ABSTRACT
Background: Although alcohol-based surgical hand preparation offers potential advantages over the traditional surgical scrubbing technique, implementing it may be challenging due to resistance of surgeons in changing their practice. We aimed to implement alcohol-based surgical hand preparation in the hospital setting evaluating the impact of that on the quality and duration of the procedure, as well as on the prevention of surgical site infections. Methods: A quasi-experimental study conducted at a tertiary-care university hospital from April 01 to November 01, 2017. Participants were cardiac and orthopedic surgical teams (n = 56) and patients operated by them (n = 231). Intervention consisted of making alcohol-based handrub available in the operating room, convincing and training surgical teams for using it, promoting direct observation of surgical hand preparation, and providing aggregated feedback on the quality of the preparation. The primary study outcome was the quality of the surgical hand preparation, inferred by the compliance with each one of the steps predicted in the World Health Organization (WHO) technique, evaluated through direct observation. Secondary study outcome was the patient's individual probability of developing surgical site infection in both study periods. We used the Wilcoxon for paired samples and McNemar's test to assess the primary study outcome and we build a logistic regression model to assess the secondary outcome. Results: We observed 534 surgical hand preparation events. Among 33 participants with full data available for both study periods, we observed full compliance with all the steps predicted in the WHO technique in 0.03% (1/33) of them in the pre-intervention period and in 36.36% (12/33) of them in the intervention period (OR:12.0, 95% CI: 2. 4-59.2, p = 0.002). Compared to the pre-intervention period, the intervention reduced the duration of the preparation (4.8 min vs 2.7 min, respectively; p < 0.001). The individual risk of developing a surgical site infection did not significantly change between the pre-intervention and the intervention phase (Adjusted RR = 0.66; 95% CI 0. 16-2.70, p = 0.563). Conclusion: Our results demonstrate that, when compared to the traditional surgical scrub, alcohol-based surgical hand preparation improves the quality and reduces the duration of the preparation, being at least equally effective for the prevention of surgical site infections.

Modelo do Estudo: Estudo de Caso. Objetivo do Estudo: O presente trabalho visou estudar o processo de compras e programação de materiais de um hospital público de ensino de nível terciário e analisar os perfis de itens de materiais de consumo faltantes em determinado período, com a finalidade de identificar como ferramentas de gestão de materiais podem ajudar na definição de políticas de compras e estoque. Metodologia: O estudo foi elaborado com base em análises qualitativas e quantitativas. As primeiras foram feitas por meio de coleta de dados relativos ao entendimento dos processos e estrutura interna da Divisão de Materiais do Hospital através de observação e entrevistas semi estruturadas entre o período de setembro a novembro de 2013. A relação dos itens faltantes em 2012 e 2013 foi obtida através do sistema de informação da instituição e a partir destes dados foram feitas as análises quantitativas dos perfis destes itens segundo as classificações ABC e VEN (ou XYZ). Resultado: Os resultados apontam que dos 8.595 itens de materiais de consumo do Hospital apenas 5% em quantidade são classificados como A na curva ABC, no entanto tais itens correspondem a 42% em valores. Já os itens vitais representam 49% do valor e 46% em termos de quantidade. Quando analisadas em conjunto, as duas curvas apontam que a maioria das quantidades de materiais de consumo do Hospital são classificados como vitais da curva C (36,35%) e os itens não essenciais da curva A representam tanto em valor como em quantidade a menor parcela de materiais. O perfil dos itens faltantes em 2012 e 2013 são semelhantes,o maior índice de faltas está nos itens vitais da curva C e a menor nos itens não essenciais da curva...
Model Study: Case Study. Purpose of the Study: This study aims to explore the purchasing materials process in a tertiary teaching hospital and analyze the missing items profiles in a given period in order to identify how materials management tools can help optimizing purchasing and inventory policies. Methodology: The study was based on qualitative and quantitative analyses. The first was made by means of collecting data to understand both processes and internal structure of the Materials Division through observation and semi-structured interviews between September-November 2013. A list of missing items in 2012 and 2013 was obtained from system information in order to analyze the profiles of these items according to the ABC and VEN (or XYZ) ratings. Results: The results show that out of 8,595 items of consumable materials, only 5 % in volume are classified as A in ABC curve, however such items correspond to 42 % in value. On the other hand, vital items represent 49 % on value and 46 % in terms of quantity. When analyzed together, the two curves show that most quantities of consumables materials are classified as vital from the C curve (36.35%) where as non-essential items from the A curve represent both in value and in volume the smallest amount portion of materials. The missing items profile in 2012 and 2013 were similar, the highest rate of faults is from vital and C curve materials and the smaller, of nonessentials of the A curve...
