Health Care Simulation in Person and at a Distance: A Systematic Review.

ABSTRACT: Distance simulation is a method of health care training in which the learners and facilitators are in different physical locations. Although methods of distance simulation have existed in health care for decades, this approach to education became much more prevalent during the COVID-19 pandemic. This systematic review studies a subset of distance simulation that includes combined in-person and distance simulation elements, identified here as "mixed- distance simulation." A review of the distance simulation literature identified 10,929 articles. Screened by inclusion and exclusion criteria, 34 articles were ultimately included in this review. The findings of this review present positive and negative aspects of mixed-distance simulation formats, a description of the most frequent configurations related to delivery, terminology challenges, as well as future directions including the need for faculty development, methodological rigor, and reporting details.

Usefulness of the COVID-GRAM and CURB-65 scores for predicting severity in patients with COVID-19.

AIM: The aim of this study was to determine the usefulness of COVID-GRAM and CURB-65 scores as predictors of the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Caucasian patients. METHODS: This was a retrospective observational study including all adults with SARS-CoV-2 infection admitted to Hospital Universitario Marqués de Valdecilla from February to May 2020. Patients were stratified according to COVID-GRAM and CURB-65 scores as being at low-medium or high risk of critical illness. Univariate analysis, multivariate logistic regression models, receiver operating characteristic curve, and area under the curve (AUC) were calculated. RESULTS: A total of 523 patients were included (51.8% male, 48.2% female; mean age 65.63 years (standard deviation 17.89 years)), of whom 110 (21%) presented a critical illness (intensive care unit admission 10.3%, 30-day mortality 13.8%). According to the COVID-GRAM score, 122 (23.33%) patients were classified as high risk; 197 (37.7%) presented a CURB-65 score ≥2. A significantly greater proportion of patients with critical illness had a high COVID-GRAM score (64.5% vs 30.5%; P < 0.001). The COVID-GRAM score emerged as an independent predictor of critical illness (odds ratio 9.40, 95% confidence interval 5.51-16.04; P < 0.001), with an AUC of 0.779. A high COVID-GRAM score showed an AUC of 0.88 for the prediction of 30-day mortality, while a CURB-65 ≥2 showed an AUC of 0.83. CONCLUSIONS: The COVID-GRAM score may be a useful tool for evaluating the risk of critical illness in Caucasian patients with SARS-CoV-2 infection. The CURB-65 score could be considered as an alternative.

QuantiFERON-TB Gold In-Tube as a Confirmatory Test for Tuberculin Skin Test in Tuberculosis Contact Tracing: A Noninferiority Clinical Trial.

Background: Screening strategies based on interferon-γ release assays in tuberculosis contact tracing may reduce the need for preventive therapy without increasing subsequent active disease. Methods: We conducted an open-label, randomized trial to test the noninferiority of a 2-step strategy with the tuberculin skin test (TST) followed by QuantiFERON-TB Gold In-Tube (QFT-GIT) as a confirmatory test (the TST/QFT arm) to the standard TST-alone strategy (TST arm) for targeting preventive therapy in household contacts of patients with tuberculosis. Participants were followed for 24 months after randomization. The primary endpoint was the development of tuberculosis, with a noninferiority margin of 1.5 percentage points. Results: A total of 871 contacts were randomized. Four contacts in the TST arm and 2 in the TST/QFT arm developed tuberculosis. In the modified intention-to-treat analysis, this accounted for 0.99% in the TST arm and 0.51% in the TST/QFT arm (-0.48% difference; 97.5% confidence interval [CI], -1.86% to 0.90%); in the per-protocol analysis, the corresponding rates were 1.67% and 0.82% in the TST and TST/QFT arms, respectively (-0.85% difference; 97.5% CI, -3.14% to 1.43%). Of the 792 contacts analyzed, 65.3% in the TST arm and 42.2% in the TST/QFT arm were diagnosed with tuberculosis infection (23.1% difference; 95% CI, 16.4% to 30.0%). Conclusions: In low-incidence settings, screening household contacts with the TST and using QFT-GIT as a confirmatory test is not inferior to TST-alone for preventing active tuberculosis, allowing a safe reduction of preventive treatments.

Predictive ability of the Mini Nutritional Assessment Short Form (MNA-SF) in a free-living elderly population: a cross-sectional study.

