Hospital care direct costs due to ambulatory care sensitive conditions related to diabetes mellitus in the Mexican public healthcare system.

BACKGROUND: Hospitalizations for ambulatory care sensitive conditions (ACSC) incur substantial costs on the health system that could be partially avoided with adequate outpatient care. Complications of chronic diseases, such as diabetes mellitus (DM), are considered ACSC. Previous studies have shown that hospitalizations due to diabetes have a significant financial burden. In Mexico, DM is a major health concern and a leading cause of death, but there is limited evidence available. This study aimed to estimate the direct costs of hospitalizations by DM-related ACSC in the Mexican public health system. METHODS: We selected three hospitals from each of Mexico's main public institutions: the Mexican Social Security Institute (IMSS), the Ministry of Health (MoH), and the Institute of Social Security and Services for State Workers (ISSSTE). We employed a bottom-up microcosting approach from the healthcare provider perspective to estimate the total direct costs of hospitalizations for DM-related ACSC. Input data regarding length of stay (LoS), consultations, medications, colloid/crystalloid solutions, procedures, and laboratory/medical imaging studies were obtained from clinical records of a random sample of 532 hospitalizations out of a total of 1,803 DM-related ACSC (ICD-10 codes) discharges during 2016. RESULTS: The average cost per DM-related ACSC hospitalization varies among institutions, ranging from $1,427 in the MoH to $1,677 in the IMSS and $1,754 in the ISSSTE. The three institutions' largest expenses are LoS and procedures. Peripheral circulatory and renal complications were the major drivers of hospitalization costs for patients with DM-related ACSC. Direct costs due to hospitalizations for DM-related ACSC in these three institutions represent 1% of the gross domestic product (GDP) dedicated to health and social services and 2% of total hospital care expenses. CONCLUSIONS: The direct costs of hospitalizations for DM-related ACSC vary considerably across institutions. Disparities in such costs for the same ACSC among different institutions suggest potential disparities in care quality across primary and hospital settings (processes and resource utilization), which should be further investigated to ensure optimal supply utilization. Prioritizing preventive measures for peripheral circulatory and renal complications in DM patients could be highly beneficial.

Avoidable Hospitalization Trends From Ambulatory Care-Sensitive Conditions in the Public Health System in México.

OBJECTIVES: To estimate and identify the variations in rates of Avoidable Hospitalization for Ambulatory Care Sensitive Conditions (AH-ACSC) in public institutions of the Mexican health system during the period 2010-2017. METHODS: Secondary analysis of the hospital discharge database of the Ministry of Health (MoH) from 2010 to 2017. AH for ACSC was calculated by age group and sex per 100,000. Variations per year between institutions were calculated with the extreme quotient (EQ), coefficient of variation (CV) and systematic component of variance (SCV). Adjusted AH rates were calculated by group of causes (acute, chronic and preventable by vaccination). Adjusted AH trend rates were analyzed by Join Point Regression. RESULTS: For the period 2010-2017, the number of AH for ACSC decreased from 676,705 to 612,897, going from almost 13% to 10.7% of hospital discharges. There is consistency in terms of relative variance magnitude. But, with regards to SCV, the change remained constant, and in a second period of 2015-2017, high variation was observed by SCV ≥ 3. All-cause AH is diminishing in all institutions. AH rates for diabetes are the highest, but like other chronic diseases, there was a decline in the period from 2010 to 2017. The relative reduction varied from 15% for heart failure to 38% for complications from diabetes or hypertension, to 75% for angina. CONCLUSIONS: AH for ACSC is an indirect indicator of quality and access to first-level care. Variations by institutions are observed. This variation in CV and SCV across subsystems and states may be due to inequities in the provision of services. The factors that contribute to the burden of AH for ACSC in the Mexican Health System require detailed analysis.

Barriers and opportunities to improve the foundations for high-quality healthcare in the Mexican Health System.

