BACKGROUND:Treatmentofinvasivecandidiasis(IC)israpidlydevelopingduetotheemergenceofFKS-mediatedechinocandin(echino)-resistantCandida species.Preventionofechino resistancewillrequiredevelopmentofmorepotentechinos oroptimizingcurrentechino use.Thepurposeofthisstudywastoevaluatereal-worldechinoutilizationinhospitalizedpatientswithsuspectedorconfirmedICtogaininsightintoantimicrobialstewardshipinterventions.
METHODS:Patientsadmittedtoan800-bedquaternarycarehospitalin2015-2016givenanechino wereidentified.Datafromarandomsampleofallpatientsgivenanechino wascomparedtothatofechino-treatedpatientsIC(candidemia).Areasforstewardshipinterventionsincludingspecialpopulationsandunmetmedicalneedswereidentified.
RESULTS:Fivehundredandthirteenpatientsreceived579coursesofechino therapywithamediantreatmentdurationof6days(IQR:3-12days).Ofthese,150patients(51%male)aged60±16years(ICU:64%;corticosteroids:56%)wererandomlyselectedandcomparedto59patients(47%male)aged55±16years(ICU:81%;corticosteroids:39%)withcandidemia.Globally,echinos werestarted15±19daysfromadmissionforanaveragein-hospitaldurationof6.6±5.9days.Ofthe150randomlyselectedpatients,97(65%)hadapositiveyeastculture(C.albicans:43.3%)fromanon-sterilesite(urine:51%;sputum:28%),and16hadcandidemia (11%).Patientswerecommonlyco-administeredfluconazole(31%),anotherazole(11%),oranamphotericinBproduct(10%).Oneisolatehadreducedsusceptibilitytoechinos.Inthe59patientswithcandidemia (C.albicans:45%;C.glabrata:33%),echinos werestarted12±18daysfromadmissionforanaveragein-hospitaltherapydurationof11±28days.Patientswerecommonlyco-administeredfluconazole(53%),anotherazole(12%),oranamphotericinBproduct(24%).Ninepatients(15%)withcandidemiacontinuedtorequireanechino afterdischarge.Threeisolateshadreducedsusceptibilitytoechinos.
