title: Gaps in recognition and evaluation of incidentally identified hepatic steatosis.
abstract: BACKGROUND
  Nonalcoholic fatty liver disease (NAFLD), the most common cause of liver disease, is frequently diagnosed incidentally on imaging. The goal of the present study was to characterize rates of documentation and evaluation of incidentally identified steatosis.
  
  
  METHODS
  Adults who underwent abdominal computed tomography with incidentally reported steatosis from January 2008 to October 2011 and with ≥1 primary care appointment within 14 months following imaging were included.
  
  
  RESULTS
  One hundred twenty-seven individuals with newly identified steatosis on imaging were included. Medical record documentation of newly identified steatosis occurred in only 29 individuals (22.8 %). Mention of steatosis within the "impression" section of radiology reports in addition to the report body was associated with significantly higher likelihood of primary care documentation (p = 0.007). Primary care documentation of steatosis was associated higher rates of evaluation for the etiology of steatosis include testing of aminotransferase levels (96.5 vs. 77.5 %, p = 0.025), alcohol use screening (89.6 vs. 66.3 %, p = 0.02), and hepatitis C screening (20.6 vs. 2.0 %, p = 0.002). No patient had documentation of the NAFLD fibrosis score and none were referred for specialist evaluation or for liver biopsy. However, when calculated, the NAFLD fibrosis score identified 14 patients (11 %) as high risk for advanced hepatic fibrosis.
  
  
  CONCLUSIONS
  Documentation of incidentally identified steatosis is infrequent but was improved when steatosis was mentioned in the "impression" of radiographic reports. Documentation of steatosis was associated with increased rates of aminotransferase testing and alcohol use and hepatitis C screening. An important proportion of individuals with incidentally identified steatosis are at high risk of fibrosis and may benefit from additional evaluation.
