Troubleshooting
Objective
To assess real-world trajectories of glucocorticoid-therapy initiated as part of early rheumatoid arthritis (RA) treatment.
Eligibility
Observational cohort studies (CS) published between Jan 01, 2005 and now. Studies must enroll early (or methotrexate-naive) RA patients and report on those starting/taking systemic glucocorticoids (GCs) at baseline and describe at least one of our outcomes at two time points minimum.
Data Source
MEDLINE (via PubMed).
Search Strings
Search strings were developed utilizing the PICOS mnemonic:

Population: early (or methotrexate-naïve) RA - Intervention: systemic GCs - Comparator: any - Outcome: any - Study design: observational cohort study
(Rheumatoid[Title] OR Arthritis, Rheumatoid[MeSh:NoExp])
AND (early[title/abstract] OR naïve[title/abstract])
AND (Cortison*[title/abstract] OR Predniso*[title/abstract] OR Cortico*[title/abstract] OR Glucocort*[title/abstract] OR Steroid*[title/abstract] OR Glucocorticoids[MeSh:NoExp])
AND (Cohort[Title/Abstract] OR Longitudinal[Title/Abstract] OR Prospective[Title/Abstract] OR Registry[Title/Abstract] OR Longitudinal Studies[Mesh:NoExp] OR Cohort Studies[Mesh:NoExp] OR Registries[Mesh:NoExp])
AND 2005/01/01:2021/01/01[dp]
NOT (random*[Title] OR randomized controlled trial[pt])
NOT (review[Title] or review[pt])
Outcomes
Mean/median dose of prednisone equivalent, proportion of patients who could discontinue GCs, proportion of patients who could reduce GCs (all: at baseline, 3, 6, 9, 12, and 24 months).
Data Synthesis
Meta-analysis will be conducted to pool results, including meta-regression (mixed effects) to assess change over time for each outcome.
