TLC-Act: A Novel Tool for Managing Drug Interactions

Area of Science:

• Pharmacology
• Clinical Pharmacy
• Health Informatics

Background:

• Clinical decision support systems (CDSS) are utilized by pharmacists for managing drug-drug interactions (DDIs).
• Existing research indicates potential suboptimal performance of current CDSS in delivering clinically relevant DDI information.
• There is a need for improved tools that better align with pharmacists' clinical assessment processes.

Purpose of the Study:

• To develop a novel DDI management tool that emulates a pharmacist's clinical thought process.
• To evaluate practitioners' perceptions and usability of the newly developed DDI management tool.

Main Methods:

• The study involved three phases: tool development, clinical implementation, and practitioner feedback collection.
• A comprehensive literature review and expert panel analysis informed the tool's design.
• The tool underwent simulation validation and was implemented in practice for six weeks, with feedback gathered via a qualitative survey from pharmacy residents.

Main Results:

• The developed tool, TLC-Act, incorporates key assessment components such as duration of use and patient-specific risk factors.
• Of the surveyed pharmacy residents, 73% found the TLC-Act tool slightly more useful for DDI assessment compared to using CDSS alone.
• The tool was implemented in clinical practice by hospital pharmacists and pharmacy residents.

Conclusions:

• The TLC-Act tool effectively maps the clinical thought process used by pharmacists in DDI assessment.
• This novel tool demonstrates potential for enhanced DDI management compared to CDSS alone by considering additional pertinent factors.
• The findings suggest TLC-Act could improve the practical application of DDI management in pharmacy practice.
