Measuring the adequacy of antenatal health care: a national cross-sectional study in Mexico

Objective: To propose an antenatal care classification for measuring the continuum of health care based on the concept of adequacy: timeliness of entry into antenatal care, number of antenatal care visits and key processes of care. Methods: In a cross-sectional, retrospective study we used data from the Mexican National Health and Nutrition Survey (ENSANUT) in 2012. This contained self-reported information about antenatal care use by 6494 women during their last pregnancy ending in live birth. Antenatal care was considered to be adequate if a woman attended her first visit during the first trimester of pregnancy, made a minimum of four antenatal care visits and underwent at least seven of the eight recommended procedures during visits. We used multivariate ordinal logistic regression to identify correlates of adequate antenatal care and predicted coverage. Findings: Based on a population-weighted sample of 9 052 044, 98.4% of women received antenatal care during their last pregnancy, but only 71.5% (95% confidence interval, CI: 69.7 to 73.2) received maternal health care classified as adequate. Significant geographic differences in coverage of care were identified among states. The probability of receiving adequate antenatal care was higher among women of higher socioeconomic status, with more years of schooling and with health insurance. Conclusion: While basic antenatal care coverage is high in Mexico, adequate care remains low. Efforts by health systems, governments and researchers to measure and improve antenatal care should adopt a more rigorous definition of care to include important elements of quality such as continuity and processes of care

Search for the standard model Higgs boson in the H to ZZ to 2l 2nu channel in pp collisions at sqrt(s) = 7 TeV

A search for the standard model Higgs boson in the H to ZZ to 2l 2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.Comment: Submitted to JHE

Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV

The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 inverse picobarns of data collected in pp collisions at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum pT larger than a few GeV is above 95% over the whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4, while the probability to misidentify a hadron as a muon is well below 1%. The efficiency to trigger on single muons with pT above a few GeV is higher than 90% over the full eta range, and typically substantially better. The overall momentum scale is measured to a precision of 0.2% with muons from Z decays. The transverse momentum resolution varies from 1% to 6% depending on pseudorapidity for muons with pT below 100 GeV and, using cosmic rays, it is shown to be better than 10% in the central region up to pT = 1 TeV. Observed distributions of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO

Atención prenatal en grupo: efectividad y retos de su implementación

Group prenatal care is an alternative model of care during pregnancy, replacing standard individual prenatal care. The model has shown maternal benefits and has been implemented in different contexts. We conducted a narrative review of the literature in relation to its effectiveness, using databases such as PubMed, EBSCO, Science Direct, Wiley Online and Springer for the period 2002 to 2018. In addition, we discussed the challenges and solutions of its implementation based on our experience in Mexico. Group prenatal care may improve prenatal knowledge and use of family planning services in the postpartum period. The model has been implemented in more than 22 countries and there are challenges to its implementation related to both supply and demand. Supply-side challenges include staff, material resources and organizational issues; demand-side challenges include recruitment and retention of participants, adaptation of material, and perceived privacy. We highlight specific solutions that can be applied in diverse health systems.La atención prenatal en grupo es un modelo alternativo de atención durante el embarazo, que sustituye la atención prenatal individual estándar.

Análisis de costo-efectividad de intervenciones para incrementar la actividad física en hipertensos

