Background Hospital acquired anemia is a frequent complication in intensive care units that leads to
negative outcomes, higher morbidity and mortality for critically ill patients .Aim Assess predictors
of hospital acquired anemia among critically ill patients. Design: A descriptive correlation study
design Setting: This study was conducted at Surgical Intensive Care Unit at Tanta Emergency
Hospital affiliated to Ministry of higher education and scientific research. Subjects: Purposive
sampling of 100 patients who met all inclusion criteria was included. Tools: Three tools were used
for data collection. Tool (I): Hospital Acquired Anemia Assessment Tool, Tool (II): Predictors of
Hospital Acquired Anemia Assessment Tool and Tool (III): Physiological Indices Assessment Tool.
Result: The mean hemoglobin level decreased significantly from (13.17± 1.07) on admission to
(9.94± 1.73) at 7th day of the study where p (0.000*), significance relation was observed between
diagnosis and severity of anemia on 3rd day and 7th day where p (0.047*) and (0.037*) respectively
and more than half of studied patients had hospital acquired anemia related nursing practice
throughout the period of study. Conclusion: The studied patients developed Hospital acquired
anemia during their ICU stay. There were statistically significance relation between diagnosis and
severity of anemia on 3rd day and 7th day of the study. Also there were significant correlation among
level of consciousness, physiological indices regarding respiratory rate, MAP and severity of anemia.
Recommendation: Preform a comprehensive patient monitoring and assessment for early detection
and intervention of hospital acquired anemia.
