Older people's perceptions and experiences of older people with the Sit-to-stand activity: An ethnographic pre-feasibility study / Percepções e experiências de idosos com a atividade Sit-to-stand: Um estudo etnográfico de pré-viabilidade / Percepciones y experiencias de los adultos mayores con respecto a la actividad Sit-to-stand: Un estudio etnográfico de viabilidad previa

Abstract Objective: the purpose of this pre-feasibility study was to examine perceptions and experiences of a Sit-to-stand activity with urban Brazilian community-dwelling older people in their homes. Method: the exploration method was focused ethnography. Purposive sampling was used to recruit 20 older people. Five means of data generation were used, namely: socio-demographic surveys, participant observations, informal interviews, formal semi-structured interviews, and field notes. Data analysis was qualitative content analysis. Results: the experience of mobility-challenged older people with the Sit-to-stand activity was dependent on their mobility expectations involving many factors that worked together to influence their beliefs and attitudes towards the activity, preferences, behaviors, and cultural perceptions. The participants of this study seemed to find the activity enjoyable; however, the most noticeable shortcomings for their engagement in the Sit-to-stand activity emerged as gaps in their personal and intrapersonal needs. Conclusion: the recommendations generated from the study findings call for the design of implementation strategies for the Sit-to-stand intervention that are tailored to this particular population's needs.

Resumo Objetivo: o objetivo deste estudo de pré-viabilidade foi examinar percepções e experiências da atividade de Sit-to-stand com idosos brasileiros residentes em suas casas, no meio urbano. Método: o método exploratório foi etnografia focada. Foi utilizada a amostragem intencional para recrutar 20 idosos. Foram utilizados cinco meios de geração de dados: inquéritos sociodemográficos, observações participantes, entrevistas informais, entrevistas formais semiestruturadas e notas de campo. Os dados foram analisados mediante análise de conteúdo qualitativo. Resultados: a experiência dos idosos com problemas de mobilidade na realização da atividade Sit-to-stand dependia de suas expectativas de mobilidade envolvendo muitos fatores coordenados que, de forma conjunta, influenciaram suas crenças e atitudes em relação à atividade, suas preferências, seus comportamentos e percepções culturais. Os participantes deste estudo pareciam considerar a atividade aprazível; no entanto, as deficiências mais perceptíveis para o engajamento dos participantes na atividade Sit-to-stand surgiram de falhas em suas necessidades pessoais e intrapessoais. Conclusão: as recomendações geradas a partir dos achados do estudo convocam a concepção de estratégias de implementação da intervenção Sit-to-stand adaptadas às necessidades dessa população em particular.

Telemonitoreo y sistema de alerta en tiempo real en insuficiencia cardiaca: estudio piloto de factibilidad, aceptabilidad y eficacia / Telemonitoring and a real-time alert system in heart failure: a preliminary pilot study of feasibility, acceptability and efficacy

Resumen Introducción: Existe creciente evidencia que el telemonitoreo (TM) de pacientes con insuficiencia cardíaca (IC) parece mejorar su evolución. No se han diseñado y evaluado plataformas de TM en Argentina. El objetivo fue evaluar la factibilidad, aceptabilidad, usabilidad y eficacia preliminar de una plataforma de TM de IC. Métodos: Se realizó un ensayo piloto apareado abierto, con un modelo de intervención de un solo grupo. Los pacientes con IC fueron incluidos en una consulta ambulatoria en enero de 2021. Se diseñó una pla taforma de TM las 24 h y 7 días de la semana. El punto final primario a 30 días fue la factibilidad, aceptabilidad y usabilidad. Resultados: Se incluyeron 20 pacientes, con una media de edad 62 ± 10 años. Se analizaron 542 cargas de parámetros. La autopercepción relacionada al estado de salud en comparación al inicio fue "levemente" o "marcadamente mejor" en el 60% de los pacientes, y en 75% "de acuerdo" o "totalmente de acuerdo" que el TM mejora el cuidado de la IC. En el 80% la carga diaria de parámetros no interfirió en su vida cotidiana. La media total de adherencia farmacológica previa a la intervención de TM fue de 6.8 ± 1.3 y posterior 7.7 ± 0,4 (p = 0.019), sin encontrar diferencias en las escalas de autocuidado. Conclusión: El TM de pacientes con IC parece ser factible, con un adecuado grado de aceptabilidad. Se observó un aumento significativo en la tasa de total adherencia, plantea una hipótesis de potencial beneficio a evaluar en una muestra mayor.

