Conclusión: se presentan hallazgos de validez y confiabilidad que sustentan el uso de dos versiones reducidas de la escala ASA en adolescentes.

Introduction: This study aimed to investigate the validity and reliability of the Spanish version of the Appraisal of Self-care Agency Scale (ASA scale) in adolescents. Materials and methods: A questionnaire was created with 24 items of the ASA scale together with items that explored the sociodemographic variables as well as health-related behaviors and conditions. The questionnaire was given to 541 Mexican adolescents. Different analysis techniques were performed, including exploratory factor analysis, confirmatory factor analysis (CfA), determination of internal consistency (coefficients α and ω), and other variables relationship based on group comparisons. The performance of the different factorial structures of the ASA scale was analyzed. Results: We obtained two proposals based on the ASA Scale that can be used in adolescents; one was based on a one-dimensional model (20 items) and the other was based on a three-factor model (14 items). These proposals performed well in the CfA as well as in internal consistency analysis techniques. Furthermore, these proposals presented validity evidence based on the relationship with health-related behaviors and conditions. Conclusion: We provide evidence for the validity and reliability of the two reduced versions of the ASA scale that supports its use in adolescents.

Bioinformatics in Mexico: A diagnostic from the academic perspective and recommendations for a public policy.

In this work, we present a diagnostic analysis of strengths, weaknesses, opportunities and threats (SWOT) of the current state of Bioinformatics in Mexico. We conducted semi-structured interviews among researchers and academics with key expertise in this field, identified by bibliometric analyses and qualitative sampling techniques. Additionally, an online survey was conducted reaching a higher number of respondents. Among the relevant findings of our study, the lack of specialized human resources and technological infrastructure stood out, along with deficiencies in the number and quality of academic programs, scarce public investment and a weak relationship between public and private institutions. However, there are great opportunities for developing a national Bioinformatics to support different economic sectors. In our opinion, this work could be useful to favor a comprehensive network among Mexican researchers, in order to lay the foundations of a national strategy towards a well designed public policy.

A Socio-technical Approach to Evaluating an Electronic Medical Record System implemented in the Public Health Services of Aguascalientes / Una Aproximación Socio-técnica a la Evaluación de un Expediente Médico Electrónico implementado en Servicios de Salud Públicos de Aguascalientes

Abstract The objective of this study was to explore a strategy for evaluating an Electronic Medical Record (EMR) system implemented in the public health services of Aguascalientes, Mexico. A questionnaire based on DeLone and McLean's Model of Information Systems Success (MISS) was adapted to Spanish and applied with 62 primary care physicians working in health centers of the Instituto de Servicios de Salud del Estado de Aguascalientes (ISSEA or the State of Aguascalientes Institute for Health Services). Opportunities for improving EMR systems were also explored from the informants' perspectives. Additionally, the relationships between MISS components were analyzed using Structural Equations Modeling (SEM). Some MISS components and particular items (service quality and overall satisfaction) presented low averages, reflecting opportunities for improving the development and implementation of EMR, such as the need to continuously update information pertaining to diagnostic and medicine catalogs and develop systems that are interoperable between the second and third levels of care. In conclusion, the present study contributes generating evidence on the use of the MISS to evaluating EMR systems in public health services of Mexico. More evidence should be generated in this field in order to promote the continuous improvement of these information systems.

Resumen El objetivo de este estudio fue explorar una estrategia para la evaluación de un Expediente Clínico Electrónico (ECE) implementado en servicios de salud públicos de Aguascalientes, México. Se adaptó al español un cuestionario basado en el Modelo de Éxito de Sistemas de Información (MISS) de DeLone y McLean y se aplicó a 62 médicos de atención primaria que trabajan en centros de salud del Instituto de Servicios de Salud del Estado de Aguascalientes (ISSEA). Se exploraron también las oportunidades de mejora del ECE desde la perspectiva de los informantes. Además, se analizaron las relaciones entre los componentes del MISS mediante el modelado de ecuaciones estructurales (SEM). Algunos componentes del MISS e items particulares mostraron promedios bajos (p.ej., calidad del servicio y satisfacción) que reflejan algunas oportunidades de mejora en el desarrollo e implementación del ECE, como la necesidad de una actualización continua de la información sobre diagnósticos y catálogos de medicamentos; y el desarrollo de sistemas de interoperabilidad con el segundo y tercer nivel de atención. En conclusión, el presente estudio contribuye en la generación de evidencia sobre el uso del MISS para evaluar los sistemas de EMR en servicios de salud públicos de México. Se debe generar más evidencia en este campo para promover la mejora continua de estos sistemas de información.

