The Development and Management Uses of a Patient Classification System for a High-Risk Perinatal Center

A patient classification system for a labor and delivery unit, a maternal-fetal intensive care unit, and an antepartum monitored unit is a complex but necessary component for staffing units with frequently changing patient census and varying patient acuity. This article describes the processes used to develop such a classification system and to predict staffing needs, in advance, in four-hour time blocks in the labor and delivery unit and in eight-hour time frames in the maternal-fetal intensive care unit and the antepartum monitored unit. The article also identifies direct nursing care and indirect nursing care activities and defines the levels of care needed.     

Adaptation of the MISSCARE Survey to the Maternity Care Setting

Missed nursing care is an important measure of nursing care quality that is sensitive to nurse staffing and is associated with patient outcomes in medical–surgical and pediatric inpatient settings. Missed nursing care during labor and birth has not been studied, yet childbirth represents the most common reason for hospitalization in the United States. The Missed Nursing Care (MISSCARE) Survey, a measure of medical–surgical nursing quality with substantial evidence for validity and reliability, was adapted to maternity nursing care using data from focus groups of labor nurses, physicians, and new mothers and an online survey of labor nurses. Content validity was evaluated via participant feedback, and exploratory factor analysis was performed to identify the factor structure of the instrument. The modified version, the Perinatal Missed Care Survey, appears to be a feasible and promising instrument with which to evaluate missed nursing care of women during labor and birth in hospitals.     

Frequency of nursing, physician and hospital interventions in women at risk for preterm delivery.

OBJECTIVE: To determine the frequency of nursing intervention, physician treatment and hospital evaluation for women receiving outpatient management services for preterm labor. METHODS: Outpatient services included: patient education; daily and as-needed nursing assessment of monitored uterine activity (MUA) and patient symptoms; treatment compliance; and physician notification for values exceeding established limits. We analyzed service data from women with singleton gestations at 20.0-34.9 weeks. RESULTS: Overall, 307 249 days of data from 10 660 women were reviewed, and 634 983 hours of MUA was assessed. On 53 665 (17.5%) of monitored days, patients exhibited increased MUA and/or symptoms of preterm labor with nursing intervention and reassessment. Physician notification/intervention was required 7316 (13.6%) times, and hospital admission was needed for 3163 (43.2%) of these patients. In the hospital 1400 (44.3%) patients received tocolysis. The mean ( +/- standard deviation) length of hospital stay was 3.2 +/- 7.2 days, and 428 (13.5%) of women remained hospitalized until delivery, with 324 (10.2%) delivering within 48 h. CONCLUSION: In this population of women receiving outpatient preterm-labor management services, 95.1% of excessive MUA or patient-reported symptoms of preterm labor were managed on an outpatient basis. Outpatient management allowed for appropriate identification and triage of women requiring hospital admission.     

Essential Program Components for Perinatal Home Care

Home care will continue to be a rapidly expanding area of health care. This growth will be evident in the perinatal nursing specialty. There are multiple models for delivery of perinatal home services. In each case, consideration needs to be given to licensing and other standards; to operational areas such as staffing, supplies, equipment, and reimbursement; and to quality issues, such as staff development, internal and external customer service, and a continuous quality improvement program. Successful marketing of the services requires recognition that the product is nursing care.     

A Nurse Looks at Childbirth Anxiety

Since anxiety is a common denominator in childbirth, it is an excellent target for nursing intervention during labor and delivery. The nurse can apply basic nursing techniques in the physical and emotional support of the patient to reduce and improve the character of the patient's labor.     

Intravenous meperidine during labor: a randomized comparison between nursing- and patient-controlled administration

Preliminary reports about patient-controlled analgesia during labor have been promising. The purpose of this investigation was to compare our experience with meperidine given intravenously by the patient versus by a nurse. Sixty-four healthy women beginning active labor (cervical dilation 3 cm) at term were randomly assigned to either self-administer a 10-mg dose as often as every 20 minutes or have a nurse administer 25-50 mg every 3 hours as requested. The total meperidine dose and consumption rates were greater when administered by the patient than by a nurse. Maternal side effects occurred with similar frequency in both groups, and pain relief was judged to be equivalent. Maternal and umbilical serum concentrations of meperidine at delivery increased in the patient-controlled group if active labor lasted longer than 2 hours. Neonatal naloxone therapy was used more often when meperidine was administered by the patient than by a nurse (five of 31, 16%, versus three of 33, 10%, respectively). Self-administration of intravenous meperidine by the laboring patient was not found to be advantageous over nursing administration, and may pose an increased threat to the infant.     

Getting to havarti: moving toward patient safety in obstetrics

Most health care professionals who are involved in efforts to improve patient safety are aware of James Reason's "Swiss cheese" model of how accidents occur. Some elements and pressures of current obstetric practice may weaken defenses and safeguards against perinatal injury. Several components of obstetric care in labor and delivery units can be used as targets for tightening the "holes" in the Swiss cheese model. These include improving communications, preparing for rare critical events through simulation training, developing protocols for administration of important medications used in labor and delivery (oxytocin, misoprostol, and magnesium sulfate), increasing the in-house presence of obstetricians, developing an effective departmental infrastructure that includes effective peer review, providing risk management education about high-risk clinical areas that have the potential to result in catastrophic injury, and staffing the unit for all contingencies during all hours, day and night. Acceptance by the obstetric medical staff is critical to the implementation of these patient safety elements.     

