Influence of the leukoreduction moment of blood components on the clinical outcomes of transfused patients in the emergency department.

OBJECTIVES: to investigate the influence of the leukoreduction moment (preor post-storage) of blood components on the clinical outcomes of patients transfused in the emergency department. METHODS: retrospective cohort study of patients aged 18 years or older who received preor post-storage leukoreduced red blood cell or platelet concentrate in the emergency department and remained in the institution for more than 24 hours. A generalized mixed-effects model was applied in the analyses. RESULTS: in a sample of 373 patients (63.27% male, mean age 54.83) and 643 transfusions (69.98% red blood cell), it was identified that the leukoreduction moment influenced the length of hospital stay (p<0.009), but was not dependent on the transfused blood component (p=0.124). The leukoreduction moment had no effect (p>0.050) on transfusion reactions, healthcare-associated infections, or mortality. CONCLUSIONS: patients who received pre-storage leukoreduced blood components in the emergency department had a shorter length of hospital stay.

RESUMEN Objetivos: verificar la influencia del momento de la leucorreducción (pre o post-almacenamiento) de hemocomponentes en la evolución clínica de pacientes transfundidos en la emergencia. Métodos: cohorte retrospectiva de pacientes de 18 años o más que recibieron, en el departamento de emergencia, concentrado de eritrocitos o plaquetas leucorreducidas pre o post-almacenamiento. Se aplicó un modelo de efectos mixtos generalizado en los análisis. Resultados: en la muestra de 373 pacientes (63,27% hombres, edad media 54,83) y 643 transfusiones (69,98% concentrado de eritrocitos) se identificó que el momento de la leucorreducción influyó en el tiempo de internación hospitalaria de los pacientes (p<0,009), pero no dependió del hemocomponente transfundido (p=0,124). El momento de la leucorreducción no tuvo efecto (p>0,050) en las variables de reacción transfusional, infección relacionada con la atención de la salud y óbito. Conclusiones: los pacientes que recibieron hemocomponentes leucorreducidos pre-almacenamiento en la emergencia presentaron un menor tiempo de internación hospitalaria.

RESUMO Objetivos: verificar a influência do momento da leucorredução (pré ou pós-armazenamento) de hemocomponentes na evolução clínica de pacientes transfundidos na emergência. Métodos: coorte retrospectiva de pacientes com idade igual ou maior de 18 anos que receberam, no departamento de emergência, concentrado de hemácias ou plaquetas leucorreduzidas pré ou pós-armazenamento. Modelo de efeitos mistos generalizado foi aplicado nas análises. Resultados: na amostra de 373 pacientes (63,27% homens, idade média 54,83) e 643 transfusões (69,98% concentrado de hemácias) foi identificado que o momento da leucorredução influenciou o tempo de internação hospitalar dos pacientes (p<0,009), porém não foi dependente do hemocomponente transfundido (p=0,124). O momento da leucorredução não teve efeito (p>0,050) nas variáveis reação transfusional, infecção relacionada à assistência à saúde e óbito. Conclusões: pacientes que receberam na emergência hemocomponente leucorreduzido pré-armazenamento apresentaram menor tempo de internação hospitalar.

Effect of post-storage filters vs. pre-storage filters for leukoreduction of blood components on clinical outcomes: a systematic review protocol.

OBJECTIVE: This review will synthesize the best available evidence on the effectiveness of leukocyte reduction by comparing post-storage and pre-storage filters. The review will consider the following clinical outcomes: transfusion reactions, bacterial infection, length of stay, and mortality. INTRODUCTION: Transfusion is a relevant therapy, but it is not risk-free. Leukocyte reduction can be performed either by apheresis or by pre- or post-storage filters in order to reduce the risk of transfusion reactions, transmission of some diseases, alloimmunization, and platelet refractoriness. It can also reduce the length of hospital stay and the use of antibiotics. INCLUSION CRITERIA: Studies comparing the transfusion of leukocyte reduction through post-storage filters with pre-storage filters in patients of any age who received a transfusion and the clinical outcomes resulting from the transfusion will be considered for inclusion. Studies in Portuguese, English, and Spanish will be considered, with no publication time limit. METHODS: The research sources will include MEDLINE (PubMed), CINAHL (EBSCO), PsycINFO, Scopus, The Cochrane Library, Web of Science Core Collection, Embase, LILACS, and gray literature sources. The selection of titles and abstracts will be carried out by two independent reviewers, and the critical evaluation of the studies will be based on JBI tools. The data of interest for the review question will be extracted using JBI SUMARI. A narrative synthesis will be performed as will a meta-analysis and risk assessment of publication bias, if possible. SYSTEMATIC REVIEW REGISTRATION: PROSPERO: CRD42020192202.

Patient safety in organizational culture as perceived by leaderships of hospital institutions with different types of administration.

OBJECTIVE: To identify the perceptions of leaderships toward patient safety culture dimensions in the routine of hospitals with different administrative profiles: government, social and private organizations, and make correlations among participating institutions regarding dimensions of patient safety culture used. METHOD: A quantitative cross-sectional study that used the Self Assessment Questionnaire 30 translated into Portuguese. The data were processed by analysis of variance (ANOVA) in addition to descriptive statistics, with statistical significance set at p-value ≤ 0.05. RESULTS: According to the participants' perceptions, the significant dimensions of patient safety culture were 'patient safety climate' and 'organizational learning', with 81% explanatory power. Mean scores showed that among private organizations, higher values were attributed to statements; however, the correlation between dimensions was stronger among government hospitals. CONCLUSION: Different hospital organizations present distinct values for each dimension of patient safety culture and their investigation enables professionals to identify which dimensions need to be introduced or improved to increase patient safety. OBJETIVO: Identificar percepções das lideranças sobre as dimensões da cultura de segurança do paciente no cotidiano de hospitais de diferentes perfis administrativos: públicos, organizações sociais e privados, e realizar correlação entre as instituições participantes, de acordo com as dimensões da cultura de segurança do paciente utilizadas. MÉTODO: Estudo transversal de aspecto quantitativo obtido por meio da aplicação do instrumento Self Assessment Questionnaire 30, traduzido para a língua portuguesa. Os dados foram tratados com análise de variância (ANOVA), além das estatísticas descritivas, considerando como de significância estatística valores de p-valor ≤ 0,05. RESULTADOS: Segundo a percepção dos participantes do estudo, as dimensões significativas para a cultura de segurança do paciente foram Ambiente de Segurança do Paciente e Aprendizado Organizacional, com poder explicativo de 81%. A média de respostas obtidas evidenciou que nas organizações privadas houve maiores valores atribuídos às questões, porém a correlação entre as dimensões foi mais forte nas organizações públicas. CONCLUSÃO: As dimensões da cultura de segurança do paciente têm valores distintos nas diferentes organizações hospitalares e a sua investigação possibilita identificar quais necessitam ser introduzidas ou aprimoradas para maior segurança do paciente.
