RESUMO

BACKGROUND: There is limited evidence from antimicrobial stewardship programmes in less-resourced settings. This study aimed to improve the quality of antibacterial prescriptions by mitigating overuse and promoting the use of narrow-spectrum agents in intensive care units (ICUs) in a middle-income country. METHODS: We established a quality improvement collaborative (QIC) model involving nine Argentine ICUs over 11 months with a 16-week baseline period (BP) and a 32-week implementation period (IP). Our intervention package included audits and feedback on antibacterial use, facility-specific treatment guidelines, antibacterial timeouts, pharmacy-based interventions and education. The intervention was delivered in two learning sessions with three action periods along with coaching support and basic quality improvement training. RESULTS: We included 912 patients, 357 in BP and 555 in IP. The latter had higher APACHE II (17 (95% CI: 12 to 21) vs 15 (95% CI: 11 to 20), p=0.036), SOFA scores (6 (95% CI: 4 to 9) vs 5 (95% CI: 3 to 8), p=0.006), renal failure (41.6% vs 33.1%, p=0.009), sepsis (36.1% vs 31.6%, p<0.001) and septic shock (40.0% vs 33.8%, p<0.001). The days of antibacterial therapy (DOT) were similar between the groups (change in the slope from BP to IP 28.1 (95% CI: -17.4 to 73.5), p=0.2405). There were no differences in the antibacterial defined daily dose (DDD) between the groups (change in the slope from BP to IP 43.9, (95% CI: -12.3 to 100.0), p=0.1413).The rate of antibacterial de-escalation based on microbiological culture was higher during the IP (62.0% vs 45.3%, p<0.001).The infection prevention control (IPC) assessment framework was increased in eight ICUs. CONCLUSION: Implementing an antimicrobial stewardship program in ICUs in a middle-income country via a QIC demonstrated success in improving antibacterial de-escalation based on microbiological culture results, but not on DOT or DDD. In addition, eight out of nine ICUs improved their IPC Assessment Framework Score.

RESUMO

BACKGROUND: The demand for healthcare services during the COVID-19 pandemic was excessive for less-resourced settings, with intensive care units (ICUs) taking the heaviest toll. OBJECTIVE: The aim was to achieve adequate personal protective equipment (PPE) use in 90% of patient encounters, to reach 90% compliance with objectives of patient flow (OPF) and to provide emotional support tools to 90% of healthcare workers (HCWs). METHODS: We conducted a quasi-experimental study with an interrupted time-series design in 14 ICUs in Argentina. We randomly selected adult critically ill patients admitted from July 2020 to July 2021 and active HCWs in the same period. We implemented a quality improvement collaborative (QIC) with a baseline phase (BP) and an intervention phase (IP). The QIC included learning sessions, periods of action and improvement cycles (plan-do-study-act) virtually coached by experts via platform web-based activities. The main study outcomes encompassed the following elements: proper utilisation of PPE, compliance with nine specific OPF using daily goal sheets through direct observations and utilisation of a web-based tool for tracking emotional well-being among HCWs. RESULTS: We collected 7341 observations of PPE use (977 in BP and 6364 in IP) with an improvement in adequate use from 58.4% to 71.9% (RR 1.2, 95% CI 1.17 to 1.29, p<0.001). We observed 7428 patient encounters to evaluate compliance with 9 OPF (879 in BP and 6549 in IP) with an improvement in compliance from 53.9% to 67% (RR 1.24, 95% CI 1.17 to 1.32, p<0.001). The results showed that HCWs did not use the support tool for self-mental health evaluation as much as expected. CONCLUSION: A QIC was effective in improving healthcare processes and adequate PPE use, even in the context of a pandemic, indicating the possibility of expanding QIC networks nationwide to improve overall healthcare delivery. The limited reception of emotional support tools requires further analyses.

