RESUMO

Resumen: Introducción: El diferimiento quirúrgico desde el inicio de la pandemia COVID-19 representa un riesgo para la salud de los pacientes y un reto para las instituciones sanitarias. La métrica de indicadores de productividad en quirófano, como la tasa de diferimiento quirúrgico, nos brindará información para planear estrategias basadas en evidencia científica que nos permitan mejorar la calidad de la atención. Objetivo: Determinar la tasa de diferimiento quirúrgico durante la pandemia COVID-19. Material y métodos: Se realizó un estudio, retrospectivo, descriptivo y transversal en el que se analizaron 297 pacientes cuyas cirugías fueron diferidas durante el período comprendido del 11 de marzo de 2020 al 10 de marzo de 2021. Para el análisis de variables se efectuó estadística descriptiva, utilizando medidas de tendencia central y dispersión, frecuencias simples y proporciones. Adicionalmente se realizó un diagrama de Pareto. La información fue procesada con SPSS v-25.0. Resultados: La proporción de diferimiento fue de 7.34%; 20.92% de las causas fueron atribuidas al paciente, 31.65% a causas médicas y 47.49% fueron logístico-administrativas. Conclusión: Las causas de diferimiento quirúrgico establecidas son evitables y revelan fracasos en los procesos logístico-administrativos que requieren planes de mejora continua.

Abstract: Introduction: Surgical deferral since the beginning of the COVID-19 pandemic represents a risk to the health of patients and a challenge for health institutions. The metric of productivity indicators in the operating room, such as the surgical deferral rate, will provide us with information to plan strategies based on scientific evidence that allow us to improve the quality of care. Objective: To determine the surgical deferral rate during the COVID-19 pandemic. Material and methods: A retrospective, descriptive and cross-sectional study was carried out in which 297 patients whose surgeries were deferred during the period from March 11, 2020 to March 10, 2021 were analyzed. Descriptive statistics were employed, using measures of central tendency and dispersion, simple frequencies and proportions. Additionally, a Pareto diagram was made. The information was processed with SPSS v-25.0. Results: The deferral rate was 7.34%. 20.92% of the causes were attributed to the patient, 31.65% to medical causes and 47.49% logistic-administrative. Conclusion: The established causes of surgical deferral are avoidable and reveal failures in the logistical-administrative processes that require continuous improvement plans.

RESUMO

Objective: The efficient use of wards intended for elective surgeries is essential to resolve cases on the surgical waiting list. This study aims to estimate the efficiency of ward use in the Chilean public health system between 2018 and 2021. Methods: The design was an ecological study. Section A.21 of the database constructed by the monthly statistical summaries that each public health network facility reported to the Ministry of Health between 2018 and 2021 was analyzed. Data from subsections A, E and F were extracted: ward staffing, total elective surgeries by specialty, number and causes of suspension of elective surgeries. Then, the surgical performance during working hours and the percentage of hourly occupancy for a working day was estimated. Additionally, an analysis was made by region with data from 2021. Results: The percentage of elective wards in use ranged from 81.1% to 94.1%, while those enabled for those staffing ranged from 70.5% to 90.4% during 2018 and 2021. The total number of surgeries was highest in 2019 (n = 416 339), but for 2018, 2020, and 2021 it ranged from 259 000 to 297 000. Suspensions varied between 10.8% (2019) and 6.9% (2021), with the leading cause being patient-related. When analyzing the number of cases canceled monthly by facility, we saw that the leading cause was trade union-related. The maximum throughput of a ward intended for elective surgery was reached in 2019 and was 2.5 surgeries; in 2018, 2020 and 2021, the throughput borders on two surgeries per ward enabled for elective surgery. The percentage of ward time occupied during working hours by contract day varies between 80.7% (2018) and 56.8% (2020). Conclusions: All the parameters found and estimated in this study show that there is an inefficient utilization of operating rooms in Chilean public healthcare facilities.

