[Multicenter study of adherence to guidelines on surgical prophylaxis and the determinants of non-adherence in ArgentinaEstudo multicêntrico sobre a adesão a diretrizes de profilaxia cirúrgica e seus determinantes na Argentina]. / Estudio multicéntrico de adherencia a guías de profilaxis quirúrgica y sus determinantes en Argentina.

OBJECTIVE: Evaluate the level of adherence to guidelines on surgical prophylaxis in health facilities in Argentina and the determinants of non-adherence. METHODS: Cross-sectional multicenter study in 35 centers in Argentina. The level of adherence to guidelines and the forms of non-adherence were determined and these were compared based on the characteristics of the indicated antibiotic, anesthesiologist, surgery, and facility, as well as patient age. An adjusted logistic regression model was used. RESULTS: A total of 1,083 surgical procedures were reviewed. Adherence to guidelines was 67%. The most frequent forms of non-adherence were: incorrect antibiotic (28.9%), unnecessary prophylaxis (25.5%), and prolonged prophylaxis (24.4%). Adherence to guidelines was higher in persons under 18 years of age (84.9% compared to 65.5%, p < 0.001). According to the type of health coverage (social welfare, private insurance, public coverage, or community coverage), adherence was 33.3%, 64.4%, 78.8%, and 83.3%, respectively; p < 0.001. According to population (maternal and child, pediatric, specific pathologies, and general pathologies), adherence was 97.9%, 97.2%, 89.4%, and 63.2%, respectively; p < 0.001. Adherence was highest in neurosurgery (91.1%), obstetrics (82.4%), and cardiovascular surgery (72.9%), and lowest in otorhinolaryngology (47.8%), ophthalmology (50%), and urology (55.9%) (p < 0.001). The adjusted analysis showed the highest adherence to guidelines in persons under 18 (odds ratio [OR]: 4.97; 95% confidence interval [CI 95]: 1.13-21.80); emergency surgery (OR: 2.18; CI 95: 1.11-4.26); and public, private, and community facilities (OR: 9.35; CI 95: 3.85-22.70). Adherence was also higher in facilities for maternal and child care and specific pathologies (OR: 10.52; CI 95, 1.30-85.12), cardiovascular surgery, neurosurgery, obstetrics (OR: 2.73; CI 95: 1.55-4.78), and facilities with programs to optimize the use of antimicrobial drugs (OR 1.95; CI 95, 1.10-3.45). CONCLUSIONS: Adherence to guidelines was 67%. Incorrect, unnecessary, and prolonged use of antibiotics were the most frequent forms of non-adherence. Adherence was higher with younger patients, where programs exist to optimize the use of antimicrobial drugs, where there is private or public health coverage, with the pediatric population, for specific pathologies, in emergency surgery, and in certain specialties.

OBJETIVO: Avaliar o nível de adesão às diretrizes (AD) de profilaxia cirúrgica em instituições de saúde da Argentina e os determinantes da não adesão (NA). MÉTODOS: Estudo multicêntrico transversal realizado em 35 centros na Argentina. Determinamos o nível de AD e as formas de NA, comparados segundo as características das seguintes variáveis: indicação antibiótica, anestesista, cirurgia, instituição e idade do paciente. Aplicamos um modelo de regressão logística ajustado. RESULTADOS: Revisamos um total de 1083 procedimentos cirúrgicos. A taxa de AD foi de 67%. As formas mais frequentes de NA foram: antibiótico incorreto (28,9%), profilaxia desnecessária (25,5%) e profilaxia prolongada (24,4%). A AD foi mais elevada em pacientes com menos de 18 anos (84,9% vs. 65,5%, p<0,001); também houve variações segundo o tipo de instituição (instituição de seguridade social, privada, pública ou comunitária, com adesão de 33,3%, 64,4%, 78,8% e 83,3%, respectivamente; p<0,001) e segundo a população (materno-infantil, pediátrica, com patologia específica ou geral, com adesão de 97,9%, 97,2%, 89,4% e 63,2%, respectivamente; p<0,001). A AD foi maior em neurocirurgia (91,1%), obstetrícia (82,4%) e cirurgia cardiovascular (72,9%) e menor em otorrinolaringologia (47,8%), oftalmologia (50%) e urologia (55,9%) (p<0,001). A análise ajustada mostrou uma AD mais elevada em pacientes com menos de 18 anos (odds ratio [OR]: 4,97, intervalo de confiança de 95% [IC95%]: 1,13-21,80), em cirurgias de emergência (OR: 2,18, IC95%: 1,11-4,26) e em instituições públicas, privadas ou comunitárias (OR: 9,35, IC95%: 3,85-22,70). A AD também foi superior em instituições para população materno-infantil ou para populações específicas (OR: 10,52; IC95%: 1,30-85,12), cirurgia cardiovascular, neurocirurgia, obstetrícia (OR: 2,73; IC95%: 1,55-4,78) e em instituições com programas para a otimização do uso de antimicrobianos (OR: 1,95; IC95%: 1,10-3,45). CONCLUSÕES: A AD foi de 67%; as formas mais frequentes de NA foram o uso incorreto, desnecessário e prolongado de antibióticos. A AD foi maior em pacientes mais jovens, em instituições com programas para a otimização do uso de antimicrobianos, em instituições privadas ou públicas e em populações pediátricas ou específicas, nos procedimentos cirúrgicos de emergência e em certas especialidades.