RESUMO

Abstract This study aimed to assess the impact of the implementation of a rapid multiplex molecular FilmArray Respiratory Panel (FRP) on the medical management of immunocompromised patients from a community general hospital. We conducted a single-center, retrospective, and before-after study. Two periods were evaluated: before the implementation of the FRP (pre-FRP) from April 2017 to May 2018 and after the implementation of the FRP (post-FRP) from January to July 2019. The inclusion criteria were immunocompromised patients over 18 years of age with suspected acute respiratory illness tested by conventional diagnostic meth-ods (pre-FRP) or the FilmArray™ Respiratory Panel v1.7 (post-FRP). A total of 142 patients were included, 64 patients in the pre-FRP and 78 patients in the post-FRP. The positive detec-tion rate was significantly higher in the post-FRP (63% vs. 10%, p <0.01). There were more patients receiving antimicrobial treatment in the pre-FRP compared with the post-FRP period (94% vs. 68%, p <0.01). A decrease in beta-lactam (89% vs. 61%, p <0.01) and macrolide (44% vs. 13%, p < 0.01) prescriptions were observed in the post-FRP. No differences were observed in oseltamivir use (22% vs. 13%, p = 0.14), changes in antimicrobial treatment, hospital admission rate, days-reduction in droplet isolation precautions, hospital length of stay (LOS), admission to intensive care unit (ICU), LOS in ICU, treatment failure and 30-day mortality. The implementa-tion of the FRP impacted patient care by improving diagnostic yield and optimizing antimicrobial treatment in immunocompromised adult patients.

Resumen El objetivo de este estudio fue evaluar el impacto de la implementación del panel respiratorio FilmArray® (FRP), un sistema automatizado de PCR multiplex, en el estándar de cuidado de pacientes adultos inmunocomprometidos en un hospital general. Es un estudio retrospectivo de un único centro con diseno antes/después. Los periodos evaluados fueron abril 2017-mayo 2018, previo a la implementación del FRP (pre-FRP), y enero 2019-julio 2019, luego de la implementación (post-FRP). Los criterios de inclusión fueron pacientes mayores de 18 años inmunocomprometidos con sospecha de infección respiratoria aguda a los que se les realizó, en pre-FRP, diagnóstico por métodos convencionales, y en post-FRP, el panel respiratorio FRP versión 1.7. Se incluyeron un total de 142 pacientes, 64 en pre-FRP y 78 en post-FRP. La tasa de positividad fue significativamente mayor en post-FRP frente a pre-FRP (63 vs. 10%, p<0,01). Hubo más pacientes con tratamiento antimicrobiano en pre-FRP que en post-FRP (94 vs. 68%, p <0,01). En pre-FRP hubo más pacientes tratados con betalactámicos (89 vs. 61%, p <0,01) y macrólidos (44 vs. 13%, p < 0,01). No se observaron diferencias significativas en el uso de oseltamivir (22 vs. 13%, p = 0,14), cambios en los tratamientos, número de hospitalizaciones, uso de aislamientos, duración de la estadía hospitalaria, ingreso a la unidad de cuidados intensivos, estadía en dicha unidad, falla de tratamiento y mortalidad a 30 días. El uso de FRP contribuyó a la atención del paciente mejorando el rendimiento diagnóstico y optimizando la terapia antimicrobiana en pacientes adultos inmunocomprometidos.

RESUMO

INTRODUCTION: Cystic fibrosis (CF) is the most frequent recessive autosomal disorder in the Caucasian population. It is caused by mutations that result in a deficient or dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR) protein activity. Among CFTR modulators, potentiator compounds increase channel opening, whereas corrector compounds increase CFTR quantity in the cell surface. OBJECTIVE: To report real-life effects of a generic formulation of lumacaftor-ivacaftor use in patients with CF homozygous for the Phe508del CFTR mutation. PATIENTS AND METHODS: Clinical variables (body mass index [BMI], pulmonary exacerbations, sweat test, and pulmonary function) were analyzed in 30 CF patients homozygous for the Phe508del CFTR mutation, treated with lumacaftor-ivacaftor for 12 months, at the Respiratory Center of Hospital de Niños Ricardo Gutiérrez. These clinical variables were compared with those before the use of modulators. RESULTS: A total of 30 patients with CF homozygous for the Phe508del CFTR mutation receiving lumacaftor-ivacaftor therapy were included in this study. The median (interquartile range [IQR]) age at the start of treatment was 10.79 (7.08-14.05) years. Nineteen patients were male. Before treatment, median (IQR) sweat chloride concentration was 80 (72-92) mEq/L, and it had decreased to 74 (68-78) mEq/L (p = .05) 12 months after treatment. Median (IQR) BMI z-score improved from -0.33 (-0.86 to 0.21) to -0.13 (-0.66 to 0.54) (p = .003). A spirometry was performed in 28 of 30 patients. Median (IQR) ppFEV1 was 83.5 (71-91) before treatment and 86.5 (67-103) after treatment (p = .38), 73.3% of patients referred decreased sputum production and 40% reported improvement in their dyspnea at 12 months. Severe pulmonary exacerbations significantly decreased from 60% in the year before treatment, to 30% at 12 months after treatment (p = .037); 13 patients showed an improvement in their exacerbation rates, 2 showed an increased rate, and 15 showed no change. CONCLUSIONS: The use of a generic formulation of lumacaftor-ivacaftor in patients homozygous for the Phe508del CFTR mutation was associated with improvement in nutritional status and respiratory symptoms, and a significant reduction in severe pulmonary exacerbations.