Objetivo: El uso eficiente de pabellones destinados a cirugías electivas es fundamental para resolver patologías en lista de espera quirúrgica. El objetivo general de este estudio es estimar la eficiencia del uso de pabellones en el sistema de salud público de Chile entre los años 2018 y 2021. Métodos: El diseño fue un estudio ecológico. Se analizó la Sección A.21 de la base de datos construida por los resúmenes estadísticos mensuales que cada establecimiento de la red de salud pública reportó al Ministerio de Salud de Chile entre 2018 y 2021. Se extrajeron los datos de la subsección A, E y F: dotación de pabellones, total de cirugías electivas por especialidad, número y causas de suspensión de cirugías electivas. Luego se estimó el rendimiento quirúrgico en horario hábil y el porcentaje de ocupación horaria respecto de una jornada laboral. Adicionalmente, se hizo un análisis por región con datos de 2021. Resultados: El porcentaje de pabellones electivos respecto de los en dotación varió entre 81,1 y 94,1%; mientras que los habilitados respecto de los en dotación varió entre 70,5 y 90,4% durante 2018 y 2021. El número total de cirugías fue más alto en 2019 (n = 416 339), pero en 2018, 2020 y 2021 variaron entre 259 y 297 mil cirugías. Las suspensiones varían entre 10,8 (2019) y 6,9%w(2021), siendo la principal causa de suspensión atribuida al "paciente". Al analizar la cantidad de pacientes suspendidos mensualmente por institución, se observa que la principal causa es "gremial". El rendimiento máximo de un pabellón destinado a cirugía electiva se alcanzó en 2019 y fue de 2,5 cirugías; mientras que en 2018, 2020 y 2021 el rendimiento bordea las dos cirugías por pabellón habilitado para cirugía electiva. El porcentaje de tiempo de pabellón ocupado en horario hábil respecto a una jornada de contrato varía entre 80,7 (2018) y 56,8% (2020). Conclusiones: Todos los parámetros encontrados y estimados en este estudio muestran que el uso de pabellones en el sistema público de Chile es ineficiente.

RESUMO

BACKGROUND: Unexpected cancelation of scheduled total joint arthroplasty (TJA) procedures creates patient distress and disruption for the clinical team. The purpose of this study is to identify the etiology and fate of cancelations for scheduled TJAs. METHODS: A consecutive series of 11,670 patients at a single institution from 2013 to 2017 was reviewed in March 2020. All patients who were scheduled for a primary total hip arthroplasty or total knee arthroplasty and subsequently canceled were identified. The etiology of cancelation and time to rescheduling were recorded. RESULTS: Of the 505 (4.3%) canceled patients, 209 (42%) were due to medical reasons. Three hundred ninety-one patients (77%) eventually underwent their procedure at a mean delay of 165 days (19-1908). Only 53 (25%) patients canceled for a medical reason underwent further diagnostic or therapeutic intervention for their medical condition. When compared to patient-driven cancelations, those canceled for medical reasons had a higher mean Charlson Comorbidity Index (0.82 vs 0.39, P < .001), were canceled closer to the scheduled surgery date (8.55 vs 18.1 days, P < .001), and were more likely to eventually undergo surgery (86% vs 73%, P = .004). CONCLUSION: Canceled elective TJA surgeries are most often due to a medical concern, however only a minority of these patients undergo intervention for that medical condition. To minimize the risk of cancelation, healthcare providers may consider early referral of medically complex patients to the patient's primary care physician. After cancelation, patients should have a clearly defined path to return to the operative schedule to prevent further delays.

RESUMO

OBJECTIVE: To analyze the factors attributable to the cancellation of surgeries of a third level health institution in the city of Valledupar, Cesar / Colombia (2017-2018). MATERIAL AND METHODS: Descriptive, retrospective, cross-sectional study. Data from the hospital surgical unit adverse case file were collected for 6 surgical specialties. RESULTS: They showed that in 2017 there was a surgical suspension of 4% of the total of scheduled surgeries that were (3339), for 2018 the rate was 3% with a total of scheduled surgeries (1733). The reason for the suspension for both periods was the factor related to the patient's adverse conditions with 45.9 and 38.5% respectively. The specialty most affected for these cases was the specialty of general surgery with the same percentage value in both periods of 4%. CONCLUSION: The results give us an idea of the factors present for the cancellation of scheduled surgeries and the need to apply measures to guarantee patient safety.

