• Conditions: Arthralgia; Rheumatic Disease
• Interventions: Procedure: Referral strategies

• Registration Number: NCT03454438
• Lead Sponsor: Maasstad Hospital

Brief Summary

The aim of this cluster randomized controlled trial is to improve the number of effectively referred patients with IRD to the rheumatology outpatient clinic with either use of validated referral pro formas or triage of IRD by specialists in a primary care setting compared to usual care. In addition, the investigators want to provide tools for the general practitioner to recognise IRD and improve early referral of patients with IRD, and a cost-effectiveness analysis will be performed to evaluate the decreasing effect on health-care cost.

Detailed Description

Rationale: Currently, only 22% of all patients referred to the rheumatologist by primary care are diagnosed with an inflammatory rheumatic disease (IRD). Previous research has shown that structured referral sheets and community-based specialist service improve appropriateness of referrals.

Objective: The aim of this study is to improve the number of effectively referred patients with IRD to the rheumatology outpatient clinic with either use of validated referral pro formas or triage of IRD by specialists in a primary care setting compared to usual care. In addition, the investigators want to provide tools for the general practitioner to recognise IRD and improve early referral of patients with IRD, and a cost-effectiveness analysis will be performed to evaluate the decreasing effect on health-care cost.

Study design: Cluster randomized trial with randomization of general practitioner clinics.

Study population: Primary care patients of 18 years or older who are suspected of an IRD and considered by a GP for referral to a rheumatologist.

Intervention: One group of GPs will use a standardized referral strategy for IRD, another group will consist of triage by a rheumatologist in the local primary care clinic, the third group is usual care.

Main study parameters/endpoints: Percentage of patients diagnosed with an IRD by a rheumatologists after 12 months. In addition, cost effectiveness, quality of life, work participation and health care costs at baseline and after 12 months.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There is no additional risk to participating patients. Patients might benefit from early referral since the referral pro formas point out important aspects of IRD that are frequently overlooked. Patients will be requested to fill in three online questionnaires related to quality of life, work participation and socio-economic costs. There are no additional visits, physical examinations or other tests.

Appropriate referred defined as patient diagnosed with an inflammatory rheumatic disease (IRD) as assessed by a rheumatologist, with an IRD as final diagnosis.

Secondary Outcome Measures

Name	Time	Method
iMTA Medical Consumption Questionnaire	12 months	Collects information on non-disease specific health-care consumption.
Health-care costs	12 months	Amount of outpatient clinic visits (visits to medical specialist, supporting staff, other staff), diagnostics (laboratory analyses, imaging), therapy (medication, medical procedures, over the counter medication), general practitioner consultation, medication use prescribed by general practitioner.
EuroQoL Health questionnaire	12 months	The standard analysis for health-related quality of life in cost-effectiveness research, tool in determining Quality adjusted life years (QALYs).
iMTA Productivity Cost Questionnaire	12 months	Measurement of productivity loss and work participation.
