Assessments of managed care organizations in the Greater Baton Rouge area by physicians and physicians' office managers.

Health care quality assessment under managed care organizations is usually derived from two sources: (1) consumer satisfaction surveys, and (2) The Health Plan Employer Data Information Set reports. There is little published data regarding physicians' critiques. This study surveyed physicians and office managers as to the quality of healthcare under 10 managed care organizations in the Greater Baton Rouge area. Performance indicators in the physician questionnaire focused on personal satisfaction, perception of patient satisfaction, and mental health coverage. The office managers' checklist included payment and certification issues, telephone time spent gaining certification, level of knowledge among plan enrollees of their benefits, appeal process, and adequacy of reimbursement. Means were calculated for each performance indicator and managed care organizations were ranked. Tukey-Kramer's post-hoc multiple comparisons test was used to confirm rank order validity. Significant differences were found among companies. Significant rank-order agreement by both physicians and office managers was evident. The usefulness of such surveys and performing them annually is discussed.

World food trends and prospects to 2025.

This paper reviews food (especially cereal) production trends and prospects for the world and its main regions. Despite fears to the contrary, in recent years we have seen continued progress toward better methods of feeding humanity. Sub-Saharan Africa is the sole major exception. Looking to the future, this paper argues that the continuation of recent cereal yield trends should be sufficient to cope with most of the demographically driven expansion of cereal demand that will occur until the year 2025. However, because of an increasing degree of mismatch between the expansion of regional demand and the potential for supply, there will be a major expansion of world cereal (and noncereal food) trade. Other consequences for global agriculture arising from demographic growth include the need to use water much more efficiently and an even greater dependence on nitrogen fertilizers (e.g., South Asia). Farming everywhere will depend more on information-intensive agricultural management procedures. Moreover, despite continued general progress, there still will be a significant number of undernourished people in 2025. Signs of heightened harvest variability, especially in North America, are of serious concern. Thus, although future general food trends are likely to be positive, in some respects we also could be entering a more volatile world.

Infant, child and maternal mortality and associated conditions of health in the Greater Kabul region of Afghanistan.

This acticle presents an analysis of data obtained by the ad hoc Survey of Infant and Early Childhood Mortality in Relation to fertility Patterns, that was conducted in the Greater Kabul region of Afghanistan between 1972 and 1975(2). It begins with an outline of the survey's methodology and some general background information on the population under study. We then derive estimates of fertility and infant and child mortality. This is followed by an examination of the reproductive health of women. We then outline the findings of an intensive enquiry into the correlates and causes of the child deaths observed by the survey. The level of child care of the population is examined with reference to patterns of feeding and immunizaiton. Finally we draw together and comment upon the main findings of the survey.

A population study in the Maldive islands.

The Maldive Islands harbour, among 2,000 widely scattered coral islands, 190 atolls at present inhabited by over 128,000 persons. Between 1956-1976 the Royal Air Force occupied an air staging station which resulted in an increase in material and health prosperity, mostly affecting Hittadu Island. The growth rate which was 2.6% for the Maldivian population prior to that period, increased to 4.4%, resulting in a population density of 1,085 per sqkm. The unenviable prospects of the withdrawal are described.

Levels, trends, differentials and causes of child mortality-a survey.

This paper attempts to give an overview of current levels of child mortality prevailing in the world. It also examines trends and socioeconomic differentials in child mortality for selected countries and regions of the world. Lastly it reviews data on causes of child death and related environmental factors. The paper concludes that despite the fact that child deaths are frequently avoidable, mortality differentials between the developed and developing regions of the world are more pronounced in childhood (ages one to under five years) than at any other time of life. While some developing countries have substantially reduced the level of mortality in childhood, in others it remains very high. In contrast, in most developed countries child death rates are now so low, that they no longer serve as useful measures of public health.