Abstract Introduction: There is growing evidence that telemonitoring (TM) in heart failure (HF) seems to improve their outcome. TM platforms have not been designed and evaluated in Argentina. The objective was to evaluate the feasibility, acceptability, usability and preliminary efficacy of a HF TM platform. Methods: An open-label, paired pilot trial was conducted with a single-group intervention model. HF patients were included in an outpatient clinic in January 2021. A 24-hour*7-day TM platform was designed. The primary endpoint at 30 days was feasibility, acceptability, and usability. Results: Twenty patients were included, mean age 62 ± 10 years; 542 parameter loads were analyzed. Self-perception related to health status compared to baseline was "slightly" or "markedly better" in 60% of patients, and in 75% "agree" or "totally agree" that TM improves patient care. In 80%, the load ing of parameters did not interfere with their daily activities. The total mean pharmacological adherence prior to the TM intervention was 6.8 ± 1.3 and 7.7 ± 0.4 afterward (p = 0.019), with no differences found in the self-care scales. Conclusion: The TM of patients with HF seems to be feasible, with an adequate degree of acceptability. A significant increase in the total adherence rate was reduced, raising a hypothesis of potential benefit to be evaluated in a larger sample.

A single-centre experience of His bundle pacing without electrophysiological mapping system: implant success rate, safety, pacing characteristics and one-year follow up

INTRODUCTION@#Despite the challenges related to His bundle pacing (HBP), recent data suggest an improved success rate with experience. As a non-university, non-electrophysiology specialised centre in Singapore, we report our experiences in HBP using pacing system analyser alone.@*METHODS@#Data of 28 consecutive patients who underwent HBP from August 2018 to February 2019 was retrospectively obtained. The clinical and technical outcomes of these patients were compared between two timeframes of three months each. Patients were followed up for 12 months.@*RESULTS@#Immediate technical success was achieved in 21 (75.0%) patients (mean age 73.3 ± 10.7 years, 47.6% female). The mean left ventricular ejection fraction was 53.9% ± 12.1%. The indications for HBP were atrioventricular block (n = 13, 61.9%), sinus node dysfunction (n = 7, 33.3%) and upgrade from implantable cardioverter-defibrillator to His-cardiac resynchronisation therapy (n = 1, 4.8%). No significant difference was observed in baseline characteristics between Timeframe 1 and Timeframe 2. Improvements pertaining to mean fluoroscopy time were achieved between the two timeframes. There was one HBP-related complication of lead displacement during Timeframe 1. All patients with successful HBP achieved non-selective His bundle (NSHB) capture, whereas only eight patients had selective His bundle (SHB) capture. NSHB and SHB capture thresholds remained stable at the 12-month follow-up.@*CONCLUSION@#Permanent HBP is feasible and safe, even without the use of an electrophysiology recording system. This was successfully achieved in 75% of patients, with no adverse clinical outcomes during the follow-up period.

Qualitative systematic review of the safety and feasibility of early mobilization in critically ill patients with femoral catheters / 中国胸心血管外科临床杂志

@#Objective    To investigate the safety and feasibility of early mobilization in critically ill patients with femoral catheters, and to provide reference for guiding clinical rehabilitation training. Methods    The literature on the safety and feasibility of early mobilization in critically ill patients with femoral catheters included in PubMed, EMbase, OVID, Springer-link, Wiley Online Library, and Web of Science up to June 2021 was searched, and relevant data were extracted for analysis. Results    Seventy-two papers were initially screened, and 12 papers that met the criteria were finally included, covering 1 056 patients, and 489 patients had femoral catheters. Patients underwent 6 495 sessions of physical therapy, and a total of 62 patients had adverse events, including 14 (2.86%, 14/489) patients with catheter-related adverse events. Conclusion    Although early mobilization in critically ill patients with femoral catheters may lead to adverse catheter-related events, the incidence is low. Therefore, the associated risks and benefits should be weighed in clinical practice, and femoral catheter is not recommended as a contraindication for early mobilization in critically ill patients.

