The Health Care Burden of Hepatic Encephalopathy.

Hepatic encephalopathy-a common and debilitating complication of cirrhosis-results in major health care burden on both patients and caregivers through direct and indirect costs. In addition to risk of falls, inability to work and drive, patients with hepatic encephalopathy often require hospital admission (and often readmission), and many require subacute care following hospitalization. The costs and psychological impact of liver transplantation often ensue. As the prevalence of chronic liver disease increases throughout the United States, the health care burden of hepatic encephalopathy will continue to grow.

The assessment and management of cirrhotic patients with encephalopathy.

Hepatic encephalopathy (HE) is a debilitating complication associated with both acute and chronic liver injury. It is associated with a greater risk of death than any other significant hepatic decompensation event. It manifests as a wide spectrum of neuropsychological abnormalities ranging from subtle impairments in higher cognitive function, to confusion and coma. The pathophysiological role of ammonia in the development of HE is well known, but there is increasing recognition that the gut microbiome, gut-derived systemic inflammation and development of infection can serve as drivers of HE in patients with cirrhosis. The development of HE portents to the severity of cirrhosis and the prognosis is poor without liver transplantation. A referral for liver transplantation should therefore be considered early in those who are eligible. This review covers the pragmatic assessment of HE in patients with cirrhosis, as well as the current evidence base for the best practice management of HE in such patients.
