Оценка рисков безопасности промысловых схем

The design of existing fishing schemes is carried out according to prototypes, which causes a low level of safety in fishing operations, and, as a result, leads to an increase in accidents among crew members. As practice shows, such cases can be avoided already at the stage of designing a field scheme. In order to find out how changes in fishing schemes in the direction of increasing safety will affect their efficiency of use, the paper proposes to assess the safety risks of a fishing scheme, where the criterion of safety risks acts as the main criterion. To conduct such an assessment, a review was made of large-capacity stern trawlers in the amount of 5 units, with the power of trawler power plants from 882.6 kW to 5295 kW. After evaluating the safety risks of these vessels, the dependences of the safety risk factor on the power of the power plant and the power of the fishing equipment spent on operations were obtained. This analysis was carried out on the basis of a previous study on the efficiency of fishing schemes, where the main criterion was the coefficient of mechanization of fishing operations.

Efficacy and safety of low levels of low-density lipoprotein cholesterol: trans-ancestry linear and non-linear Mendelian randomization analyses.

LDL cholesterol (LDL-C) is a well-established risk factor for coronary artery disease (CAD). However, the optimal LDL-C level with regard to efficacy and safety remains unclear. We aimed to investigate the causal relationships between LDL-C and efficacy and safety outcomes. We analyzed 353,232 British from the UK Biobank and 41,271 Chinese from the China-PAR project. Linear and non-linear Mendelian randomization (MR) analyses were performed to evaluate the causal relation between genetically proxied LDL-C and CAD, all-cause mortality, and safety outcomes (including hemorrhagic stroke, diabetes mellitus, overall cancer, non-cardiovascular death, and dementia). No significant non-linear associations were observed for CAD, all-cause mortality, and safety outcomes (Cochran Q P > 0.25 in British and Chinese) with LDL-C levels above the minimum values of 50 mg/dL and 20 mg/dL in British and Chinese, respectively. Linear MR analyses demonstrated a positive association of LDL-C with CAD (British: odds ratio [OR] per unit mmol/L increase, 1.75, P = 7.57 × 10-52; Chinese: OR, 2.06, P = 9.10 × 10-3). Furthermore, stratified analyses restricted to individuals with LDL-C levels less than the guidelines-recommended 70 mg/dL demonstrated lower LDL-C levels were associated with a higher risk of adverse events, including hemorrhagic stroke (British: OR, 0.72, P = 0.03) and dementia (British: OR, 0.75, P = 0.03). In British and Chinese populations, we confirmed a linear dose-response relationship of LDL-C with CAD and found potential safety concerns at low LDL-C levels, providing recommendations for monitoring adverse events in people with low LDL-C in the prevention of cardiovascular disease.

Assessment of the impact of waste of mining and chemical enterprises on surface water quality

The mining and chemical industry causes pollution of the soil and water environment both during its operation and after its termination. The waste of large industrial complexes poses a particular danger to the aquatic environment. Tailings storage facilities located in the Dniester River basin are characterized by a low level of environmental safety of these facilities, which indicates unsatisfactory management and their neglected state. Violation of the rules for the operation of tailings can lead to industrial accidents on a transboundary scale with uncontrolled emissions of pollutants and devastating consequences for the environment.The purpose of the study is to assess the impact of waste from State Enterprise “Rozdil mining and chemical enterprise “Sirka”” on the quality of the largest water bodies in the area of influence of this enterprise – lakes Serednie, Hlyboke and Kysle, located near industrial waste storage areas, and the mine channel through which water flows into the transboundary river Dniester.The work experimentally determined and analyzed the indicators of water samples taken in 2021–2022 from the largest reservoirs in the zone of influence of SE “Rozdil MCE “Sirka”” – lakes Serednie, Hlyboke and Kysle, located near industrial waste storage sites and the water from which flows into the transboundary Dniester River along the mining channel (channel of Lake Hlyboke-Dniester River).In the analyzed water samples of the Hlyboke, Seredne, Kysle lakes and the mine channel, an excess of the MPC for sulfates is observed by 1.5–6 times, and the mineralization index by 2.3–3 times. There is a tendency to decrease the content of ammonium nitrogen in the studied reservoirs. In 2017 and in 2021–2022, there was a deviation from the water pH standards in Lake Kysle, as well as exceeding the MPC for phosphates, sulfates, ammonium nitrogen, and mineralization. In the mine channel, the maximum limit was found to be exceeded according to the following indicators: pH, sulfates, ammonium nitrogen.It is expedient to consider the issue of environmental safety of tailings at both the international and national levels. It is extremely important to improve the policy of prevention and liquidation of the consequences of accidents, interaction between civil protection management bodies and enterprises.

ASSESSMENT OF HIGH-PROTEIN QUALITY FEED ADDITIVES FROM BY-PRODUCTS MANUFACTURE OF SUNFLOWER OIL

The article states that until 2022, Ukraine will occupy the first place in the world food market in the production of sunflower, sunflower oil and export of sunflower oil. The production of sunflower has always been sufficiently profitable, and the products of its processing competitive on the domestic and world markets. They are also an important component of food and feed protein resources. The production of complete ration compound feed for farm animals and poultry is restrained by a shortage of protein components, a low level of sanitary and hygienic safety of protein raw materials of animal origin. This leads to a decrease in the efficiency of feed, their costs and, as it should be, a shortage of livestock products. Cake and meal are high-protein raw materials, which are obtained in the amount of 1/3 of the mass of processed seeds during the production of sunflower oil. The fodder value of sunflower cake and meal is given. Factors that negatively affect the nutritional value and availability of nutrients of sunflower meal in the feed of farm animals and poultry were analyzed. The choice of components for the production of high-protein feed additive is theoretically justified. The indicators of the quality of sunflower seeds and by-products of their processing, which meet the requirements of DSTU, have been determined. On the basis of theoretical and experimental data, a structural scheme for the production of a high-protein feed supplement based on sunflower cake and meal is proposed, which involves the preliminary preparation of the by-products of sunflower oil production - cake and meal, with the following dosage in the amount: 75% sunflower meal, 10% sunflower cake and 15% limestone flour. The physical properties and microbiological indicators of the quality of a highprotein feed additive were experimentally determined, and it was determined that, compared to a loose, granular high-protein feed additive, it has the following advantages: increased nutritional value, has a greater volumetric weight, sanitary quality, which leads to saving space during transportation and better storage.

Analysis of Occupational Injuries in Construction and Offer of a Technical Solution Increasing Tower Crane Stability

The article contains analysis of the number of occupied human resources and the level of occupational injuries by kinds of economic activity based on ROSSTAT data. The analysis resulted in a low level of occupational safety in the construction sphere. To ensure safe tower crane operation with account for impact of random factors and loads a technical solution was offered that provides for additional tower crane stability by moving the counterbalance over traveling rollers in the direction opposite to probable collapse, thus preventing crane tipping over. As a result, it becomes possible to change the value of holding moment at high loads on the tower crane boom. This technical solution will ensure reliability in the process of operation of lifting machines and it meets all occupational health and safety requirements on construction sites.

Социальные сети как правовой феномен

The emerging institution of legal regulation of social networking in different states appears in different ways. The comparative legal method of the studying made it possible to select two models: western (USA, Germany, France) and eastern (China). The Western model of legal regulation comes from “freedom of networked battlefield” and “freedom of speech”, the eastern one comes - from the “information security priority” and “deanonymiration of social networking”. Relations in the social networking have acquired independent features: big freedom of expression, a culture of clip thinking, “rudeness” in the relationships as the norm, as an impossible to nobility to identify the subject and the lack of responsibility. Under the studying of social networking, researchers form the conceptual provisions of “digital life” and “digital death” of personality. In Russia, the main problems of regulation social networking are the lack of legal definitions of the concepts “social networking”, “account”; industry uncertainty of public relations, which from in the social networking; a low level of safety for minors and the elderly people. It is proposed to consider social networking as public relations as an intersectoral legal institution of civil, labor, administrative and criminal law, also as procedural industries; legalize concept “social networking” and “account”; establish information security filters for minors and elderly people.

Aerodynamic Design of Cooling Guide for Electrical Machine in Electric Ducted Fan

Abstract Electric ducted fan has newly emerged as the most compact type of propulsion fan for flying cars, because of its flexible configuration arrangement, low noise level and high safety level operation. Typically, an electric ducted fan is composed of a hub-driven fan and a hub-mounted inner rotor electrical machine. The thermal management of the hub-mounted electrical machine is essential because it determines the machine's continuous output power and reliability, as well as the fan thrust force. The heat transmitted from the stator winding to the cooling guide vane (CGV) is dissipated by introducing the air flow at hub region to the CGV. Therefore, in order to better improve the thermal performance of the CGV, an aerodynamic design of CGV is proposed in this paper for better thermal management of stator end-windings. First, for a certain desired power output of electrical machine under temperature constraints of stator winding, lumped thermal network is established to derive the requirement of heat transfer coefficients of the CGV. Then, from engineering feasibility, three different CGVs including straight type, arc-shape type and airfoil-shape type are tested by computational fluid dynamics. The evaluation of the CGV designs include the flow characteristics, power requirements, and thermal characteristics for stator winding cooling purposes. In comparison with the conventionally straight type CGV, improvements are gained from the designed arc-shape type and airfoil-shape type cooling configurations, whereas the fan thrust force remains the same simultaneously. It is verified that the arc-shape type and airfoil-shape type CGVs are promising in enhancing the thermal management performance of the electrical machine stator winding without power requirement.

Perception and Decision of Public Transport Users in Palu City

Public transport users in Palu City are decreasing every year. The low quality of public transport services is the main reason people are reluctant to use them. Based on this condition, the research was conducted to understand the user’s perceptions and decisions of public transportation services, exceptionally public transport, in Palu City. The method used in this research is the distribution of questionnaires to respondents from 8 sub-districts in Palu City. Data processing on 361 respondents was carried out by descriptive analysis. The results of the study illustrate that the people of Palu City, in general, do not use public transportation (91.9%) for various reasons, including long waiting times (67.2%), unclear routes (43.8%), inadequate stopping places (32.8%), non-uniform fares (8.8), poor vehicle conditions (33.7), poor driver behaviour (7.65), and low level of safety (18.5). The level of satisfaction for users of public transportation is satisfied (31.3%) and for users of private vehicles is not satisfied (41.5%) and uncomfortable (33.7%). The data also shows that 77.3% of respondents use motorcycles in their daily travel activities. This study shows that implementing online applications and free tariffs will increase public transport users by 61.7% dan 70.3%, respectively.

How to design an ecological restoration project in fragile inland basins: A case study in arid regions of China

Ecological protection is the basis for sustainable development of inland river basins in arid areas with fragile ecological environments. The aim of our study is to diagnose the ecological problems and build the ecological security pattern (ESP) of the Aksu River basin (ARB) in Xinjiang which is located in northwest of China. The spatial measurement of ecosystem service value (ESV) was employed to identified ecological problems. Using cold/hot spot detection analysis and the minimum cumulative resistance (MCR) model, the ESP at three security levels were constructed. The results showed that the ESV of ARB showed an upwards trend from 1990 to 2018, the function of water conservation, waste treatment and soil formation and retention grew fastest. The ESV of ARB in 2018 ranged from 5390 yuan/hm 2 to 131,080 yuan/hm 2 . The high-value areas were mainly located in the oasis and the northern mountainous, the low-value areas were widely distributed in desert. The ecological source areas of high, medium and low safety levels were 1806.30 km 2 , 3416.80 km 2 and 4804.32 km 2 , respectively. Three kinds of ecological protection engineering models were proposed for the four types of ecological protection zones based on the ecological problem identification in ARB. To provide a decision-making basis for ecological environmental management and regional sustainable development in the ARB, the optimization patterns of points (ecological protection projects), lines (ecological corridors) and polygons (ecological source areas) were constructed. The results of this study can also serve as a reference for ecological environmental protection in other arid inland river basins.

Walking down the street: how does the built environment promote physical activity? A case study of Indonesian cities

ABSTRACT This research merges individual self-reported physical-activity data from the fifth wave of the Indonesia Family Life Survey (IFLS) with data on Indonesian cities’ and municipalities’ built environments and employs cross-sectional multilevel regression to disentangle the relevant factors that affect individual incentives to engage in physical activity. The results suggest that high-density settings and land-use diversity in Indonesian urban settings adversely affect the incentive to engage in physical activity. Our finding reflects the common case of developing countries where the main problem arises from insufficient urban planning, which further results in other issues such as conventional land use and low-level safety and security. Thus, the result implies the urgency to improve built-environment planning in Indonesia to create a more supportive living environment that encourages residents to be more physically active, hence creating a healthier society.

Identifying the determinants and understanding their effect on the perception of safety, security, and comfort by pedestrians and cyclists: A systematic review

The continuous growth of the world population and its agglomeration in urban cities, demand an increasing need for mobility, which in turn contributes to the worsening of traffic congestion and pollution in cities. Therefore, it is necessary to promote active travel, such as walking and cycling. However, this is not an easy task, as pedestrians and cyclists are the most vulnerable link in the system, and low levels of safety, security and comfort can contribute to choosing private cars over active travel. Hence, it is essential to understand the determinants that affect the perceptions of pedestrians and cyclists, in order to support the definition of policies that promote the use of active modes of transport. Thus, this article fills an important gap in the literature by identifying and discussing the objective and subjective determinants that affect the perceptions of safety, security and comfort of pedestrians and cyclists, through a systematic review of the literature published in the last ten years. It followed the PRISMA statement guidelines and checklist, resulting in 68 relevant articles that were carefully analyzed. The results show that the perception of safety is negatively affected by fear of traffic-related injuries, fear of falling related to infrastructure and infrastructure maintenance, and negative behavior of drivers. Regarding security, crime was the major concern of pedestrians and cyclists, either with emphasis on the person or on personal property. With regard to comfort, high levels of air and noise pollution, lack of vegetation, bad weather conditions, slopes and long commuting distances negatively affected the users' perception. The results also suggest that poor lighting affects all domains, providing a negative perception of safety, security and comfort. Similarly, the presence of people is seen as negatively influencing the perception of safety and comfort, while the absence of people negatively impacts the perception of security. Therefore, the findings achieved by this study are key to assist in the definition of transport policies and infrastructure creation in large smart cities. Additionally, new transport policies are proposed and discussed.

A virtual reality craving study in tobacco addiction: The role of non-pharmacological support in tobacco detox therapy.

Nicotine addiction is a widespread, worldwide epidemic, causing six million deaths per year. A large variety of treatments for smoking cessation are currently available, including Cytisine, which is a promising drug due to its low cost and high safety levels. Notwithstanding the important amount of research on tobacco addiction treatments, smoking remains one of the most difficult substance use disorders to treat, probably also due to the fact that pharmacological treatment often overlooks other maintaining factors in this addiction, such as sensory impact and cue reactivity. To address this gap in both treatment protocols and scientific literature, we propose a study protocol in which we will compare the effects of combining Cytisine with Nirdosh, a herbal tobacco substitute, to Cytisine only in two groups of patients (C + N and C) who will also undergo exposure to four different virtual reality settings that will assess the importance of environmental cues. We will further assess mood and craving in the two samples, and include a control group taken from the general population. We expect the C + N group to report a more positive mood and a lower sensitivity to tobacco-related environmental cues.

The Impact of the Age of the Driver of Freight Transport on the probability of being involved in a Traffic Accident (Case Study in Krian – Taman Sidoarjo Road)

Traffic accident is one of the traffic problems that caused deaths, injuries and material loses. The high number of traffic accident is an indicator of the low level of road traffic safety. Krian – Taman Sidoarjo road has become one of black site area. According to data from the Sidoarjo Resort Police, there have been 66 traffic accidents during 2015 to 2020. The majority of accidents involve freight transport compared to passenger transport. Therefore, it is necessary to conduct research to find out the factors of freight transport drivers that affect the possibility of traffic accidents in Krian – Taman Sidoarjo road. Methods of data collection using questionnaires to drivers of freight transportation. While the analystical method used is descriptive analysis and logistic regression using data from questionnaires. The result of research shows that the older the driver, the higher the probability of being involved in a traffic accident

ІНСТИТУТ КРИМІНАЛЬНОГО ПРОСТУПКУ У ЗАКОНОДАВСТВІ ЗАРУБІЖНИХ КРАЇН

The analysis of scientific works on the definition of crime and misdemeanor in the legislation of foreign countries (France, Germany, Switzerland, Austria, Italy, Portugal, Denmark, Poland, Republic of Moldova, Baltic countries, England, USA, Canada) was carried out. It was found that different criteria are used to distinguish between a crime and a misdemeanor in the criminal law of foreign countries: the main ones are: the material criterion (seriousness of the act) in France; a formal criterion (the amount of punishment) in Austria and Germany, in Germany this division is based on the minimum amount of punishment that can be imposed for their commission; formal sign (type of punishment) in Switzerland; form of guilt in Poland. It was concluded that scientists single out a criminal misdemeanor as a special type of criminal offense, which has a relatively low level of public safety, leads to a greater application of the principles of humanism and a regime of responsibility other than crimes. The issue of normative legal acts regulating criminal misdemeanors is considered. It is noted that the law of Switzerland, Italy, Greece, Spain and Portugal has a direct requirement to define misdemeanors in the laws. In other states, the composition of misdemeanors and penalties for them are established both in laws and by-laws. In the author's opinion, it is more expedient to regulate the various aspects of a criminal misdemeanor both by laws and by-laws; the latter detail and concretize the legislative prescriptions, without going beyond them at the same time. The debate on the expediency of adopting an independent (separate) normative act on criminal misdemeanor was considered. Attention is drawn to the argumentation of the advantages of the simplified proceedings of the institution of a criminal misdemeanor and its features, the grounds for its isolation in the criminal legislation. The proposals of specialists regarding the adoption of this practice in Ukraine and its further improvement were considered.

