Inclusion criteria

Inclusion criteria: Inclusion Criteria ? Adults aged = 18 years at time of hospital admission. ? Patients will be admitted to the selected wards (e.g., internal medicine, critical care units) during the study period for medical (non-surgical) causes ? Documented hemoglobin (Hb) value on admission (within 24 hours of admission). ? At least 2 follow-up Hb measurements during hospitalization (to detect HAA ? Hospital stay of = 24 hours (to exclude very short admissions where HAA cannot develop). ? Provides informed consent

Exclusion criteria

Exclusion criteria: ? Active major bleeding at the time of admission (e.g., GI hemorrhage, trauma with ongoing hemorrhage). ? Received blood transfusion before admission or within the first 24 hours from outside the admitting hospital ? Postoperative patients admitted immediately after major surgery with perioperative blood loss already documented ? Patients with incomplete or missing Hb data (no baseline or no follow-up Hb to determine HAA). ? Terminal palliative care patients where active diagnostic/therapeutic management of anemia is not intended ? Patients discharged, transferred, or died within <24 hours of admission.
