Evaluating The Cost-Consequence Of A Standardized Strategy For The Etiological Diagnosis Of Uveitis (Ulisse Study)

Main objectiveTo prospectively assess the cost-consequence of a standardized diagnostic strategy as to compared to an open one for the etiological diagnosis of uveitis.DesignThis was a prospective, non-inferiority, multicentre, randomized controlled trial.MethodsWe included all consecutive patients with uveitis who had visited at least one of the Departments of Ophthalmology. In the standardized group, patients had a minimal work-up regardless of the type of uveitis (including evaluation of the CBC, ESR, C-reactive protein, tuberculin skin test, syphilis serology and chest X-ray). Depending on ophthalmological findings, further investigations could be performed. In the open strategy, ophthalmologists were free to order any kind of investigation. The main outcome was the mean cost per patient of each strategy.Results903 uveitis patients were included from January, 2010 to May, 2013. The mean cost per patient of the standardized strategy was 182.97 euros [CI 95% (173.14; 192.80)], and the mean cost per patient of the open strategy was 251.75 euros [CI 95% (229.24; 274.25)]. Therefore, the mean cost per patient of the standardized strategy was significantly lower than the mean cost per patient of the open strategy (p < 0.001). There were significantly fewer visits (p < 0.001), fewer radiological procedures (p < 0.004) and fewer laboratory investigations (p < 0.001) in the standardized group.ConclusionA standardized strategy is a cost-saving approach for the etiological diagnosis of uveitis.
