Operational Processes

Effective P&T Committees operate through established processes and procedures:

Regular Meetings

Most committees meet monthly, though the frequency may vary based on institutional needs. Meetings follow structured agendas, with materials distributed in advance to allow members adequate preparation time.

Subcommittees

Many institutions utilize subcommittees to efficiently manage specific therapeutic areas or functions:

• Antimicrobial Subcommittee
• Oncology Subcommittee
• Medication Safety Subcommittee
• Pharmacoeconomics Subcommittee
• Therapeutic Class Review Subcommittees

Drug Formulary Management

The formulary serves as the foundation for the P&T Committee's work and represents a dynamic system requiring continuous maintenance and evaluation. Efficient formulary management balances clinical excellence with fiscal responsibility through evidence-based decision-making.

Formulary Development

Formulary development follows a systematic approach:

1. Identification of therapeutic needs
2. Critical evaluation of available therapies based on scientific evidence
3. Consideration of patient populations within the institution
4. Evaluation of clinical outcomes and safety profiles
5. Assessment of acquisition costs and total cost of care
6. Selection of preferred agents within therapeutic classes

Formulary Maintenance

Ongoing maintenance ensures the formulary continues to meet patient needs efficiently:

• Monthly review of new drug applications
• Regular therapeutic class evaluations
• Monitoring of product shortages and availability
• Response to safety alerts and black box warnings
• Annual formulary revision
• Review of non-formulary utilization patterns

Medication Use Evaluation

Medication Use Evaluation (MUE) is a quality improvement activity that the P&T Committee utilizes to monitor medication use outcomes. This systematic process involves:

Selection Criteria

P&T Committees prioritize medications for MUE based on:

• High-risk medications
• High-cost medications
• Medications with potential for misuse or adverse effects
• Medications frequently used off-label
• Drugs with narrow therapeutic windows
• Newly added formulary medications

Evaluation Process

The MUE process typically follows these steps:

1. Development of criteria for appropriate use
2. Retrospective or prospective data collection
3. Data analysis against predetermined criteria
4. Identification of practice variations
5. Development of interventions for improvement
6. Implementation of corrective actions
7. Follow-up evaluation to measure impact

Impact on Quality Improvement

Through MUE activities, P&T Committees drive quality improvement initiatives that directly enhance patient care. These evaluations identify opportunities for improvement, guide educational interventions, and inform policy decisions, ultimately promoting safe and effective medication therapy.