This study aimed to describe the foundations for quality of care (QoC) in the Mexican public health sector and identify barriers to quality evaluation and improvement from the perspective of the QoC leaders of the main public health sector institutions: Ministry of Health (MoH), the Mexican Institute of Social Security (IMSS) and the Institute of Social Security of State Workers (ISSSTE). We administered a semi-structured online questionnaire that gathered information on foundations (governance, health workforce, platforms, tools and population), evaluation and improvement activities for QoC; 320 leaders from MoH, IMSS and ISSSTE participated. We used thematic content and descriptive analyses to analyse the data. We found that QoC foundations, evaluation and improvement activities pose essential challenges for the Mexican health sector. Governance for QoC is weakly aligned across MoH, IMSS and ISSSTE. Each institution follows its own agenda of evaluation and improvement programmes and has distinct QoC indicators and information systems. The institutions share similar barriers to strengthening QoC: poor organizational structure at a facility level, scarcity of financial resources, lack of training in QoC for executive/managerial staff and health professionals and limited public participation. In conclusion, a stronger legal framework and policy dialogue is needed to foster governance by the MoH, to define and align health sector-wide QoC policies, and to set common goals and articulate QoC improvement actions among institutions. Robust QoC organizational structure with designated staff and clarity on their responsibilities should be established at all levels of healthcare. Investment is necessary to fund formal and in-service QoC training programmes for health professionals and to reinforce quality evaluation and improvement activities and quality information systems. QoC evaluation results should be available to healthcare providers and the population. Active public participation in the design and implementation of improvement initiatives should be strengthened.

[Characterization of stroke patients attended at IMSS hospitals in Mexico City]. / Caracterización de los pacientes con EVC atendidos en hospitales del IMSS en la Ciudad de México.

BACKGROUND: Cerebrovascular disease (CD) is considered a problem of huge social, economic and public health implications worldwide in adults and elderly. In Mexico, the information concerning the provision of services to people and their characteristics is limited. The objective is to describe the characteristics of patients with CV who attended the hospitals of the Instituto Mexicano del Seguro Social (IMSS) in Mexico City. METHODS: It was carried out a cohort study of patients with ischemic or hemorrhagic CD who arrived to IMSS. Patients were recruited from seven IMSS general hospitals in Mexico City from June, 2013, to October, 2014. RESULTS: We assigned 430 subjects with CD (78.14% had ischemic CD). There were no statistical differences regarding gender. The median age of patients was 74 years. During their first 72 hours of hospital stay, it was assessed language proficiency in 90%, the ability to walk in 16.3% and the ability to move extremities in 94%. The main risk factors were hypertension, 84%; diabetes mellitus, 46.3%; history of CD, 25.1%; smoking history, 13.7%. 80% of patients reported that their health was regular or poor. CONCLUSIONS: General characteristics of patients and vascular risk factors are similar to those reported by other studies. Secondary prevention strategies are performed in less time than that recommended by international standards. It is urgent to design strategies to build better ways of care during the acute phase of patients with CD.

INTRODUCCIÓN: la enfermedad vascular cerebral (EVC) es un problema de grandes implicaciones a nivel mundial en población adulta y adultos mayores. Es limitada la información en México sobre la provisión de servicios a población con EVC y sus características. El objetivo es presentar las características de la población con EVC que acude a unidades hospitalarias del Instituto Mexicano del Seguro Social (IMSS) en la Ciudad de México. MÉTODOS: estudio de cohorte en pacientes con EVC isquémica o hemorrágica que llegaron a los servicios de urgencias de hospitales del IMSS. Los pacientes fueron reclutados de siete hospitales generales de zona en la Ciudad de México, de junio del 2013 a octubre del 2014. RESULTADOS: fueron 430 sujetos con EVC (78.14% presentó EVC isquémica). No hubo diferencias estadísticas entre hombres y mujeres. La mediana de edad fue 74 años. Durante las primeras 72 horas de su estancia hospitalaria, en 90% se evaluó la capacidad del lenguaje, en 16.3% la capacidad para caminar y en 94% la capacidad para mover las extremidades. Los factores de riesgo fueron hipertensión arterial (84%), diabetes mellitus (46.3%), antecedentes de EVC (25.1%), antecedentes de tabaquismo (13.7%). El 80% refirió que su salud era regular o mala. CONCLUSIONES: las características generales de los pacientes y los factores de riesgo vascular son similares a los reportados en otros estudios. Las estrategias de prevención secundaria se hacen en menos tiempo que el recomendado por los estándares internacionales. Es importante diseñar estrategias para mejorar la atención en la fase aguda de los pacientes con EVC.

[Experience of the Mexican National Health System in the development of clinical practice guidelines]. / Experiencia del Sistema Nacional de Salud Mexicano en el desarrollo de guías de práctica clínica.