BACKGROUND: Various scales have been used to perform a quick and first level nutritional assessment, and the MNA is one of the most used and recommended by experts in the elderly in all areas. This scale has a short form, the MNA-SF, revised and validated in 2009, which has two versions: the BMI-MNA-SF contains the first six items of the full scale including Body Mass Index while the CC-MNA-SF includes Calf Circumference instead of BMI. OBJECTIVE: To evaluate the predictive ability for nutritional status of the two versions of the MNA-SF against the MNA in free-living elderly in the province of Valencia. METHODS: Cross-sectional study of 660 free-living elderly in the province of Valencia selected in 12 community centres using stratified sampling by blocks. Inclusion criteria: being aged 65 or over, living at home, having functional autonomy, residing in the province of study for more than one year, regularly attending community centres and voluntarily wanting to take part. RESULTS: Of the 660 subjects studied, 319 were men (48.3%) and 341 (51.7%) women with a mean age of 74.3 years (SD = 6.6). In terms of nutritional assessment, using the BMI-MNA-SF and the CC-MNA-SF we found that 26.5% and 26.2% were at risk of malnutrition and 0.9% and 1.5% were malnourished respectively. With the full MNA, 23.3% were at risk of malnutrition. Spearman's rank correlation coefficients indicate a high association between the full MNA score and the MNA-SFs scores (BMI-MNA-SF: ρ = 0.78p < 0.001; CC-MNA-SF: ρ = 0.78p < 0.001). In addition we obtained a very high correlation between the two MNA-SFs (ρ = 0.96p < 0.001). We evaluated the agreement between the full MNA and the MNA-SFs classification in three nutritional categories (normal nutritional status, risk of malnutrition, malnutrition) with Cohen's kappa coefficients (BMI-MNA-SF: κ = 0.54p < 0.001; CC-MNA-SF: κ = 0.52p < 0.001). These values indicate moderate agreement with the full MNA. There is very good agreement between the BMI-MNA-SF and CC-MNA-SF (κ = 0.88p < 0.001). In order to determine the ability of both MNA-SFs to identify subjects not requiring any nutritional intervention, we considered the dichotomised categorisation of the full MNA and the MNA-SFs as "normal nutritional status" vs. "malnutrition and risk of malnutrition" Areas under the ROC curves using MNA as the gold standard indicate moderately high prognostic accuracy (BMI-MNA-SF: AUC = 0.88p < 0.001; CC-MNA-SF: AUC = 0.87 p < 0.001). Both versions of the MNA-SF showed similar sensitivity, specificity and diagnostic effectiveness (BMI-MNA-SF: 73.4%, 86.6%, 83.5%; CC-MNA-SF 73.4%, 86.2%, 83.2%). CONCLUSIONS: In its two versions the MNA-SF presents useful predictive ability against the MNA. The advantage of the CC-MNA-SF is that using it requires fewer resources and less time in primary care, although always the characteristics of the population must take into account to make the right decision based on the MNA-SF scales.

Papel de la bacteriobilia en las complicaciones postoperatorias / Role of bacteriobilia in postoperative complications

Introducción. Actualmente existe controversia respecto al impacto de la positividad de cultivos biliares en la tasa de morbilidad y mortalidad, y en la incidencia de readmisiones en pacientes con enfermedad biliar. El objetivo de este estudio fue evaluar el papel de la bacteriobilia en las infecciones postoperatorias, la mortalidad o el reingreso hospitalario en estos pacientes. Métodos. La información se obtuvo a partir de los cultivos de vía biliar de los pacientes intervenidos en el Hospital Universitario Marqués de Valdecilla (Santander, España) entre enero y diciembre de 2011. Se analizaron los datos clínicos, epidemiológicos y microbiológicos. Los pacientes fueron seguidos durante dos años. Resultados. Se incluyeron 152 pacientes (65% varones). La media de edad fue de 67 años (DE: 15 años). Los diagnósticos más frecuentes fueron colecistitis aguda (79%) y colangitis (8%). Se realizó colecistectomía laparoscópica en el 42% de los pacientes, colecistectomía abierta en el 45% y colecistostomía percutánea en el 8%. La bacteriobilia estaba presente en 83 pacientes (55%). Los microorganismos más frecuentemente aislados fueron Escherichia coli (31%), Enterococcus faecium (13%) y Klebsiella pneumoniae (13%). Los antibióticos iniciales fueron carbapenémicos en 62 pacientes (44%) y piperacilina-tazobactam en 28 pacientes (18%). Hubo 39 infecciones postoperatorias (26%) y 17 pacientes fallecieron durante el ingreso (11%). Se registraron 21 reingresos (14%). La bacteriobilia no fue un predictor estadísticamente significativo de complicaciones o reingreso hospitalario. Conclusiones. Los cultivos biliares intraoperatorios permitieron orientar la terapia antimicrobiana empírica y el tratamiento antibiótico apropiado; sin embargo no hubo correlación entre la bacteriobilia y las infecciones posoperatorias, la duración del ingreso, la mortalidad o los reingresos (AU)

