[Perception of doctors in different specialties of iron deficiency and iron deficiency anemia in Algeria in 2016: the SUPFER DZ survey].

Introduction: diagnostic methods and management of iron deficiency and iron deficiency anemia in clinical practice in Algeria is poorly known.

Methods: we conducted a cross-sectional survey among doctors in different specialties treating patients with iron deficiency anemia in 2016.

Results: data analysis was based on 349 questionnaires which were validated (anesthesia/resuscitation: 39; obstetrics and gynaecology: 111; oncology/Hematology: 71; hepato-gastroenterology: 64; cardiology: 36; internal medicine: 28). All specialties combined, 73% (254/349) of physicians thought that at least 30% of their patients had iron deficiency anemia; 65% of physicians (226/349) thought that at least 30% of their patients had iron deficiency. Iron deficiency was investigated systematically by 57% (63/111) of physicians of the group obstetrics and gynaecology, but only by 11% (26/238) of the remaining doctors; indeed, 82% (195/238) of physicians investigated it only in patients with anemia. The assessment of iron deficiency showed that the hemoglobin (Hb) was almost always determined (89%; 310/349) while laboratory tests to explore iron metabolism were inadequate: 70% (244/349) of physicians performed serum ferritin test and only 37% (128/349) performed transferrin saturation. Patients with iron deficiency (with or without anemia) received oral iron therapy (prescribed by 92% (322/349) of physicians) and iron injections therapy depending on Hb level (prescribed by 36% (127/349) of physicians).

Conclusion: this survey shows that iron deficiency is evaluated only in patients with anemia. In particular, laboratory tests to measure iron deficiency are insufficiently prescribed.
