ABSTRACT Objetivo. Conocer el nivel de disponibilidad de algunos medicamentos esenciales (ME) en las unidades de primer nivel de atención de la Secretaría de Salud de México (SSA), a partir de una investigación realizada en 1996-1997. Material y métodos. Del universo de jurisdicciones sanitarias de los 18 estados participantes en el Programa de Ampliación de Cobertura (PAC) se construyó una muestra de manera aleatoria. Todas las unidades de primer nivel de atención ubicadas en las jurisdicciones seleccionadas fueron evaluadas mediante una inspección que utilizó una guía que contenía una lista de 36 ME. En una primera fase del análisis se calcularon el número absoluto y la proporción de unidades que no contaban con un solo ejemplar de alguno de los ME de la lista. En las unidades con disponibilidad de medicamentos se calculó la mediana de la distribución. En una segunda fase se realizó la sumatoria por separado de los 36 medicamentos y de los 10 insumos, y se obtuvieron las medias diferenciadas por tipo de centro de salud y por estado. El estadístico utilizado para la comparación de las medias fue la prueba de Scheffé mediante el análisis de varianza de una vía. Posteriormente se agruparon los medicamentos de acuerdo con sus principales tipos de indicación, y se calcularon las medias y las proporciones de medicamentos disponibles. Las diferencias de proporciones se evaluaron con el estadístico ji cuadrada. Resultados. En el momento de la inspección, las unidades visitadas contaban en promedio, con sólo 18 de los 36 medicamentos incluidos en el estudio. Los problemas de abastecimiento de antibióticos, antifímicos y antipalúdicos fueron particularmente graves. En contraste, el abasto de sales de rehidratación oral, métodos de planificación familiar y biológicos fue relativamente aceptable. En general, los estados clasificados como PAC3 presentaron las mejores cifras de abastecimiento. Conclusiones. La SSA de México, en general, y el Programa de Ampliación de Cobertura, en particular, deberán redoblar esfuerzos para acabar con los cuellos de botella que impiden un abastecimiento adecuado de medicamentos esenciales en las unidades de primer nivel de atención. De otra manera, todas las demás actividades dirigidas a atender las necesidades de salud de las poblaciones más marginadas del país resultarán inútiles, ya que el acceso a los medicamentos constituye la pieza final indispensable de la enorme cadena de la atención a la salud.

    ABSTRACT: OBJECTIVE: To analyse the medicines prescription, prescription filling, payment expenditure for medicines by ambulatory health service users (HSU) in 2006, and to evaluate its evolution in the last 12 years. MATERIAL AND METHODS: Using data from the National Health Surveys in 2006 three binary logistic regression models were constructed to identify the variables associated with the prescription rate, prescription filling and payment for medicines in 2006. The results of access to medicines were compared to the ones from previous National Health Services from 1994 and 2000. RESULTS: The type of health service provider was found to be the most important predictors of access to medicines. Although the proportion of HSU obtaining a prescription and paying for drugs has broadly stayed the same as in 1994, the percentage of HSU paying for their prescribed medicines decreased from 70% in 1994 to 42% at Ministry of Health institutions in 2006. CONCLUSION: The progress in prescription and population access to medicines has been uneven across health service providers.

    ABSTRACT: OBJECTIVE: Measure and compare the percentage of prescriptions fully dispensed to persons with and without Popular Health Insurance (SPS in Spanish) who use ambulatory and general hospital services associated with the Mexico State Health Services (SESA in Spanish), and taking into account insurance status. SESA user satisfaction was also measured with respect to access to medication. MATERIAL AND METHODS: Information for the study was taken from four surveys of SESA ambulatory and hospital units that included probabilistic samples with state representativity. Samples of ambulatory units were selected by stratification according to level of care and association to the SPS service network. RESULTS: The findings indicate that the percentage of prescriptions fully dispensed in SESA ambulatory units has improved, reaching approximately 90%, especially among those units offering services to persons affiliated with SPS. Nevertheless, these percentages continue to be lower than those of ambulatory units associated with social security institutions. Percentages of prescriptions fully dispensed have also improved in SESA hospital units, but continue to be relatively low. In nearly all states, as the percentage of prescriptions fully dispensed has increased, user satisfaction with access to medication has also improved. CONCLUSIONS: In 2006 more than 50% of the states had high levels of fully dispensed prescriptions among persons with SPS (>90%). The more significant problem exists among hospitals, since only 44% of users who received a prescription in SESA hospitals in 2006 had their prescriptions fully dispensed. This finding requires a review of SPS medication policies, which have favored highly prescribed low-cost medications at ambulatory services at the expense of higher cost and more therapeutically effective medications for hospital care, the latter having a greater impact on household budgets.

    ABSTRACT: BACKGROUND: Mexico has been experiencing some of the most rapid shifts ever recorded in dietary and physical activity patterns leading to obesity. Diabetes mellitus has played a crucial role causing nearly 14% of all deaths. We wanted to make a comprehensive study of the role of diabetes in terms of burden of disease, prevalence, cost of diabetes, cost of complications and health policy. METHOD: In this paper we review the quantitative data that provides evidence of the extent to which the Mexican health economy is affected by the disease and its complications. We then discuss the current situation of diabetes in Mexico with experts in the field. RESULTS: There was a significant increase in the prevalence of diabetes from 1994 to 2006 with rising direct costs (2006: outpatient USD$ 717,764,787, inpatient USD$ 223,581,099) and indirect costs (2005: USD$ 177,220,390), and rising costs of complications (2010: Retinopathy USD$ 10,323,421; Cardiovascular disease USD$ 12,843,134; Nephropathy USD$ 81,814,501; Neuropathy USD$ 2,760,271; Peripheral vascular disease USD$ 2,042,601). The health policy focused on screening and the creation of self-support groups across the country. CONCLUSIONS: The increasing diabetes mortality and lack of control among diagnosed patients make quality of treatment a major concern in Mexico. The growing prevalence of childhood and adult obesity and the metabolic syndrome suggest that the situation could be even worse in the coming years. The government has reacted strongly with national actions to address the growing burden posed by diabetes. However our research suggests that the prevalence and mortality of diabetes will continue to rise in the future.