Salud electrónica (e-Salud): un marco conceptual de implementación en servicios de salud.

Electronic health (e-Health) is a broad concept that involves the application of information and communication technologies to systems for surveillance, prevention, promotion and health care. e-Health components mainly include supply and resource management systems (appointment schedules, clinical laboratory or pharmacy), electronic medical records, electronic prescription, clinical decision support systems, use of mobile devices, imaging systems, remote care systems, as well as teaching through digital media. Other components that can be regarded as part of e-Health are the massive data storage and analysis systems, artificial learning, as well as "internet of things" systems. In this work, a conceptual framework is proposed in order to analyze the implementation of e-Health components and their effects on the quality of health services provision.

La salud electrónica (e-Salud) es un concepto amplio que implica la aplicación de las tecnologías de la información y la comunicación en los sistemas de vigilancia, prevención, promoción y atención a la salud. Como componentes de la e-Salud se incluyen principalmente los sistemas de administración de insumos o recursos (agenda de citas, laboratorio clínico o farmacia), el expediente clínico electrónico, la prescripción electrónica, los sistemas de apoyo a la decisión clínica, el uso de dispositivos móviles, los sistemas de imagenología, los sistemas de atención a distancia, así como la enseñanza a través de medios digitales. Otros componentes que pueden considerarse parte de la e-Salud son los sistemas de almacenamiento y análisis masivo de datos, el aprendizaje artificial y los sistemas de "internet de las cosas". En este trabajo se propone un marco conceptual para analizar la implementación de componentes de e-Salud y sus efectos en la calidad de la provisión de servicios de salud.

A review of fundamental topics in health systems / Revisión de temas fundamentales en sistemas de salud

Health systems are dynamic complex structures, whose main aim is to satisfy health needs of populations. According to the World Health Organization, health systems put together four key functions: 1) stewardship-governance, 2) financing, 3) resources generation, and 4) provision of health services to meet three key objectives: to maintain or improve population health conditions, to offer better response time, and to provide financial protection to the population that demands health services. The objective of this article was to carry out a conceptual review of two basic functions: stewardship-governance on one hand, and financing on the other. Two essential attributes in the provision of health services were also reviewed: quality and equity. Finally, a conceptual model for quality analysis in the provision of health services is proposed.

Los sistemas de salud son estructuras complejas en constante dinamismo que tienen por objetivo principal satisfacer las necesidades de salud de la población. De acuerdo con la Organización Mundial de la Salud en los sistemas de salud se articulan cuatro funciones básicas: 1) rectoría y gobernanza, 2) financiamiento, 3) generación de recursos y 4) provisión de servicios de salud. Estas funciones permiten cumplir con tres objetivos fundamentales: mantener o mejorar las condiciones de salud de la población, ofrecer buena capacidad de respuesta ("trato adecuado") y brindar protección financiera a la población que demanda servicios de salud. El objetivo de este trabajo fue hacer una revisión conceptual de dos funciones básicas: la rectoría y la gobernanza por un lado y por el otro, el financiamiento. También se revisan dos cualidades esenciales en la provisión de servicios de salud: la calidad y la equidad. Finalmente, se presenta una propuesta de modelo conceptual para el análisis de calidad en la provisión de servicios de salud.

Análisis de desigualdades en el trato adecuado en las Unidades de Atención Primaria de los Servicios Estatales de Salud de México / Analysis of inequalities in the appropriate treatment in the Primary Care Units of the State Health Services of Mexico

