Methotrexate: improving safety profile
1Department Dermatology, Churchill Hospital, Oxford, UK. nandcgrills@optusnet.com.au
Abstract:
Over the past 10 years, there have been 137 patient safety incidents in England associated with methotrexate prescribing. Recent reports show that Australia has similar concerns. Using the valuable tool of an audit, we reviewed our departmental prescribing practices for 49 patients with psoriasis on methotrexate. Results highlighted poor documentation that patients were receiving appropriate information sheets detailing complications of the drug. Inconsistencies between prescribers were also noted, particularly in regards to haematological monitoring. A review of the current published work and the guidelines of other leading centres was performed and consistent, evidence-based guidelines were produced for the department. Such guidelines are essential in order to minimize the recognized complications of methotrexate. Recent studies highlight procollagen peptide III as a valuable adjunct for monitoring hepatotoxicity, while there is no longer a significant role for routine recording of cumulative dose. It would be valuable to repeat the audit to ensure a change in practice and an improved adherence to common guidelines.
Insights
Methotrexate prescribing has led to patient safety incidents. An audit revealed poor documentation and inconsistent monitoring, prompting the development of new evidence-based guidelines to minimize drug complications.
Area of Science:
- Dermatology
- Pharmacology
- Patient Safety
Background:
- Methotrexate is a common treatment for psoriasis.
- Patient safety incidents linked to methotrexate prescribing are a growing concern globally.
- Previous audits indicate issues with methotrexate prescribing practices.
Purpose of the Study:
- To audit current methotrexate prescribing practices for psoriasis patients within the department.
- To identify areas for improvement in patient information and monitoring.
- To develop evidence-based guidelines to enhance patient safety.
Main Methods:
- Retrospective audit of 49 psoriasis patients on methotrexate.
- Review of departmental prescribing practices and documentation.
- Literature review of current evidence and guidelines from leading centers.
Main Results:
- Inadequate documentation regarding patient information on methotrexate complications.
- Inconsistencies in prescribing practices, particularly concerning hematological monitoring.
- Identification of procollagen peptide III as a useful marker for monitoring liver toxicity.
Conclusions:
- Development of consistent, evidence-based guidelines is crucial for minimizing methotrexate complications.
- Updated guidelines should incorporate newer monitoring methods like procollagen peptide III.
- Further audits are recommended to ensure adherence to new guidelines and improve patient safety.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
