Prevalence of postoperative anemia and associated factors among adult patients who undergone surgery during COVID 19 Era (Preprint)

Abstract

BACKGROUND Background: Anemia maximizes the risk of oxygen deprivation; as well it increases the risk of perioperative morbidity and mortality. There are low levels of evidence regarding postoperative anemia prevalence in developing countries. This study aimed to determine the prevalence of postoperative anemia and associated factors among post-surgical patients at Debre Tabor Comprehensive Specialized Hospital, in Northern Ethiopia. OBJECTIVE To determine the prevalence of postoperative anemia and associated factors among adult patients who undergone surgery at Debre Tabor Comprehensive Specialized Hospital, Northern Ethiopia, from April 1 to August 30, 2021. METHODS Hospital-based cross-sectional study was conducted on surgical patients and data was collected by using an interviewer-administered semi-structured questionnaire. Data entry and analysis were done with SPSS version 23. descriptive data were reported using tables and graphs. Bivariable and multivariable analysis was performed to determine whether each of the independent variables is associated with the outcome variable. RESULTS A total of 409 surgical adult patients were included in this study. The hemoglobin test result revealed that 203 (49.6 %) of the participants were anemic during discharge. Based on this study; patients aged above 50 years, unemployed in occupation, patients who had a history of preoperative anemia, ASA IV physical status, emergency surgery, intraoperative blood loss greater than 500 ml, and hospital length of stay above two weeks were significantly associated with postoperative anemia CONCLUSIONS : Among the study participants, 49.6 % of the adult surgical patients developed postoperative anemia. Therefore; clinicians should be familiar with the risk factors of postoperative anemia to minimize complications and to improve the patient’s perioperative quality of life.
