Abstract
Background: Delirium is commonly found in the elderly patient which associated morbidity and mortality unless causes has not been thoroughly indentified or unaware of the associated factors. Consequently results in poor clinical outcome.
Objective: To identify the factors associated with acute delirium in hospitalized patients in medical ward
Setting: Medical ward, Sangkha hospital
Research design: A case-control study
Material and Methods: Demographic data of the hospitalized patients in medical ward of Sangkha hospital as inclusion criteria included age, gender, marital status, comorbidities, smoking, alcohol consumption, infections, prescribed medications during hospital stay, urinary catheter retained device using , history of surgery, pain, depression and laboratory result. Delirium was diagnosed according to diagnostic criteria by Confusion Association Method. Data was ana lyzed by SPSS program.
Results: Research data was collected from 181 patients who admitted to medical ward in Sangkha hospital. The patients were divided into 2 groups: patient with delirium 53 cases and patient without delirium 128 cases. Mean of age in patients with delirium was greater than those of patient without delirium with statistically significant (75.75 ±10.64 versus 57.7 ± 15.83 years, p-value 0.00). Multivariate analysis revealed that patients with delirium were associated with following factors; patient aged 65 years or higher (p-value 0.00, OR = 9.23, 95% Cl 3.89-21.85), benzodiazepine use (p- value 0.002, OR= 3.45, 95% Cl 1.85-7.52) and retained urinary catheter (p-value =0.003, OR=19.18, 95% Cl 2.8-130.94) in which significantly greater than patients without delirium Conclusion : The significant factors associated with delirium were aged 65 years or higher, receiving benzodiazepine and retained urinary catheters. Delirium should be monitored in patient with associated factors and promptly managed by causes or the affecting factors in order to improve patient care outcome.