RESUMO

Resumen Introducción: Las suspensiones quirúrgicas constituyen una problemática compleja en el ámbito de la administración de pabellones, que afecta tanto a pacientes como al personal de pabellón, y que compromete la eficiencia financiera de las instituciones de salud. Existe escasa información acerca de la incidencia y características de las suspensiones quirúrgicas en nuestro país. Objetivo: Caracterizar las suspensiones quirúrgicas en un centro académico chileno, describiendo su incidencia global y por especialidad. Materiales y Métodos: Se incluyó información recopilada de manera prospectiva acerca de la programación y actividad de pabellón, y de una cohorte de pacientes suspendidos de cirugía entre el 1 de enero de 2016 y el 20 de mayo de 2017. Para calcular el porcentaje de suspensiones se utilizaron 3 grupos en base a 6 períodos de 4 semanas. Se aplicó la transformación de doble arcoseno de Freeman-Turkey y el test-t de Student. Resultados: Durante el período del estudio se programaron 11.398 cirugías, de ellas 492 fueron suspendidas. La incidencia de suspensiones de los 3 períodos fue de 4,38% (IC 95% de 3,78% a 5,01%), 4,15% (IC 95% de 3,51% a 4,85%) y 4,10% (IC 95% de 3,50% a 4,74%) respectivamente. Al menos en un 57% de los casos la principal causa de suspensión se identificó como un cambio en la condición médica del paciente. Discusión y Conclusiones: Nuestros resultados muestran, de manera consistente, que las suspensiones se encuentran entre un 3% y un 5%, lo que está dentro de los estándares internacionales, y pueden ser utilizados como un "benchmarking" para comparaciones a nivel nacional.

Introduction: Surgical cancellations are a complex problem in the field of Operating Room Management, affecting patients, staff, including surgeons and anesthetists, and compromising the finances of health institutions. The available information about the incidence and characteristics of surgical cancellations in our country are scarce. Objective: The aim of this article is to characterize the surgical cancellations in a Chilean academic center, describing its global incidence and by specialty. Materials and Methods: Prospective information on surgical schedule and Operating Room activity was included in this cohort study of surgical case cancellations occurring from January 1, 2016 through May 20, 2017. To calculate the percentage of cancellations, 3 groups were used based on 6 periods of 4 weeks. The Freeman-Turkey double-arcsine transformation and Student's t-test were applied. Results: During the study period, 11,398 surgeries were programmed, of which 492 were cancelled. The incidence of cancellations for the 3 periods was 4.38% (95% CI 3.78% to 5.01%), 4.15% (95% CI 3.51% to 4.85%) and 4.10% (95% CI of 3.50% to 4.74%) respectively. In at least 57% of cases the main identifiable cause of cancellation was a change in the patient's medical condition. Discussion and Conclusions: Our results consistently show that the cancellation rates range between 3% and 5%, which is within international standards, and can be used as benchmarking for comparisons at a national level.

RESUMO

The study aims to chart the development of the willingness to forgive among adolescents, as a function of seven situational factors: Possibility of revenge, cancellation of harmful consequences, encouragement to forgive from parents and/or from close friends, social proximity with the offender, intent to harm, and presence of apologies. The participants were presented with 16 stories in which an adolescent committed a harmful act against another one. Each participant was asked to rate the degree of personal willingness to forgive in each case on a continuous scale. The effect of the cancellation of consequences factor was the strongest one, and it was stronger among younger adolescents than among older adolescents. The effect of the intent factor was the second strongest factor, and it was stronger among older adolescents than among younger adolescents. The effect of the encouragement factors was moderate (encouragement by friends), or small (encouragement by parents), and no age difference was observed. The effects of the revenge, apologies, and social proximity factors were always weak. An additive-type combination process was observed in each age group.

El objetivo del estudio fue describir el desarrollo de la voluntad para perdonar en adolescentes, como función de siete factores situacionales: posibilidad de venganza, anulación de consecuencias perjudiciales, disposición a perdonar a los padres o amigos cercanos, proximidad social con el delincuente, intención de daño y ofrecimiento de excusas. A los participantes se les presentaron 16 historias donde un adolescente había cometido un acto perjudicial contra otro. Caso por caso, se pidió a cada participante valorar en una escala continua el grado de voluntad para olvidar. El efecto de la anulación del factor de consecuencias fue el más fuerte, y mayor entre adolescentes jóvenes en comparación con los de más edad. El efecto del factor intención se ubicó en segundo lugar, siendo más fuerte entre los adolescentes mayores que entre los más jóvenes. El efecto de los factores de disposición a perdonar fue moderado (amigos) o pequeño (padres), y no se encontró diferencia en cuanto a la edad. En todos los casos, los efectos de la venganza, las disculpas y los factores sociales de proximidad fueron débiles. En cada grupo de edad, se observó un proceso de combinación de tipo aditivo.

