Clinical Trial Summary

A Diagnostic Clinic for Functional Somatic Disorders (FSD) has been set up at the outpatient diagnostic center at Regionshospitalet Silkeborg. The objective of the clinic is to support General Practitioners (GPs) by offering early stage diagnostic evaluation of whether a patient has an FSD or the symptoms were caused by another physical illness or mental disorder.

As a novelty in this project, Internal Medicine consultants examine the patients for FSD, after having received training in diagnosing FSD by FSD experts. By performing diagnostic evaluation for physical diseases and FSD simultaneously, the investigators believe that the new clinic shall be able to accelerate the establishment of a final diagnosis for these patients who would otherwise likely undergo a protracted diagnostic course involving sequential evaluations at various specialty clinics.

The DISTRESS trial is a pragmatic randomized clinical trial which aims to evaluate the Diagnostic Clinic for FSD in terms of clinical cost-effectiveness outcomes.

Clinical Trial Description

Functional Somatic Disorders (FSD) are conditions where patients present with characteristic patterns of physical symptoms, accompanied by impairment or disability. FSD is a clinical diagnosis for which no clinical or paraclinical tests at present have been found useable for establishing the diagnosis. The disorders range from mild and transient to severe, chronic and disabling, and are common in all medical settings, both in primary and secondary care. FSD is costly for society due to high health care use, and the reduction of patients' labor market participation. Arguably, insufficient diagnostic availability is part of the reason some patients develop more severe, chronic and disabling FSD. The Diagnostic Clinic for FSD was set up at Regionshospitalet to alleviate this diagnostic need in the secondary care setting.

The DISTRESS trial is a pragmatic randomized clinical trial. After referral by their GP, patients are randomized 1:1 into two study arms: Intervention and Control. The referring GP must specify which diagnostic evaluations he/she requests both in the intervention and in the control group.

Intervention arm: Patients in this arm shall be examined by an internal medicine specialist trained in FSD diagnostic evaluation at The Diagnostic Clinic for FSD. After parallel evaluation for FSD and other physical conditions, patients are given their diagnosis, along with patient education in what FSD is, as well as a letter to their GP regarding recommended management and treatment options.

Control arm: The comparison group in the randomized clinical trial will receive diagnostic as usual at the Diagnostic center or elsewhere in the secondary sector in The Central Denmark Region.

In this clinical trial, the investigators aim to evaluate the effectiveness in terms of health-related utility improvement for the patients as well as the healthcare and societal costs and cost-effectiveness of the clinic, compared to diagnostic as usual. ;
