Background: Iron deficiency anaemia (IDA) is the most prevalent type of anaemia and a common cause for patient referrals to the haematology outpatient clinic. The aim of this study was to determine the number of patients with IDA treated at the Haematology Outpatient Clinic of the UMC Ljubljana in the period of two years, as well as to inquire into the causes for their referrals to the clinic, patient characteristics, their complete blood count results at initial examination, the prescribed therapy, the number and the causes of their follow-up visits. We draw special attention to the IDA onset mechanism, the microcytic anaemia therapy principles and the indications prompting a referral of an IDA patient to the haematology specialist.
Methods: We undertook a retrospective analysis of the medical records of patients who were referred to the Haematology outpatient clinic of the UMC Ljubljana for examination in the two-year period between 1 January 2014 and 31 December 2015 and had been diagnosed with IDA on the basis of their clinical picture and their CBC values. Data were collected with the Hipokrat IT system and statistically evaluated with Microsoft Excel.
Results: In the period relevant for our research, 277 patients of those who were referred to the Haematology outpatient clinic for medical examination were diagnosed with IDA. 11.6 % of these patients were male and 88.4 % female; 62.1 % of the female patients were of childbearing age. IDA was specified as the referral diagnosis in the cases of no more than 39 % of the patients referred to the specialist outpatient clinic, whilst the medical condition of the remaining percentage of patients was not identified by the referring doctor. Comorbidities were observed in 50.2 % of the patients, and for 62.5 % of the patients a follow-up appointment was scheduled by the treating haematologist. Of all patients, 63.5 % were treated with an intravenous iron preparation during their first examination at the outpatient clinic and a transfusion of erythrocytes was administered during such an examination to 4.3 % of the patients.
Conclusion: Patients with IDA were often treated at our Haematology Outpatient Clinic in the relevant two-year period. The data indicates a poor recognition rate of this prevalent type of anaemia. IDA is not a blood disorder and the referral of IDA patients to the Haematology Outpatient Clinic is justified in the case of severe microcytic anaemia, when the patient does not respond to the oral or intravenous iron replacement therapy or if a concomitant change in the CBC persists despite the effective treatment with iron preparations.
