[Perception of the quality of care in the health services in Mexico. perspective of the users]. / Percepción de la calidad de la atención de los servicios de salud en México: perspectiva de los usuarios.

OBJECTIVE: To describe the quality of health services as perceived by users in Mexico, as well as an analysis of predisposing and enabling factors to the use of these services. MATERIAL AND METHODS: Data were selected from the National Health Survey II of 1994. The survey contains information from 3324 ambulatory health service users who sought care in the two week period previous to the survey. RESULTS: 81.2% of users perceived the quality as good and 18.8% thought it was poor. The main reasons for good quality of care were: personal attention (23.3%) improvement of the health problem (11.9%). For poor quality of care, the main reasons were: long waiting time (23.7%) and poor clinical examination (11.7%) Social security health service users perceived 2.6 times more frequently quality of attention as poor, than those who consulted private health services. Quality is represented by the aspects of the attention process (44.8% 9, its results (21.3%), the structure (18.0%) and accessibility (15.7%) The main reasons for not returning to the same health service center were: deficient attention (18.2%) and long waiting times (11.8%). CONCLUSIONS: The perspective of the population should be studied further and actions for the continuous improvement of the quality of health care should be implemented.

Factors associated with Mexican women's familiarity with the purpose of the Pap test.

Use of health services is usually associated with a variety of factors, including the socioeconomic characteristics of the users, their familiarity with the usefulness of the services provided, and the acceptability and accessibility of those services. To study the factors associated with women's familiarity with the Pap test, a population-based study was carried out in Mexico City and two rural areas in the state of Oaxaca by means of household interviews. The sample consisted of 4208 women 15 to 49 years of age. Univariate, bivariate, and multivariate analyses were done using unconditional logistic regression; the independent variables were access to social security health services, age, education, housing quality, and place of residence (urban or rural); the dependent variable was the interview subject's familiarity with the purpose of the Pap test. The results were expressed as odds ratios with 95% confidence intervals. It was found that 41.5% of the women surveyed did not know the purpose of the Pap test, and that within this latter group, 97% had never had one. Factors found to be associated with not knowing the test's purpose were lack of access to the social security health services (OR = 1.9; 95% CI: 1.5-2.3); illiteracy (OR = 36.1; 95% CI: 17.9-72.7); and low socioeconomic level (OR = 2.9; 95% CI: 2.3-3.7). Also, rural dwellers had less familiarity with the Pap test than urban dwellers (OR = 0.5; 95% CI: 0.4-0.7). These results highlight the need to develop strategies for making the benefits of the Pap test known, bearing in mind the socioeconomic and cultural diversity of the populations involved.

[The coverage of health institutions in the state of Mexico. A comparative analysis of the insured and uninsured populations]. / Cobertura de las instituciones de salud en el Estado de México. Análisis comparativo entre la población asegurada y la no asegurada.

In this paper we report on a survey aimed at comparing utilization patterns and institutional coverage of health services between insured and non-insured populations. Our results show that under fixed socioeconomic characteristics, and for the same health problems, the non-insured group had a utilization rate 1.5 times smaller than that corresponding to the insured. Institutional coverage also showed important variations: only 31.8% of the group potentially served by the Secretary of Health (non-insured group) had actually demanded care, while the corresponding figure for the insured group (those with right to use the services provided by the diverse social security institutions) was 57.6%. On the other hand, private services utilization was 1.7 times higher for the non-insured population. These results point to the need for alternative and more equitable health care models in Mexico.

[Coverage of 4 health programs for pre-school children in marginal urban areas in Mexico City]. / Cobertura de 4 programas de salud para pre-escolares en áreas urbanas marginales de la ciudad de México.

The aim this paper was to evaluate the coverage provided by four preschool child health programs (vaccinations, oral hydration therapy, healthy child care and sick child care). To make coverage operational, we designed indicators to compare the utilization of each program with the condition or health problems considered as needed. These results are part of a broad evaluative research called "Coverage and Quality of Primary Health Care" (CQPHC) carried out by the National Institute of Public Health (NIPH) in the State of Mexico in 1988. The population under study was a random sample of the total of preschool children detected in the household survey. We only analyzed data including children from 1-4 years to ensure that all studied children had completed the basic vaccination schemes. For the vaccination program, we observed a coverage of 47.7%, twice as much as that of the oral hydration program that only reached was 21.9%, whereas that of the sick child care program was 63.8%, the former being 2.0 times less than the latter. We can conclude that the different coverage found for each program is basically due to the lack socialization of the concept of need and to the extent of participation of the concept to make these services available to the population.

Test of a noninvasive instrument for measuring hemoglobin concentration.

A colorimetric instrument for the noninvasive quantification of hemoglobin, designed using color shades resembling those observed in the conjunctiva, was tested. The instrument's colors are contrasted against the color of the conjunctiva to measure hemoglobin content. Sensitivity, specificity, negative predictive value, and false-negative value were estimated to test the instrument's accuracy; kappa coefficients were used to estimate inter- and intraobserver variability. Physician field evaluations of conjunctiva color for the screening of anemia, reported in the literature, have had sensitivities and specificities as high as 70%. Readings with the instrument demonstrated a 63% sensitivity, 72% specificity, and 38% false negatives for screening hemoglobin values of less than or equal to 13 g/dl. The interobserver kappa coefficients for three pairs of readers were good to excellent for the same hemoglobin screening value. Statistically significant differences were noted, however, between observers during the reliability test. The instrument can be used by unskilled personnel to improve their decision-making about whom to send for further care or for supplementation with iron.
