Gunshot Wounds Cause Significant Mortality, Blood Utilization, and Health Care Costs in the U.S.

July 6, 2021
Half of the world’s civilian firearms are owned by individuals in the United States. The U.S. also leads all high-income countries for gunshot wound (GSW)-related deaths, yet little is known about the blood utilization patterns in GSW victims. Researchers analyzed data from the 2016-2017 National Inpatient Sample and National Emergency Department Sample, which included 58,815 weighted inpatient hospitalizations from GSWs and 168,315 weighted emergency department visits due to GSWs.

Reducing Red Cell Use for Patients with Sickle Cell Disease during a Pandemic

June 30, 2021
Since March 2020, the COVID-19 pandemic has strained blood inventories, so researchers at one Philadelphia hospital implemented new measures to reduce blood use in patients with sickle cell disease (SCD). Fifty patients (mean age, 23.5 years [range: 9 to 44 years]) with SCD requiring chronic red cell exchanges every 3 to 5 weeks were followed for 6 months from March 2020 to September 2020 to determine if two new measures reduced blood usage.

Tracking HIV Drug Resistance and Subtypes in Blood Donors

June 22, 2021
The risk of HIV transmission from blood transfusion is low (0.16 to 0.49 per million transfusions) but is still possible due to the viral window period during which newly acquired infections are not detected by diagnostic screening methods. In Poland, the frequency of HIV-positive blood donors and donations per 100,000 was 6.6 and 3.3, respectively. Therefore, constant hemovigilance is needed to identify pre-seroconversion infections, but samples can also be used to study HIV genetic diversity and drug resistance patterns. [Read More]
