A comprehensive retrospective review of ınpatient hematology consultations at a tertiary care hospital

Aim: Hematological parameters are affected by many hematological and non-hematological reasons. In many diseases, values that go beyond normal limits are often a reason for consultation by physicians in other branches of science. In our study, what consultations are requested from hematology in patients hospitalized in our hospital, the most common hematological problems encountered by the departments, and the results of the consultations were examined. Material and Methods: A total of 684 consultations were retrospectively scanned between 2022 and 2023, based on the information obtained from the hospital data system. The study examined the requesting department, consultation reason, patients’ comorbid conditions, history of hematologic disorders, hematologic and non-hematologic diagnoses following the consultation, and assessments using peripheral smears and biopsies. Results: 59.50% of the consultations were requested from internal departments, while 40.50% were requested from surgical departments. The most common reason for requesting consultation was found to be cytopenias with 41.96%. The most common reason for consultation requested for cytopenia was thrombocytopenia. While 45.50% of the consultations were evaluated with peripheral smear, 10.20% were evaluated with bone marrow biopsy. Conclusion: We determined the issues on which physicians in other departments most frequently felt the need for consultation, how many of these resulted in a hematological diagnosis, and the non-hematological diagnoses that most affected blood parameters. We believe that the results of our study will be guiding in training programs and preparation of consultation books.