BACKGROUND: Clinical practice guidelines are tools that have been able to streamline decisions made in health issues and to decrease the gap between clinical action and scientific evidence. OBJECTIVE: The objective of the study is to share the experience in the development and to update the guidelines by the National Health System of Mexico. MATERIAL AND METHODS: The methodology in the development of the guidelines consists of 5 phases: prioritisation, establishment of work groups, development by adoption of international guidelines of de novo, validation and integration in the Master catalogue of clinical practice guidelines for its dissemination. RESULTS: The Master catalogue of clinical practice guidelines contains 664 guidelines, distributed in 42% Internal Medicine, 22% Surgery, 24% Pediatrics and 12% Gynecology. From the total of guidelines coverage is granted at an 85% of the Universal catalogue of health services, an 84% of the Catastrophic expenses protection fund and a 61% of the XXI Century Medical Insurance of the National Commission of Social Protection in Health. DISCUSSION: The result is the sum of a great effort of coordination and cooperation between the institutions of the National Health System, political wills and a commitment of 3,477 health professionals that participate in guidelines' development and update. CONCLUSION: Master catalogue guidelines' integration, diffusion and implantation improve quality of attention and security of the users of the National Health System.

Caregiver burden of Mexican dementia patients: the role of dysexecutive syndrome, sleep disorders, schooling and caregiver depression.

AIMS: As a result of the accelerated growth of the elderly population, reconfiguration of families and member roles, and the increase of mental disorders, it is necessary to investigate the effects of this set of factors on the caregivers of patients with dementia in Mexico. Mental disorders of individuals have a negative impact on their physical and emotional quality of life, leading to greater dependence and making the caring experience a heavy burden. Several studies (none in Mexico) have used either the characteristics of the patient or caregiver to determine the burden, but few studies have included both profiles within a single study. The objective of the present study was to analyze the characteristics of the patients and caregivers associated with caregiver burden. METHODS: A multicenter study was carried out in six health institutions located in Mexico City, including 175 patients (and their caregivers) diagnosed with different types of dementia. We used the Spanish Caregiver Burden Screen. Descriptive analysis and logistic regressions were used to estimate the effect of the covariates on the caregiver burden. RESULTS: The results showed that patient variables have a greater impact on caregiver burden than caregiver-associated variables. Dysexecutive syndrome, sleep disorders, schooling and caregiver depression are associated with a higher level of caregiver burden. CONCLUSIONS: Caregiver burden is a complex phenomenon. The results of the present study showed the need to implement multifactorial interventions targeting the caregiver to reduce the burden, strengthen the skills for patient management to avoid depression, improve patient health, and diminish functional dependence and future hospitalization.

[Clinical practice guideline. Traumatic urethral stenosis in males]. / Guía de práctica clínica. La estenosis de uretra postraumática en el hombre.

The incidence of urethral stenosis in Mexico had not been documented. At the Centro Médico Nacional La Raza, during the year 2010, 629 patients with urethral stenosis were attended as outpatient consultation: 85 % with previous urethral stenosis and 15 % with urethral treatment complication. Urethral stenosis is a chronic illness, with multiple etiological origins and the handling is controversial. It has a great negative impact for the patients and the recurrence reaches 85 %. The treatment consisted of an invasive approach (urethral dilations, endoscopy procedure) and open surgery (urethroplasty). The World Health Organization and World Alliance take the world challenge about the urinary tract infections associated with the attention of patients, focused on urethral stenosis. The objective of the following clinical guide is to offer to the health professional a clinical tool for making decisions in the handling of the hardship or masculine urethral stenosis, based on the best available evidence, carrying out in systematized form with bibliographical research using validated terms of the MeSH: urethral structures, in the databases Trip database, PubMed, Guideline Clearinghouse, Cochrane Library and Ovid.

En México no está documentada la incidencia de la estenosis de uretra en forma consistente. En 2010, en el Centro Médico Nacional La Raza se reportaron 629 pacientes en consulta externa, 85 % de uretra anterior y 15 % de uretra posterior. La estenosis uretral es una enfermedad crónica, de etiología variada y manejo controvertido, con gran impacto negativo para los pacientes y recurrencia hasta de 85 %. El tratamiento puede ser instrumentado (dilataciones, cirugía endoscópica) y por cirugía abierta (uretroplastia). La Organización Mundial de la Salud y Alianza Mundial la consideran un reto de la atención de la salud. El objetivo de la siguiente guía es ofrecer al profesional de la salud, una herramienta clínica para la toma de decisiones en la atención de la estenosis uretral masculina, basada en la mejor evidencia identificada mediante la búsqueda bibliográfica sistematizada en las bases de datos Tripdatabase, PubMed, Guideline Clearinghouse, Cochrane Library y Ovid.

