Forskningsprogram i mortalitet og morbiditet
Forskningsprogrammet er etableret 1. januar 2016. Seneste opdatering 15. februar 2024.
Forskningsprogrammet retter sig mod at undersøge forekomst og betydning af somatisk og psykiatrisk co-morbiditet ved svære psykiatriske lidelser, samt udvikling af psykiatriske lidelser i befolkningen.
Udover udarbejdelse af originalarbejder rummer aktiviteterne udarbejdelse af oversigtsarbejder.
Programmet fokuserer på klinisk forskning i bred forstand, herunder også nationale registerprojekter. Deltagere i forsøg rekrutteres fra forskellige settings.
Programansvarlig
Professor, overlæge, ph.d. René Ernst Nielsen.
René Ernst Nielsen primære forskningsinteresser er registerbaseret forskning i mortalitet og morbiditet ved svær psykiatrisk sygdom samt forskning i affektive sindslidelser. Han fungerer som vejleder for flere projekter under forskningsprogrammerne Affektive Sindslidelser og Mortalitet og Morbiditet ved Svær Psykiatrisk Sygdom. Ved siden af sine forskningsmæssige aktiviteter fungerer René Ernst Nielsen som overlæge i Psykiatrien, Region Nordjylland og varetager funktionen som assisterende redaktør på Nordic Journal of Psychiatry og BMC Psychiatry.