Biochemical markers predictive of preterm delivery

Preterm delivery is the leading cause of perinatal morbidity and mortality worldwide. Despite a great deal of research into this disease, we still do not understand its pathophysiology. Our treatments for this disease are only marginally effective. Biochemical markers were developed with the hope of giving us new tools to prevent preterm deliveries. Specifically the hope was that they could predict which patients were destined to have a preterm delivery. At the present time these markers perform only satisfactorily at predicting preterm labor. They are expensive and not convenient to use at present. Perhaps more importantly, though, these markers have given us insight into the complexities of preterm delivery. Preterm delivery can arise from many different etiologies. This will lead to research into new treatments as knowledge about preterm delivery is amassed. We know that any number of pathological processes may be involved in any given patient with preterm labor. Biochemical markers have the distinct advantage of being able to determine the specific pathophysiology in a given patient and may allow us to tailor therapy according to the specific problem. In the future it is likely that a careful search for specific pathophysiology will be the only way we can treat this disease effectively. For the present time the biochemical markers will be used only to predict preterm delivery. Ultrasound measurements of the cervix during the pregnancy are likely a faster and less expensive way to accomplish that goal.     

Prostaglandin E2 for induction of labor in patients with premature rupture of membranes at term.

OBJECTIVE: A prospective study comparing three management schemes for patients at term with premature rupture of membranes was performed. STUDY DESIGN: One hundred forty patients were randomized to one of three study groups: prostaglandin E2, placebo, or oxytocin. Patients randomized to prostaglandin E2 and placebo received vaginal suppositories containing 3 mg prostaglandin E2 or glycerin only, respectively; suppositories were administered in a double-blind fashion, on one or two occasions, 6 hours apart. Oxytocin was given only if labor was not established after 12 hours or to augment inadequate labor. In patients randomized to oxytocin labor was induced with intravenous oxytocin. The time interval to delivery, delivery outcome, and complications were analyzed. RESULTS: Patients receiving prostaglandin E2 were more likely to be in labor after one suppository and to be delivered without the addition of oxytocin when compared with placebo. The time interval to delivery was shorter with prostaglandin E2 and oxytocin induction versus placebo ("expectant management"). The incidence of maternal infection was lowest in patients with labor induced by prostaglandin E2. Although the overall cesarean section rate was low, there was a trend toward a lower rate with prostaglandin E2 induction. No adverse effects were observed with prostaglandin E2. CONCLUSION: Prostaglandin E2 can be used successfully to induce labor after premature rupture of membranes at term with greater ease of administration when compared with oxytocin.     

Uterine Contractile Physiology: Applications In Nursing Care and Patient Teaching

A basic review of uterine contractile physiology, with emphasis on practical applications in nursing care and patient teaching, is presented. Specific areas reviewed are terminology, uterine activity during pregnancy and labor, conduction of contractions, and positions for labor and delivery.     

Risk factors for cesarean delivery at presentation of nulliparous patients in labor

OBJECTIVE: To identify risk factors that place a term nulliparous patient in labor at risk for cesarean delivery. METHODS: This was a case-control, chart review study of 325 nulliparous patients presenting in labor at term with singleton vertex fetuses with either cesarean (patients) or vaginal (controls) delivery. Dichotomous variables were analyzed by chi(2) or Fisher exact tests; continuous variables were assessed by the Wilcoxon two-sample test. Multiple logistic regression was used to identify independent risk factors for cesarean delivery, and a model for predicting risk was built and evaluated. RESULTS: In univariate analysis, 22 variables were significantly different between patients and controls. Of 11 that were known within 2 hours of admission, five (change in cervical dilatation, maternal weight, gestational age, fetal station at 2 hours, and preeclampsia) remained independently significant in a multiple logistic regression model for cesarean delivery. The multiple regression model could divide our study population into quintiles in which the lowest risk group had a 5% incidence and the highest risk group had an 88% incidence of cesarean delivery. CONCLUSION: It may be possible to offer early cesarean delivery to patients at highest risk, reducing the potential morbidity of long labor or failed operative vaginal delivery followed by a later cesarean delivery.     

Predicting Nurse Staffing Needs for a Labor and Birth Unit in a Large‐Volume Perinatal Service

This project was designed to test a nurse staffing model for its ability to accurately determine staffing needs for a large‐volume labor and birth unit based on a staffing gap analysis using the nurse staffing guidelines from the Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN). The staffing model and the AWHONN staffing guidelines were found to be reliable methods to predict staffing needs for a large‐volume labor and birth unit.     