The feasibility of oral targeted drug delivery: Gut immune to particulates?

Targeted drug delivery is constantly updated with a better understanding of the physiological and pathological features of various diseases. Depending on high safety, good compliance and many other undeniable advantages, attempts have been undertaken to complete an intravenous-to-oral conversion of targeted drug delivery. However, oral delivery of particulates to systemic circulation is highly challenging due to the biochemical aggressivity and immune exclusion in the gut that restrain absorption and access to the bloodstream. Little is known about the feasibility of targeted drug delivery via oral administration (oral targeting) to a remote site beyond the gastrointestinal tract. To this end, this review proactively contributes to a special dissection on the feasibility of oral targeting. We discussed the theoretical basis of oral targeting, the biological barriers of absorption, the in vivo fate and transport mechanisms of drug vehicles, and the effect of structural evolution of vehicles on oral targeting as well. At last, a feasibility analysis on oral targeting was performed based on the integration of currently available information. The innate defense of intestinal epithelium does not allow influx of more particulates into the peripheral blood through enterocytes. Therefore, limited evidence and lacking exact quantification of systemically exposed particles fail to support much success with oral targeting. Nevertheless, the lymphatic pathway may serve as a potentially alternative portal of peroral particles into the remote target sites via M-cell uptake.

Application of three-dimensional imaging device to colonoscopy / 中华消化内镜杂志

Objective:To evaluate the application of three-dimensional (3D) imaging device to colonoscopy.Methods:A total of 60 patients who underwent painless colonoscopy in Beijing Friendship Hospital, Capital Medical University from November to December, 2019 were enrolled and divided into 2 groups according to random code. Each patient underwent colonoscopy twice, while 2D colonoscopy was used for cecal intubation. Thirty patients were assigned to the experimental group (primary withdrawal used 3D colonoscopy, and secondary withdrawal used 2D colonoscopy), and 30 others to the control group (primary withdrawal used 2D colonoscopy, and secondary withdrawal used 3D colonoscopy). The detection of polyps, the withdrawal time, operating experience, image quality and complication were evaluated in the two groups.Results:The polyp detection rate at the first colonoscopy in the experimental group was 77.3% (17/22), which was higher than 43.5% (10/23) in the control group ( χ2=5.351, P=0.021). Ten operators in the experimental group had dizziness, while the operators in the control group had no dizziness ( P=0.001). There were no significant differences between the two groups in the polyp diameter [0.50 (0.70) cm VS 0.30 (0.20) cm, U=57.000, P=0.170], withdrawal time (4.6±1.5 min VS 5.2±1.9 min, t=-1.189, P=0.239) or image quality (27 cases with 3 points in the identification of lesion nature, and 28 cases with 3 points in the identification of duct both in the two groups, P=1.000) at the first colonoscopy. No complication occurred in either group. Conclusion:Application of 3D imaging device is feasible for colonoscopic polyp detection, and it can be used in clinical practice.

Telehealth for Parkinson disease patients during the COVID-19 pandemic: the TeleParkinson study / Telesaúde para pacientes com doença de Parkinson durante a pandemia de COVID-19: o estudo TeleParkinson

