Abstract:
The objective of most phase III, randomized controlled clinical trials with antimicrobials is to obtain approval by the regulatory agencies for a specific indication. However, the real clinical utility of these trials is limited because the patients included are usually at low risk of infection caused by antibiotic-resistant or difficult-to-treat microorganisms, and the conditions in which the studies are performed differ from those in real life. Therefore, observational studies are an essential complement. Once a new antibiotic has been commercialized, the post-registry follow-up phase begins. The EUCORE registry is a European multicenter, retrospective, non-comparative post-authorization study that included patients receiving at least one dose of daptomycin. Despite their limitations, these types of study provide useful information that should be thoroughly analyzed and interpreted.
Insights
Phase III antimicrobial trials have limited real-world utility due to patient selection. Post-authorization studies, like the EUCORE registry for daptomycin, offer crucial insights into antibiotic effectiveness in actual clinical settings.
Area of Science:
- Infectious Diseases
- Clinical Pharmacology
- Health Services Research
Context:
- Phase III randomized controlled trials (RCTs) for antimicrobials primarily aim for regulatory approval.
- These RCTs often include low-risk patients, limiting generalizability to real-world infections, especially those involving antibiotic-resistant bacteria.
- The controlled environment of RCTs may not reflect actual clinical practice, necessitating complementary study designs.
Purpose:
- To evaluate the utility of post-authorization studies as a complement to traditional clinical trials for antimicrobials.
- To analyze data from the EUCORE registry, a European multicenter, retrospective, non-comparative study of daptomycin use.
- To highlight the importance of interpreting real-world data from observational studies despite their inherent limitations.
Summary:
- The EUCORE registry collected data on patients receiving daptomycin, offering real-world insights post-commercialization.
- This retrospective, non-comparative study complements findings from phase III trials by examining antibiotic use in a broader patient population.
- The study underscores the value of analyzing observational data to understand antimicrobial effectiveness and challenges in clinical practice.
Impact:
- Provides valuable real-world data on daptomycin use, supplementing evidence from controlled trials.
- Informs clinical decision-making and antibiotic stewardship by offering insights into actual treatment outcomes.
- Highlights the necessity of robust post-authorization surveillance for understanding the long-term clinical utility of new antimicrobial agents.

Study Designs in Epidemiology
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.

Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care evaluation by...
Nursing Clinical Information System
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:
