Incontinencia urinaria en trabajadoras de la salud como factor predisponente de presentismo en Chile: estudio exploratorio de método mixto / Urinary incontinence in health workers as a predisposing factor for presenteeism in Chile: A mixed-methods exploratory study

Introducción La incontinencia urinaria impacta de forma negativa la calidad de vida de quienes la padecen y puede perjudicar las actividades laborales, siendo causante de presentismo en las profesionales de salud. Esto puede implicar la disminución en la calidad de la atención y seguridad de la/el paciente. El objetivo del presente estudio es explorar la autopercepción de las trabajadoras de salud que padecen incontinencia urinaria como factor predisponente de presentismo. Métodos Estudio mixto de carácter exploratorio-descriptivo. La muestra fue seleccionada de forma no probabilística e intencionada por criterio y conveniencia con un tamaño de 14 voluntarias, considerando la saturación de la información. Para el proceso y análisis de datos temáticos se consideraron los criterios de confiabilidad definidos por Guba. Resultados Muestra con edad media de 38,9 + 7,1 años y un puntaje de SPS-6 medio de 15,8 + 3,5 puntos, mostrando mayor alteración en la dimensión de evitar la desconcentración. Las narrativas presentes en el caso estudiado aportaron información relevante de cómo la incontinencia urinaria afecta el desempeño laboral de las trabajadoras de salud a través de la interrupción en su jornada, disminución en la calidad de la atención clínica, como también el aumento de su ansiedad respecto a su entorno. Conclusiones Dado que la incontinencia urinaria y el presentismo son experiencias subjetivas y multidimensionales, al igual que el efecto negativo en el desempeño laboral, se recomienda un estudio que permita identificar variables predictoras y las pérdidas económicas asociadas a esta condición. Con ello se buscaría establecer mejoras en el ambiente laboral, así como en el autocuidado de funcionarias, procurando mayores beneficios y mejores niveles de eficiencia en la organización.

Introduction Urinary incontinence negatively impacts the quality of life and can harm work activities, causing presenteeism in health professionals and decreasing the quality of care and patient safety. The objective of this study is to explore the self-perception of health workers who suffer from urinary incontinence as a predisposing factor for presenteeism. Methods Mixed study of an exploratory-descriptive nature. The sample was selected in a non-probabilistic and intentional way by criterion and convenience with a size of 14 volunteers, considering the saturation of the information. Reliability criteria defined by Guba for the process and analysis of thematic data were considered. Results The sample had a mean age of 38.9 + 7.1 years and a mean SPS-6 score of 15.8 + 3.5 points, showing alteration in the dimension of avoiding deconcentration. The narratives in the case study provide relevant information on how urinary incontinence affects the work performance of health workers through the interruption in their day, decreases the quality of clinical care, and increases their anxiety regarding their environment. Conclusions Urinary incontinence and presenteeism are subjective, and multidimensional experiences affect work performance. Therefore, further studies are recommended to identify predictor variables and the economic losses associated with this condition to establish improvements in the work environment and the self-care of female employees seeking greater benefits and better levels of efficiency in the organization

Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Assessment of Efficiency of Bioactive Glass, Self-Assembling Peptide, and Ozone Remineralising Agents on Artificial Carious Lesion

ABSTRACT Objective: To assess the efficacy of bioactive glass, self-assembling peptide, and ozone-remineralizing agents on the artificial carious lesion. Material and Methods: On the extracted 60 premolar teeth, an artificial carious lesion/demineralization was created. Later, the remineralization of demineralized teeth was done with respective remineralizing agents (Group A: Calcium sodium phosphosilicate (bioactive glass), Group B: Self-assembling peptide, Group C: Ozone remineralizing agents and Group D (Control): De ionized water. The degree of demineralization and remineralization were evaluated using the Vickers Hardness Number. Results: There was a decrease in microhardness from baseline to demineralization in all the groups, and this reduction was found to be statistically considerable. After the remineralization of demineralized samples with respective remineralizing agents, there was an increase in microhardness of 312.38, 276.67, and 254.42 in groups A, B, and C, respectively. In contrast, in Group D, there were no changes. Conclusion: Bioactive glass and self-assembling peptides had higher remineralizing capacities, which can be used to treat early carious lesions.

Reproduction technologies in pig farming: artificial insemination - literature review / Tecnologias de reprodução na suinocultura: inseminação artificial - revisão de literatura / Tecnologías de reproducción en la porcicultura: inseminación artificial - revisión de literatura

This summary addresses the use of reproduction technologies in swine farming, with an emphasis on artificial insemination (AI). Brazilian swine farming has been growing significantly and seeks new technologies to achieve high productive indices sustainably and competitively. Pigs present favorable characteristics such as high prolificacy, fertility, rapid growth, feed efficiency, and carcass yield, which has led to intensive development of the activity with advanced genetic selection. AI is widely employed to disseminate genetic material among different regions and farms. Several AI techniques are used in modern swine farming: intrauterine insemination (IUI) allows semen deposition in the uterine region, reducing costs; fixed-time insemination (FTAI) synchronizes estrus in various females, facilitating management and increasing efficiency; deep intrauterine insemination (DIUI) deposits semen in the uterine horns, obtaining better results; and cervical insemination (CI), a traditional technique widely used, although it may be more time-consuming and present higher reflux rates. The success of AI is related to knowledge of the reproductive cycle of sows, proper nutrition, and genetic and environmental factors. Semen quality is essential, requiring collection by trained professionals and evaluation of sperm motility and morphology. Although it is a consolidated technique, there are issues to be further explored to optimize its application, defining the exact moment for insemination, reducing reflux, and adopting effective protocols. AI is an essential tool for the growth of Brazilian swine farming, but it requires continuous studies to maximize its efficiency and results, considering the farm's production goal and the size of the enterprise to achieve high reproductive and productive indices.

Eficiência em saúde pública: a trajetória de um conceito proveniente da engenharia / Efficiency in public health: the trajectory of a concept from engineering

RESUMO A temática mais geral desta pesquisa diz respeito à eficiência na administração pública e sua manifestação na saúde pública. Em um contexto neoliberal, marcado por políticas de austeridade, em que as restrições orçamentárias em relação às políticas sociais são um dos aspectos principais, a análise sobre o que significa eficiência torna-se uma questão de pesquisa relevante. As diferentes ideias sobre eficiência, constituídas e modificadas ao longo da história, exercem influência na gestão dos recursos públicos. Neste sentido, este artigo tem como objetivo descrever a trajetória de desenvolvimento do conceito de eficiência na administração pública, mais especificamente na área de saúde pública. Para alcançar este objetivo, foi realizado um ensaio teórico, no qual desenvolve-se um argumento teórico-analítico destinado a orientar pesquisas empíricas em relação ao tema da eficiência na gestão em saúde. Este argumento é baseado em três pressupostos: ao longo de um século de desenvolvimento do conceito de eficiência na administração pública, este conceito ainda é fortemente carregado de pressupostos oriundos da engenharia; esses pressupostos, por sua vez, se conectam diretamente com princípios da economia neoclássica, que estão na base de perspectivas neoliberais aplicadas à gestão pública; e na área da saúde, o conceito de eficiência fundado apenas em pressupostos da economia de mercado é insuficiente, necessitando ser articulado aos conceitos de eficácia e efetividade.

ABSTRACT This article aims to describe the development trajectory of the concept of efficiency in public administration, more specifically in the area of public health. To achieve this objective, a theoretical essay was carried out, in which a theoretical-analytical argument was developed to guide empirical research in relation to the issue of efficiency in health management. This argument is based on three assumptions: over a century of development of the concept of efficiency in public administration, this concept is still heavily loaded with assumptions from engineering; these assumptions, in turn, are directly connected with principles of neoclassical economics, which underlie neoliberal perspectives applied to public management; and in the health area, the concept of efficiency based only on market economy assumptions is insufficient, needing to be articulated with the concepts of efficacy and effectiveness.

Satisfacción del usuario en la atención odontológica comunitaria en Reynosa, Tamaulipas / User ́s satisfaction of community dental care in Reynosa,Tamaulipas

Resumen Objetivo: Evaluar el nivel de satisfacción en la atención recibida por los usuarios de la Clínica Odontológica de la Universidad México Americana del Norte (CO-UMAN) Allende. Material y método: El estudio fue descriptivo, observacional, transversal y prospectivo; se aplicó una encuesta de opinión a 200 pacientes, seleccionados mediante muestreo por conveniencia en 2019, sobre la estructura, proceso y resultados de la atención; así como bio-demográficos de cada paciente. Resultados: Predominaron pacientes con edades entre 21 y 60 años (71%), mujeres (63%), casados(as) (45%), empleados(as)/amas de casa (57%) y baja frecuencia de enfermedades concomitantes (10%). A mayor edad hubo mayor frecuencia de enfermedades concomitantes (r=0.26; p<0.05) y satisfacción en el servicio (r=0.26; p<0.05); con otras enfermedades concomitantes la satisfacción del paciente fue menor (r=-0.39; p<0.05). Los pacientes indican que hay más satisfacción (de 2.6 a 5.4 veces) al recibir un servicio adecuado o mejor. La satisfacción del paciente y la calidad de la atención de la clínica se asoció positivamente (p<0.05) con los trámites sencillos, trato por parte del odontólogo; confianza en la calidad de los servicios recibidos; relación costo/beneficio; puntualidad en la atención y efectividad del tratamiento odontológico recibido. Los coeficientes canónicos estandarizados indicaron mayor contribución en la satisfacción del usuario: las instalaciones e infraestructura de la clínica (0.479); atención del personal y proceso administrativo (0.543); atención del odontólogo (0.700); confianza en la atención y percepción del servicio recibido (0.660) y pobre relación con edad (0.078), género (0.030), estado civil (-0.040) y ocupación del paciente (0.065). Conclusión: No obstante que la cantidad y calidad del servicio de la CO-UMAN se ha incrementado y mejorado sustantivamente, es necesario desarrollar un plan de mejora continua para alcanzar estándares de calidad total.

Abstract Objective: To evaluate the level of satisfaction in the care received by the users of the Dental Clinic of the Universidad México Americana del Norte (DC-UMAN) Allende. Material and method: The study was descriptive, observational, cross-sectional, and prospective. In 2019, an opinion survey on the structure, proceedings, and results of the care, as well as bio-demographics of each patient was applied to 200 patients selected by convenience sampling. Results: Patients aged between 21 and 60 years (71%), women (63%), married (45%), employees/housewives (57%) and a low frequency of concomitant diseases (10%) predominated. At an older age, there was a higher frequency of concomitant diseases (r=0.26; p<0.05) and satisfaction in the service (r=0.26; p<0.05); with other concomitant diseases, patient satisfaction was lower (r=-0.39; p<0.05). Patients indicated that there is more satisfaction (from 2.6 to 5.4 times) when receiving an adequate or better service. Patient satisfaction and the quality of clinic care were positively associated (p<0.05) with simple procedures, treatment by the dentist, confidence in the quality of the services received, cost-benefit ratio, punctuality in the care and effectiveness of the dental treatment received. The standardized canonical coefficients indicated a greater contribution to user satisfaction from the facilities and infrastructure of the clinic (0.479), staff attention and administrative process (0.543), dental care (0.700), trust in care and perception of the service received (0.660) and poor relationship with age (0.078), gender (0.030), marital status (-0.040), and occupation (0.065) of the patient. Conclusion: Although the quantity and quality of the DC-UMAN service has increased and improved substantially, it is necessary to develop a continuous improvement plan to achieve total quality standards.

Estimación de la eficiencia del uso de pabellones electivos en el sistema de salud público chileno entre 2018 y 2021 / Efficiency estimation on the use of elective surgical theaters in the Chilean public health system from 2018 to 2021

Objective The efficient use of wards intended for elective surgeries is essential to resolve cases on the surgical waiting list. This study aims to estimate the efficiency of ward use in the Chilean public health system between 2018 and 2021. Methods The design was an ecological study. Section A.21 of the database constructed by the monthly statistical summaries that each public health network facility reported to the Ministry of Health between 2018 and 2021 was analyzed. Data from subsections A, E and F were extracted: ward staffing, total elective surgeries by specialty, number and causes of suspension of elective surgeries. Then, the surgical performance during working hours and the percentage of hourly occupancy for a working day was estimated. Additionally, an analysis was made by region with data from 2021. Results The percentage of elective wards in use ranged from 81.1% to 94.1%, while those enabled for those staffing ranged from 70.5% to 90.4% during 2018 and 2021. The total number of surgeries was highest in 2019 (n = 416 339), but for 2018, 2020, and 2021 it ranged from 259 000 to 297 000. Suspensions varied between 10.8% (2019) and 6.9% (2021), with the leading cause being patient-related. When analyzing the number of cases canceled monthly by facility, we saw that the leading cause was trade union-related. The maximum throughput of a ward intended for elective surgery was reached in 2019 and was 2.5 surgeries; in 2018, 2020 and 2021, the throughput borders on two surgeries per ward enabled for elective surgery. The percentage of ward time occupied during working hours by contract day varies between 80.7% (2018) and 56.8% (2020). Conclusions All the parameters found and estimated in this study show that there is an inefficient utilization of operating rooms in Chilean public healthcare facilities.

Objetivo El uso eficiente de pabellones destinados a cirugías electivas es fundamental para resolver patologías en lista de espera quirúrgica. El objetivo general de este estudio es estimar la eficiencia del uso de pabellones en el sistema de salud público de Chile entre los años 2018 y 2021. Métodos El diseño fue un estudio ecológico. Se analizó la Sección A.21 de la base de datos construida por los resúmenes estadísticos mensuales que cada establecimiento de la red de salud pública reportó al Ministerio de Salud de Chile entre 2018 y 2021. Se extrajeron los datos de la subsección A, E y F: dotación de pabellones, total de cirugías electivas por especialidad, número y causas de suspensión de cirugías electivas. Luego se estimó el rendimiento quirúrgico en horario hábil y el porcentaje de ocupación horaria respecto de una jornada laboral. Adicionalmente, se hizo un análisis por región con datos de 2021. Resultados El porcentaje de pabellones electivos respecto de los en dotación varió entre 81,1 y 94,1%; mientras que los habilitados respecto de los en dotación varió entre 70,5 y 90,4% durante 2018 y 2021. El número total de cirugías fue más alto en 2019 (n = 416 339), pero en 2018, 2020 y 2021 variaron entre 259 y 297 mil cirugías. Las suspensiones varían entre 10,8 (2019) y 6,9%w(2021), siendo la principal causa de suspensión atribuida al "paciente". Al analizar la cantidad de pacientes suspendidos mensualmente por institución, se observa que la principal causa es "gremial". El rendimiento máximo de un pabellón destinado a cirugía electiva se alcanzó en 2019 y fue de 2,5 cirugías; mientras que en 2018, 2020 y 2021 el rendimiento bordea las dos cirugías por pabellón habilitado para cirugía electiva. El porcentaje de tiempo de pabellón ocupado en horario hábil respecto a una jornada de contrato varía entre 80,7 (2018) y 56,8% (2020). Conclusiones Todos los parámetros encontrados y estimados en este estudio muestran que el uso de pabellones en el sistema público de Chile es ineficiente.

Objective: To compare the efficiency of two coral garden structures in the growth of the species Acropora cervicornis in Huertas Bay, Portobelo National Park, Colon Panama. Methods: Two fixed-type structures were placed, using PVC together with hydraulic concrete bases, and two clothesline-type structures, using PVC and nylon thread. The coral fragments that were placed in the structures came from Bahía Huertas and Buenaventura Island. The growth of the corals was determined using the linear growth and tissue extension measurement method. Results: A total of 80 coral fragments were planted, representing an estimated extension of 9.71 m of coral in Huertas Bay. After nine months of study, a total of 15.3 m of totally new coral (1 525.6 cm) was estimated, where only 4.6 % belonged to the fragments of the fixe-type structure, while 95.4 % belonged to the clothesline-type structure. Conclusions: The clothesline-type structure was the most efficient and viable within the study, with better survival and growth rate compared to the fixed type structure, where it did present a mortality of 45 %.

Analysis of operation efficiency and resource allocation of clinical departments in a hospital based on data envelopment andlysis / 中华医院管理杂志

Objective:To establish a calculation model for the operational efficiency and resource allocation of clinical departments in hospitals, for references for hospitals to optimize resource allocation.Methods:The informations including hospitalization time, nursing grade, etc. of inpatients admitted by 32 clinical departments in a tertiary public hospital from January to December in 2021 were extracted. A data envelopment analysis method was conducted on the operation efficiency and input edundancy of the departments. The K-means algorithm was used to divide inpatients into 3 categories according to the level of medical workload. Taking the numbers of doctors, nurses and beds as the input indicators, and the numbers of patients in the 3 categories as the output indicators, a BCC model 1 was established to evaluate the efficiency of resources invested by clinical departments into professional human value. At the same time, a BCC model 2 was established with the total number of patients admitted and medical income as the output indicators to evaluate the efficiency of resources invested by clinical departments into economic benefits.Results:A total of 38 147 inpatients were enrolled. There were 14 departments with overall technical efficiency (OTE) =1.000 in the BCC model 1, 10 departments with OTE=1.000 in the BCC model 2, and 8 departments with OTE=1.000 in the 2 models. As for the input redundancy, 6 departments had high input redundancy in the BCC model 1, 11 departments had high input redundancy in the BCC model 2, and 4 departments had high input redundancy in both models.Conclusions:The model established by this study could effectively evaluate the operational efficiency and input redundancy of clinical departments, identify departments with high workload and low economic benefits, and provide reference for the rational allocation of medical resources in hospitals.

