Abstract

An adequate and reliable supply of blood and blood components is becoming an increasing public health concern. Over the past decade, researchers have indicated a continued decline in the collection of blood products. An insufficient blood supply may present a risk to both patients and reserves for emergencies and disasters. The purpose of this quantitative, cross-sectional study was to determine whether gender, age group, ethnicity, year, serological tests, and discard factors were associated with the availability of the donated blood supply throughout the New Orleans region. The donated blood supply chain model guided this study. Secondary data were retrieved from The Blood Center of New Orleans, Louisiana. A simple random sample technique was used to select the sample, consisting of 286,625 allogeneic blood donors. Bivariate logistic regression and multiple logistic regression were used to analyze data collected between 2008 and 2017. The bivariate logistic regression showed a statistically significant association (p = .000) between gender (OR = .760; 95% CI .753 – .767), age group (OR = 1.554; 95% CI 1.522 – 1.588), ethnicity (OR = .635; 95% CI .627 – .643), year (OR = .713; 95% CI .696 – .731), and available blood. Similarly, the multiple logistic regression also revealed a statistically significant association (p = .000) between gender (OR = .796; 95% CI .789 – .804), age group (OR = 1.426; 95% CI 1.395 – 1.458), ethnicity (OR = .672; 95% CI .664 – .681), year (OR = .726; 95% CI .708 – .744), and available blood. The knowledge presented in this study promotes positive social change by guiding blood center practitioners on ways to improve current work practices to increase the available donated blood supply and maintain a satisfactory blood inventory.