The impact of visual complexity on perceived safety and comfort of the users: A study on urban streetscape of Sri Lanka.

Increase in the variety of development in urban context has made it more complicated and complex for the users of public spaces. Absence of sufficient information to read the surrounding causes psychological anxiousness leading to perceived danger or discomfort for the urbanites. Consequently, perceived safety and comfort of the users is distinctively low in urban contexts, creating neglected and underused spaces. Complexity is one of the information processing variables as per Kaplan and Kaplan’s informational model which helps users to comprehend the surrounding environment. The streetscape plays a vital role in the daily movement patterns within the urban cities and is the transition boundary between the public and private realms. Visual complexity of these streets is a result of different configurations of elements within the urban areas. This research is conducted to ascertain the relationship between visual complexity levels of the streets with the perceived safety and comfort of the users. Shannon Diversity Index (SDI) and Fractal dimension analysis were conducted with 48 SVIs (Street View Images) selected within 1km radius of Colpetty junction, Colombo Sri Lanka covering all the possible compositions found within the context. The visual index data extraction had identified ten major components within the selected 48 SVIs. 78 subjective ranking responses for perceived safety, comfort (preference) and perceived complexity were collected from snowball sampling. Findings of the study revealed that perceived safety levels and preference scores for the SVIs are related to the Shannon Diversity Index calculation in an inverted ‘U’ shape where the highest and lowest SDI values are related with low preference scores and low safety levels. The SVIs with medium SDI values are perceived as the safest and most preferred by the users of urban streets of Colombo Sri Lanka. The SDI and fractal dimension values were significantly correlated with the perceived complexity scores of the users. The results of this study can be accommodated in the planning and designing of urban streetscapes of tropical climates for sustainable and friendly urban expansions.

Safe Assets at Financial Globalization

The paper explores the impact of safe assets on the economic growth on the financial globalization context. The method employs both cross-section and panel data regression on a data sample of 148 economies, both advanced and developing ones, over the 1990–2019 period. The robustness analysis is carried out by controlling for different sub-sampling data, including advanced economies compared with emerging and developing economies, and 3 consecutive 10-year periods from 1990 to 2019. The empirical evidence establishes an inverted-U-shaped dependence pattern of economic growth on the assets safety, measured by the sovereign debts rating. The economic growth is first increasing then decreasing on the assets safety, with the turning point being the value at 12.0 of sovereign debts rating. Thus, the assets safety only exerts a positive impact on the economic growth for the low safety level.

Application of Intumescent Coating for Increasing Fire-Resistance Values of Cable Products

The results of experimental studies on the effectiveness of insulation of electrical cables with fire-resistant coating are presented. Analysis of methods of cables products using shows a steady trend of increasing their using during the arrangement of premises. Fires and rapid spread of flame are possible during the exploitation of such structures. Statistics of cable products show a low level of safety due to using of combustible insulation, which is highly sensitive to high temperatures and fire. After the test, it is seen that the specimen of the cable without a fire-resistant coating supports self-combustion for more than 30 s, and the damage to the specimen is more than 100 mm. After testing the specimen with a fire-resistant coating, it is seen that the cable specimen doesn’t support self-combustion, and the damage to the specimen isn’t more than 40 mm. Inhibition of the process of ignition and propagation of flame for such specimen is associated with the decomposition of flame retardants under the action of temperature, which occurs with heat absorption and release of non-combustible gases (nitrogen, carbon dioxide), as well as changing the direction of decomposition towards non-combustible gases and flame retardant coke residue. This leads to an increase of the thickness of the coke layer and inhibition of heat transfer of high-temperature flame to the insulation material, which indicates the possibility of transition of combustible insulation of the cable with a fire-resistant coating to non-flammable materials, which aren’t spread a flame.

