer system for the identification of drug interactions

Area of Science:

• Critical Care Medicine
• Clinical Pharmacy
• Health Informatics

Background:

• Critically ill patients require complex drug regimens, often involving multiple specialists.
• Rapid changes in patient condition necessitate frequent therapy alterations.
• Lack of specialized knowledge in adverse drug interactions among some consultants can lead to risks.

Purpose of the Study:

• To develop and describe a microcomputer-based system for screening potential drug contraindications.
• To enable timely identification of adverse drug interactions before drug administration.
• To improve medication safety in intensive care settings.

Main Methods:

• A FORTRAN-written software package was developed for storing and retrieving drug interaction data.
• The system was designed to assess up to 18 drugs concurrently.
• A database was created including 102 Intensive Therapy Unit stock drugs and 25 additional interacting drugs.

Main Results:

• The system can screen for adverse drug interactions, differentiating between therapeutic and chemical/physical incompatibilities.
• It assesses potential interactions that could lead to serious or fatal consequences.
• The software facilitates pre-administration screening, addressing a critical gap in current practice.

Conclusions:

• Microcomputer-based drug interaction screening is feasible and beneficial for critically ill patients.
• This system can enhance medication safety by preventing adverse drug events.
• Implementing such a system can support clinical decision-making in intensive care units.