Abstract Background Telemedicine allows Parkinson disease (PD) patients to overcome physical barriers to access health care services and increases accessibility for people with mobility impairments. Objective To investigate the feasibility indicators of a telehealth intervention for PD patients, including patient recruitment, attendance, technical issues, satisfaction, and benefits on levels of physical activity and sleep. Methods We conducted a single-center, single-arm study of telehealth video consultations using WhatsApp (Meta Platforms, Inc., Menlo Park, CA, USA). Also, we collected the feasibility indicators as the primary endpoints. All the patients in the study were previously evaluated in person by the same team. Results Patient recruitment, attendance, and technical issues rates were 61.3%, 90.5%, and 13.3%, respectively, with good scores of patient acceptance and satisfaction with the study intervention. The telehealth intervention improved physical activity, including the number of walks for at least 10 continuous minutes (p = 0.009) and the number of moderate-intensity activities lasting at least 10 continuous minutes (p = 0.001). The Pittsburgh sleep quality index (PSQI) scores also improved for one of its components: perceived sleep duration (p < 0.001) and for total Pittsburgh score (p < 0,001). The average travel time saving was 289.6 minutes, and money-saving was R$106.67 (around USD 18; almost 10% of the current minimum wage in Brazil). Conclusions Direct-to-patient telehealth video consultations proved to be feasible and effective and had a positive impact on physical activity levels and sleep in PD patients.

O Índice de Qualidade do Sono de Pittsburgh melhorou nos seguintes componentes: duração percebida do sono (p < 0,001) e escore total (p < 0,001). A média do tempo de viagem médio poupado foi de 289,6 minutos, e a economia financeira foi de R$ 106,67 reais (por volta de USD 18; quase 10% do salário mínimo atual do Brasil). Conclusões As consultas por vídeo provaram ser viáveis e efetivas, com impacto positivo nos níveis de atividade física e sono de pacientes com DP.

Implementation Research: The Need of the Hour

Formative research creates evidence. Evidence-based interventions are implemented in community settings. In the past, evidence-based interventions have failed to get desired outcomes. The tuberculosis control program despite being evidence based did not succeed at the beginning. Similarly, evidence-based treatment of hypertension and diabetes has not yet controlled these diseases. This is where the role of implementation research (IR) starts. IR either as part of evidence-based research or independently should be a part of health programs so that the program shall be able to ensure feasibility, fidelity, penetration, acceptability, sustainability, efficiency, effectiveness, and equity

Progress of mesenchymal stem cell-derived exosomes for management of preeclampsia / 中华围产医学杂志

Pre-eclampsia is a common complication of pregnancy that can result in serious consequences for mother and child health, but there are currently no established therapeutic options. Mesenchymal stem cell-derived exosomes (MSC-exos) are nanoparticles carrying bioactive substances such as proteins, lipids, and nucleic acids, and serve as a medium of intercellular communication. MSC-exos are involved in many important physiological processes, including immunological regulation, cell proliferation and migration, and angiogenesis, thereby play an important role in tissue repair and potentially clinical treatment strategies. In recent years, the treatment strategies of MSC-exos have become an emerging hot topic in the management of ischemic diseases, immune dysfunction, inflammatory diseases, and other fields. We review the advantages and challenges of MSC-exos as a new acellular therapy strategy as well as the feasibility of MSC-exos in managing preeclampsia, from its biological role in the important pathogenesis of preeclampsia, such as trophoblastic and endothelial cell dysfunction, immune imbalance at the maternal-fetal interface, and oxidative stress, and summarize the progress of animal experimental research in this field.

Twelve-section ultrasonic screening diagnosis method for neonatal complex congenital heart disease in primary hospitals at county level / 中华围产医学杂志

