IntroductionResearch shows a high prevalence of mental disorders and psychotropic medication among older people, especially in nursing homes. Knowledge of this concerning issue among Icelandic nursing homes residents is limited, despite its importance for mental health policymaking. Therefore, the aim of this study was to investigate the prevalence of psychiatric diagnoses and psychotropic medication in Icelandic nursing homes, the relationship between these factors and how they have evolved from 2003 to 2018.Material And MethodsThe research data comes from interRAI MDS 2.0 assessments for nursing home residents in Iceland, for the period 2003-2018. The study uses the last assessment of each year (N=47,526).ResultsApproximately half of the residents were diagnosed with anxiety and/or depression; 49.4% in 2003 and 54.5% in 2018. The use of psychotropic drugs increased from 66.3% to 72.5%. Antidepressants were most commonly utilized, with an increase from 47.5% to 56.2%. The use of antipsychotics drugs has remained nearly unchanged, at around 26%. Inconsistency was found between psychotropic medication and psychiatric diagnoses; on average, 18.2% of the residents took psychotropic drugs without being diagnosed and 22.3% took antipsychotics in other cases than recommended.ConclusionAge related changes influence the effect of psychotropic drugs and studies have not supported their positive long-term effects for older people who are also sensitive to associated adverse effects, especially in cases of polypharmacy. Therefore, it is important that psychotropic drugs use is based on accurate mental health assessment. To reduce psychotropic medication, other mental health interventions need to be developed.
