[Detection of embryonic mortality in cattle using sonography].

In 70 pregnant cattle the diameter of conceptus, the size of embryo and corpus luteum were estimated with a 5 MHz-linear array scanner on days 22, 25, 28, 35 and 42 (+/- 1 day) after insemination. Additionally, the milk progesterone level was determined. Embryonic mortality was found in 7 cases, in 3 cows on day 35, in 4 cows on day 42. The lack of embryonic heart beat was the first sign; later in pregnancy significant differences in sizes of conceptus and embryo compared with physiological pregnancies occurred. Membranes and bubble-like structures became visible in the lumen of the conceptus. The conceptus could be detected until the following oestrus, which began 8 to 42 days after embryonic death. The corpus luteum remained until proestrus. This correlated positively with the progesterone levels.

Treatment patterns for schizophrenia in psychiatric hospitals.

This paper analyzes the patterns of clinical treatments prescribed to patients diagnosed with schizophrenia who were admitted to state and county mental hospitals, private for-profit psychiatric hospitals, and private nonprofit psychiatric hospitals in July 1980. Treatment patterns were specified by examining the distribution of treatment types provided to patients over a 3-month period through standard tabular arrays and matrix analysis that holds constant the number of treatment types received by the patients. Data for this study are based on nationwide patient sample surveys and facility enumerations conducted in 1980 by the Survey and Reports Branch, National Institute of Mental Health. Clear differences and similarities emerged among the three types of hospitals in terms of the number and type of treatments provided to patients with schizophrenia. In general, patients with schizophrenia admitted to private psychiatric hospitals received a more comprehensive care regimen (generally inclusive of individual therapy) than similarly diagnosed patients admitted to state and county mental hospitals; private nonprofit psychiatric hospitals had marginally discernible treatment patterns from private for-profit psychiatric hospitals, especially with respect to assignment of group and self-care skill training.

Professional uncertainty and physician medical decision-making in a multiple treatment framework.

This paper develops a new microanalytic approach to physician medical decision-making treatment setting. Physician medical decision-making is modelled as a two-stage sequential process. In Stage 1, the patient's illness is diagnosed and the health outcomes for all illness-related restoration options are identified. In Stage 2, an "optimal" restoration option is selected. This model provides new insights into physician medical decision-making and the complexity of proving physician-induced demand in a medical care market where professional uncertainty and consumer heterogeneity exist.

DRG panic.

The authors describe the successful development and implementation of a multi-use nursing information system. Developed under the direction of nursing administration, this system serves as a database for statistical analysis, utilization review, and budget management. The intent of the article is to encourage nursing administrators with information systems to use them to the fullest possible extent.
