Major concerns of women after cesarean delivery.

OBJECTIVE: To identify women's major physiologic, psychologic, and life-style concerns at 2 and 8 weeks after cesarean delivery. DESIGN: Descriptive study with open-ended interviews. SETTING: Large urban hospital affiliated with a major university. PARTICIPANTS: One hundred six women who had unplanned cesarean deliveries and delivered live, full-term neonates. The mean maternal age was 28.7 years. MAIN OUTCOME MEASURES: The major physiologic, psychologic, and life-style concerns. RESULTS: Seven women reported no concerns at both data points. The number of physiologic concerns that the women expressed decreased markedly from 2 to 8 weeks postdelivery, but the number of psychologic and life-style concerns did not. CONCLUSIONS: These findings reinforce the need for prenatal teaching and postnatal follow-up regarding these concerns.

An integrated knowledge-based system to guide the physician during structured reporting.

A routinely used system for report generation, based on direct physician data entry, has been combined with a knowledge-based module. The knowledge-based system is operating in the background, and guides the user by dynamically suggesting diagnoses and generating hints regarding the actual and possible further diagnostic procedures. Hybrid technology with neural networks and rules is used. A laboratory evaluation has shown good agreement between diagnoses suggested by the system and confirmed diagnoses, with a kappa coefficient of 0.85 and an area under the ROC curve of 0.92. In a survey following a 14-day test period, physicians stated that the system was both sensible and helpful. The current application domain is ultrasound reporting.

Preferred vertical gaze direction and observation distance.

Hill and Kroemer (1986) and Kroemer and Hill (1986) found that the preferred vertical direction of gaze is lower with a nearer binocular stimulus than with a more distant one. A model is proposed that relates this phenomenon to characteristics of the resting state of the oculomotor system. Three predictions of the model were tested, based on measurements of the preferred vertical gaze direction and dark vergence in the same subject sample. On average the effect of observation distance on the preferred vertical gaze direction served to reduce the discrepancy between the resting state of vergence, operationally defined as dark vergence, and actual convergence during inspection of the binocular stimulus. Second, dark vergence data from individual subjects could be successfully used to predict whether they raised or lowered their eyes on inspection of a binocular stimulus as compared with the preferred vertical gaze direction while viewing a monocular stimulus. Finally, predictions of the size of the change of the preferred vertical gaze direction on introduction of a binocular stimulus produced only small and non-significant correlations.

Functions of the CNS in early discharge and home followup of very low birthweight infants.

Various studies have been conducted which explore the different functions of the clinical nurse specialist (CNS). This study details the functions of CNSs providing direct patient care before and following hospital discharge of very low birthweight infants and effect on patient outcome. The study reports on CNS interactions with 36 families whose infants were discharged early from the hospital, and who received discharge planning, teaching, and home followup for 18 months.

Clinical specialist pre- and postdischarge teaching of parents of very low birth weight infants.

This study examined the pre- and postdischarge teaching needed by parents of very low birth weight infants (less than or equal to 1,500 g). The sample consisted of 36 families observed from the births of their infants to 18 months' postdischarge. Content analyses yielded five major teaching categories of infant, mother, family, home, and resources. Major predischarge teaching included feeding, recognition of infections, and growth and development. Major postdischarge teaching included feeding, current health problems, growth and development, and managing within the health-care system.

Acute care visits and rehospitalization in women and infants after cesarean birth.

This study, conducted as a randomized clinical trial, focuses on acute care visits and rehospitalizations of mothers whose infants were delivered by cesarean section (n = 122) and infants (n = 123) for 8 weeks after hospital discharge. There were three maternal rehospitalizations. Maternal acute care visits were for wound infections or complications (27 of 34); 21 occurred in the first 4 weeks. Seventy-five percent of infant rehospitalizations were for infection or possible infection; 22 of 31 infant acute care visits occurred in first 4 weeks for bilirubin checks and infant care problems, and 21 of 25 visits in weeks 5 to 8 were for infections. Discharge teaching and home care in first 4 weeks after discharge and issues related to infant infections in the second 4-week period may reduce the need for rehospitalizations and acute care visits in both mothers who had cesarean section and their infants.
