An interactive computer program for studying fetal electroencephalograms.

Fetal electroencephalogram (FEEG), recorded during labor, produces very large volumes of data for visual interpretation. An established terminology, developed for the interpretation of neonatal electroencephalogram, has been found to be useful for visual pattern recognition of FEEG. A program, which identifies FEEG patterns within ten second epochs and provides direct comparison between visual and programmed analysis, has been developed using an interactive computer system. This program provides 85-90 percent consistency with visual interpretation.

Survey of maternal-fetal medicine subspecialists: professional activities, job setting, satisfaction, and trends over time.

The purpose of this survey was to describe the job setting, professional activities, and satisfaction of maternal-fetal medicine (MFM) subspecialists and to compare these with previous surveys. A questionnaire was mailed to members of the Society of Perinatal Obstetricians (SPO). The results were compared to a similar survey in 1986. Of 1,352 members, 58% responded. In comparison to 1986, there was an increase in percentage of women (25%); a decrease in university hospital-based faculty (55%); and an increase in community hospital-based salaried physicians (23%) and private practice (15%). The distribution of professional time changes with an increase in clinical care, a decrease in teaching and research. The annual number of procedures increased for ultrasound and genetics and decreased for gynecologic procedures. Since 1986, there have been significant changes among MFM subspecialists in job setting, allocation of professional time, and number and types of procedures. Job satisfaction remains high.

Approaching the millennium: perinatal problems and software solutions.

Strategic planning for rational development of perinatal computing capabilities for the year 2000 should be driven by anticipated trends in (1) the health care business, (2) computer technology and (3) medicine, as well as (4) the needs of perinatal practitioners. In the USA, health care is the fastest growing segment of the economy. This will produce increasing attention from hardware and software developers, and vendors, and will lead to a proliferation of computing platforms, operating systems and specific medical application software. Desktop computers, already capable of 20 million instructions per second (MIPS) with massive storage capacities, will continue to evolve and fall in price. Increasingly, perinatologists will develop software packages to facilitate patient care in their own environments. All of these trends will lead to severe fragmentation in medical computing. Simultaneously, however, the need for integrated institutional computer-based data access for quality assurance and fiscal and operations management will increase. Perinatal care will be more regionalized, complex and rigorous with new clinical trial- and effectiveness research-based interventions, as well as molecular diagnosis and therapy. To practice appropriately, clinicians will need to be familiar with computer capabilities. Having been exposed to computer-aided instruction (CAI) at the undergraduate and postgraduate levels, they will except on-line access to detailed and accurate patient information with linkage to laboratory, radiology and other medical databases, as well as to reference databases, such as Medlines and the Oxford Database of Perinatal Trials. Artificial intelligence (AI) software may support perinatal decision making; computerized professional and facility billing will be available.

Variability of adjustments to indices in determining patient risk in biochemical screening.

It has long been appreciated that the measurement of biochemical parameters for prenatal screening for neural tube defects, and later aneuploidy, is not as simple as measuring hemoglobin or hematocrit. Early in the game, it was recognized that there are gestational age curves, and that since alpha-fetoprotein (AFP), for example, is a fetal product, its distribution varies as a function of maternal plasma volume, and therefore the weight of the mother. A number of different adjustment factors have been used for AFP and other parameters for years, with varying degrees of consistency and reliability. Here we review a number of adjustments that have been used, and try to give priority to those that have been most effective. Furthermore, laboratories and programs need to be cognizant that with newer parameters being added, the specifics of requirements will vary on a case-by-case parameter basis, and optimal screening can only be achieved with the appropriate adjustments.