Metodología: Estudio de tipo descriptivo observacional y retrospectivo, en el que se analizaron 1686 certificados de defunción por suicidio de hombres y mujeres en el departamento de Nariño, identificados en el Departamento Nacional Administrativo de Estadística. Resultados: En el periodo 2005-2019, se observaron 1212 suicidios en hombres y 474 en mujeres. Estas se suicidaron a edades más bajas que aquellos. El 50,5 % de los hombres habían cursado básica primaria, y el 46,0 % de las mujeres, básica secundaria. El mayor número de casos de suicidios en hombres y mujeres se presentaron en el área urbana (51,2 % y 45,1 % respectivamente). El envenenamiento fue el mecanismo de suicidio más utilizado por las mujeres (66,7 %), y para los hombres, el mayor porcentaje (41,7) correspondió al ahorcamiento. La tendencia anual de muertes por suicidio fue mayor en hombres que en mujeres. En aquellos, la tasa de suicidio se situó por encima de 4,5 suicidios por 100 000 habitantes, mientras que, en ellas, se mantuvo por debajo de 3,0. Conclusiones: Hubo un aumento en la tendencia de muertes en el periodo de tiempo analizado y el riesgo de morir por suicidio en el hombre fue 3,9 veces el riesgo de morir en una mujer. El estudio contempla importantes aspectos para ser abordados en la prevención del suicidio.

Objective: To identify the sex differences associated with the potential years of life lost due to suicide in the department of Nariño, from 2005 to 2019. Methodology: Descriptive, observational and retrospective study, in which 1686 death certificates by suicide of men and women in the department of Nariño, identified in the National Administrative Department of Statistics, were analyzed. Results: From 2005 to 2019, 1,212 suicide cases of men were observed and 474 of women. Women committed suicide at younger ages than men. 50.5% of the men had completed primary school, and 46.0% of the women, secondary school. The highest number of suicide cases of men and women occurred in the urban area (51.2% and 45.1% respectively). Poisoning was the suicide mechanism most used by women (66.7%), and for men, the highest percentage (41.7) corresponded to hanging. The annual trend of deaths by suicide was higher in men than in women. For men, the suicide rate was above 4.5 suicides per 100,000 inhabitants, while for women, it remained below 3.0. Conclusions: There was an increase in the trend of deaths in the period analyzed and the risk of dying by suicide in men was 3.9 times the risk of dying by suicide in women. The study contemplates important aspects to be addressed in suicide prevention.

