Vaso-occlusive pain crisis is a debilitating complication of sickle cell disease (SCD) and it is the most common cause of hospitalization among these individuals. We studied the inpatient outcomes among patients admitted with sickle cell crisis based on the timing of red blood cell transfusion. In this retrospective study, we used the United States National Inpatient Sample (NIS) data for the year 2019, to identify adult patients hospitalized with the principal diagnosis of sickle cell crisis who received simple red blood cell transfusion during their hospitalization. Patients were divided into two groups. Those who received simple red cell transfusion within 24 hours of admission were classified as early transfusion. After adjusting for confounders, the mean adjusted length of stay for patients with early transfusion was significantly lower than those who received a late blood transfusion by 3.51 days (p-value < 0.001) along with a decrease in mean adjusted hospitalization charges and cost, by 25,487 and 4,505 United States Dollar (USD) respectively. The early red cell transfusion was also associated with a decrease in inpatient mortality, demonstrated by an adjusted odds ratio (aOR) of 0.19 (p-value 0.036), and a reduction in in-hospital sepsis, with an aOR of 0.28 (p-value < 0.001), however, no statistically significant difference was found between the two groups regarding acute respiratory failure requiring intubation, vasopressors requirement, acute kidney injury requiring dialysis and intensive care unit (ICU) admission. We recommend timely triage and reassessment to identify sickle cell crisis patients requiring blood transfusion. This intervention can notably affect the inpatient length of stay, resource utilization, and hospitalization outcomes.
