Cesarean Rates (cesarean + rate)
Selected AbstractsOutcomes of multifetal pregnanciesJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 1 2007Ounjai Kor-anantakul Abstract Aim:, To determine the outcomes of multifetal pregnancies and to compare maternal and neonatal complications between spontaneously conceived and assisted reproductive therapy. Methods:, A retrospective analysis was conducted of the information from medical records relating to all multifetal pregnancies. The outcomes were analyzed and used for a comparison between spontaneous and assisted multifetal pregnancies. Results:, There were 387 multifetal pregnancies during the study period, which was 1.3% of all the deliveries; 334 cases (86.3%) were spontaneous conceptions and 53 cases (13.7%) were the result of assisted reproductive therapy. Higher-order fetuses (,3) represented 8% of all multifetal pregnancies, 13% in the spontaneous group and 87% in the assisted group. The overall cesarean delivery rate was 73.9%. The assisted reproductive therapy group had a cesarean rate of 90.6% compared with 71.3% in the spontaneous group (P = 0.008). The assisted multifetal pregnancy group had more preterm labors and a longer maternal hospital stay than the spontaneous group. One maternal death occurred in the assisted group. The main causes of early neonatal death were prematurity, infection and congenital malformation. The newborns in the assisted group had more complications than the spontaneous group; most notable were respiratory distress syndrome, newborn intensive care admission, infection and longer hospital stay (6 days vs 15 days, P < 0.001). More complications occurred in higher-order fetuses than with twins. Conclusions:, Assisted multifetal pregnancies were more likely to be delivered by cesarean section and had a higher rate of higher-order fetuses, preterm birth and neonatal prematurity-related complications with a longer hospital stay in both mothers and newborns, than spontaneous multifetal pregnancies.

Mahoney CNM ABSTRACT:,Background: Studying populations with low cesarean delivery rates can identify strategies for reducing unnecessary cesareans in other patient populations. Native American women have among the lowest cesarean delivery rates of all United States populations, yet few studies have focused on Native Americans. The study purpose was to determine the rate and risk factors for cesarean delivery in a Native American population. Methods: We used a case-control design nested within a cohort of Native American live births, , 35 weeks of gestation (n = 789), occurring at an Indian Health Service hospital during 1996,1999. Data were abstracted from the labor and delivery logbook, the hospital's primary source of birth certificate data. Univariate and multivariate analyses examined demographic, prenatal, obstetric, intrapartum, and fetal factors associated with cesarean versus vaginal delivery. Results: The total cesarean rate was 9.6 percent (95% CI 7.2,12.0). Nulliparity, a medical diagnosis, malpresentation, induction, labor length > 12.1 hours, arrested labor, fetal distress, meconium, and gestations < 37 weeks were each significantly associated with cesarean delivery in unadjusted analyses. The final multivariate model included a significant interaction between induction and arrested labor (p < 0.001); the effect of arrested labor was far greater among induced (OR 161.9) than noninduced (OR 6.0) labors. Other factors significantly associated with cesarean delivery in the final logistic model were an obstetrician labor attendant (OR 2.4; p = 0.02) and presence of meconium (OR 2.3; p = 0.03). Conclusions: Despite a higher prevalence of medical risk factors for cesarean delivery, the rate at this hospital was well below New Mexico (16.4%, all races) and national (21.2%, all races) cesarean rates for 1998. Medical and practice-related factors were the only observed independent correlates of cesarean delivery. Implementation of institutional and practitioner policies common to the Indian Health Service may reduce cesarean deliveries in other populations.