[Practice guideline. Diagnosis and treatment of type 2 diabetes mellitus]. / Guía de práctica clínica. Diagnóstico y tratamiento de la diabetes mellitus tipo 2.

Our objective was to develop a guide based on the best available evidence that allow family physicians to establish criteria for screening, diagnosis, prevention, treatment of disease, early detection and management of complications; to standardize the organizing processes of the diabetic patient's care in the primary care level; and to achieve lifestyle modification for patients and promote self-care. Clinical questions were stated according to the diagram and structured patient-intervention-comparison-outcome. We used a mixed methodology-adoption adjustment, and include 32 guides. For recommendations not included in these, the search process was conducted in PubMed and Cochrane Library Plus with these terms: diabetes mellitus type 2, epidemiology, detection and diagnosis, classification, drug therapy, effects, prevention, control and complication. The clinical practice guideline emphasizes the fundamental change in lifestyle (diet and exercise), self-care and proactive participation of the patient, in addition to the dynamic prescription of medications that would achieve metabolic control in order to reduce late complications.

[Perspective on type 2 diabetes mellitus in the Instituto Mexicano del Seguro Social]. / Perspectiva de la diabetes mellitus tipo 2 en el Instituto Mexicano del Seguro Social.

The Instituto Mexicano del Seguro Social--always sensitive to the needs of health of the beneficiary population and to the demographic and epidemiological changes of the society--has developed and implemented DiabetlMSS, a program of attention to the diabetic patient. DiabetlMSS organizes care processes based on the needs and values of the patients, through simultaneous activities of individual consultation and group meetings granted by the multidisciplinary health team. These actions and activities are focused to affect patients' lifestyles positively. Through a plan of nutrition, physical activity, self-care and monitoring, this program increases the interaction between patients, by having an exchange of successful experiences about diabetes control. DiabetlMSS was created with the purpose that the patients achieve the metabolic control and identify complications early on, with the perspective of timely intervention that is reflected in the decrease of the catastrophic effects that causes the disease, both for patient's life expectancy and the quality of care provided by the Institute.

[Clinical practice guideline: a complete geriatric evaluation]. / Guía de práctica clínica. Valoración geriátrica integral.

The care of elderly patients requires an evaluation that deserves a host of special considerations, such as biological aspects of aging, those related to activities of daily living and functionality, neuro-psychological conceptions, family dynamics and economic conditions. The growth of the aging population in our country is accompanied by an increase in chronic diseases and more individuals have greater vulnerability, requiring a more consumption of resources because of the high demand for services. This requires the incorporation of specialized care in the institutional system, which has caused serious consequences in the current health system, benefiting specialization and technology, but with a loss of an integrated and horizontal view of the patient. Therefore it is necessary to develop a practical tool that allows the family physician to identify and differentiate the geriatric population that requires specialized care from who does not, identifying problems that may improve and allow the design of strategies to improve health status and maintain functional autonomy of the elderly. Comprehensive Geriatric Assessment (CGA) is a fundamental tool for clinical practice of any medical care to the elderly.

[Validation of the Quality of Life in Alzheimer's Disease (QOL-AD) scale in Mexican patients with Alzheimer, vascular and mixed-type dementia]. / Validación de la escala Quality of Life in Alzheimer's Disease (QOL-AD) en pacientes mexicanos con demencia tipo Alzheimer, vascular y mixta.

