Red blood cell disorders (RBCDs) are conditions that affect red blood cells, the most abundant cells in blood that bring oxygen from the lung to the cells throughout the body. To characterize incidence of RBCDs over a period of 7 years from 2006 to 2012, we used the Nationwide Inpatient Sample (NIS), the largest all-payer inpatient care database in the United States. Using domain analysis, we determined the short-term trend in nationwide discharges, length of stay (LOS), total charges (TOTCHG). We also analyzed gender and age distribution over the period of interest. We found an increasing trend of RBCD admissions from 0.71 % in 2006 to 0.92 % in 2012, and a decreasing trend of average LOS from 4.02 days in 2006 to 3.74 days in 2012. There are significantly more females than males suffering from RBCDs, roughly 60 % to 40 %, a ratio stable over the years. Gender-wise age distribution analysis showed that females are likely to suffer from RBCDs at ages peaking around at 22, 46 and 80, while males were more likely at ages 22 and 85. The top disorder was sickle cell anemia, about 20 % of all RBCDs.
