The New Mexico experiment: educational innovation and institutional change.

Over the past ten years the University of New Mexico School of Medicine has conducted an educational experiment featuring learner-centered, problem-based, community-oriented learning. The experiment was introduced into an established institution by means of an innovative educational track running parallel to the more conventional curriculum. Students in the innovative track, compared with those in the conventional tract, tended to score lower on the National Board of Medical Examiners (NBME) Part I examination (basic sciences) and higher on NBME Part II (clinical sciences), received higher clinical grades on clinical clerkships, and experienced less distress. They were more likely than conventional-track students to retain their initial interest in or switch their preference to careers in family medicine. The parallel-track strategy for introducing curriculum reform succeeded in fostering institutional acceptance of continuing educational innovation. Generic steps in overcoming institutional barriers to change are identified.

Choice of cancer therapy varies with age of patient.

We used data on 22,899 cancer cases collected by the New Mexico Tumor Registry to examine the relationship between patient age and the use of potentially curative therapy for cancers of selected sites and acute leukemias. For cancers of most sites, either local or regional stage, the proportion of cases receiving potentially curative therapy declined with age. For local-stage cancers, the proportion not given any treatment increased with age. Overall mortality rates during the first year after diagnosis were much higher for local-stage cases without treatment than for those who received treatment. These data show that cancer therapy varies with age and suggest that decision making regarding therapy is influenced by the presence of other diseases.

Health effects of air pollution due to coal combustion in the Chestnut Ridge region of Pennsylvania: cross-section survey of children.

A cross-sectional study of 4,071 children aged 6-11 yr of age from a rural region of Western Pennsylvania was conducted in spring of 1979. Standardized children's questionnaires were distributed to the parents and returned by the children to school, where spirometry was performed. The region was divided into low-, moderate-, and high-pollution areas on the basis of the 1974-1978, 3-hr, 24-hr, and annual averages for sulfur dioxide (SO2). Seventeen monitoring stations in the region and a triangulation procedure were used to estimate centroid levels in each geographic residence area. After adjusting the respiratory symptom response outcomes and the pulmonary function levels for known predictors, no significant association was noted for level of SO2. However, the highest exposure categories were only slightly above the present annual and 24-hr National Air Quality Standards for SO2. We conclude that at levels of exposure to which these children were exposed, only by study of potentially sensitive subsets or measures of acute response would it be possible to detect respiratory outcomes associated with ambient air pollution.
