Factors associated with clinical outcome in geriatric acute cholangitis patients.

We aimed to determine the risk factors associated with the clinical outcome in cases of acute cholangitis among the geriatric age group. Patients aged >65 years hospitalized with the diagnosis of acute cholangitis in an emergency internal medicine clinic were included in this study. The study population comprised 300 patients. In the oldest-old group, the rates of severe acute cholangitis and intensive care unit hospitalization (39.1% vs. 23.2%, p<0.001) were higher. The mortality rate was also higher in the oldest-old group (10.4% vs. 5.9%, p=0.045). The presence of malignancy, ICU hospitalization, decreased platelet levels, decreased hemoglobin levels, and decreased albumin levels were associated with mortality. In the multivariable regression model in which variables associated with Tokyo severity were included, the associated factors for membership in the severe risk group compared to the moderate risk group were decreased platelet count (OR: 0.96; p=0.040) and decreased albumin level (OR: 0.93; p=0.027). Increasing age (OR: 1.07; p=0.001), malignancy etiology (OR: 5.03; p<0.001), increasing Tokyo severity (OR: 7.61; p<0.001), and decreasing lymphocyte count (OR: 0.49; p=0.032) were determined to be associated with ICU admission. Decreasing albumin levels (OR: 0.86; p=0.021) and ICU admission (OR: 16.43; p=0.008) were determined to be factors associated with mortality. Worse clinical outcomes occur among geriatric patients with increasing age.