Objective:To investigate the feasibility of "twelve-section ultrasonic screening diagnosis method" in screening for neonatal complex congenital heart disease (CHD) in primary hospitals.Methods:This is a prospective study. A total of 71 580 newborns were screened for CHD using the "twelve-section ultrasonic screening diagnosis method" from four pilot units in Hebei province, which were Bo'ai Hospital of Huanghua Development Zone, Traditional Chinese Medicine Hospital of Fengning County, Maternity & Child Healthcare Hospital of Tang Country, and Maternity & Child Healthcare Hospital of Rongcheng Country, from November 2015 to December 2019. Another 262 children with CHD were enrolled, including 39 with complex CHD. These cases received ultrasonography at four pilot units above and then were transferred to CHD Screening Diagnosis and Treatment Center of Hebei Children's Hospital (our center) prior to the implementation of "twelve-section ultrasonic screening diagnosis method" from June 2012 to June 2014, who were all confirmed by surgery. Set the diagnosis results of our center as the gold standard, the sensitivity, specificity, and diagnostic consistency rate in screening for complex CHD cases were calculated. Receiver operating characteristic (ROC) analysis and Chi-square test were used to compare and analyze the sensitivity for screening neonatal complex CHD before and after implementing the method. The screening results of complex CHD after implementing the method between the pilot units and our center as well as between the four pilot units were compared and analyzed using Chi-square test. Results:A total of 553 (0.77%) CHD cases were detected by the "twelve-section ultrasound screening diagnosis method", including 66 cases of complex CHD and 487 cases simple CHD. Among the cases screened using the method, there were three false negative cases (one case with total anomalous pulmonary venous drainage, one with abnormal coronary artery originating from pulmonary artery, and one with atresia of distal to the left subclavian artery, aortic arch and left aortic arch of double-arch), one false positive case (false echo loss of aortopulmonary septal that was misdiagnosed as aortopulmonary septal defect), five cases of misdiagnosis (one common pulmonary venous atresia case that was misdiagnosed as total anomalous pulmonary venous drainage, one persistent stenosis of the fifth aortic arch that was misdiagnosed as coarctation of aorta, one pulmonary artery sling that was misdiagnosed as absence of left pulmonary artery, one severe coarctation of aorta that was misdiagnosed as interruption of aortic arch, and one aortic isthmus atresia that was misdiagnosed as coarctation of aorta), and all were complex CHD cases. A total of 68 cases (12.3%) of complex CHD were confirmed by our center. The overall sensitivity, specificity, and diagnostic consistency rate of screening were 95.6% (65/68), 99.8% (484/485), and 86.8% (59/68), respectively and the area under ROC curve was 0.98. Before the implementation, the overall sensitivity, specificity, and diagnostic coincidence rates of ultrasonic screening for complex CHD were 69.2%(27/39), 95.5%(213/223), and 61.5% (24/39), respectively, and the area under ROC curve was 0.82. The sensitivity of complex CHD screening was significantly increased after implementing the method ( χ2=14.28, P<0.05). There was no significant statistical significance in the sensitivity for screening complex CHD after the implementation between the pilots and our center or between the four pilots (all P>0.05). Conclusions:"Twelve-section ultrasonic screening diagnosis method" is suitable for the screening of neonatal complex CHD in hospitals at the county level. However patients with some special types of complex CHD are recommended to be transferred for a more accurate diagnosis.

Physical activity supported by mobile technology program (PAT-Back) for older adults with back pain at primary care: a feasibility study protocol

Abstract Aim: Low back pain (LBP) is disabling in older adults. Although physical activity interventions positively affect LBP, older adults are underrepresented in the literature. We aim to investigate the feasibility of conducting a study to evaluate a primary care program of exercise therapy and pain education, supported by mobile technology, for older adults with chronic LBP (compared to best practice advice). Methods: In this parallel, two-arm randomized pilot trial, we will recruit adults aged 60 years and older with chronic LBP. The experimental group (Physical Activity supported by low-cost mobile technology for Back pain-PAT-Back) will consist of an 8-week group exercise program based on pain education, exercises, graded activities, and in-home physical activity. Text messages will be sent to promote adherence to home exercises. The control group will receive an evidence-based educational booklet given during one individual consultation. Outcomes will include recruitment rate, adherence and retention rates, level of understanding of the intervention content, perception of the utility of mobile technology, compliance with the accelerometer in a sub-sample of patients, and adverse events. Discussion: The results of this study will form the basis for a large randomized controlled trial. This innovative approach to managing LBP in the primary care setting for older adults, if proven to be effective, can bring an important advance in the knowledge of chronic LBP management to this population.

