Total numberof dischargesYear Since 2004, hospitalizations of patients with HE have been increasingBased on hospital discharge data from the Healthcare Cost and Utilization Project and using ICD-9-CM codes 291.2, 348.30, and 572.2291.2 = alcoholic dementia, not elsewhere classified348.30 = encephalopathy, not otherwise specified572.2 = hepatic coma In 2009, there were more than 345,000 hospitalizations for patients with HE

Choice of maintenance therapy following an OHE episode has a significant effect on overall costs associated with overt hepatic encephalopathyRifaximin is nearly 50% more cost efficient than lactulose monotherapy or lactulose/ rifaximin combination therapyRifaximin therapy results in less frequent hospitalizations and longer intervals between readmissions

Noncompliance inferred with evidence (as documented in patient charts) of discontinuation of Lactulose as prescribed (determined by questioning patient or family members); lack of Lactulose refill according to pharmacy records; and 4 bowel movements/day with dehydration and azotemia (new rise in serum creatinine >1.5 mg/dL).Bajaj JS, et al.

Need for InterventionsExpanding evidence shows serious deficits in quality exist for patients undergoing transitions across sites of carePatients are often unprepared for self-management roleReceive conflicting information about management of their chronic illnessOften unable to contact care provider

Care Transition Interventions StudyRandomized, controlled trialConducted in collaboration with large not-for-profit capitated delivery system with more than 60,000 patients 65 years and older in ColoradoContracts with a single hospital, 8 SNFs, and 1 home health care agencyBefore initiation, hospital 30-day readmission rate was ~15%750 Patients were randomized in study, 712 included in analysis (stroke, CHF, CAD, arrhythmia, COPD, DM, hip fracture, dehydration, PNA)