Participation: the Key to Learning for Patients in Antepartal Clinics

An approach to patient education which recognized successful participation in the learning process as a key factor in providing information for antepartal clinic patients, known to be poorly motivated, was instituted without changing any system or organization and using a minimal amount of nursing and patient time. Important information on care during pregnancy, labor and delivery, and care of the newborn was shared. Group process also provided a vehicle for expression of feelings, opportunity for reassurance, and direction for particular action. The difficulties inherent in this approach to learning are recognized and recommendations are made for dealing with them.     

Negative fetal fibronectin: who is still treating for threatened preterm labor and does it help?

OBJECTIVE: Fetal fibronectin (fFN) has a high negative predictive value for delivery in the next seven days in patients at risk for preterm birth. Providers sometimes disregard a negative result and manage the patient for threatened preterm labor. Our objective was to identify the rate at which patients with a negative fFN were managed for threatened preterm labor and if delivery outcomes were improved with such management. STUDY DESIGN: Retrospective chart review of 111 patients at a single institution evaluated in the obstetrical triage unit for symptoms of threatened preterm labor with negative fFN results over a 19-month period between November 2004 and June 2006. Charts were reviewed for baseline patient characteristics such as gestational age at presentation to triage and fFN testing, prior obstetrical history, cervical examination and contraction frequency. Gestational age at delivery was documented. Rates of admission to the hospital and treatments for threatened preterm labor in this cohort were reviewed. RESULTS: Thirty-seven of patients (33%) with a negative fFN result were managed for threatened preterm labor (admitted to the hospital, given tocolytics, steroids, or intravenous antibiotics) by their provider. Patients undergoing these interventions were more likely to have cervical dilatation, effacement and were contracting more frequently. Only one of the patients delivered within 7 or 14 days of fFN testing. There was no advantage seen to management of threatened preterm labor in the setting of a negative fFN in terms of pregnancy prolongation, even when analyzing the patients with meaningful clinical findings (dilated 2 cm, effaced >or=80%, or contracting >or=12 times/h). CONCLUSION: Patients with meaningful clinical findings suspicious for preterm labor are more likely to undergo interventions by their physicians in the face of a negative fFN. This management does not improve length of gestation.     

Previous cesarean birth. Trial of labor in women with macrosomic infants

Patients with previous cesarean births who delivered macrosomic infants (greater than or equal to 4,000 gm) during the study periods January 1 to December 31, 1980, and July 1, 1982, to June 30, 1983, were analyzed to determine the impact of fetal weight on a trial of labor (TOL). Of 140 women with macrosomic infants given a TOL, 94 (67%) delivered vaginally. The most common indication for cesarean delivery was cephalopelvic disproportion (CPD). The dehiscence rates were similar when patients who underwent a TOL were compared with those who did not. Factors associated with a successful TOL were a previous vaginal delivery after the original cesarean section, no oxytocin usage during the TOL and an indication for the previous cesarean section other than CPD. The risk associated with a TOL in a patient with a previous cesarean birth and a macrosomic infant appears to be no greater than that encountered in a similar group of patients without uterine scars.     

Trial of labor after cesarean delivery with a lower-segment, vertical uterine incision: Is it safe?

Objective: Our purpose was to assess maternal and perinatal outcomes associated with a trial of labor and attempted vaginal birth after prior low-segment vertical cesarian delivery.Study design: During a 10-year period in a single tertiary hospital, all patients with a prior low-segment uterine incision (whether vertical or transverse) were considered candidates for a trial of labor in the absence of other contraindications or patient refusal. Among the 1137 women who underwent low-segment vertial cesarean delivery, 262 were subsequently delivered of 322 live-born infants, and 174 (54%) of them were identified retrospectively as having attempted vaginal birth. The maternal and perinatal outcomes of patients who did or did not undergo a trial of labor were analyzed and compared.Results: No significant differences between the two patient groups were observed regarding demographic characteristics, antepartum complications, gestational age at delivery (mean 37.4 weeks), birth weight, and cord pH at delivery. Vaginal delivery was accomplished successfully in 144 of 174 (83%) patients who underwent a trial of labor. Abdominal delivery was necessary for 17 mothers with labor disorders and 13 with suspected fetal distress. Postpartum hemorrhage occurred more often in the trial of labor group (7/174 [4.0%] vs 2/148 [1.4%], p not significant), but endometritis developed significantly more often in patients with elective repeat cesarean delivery (16.9% vs 6.3%, p - 0.006)/ Rupture of the low-segment vertical cesarean group scar occurred in 2 patients during a trial of labor (1.1%) versus none in the elective repeat cesarean group. Neither mother experienced fetal extrusion or adverse maternal or fetal sequelae. Frequency of serious neonatal complications (8.1% vs 10%) and neonatal mortality (1.7% vs 2.0%) were similar between groups. All neonatal deaths were a result of extreme prematurity or congenital anomalies.Conclusions: Our experience indicates that a mother with a prior low-segment vertical cesarean delivery can undertake a trial of labor with relative maternal-perinata safety. The likelihood of successful outcome and the incidence of complications are comparable to those of published experience with a trial of labor after a previous low-segment transverse incision.
