Objectives National and international guidelines recommend prompt referral of patients presenting with inflammatory arthritis (IA), but general practitioners (GPs) feel uncertain in their proficiency to detect synovitis through joint examination, the method of choice to identify IA. Our objective was to develop and validate a rule composed of clinical characteristics to assist GPs and other physicians in identifying IA when in doubt. Design Split-sample derivation and validation study. Setting… 

The value of inquiring about functional impairments for early identification of inflammatory arthritis: a large cross-sectional derivation and validation study from the Netherlands

Patient-reported difficulties with dressing in patients with suspected IA associated with actual IA presence could be of help in future early IA detection tools for healthcare professionals with limited experience in joint examination.

Realising early recognition of arthritis in times of increased telemedicine: the value of patient-reported swollen joints

It is suggested that evaluation of patientreported swelling is less valuable for early detection of IA than for flare detection in patients with established RA, and evidencebased care in the era of telemedicine will continue to be important.

Barriers to the Diagnosis of Early Inflammatory Arthritis: A Literature Review

This non-systematic comprehensive review will describe the main barriers in the identification of patients with inflammatory arthritis at different levels and the different strategies that have been implemented with the objective to overcome the recognized barriers and their impact in the reduction of delays.

Delayed diagnosis and treatment of rheumatoid arthritis in Sarawak General Hospital.

The delays in the diagnosis of rheumatoid arthritis were mainly from the patient and primary care, and the median time from symptom onset to DMARDS initiation was 23.5 weeks.

Impact of triage by a rheumatologist on appropriateness of referrals from primary to secondary care: a cluster randomized trial.

Triage by a rheumatologist in primary care provides appropriate care and adequate experience of care, leading to a higher quality of life, and long-term evidence is needed to assess the value on cost-effectiveness before implementing this strategy nationwide.

A Study Protocol on the Evaluation of Referral Strategies for Inflammatory Arthritis in Primary Care Patients at the Level of Healthcare Organization, Patient Relevant Outcomes and Costs

There is sufficient supporting evidence to implement one of the referral strategies as a standard of care, and with these optimization strategies a higher quality of care can be achieved, that might be of value for all patients with arthralgia.

Added value of multiple autoantibody testing for predicting progression to inflammatory arthritis in at-risk individuals

Adding value of multiple AutoAbs testing for identifying progressors to clinical disease, allowing more specific stratification for intervention studies is confirmed.

Diagnostic Performance and Clinical Utility of Referral Rules to Identify Primary Care Patients at Risk of an Inflammatory Rheumatic Disease

To determine the diagnostic performance and clinical utility of the Rotterdam Early Arthritis Cohort (REACH) and the Clinical Arthritis Rule (CARE) referral rules in an independent population of

Barriers and facilitators for implementation of a digital referral algorithm for inflammatory arthritis - a qualitative assessment in patients and caregivers

Successful implementation of a digital referral algorithm needs a systematic multi-facetted approach, considering the barriers and facilitators for implementation as discussed.


US scores were able to detect therapeutic response to TCZ plus MTX earlier than clinical scores and may therefore be a promising imaging biomarker in managing RA.

A systematic literature review of strategies promoting early referral and reducing delays in the diagnosis and management of inflammatory arthritis

A co-ordinated effort will be required by the rheumatology and primary care community to address delays to care for patients with inflammatory arthritis effectively.

Early referral recommendation for newly diagnosed rheumatoid arthritis: evidence based development of a clinical guide

Clinical evidence strongly supports the observations that structural damage occurs early in active RA and that early DMARD treatment improves the long term outcome of the disease.

Improved early identification of arthritis: evaluating the efficacy of Early Arthritis Recognition Clinics

The EARC increased the early identification of arthritis and RA and also reduced delay of GPs in identifying early arthritis patients.

How do general practitioners identify inflammatory arthritis? A cohort analysis of Dutch general practitioner electronic medical records.

GPs mainly used classical signs of inflammation to diagnose inflammatory arthritis, while other items that are regularly assessed in secondary care (morning stiffness, squeeze-test, family history) were infrequently recorded by GPs.

Delays in assessment of patients with rheumatoid arthritis: variations across Europe

The contribution of patients, professionals and health systems to treatment delay for patients with RA in Europe is highlighted, and interventions are required in all centres to ensure timely treatment for patients.

Diagnosis, prognosis and classification of early arthritis: results of a systematic review informing the 2016 update of the EULAR recommendations for the management of early arthritis

This SLR highlights the importance of early referral for patients with EA and confirms that RF and mainly ACPAs as well as a search for structural X-rays changes may help in the diagnosis and prognosis of patients withEA.

A parallel group cohort to determine the measurement properties of an early inflammatory arthritis detection tool.

The tool has favourable measurement and discriminative properties and the rheumatology triage scoring algorithm was externally validated.

What is the evidence for the presence of a therapeutic window of opportunity in rheumatoid arthritis? A systematic literature review

Even when heterogeneity of patients is taken into account, prolonged symptom duration is associated with radiographic progression and a lower chance on DMARD-free sustained remission and these data may support the presence of a ‘window of opportunity’.

Long-term impact of delay in assessment of patients with early arthritis.

Assessment in <12 weeks is associated with less joint destruction and a higher chance of achieving DMARD-free remission as compared with a longer delay in assessment, implying that attempts to diminish the delay in seeing a rheumatologist will improve disease outcome in patients with RA.

Development of a self-administered early inflammatory arthritis detection tool

An eleven-question, EIA detection tool suitable for self-administration was developed to screen subjects with six to 52 weeks of musculoskeletal complaints and Psychometric and performance property testing of the tool is ongoing.