Research on the allocation efficiency of primary medical and health institutions in China based on data envelopment analysis / 中华医院管理杂志

Objective:To analyze the input and output status of health resources in primary medical and health institutions and their allocation efficiency in different regions of China, and to provide an empirical basis for optimizing the allocation of primary medical and health resources in China among regions.Methods:The input index data (number of beds and number of health personnel) and output index data (number of primary medical and health institutions visits, number of family health services, number of hospital admissions) of primary medical and health institutions in China in 2020 were extracted from the China Health Statistical Yearbook 2021. Based on the BCC ( Banker, Charnes, Cooper) model of data envelopment analysis ( DEA), the Bootstrap- DEA method was used to correct bias, the allocation efficiency of primary medical and health resources in 31 provinces was calculated and the regional differences were analyzed. Results:After bias correction, the technical efficiency (TE) of resource allocation in primary medical and health institutions decreased by 0.102. The average TE score of all 31 primary medical and health institutions was 0.669, indicating a serious problem of ineffective use of technology. The TE of the eastern, central and western regions was 0.694, 0.663, and 0.649 respectively. There was obvious polarization in the central regions.Further analysis of the efficiency improvement of non DEA efficient provinces showed that 2 DEA weakly efficient provinces and 16 DEA ineffective provinces had several reference provinces for efficiency configuration improvement; The provinces that have been referenced more than 10 times were Zhejiang, Chongqing, Sichuan, and Ningxia, while the provinces that were listed as the first reference by other provinces were Ningxia, Chongqing, Zhejiang, and Tibet.Conclusions:The resource allocation efficiency of primary medical and health institutions in China is relatively low, and regional differences are obvious. The balance between different inputs and outputs should be considered when allocating the resources. Non DEA effective provinces can use DEA analysis to find the most suitable reference object and make reference improvements in the short term.

Among them, 213 hospitals (48.2%) were in a decreasing state of returns to scale, 54 hospitals (12.2%) were in a constant state of returns to scale, and 175 hospitals (39.6%) were in an increasing state of returns to scale; Out of the 45 tertiary hospitals, 42 (93.3%) were in the stage of diminishing returns to scale, while 226 (56.9%) of 397 secondary and lower hospitals were in a state of constant or increasing returns to scale.Conclusions:The utilization efficiency of medical resources in public TCM hospitals in Gansu province is relatively low, and there is a significant gap between different levels of TCM hospitals.

Efficiency analysis and management strategies of hospital beds based on diagnosis-related groups / 中华医院管理杂志

Objective:To improve the evaluation method of hospital beds efficiency based on diagnosis-related groups (DRG), and to provide a basis for hospitals to allocate beds reasonably and improve bed efficiency.Methods:Taking a tertiary hospital in Beijing as the research object, the types of beds were evaluated by the beds utilization matrix with the time consumption index as the X-axis and the bed utilization rate as the Y-axis. The types of beds in the department were divided into efficiency type, pressure type, turnover type, and idle type. The efficiency of medical services and the level of diagnosis and treatment were evaluated by the weight of DRG per bed. The calculation method of theoretical number of beds was improved by incorporating hospital case mix index as a risk adjustment factor into the formula to evaluate the status of beds allocation. Combining the bed type, DRG weight per bed, and bed allocation status, the improvement emphasis and management strategy of bed utilization could be comprehensively analyzed.Results:Among the 24 departments in the hospital, there were 5, 9, 1 and 9 departments being efficiency type, pressure type, turnover type and idle type, respectively. The weight per bed of 11 departments was higher than the average level of the hospital. There were 16, 5, and 3 departments with appropriate, fewer, and excessive beds, respectively.Conclusions:The comprehensive analysis of beds utilization type, allocation status and weight of each bed based on DRG is an effective method to evaluate the efficiency of hospital beds, and can provide decision-making basis for hospital bed resource allocation, hospital operation focus adjustment, and subject development planning.