RESUMO

Introducción: recientemente, se ha evidenciado una tendencia hacia estilos de vida y hábitos alimentarios saludables y un incremento de productos orientados para tal fin. Entre ellos se incluyen alimentos para veganos/vegetarianos, "naturales", aquellos que destacan la ausencia de aditivos o ingredientes de tipo "alérgenos". Estos productos envasados suelen presentar leyendas y/o logos que los caracterizan. El objetivo fue realizar un relevamiento de logos, sellos, frases en los rótulos de alimentos comerciales y analizar la información encontrada según la legislación vigente en Argentina. Materiales y Métodos: se relevaron al azar 151 alimentos comerciales en supermercados, dietéticas y páginas web de empresas (agosto-octubre de 2022). Los productos relevados fueron: farináceos (PF), bebidas vegetales (BV), análogos de cárnicos (AC), análogos de quesos (AQ) y otros. Los atributos buscados fueron veganos/vegetarianos (VV), natural/artesanal (NA), ausencia de aditivos (AA), ausencia de lactosa (ALA), ausencia de alérgenos (AAE). Resultados: el atributo VV se observó en el 68% de los productos relevados y prevaleció en los AC, PF y BV. El atributo NA se observó en 23% de los alimentos, principalmente en AC y PF. Para AA, que se presentó en 75% de los alimentos, los PF se destacaron. Los atributos ALA y AAE aparecieron en el 17% de los alimentos. Las BV fueron la categoría que más presentó el atributo ALA. En ellas se observó una alta prevalencia de AA y ALA. En los AC, el atributo que se destacó fue VV (92%). Dentro de PF, la mayor prevalencia fue del atributo AA (96%), seguido por VV (57%). En el grupo AQ, prevaleció el atributo VV (89%). Conclusiones: se observó una alta presencia de atributos en los rótulos, que en su mayoría carecen de una normativa nacional vigente que los avale. Ello se contrapone a la demanda del mercado actual y a consumidores más exigentes

Introduction: recently, there has been a trend towards healthy lifestyles and eating habits; therefore, there is an increase in products oriented for this purpose. Among these products we can find foods for vegans/vegetarians, "natural" foods, those that emphasize the absence of additives or "allergenic" type ingredients. These packaged products usually have legends and/or logos that characterize them. The objective was to carry out a survey of logos, seals and phrases in labels of commercial foods and analyze the information found according to current legislation in Argentina. Materials and Methods: 151 commercial foods were randomly surveyed in supermarkets, dietetics and company websites (August-October 2022). The surveyed products were: farinaceous (FP), vegetable drinks (VD), meat analogues (MA). , cheese analogues (CA) and others. The attributes sought were vegan/vegetarian (VV), natural/artisanal (NA), absence of additives (AA), absence of lactose (ALA), absence of allergens (AAE). Results: the VV attribute was observed in 68% of surveyed products and prevailed in MA, FP and VD. The NA attribute was observed in 23% of the foods, mainly in MA and PF. For AA, which was present in 75% of the food products analyzed, the FPs stood out. In the case of ALA and AAE attributes, they appeared in 17% of the foods. VD was the category that presented the ALA attribute in the highest percentage. A high prevalence of AA and ALA was observed in them. In the MA, the attribute that stood out was VV (92%). Within FP, the highest prevalence was of the AA attribute (96%), followed by VV (57%). In the CA group, the VV attribute prevailed (89%). Conclusions: a large presence of attributes was observed in the labels, which mostly lack current national regulations that endorse them. This contrasts with the demands of the current market and with demanding consumers

RESUMO

INTRODUCCIÓN: Al inicio de la pandemia de COVID-19, las empresas mineras, debieron implementar sistemas de gestión para prevenir transmisión de SARS-CoV-2. OBJETIVO: Describir los resultados iniciales de la estrategia multimodal para la prevención de COVID-19, en una faena minera. MATERIALES Y MÉTODOS: Estudio descriptivo, de corte transversal. Se estructuró un sistema de gestión que consideró medidas administrativas, ambientales, tamizaje de riesgos y gestión de casos de riesgo al interior de la empresa. Análisis de datos con estadística descriptiva. RESULTADOS: Las medidas administrativas se tradujeron en que 8.116 (34%) trabajadores de la faena fueron suspendidos de sus labores habituales. El tamizaje de riesgo antes del ingreso a la faena identificó 450 casos sospechosos que fueron derivados a su domicilio. En el procedimiento de gestión de casos 1.073 personas fueron clasificadas en algunos de los grupos de riesgo. Se detectaron 10 casos de trabajadores con RPC positiva, siendo que 50% fue asintomático; en los sintomáticos, los síntomas más frecuentes fueron: tos (60%) y cefalea (40%). CONCLUSIONES: Estos resultados, dan luces sobre la importancia de implementar una estrategia multimodal, adaptada a la realidad local de una empresa de la gran minería, para prevenir la transmisión de SARS-CoV-2.