RESUMO

O presente artigo traz dados de normatização do Teste de Atenção por Cancelamento (TAC). Participaram do estudo 524 sujeitos, com idades entre sete e 16 anos, estudantes do ensino fundamental das redes pública e privada da cidade de Natal/RN. Foram analisadas as diferenças de desempenho dos estudantes em função do tipo de escola, sexo e faixa etária. Verificou-se que as variáveis: nível de escolaridade e tipo de escola mostraram-se estatisticamente significativas (p < 0,05), enquanto a variável sexo não apresentou relevância para diferenciação de desempenho dos estudantes. Em termos de acurácia e velocidade em tarefas que avaliam a seletividade e alternância, constatou-se aumento significativo no desempenho dos estudantes nas três primeiras séries do ensino fundamental e estabilização dos resultados nos três últimos anos, o que aponta para estabelecimento de platô no desenvolvimento atencional. O TAC apresentou sensibilidade para a detecção de aspectos neurodesenvolvimentais e características socioculturais do funcionamento cognitivo humano.

This paper presents normative data concerning Attention by Cancelling Test (ACT). A group of 524 subjects aged between seven and 16 years and registered in elementary private and public schools in Natal/RN/Brazil took part in this research. Simultaneously differences were analyzed in students performance according to the type of school, gender and age. It was found that educational level and school type were statistically significant for students performance (p < 0.05), while gender did not show relevant effect. A statistically significant improvement in accuracy and speed in selectivity and alternance tasks was verified in students of 1st to 3rd primary school years. On the other hand, performance of students during the last three primary school years showed a clear stabilization, which leads to think in a developmental plateau in attention processes. Data issued from ACT showed sensibility in order to evaluate both neurodevelopmental and sociocultural aspects of human cognitive functioning.

En este artículo se presentan los datos normativos para el Test de Atención por Cancelación (TAC). El estudio incluyó a 524 sujetos, con edades comprendidas entre los siete y dieciséis años, estudiantes de escuelas primarias pública y privadas de la ciudad de Natal/RN. Se analizaron las diferencias del desempeño de los estudiantes en función del tipo de escuela, el género y la edad. Se verificó que las siguientes variables: nivel de educación y tipo de escuela fueron estadísticamente significativas (p < 0,05), mientras que la variable de género no presentó importancia a la diferenciación del desempeño de los estudiantes. En términos de precisión y velocidad en las tareas que evalúan la selectividad y la alternativa, se produjo un aumento significativo en el rendimiento de los estudiantes en los tres primeros grados de la escuela primaria y estabilización de los resultados en los últimos tres años, lo que apunta a establecer meseta en el desarrollo atencional. El TAC presentó sensibilidad para la detección de los aspectos de neurodesarrollo y en las características socio-culturales del funcionamiento cognitivo humano.

RESUMO

Os testes de cancelamento são classicamente utilizados em avaliações neuropsicológicas de atenção e velocidade psicomotora, com a tarefa tradicional de riscar alvos entre distratores. O Teste de Cancelamento dos Sinos, reconhecido internacionalmente por sua contribuição diagnóstica de heminegligência visual, foi desenvolvido com a tarefa de circular todos os sinos o mais rápido possível. Buscou-se verificar se há diferenças de desempenho entre duas versões de aplicação - sinos círculo e traço - em uma mesma amostra de 88 adultos neurologicamente saudáveis, de 19 a 75 anos, com no mínimo cinco anos de escolaridade. Eles foram avaliados na mesma sessão com as duas versões alternadamente. Os escores de acurácia e tempo foram comparados pelo teste Wilcoxon. O tempo da tarefa de riscar foi menor que o tempo da tarefa de circular. Assim, as duas versões não parecem ser totalmente equivalentes. Sugerem-se estudos para padronizar a versão sinos traço, assim como para caracterizar amostras clínicas, principalmente aquelas com ocorrência de heminegligência como sequela.

Cancellation tests are traditionally used in neuropsychological assessment of attention and psychomotor speed, with the traditional task of marking targets. The Bells Test, internationally acknowledged for its contribution to the diagnosis of visual hemineglect, was developed with the task of circling all the bells as quick as possible. This paper aimed at verifying whether there are differences in performance between two versions of application - bells with circles and bells with straight lines - in the same sample consisting of 88 neurologically healthy adults from 19 to 75 years of age, with at least 5 years of formal education. The sample was evaluated in the same session with the two versions in an alternative manner. Accuracy and time scores were compared by the Wilcoxon test. The performance time of the marking task was lower than in the circular version. Thus, the two versions do not seem to be totally equivalent. Studies are suggested to standardize the bells with straight lines version, as well as to describe clinical samples, especially those with hemineglect as a sequelae.
