Objective Early paracentesis (EP) for rapid diagnosis of spontaneous bacterial peritonitis is considered best practice in the care of admitted patients with cirrhosis and ascites, but inpatient paracentesis is frequently not performed or delayed. We developed a quality improvement (QI) initiative aimed at increasing the proportion of admitted patients with cirrhosis who undergo paracentesis and EP.

Design Pre–post study of a QI initiative.

Setting A tertiary care hospital in a major metropolitan area.

Patients Hospitalised patients with cirrhosis and ascites.

Interventions We targeted care providers in the emergency department (ED) by raising awareness of the importance of EP, developing criteria to identify patients at highest risk of SBP who were prioritised for EP by ED providers and restructuring the ED environment to enable timely paracentesis.

Results 76 patients meeting inclusion criteria were admitted during the postintervention 9-month study period. Of these, 91% (69/76) underwent paracentesis during admission versus 71 % (77/109) preintervention (p=0.001). 81% (56/69) underwent EP within 12 hours of presentation or after a predefined acceptable reason for delay versus 48% (37/77) preintervention (p=0.001). There were no significant differences in in-hospital mortality or length of stay before and after intervention.

Conclusion A multidisciplinary QI intervention targeting care in the ED successfully increased the proportion of patients with cirrhosis and ascites undergoing diagnostic paracentesis during admission and EP within 12 hours of presentation.
