A Drug Information Center (DIC) is a specialized unit within a hospital or academic institution that provides accurate, unbiased, and evidence-based information about medications. It acts as a support system for healthcare professionals by offering reliable drug-related data needed for therapeutic decision-making. Establishing a Drug Information Center enhances patient safety, promotes rational drug use, and strengthens clinical pharmacy services.
Objectives of a Drug Information Center
- Provide up-to-date, evidence-based drug information to healthcare professionals.
- Support rational prescribing and safe medication practices.
- Assist in preventing medication errors and adverse drug reactions.
- Promote effective drug utilization evaluation and formulary management.
- Serve as a training and educational resource for students and staff.
- Contribute to research, pharmacovigilance, and policy-making.
Essential Steps in Establishing a Drug Information Center
1. Define Purpose and Scope
The first step in establishing a DIC is defining its objectives and the range of services it will provide. This may include answering drug information queries, participating in clinical rounds, reporting adverse drug reactions, or supporting hospital committees such as the Pharmacy and Therapeutics Committee (PTC).
2. Administrative Approval and Budget Planning
A DIC requires support from hospital administration. Budget planning should cover:
- Infrastructure and equipment
- Drug information resources and subscriptions
- Personnel salaries
- Software and database access
- Training and operational expenses
3. Physical Infrastructure Requirements
The Drug Information Center should be located in a quiet, easily accessible area within the pharmacy or hospital. Essential infrastructure includes:
- Workstations with computers
- Internet access and networking
- Telephone lines for receiving queries
- Furniture for staff and visitors
- Space for books, journals, and reference materials
4. Staffing and Personnel
A well-functioning DIC requires trained professionals with specialized skills in literature evaluation, pharmacology, and communication.
- Clinical Pharmacist or Drug Information Pharmacist – primary coordinator.
- Pharmacy Assistants – to support documentation and clerical work.
- Faculty or Clinical Experts – for supervision and consultation.
5. Resources and Reference Materials
A high-quality DIC must have access to reliable drug information sources, categorized into primary, secondary, and tertiary resources.
Tertiary Resources (Core References)
- Micromedex
- Lexicomp
- AHFS Drug Information
- Martindale: The Complete Drug Reference
- British National Formulary (BNF)
Secondary Resources
- PubMed/MEDLINE
- Embase
- Cochrane Library
Primary Resources
- Clinical trials
- Systematic reviews
- Case reports and scientific articles
Services Provided by a Drug Information Center
1. Responding to Drug Information Queries
The primary function of a DIC is to answer queries from physicians, nurses, pharmacists, and sometimes patients.
- Dose and administration
- Drug interactions
- Adverse drug reactions
- IV compatibility
- Pharmacokinetics and pharmacodynamics
- Selection of therapeutic alternatives
2. Providing Support for Hospital Committees
- Pharmacy and Therapeutics Committee: formulary decisions, drug policy development.
- Antibiotic Stewardship Committees: rational antimicrobial use.
- ADR Monitoring Centers: support for pharmacovigilance.
3. Developing Drug Information Bulletins and Newsletters
DICs regularly publish updates on new drugs, safety alerts, guidelines, and medication-use policies.
4. Conducting Education and Training Programs
The center acts as a teaching resource for Pharm.D students, interns, and healthcare professionals.
5. Supporting Research and Evidence-Based Practice
DIC staff assist with literature searches, protocol development, and clinical research evaluation.
Standard Operating Procedures (SOPs)
To maintain quality and consistency, a DIC should establish SOPs for:
- Receiving and documenting queries
- Clarifying and researching questions
- Evaluating and analyzing data
- Preparing and delivering responses
- Documentation and archiving
- Follow-up procedures
Documentation Systems
Proper documentation ensures accountability and continuity of information.
- Query forms
- Search strategies used
- References consulted
- Final responses provided
- Date, time, and personnel involved
Quality Assurance in a Drug Information Center
Quality assurance programs are essential to evaluate the performance of the DIC and improve its services.
- Periodic peer-review of responses
- Updating reference materials
- Staff training and competency assessment
- Feedback from users
Role of a Clinical Pharmacist in DIC
- Provide accurate and unbiased drug information.
- Critically evaluate literature before offering recommendations.
- Support therapeutic decision-making in clinical practice.
- Assist with pharmacovigilance and ADR reporting.
- Educate healthcare professionals and students.
