Variables associated with antibiotic administration for performing paracentesis among patients with ascites in a community hospital

Aim of the study:
Early paracentesis before antibiotic administration reduces morbidity and mortality in patients with decompensated cirrhosis. We studied the association of variables with antibiotic administration before or after performing paracentesis.

Material and methods:
This was a retrospective study of 137 patients with ascites secondary to cirrhosis admitted to a community hospital in New York City. Predictor variables were demographic, disease-related, admission timing, and serum measurement.

Results:
We found a significantly increased relative risk for performing paracentesis after antibiotic administration for those admitted at night (relative risk ratio [RRR] = 3.01, 95% CI: 1.02-8.85, p = 0.046). Demographic, disease-related, and serum measurement variables were not significantly associated with performing paracentesis or order of antibiotic administration. Also, increased body mass index was significantly associated with decreased relative risk for paracentesis not done (RRR = 0.84, 95% CI: 0.74-0.96, p = 0.01).

Conclusions:
In conclusion, there was increased relative risk for performing paracentesis after antibiotic administration for patients admitted at night. We recommend ongoing resident and hospitalist training to maintain competency in bedside procedures such as paracentesis for patients with cirrhosis. Also, increased staffing or the presence of a resident/hospitalist led interventional team during night shifts may also help optimize the rates of timely paracentesis.