Masaje de Field para la ganancia de peso en prematuros extremos. Estudio de viabilidad y aceptabilidad / Field massage for weight gain in extremely premature babies. Feasibility and acceptability study

Introducción: Una de las principales problemáticas del prematuro extremo es la limitación en su ganancia de peso debido a factores propios de su inmadurez (2,4); el desconocimiento acerca del tipo, el tiempo y la cantidad de estimulación que debe recibir, rescata la necesidad de indagar en nuevas intervenciones desde el cuidado de enfermería (4,11). Objetivo: Determinar la viabilidad y aceptabilidad de la terapia de masaje de Field, en prematuros extremos en una Unidad Neonatal de una institución de IV nivel, y los efectos en relación con la ganancia de peso. Metodología: Estudio cuantitativo, cuasi experimental, realizado en 15 prematuros extremos, que comparó el peso pre y post intervención, y un análisis para la estimación del efecto; se determinó la viabilidad del estudio mediante tasas de selección, reclutamiento y seguimiento y la aceptabilidad de la intervención en términos de satisfacción de los padres. El proceso de selección y reclutamiento se efectuó por más de 4 meses; la terapia se realizó 3 veces al día, durante 15 minutos, por 5 días consecutivos; posteriormente, se aplicó un cuestionario de aceptabilidad a las madres de los neonatos masajeados. Resultados: Se presentó una ganancia de peso significativa, lo cual podría ser atribuido al masaje, sin embargo, debe ser evaluado en futuras investigaciones frente a un grupo control. El estudio se hace menos viable en cuanto a la tasa de selección, si la muestra es captada durante poco tiempo, reduciendo la posibilidad de aplicar la intervención en una muestra significativa; en cuanto a reclutamiento y seguimiento, es totalmente viable. Es una terapia muy aceptada por las madres en términos de idoneidad, conveniencia y efectividad; sin embargo, se debe fortalecer desde sus riesgos y adherencia.

Introduction: One of the main problems of the extreme premature infants is the limitation in their weight gain due to factors inherent to their immaturity (2,4), the lack of knowledge about the type, the time, and the amount of stimulation they should receive, it also highlights the need to investigate new interventions in nursing care (4,11). Objective: To determine the feasibility and acceptability of Field's massage therapy in extreme premature infants in a Neonatal Unit of a level IV institution, and the effects in relation to weight gain. Methodology: Quantitative, quasi-experimental study, carried out in 15 extreme preterm infants, where pre and post intervention weight was compared, a analysis for effect estimation; the feasibility of the study was determined by selection, recruitment and followup rates and the acceptability of the intervention in terms of parental satisfaction. The selection and recruitment process were carried out for more than 4 months; the therapy was performed 3 times a day, for 15 minutes per session, for 5 consecutive days; subsequently, an acceptability survey was applied to the mothers of the massaged neonates who completed the intervention days. Results: here was a significant weight gain, which could be attributed to the massage, however, it should be evaluated in future research against a control group. The study becomes less viable in terms of the selection rate, if the sample is captured for a short time, reducing the possibility of applying the intervention in a significant sample; in terms of recruitment and follow-up, it is totally feasible. It is a therapy that is highly accepted by mothers in terms of suitability, convenience and effectiveness; however, it must be strengthened from its risks and adherence.

Study on the current status and feasibility of payment reform for TCM dominant diseases from the perspective of clinicians / 中国药房

