The road to zero preventable birth injuries

Temporal trends in severe maternal and neonatal trauma during childbirth: a population-based observational study

OBJECTIVE

Instrumental vaginal delivery is associated with birth trauma to infant and obstetric trauma to mother. As caesarean delivery rates increased during the past decades, the rate of instrumental vaginal delivery declined. We examined concomitant temporal changes in the rates of severe birth trauma and maternal obstetric trauma.

DESIGN

A retrospective observational study.

SETTINGS AND PARTICIPANTS

All hospital singleton live births in Washington State, USA, 2004-2013, excluding breech delivery. Severe birth trauma (brain, nerve injury, fractures and other severe birth trauma) and obstetric trauma (third/fourth degree perineal lacerations, cervical/high vaginal lacerations) were identified from hospitalisation data. Pregnancy and delivery characteristics were obtained from birth certificates. Temporal trends were assessed by the Cochran-Armitage test. Logistic regression was used to obtain adjusted ORs (AORs) and 95% CI.

RESULTS

Overall, 732 818 live births were included. The rate of severe birth trauma declined from 5.3 in 2004 to 4.5 per 1000 live births in 2013 (P<0.001). The decline was observed only in spontaneous vaginal delivery, the rates of fractures and other severe birth trauma declined by 5% and 4% per year, respectively (AOR: 0.95, 95% CI 0.94 to 0.97 and AOR: 0.96, 95% CI 0.93 to 0.99; respectively). The rate of third/fourth degree lacerations declined in spontaneous vaginal delivery from 3.5% to 2.3% (AOR: 0.95; 95% CI 0.94 to 0.95) and in vacuum delivery from 17.3% to 14.5% (AOR: 0.97, 95% CI 0.96 to 0.98). Among women with forceps delivery, these rates declined from 29.8% to 23.4% (AOR: 0.98, 95% CI 0.96 to 1.00).

CONCLUSION

While the rates of fractures and other birth trauma declined among infants delivered by spontaneous vaginal delivery, the rate of birth trauma remained unchanged in instrumental vaginal delivery and caesarean delivery. Among mothers, the rates of severe perineal lacerations declined, except for women with forceps delivery.

Maternal clinical diagnoses and hospital variation in the risk of cesarean delivery: analyses of a National US Hospital Discharge Database

BACKGROUND

Cesarean delivery is the most common inpatient surgery in the United States, where 1.3 million cesarean sections occur annually, and rates vary widely by hospital. Identifying sources of variation in cesarean use is crucial to improving the consistency and quality of obstetric care. We used hospital discharge records to examine the extent to which variability in the likelihood of cesarean section across US hospitals was attributable to individual women's clinical diagnoses.

METHODS AND FINDINGS

Using data from the 2009 and 2010 Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project--a 20% sample of US hospitals--we analyzed data for 1,475,457 births in 1,373 hospitals. We fitted multilevel logistic regression models (patients nested in hospitals). The outcome was cesarean (versus vaginal) delivery. Covariates included diagnosis of diabetes in pregnancy, hypertension in pregnancy, hemorrhage during pregnancy or placental complications, fetal distress, and fetal disproportion or obstructed labor; maternal age, race/ethnicity, and insurance status; and hospital size and location/teaching status. The cesarean section prevalence was 22.0% (95% confidence interval 22.0% to 22.1%) among women with no prior cesareans. In unadjusted models, the between-hospital variation in the individual risk of primary cesarean section was 0.14 (95% credible interval 0.12 to 0.15). The difference in the probability of having a cesarean delivery between hospitals was 25 percentage points. Hospital variability did not decrease after adjusting for patient diagnoses, socio-demographics, and hospital characteristics (0.16 [95% credible interval 0.14 to 0.18]). A limitation is that these data, while nationally representative, did not contain information on parity or gestational age.

CONCLUSIONS

Variability across hospitals in the individual risk of cesarean section is not decreased by accounting for differences in maternal diagnoses. These findings highlight the need for more comprehensive or linked data including parity and gestational age as well as examination of other factors-such as hospital policies, practices, and culture--in determining cesarean section use.

A window of opportunity: the Louisiana Birth Outcomes Initiative

Louisiana ranks forty-ninth nationally in birth outcomes indicators such as infant mortality and in the percentage of low birth weight and very low birth weight babies. This article describes the formation of the Birth Outcomes Initiative, a statewide targeted investment to reduce poor birth outcomes. It describes how the initiative is a result of the convergence of the triad of well-defined problems, a credible array of potential solutions, and favorable political process. It then describes the Birth Outcomes Initiative in Louisiana, a targeted program to improve health indicators for reproductive-aged women and reduce the incidence of prematurity, low birth weight, and infant mortality.

Perinatal high reliability

Perinatal high reliability is achievable with principles of high reliability organizations. Key organizational, leadership, and clinical characteristics that are essential for developing and sustaining a highly reliable perinatal unit are presented. Interdisciplinary collaboration and commitment to safe care that are founded on standardization are the hallmarks of perinatal high reliability.

Collaboration between obstetricians and neonatalogists: perinatal safety programs and improved clinical outcomes

Although collaboration between obstetricians and neonatologists may seem an obvious way to provide the best quality care to infants and their mothers, this has not always occurred. This article highlights the experiences of several recently published efforts demonstrating how coordinated care resulted in improved clinical outcomes.

A comprehensive perinatal patient safety program to reduce preventable adverse outcomes and costs of liability claims

BACKGROUND

To achieve the goal of safe care for mothers and infants during labor and birth, Catholic Healthcare Partners (CHP; Cincinnati) conducted on-site risk assessments at the 16 hospitals with perinatal units in 2004-2005, with follow-up visits in 2006 through 2008. ON-SITE RISK ASSESSMENTS: In addition to assessing overall organizational risk, the assessments provided each hospital a gap analysis demonstrating up-to-date and outdated practices and strategies and resources necessary to make all practices consistent with current evidence and national guidelines and standards. CRITICAL ASPECTS OF CLINICAL CARE: Review of claims and near-miss data indicate that fetal assessment, labor induction, and second-stage labor care comprise the majority of risk of perinatal harm. Therefore, these clinical areas were the focus of strategies to promote safety. To promote consistency in knowledge and practice, in 2004 a variety of strategies were recommended, including interdisciplinary fetal monitoring education and routine medical record reviews to monitor ongoing adherence to appropriate practice and documentation.

OUTCOMES

Success in implementing essential structural and process components of the perinatal patient safety program have resulted in improvement from 2003 to 2008 in specific outcomes for the 16 perinatal units surveyed, including reduction of perinatal harm, number of claims, and costs of claims.

FUTURE DIRECTIONS

The program continues to evolve with modifications as needed as more evidence becomes available to guide best perinatal practices and new guidelines/standards are published. A patient safety program guided and supported by a health care system can result in safer clinical environments in individual hospitals and in decreased risk of preventable perinatal harm and liability costs.
