Cumulative pregnancy and live birth rates after gamete intra-Fallopian transfer.

To evaluate the efficacy of gamete intra-Fallopian transfer (GIFT) the Kaplan-Meier life table method was used to analyse a patient cohort treated with GIFT between 1991 and 1994. In a tertiary referral centre for reproductive medicine, 1628 women with a median age of 33 years and various causes of infertility were included to calculate cumulative pregnancy and live birth rates. Age and cause of infertility were main factor variables and the study was based on a total of 2941 consecutive GIFT cycles, leading to a first clinical pregnancy, and 3052 cycles, leading to a first live birth. The cumulative pregnancy and live birth rates were 49.6 and 38.8% respectively, after three initiated cycles and 64.1 and 52.0% respectively, after five initiated cycles. The multiple pregnancy rate was 22.6%. The implantation rate of 13.1% after GIFT demonstrates that the developing embryo benefits from a period of exposure within the environment of the Fallopian tube. The present results indicate that approximately 50% of couples will have at least one live baby after five initiated GIFT cycles. Advancing age was a major negative prognostic factor for the cumulative live birth rate because of higher cancellation rates, lower implantation rates and higher pregnancy failure rates.

Comparison of two schema for classifying nursing research.

To examine trends in nursing research during the last five years of the 1980s and to test the reliability and validity of two taxonomic schemes to classify nursing research, 811 abstracts from three years of a national nursing research conference (Council of Nurse Researchers, 1983, 87, 89) were reviewed and classified independently by three investigators. Taxonomies were research topics as categorized in the Sigma Theta Tau International Directory of Nurse Researchers (STT) and the Classification of Nursing-Related Dissertations (DISSER). More than half of abstracts addressed clinical topics, and clinical research topics increased significantly over time (p less than .001). At least two of the three raters agreed on coding for 62.8 percent of abstracts with STT schemes, 70.9 percent with DISSER scheme (p less than .01). Additional testing and standardization of taxonomies for nursing research is needed to improve reliability and validity.

A model for predicting utilization of psychiatric facilities.

This paper develops a parsimonious model for predicting utilization of a regional system of psychiatric facilities based on census data. The model combines conceptual simplicity with readily-available data sources. In practical terms, the model removes the need to undertake comprehensive and expensive utilization surveys. In theoretical terms, the model indicates that the fundamental relationship between utilization rates and key social indicators is stable through time. Although further testing is necessary, it would seem that these key indicators can provide reasonable estimates of psychiatric morbidity for up to ten years in the future.

Impact of mental health facilities on property values.

Community opposition to the establishment of a small-scale mental health facility is often intense. One frequently voiced fear is that the estabishment of a facility will cause property values in its vicinity to decline. This paper examines empirical evidence of the impact on property values in the neighborhood of 12 mental health centers in Philadelphia. It is concluded that such facilities have an indeterminate effect on property values in their vicinity, contary to popular opinion.