   Objective: To perform a cost-effectiveness analysis (CEA) of two programs designed to increase the physical activity (PA) of hypertensive patients at the primary-care level: the first based on the Reference Scheme (RS) and the second on the Brief Counseling (BC) approach, both within the context of a Mexican social security institution: The Mexican Social Security Institute (IMSS). Material and Methods: A CEA was undertaken from the perspective of service providers, with a time horizon of 24 weeks. Effectiveness was estimated in two ways: an increase in the minutes of moderate-vigorous PA (MVPA) and the percentage of patients engaging in ≥150 weekly minutes of MVPA at the end of each program. Results: RS patients performed 8.1 additional minutes of PA (week 24 = 169.29 minutes; week zero = 161.23). RS program proved approximately 1% more expensive and more effective and had an incremental cost-effectiveness ratio of 299 US$ per increased percentage point of patients engaging in ≥150 weekly minutes of MVPA at the end of each program. The sensitivity analysis yielded an up to 56% probability that the RS program would be cost-effective in increasing the percentage of patients performing the targeted MVPA per week. Conclusions: Our results indicate that in the context of a social security institution such as the IMSS, it is not cost-effective to implement an RS-based program to increase physical activity levels in hypertensive patients. Further evidence is required on the cost-effectiveness of both programs regarding other effectiveness measures such as biochemical and physical condition parameters, as well as to other types of population, given that this was the first CEA of PA programs in Mexico. Keywords: Physical activity; Arterial pressure; Cost and cost analysis; Adults.   Objetivo: Realizar un análisis de costo-efectividad (ACE) de dos programas diseñados para incrementar la actividad física (AF) de pacientes hipertensos: el primero basado en el Esquema de Referencia (ER) y el segundo con un enfoque de Asesoramiento o Consejería Breve (CB), ambos en el contexto de primer nivel de atención en una institución de seguridad social de México: El Instituto Mexicano del Seguro Social (IMSS). Material y métodos: Se realizó un ACE desde la perspectiva de los proveedores de servicios, con un horizonte temporal de 24 semanas. La efectividad se midió con dos indicadores: aumento en los minutos de AF moderada-vigorosa (AFMV) y en el porcentaje de pacientes que participaron en ≥150 minutos de AFMV semanales al final de cada programa. Resultados: Los pacientes con ER realizaron 8.1 minutos adicionales de AF (semana 24 = 169.29 minutos; semana cero = 161.23). El programa ER demostró ser aproximadamente 1% más costoso y efectivo, y tuvo una relación costo-efectividad incremental de 299 dólares por cada punto porcentual de incremento de pacientes que cumplían con ≥150 minutos de MVPA semanales al final de cada programa. El análisis de sensibilidad arrojó una probabilidad de hasta 56% de que el programa ER fuera costo-efectivo para aumentar el porcentaje de pacientes que cumplen con las recomendaciones de AF semanales. Conclusiones: Nuestros resultados indican que en el contexto de una institución de seguridad social como el IMSS, no es costo-efectivo implementar un programa basado en ER para aumentar los niveles de actividad física en pacientes hipertensos.Se requiere mayor evidencia sobre la relación costo-efectividad de ambos programas con respecto a otras medidas de efectividad como parámetros bioquímicos y de condición física, así como a otro tipo de población, dado que este fue el primer ACE de programas de AF en México.

Servicios Amigables para Adolescentes: evaluación de la calidad con usuarios simulados

OBJETIVO: Evaluar la calidad de los servicios de salud amigables para adolescentes. MÉTODOS: Evaluación cualitativa utilizando la técnica de usuario simulado en clínicas de primer nivel de los Servicios de Salud de Morelos, México durante 2018. Se seleccionaron aleatoriamente 10 de 17 establecimientos con servicios amigables no exclusivos para adolescentes. Se incluyó adicionalmente un centro con servicios amigables exclusivo para adolescentes como submuestra de tipo intensivo. Cuatro adolescentes fungieron como usuarios simulados interpretando diferentes casos de consulta en las clínicas. Se realizaron 43 entrevistas semiestructuradas de salida y se hicieron dos grupos nominales para evaluar la calidad percibida a partir de la percepción de amigabilidad y la experiencia de los adolescentes. Se realizó análisis temático de los datos obtenidos. RESULTADOS: La actitud del personal destacó como un elemento clave para la experiencia de los adolescentes. Se encontraron fallas como la existencia de barreras burocráticas para el acceso, falta de señalamientos en las clínicas, falta de privacidad y confidencialidad, fallas en la exploración física durante la consulta y falta de seguimiento de los motivos de consulta. La clínica exclusiva para adolescentes ofreció servicios amigables más adecuados en comparación con las clínicas no exclusivas. CONCLUSIÓN: Aunque en la mayoría de los establecimientos visitados el servicio es accesible, aun distan de cumplir con las características de amigabilidad de acuerdo con las recomendaciones internacionales. La clínica exclusiva para adolescentes destacó al contar con mecanismos mejor estructurados que pueden ser implementados en clínicas no exclusivas para mejorar el proceso de atención.OBJECTIVE: To assess the quality of adolescent friendly health services. METHODS: Qualitative assessment using the simulated user technique in first level clinics of Health Services of Morelos, Mexico, during 2018. Ten out of 17 facilities with non-exclusive adolescent friendly services were randomly selected. An additional facility with exclusive adolescent friendly services was included as an intensive subsample. Four adolescents served as simulated users interpreting different cases in the clinics. The total of 43 semi-structured exit interviews were conducted, and two nominal groups were made to assess the perceived quality from the adolescents’ perception of friendliness and experience. Thematic analysis of the data obtained was performed. RESULTS: Staff attitude was highlighted as a key element in the adolescents’ experience. Failures were found, such as the existence of bureaucratic barriers to access, lack of signage in clinics, lack of privacy and confidentiality, failure of physical examination during the appointment and lack of monitoring of the reasons for appointment. The exclusive clinic for adolescents offered more appropriate friendly services compared with nonexclusive clinics. CONCLUSION: Although the service is accessible in most of the clinics visited, it is still far from being friendly according to international recommendations. The exclusive clinic for adolescents stood out for having better structured mechanisms that can be implemented in nonexclusive clinics to improve the care process

