A 13-year time trend analysis of 3724 small bowel video capsule endoscopies and a forecast model during the financial crisis in Greece
INTRODUCTIONSince its introduction, small bowel video capsule endoscopy (VCE) use has evolved considerably. AIMEvaluation of the temporal changes of small bowel VCE utilization in three tertiary centers in Greece in Era 1 (2002–2009) and Era 2 (2010–2014) and the development a forecast model for fut...

AIMEvaluation of the temporal changes of small bowel VCE utilization in three tertiary centers in Greece in Era 1 (2002–2009) and Era 2 (2010–2014) and the development a forecast model for future VCE use during 2015–2017.
MATERIALS AND METHODSData from all small bowel VCE examinations were retrieved and analyzed in terms of the annual number of the performed examinations, their indications and the significance of their findings.
RESULTSOverall, we evaluated 3724 VCE examinations. The number of studies peaked in 2009 (n=595) and then decreased to reach 225 in 2014. Overall, more (53.8 vs. 51.4%) patients with iron-deficiency anemia and obscure gastrointestinal bleeding (IDA/OGIB) and fewer (10.7 vs. 14%) patients with chronic diarrhea were evaluated in Era 2 compared with Era 1 (P=0.046). In Era 2, there were more nondiagnostic examinations (39.5 vs. 29.3%, P |

MATERIALS AND METHODSData from all small bowel VCE examinations were retrieved and analyzed in terms of the annual number of the performed examinations, their indications and the significance of their findings.
RESULTSOverall, we evaluated 3724 VCE examinations. The number of studies peaked in 2009 (n=595) and then decreased to reach 225 in 2014.

In Era 2, there were more nondiagnostic examinations (39.5 vs. 29.3%, P<0.001), whereas the rate of cases with relevant findings decreased from 47.8 to 40.9%. According to the time trend analysis, we developed a forecast model with two scenariosthe pessimistic and the optimistic. Validation of the model with 2015 data showed that reality was close to the pessimistic scenariothe number of exams further decreased to 190, studies carried out for IDA/OGIB increased to 67%, and there were more negative than positive exams (40.7 vs. 39.2%).
CONCLUSIONThe number of VCE studies carried out after the emergence of the financial crisis decreased significantly and VCE indications were optimized. Our forecast model predicts lower numbers of VCE studies, with IDA/OGIB being the dominant indication. However, the predicted increase of negative exams requires further evaluation.</description><identifier>ISSN: 0954-691X</identifier><identifier>EISSN: 1473-5687</identifier><identifier>DOI: 10.1097/MEG.0000000000000771</identifier><identifier>PMID: 27775952</identifier><language>eng</language><publisher>England: Copyright Wolters Kluwer Health, Inc.
