Objective: To reduce diagnostic blood loss by using small volume tubes for routine laboratory testing throughout the hospital, as blood loss from laboratory testing can be substantial for patients and may lead to hospital-acquired anemia., Patients and Methods: Diagnostic blood loss was evaluated in hospitalized patients between April 1, 2017, and June 1, 2018. The preintervention, during intervention, and postintervention mean diagnostic blood loss per hospitalized patient was compared across the floors and for each type of tube for hematology, basic metabolic panel, and coagulation tests. Mean hemoglobin levels, blood transfusions per hospitalized patient, and percent redraws were also compared., Results: The total volume of blood drawn for all the 3 tests decreased across each implementation phase; however, only patients admitted to the transplant and critical care (T/CC) units had increased hemoglobin levels. In addition, there was a significant reduction in transfusions across implementation phases. The incidence risk ratio for transfusion reduced even more in patients admitted to the T/CC units. Finally, there was no significant difference in the overall percent redraws across all the units., Conclusion: The use of small volume tubes in exchange for standard sized tubes markedly decreased diagnostic blood loss by 25.7% in all the units and 22.9% in the T/CC units. Also, the number of transfusions decreased across units, with the greatest decrease in the T/CC units. An increase in mean hemoglobin levels was observed specifically in patients admitted to the T/CC units, with no corresponding change in percent redraws across all the units., (© 2020 Mayo Foundation for Medical Education and Research.

Background: Increasing use of glucose meters in hospitals has increased opportunities for infection transmission that have not been quantitatively assessed or managed., Methods: Before-and-after study of the effects of augmentation of glucose meter inventory and of assignment of glucose meters to individual patients on the sequential use of glucose meters on different patients in a 214-bed hospital., Results: During October 2008, 11,665 measurements were performed using 38 glucose meters on 803 patients. A total of 9,302 tests (79.7%) was performed sequentially within 24 hours on different patients. From October 28 through November 27, 2009, the glucose meter inventory on 3 high-use units glucose meters was increased (from 22 to 87) with meters assigned to individual patients; on 4 low-use units, glucose meter inventory was increased (from 16 to 28) without assignment to individual patients. Sequential glucose meter use on different patients within 24 hours decreased by 95.1% on high-use units and increased by 17% on low-use units., Conclusion: Use of glucose meters was associated with a high number of opportunities to transmit infections, and those opportunities were reduced only when glucose meters were assigned to individual patients. Recent guidance from the Centers for Disease Control and Prevention and the US Food and Drug Administration to assign glucose meters to individual persons whenever possible is relevant to inpatient care., (Copyright © 2011 Association for Professionals in Infection Control and Epidemiology, Inc.
