Journal Title: PARIPEX-Indian Journal of Research - Year 2017, Vol 6, Issue 10
Abstract
Background: Delirium is a serious mental disorder commonly experienced by hospitalized elderly patients. The prevalence, detection, pathophysiology, prevention, treatment and outcomes of delirium are still leading challenges for medical practitioners and other healthcare providers. Objectives: The current study was undertaken to measure the prevalence of delirium in patients admitted to medical wards in our institute. The potential risk factors associated with delirium including effects of delirium on mortality and length of stay of the patients in the hospital were also studied. Methods: We assessed elderly patients admitted to the medical wards at King Abdulaziz University Hospital in Jeddah for the presence or absence of delirium. Testing took place between March 27th, 2012 and March 31st, 2012. The diagnosis of delirium was based on the confusion assessment method (CAM). Results: A total of 144 patients were admitted to the medical wards at the time of the study, of whom, 52 were eligible for the study. Thirteen cases of delirium were detected, with a prevalence of 36.1%. Factors associated with the development of delirium were hypertension and bronchial asthma (p=0.040 and 0.038, respectively). The regression adjustment model showed that coronary artery diseases (p=0.018) and chronic kidney diseases (p=0.009) were also significant predictors of delirium. Furthermore, the diagnosis of delirium was strongly related to a longer hospital stay (p=0.011), and deaths were more frequent among patients with delirium, but the association between delirium and mortality did not reach statistical significance (p=0.242). Conclusions: Delirium was highly prevalent in this sample of elderly medical inpatients in Saudi Arabia, with a significant impact on hospital length of stay and a possible increase in mortality. Further studies are needed to elucidate the details of this condition in our hospitals and to guide preventive and educational efforts.
