Background:hospital-acquired anemia (HAA) is common, with an incidence that
ranges from nearly25% to 74%for the period ofhospitalization. Phlebotomy blood loss is
one ofthe etiologies and predictors of HAA in acute coronary syndrome patients. Aim of
this Study: identify the correlation between Phlebotomy blood loss and HAA among acute
coronary syndrome patients. Material and Method: Descriptive exploratory research
design was used to performthe research on one hundred and eighty patients in Cardiac
Care Units at Mahallah Cardiac Center. Patients' demographic, health-relevant laboratory
investigations data, drug-related data, and estimation of blood loss volume toolswere
utilized in the data collection process. Results: Around two-fifth (37.8%) of the studied
patients have HAA.There was a statistically significant correlation between HAA and
gender & length of hospital stay(X2: 5.229, P: 0.029&X2: 21.832, P:˂0.001 respectively).
On the otherhand, there was no significant correlation between HAA and phlebotomy blood
loss& patient's age (X2: 1.307, P: 0.520& X2: 1.7763, P: 0.620114 respectively).
Conclusion: Around two fifths (37.8%) of acute coronary syndrome patients had HAA
compared to 62.2% who were non-anemic. There was a statistically significant correlation
between HAA and gender & length of hospital stay. In contrast, there was no significant
correlation between HAA and phlebotomy blood loss and patient's age among acute
coronary syndrome patients atMahallah Cardiac Center.Recommendations: Future HAA
prevention efforts are recommended to be effective if they include multimodal interventions
that both decrease unnecessary phlebotomy blood loss through puncturing and bleeding.