[Program for the prevention of Carbapenemase-Producing Enterobacteria in critical units in Argentina during the COVID-19 pandemic]. / Programa de prevención de enterobacterias productoras de carbapenemasas en unidades críticas durante la pandemia COVID-19 en Argentina.

INTRODUCTION: The problem of carbapenemase-producing Enterobacteriaceae (CPE) was exacerbated by the COVID-19 pandemic in countries with a previous high incidence, such as Argentina. This study describes the development and results of a CPE prevention program, mainly carbapenemase-producing Klebsiellas (KPC), in three critical units of two public hospitals during 6 months of the pandemic. METHODS: The objective was to reduce the incidence of KPC in clinical and colonization samples. This quasi-experimental study was based on a cycle of improvement and implementation of three measures: hand hygiene, environmental hygiene, and periodic surveillance with rectal swabs. RESULTS: Regarding the measures, all the units optimized active surveillance, and two of these also improved hand and environmental hygiene. Comparing the pre- and post-intervention periods in the three units, no significant change was observed in the rate of KPC positive clinical samples. KPC colonization was significantly reduced in two units (unit 2: 51.6-18.5 p 0.0004, unit 3: 62.5-5.2 p < 0.0000001). All units showed a downtrend in both rates towards the end of the study. CONCLUSION: Containing or reducing the advance of the KPC in our region is possible even in difficult scenarios such as the pandemic. More studies are needed in low- and middle-income countries to demonstrate the impact of KPC prevention programs in these situations.

Introducción: La problemática de las enterobacterias productoras de carbapenemasas (EPC) se exacerbó con la pandemia por COVID-19 en países con una incidencia previa elevada, como la Argentina. Este estudio describe el desarrollo y resultados de un programa de prevención de EPC, fundamentalmente Klebsiellas productoras de carbapenemasas (KPC), en tres unidades críticas de dos hospitales públicos durante 6 meses de la pandemia. Métodos: El objetivo fue reducir la incidencia de KPC en muestras clínicas y de colonización. Este estudio, quasi experimental, se basó en un ciclo de mejora e implementación de tres medidas: higiene de manos, higiene ambiental y vigilancia periódica con hisopados rectales. Resultados: Respecto a las medidas, todas las unidades mejoraron la vigilancia activa y dos de estas tuvieron además mejoría en la higiene de manos e higiene ambiental. Comparando los períodos pre y post intervención en las tres unidades no se observaron cambios significativos en la tasa de muestras clínicas KPC positivas. Se logró disminuir en forma significativa la colonización por KPC en dos unidades (unidad 2: 51.6-18.5 p 0.0004, unidad 3: 62.5-5.2 p < 0.0000001). Todas las unidades mostraron hacia el final del estudio una tendencia al descenso en ambas tasas. Conclusión: Contener o reducir el avance de KPC en nuestra región es posible incluso en escenarios difíciles como el de la pandemia. Se necesitan más estudios en países de ingresos bajos y medianos, para demostrar el impacto de los programas de prevención de KPC en estas situaciones.

