Who benefits from multidisciplinary care in functional somatic disorders? Identifying cost-effective patient selection through diagnostic classification groups.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFunctional Somatic Disorders (FSD) significantly impact patients' quality of life while placing a substantial economic burden on healthcare systems. Identifying which patients achieve reductions in healthcare costs through multidisciplinary care remains crucial for optimizing resource allocation.
methodsA retrospective analysis examined healthcare utilization and costs during the year preceding and the year following patients' initiation of treatment at a specialized, multidisciplinary clinic in Israel. The clinic combined medical care with mind-body therapies - including cognitive behavioral therapy, hypnotherapy, and physiotherapy. Using baseline characteristics, patients were divided into Diagnostic Classification Groups (DCG). A multivariable analysis was performed to ascertain the impact of DCG on annual, average changes in healthcare utilization and costs after treatment.
resultsData from N = 685 patients were analyzed. Reduced healthcare utilization and costs were observed among approximately 56% of the population receiving multidisciplinary care. Mean annual cost reductions were 1,367 ILS per patient. Specifically, significant reductions were observed in hospitalizations (-1,723 ILS) and diagnostic procedures (-495 ILS). Patients with simple FSD and stress-exacerbated diseases showed significant cost reductions (P < 0.05), while those with organic disease or difficult FSD did not demonstrate significant changes. Analysis by DCG revealed that baseline diagnostic classification significantly predicted cost reduction.
conclusionHealthcare utilization and costs were reduced among FSD patients receiving multidisciplinary treatment, with outcomes varying by diagnostic classification. Baseline diagnostic classification reliably predicted treatment cost-effectiveness, underlining the economic value of collaborative care for patients with simple functional disorders and stress-exacerbated diseases. These diagnostic patterns provide healthcare policymakers with selection criteria for multidisciplinary programs and inform the development of tailored interventions.
