Conclusionsandresults
Safety:UroVysionFISHAssayisasafe,non-invasivetestperformedonvoidedurine.
Effectiveness:ThesensitivityoftheUroVysiontestrangedfrom48%to86%,andthe specificityrangedfrom34%to100%.Basedontheseresultsandconsiderationofvarious pretestprobabilitiesofrecurrence,theclinicalimpactofadoptingUrovysionislikelytobe greatestinpatientswithahighriskofTCCrecurrencewhohaveundergoneatleast1yearof follow-up.Inthesepatients,usingtheUroVysiontesttoselectwhetherafollow-up cystoscopyunderlocalanaesthetic(followinganegativeUrovysiontest)orgeneral anaesthetic(followingapositiveUrovysiontest)isrequiredmeansthatonlyasmallnumber ofpatientswouldunnecessarilyundergocystoscopyundergeneralanaesthetic,andmost patientswouldundergoonlyonecystoscopy,ratherthantwo.Theprobabilityofmissinga recurrencefollowinganegativeUrovysionincreasesinpatientswithhigherrisksorin patientsatlaterstagesintheirfollow-up.
Cost-effectiveness:AneconomicmodelshowedthatthecostsofadoptingUroVysionexceed thecostsofcurrentpractice.Atfiveyears,thecostofadoptingUroVysionwas$7835, comparedto$5959forcurrentpractice.One-waysensitivityanalysesshowedthatunderany plausiblevariationofevidenceofaccuracy,costsorratesofrecurrence,theuseofthe UroVysiontestremainedmorecostlythancurrentpracticewiththeequivalentexpected clinicaloutcomes.
Recommendation:MSACrecommendedthatonthestrengthofevidencepertainingto UroysionFISHassaypublicfundingshouldnotbesupportedforthisprocedure.Theclinical usefulnessofthetestislimitedby thesensitivityandexpenseofthetestandthecost effectivenesswasnotdemonstrated.TheMinisterforHealthandAgeingacceptedthis recommendationon28March2006.