Group Prenatal Care in Mexico: perspectives and experiences of health personnel

OBJETIVO: Identificar barreras y facilitadores de la implementación del modelo de Atención Prenatal en Grupo en México (APG), desde la perspectiva del personal de salud. MÉTODOS: Estudio cualitativo descriptivo en cuatro clínicas de la Secretaría de Salud en dos estados de México (Morelos e Hidalgo) de junio de 2016 a agosto de 2018. Se realizaron 11 entrevistas semi-estructuradas a prestadores de servicios de salud. Se exploraron sus percepciones y experiencias durante la implementación del modelo de APG. Se identificaron barreras y facilitadores para su adopción en dos dimensiones: a) estructurales (espacio, recursos, personal de salud, volumen de pacientes, comunidad) y b) actitudinales (motivación, liderazgo, aceptabilidad, abordaje de problemas, clima y comunicación). RESULTADOS: Las barreras más relevantes reportadas en el nivel estructural fueron la disponibilidad de espacio físico en las unidades y la sobrecarga de trabajo del personal de salud. Se identificó la dificultad para adoptar una relación menos jerárquica durante la atención a las gestantes en el nivel actitudinal. El principal facilitador a nivel actitudinal fue la aceptabilidad que los prestadores tienen del modelo. Un hallazgo específico para el contexto de la implementación en México fue la resistencia al cambio en la relación médico-paciente; resulta difícil abandonar el modelo jerárquico prevaleciente y cambiar a una relación más horizontal con las gestantes. CONCLUSIONES: El análisis de la implementación del modelo de APG en México, desde la perspectiva del personal de salud, ha evidenciado barreras y facilitadores similares a las experiencias en otros contextos. Esfuerzos futuros para la adopción del modelo deberán enfocarse en la atención oportuna de las barreras identificadas, sobre todo aquellas señaladas en la dimensión actitudinal que pueden ser modificadas a través de capacitaciones continuas al personal de salud.OBJECTIVE: Identify barriers and facilitators to implementing the Group Prenatal Care model in Mexico (GPC) from the health care personnel’s perspective. METHODS: We carried out a qualitative descriptive study in four clinics of the Ministry of Health in two states of Mexico (Morelos and Hidalgo) from June 2016 to August 2018. We conducted 11 semi-structured interviews with health care service providers, and we examined their perceptions and experiences during the implementation of the GPC model. We identified the barriers and facilitators for its adoption in two dimensions: a) structural (space, resources, health personnel, patient volume, community) and b) attitudinal (motivation, leadership, acceptability, address problems, work atmosphere and communication). RESULTS: The most relevant barriers reported at the structural level were the availability of physical space in health units and the work overload of health personnel. We identified the difficulty in adopting a less hierarchical relationship during the pregnant women’s care at the attitudinal level. The main facilitator at the attitudinal level was the acceptability that providers had of the model. One specific finding for Mexico’s implementation context was the resistance to change the doctor-patient relationship; it is difficult to abandon the prevailing hierarchical model and change to a more horizontal relationship with pregnant women. CONCLUSION: Analyzing the GPC model’s implementation in Mexico, from the health care personnel’s perspective, has revealed barriers and facilitators similar to the experiences in other contexts. Future efforts to adopt the model should focus on timely attention to identified barriers, especially those identified in the attitudinal dimension that can be modified by regular health care personnel training
