1437 Histological Examination in Search of Helicobacter Pylori in Iron Deficiency Anaemia: An Unnecessary Expense?

Abstract

Abstract Aim The British Society of Gastroenterology guidelines recommend Helicobacter pylori (HP) testing in patients with iron deficiency anaemia (IDA). This quality improvement project evaluates the utility of histological examination for HP in IDA patients, the consequent expenditure and whether a more cost-effective alternative exists. Method A retrospective search was conducted of patients within a four-month period who underwent an oesophago-gastroduodenoscopy (OGD) for IDA. Patients with an identifiable cause of IDA, ferritin >40ug/mL and haemoglobin (Hb) >12g/L in women or > 13g/L in men were excluded. The costings of a single tissue biopsy and HP stool testing were sought from our local departments. Results Ninety-nine patients’ results were analysed after exclusions (n = 99/127, 78.0%). All patients had biopsies taken at OGD. On average, three biopsies were obtained per patient. Forty-two patients had no abnormalities visualized on OGD and all ninety-nine patients were HP negative. A single biopsy costs £70; £65 per hematoxylin and eosin based histological examination and £5 per single-use biopsy forceps. Accounting for forty-two patients with macroscopically normal OGDs leads to a total expenditure of £8820. A HP stool test costs £14. Conclusions Guidelines recommend HP testing either non-invasively or at OGD as an alternative strategy, based on weak evidence that HP may cause IDA. HP prevalence is falling; histological examination of biopsies obtained at OGD therefore appears expensive and unnecessary. It is more cost effective to perform a stool test in the case of a normal OGD and commence treatment accordingly with biopsies reserved when otherwise clinically indicated and not solely for HP testing.
