Background:
Novel rosacea treatments are needed. Assessment methodologies for clinical trials of rosacea treatments are not standardized and are relatively inadequate. To determine the efficacy of new treatments, a valid and reliable assessment methodology is needed.
Objective:
We sought to determine the assessment methodologies used in clinical trials for rosacea treatments, to demonstrate the need for a valid and reliable assessment tool, and to describe the relevant properties of such a tool.
Methods:
PubMed and MEDLINE were searched for clinical trials of rosacea treatments since January 1, 1985.
Results:
In all, 32 clinical trials met inclusion criteria. Assessment methodologies were highly variable, and standardized assessment methodologies were used in only 3 studies. The various manifestations of rosacea were assessed inconsistently.
Limitations:
Eighteen articles could not be included as a result of lack of access to the full text.
Conclusions:
The diverse methodologies make the assessment of novel treatments and comparison of treatments difficult. A valid and reliable assessment tool is needed to properly assess novel treatments to improve the management of rosacea.
Insights
Standardized assessment methods for rosacea clinical trials are lacking. Developing a valid and reliable tool is crucial for evaluating new rosacea treatments and improving patient management.
Area of Science:
- Dermatology
- Clinical Trials Methodology
Background:
- Novel rosacea treatments require robust efficacy assessment.
- Current clinical trial methodologies for rosacea are inconsistent and inadequate.
- A standardized, valid, and reliable assessment tool is needed for rosacea research.
Purpose of the Study:
- To review assessment methodologies in rosacea treatment clinical trials.
- To highlight the need for a validated rosacea assessment tool.
- To outline desirable properties for a new assessment instrument.
Main Methods:
- Systematic literature search of PubMed and MEDLINE databases.
- Inclusion of clinical trials for rosacea treatments published since January 1, 1985.
- Analysis of assessment methodologies employed in selected trials.
Main Results:
- 32 clinical trials met the inclusion criteria.
- Significant variability in assessment methodologies was observed.
- Only 3 studies utilized standardized assessment approaches.
- Inconsistent assessment of diverse rosacea manifestations.
Conclusions:
- Methodological diversity hinders effective novel treatment evaluation and comparison.
- A validated and reliable assessment tool is essential for advancing rosacea management.
- Improved assessment tools will facilitate better understanding and treatment of rosacea.