OBJECTIVE To understan d the c urrent situation and feasibility of payment reform for TCM dominant diseases from the perspective of clinicians ，so as to provide reference for optimizing and improving the reform scheme. METHODS A questionnaire was designed by ourselves ，and a simple random sampling method was used to select clinicians from the pilot hospitals of payment reform for TCM dominant diseases in Guizhou province to conduct a face-to-face questionnaire survey. SPSS 20.0 software was used for statistical analysis. The single-factor analysis and ordered Logistic regression analysis of multi-factor were used to analyze the influential factors of reform feasibility. RESULTS A total of 420 questionnaires were distributed in this survey，and 413 valid questionnaires were recovered ，with an effective rate of 98.3％. Totally 86.0％ of the clinicians thought that it was feasible for the reform to be carried out in their hospitals ，and 81.8％ thought that the selected TCM dominant diseases in the pilot hospitals were reasonable. After the reform was carried out ，61.0％ and 58.8％ of clinicians indicated that the daily number of patients treated in their departments and their willingness to communicate with patients increased ，respectively；60.3％ indicated that the difficulties and obstacles encountered in the reform were the complexity and diversity of TCM diseases ，for the treatment of patients with integrated traditional Chinese and Western medicine ，which was difficult to use a unified disease and surgery code to correctly code ；76.3％ indicated that the greatest advantage of the reform implementation was the improvement of medical quality ，while 54.2％ indicated that the greatest disadvantage was the excessive restriction of doctors ’autonomy. The results of multi-factor ordered Logistic regression analysis showed that changes in treatment services （changes in readmission rate of patient），the reasonableness of the selection of TCM dominant diseases ，and whether to reduce medical costs ，improve doctor-patient relationship ， and promote hierarchical treatment were the influential factors of reform feasibility after the implementation of reform （P＜0.05）. CONCLUSIONS It is feasible to carry out payment reform for TCM dominant diseases in Guizhou province ，but it is still in the exploratery stage ，and there are many factors affecting the feasibility of the reform. It is suggested that in the future ，when promoting in the whole pr ovince and even the whole c ountry，we should pay attention to selecting more and more reasonable dominant diseases for payment reform ， further standardize the diagnosis and treatment behavior of clinicians ， control the unreasonablegrowth of medical expenses ， strengthen communication between clinicians and patients， improve the accurate diagnosis rate of traditional Chinese medicine diseases ，implement hierarchical calculation of dominant diseases ，and promote hierarchical diagnosis and treatment of medical institutions.

RESUMO Os estudos de viabilidade técnico econômica são elementos primordiais para a viabilização de projetos de saneamento, inclusive de incineração de resíduo sólido urbano com recuperação energética. O artigo teve como base os padrões para estudos de viabilidade técnico econômica conforme Portaria n° 557 do Ministério das Cidades, previstos na lei n° 11.445 que estabelece diretrizes nacionais para o saneamento básico. Foram realizadas visitas técnicas em quatro incineradores em operação na Suíça e dois em Portugal, com o objetivo de estabelecer um benchmarking para referenciar a análise da aplicação da Portaria, a identificação dos fatores críticos que dificultam a adoção dessa tecnologia no Brasil, assim como as ações necessárias para a viabilidade técnico-econômica do incinerador. Os principais fatores críticos identificados foram a localização da planta, o efeito Not in My Backyard, a concepção de conflito entre reciclagem e incineração, o elevado investimento inicial, o risco de adoção de tecnologias já superadas, a falta de experiência e mão de obra capacitada local, a variação e sazonalidade na alimentação de resíduo sólido urbano, a volatilidade do preço da energia no mercado, as receitas mínimas para viabilidade financeira, a adequação do arcabouço legal e a seleção de modelo de negócio adequado.

ABSTRACT Technical-economic feasibility studies are essential elements for making sanitation projects feasible, including projects of MSW incinerators with energy recovery. This article is based on the reference standards for technical-economic feasibility studies according to Ordinance No. 557 (2016) of the Ministry of Cities, provided for in Law No. 11.445, which establishes national guidelines for basic sanitation. Technical visits were carried out in four incinerators in Switzerland and two in Portugal in order to establish a benchmark to reference the analysis of the application of the Ordinance, the identification of critical factors that hinder the adoption of this technology in Brazil, as well as the necessary actions for technical-economic feasibility. The objective of this article is to propose an adaptation of the technical-economic feasibility studies model of the Ordinance for a MSW incinerator project with energy recovery, identifying the critical factors and actions related to the financial-economic viability that hinder the adoption of this technology in Brazil. The critical factors identified were the location of the plant, the Not in My Backyard effect, the concept of conflict between recycling and incineration, the high initial investment, the risk of adopting technologies that have already been overcome, the lack of experience and hands of qualified local work, variation and seasonality in MSW supply, volatility in the price of energy in the market, minimum revenues for financial viability, adequacy of the legal framework, and selection of an appropriate business model.
