Analysis of the Relationship between blood donor knowledge level and blood donor service management to the low number of blood donors at the guido Valadares National Hospital Blood Bank in 2019

Blood is the most essential part of human life because it is a means of transportation in the human body that can save someone from death. According to WHO Facts in 2019, blood collected globally per year only reached 117.4 million blood donors. As found in the serology and blood transfusion report from the RSNGV Blood Bank in 2017, explains that the blood that was successfully collected during the reporting period amounted to 3704 units of safe and ready-to-transfuse blood, of which only 21% was obtained from volunteer donors and 79% came from family donors. In the comparison between blood donors and blood transfusion needs, it was also found that the number of blood donors was less than the amount of blood transfused in 2017, the difference reaching 8-12%. The purpose of this study was to analyze the relationship between the level of knowledge and service management system to the lack of blood donors at the Guido Valadares National Hospital. The type of research is quantitative analytical with a Cross-Sectional survey approach, with a sample of 77 people. Data were obtained by interview and then analyzed univariately and bivariate using Pearson product-moment correlation analysis. The results of univariate data analysis showed that the level of knowledge of blood donors in the poor category was 49.4%, around 50.6% of respondents stated that the blood donor service management system was poor and 59.7% were in the family blood donor category. While the results of bivariate data analysis with Pearson Product Moment correlation analysis showed that the calculated r value for the level of knowledge r = 0.281 was greater than the r table value of 0.189 P = value 0.013 <0.05, then the level of knowledge has a significant influence on the lack of donor numbers even though the level of relationship is very low, while the calculated r value for the management system shows a calculated r-value of -0.230 greater than r table 0.189, p = value 0.044 <0.05, then the donor service management system has a significant influence on the lack of voluntary blood donors even though the level of relationship is very low, namely -0.230. The conclusion of the statistical test data shows that the level of knowledge of blood donors and the blood donor service management system greatly affects the lack of blood donor numbers at the Guido Valadares National Hospital Blood Bank. So the advice that can be given is to increase public knowledge about the importance of blood donation activities and pay attention to the service system implemented, especially providing sufficient information to blood donors who will donate blood.