We undertook a study of the Department of Defense health care beneficiary population to assess the impact of enrollment in TRICARE Prime, the Department's managed care health plan, on cesarean delivery rates. Methods: Pooled hospital discharge records from 1999,2002 for live, singleton births were analyzed to calculate primary and repeat cesarean rates for TRICARE Prime and non-Prime beneficiaries in the military and civilian hospitals that comprise the Department of Defense health care network. Stepwise logistic regression was used to calculate adjusted odds ratios for clinical indicators for each combination of health plan and hospital setting using the,2difference(p < 0.05)to eliminate nonsignificant variables from the model. Total primary and repeat cesarean rates were compared with primary and repeat cesarean rates for women with no reported clinical complications to account for differences in case mix across subgroups. Statistical significance of the differences calculated for subgroups was assessed using,2. Results: Primary cesarean rates were significantly lower for TRICARE Prime enrollees relative to non-Prime beneficiaries for all race subgroups and three of five age subgroups in military hospitals and four of five age subgroups in civilian hospitals. No significant differences in repeat cesarean rates were observed between Prime and non-Prime beneficiaries within any race or age subgroup. Breech presentation followed by dystocia, fetal distress, and other complications were significant predictors for primary cesarean. Previous cesarean delivery was the leading predictor for repeat cesarean delivery. Primary and repeat cesarean rates observed for military hospitals were consistently lower than rates observed for civilian hospitals within each health plan type and age group. Conclusions: Enrollment in the managed care health plan was significantly associated with lower risk of primary cesarean delivery relative to membership in other health plans offered to Department of Defense health care beneficiaries. Repeat cesarean rates in this population varied independently of health plan type. Primary cesarean delivery was generally associated with clinical complications, whereas previous cesarean delivery was the strongest indictor for a repeat cesarean delivery. A clear explanation of reduced cesarean rates for Prime enrollees remains elusive, but it is likely that factors beyond individual practitioner decision-making were at work. [source] Effect of Preexisting Chronic Disease on Primary Cesarean Delivery Rates by Race for Births in U.S. Military Hospitals, 1999,2002BIRTH, Issue 3 2004Andrea Linton MS This finding suggests that other maternal factors may explain the elevated rates. The purpose of this study was to examine the prevalence of specific chronic diseases identified as risk factors for complications during pregnancy, labor, and delivery, and to explore the strength of each disease to predict a cesarean outcome. Methods: United States military hospital discharge records from 1999 to 2002 for singleton births to women without a previous cesarean were used to calculate primary cesarean and chronic disease rates for diabetes, hypertension, cardiovascular disease, renal disease, anemia, asthma, sexually transmitted diseases, and substance abuse. Stepwise logistic regression was used to calculate adjusted odds ratios for dichotomized race and chronic disease indicators for five maternal age groups using the,2difference(p < 0.05) to identify significant variables for inclusion in the model. Primary cesarean delivery rates were then adjusted for the presence of chronic diseases that were significantly associated with a cesarean outcome. Results: Diabetes, genital herpes, and hypertension were significant predictors of cesarean use among all maternal age groups. Cardiovascular disease, renal disease, asthma, and anemia were predictors in some age groups. The remaining disease conditions were not significant predictors for cesarean delivery. Adjustment of cesarean rates for these chronic diseases did not significantly alter the differences in primary cesarean rates for black and Asian mothers relative to white mothers. Conclusions: The presence of certain chronic conditions before pregnancy may increase the likelihood that a woman will deliver by cesarean section. Adjustment of cesarean rates for the presence of these chronic diseases, however, does not account for the difference in cesarean rates observed for white and minority mothers in the study population. The potential for underreporting of chronic diseases complicates a true assessment of the impact of chronic disease on cesarean delivery rate variations between white and minority women. [source] Effects of Maternal Characteristics on Cesarean Delivery Rates among U.S. Department of Defense Healthcare Beneficiaries, 1996,2002BIRTH, Issue 1 2004Andrea Linton MS Nonclinical factors associated with cesarean delivery include maternal age, race, socioeconomic status, and insurance coverage. This study compared cesarean delivery rates and trends for the U.S. Department of Defense healthcare beneficiary population from 1996 to 2002 with those observed nationally, and assessed the association of these nonclinical factors with cesarean rate variation in the U.S. Department of Defense healthcare beneficiary population. Methods: Hospital discharge and claims records for babies born in the military and civilian hospitals that comprise the Department of Defense healthcare network were used to calculate total and primary cesarean delivery rates and vaginal birth after cesarean (VBAC) rates from 1996 to 2002. Annual cesarean rates for subgroups defined by maternal age, race, and socioeconomic status were calculated to examine rate variations and rate trends within the study population. Pooled data from 1999 to 2002 were used to compare rates across socioeconomic status, stratified by age and race. Statistical significance of the differences calculated for subgroups was assessed using chi-square. Results: Total and primary cesarean delivery rates among the U.S. Department of Defense population were lower than those reported nationally for every year examined. Cesarean delivery and VBAC rate trends in the national and Department of Defense populations were similar. Within the Department of Defense population, total cesarean delivery increased with increasing maternal age and was more highly associated with racial minorities relative to white women. The higher socioeconomic subgroup (defined as active duty, retired, and warrant officers and their families in this study) was generally associated with reduced cesarean delivery rates. Conclusions: Cesarean deliveries are performed less frequently for the U.S. Department of Defense healthcare beneficiary population relative to the national population. Associations between socioeconomic factors and cesarean rates reported for the national population were not apparent in the study population. The consistent pattern of rate variation across racial subgroups in the Department of Defense population suggests that factors beyond those examined in this study are needed to explain the elevated cesarean rates for racial minorities.