AIM: To adapt the Quality of Life in Alzheimer's Disease (QOL-AD) scale to Spanish, as well as to evaluate its reliability and validity in Mexico. SUBJECTS AND METHODS: The study involved a sample of 114 patients diagnosed with Alzheimer, vascular and mixed-type dementia, according to the criteria of the National Institute for Neurological and Communicative Disorders/Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA), the National Institute of Neurological Disorders and Stroke/Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN) and the Alzheimer's Disease Diagnostic and Treatment Centers (ADDTC), respectively. Their primary caregivers (n = 114) and a control group (n = 30) of persons aged 60 or over without dementia and their closest relatives were also evaluated. RESULTS: The total group with dementia obtained a mean age and a standard deviation of 80.15 +/- 7.13. The Folstein minimental test was 18.55 +/- 4.99. We obtained a Cronbach's alpha of 0.88 for the patient version of the QOL-AD (QOL-ADp) and 0.82 for the caregiver version of the QOL-AD (QOL-ADc). The test-retest yielded an intraclass correlation coefficient of 0.9 (p < 0.001; 95% confidence interval, CI 95% = 0.58-0.91) for the QOL-ADp and 0.81 (p < 0.001; CI 95% = 0.78-0.95) for the QOL-ADc. Moreover, the QOL-ADp showed a significant correlation with the geriatric depression scale (r = -0.73; p < 0.001) and with the neuropsychiatric inventory (r = -0.44; p < 0.001). With the QOL-ADc, these correlations were r = -0.5 (p < 0.001) and r = -0.3 (p < 0.001), respectively. Both versions of the QOL-AD were able to distinguish between the group of subjects with dementia and the control group. CONCLUSIONS: The QOL-AD yielded satisfactory results in terms of internal and external reliability, validity between measurements and between known groups. Thus, we can recommend its use to evaluate the quality of life of patients with dementia.

Effects of two educational programmes aimed at improving the utilization of non-opioid analgesics in family medicine clinics in Mexico.

OBJECTIVES: To develop and test two educational programmes (interactive and passive) aimed at improving family doctors' (FD) prescribing practices and patient's knowledge and use of non-opioid analgesics (NOA). METHODS: The educational programmes were conducted in two family medicine clinics by using a three-stage approach: baseline evaluation, design, and implementation of educational activities, and post-programme evaluation. An interactive educational programme (IEP) was compared with a passive educational programme (PEP); both were participated by FDs and patients. The IEP for FDs comprised of workshops, discussion groups, in-service training and guidelines, while for patients the IEP consisted of an interactive session with a video, leaflets and a discussion. The PEP consisted in delivering the guidelines to the FDs and the leaflets to patients. The effect of the programmes on the FDs was measured through the appropriateness of prescriptions and analysed using the differences-in-differences estimator (D-in-D), and on patients through changes in self-medication and in their knowledge about the proper use and adverse events by analysing the inter- and intra-group differences before and after the programmes. RESULTS: The IEP obtained better results to improve appropriate FDs prescription of NOA than PEP (D-in-D = 15%). Regarding the patients, the PEP group reached higher reduction of self-medication than the IEP group (13.4% vs. 9.1%); the knowledge of proper NOA use increased by 8.5% in both groups, whereas knowledge of NOA-related adverse events was better in the IEP (39.6%) than in the PEP group (9.2%). CONCLUSIONS: The IEP was better to improve the doctors' abilities to prescribe NOAs, and both programmes improved patients' knowledge.

Effectiveness of two rehabilitation strategies provided by nurses for stroke patients in Mexico.

OBJECTIVE: Rehabilitation strategies have been developed to improve functional state in stroke patients. The main objective of this study was to evaluate the effectiveness of the early rehabilitation at hospital and its continuity at home provided by nurses, on the functional recovery of basic and social activities in stroke patients compared with conventional care. DESIGN: A randomised clinical trial was carried out in three general hospitals of the Mexican Institute of Social Security (IMSS) in Mexico City between April 2003-May 2004. PARTICIPANTS: Stroke patients. METHODS: Two rehabilitation strategies provided by nurses for stroke patients were compared: physiotherapy plus caregiver education in rehabilitation (strategy 1, S1) vs. education alone (strategy 2, S2). The main outcome variables were the basic (Barthel index) and social (Frenchay activities index) activities of daily living, of each patient. Age, sex, morbidity, stroke symptoms, complications, neurological damage (Canadian Scale), cognitive state (mini-mental state examination questionnaire) and duration of hospitalisation were defined as the control variables. Patients were evaluated at baseline and months one, three and six thereafter. RESULTS: One hundred and ten patients with ischaemic stroke were enrolled and randomised; 59 were assigned to S1 and 51 to S2. Comparison of the outcome variables showed that patients improved significantly over time, but no differences were observed between groups. We observed no significant difference in strategy performance with regard to the basic and instrumental activities of daily living. RELEVANCE TO CLINICAL PRACTICE: Participants who received physiotherapy with additional caregiver education benefit no more than those whose caregivers received education alone. Those countries that do not have integral rehabilitation programmes for stroke patients should understand their importance and budget resources for them. Meanwhile, both caregiver education and nurses trained in specific care and physiotherapy are alternatives that benefit these patients.