Application of Coating for Fire Protection of Textile Structures

The results of experimental research on the effectiveness of fire protection of easily erected structures made of flammable textile products are presented. Analysis of the use of structures made of flammable textile products, which are easy to build, shows a steady trend to increase their use during the temporary implementation of certain tasks of the Armed Forces of Ukraine and SES units. During the heating of such buildings, fires and rapid spread of fire are possible. Statistics on the operation of easily erected structures have shown a low level of safety due to the use of natural fibers (such as flax, cotton and mixtures), which are highly sensitive to high temperatures and fire. After the test, it is seen that the raw sample of textile material supports self-combustion for more than 5 s, the damage to the sample is more than 200 mm. After testing the flame retardant sample, it is seen that the sample of textile material does not support self-combustion; damage to the sample not more than 40 mm. Inhibition of the process of ignition and spread of flame for such a sample is associated with the decomposition of flame retardants under the action of temperature with heat absorption and release of non-combustible gases (nitrogen, carbon dioxide), changing the direction of decomposition towards non-combustible gases and flame retardant coke. This leads to an increase in the thickness of the coke layer and inhibition of heat transfer of high temperature flame to the material, which indicates the possibility of transition of textile materials when treated with a flame retardant composition to materials related to non-combustible surfaces that do not spread flame.

Classification of hotels taking into account fire risks

Introduction. The current Russian Regulation on classification of hotels hardly takes into account their fire safety conditions. The system, adopted in the Regulation, provides for an expert scoring assessment of hotel parameters for their assignment to a certain category (star rating). The purpose of the article is to develop methods that allow determining the level of fire safety of hotels in points commensurate with the accepted rating system, for its further use in the course of assignment of appropriate categories to hotels. Theoretical fundamentals of scoring methods of assessment of fire safety of hotels. Three approaches to the calculation of «fire points» of hotels have been developed, based on the breakdown of hotels into classes and identification of the fire safety index of hotels within one class. The first scoring method is the Gretener method used for calculating the integral fire safety index. The first and third quartiles are identified for the hotel statistics. Hotels, whose index does not exceed the first quartile, belong to the subgroup featuring a high level of fire safety; those ranging from the first (inclusively) to the third quartile belong to the medium level. If the values of the fire hazard index of hotels are not smaller than the third quartile, they belong to the subgroup that has a low level of fire safety. The second method is based on the use of a «safety reserve» in terms of evacuation time. The third model of assessing the fire hazard of hotels includes the breakdown of hotels into groups, identification of the value of individual fire risk, ranking hotels by the fire risk that varies from the lowest to the highest.Results and their discussion. As for the classification of hotels, problems that accompany the consolidation of the physical approach to the fire hazard assessment with the expert method of scoring are solved by choosing the proportion between the points of the system and the «fire points» set by the adjustment coefficient. The fire points, assigned to the subgroups of hotels, are indicative and should be corrected within the framework of the proposed approach.Conclusions. The experimental application of the developed methods using the cases of real hotel facilities will allow choosing the optimal engineering method of taking into account the fire safety of hotels in the process of their classification.

Experience and results after the implementation of a radiology day unit in a reference hospital

BackgroundInterventional radiological procedures have significantly increased in recent years. Most of them are minimally invasive and require a short hospitalization, mainly done in other non-radiological units nowadays. Limited bed availability and high occupancy rates in these units create longer waiting lists and cancellations. The aim of this retrospective study is to assess the creation and functioning of a Radiology Day Unit (RDU) and evaluating its outcomes. For this purpose, data about interventional procedures and its complications, incidents, patient safety, quality and satisfaction rates were collected from May 2018 to December 2020, and posteriorly analyzed to evaluate its implementation.ResultsDuring the assessed period, 3841 patients were admitted into the RDU, with a net increase of 13% and 26% in the second and third year, respectively. Procedures performed by the Abdominal Radiology section were the most frequent (76–85%) followed by Interventional Vascular Radiology and Thoracic Radiology. Complication rates were low (1.5%) and most of them were self-limited and managed in the own department. Waiting lists were significantly reduced, from 2 months to 1 week in case of procedures performed by the Abdominal Radiology section. Patient satisfaction was higher than 80% in all the items evaluated with a global satisfaction of 93%.ConclusionThe RDU in our hospital has become a vital section for the management and post-procedure caring of patients undergoing interventional procedures in the Radiology Service with low complication rates and overall high levels of quality and patient safety, allowing the reduction of waiting lists and occupancy rates.
