Background/aim We evaluated the relevance of a systematic automatic detection of cirrhosis using biochemical markers in
hospitalized patients.
Methods We automatically calculated three free biochemical tests (APRI, Fib-4, and Forns) in patients consecutively hospitalized
in our university hospital between July and September, 2010. Patients > 18 years not known to suffer from chronic liver disease,
were contacted to undergo liver stiffness measurement (LSM) as a reference diagnostic tool. To limit false positives, we required
at least one APRI ≥ 2 (indicating cirrhosis) and Fib-4 >3.25 and/or Forns >6.9, without obvious overestimation.
Results A total of 10 035 APRI, 9903 Fib-4, and 1250 Forns were available in 4074 patients. The fibrosis tests were
independently influenced by the location of the patient, especially Cardiology (Lower Forns) and Hematology/Oncology
Departments (higher APRI, Fib-4, and Forns). Overall, 101 patients (2.48%) were suspected to have cirrhosis. LSM identified two
cases of cirrhosis (LSM > 13 kPa). In intent-to-diagnose analyses, the highest positive predictive values of the APRI, Fib-4, and
Forns for the diagnosis of cirrhosis were 1.98, 1.98, and 11.76%, respectively. The positive predictive value never exceeded 50%
in per-protocol analyses when considering patients with numerous positive results of the fibrosis tests.
Conclusion In hospitalized patients, automatic detection of cirrhosis on the basis of APRI, Fib-4, and Forns was inefficient
because of too many false-positive results. Eur J Gastroenterol Hepatol 28:74–81

Introduction
The evaluation of liver fibrosis in chronic liver disease is
crucial to determine the treatment decisions and the
screening for complications. The gold standard for the
diagnosis of liver fibrosis is the analysis of a liver biopsy
sample, which implies an invasive procedure [1], and is
hampered by sampling variability [2], and intraobserver
and interobserver variations [3]. In the last decade, non-
invasive assessment of liver fibrosis has been developed, on
the basis of composite tests using biochemical biomarkers
[4–10], and ultrasonic transient elastography (TE)
(FibroScan) [11]. The majority of these tools have been
validated extensively, particularly in the context of chronic
hepatitis C, and has limited the use of liver biopsy in
clinical practice. More recently, because liver fibrosis
progression is asymptomatic, the question of its screening
in patients unknown to suffer from chronic liver disease,
with or without risk factors, was raised. These noninvasive
tools have thus been used to establish the prevalence of
severe hepatic fibrosis in the general population [12,13] or
in patients with risk factors of nonalcoholic fatty liver
disease [14–16], but no evaluation of these procedures is
available to date in hospitalized patients. Hospitalized
patients may benefit from a systematic screening of liver
fibrosis because the risk factors of chronic liver disease are
probably more frequent than in the general population
[17]. Moreover, during hospitalization, many routine
biochemical tests are performed, which could be easily
processed automatically to calculate noninvasive liver
fibrosis scores without additional cost. The conditions for
an easy-to-perform systematic detection of cirrhosis thus
seem to be fulfilled.
The aim of this study was therefore to evaluate the
relevance of a systematic screening of cirrhosis using three
free biochemical tests (APRI, Fib-4, and Forns), auto-
matically calculated from routine biochemical tests per-
formed in a whole tertiary referral hospital.
Patients and methods
Study design
We carried out a monocentric, experimental intent-to-
diagnose study, in two steps (retrospective and pro-
spective), in a University hospital (Centre Hospitalier
Régional Universitaire, de Besançon) on all patients older
than 18 years of age admitted consecutively between 1 July
and 30 September 2010. The first step consisted of har-
vesting biochemical data and calculating fibrosis tests