[Health needs in marginalized urban areas in Mexico]. / Necesidades de salud en áreas urbanas marginadas de México.

OBJECTIVE: To understand the health needs of the population living in Mexico's marginalized urban areas. METHODS: A population-based survey of families residing in poor, urban neighborhoods, in five geographic areas in Mexico (northern, central, southern, south-east, and Mexico City), selected through multistage sampling. Interviews were conducted and anthropometric measurements were taken in the home, and included all members of the participating family. Analysis was carried out on positive health factors, nutrition, reproductive health, health problems, and mental health, and results were disaggregated by age and sex. RESULTS: In all, 24,707 individuals participated. The interviewees were found to have minimal schooling (6 years or less). Only 46.8% had health care coverage, be it public or private. Among the children, 19.8% were malnourished; overweight was prevalent from adolescence onwards. Of adolescents 12-19 years of age, 15.7% were sexually active, but only 57.7% of the males and 41.9% of the females in this age group were using some method of contraception. Of the adults, 5.9% suffered from diabetes and 11.5%, from high blood pressure. In the sample of adolescents, adults, and elderly adults, tobacco use was 21.2%; alcohol consumption, 36.0%; illicit drug use, 9.5%; and depression, 20.2%. CONCLUSIONS: The health needs of people living in Mexico's marginalized urban areas proliferate in the context of a young population with weak ties and little support from family and health services. They face crisis and disease--infant malnutrition, high-risk pregnancy, and addictions--the byproducts of disparities in social progress. The rate of chronic conditions was similar to that of the general population of Mexico.

Necesidades de salud en áreas urbanas marginadas de México / Health needs in marginalized urban areas in Mexico

OBJETIVO: Evaluar las necesidades de salud de la población residente en áreas urbanas marginadas de México. MÉTODOS: Encuesta poblacional a familias residentes en colonias urbanas pobres de cinco regiones geográficas de México (Norte, Centro, Sur, Sureste y Ciudad de México), seleccionadas mediante un muestreo polietápico. Se realizaron entrevistas y mediciones antropométricas en sus domicilios a todos los integrantes de las familias seleccionadas y se analizaron las características de salud positiva, nutrición, salud reproductiva, daños a la salud y salud mental por grupos de análisis formados por edad y sexo. RESULTADOS: Participaron 24 707 personas. En los entrevistados se observó una baja escolaridad (6 años o menos) y solo 46,8 por ciento tuvo cobertura de servicios de salud, ya fuera en instituciones públicas o privadas. De los niños, 19,8 por ciento presentaba desmedro y el sobrepeso predominó a partir de la adolescencia. En los adolescentes de 12 a 19 años, 15,7 por ciento tenía vida sexual activa, pero solo 57,7 por ciento de los hombres y 41,9 por ciento de las mujeres de ese grupo de edad usaban algún método anticonceptivo. De los adultos, 5,9 por ciento padecía diabetes y 11,5 por ciento hipertensión arterial. En la muestra de adolescentes, adultos y adultos mayores, el tabaquismo fue de 21,2 por ciento, el consumo de alcohol de 36,0 por ciento, el uso de drogas de 9,5 por ciento y la depresión de 20,2 por ciento. CONCLUSIONES: La vulnerabilidad sanitaria de las personas que viven en las áreas urbanas marginadas de México se manifiesta en la existencia de una población joven, con pocas redes de apoyo familiar y de servicios de salud, que sufre trastornos y enfermedades, como la desnutrición infantil, el alto riesgo reproductivo y las adicciones en adolescentes y adultos, producto del rezago en el desarrollo social. La prevalencia de enfermedades crónicas fue similar a la de la población mexicana no marginada.

[Health risks for adolescents in underserved areas]. / Riesgos para la salud de los adolescentes en áreas marginadas.

Background: adolescent population is an important age group, with vulnerability and health needs not well known, especially for those living in urban slums. Our objective was to identify health risks for adolescents living in poor urban areas in five geographical regions of Mexico. Methods: a secondary data analysis from a nationwide adolescents ́ survey was carried out from population living in poor urban areas of the north, center, DF, south and southeast of Mexico. Cigarette smoking, alcohol and drug consumption, as well as frequency of accidents and violence, age at sexual initiation and use of contraception methods were analyzed. Results: the highest frequencies of consumption were: 27.8 % for cigarette smoking and 35.2 % for alcohol, both in adolescents from 16 to 19 years; accidents (5 %) and violence (1.7 %); age (median) at sexual initiation was 16 years, about 50 % of adolescents with regular sexual activity reported use of a contraception method. Conclusions: comparing our data with National Health Surveys; in poor urban areas, most adolescents health risks are higher than those found for same group age in the general population, however, presentation of accidents and violence are similar.