The COVID-19 pandemic has had an impact on public health and the global economy. The objective of this document was to update, according to the available evidence, the management of some basic elements in the Infection Control Programs (PCI) and the daily care of patients. As a result: 1. The routine use of the N95 masks is not recommended for the care of suspected or confirmed COVID-19 patients. Available data indicates that SARS-CoV-2 has spread primarily like most other common respiratory viruses, through droplet and contact transmission. In certain situations, personto-person transmission is described through the airway, observed in poorly ventilated environments, and while the individual carried out actions of greater potential transmission 2. The limited reuse and decontamination methods of N95 masks are accepted under safe and effective prot ocols in the context of limited resources. 3. The isolation of patients with COVID-19 can be lifted under a strategy based on the clinic, individual risk factors and time of evolution of the disease. 4. PCR control is not required in confirmed cases to determine epidemiological discharge. 5. Current evidence shows that there is a possibility of reinfection although its diagnosis is difficult. 6. The measurement of antibodies has a specific role in prevalence studies, diagnosis of multisystemic inflammatory syndrome and a picture compatible with negative PCR after the 7th. day.

El objetivo de este documento fue actualizar según la evidencia disponible, el manejo de algunos elementos básicos en los Programas de Control de Infecciones (PCI) y la atención diaria de los pacientes. Como resultado: 1. No se recomienda el uso rutinario de barbijo N95 para la atención de pacientes sospechosos o confirmados de COVID-19. Datos disponibles indican que el SARS-CoV-2 se ha propagado principalmente a través de la transmisión por gotas y contacto. En ciertas situaciones se describen contagios de persona a persona a través de la vía respiratoria aérea observadas en ambientes poco ventilados, y mientras el individuo realizaba acciones de mayor potencialidad de transmisión. 2. Se acepta el reúso limitado y métodos de decontaminación de máscaras/barbijos N95 bajo protocolos seguros y eficaces en el contexto de recursos limitados. 3. Se puede levantar el aislamiento de pacientes confirmados de COVID-19 bajo una estrategia basada en la clínica, factores de riesgo individuales y tiempo de evolución de la enfermedad. 4. No se requiere PCR control en casos confirmados para determinar el alta epidemiológica. 5. La evidencia actual demuestra que existe la posibilidad de reinfección, aunque su diagnóstico es dificultoso. 6.

Aceptación de la vacunación contra la COVID-19 durante la primera ola pandémica en Perú / Acceptance of COVID-19 vaccination during the first pandemic wave in Peru

Señor editor: El exceso de muertes debido a la COVID-19 en Perú durante el 2020fueunodelosmáselevadosdelmundo,esto probablemente favorecido por la fragilidad del sistema salud y los determinantes sociales de este país. Si bien una de las principales estrategias para mitigar el impacto de esta enfermedad es la vacunación masiva, la falta de aceptación de la vacuna por parte de la población peruana podría ser uno de los mayores desafíos para lograr dicho objetivo.

Mr. Editor: The excess of deaths due to COVID-19 in Peru during 2020 was one of the highest in the world, probably favored by the fragility of the health system and the social determinants of this country. Although one of the main strategies to mitigate the impact of this disease is mass vaccination, the lack of acceptance of the vaccine by the Peruvian population could be one of the biggest challenges to achieve this goal.

[RESUMEN]. Objetivo. Evaluar el nivel de adherencia a las guías de profilaxis quirúrgica (AG) en instituciones de salud de Argentina y los determinantes de la falta de adherencia (NA). Métodos. Estudio multicéntrico de corte transversal en 35 centros de Argentina. Se determinaron el nivel de AG y las formas de NA y se comparó según características de la indicación antibiótica, anestesista, cirugía, institución y edad del paciente. Se ajustó un modelo de regresión logística. Resultados. Se revisaron 1 083 procedimientos quirúrgicos (PQ). La AG fue de 67%. Las formas más frecuentes de NA fueron: antibiótico incorrecto (28,9%), profilaxis innecesaria (25,5%) y profilaxis prolongada (24,4%). La AG fue mayor en menores de 18 años (84,9% frente a 65,5%, P < 0,001); según la dependencia (obra social, privada, pública o comunitaria) fue de 33,3%, 64,4%, 78,8% y 83,3%, respectivamente; P < 0,001) y según la población (maternoinfantil, pediátrica, con patología específica y general) fue de 97,9%, 97,2%, 89,4% y 63,2%, respectivamente; P < 0,001). La AG fue mayor en neurocirugía (91,1%), obstetricia (82,4%) y cirugía cardiovascular (CCV) (72,9%) y menor en otorrinolaringología (ORL) (47,8%), oftalmología (50%) y urología (55,9%) (P < 0,001). El análisis ajustado mostró mayor AG en menores de 18 años (odds ratio [OR]: 4,97; intervalo de confianza de 95% [IC95]: 1,13-21,80), cirugía de urgencia (OR: 2,18; IC95: 1,11-4,26) e institución pública, privada o de comunidad (OR: 9,35; IC95: 3,85-22,70).
