Single room maternity care: the nursing response.

BACKGROUND: The introduction of single room maternity care in the 1990s necessitated a new approach to nursing education and practice. A focus on perinatal nursing requires competence across the spectrum of labor, delivery, postpartum and newborn care. We sought to evaluate the nursing response to this change by comparing satisfaction with the workplace environment among single room maternity care nurses before and after they worked in the setting and among nurses working in traditional birth settings. METHODS: Six months before the opening of a pilot seven-bed single room maternity care unit, nurses who planned to work in the new unit completed a survey about their satisfaction with aspects of their work environment. Three months after the new unit opened the survey was repeated with this study group and also by a sample of nurses working in the delivery and postpartum areas. RESULTS: Responses indicated that single room maternity care nurses before and after working in the unit were significantly more satisfied with the physical setting, their ability to respond to patients' needs, their opportunity for teaching families, the nursing practice environment, peer support, and their perceived level of competency. They rated their satisfaction significantly higher than that of their colleagues in the traditional delivery and postpartum settings. CONCLUSIONS: The positive transition to single room maternity care by obstetrical nurses was demonstrated by their improved overall satisfaction with the work environment. Evaluation of the nurses' responses to changes in health care delivery has important implications for justifying new clinical approaches and planning for future changes.

Epidural analgesia use as a marker for physician approach to birth: implications for maternal and newborn outcomes.

BACKGROUND: Understanding the association between caregiver belief systems and practice patterns is an emerging area of research. We hypothesized an association between a maternity caregiver's belief system and his or her behavior. The study objective was to determine if a family physician's overall approach to maternity care, as measured by average use of epidural analgesia, was associated with maternal and fetal outcomes. METHODS: Retrospective analysis was conducted of the births of three cohorts of 1992 nulliparous, low-risk women attended by 96 family physicians within an 18-month period in the department of family practice at the largest maternity hospital in Canada. Cohorts were based on the physicians' mean use of epidural analgesia for the women. Family physicians attending fewer than 5 births were excluded. The main outcome measures, by physician epidural utilization cohort, were maternal/newborn morbidity, procedure rates, consultation rates, and length of stay. RESULTS: Family physicians were separated into cohorts based on their mean use of epidural analgesia at rates of: low, 0-30 percent (15 physicians, 263 births); medium, 31-50 percent (55 physicians, 1323 births); and high, 51-100 percent (26 physicians, 406 births). After adjustment for maternal age and race, patients of low versus high epidural users were admitted at a later state of cervical dilation (mean 4.0 vs 3.1 cm), received less electronic fetal monitoring (76.4 vs 87.2%) and oxytocin augmentation (12.2 vs 29.8%), sustained fewer malpositions (occiput posterior or transverse) (23.2 vs 34.2%), had fewer cesarean sections (14.0 vs 24.4%), less obstetric consultation (47.9 vs 63.8%), and fewer newborn special care admissions (7.2 vs 12.8%). CONCLUSIONS: In our setting, high use of epidural analgesia is a marker for a style of practice characterized by malpositions leading to dysfunctional labors and higher intervention rates leading, in turn, to excess maternal/newborn morbidity.

Differences in institutional cesarean delivery rates-the role of pain management.

BACKGROUND: The objective of our study was to compare cesarean delivery rates for low-risk nulliparous women in a community hospital and a tertiary-level maternity hospital and to determine factors influencing those rates. METHODS: We performed a retrospective cohort study of 857 women who did not have obstetric risk factors. The association between hospital and cesarean delivery rate was examined in a multivariate analysis using logistic regression. In a follow-up cohort study, we observed labor management for 24 couples in the community and 26 in the tertiary hospital. RESULTS: The odds of having a cesarean birth (age-adjusted) at the tertiary center were 3.4 (95% confidence interval, 2.1-5.4) compared with the community hospital. Maternal age, cervical dilatation on first examination, and use of epidural analgesia were the primary factors associated with the difference in cesarean delivery rates, with epidural analgesia having the largest effect. Labor support between the 2 hospitals appeared to be similar with the exception of increased use of ambulation in the community hospital and fewer numbers of caregivers for each woman in labor. Women in the tertiary center were more often offered epidural analgesia. CONCLUSIONS: Differences in use of epidural analgesia may contribute to differences in institutional rates of cesarean delivery. Use of epidural analgesia may be related to use of ambulation, consistency of caregiver during labor, availability of epidural, and suggestion for its use by caregivers.

Single room maternity care and client satisfaction.

BACKGROUND: Single room maternity care is the provision of intrapartum and postpartum care in a single room. It promotes a philosophy of family centered care in which one nurse cares for the family consistently throughout the intrapartum and postpartum periods. At B.C. Women's Hospital, a tertiary level obstetric teaching hospital in Vancouver, British Columbia, a seven-bed, single room maternity care unit was developed and opened as a demonstration project. As part of the evaluation of this unit, client satisfaction was compared between women enrolled in single room maternity care and those in a traditional setting. METHOD: The study group included 205 women who were admitted to the single room maternity care unit after meeting the low-risk criteria. Their responses on a satisfaction survey were compared with those of a historical comparison group of 221 women meeting the same eligibility criteria who were identified through chart audits 3 months before the single room maternity care unit was opened. A second, concurrent comparison group comprised 104 women who also met eligibility criteria. RESULTS: Study group women were more satisfied than comparison groups in all areas evaluated, including provision of information and support, physical environment, nursing care, patient education, assistance with infant feeding, respect for privacy, and preparation for discharge. CONCLUSIONS: Single room maternity care was associated with a significant improvement in client satisfaction because of many factors, including the physical setting itself, avoidance of transfers, and improved continuity of nursing care.

