RESUMO

OBJECTIVE: To examine the gestational age at and day and time of delivery in current U.S. obstetric practice. METHODS: We examined electronic records from 72 hospitals in 16 states during a 4-month period during 2013. Day of week of delivery, time of day of delivery, and route of delivery were examined in various subpopulations delivering both with and without obstetric intervention. RESULTS: Records of 21,381 women were examined. The distribution curve for gestational age at delivery peaked at 39 weeks both for the entire group and for the subgroup entering labor spontaneously and delivering vaginally without augmentation. Statistical modeling suggests that medical intervention accounts for only a fraction of the shift in distribution peak from 40 to 39 weeks of gestation. Three temporal peaks of total and primary cesarean delivery were seen on weekdays, corresponding to immediate preclinic, lunch time, and immediate postclinic timeframes. These peaks were not seen on weekend days. The risk of nonelective primary cesarean delivery during a weekday was approximately one third higher than on a weekend (relative rate 1.36, confidence interval 1.24-1.49). CONCLUSION: The recently described shift in peak distribution of U.S. gestational age at delivery from 40 to 39 weeks of gestation may reflect an underlying physiologic change in the U.S. population and is not exclusively related to obstetric intervention. During the work week, factors other than medical necessity appear to have a marked association with both timing of delivery and rate of cesarean delivery and may affect up to one third of primary cesarean deliveries.

RESUMO

OBJECTIVE: The purpose of this study was to examine the efficacy of specific protocols that have been developed in response to a previous analysis of maternal deaths in a large hospital system. We also analyzed the theoretic impact of an ideal system of maternal triage and transport on maternal deaths and the relative performance of cause of death determination from chart review compared with a review of discharge coding data. STUDY DESIGN: We conducted a retrospective evaluation of maternal deaths from 2007-2012 after the introduction of disease-specific protocols that were based on 2000-2006 data. RESULTS: Our maternal mortality rate was 6.4 of 100,000 births in just >1.2 million deliveries. A policy of universal use of pneumatic compression devices for all women who underwent cesarean delivery resulted in a decrease in postoperative pulmonary embolism deaths from 7 of 458,097 cesarean births to 1 of 465,880 births (P = .038). A policy that involved automatic and rapid antihypertensive therapy for defined blood pressure thresholds eliminated deaths from in-hospital intracranial hemorrhage and reduced overall deaths from preeclampsia from 15-3 (P = .02.) From 1-3 deaths were related causally to cesarean delivery. Only 7% of deaths were potentially preventable with an ideal system of admission triage and transport. Cause of death analysis with the use of discharge coding data was correct in 52% of cases. CONCLUSION: Disease-specific protocols are beneficial in the reduction of maternal death because of hypertensive disease and postoperative pulmonary embolism. From 2-6 women die annually in the United States because of cesarean delivery itself. A reduction in deaths from postpartum hemorrhage should be the priority for maternal death prevention efforts in coming years in the United States.