Resumen Objetivo: Analizar desigualdades en el trato adecuado en la atención a pacientes sin seguridad social que utilizan servicios de salud ambulatorios en las Unidades de Atención Primaria (UAP) de los servicios estatales de salud de la Secretaría de Salud, en México. Métodos: Se trata de un diseño transversal y ecológico que plantea como unidades de análisis las entidades federativas de México. Se utilizaron datos de tiempo de espera y percepción de calidad en la atención que reportaron los usuarios en la Encuesta Nacional de Salud y Nutrición (ENSANUT) 2012. Se plantearon algunos Indicadores de Trato Adecuado (ITA), y se calcularon indicadores de desigualdad sugeridos en la literatura. Asimismo, se recopilaron de la literatura Indicadores Proxy de Determinantes Sociales de la Salud (IPDSS) con fines de analizar la posible asociación entre ITA e IPDSS a través de análisis de correlación y regresión (índice de efecto). Resultados: Se identificaron desigualdades en los ITA planteados entre las entidades federativas de México, principalmente en los indicadores de tiempo de espera (disparidad absoluta 52.7 min y disparidad relativa 1.9 para la media estatal en tiempo de espera). Asimismo, se identificaron asociaciones significativas entre ITA e IPDSS. Particularmente, se encontró asociación entre todos los ITA propuestos y la tasa estatal de UAP, aunque con débil índice de efecto. Conclusiones: Persisten desigualdades en el trato adecuado durante la prestación de servicios ambulatorios a población sin seguridad social. Es necesario trabajar más en subsanar desigualdades y promover la equidad en salud.

Abstract Objective: To analyze responsiveness inequalities in the care of patients without social security that use outpatient health services in the Primary Care Units (PCU) of the state health services of the Ministry of Health in Mexico. Methods: It is a cross-sectional and ecological design that considers the federative entities of Mexico as units of analysis. Users reported time-out and quality perception data were used from the National Health and Nutrition Survey (ENSANUT). Some Responsiveness Indicators (RI) were proposed, and suggested inequality indicators were calculated. Likewise, proxy Indicators of Social determinants of Health (IPDSS) were collected from the literature to analyze possible association between ITA and IPDSS through correlation and regression analysis (effect index). Results: Inequalities in ITAs were identified among the federative entities of Mexico, mainly in the indicators of waiting time (absolute disparity 52.7 min and relative disparity 1.9 for the state average in waiting time). Likewise, significant associations between ITA and IPDSS were identified. In particular, we found association between all the proposed ITAs and the state rate of PCU, although with a weak effect index. Conclusions: Inequalities persist in the responsiveness during the provision of outpatient services to the population without social security. More work is needed to address inequalities and promote equity in health.

Cost-effectiveness study of oral hypoglycemic agents in the treatment of outpatients with type 2 diabetes attending a public primary care clinic in Mexico City.

INTRODUCTION: Worldwide, diabetes mellitus presents a high burden for individuals and society. In Latin America, many people with diabetes have limited access to health care, which means that indirect costs may exceed direct health care cost. Diabetes is Mexico's leading cause of death. PURPOSE: To evaluate the cost-effectiveness ratios of the most used oral hypoglycemic agents (OHA) in the treatment of outpatients with type 2 diabetes attending a public primary care clinic in Mexico City. DESIGN: A cross-sectional and analytic study was conducted in Mexico City. METHODOLOGY: Twenty-seven adult outpatients with type 2 diabetes who were treated either with metformin or glibenclamide were included. Acarbose was used as an alternative strategy. The study was carried out from the perspective of Mexican society. Direct medical and nonmedical costs as well as indirect costs were evaluated using a structured questionnaire. Efficacies of all drug treatments were evaluated retrospectively. A systematic search was conducted to select published randomized clinical trials based on predetermined inclusion criteria, and treatment success was defined as glycosylated hemoglobin factor ≤ 7%. Efficacy data of each drug and/or combination were analyzed using meta-analysis. The Monte Carlo Markov model was used. Quality-adjusted life-years (QALY) were used as the unit of effectiveness; incremental and sensitive analyses were performed and a 5% discount rate was calculated. A hypothetical cohort of 10,000 patients was modeled. RESULTS: The odds ratios of the success of each drug treatment were obtained from the meta-analyses, and were the following: 5.82 (glibenclamide), 3.86 (metformin), 3.5 (acarbose), and 6.76 (metformin-glibenclamide). The cost-effectiveness ratios found were US$272.63/QALY (glibenclamide), US$296.48/QALY (metformin), and US$409.86/QALY (acarbose). Sensitivity analysis did not show changes for the most cost-effective therapy when the effectiveness probabilities or treatment costs were modified. CONCLUSION: Glibenclamide is the most cost-effective treatment for the present study outpatient population diagnosed with type 2 diabetes in the early stages.