Treatment of chronic hepatitis C virus infection with recombinant consensus interferon.

To assess the safety and efficacy of consensus interferon (IFN-Con-1), 55 patients with chronic hepatitis C infection were treated with either 3, 6, 9, 12, or 15 microg IFN-Con-1 s.c. three times a week for 24 weeks, followed by 24 weeks of observation. There was a dose-response relationship with respect to the number of patients with normalized ALT concentrations or undetectable HCV RNA. At the end of the 24-week treatment period, the serum ALT had normalized in 18% of patients given the 3 microg dose and 42% of patients given the 12 microg or 15 microg doses of IFN-Con-1. At the end of the posttreatment observation period, the serum ALT was still normal in 10% of patients given the 3 microg, 6 microg, or 9 microg doses and in 50% of patients given the 15 microg dose. Also, at the end of the 24-week treatment period, 27% of patients given the 3 microg dose and 75% given the 15 microg dose had undetectable serum HCV RNA. At the end of the posttreatment observation period, the proportion of patients with undetectable HCV RNA ranged from 9% of those given the 3 microg dose to 50% of those given the 15 microg dose. Our study indicates that treatment with IFN-Con-1 appears to be safe and effective. In addition, use of 15 microg of IFN-Con-1 resulted in significantly more patients with sustained ALT normalization and absence of HCV RNA 6 months after cessation of therapy compared with treatment with lower doses of IFN-Con-1. Additional trials are underway to confirm these findings.

Determinants of vaginal-perineal integrity and pelvic floor functioning in childbirth.

OBJECTIVES: Our purpose was to evaluate risk factors for severe vaginal-perineal trauma and to ascertain determinants of pelvic floor strength. STUDY DESIGN: Secondary analysis of 459 nulliparous women enrolled in a randomized controlled trial of episiotomy was carried out. In a multivariate analysis we examined the association between (1) sulcus tears, (2) third- or fourth-degree tears, and (3) pelvic floor strength and selected demographic, physiologic, pregnancy-related, and intrapartum factors. RESULTS: Unemployment and shorter second stage of labor were significant predictors of sulcus tears. Episiotomy, forceps use, and birth weight were important predictors of third- and fourth-degree tears. Whereas perineal intactness (use of episiotomy and spontaneous tears) was not influenced by exercise, a strong exercise profile was associated with fewer third- and fourth-degree tears in the presence of episiotomy. Exercise did not influence the rate of sulcus tears. A total of 35% of the variability in postpartum pelvic floor strength was explained by antepartum strength; however, we were only able to identify 5% of the factors contributing to antepartum pelvic floor strength. CONCLUSIONS: Determinants of sulcus tears appear to be present before pregnancy; third- and fourth-degree tears are related to physician management. Exercise mitigates the potential for severe trauma induced by episiotomy.

A randomized trial of a program of early postpartum discharge with nurse visitation.

OBJECTIVE: Our purpose was to compare an early postpartum discharge program versus standard postpartum care. STUDY DESIGN: A randomized controlled trial in a 637-bed university hospital included 175 healthy women recruited at 32 to 38 weeks gestation from physicians' offices and sonograms. Experimental intervention consisted of discharge 6 to 36 hours post partum with nursing care available by telephone or at home at 34 to 38 weeks' gestation and at < or = 48 hours and at 3, 5, and 10 days post partum. The control included a postpartum stay of 48 to 72 hours and standard follow-up. RESULTS: At 1 month no significant differences were seen in perceived maternal competence (Experimental-Control = 4.3 points [95% confidence interval-7.7 to 16.3]), infant weight gain (1.2 gm/ day [-2.8 to 5.2]); identification of significant neonatal hyperbilirubinemia (rate ratio 0.50 [0.10 to 2.51]), infant utilization of health services (rate ratio 0.88 [0.45 to 1.73]), or predominant breast-feeding (adjusted odds ratio 1.25 [0.88 to 1.75]). Program participants did have significantly less frequent infant bilirubin testing (rate ratio 0.39 [0.17 to 0.94]). The program also enhanced perceived maternal competence in recent immigrants (26.9 points [2.7 to 51.5]). CONCLUSIONS: Early postpartum discharge coupled with prenatal, postnatal, and home contacts leads to no apparent disadvantage and may yield benefits for some mothers and infants.

Attitudes toward obstetrics training. Residents surveyed at McGill University and University of Montreal.

OBJECTIVE: To determine family medicine residents' attitudes toward family practice training in obstetrics and neonatology before and after implementation of a modified obstetrics curriculum at McGill University (MG). DESIGN: Two-group pretest and posttest. Fifty-seven respondents, 31 at MG, 26 at University of Montreal (UM), were case matched as first-year and second-year residents. SETTING: Departments of Family Medicine at MG and UM. PARTICIPANTS: Family medicine residents at MG and UM. INTERVENTION: A modified obstetrics curriculum was introduced at MG (study group); no modifications were introduced at UM (control group). First- and second-year residents' attitudes toward the adequacy of training were assessed through responses to a questionnaire administered in July 1992 and July 1994. MAIN OUTCOME MEASURES: Changes in response scores before and after implementation of the modified curriculum. RESULTS: Repeated multivariate analysis of variance (MANOVA) showed respondents believed family practice obstetrics training was adequate in general, but that family practitioners were inadequately trained in emergency obstetric skills. Scores for items assessing neonatology skills increased significantly in the MG group after the intervention. CONCLUSIONS: Residents' overall confidence in their obstetrics training did not appear to improve, but this might be due to a time lag between curriculum modification and attitudinal change. McGill residents' confidence in neonatology skills improved significantly after curriculum modification.
