ABSTRACT
Objectives: This is a retrospective study that set out to assess the safety, feasibility and cost savings of temporary relaxed blood test monitoring for patients on MTX under the rheumatology service that was rolled out during the coronavirus pandemic. Methods: This is a single-centre study that reviewed the blood tests of all patients who received an MTX prescription from the trust between December 2019 and November 2020. After the application of inclusion and exclusion criteria, the blood testing intervals and findings were analysed and collated. The cost of the blood tests was obtained from the laboratory. Results: A total of 1194 patients were identified as having received an MTX prescription. After applying inclusion and exclusion criteria, 462 patients were included. Of these, 395 (85%) patients had a blood test within the standard 3-month schedule and 67 had blood tests within the relaxed blood monitoring schedule. Six patients had an abnormality identified on their blood tests, but no harm was caused by any of these abnormalities. The intervention resulted in a cost savings of at least £1187 from the blood test costs alone. Conclusion: MTX is a widely used steroid-sparing agent that requires regular blood test monitoring to reduce adverse outcomes for patients. During extraordinary circumstances such as a pandemic, relaxing the interval between monitoring blood tests in stable patients is a feasible intervention. A relaxed monitoring blood test interval for a set period is safe, achievable and cost effective.
