dc.description.abstractBackground: In nursing homes (NH) >80% have dementia, and 30-60% experience pain daily. Psychosis symptoms (delusions and hallucinations) are common. These can lead to reduced quality of life (QoL) and are often treated with antipsychotic medication, which can cause harmful side-effects. Previous studies have suggested an association between pain and psychosis symptoms, but none have investigated the longitudinal association as well as the effect of pain treatment on psychosis. Aim: To investigate the relationship between pain and psychosis symptoms, and the characteristics of NH patients with psychosis symptoms. The thesis also aims to investigate the effect of pain treatment on psychosis symptoms and the effect of a multicomponent intervention on psychosis symptoms and pain. Methods: Paper 1 investigates the effect of pain treatment on psychosis symptoms and uses data from a cluster-randomized controlled trial (cRCT), the Pain-BPSD study. Papers 2 and 3 use data from a cRCT, the COSMOS-trial, and investigate the characteristics of NH residents with psychosis symptoms, as well as the association between pain and psychosis symptoms over time and the effect of a multicomponent intervention on pain and psychosis. Pain was measured using the MOBID-2 pain scale, while psychosis symptoms are measured using the NPI-NH. Results: Paper 1 included 352 residents from 60 NH units, while the COSMOS-trial included 723 residents from 67 NH units. Pain treatment reduced psychosis symptoms (p = 0.034). Residents with psychosis had lower QoL (p <0.001) and more depressive symptoms (p <0.001). Pain was longitudinally associated with psychosis symptoms as a group (p = 0.009) and delusion individually (p = 0.007). The COSMOS-intervention had no effect on total pain or psychosis symptoms. Conclusion: Pain in NH residents was associated with psychosis symptoms as a group and delusion individually. Psychosis symptoms were associated with depression and lower QoL. The effect of non-pharmacological interventions on psychosis symptoms needs further research. Implications: Pain assessment should be a prerequisite when making treatment decisions on psychosis symptoms in NH residents. Thorough guidelines for treating psychosis symptoms in NHs need to be developed to reduce their negative impact.en_US
dc.description.abstractBakgrunn: På sykehjem (SH) har over 80% demens, og 30-60% opplever daglig smerte. Psykosesymptomer er vanlig, kan føre til redusert livskvalitet, og behandles ofte med antipsykotika som kan gi skadelige bivirkninger. Tidligere studier indikerer en sammenheng mellom smerte og psykosesymptomer, men ingen har undersøkt den longitudinelle sammenhengen, eller effekten av smertebehandling på psykose. Formål: Undersøke sammenhengen mellom smerte og psykosesymptomer, samt karakteristika til SH-pasienter med psykosesymptomer. Avhandlingen undersøker også effekten av smertebehandling på psykosesymptomer, samt effekten av en multikomponent-intervensjon på psykosesymptomer og smerte. Metode: Artikkel 1 undersøker effekten av smertebehandling på psykosesymptomer, og analyser data fra den klynge-randomiserte kontrollerte, Pain-BPSD studien. Artikkel 2 og 3 bruker data fra den klyngerandomiserte kontrollerte KOSMOSstudien, og undersøker karakteristika til SH pasienter med psykosesymptomer, i tillegg til sammenhengen mellom smerte og psykose over tid, samt effekten av en multikomponent intervensjon på smerte og psykose. Smerte måles med MOBID-2 smerteskala. Nevropsykiatrisk intervjuguide – SH-versjon brukes for å måle psykose. Resultat: Artikkel 1 inkluderte 352 pasienter fra 60 SH avdelinger, mens KOSMOSstudien inkluderte 545 pasienter fra 67 SH avdelinger. Smertebehandling reduserte psykosesymptomer (p = 0.034). Pasienter med psykosesymptomer hadde lavere livskvalitet (p <0.001) og mer depresjonssymptomer (p <0.001). Smerte var longitudinelt assosiert til psykosesymptomer som gruppe (p = 0.009), og vrangforestillinger individuelt (p = 0.007). KOSMOS-intervensjonen hadde ingen effekt på total smerte eller psykosesymptomer. Konklusjon: Smerte er assosiert med psykosesymptomer som gruppe, og vrangforestillinger individuelt. Psykosesymptomer er assosiert med lavere livskvalitet, og har negativ påvirkning på SH pasienter. Effekten av ikkefarmakologiske intervensjoner på psykosesymptomer trenger videre undersøkelse. Implikasjoner: Smertevurdering bør være standard når en skal vurdere behandlingsvalg for psykosesymptomer. Klare retningslinjer trengs for behandling av psykosesymptomer for å redusere de negative konsekvensene de har.en_US