Introduction. At present there is a controversy regarding the impact of positive bile cultures on morbidity and mortality rates, and on the incidence of readmissions in patients with biliar disease. The aim of this study was to evaluate the role of bacteriobilia in postoperatory infections, mortality or readmissions in these patients. Methods. The information was obtained from all patients with bile cultures admitted to Hospital Universitario Marqués de Valdecilla (Santander, Spain) from January to December 2011. Clinical, epidemiological and microbiological data and laboratory findings were analyzed. The patients were followed for two years. Results. One hundred and fifty-two patients (65% men) were included. Mean age was 67 years (SD= 15 years). The most frequent diagnoses were acute cholecystitis (79%) and cholangitis (8%). Laparoscopic cholecystectomy was performed in 42% of patients, open cholecystectomy in 45% and percutaneous cholecystostomy in 8%. Bacteriobilia was present in 83 patients (55%). The most frecuent microorganisms isolated were Escherichia coli (31%), Enterococcus faecium (13%) and Klebsiella pneumoniae (13%). The initial antimicrobial agent was a carbapenem in 62 patients (44%) and piperacillin-tazobactam in 28 (18%). There were 39 postoperative infections (26%), 21 readmissions (14%) and 17 patients died during admission (11%). The presence of microorganisms in bile cultures was not a statistically significant predictor of neither complications nor readmissions. Conclusions. Intra-operative bile cultures would allow guide early appropriate antibiotic treatment use in case of infection, or empiric antimicrobial therapy, however there was no correlation between bacteriobilia and postoperative infections, length of stay, mortality or readmissions (AU)

Six simple questions to detect malnutrition or malnutrition risk in elderly women.

UNLABELLED: Of the numerous instruments available to detect nutritional risk, the most widely used is the Mini Nutritional Assessment (MNA), but it takes 15-20 min to complete and its systematic administration in primary care units is not feasible in practice. We developed a tool to evaluate malnutrition risk that can be completed more rapidly using just clinical variables. Between 2008 and 2013, we conducted a cross-sectional study of 418 women aged ≥60 years from Mexico. Our outcome was positive MNA and our secondary variables included were: physical activity, diabetes mellitus, hypertension, educational level, dentition, psychological problems, living arrangements, history of falls, age and the number of tablets taken daily. The sample was divided randomly into two groups: construction and validation. Construction: a risk table was constructed to estimate the likelihood of the outcome, and risk groups were formed. VALIDATION: the area under the ROC curve (AUC) was calculated and we compared the expected and the observed outcomes. The following risk factors were identified: physical activity, hypertension, diabetes, dentition, psychological problems and living with the family. The AUC was 0.77 (95% CI [0.68-0.86], p < 0.001). No differences were found between the expected and the observed outcomes (p = 0.902). This study presents a new malnutrition screening test for use in elderly women. The test is based on six very simple, quick and easy-to-evaluate questions, enabling the MNA to be reserved for confirmation. However, it should be used with caution until validation studies have been performed in other geographical areas.

[Nutrition-related risk factors in autonomous non-institutionalized adult elderly people]. / Factores asociados al riesgo nutricional en adultos mayores autónomos no institucionalizados.

