Summary

A decision-analysis model objectively reviewed third-generation cephalosporins, leading to formulary changes. Ceftazidime and ceftriaxone replaced older agents, promoting rational drug use and cost savings.

Area of Science:

  • Pharmacoeconomics
  • Clinical Pharmacy
  • Health Outcomes Research

Background:

  • Formulary review processes are critical for optimizing drug selection and resource allocation.
  • Third-generation cephalosporins represent a significant class of antibiotics with varying clinical and economic profiles.
  • Traditional formulary review methods may lack objectivity and structured decision-making.

Purpose of the Study:

  • To describe a structured, objective approach to formulary review for third-generation cephalosporins.
  • To implement a decision-analysis model for evaluating and ranking antibiotic agents.
  • To guide pharmacy and therapeutics (P&T) committee decisions for formulary management.

Main Methods:

  • A decision-analysis model was developed and approved by the P&T committee.

  • Evaluation criteria for third-generation cephalosporins were defined with assigned priority weights.
  • Clinical data (spectrum, pharmacokinetics, adverse effects, stability) and financial data (acquisition cost, cost per day) were collected.
  • Ranking scores were calculated by integrating clinical and financial data, weighted by importance.
  • Total scores determined drug rankings for formulary inclusion.

    • Main Results:

    • The decision-analysis process objectively evaluated cefotaxime, cefoperazone, moxalactam, ceftazidime, and ceftriaxone.
    • Ceftazidime and ceftriaxone emerged as the highest-scoring agents based on the defined criteria.
    • The P&T committee recommended removing cefotaxime, cefoperazone, and moxalactam from the formulary.
    • Ceftazidime and ceftriaxone were recommended for inclusion, replacing the removed agents.

    Conclusions:

    • The structured decision-analysis model provides an objective framework for formulary review.
    • This approach facilitated the rational selection of third-generation cephalosporins, favoring ceftazidime and ceftriaxone.
    • Implementing such a model can lead to improved drug therapy and potential cost savings for healthcare institutions.
    • Variations in criteria weighting may yield different formulary recommendations at other institutions.
