“…There are different established ways of addressing this fault. Mostly, constructive measures are carried out, like a bubble trap or a bubble filter close to the restitution of the blood to the patient [2]. The other established way is to introduce additional sensors to the circulation.…”

In extracorporeal blood circulation intensive care treatments, the occurrence of gas within the circulation is one known major hazard. This gas volume can cause severe harm to the patient like infarctions. Consequently, within risk assessment for these treatments gas bubbles are usually addressed by either constructive or signal based approaches. All signal-based approaches do have in common that they need a sufficient amount of data to be parameterized. These data can only be acquired in animal trials or laboratory experiments, as they could result in harm to patients. Hence, we designed a mock loop, which is automatically able to create annotated data of gas bubbles injected into an extracorporeal circulation. We were able to run this setup with a periodicity of 15 seconds, which results in 240 annotated measurements per hour. For the evaluation, we created 1095 bubbles of varying sizes (0.3 to 0.5 ml). The elaborated setup enables us to produce a great amount of annotated data, which is shown to be comparable to manually generated data in a convenient and fully automated manner.

“…Quando comparada a utilização do FMEA versus HFMEA para analisar riscos em setor da área da saúde, identificouse que há diferenças entre os dois métodos e apontou o HFMEA como mais simples e adequado para a aplicação nesta área, além de ressaltar a efetividade da Matriz de Pontuação de Risco e da Árvore de Decisão utilizadas neste método (Rah, Manger, Yock, Kim, 2016). Ainda, a utilização do método é um importante aliado para justificar as possíveis alterações que devem ocorrer, relacionados ao processo de trabalho (Overdevest, Hees, Lagerburg, Kloeze, Straten, 2014).…”

Objetivo: Analisar a reação álgica produzida pela aplicação da vacina Hepatite B na região ventroglútea em recém-nascidos e verificar sua relação com o sexo, a idade gestacional de nascimento e as características antropométricas. Metodologia: Estudo quantitativo, exploratório, de corte transversal, realizado no alojamento conjunto de um hospital universitário com amostra de 121 recém-nascidos. Para a avaliação da reação álgica, utilizou-se a Neonatal Pain Scale, a frequência cardíaca e o tempo de choro. Os escores produzidos pela escala foram associados às variáveis: sexo, horas de vida, idade gestacional e medidas antropométricas. Durante a análise dos dados, calculou-se as medidas: mínimo, máximo, mediana, média, desvio padrão, coeficiente de Correlação de Spearmam e utilizou-se o teste Wilcoxon, Mann Whitney e Kruskal Wallis. Resultados: A maioria dos recém-nascidos apresentou dor, com um escore médio pela Neonatal Pain Scale de 2,87 (ausência de dor) antes e 6,14 (presença de dor) durante o procedimento, sendo estatisticamente significativo (p<0,0001). Identificou-se uma correlação positiva fraca entre a frequência cardíaca e os escores da escala de Neonatal Pain Scale e uma correlação forte deste último com o tempo de choro. Conclusão: A reação álgica é uma realidade mesmo com o uso da região ventroglútea e não há variação conforme as características estudadas dos recém-nascidos.

Background/Aims Prospective risk management is a necessary measure when managing and providing the right response to a healthcare system error. This article provides an improved model of the Healthcare Failure Mode and Effect Analysis model, which aims to reduce errors in the operating room and improve on the major defects found in the Healthcare Failure Mode and Effect Analysis model. Methods The improved model presented in this descriptive mixed-methods article was examined in 2015 on selective processes in total knee replacement in Shahid Madani Hospital's operating rooms in Karaj, Iran. Data were collected through clinical observations, individual and group interviews, and collaborative conversations with the study team. Results A total of 8 activities and 15 modes of failure were identified in 5 selection processes in total knee replacement surgery. The identified modes of failure were given scores. Ultimately, 15 potential causes and 17 measures were proposed for 12 failures. The failure of the ‘unmanaged nurse or the anaesthesia technician in the operating rooms’ had the highest priority, and ‘chest leads’ and a ‘blood pressure cuff placed in the incorrect position’ had the lowest priority. Conclusion The improved model better reported the risk priorities of failures in 9 out of 12 modes. It was also able to resolve major defects in the Healthcare Failure Mode and Effect Analysis model and produce more reliable results.