Introducción: : los adolescentes son un grupo con vulnerabilidad y necesidades de salud poco conocidas en México, principalmente en áreas de pobreza urbana. El objetivo de esta investigación fue identificar los riesgos para la salud de los adolescentes en las áreas urbanas marginadas en cinco regiones del país. Métodos: análisis secundario de una encuesta de salud para adolescentes realizada en áreas urbanas marginadas del Distrito Federal y regiones norte, centro, sur y sureste del país; se analizó consumo de tabaco, alcohol y drogas; historia de accidentes y violencias, edad de inicio de vida sexual y uso de métodos anticonceptivos; se calcularon frecuencias absolutas y relativas. Resultados: los consumos más altos fueron para tabaco (27.8 %) y alcohol (35.2 %), ambos en el grupo de 16 a 19 años de edad; 5 % sufrió algún accidente y 1.7 %, violencia; el inicio de la vida sexual tuvo una mediana de 16 años y 50 % utilizaba algún método anticonceptivo. Conclusiones: al comparar nuestros datos con los de otras encuestas nacionales, se encontró que los riesgos para la salud son mayores en los adolescentes de áreas urbanas marginadas que en adolescentes de la población general, sin embargo, la frecuencia de accidentes y violencias fue similar.

[Guide for appropriate using of the non-opioid analgesics in the management of pain]. / Guía para la utilización de analgésicos no opioides en el manejo del dolor.

The purpose of this guide is to provide for general practitioners or physicians of primary care a comprehensive, evidence based tool that permits them to take an adequate decision about the appropriate use of the non-opioid analgesics in the management of pain.

Conocimiento básico de los riesgos del uso de analgésicos no opioides en pacientes ambulatorios / Basic knowledge of risks for non-opioid analgesics (NOA) in ambulatory patients

OBJETIVO: Evaluar el conocimiento básico de los pacientes acerca de los analgésicos no opioides (ANOP) e identificar los posibles factores relacionados con la falta de información sobre este tipo de analgésicos. MATERIAL Y MÉTODOS: Participaron 629 pacientes >50 años con síndrome doloroso de origen no oncológico y que recibieron ANOP. Se analizaron sus características generales, la información recibida y su conocimiento sobre ANOP. La variable dependiente fue la falta de conocimiento básico (FCB) sobre ANOP. Se realizó análisis descriptivo y bivariado. RESULTADOS: Del total de participantes, 64.2 por ciento tuvo FCB; 28 por ciento desconocía la forma correcta de tomar ANOP y 48 por ciento sabía que ocasionan trastornos gastrointestinales. Factores asociados con la FCB: no recibir información sobre ANOP (RM= 2.22; IC95 por ciento 1.32-3.70), escolaridad < 7 años (RM= 1.87; IC95 por ciento 1.33-2.63) y duración del dolor < 4 años (RM=1.70; IC95 por ciento 1.22-2.37). CONCLUSIONES: Los pacientes carecen de conocimiento y reciben poca información acerca de ANOP. Es indispensable promover acciones para solucionar este problema.

OBJECTIVE: To describe patients’ knowledge of non-opioid analgesics (NOA) and to identify factors associated with patients’ lack of basic knowledge (LBN) on this type of medication. MATERIAL AND METHODS: A total of 629 ambulatory patients older than 50 years of age, with non-malignant pain syndrome, attended to two family medicine clinics and received seven day prescriptions for NOA. The data on patients’ general characteristics, the information they received and their actual knowledge of NOA were analyzed using descriptive statistics and bivariate analysis. RESULTS: A total of 64.2 percent had LBN; 28 percent did not know how to take NOA properly, and 48 percent knew that these drugs cause gastrointestinal adverse effects. The factors significantly associated with LBN on NOA included: failure to receive information on NOA (OR:2.22, 95 percentCI 1.32-3.70), education <7 years (OR:1.87, 95 percentCI 1.33-2.63) and pain duration <4 years (OR:1.70, 95 percentCI 1.22-2.37). CONCLUSION: Patients lack knowledge and receive little information on NOA. It is important to encourage actions to tackle this problem.
