Abstract
Background: Delirium in hospitalised older persons is common and is correlated with adverse outcomes. Few studies of this have been done in New Zealand. This study aimed to measure prevalence of delirium in older adults indifferent specialities in two different hospitals. Objective: The aim of the study was to find out point prevalence of delirium in older adults in hospital setting. Methods: The subjects (n=1024) were older inpatients (>65 years; >55years if of Maori descent) surveyed over a period of 18 months. Delirium was screened for using the Confusion Assessment Method (CAM) Diagnostic algorithm. We evaluated for delirium following a detailed review of the presenting history, Mini Mental state examination (MMSE), digit span test and CAM evaluation. Results: Overall prevalence of delirium was 7.84% in older adult patients (N 1045). There was no difference in delirium among genders (p=0.24). Prevalence of delirium in older patients from medical wards was 8.7%, surgical wards were 7.5% and in rehabilitation wards were 7.7%. The average MMSE score was 24.2 (SD 5.0), the average CAM score for positive patients was 18.8 (SD 4.6). Average Memorial Delirium Assessment Scale score indicating severity of delirium was 13.13 (SD 4.8). Conclusion: Delirium remains an important diagnosis which should be considered among hospitalized older patients. Results suggested a lower prevalence of delirium in our group of patients. Results of the study are discussed with relevance to its generalizability in various settings.
