Abstract

|

Background: This study was done to investigate the clinical risk factors of delirium in general hospital’s elderly inpatients.
Methods: A case-control study design was used. Forty cases and age-sex matched 120 controls were
identified using hospital discharge data from June 1995 to May 2001. The controls were selected during the same period. The clinical records of each subject were reviewed using discharged disease code to select cases. Subsequently, the data were recorded from clinical records.
Results: The subjects admitted with delirium tended to have increased age (P=0.007), hypoxia (P=0.018), low hemoglobin (P=0.011), sleep disturbance (P=0.001), more ADL total dependence (P=0.018), diagnoses with infections (P=0.006), diabetes (P=0.046), and hypertension (P=0.041). Above risk factors seemed to be clinically associated with delirium.
Conclusion: These findings indicate that rapid infection control, maintenance of good sleep hygiene, well-controlled diabetes and hypertension, and correction of hypoxia may help to prevent delirium in general hospital’s elderly inpatients.