RESUMO

OBJECTIVE: To evaluate whether current Joint Commission (JC) exclusion criteria for measure PC-01, "Elective Delivery" before 39 weeks of gestation, accurately identify valid, codeable indications for planned early-term delivery. METHODS: We performed a review and critical analysis of all cases recorded as noncompliant for the measure in a large health care system during the second half of 2012. RESULTS: During the study period, of 107,145 total deliveries, 205 cases were reported as noncompliant with PC-01. Ten percent of compliance fallouts (ie, cases coded as noncompliant) resulted from valid indications for delivery identifiable by International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) coding not included on the JC exclusion list; these were primarily unusual or extreme variations of these conditions. Twenty-five percent of fallouts represented valid indications not represented by an ICD-9-CM code. Eight percent of cases were reported as fallouts as a result of imprecise physician charting; only 2% represented chart abstraction errors. Fifty-five percent of cases involved stated indications for early-term delivery not generally recognized as such by the medical community. Compliance rates of 98% are achievable across a large population using the current ICD-9-CM-based metric for compliance assessment used by the JC (PC-01). The current exclusion list does not appear to be amenable to further improvement by inclusion of more or different ICD-9-CM codes. However, given the low volumes generated using the current PC-01 denominator definition, approximately 60% of facilities would have compliance rates below a 95% benchmark with even a single justified outlier if analyzed on a quarterly basis. CONCLUSION: Our data validate the current JC exclusion criteria for this measure, which identify the vast majority of valid indications for early-term delivery used by obstetrician-gynecologists and identifiable with ICD-9-CM codes. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVE: To examine the relationship between nurse-to-patient staffing ratios and perinatal outcomes in women receiving oxytocin during labor. STUDY DESIGN: A retrospective analysis of perinatal outcomes in women receiving oxytocin for induction or augmentation of labor during 2010. Outcomes examined were fetal distress, birth asphyxia, primary cesarean delivery, chorioamnionitis, endomyometritis, and a composite of adverse events. Frequency of 1:1 nurse-to-patient staffing was determined for each hospital. Outcomes were compared between hospitals categorized into quartiles of staffing ratios. RESULTS: In 208,033 women delivering during 2010, there was no relation between frequency of 1:1 nurse-to-patient staffing ratio and improved perinatal outcomes. Adoption of universal 1:1 staffing in the United States would result in the need for an additional 27,000 labor nurses and a cost of $1.6 billion. CONCLUSION: Available data do not support the imposition of mandatory 1:1 nurse-to-patient staffing ratios for women receiving oxytocin in all U.S. facilities.

RESUMO

We describe a systematic approach to the identification and classification of near-miss events on labor and delivery in a large, national health care system. Voluntary reports of near-miss events were prospectively collected during 2010 in 203,708 deliveries. These reports were analyzed according to frequency and potential severity. Near-miss events were reported in 0.69% of deliveries. Medication and patient identification errors were the most common near-miss events. However, existing barriers were found to be highly effective in preventing such errors from reaching the patient. Errors with the greatest potential for causing harm involved physician response and decision making. Fewer and less effective existing barriers between these errors and potential patient harm were identified. Use of a comprehensive system for identification of near-miss events on labor and delivery units have proven useful in allowing us to focus patient safety efforts on areas of greatest need.

RESUMO

OBJECTIVE: No studies exist that have examined the effectiveness of different approaches to a reduction in elective early term deliveries or the effect of such policies on newborn intensive care admissions and stillbirth rates. STUDY DESIGN: We conducted a retrospective cohort study of prospectively collected data and examined outcomes in 27 hospitals before and after implementation of 1 of 3 strategies for the reduction of elective early term deliveries. RESULTS: Elective early term delivery was reduced from 9.6-4.3% of deliveries, and the rate of term neonatal intensive care admissions fell by 16%. We observed no increase in still births. The greatest improvement was seen when elective deliveries at <39 weeks were not allowed by hospital personnel. CONCLUSION: Physician education and the adoption of policies backed only by peer review are less effective than "hard stop" hospital policies to prevent this practice. A 5% rate of elective early term delivery would be reasonable as a national quality benchmark.

RESUMO

OBJECTIVE: The purpose of this study was to analyze reasons for postpartum readmission. STUDY DESIGN: We conducted a database analysis of readmissions within 6 weeks after delivery during 2007, with extended (180 day) analysis for pneumonia, appendicitis, and cholecystitis. Linear regression analysis, survival curve fitting, and Gehan-Breslow statistic with Holm-Sidak all-pairwise analysis for multiple comparisons were used. Probability values of < .05 were considered significant. RESULTS: Of 222,751 women delivered, 2655 women (1.2%) were readmitted within 6 weeks (0.83% vaginal delivery and 1.8% cesarean section delivery; P < .001). A high percentage of these readmittances occurred within the first 6 weeks: pneumonia (84%), appendicitis (43%), or cholecystitis (46%). Cumulative readmission rates were higher in the first 6 weeks after delivery than in the next 20 weeks (pneumonia curve gradient, 3.7 vs 0.11; appendicitis curve gradient, 1.1 vs 0.36; cholecystitis curve gradient, 6.6 vs 1.7). CONCLUSION: The cause of postpartum readmission is primarily infectious in origin. A recent pregnancy appears to increase the risk of pneumonia, appendicitis, and cholecystitis.