BACKGROUND: Mining companies must implement management systems dedicated to health and safety at work to prevent the transmission of SARS-CoV-2 among their workers, however, the literature on this is scarce. AIM: To describe a multimodal strategy for the management of health and safety at work, to address the risk of COVID-19 in large mining. METHODS: Descriptive cross-sectional study, carried out in a large mining company. A management system was structured that considered administrative measures, of an environmental nature, risk screening, and management of risk cases within the company. The data analysis was done using descriptive statistics. RESULTS: The administrative measures resulted in 8,116 (34%) workers at the site being suspended from their usual work. Risk screening before entering the site identified 450 suspected cases that were referred to their home. In the case management procedure, 1,073 people were classified in some of the risk groups. 10 cases of workers with PCR were detected in the follow-up period. Environmental measures were not very sensitive. CONCLUSIONS: These results shed light on the importance of implementing a multimodal strategy, adapted to the local reality, in preventing the spread of SARS-CoV-2 in the period under study, at the mining site intervened.

RESUMO

In spite of the low frequency of COVID-19 associated bacterial coinfections, the rate of empiric antibiotic use varies between 70% and 90%. The primary objective of this study was to evaluate the impact of an antimicrobial stewardship program (ASP) on COVID-19 patients. The study design was an interrupted time series, assessing prevalence of antibiotic use, adequacy of treatment and antimicrobial consumption in adult patients hospitalized with COVID before the COVID-ASP implementation in June 2020, and on three subsequent periods (P2 in August 2020, P3 in October 2020 and P4 in June 2021). One hundred and one patients were included. Moderate and severe disease was more frequent in P2, P3, and P4 periods (p < 0.001). After the implementation we observed a significant reduction on ATM use (61% vs. 41% vs. 31.1% vs. 8.1%, p < 0.001), and macrolid combination therapy (17.3% vs. 19.2% vs. 10.8% vs. 1.4%, p = 0.03), and an increase of adequate use (37.5% vs. 46.9% vs. 69.9% vs. 66.6%, p = 0.039). Antimicrobial consumption by period in days of therapy (DOT)/1000 patient-day was 347.9 vs. 272.8 vs. 134.29 vs. 43.6 (p <0.001). We did not find any difference in intensive care unit transfer or mortality. COVID-ASP implementation was an effective strategy to reduce antimicrobial consumption and optimize antibiotic indications without affecting morbidity or mortality.

A pesar de la baja frecuencia de coinfecciones bacterianas asociadas al COVID-19, la tasa de uso de antibióticos (ATB) empíricos varía entre 70 y 90%. El objetivo primario del estudio fue evaluar el impacto de la implementación de un programa de optimización de antimicrobianos en pacientes con COVID-19 (PROA-COVID). Se realizó un estudio prospectivo de serie de tiempo interrumpida. Se evaluó la prevalencia, adecuación y consumo de ATB en adultos internados con COVID previo a la implementación del PROA-COVID (P1, junio 2020) y en tres períodos posteriores (P2 en agosto 2020, P3 en octubre 2020 y P4 en junio 2021). Se incluyeron 301 pacientes. Las formas clínicas moderadas-graves fueron más frecuentes en los P2, 3 y 4 (p < 0.001). La implementación del programa mostró una disminución significativa del uso de ATB (61% vs. 41% vs. 31.1% vs. 8.1%, p < 0.001), de la indicación de tratamiento combinado con macrólidos (17.3% vs. 19.2% vs. 10.8% vs. 1.4%, p = 0.03) y aumento del uso adecuado (37.5% vs. 46.9% vs. 69.9% vs. 66.6%, p = 0.039). El consumo de ATB en DDT (días de tratamiento) totales/1000 días paciente fue: 347.9 vs. 272.8 vs. 134.3 vs. 43.6 (p < 0.001). No hubo diferencias significativas en el pase a unidades de cuidados críticos ni en la mortalidad. La implementación del PROA-COVID fue una estrategia efectiva para reducir el uso de antibióticos y optimizar sus indicaciones sin impacto en la morbimortalidad.