OBJECTIVES: To determine factors related to nutritional riskin autonomous non-institutionalized adult elder people. METHODS: Cross-sectional study including 660 autonomous non-institutionalized adult elder people. Participants were assessed in 12 social centres (province of Valencia) and selected using stratified sampling by blocks. INCLUSION CRITERIA: age 65 or over, living at home, functionally autonomous, having lived for more than 1 year in the province of Valencia, regularly visiting social centres and voluntary participation in the study. MNA is used for nutritional assessment and factors associated to nutritional status are collected by means of an ad-hoc survey. RESULTS: Out of the 660 study subjects, 48.33% are male and 51.67% are female, mean age is 74.3±6,57. 23.33% show malnutrition risk. Independent factors associated to malnutrition risk -with adjusted prevalence odds ratioare: absence of academic education (OR=2.29), feeling lonely (OR=2.34), following controlled diets (OR=0.55), reduced appetite (OR=2.56), number of fractions in daily intake (OR=0.66), suffering from xerostomia (OR=1.72), swallowing difficulties (OR=2.30), number of chronic diseases (OR=1.38) and having suffered from acute diseases during the last year (OR=2.03). An increase in BMI is associated with a good nutritional status (OR=0.85). These factors have allowed an accurate classification of 80% of the surveyed patients. CONCLUSIONS: Numerous chronic diseases, recent acute diseases, non-controlled diets, xerostomia and swallowing difficulties, eating few times a day and little appetite, feelling lonely and lacking from academic education are factors allowing the prediction of malnutrition risk in adult elder people.

Los participantes fueron evaluados en 12 centros sociales (provincia de Valencia) seleccionados mediante un muestreo estratificado por bloques. Criterios de inclusión: tener 65 años o más, vivir en el domicilio, poseer autonomía funcional, residir más de un año en la provincia de Valencia, acudir periódicamente a los centros sociales y colaborar voluntariamente en el estudio. Se usa el MNA para la valoración nutricional y se recogen factores asociados al estado nutricional en una encuesta adhoc. Resultados: De los 660 sujetos estudiados, el 48,33% son hombres y el 51,67% mujeres, la edad media es de 74,3±6,57 años. El 23,33% presentan riesgo de malnutrición. Los factores independientes asociados al riesgo de malnutrición, con el odds de prevalencia ajustada, son: no poseer estudios (OR=2,29), sentir soledad (OR=2,34), mantener dietas controladas (OR=0,55), un apetito escaso (OR=2,56), número de fracciones en la ingesta diaria (OR=0,66), sufrir xerostomía (OR=1,72), tener dificultades para deglutir (OR=2,30), el número de enfermedades crónicas (OR=1,38) y haber sufrido enfermedades agudas en el último año (OR=2,03). Un incremento en el IMC se asocia a un buen estado nutricional (OR=0,85). Estos factores nos han permitido clasificar correctamente a un 80% de los pacientes encuestados. Conclusiones: Tener numerosas enfermedades crónicas, haber sufrido enfermedades agudas recientes, mantener dietas sin control, sufrir xerostomía y dificultad para deglutir, comer pocas veces al día y con escaso apetito, sentirse solo y no tener estudios son factores que, permiten predecir el riesgo de malnutrición en los adultos mayores.

[Study on the nutritional risk of autonomous non-institutionalized adult elder people]. / Estudio del riesgo nutricional en adultos mayores autónomos no institucionalizados.

OBJECTIVES: To assess the nutritional status of autonomous, non-institutionalized, elder adults in social centers by means of the MNA scale and to analyze their distribution according to socio-demographical variables: gender, age, civil status, living with other people, educational level, and rural/urban setting. METHODS: Cross-sectional study performed in 660 autonomous, non-institutionalized elder adults in social center of the province of Valencia. The subjects were assessed at 12 social centers selected though stratified sample sets. The inclusion criteria were: being 65 years of older, living at home, having functional autonomy, residing for more than one year in the province of Valencia, attending periodically the social center, and willing to participate. The MNA scale was used for nutritional assessment. RESULTS: Of the 660 included subjects, 48.33% were males and 51.6% females; the mean age was 74.3 ± 6.57 years. 23.3% of the participants were at risk for malnutrition. The prevalence of malnutrition odds ratio was higher in: females as compared to men (OR = 1.43), subjects ≥ 85 years as compared to the 65-69 years group (OR = 2.27), widowed subjects as compared to those with a stable companion (OR = 1.82) and people with the lowest educational level as compared to those with some educational level (OR = 1.73). CONCLUSIONS: The prevalence of malnutrition risk in autonomous, non-institutionalized elder adults at social centers of the province of Valencia reaches one out of four people, being higher in widowed subjects (mostly elder women living alone) and in uneducated people.
