Efficiency in the alarm signs of immature cells reported from the automated hematology analyzer of the “Beckman Coulter 600“ equipment with the revision of the peripheral plate in adult patients, Hospital Nacional Hipólito Unanue, El Agustino Peru, December 2019 - February 2020

The objective was to determine the efficiency of immature cell alarms reported by the automated hematological analyzer in the "Beckman Coulter 600" with peripheral smear review in adult patients at the National Hipólito Unanue Hospital from December 2019 to February 2020. A total of 489 reports of immature leukocytes were evaluated. The efficiency, sensitivity, specificity, positive and negative predictive values, as well as the Kappa concordance index, were calculated. An efficiency of 95.3%, sensitivity of 70.0%, specificity of 95.8%, positive predictive value of 25.9%, and negative predictive value of 99.4% were found. The Kappa concordance index was 0.36. The efficiency level of the immature cell alarms in the central laboratory, reported by the Beckman Coulter equipment at the National Hipólito Unanue Hospital, was 95.3%. The sensitivity and specificity of the alarms of the Beckman Coulter automated equipment were 70.0% and 95.8%, respectively. The positive and negative predictive values of the alarms were 25.9% and 99.4%. The degree of concordance between the immature cell alarms of the automated hematological analyzer and the peripheral smear was 0.36, classified as mild.

Systematic Review: Effect of Leukoreduction as a Preventive and Therapeutic Measure for Diseases
(Universidad Privada Norbert Wiener, 1905-07-09) Chavez Jaime, Liz Pamela; Herencia Torres, Victor Reynaldo
Objective: To determine the effect of leucoreduction as a preventive and therapeutic measure for diseases. Methods: A bibliographic search was conducted in electronic databases (PubMed, Babelmesh, Tripdatabase, and Google Scholar), publications, and theses from February 2011 to January 2015, addressing topics related to transfusion medicine: leucoreduction as a preventive and therapeutic measure for diseases. Results: Seven qualitative, descriptive, cross-sectional articles were used to assess the effect of leucoreduction as a preventive and therapeutic measure for diseases. Conclusions: It is concluded that there is no clear evidence to accept or reject leucoreduction as a preventive and therapeutic measure for diseases. However, it is considered an alternative that should be implemented according to the type of patients and pathology that is susceptible to treatment.
