Oregon's Hard-Stop Policy Limiting Elective Early-Term Deliveries: Association With Obstetric Procedure Use and Health Outcomes.

ABSTRACT: To evaluate the association of Oregon's hard-stop policy limiting early elective deliveries (before 39 weeks of gestation) and the rate of elective early-term inductions and cesarean deliveries and associated maternal-neonatal outcomes.This was a population-based retrospective cohort study of Oregon births between 2008 and 2013 using vital statistics data and multivariable logistic regression models. Our exposure was the Oregon hard-stop policy, defined as the time periods prepolicy (2008-2010) and postpolicy (2012-2013). We included all term or postterm, cephalic, nonanomalous, singleton deliveries (N=181,034 births). Our primary outcomes were induction of labor and cesarean delivery at 37 or 38 weeks of gestation without a documented indication on the birth certificate (ie, elective early term delivery). Secondary outcomes included neonatal intensive care unit admission, stillbirth, macrosomia, chorioamnionitis, and neonatal death.The rate of elective inductions before 39 weeks of gestation declined from 4.0% in the prepolicy period to 2.5% during the postpolicy period (P<.001); a similar decline was observed for elective early-term cesarean deliveries (from 3.4% to 2.1%; P<.001). There was no change in neonatal intensive care unit admission, stillbirth, or assisted ventilation prepolicy and postpolicy, but chorioamnionitis did increase (from 1.2% to 2.2%, P<.001; adjusted odds ratio 1.94, 95% confidence interval 1.80-2.09).Oregon's statewide policy to limit elective early-term delivery was associated with a reduction in elective early-term deliveries, but no improvement in maternal or neonatal outcomes.

Project description:Rationale & objectiveWomen with end-stage kidney disease (ESKD) have decreased fertility and are at increased risk for pregnancy complications. This study examined secular trends and outcomes of obstetric deliveries in a US cohort of women with ESKD.Study designRetrospective cohort study.Setting & participantsWomen aged 18 to 44 years with ESKD and registered in the US Renal Data System from 2002 to 2015.ExposureESKD modality (hemodialysis [HD], peritoneal dialysis, transplantation).OutcomesInfant delivery, preterm delivery, cesarean delivery.Analytical approachUnadjusted delivery rates were expressed as number of delivering women per 1,000 patient-years among women aged 18 to 44 years within each year during the study period, stratified by ESKD modality. Logistic regression models were used to evaluate associations of delivery, preterm delivery, and cesarean delivery with patient characteristics.ResultsThe delivery rate in women undergoing HD and women with a kidney transplant increased from 2.1 to 3.6 and 3.1 to 4.6 per 1,000 patient-years, respectively (P<0.001 for each). The delivery rate in patients undergoing peritoneal dialysis was lower and did not increase significantly (P=0.9). Women with a transplant were less likely to deliver preterm compared with women undergoing HD (OR, 0.92; 95% CI, 0.84-1.00), though more likely have a cesarean delivery (OR, 1.18; 95% CI, 1.06-1.31). For deliveries occurring in the 2012 to 2015 period, 75% of women treated with HD were prescribed 4 or fewer outpatient HD treatments per week and 25% were prescribed 5-plus treatments per week in the 30 days before delivery.LimitationsAscertainment of outcomes and comorbid conditions using administrative claims data.ConclusionsThe delivery rate in women of reproductive age with ESKD increased from 2002 to 2015 among those treated with transplantation or HD. Women with a functioning transplant were less likely to deliver preterm, but more likely to have a cesarean delivery. Prescriptions for outpatient intensified HD for pregnant women with ESKD were infrequent in 2012 to 2015.

Project description:BackgroundCessation of long-term aspirin treatment before noncardiac surgery can cause adverse cardiac events in patients at risk, particularly in those with previous percutaneous coronary interventions (PCI) with stent implantation. The factors influencing the clinical decision to stop aspirin treatment are currently unknown.MethodsIn a single-center, cross-sectional study (retrospective registration: NCT03049566) carried out from February to December 2014, we took a survey among patients scheduled for noncardiac surgery who were under long-term aspirin treatment, and among their treating anesthesiologists using standardized questionnaires on preoperative aspirin use, comorbidities, and risk-benefit assessments. The main objective was to identify factors associated with the decision to stop aspirin treatment. The results of multivariable logistic regressions and intraclass correlations are presented.Results805 patients were included in the study, and 636 questionnaires were returned (203 of which concerned patients with coronary stents). 46.8% of the patients stopped their long-term aspirin treatment before surgery; 38.7% of these patients stopped it too early (>10 days before surgery) or too late (≤ 3 days before surgery). A prior PCI with stent implantation lowered the probability of aspirin cessation (odds ratio [OR] = 0.47 [0.31; 0.72]; p <0.001). On the other hand, patients were more likely to stop their long-term aspirin treatment if it had already been discontinued once before (OR = 4.58 [3.06; 6.84]; p <0.001), if there was a risk of bleeding into a closed space (OR = 4.54 [2.02; 10.22]; p <0.001), if they did not know why they were supposed to take aspirin (OR = 2.12 [1.05; 4.28]; p = 0.036), or if the preoperative consultation with the anesthesiologist occurred <2 days before surgery (OR = 1.60 [1.08; 2.37]; p = 0.018). Patients often assessed the risks related to aspirin cessation lower than their physicians did.ConclusionThis study reveals discordance between guideline recommendations and everyday clinical practice in patients with coronary stents. The early integration of cardiologists and anesthesiologists and a more widespread use of stent implant cards could promote adherence to the guidelines.

Project description:Background:Delayed cord clamping (DCC) results in decreased iron deficiency in infancy. The American College of Obstetrics and Gynecology has called for research on the optimal time to clamp the cord during cesarean deliveries (CD). Our objective was to conduct a pilot trial examining the safety of delayed cord clamping (DCC) for maternal-infant dyads during elective cesarean delivery (CD). Methods:We enrolled 39 dyads [23 at 90 s, 16 at 120 s; (DCC Pilot)] between 10/2013 and 9/2014. We abstracted data from the electronic medical record (EMR) for historical controls (HC) birthing between 1/2012-6/2013 for whom DCC was not performed (n?=?112). Results:Available data for 37 mothers and 30 infants compared to HC revealed 174 (95% CI: 61-286) mL lower mean estimated maternal blood loss [(EBL) mean (SD) mL]: DCC Pilot 691(218) vs. HC 864(442), p =?0.003 and lower incidence of maternal transfusions, DCC Pilot 2.7% vs. HC 18.8%, p =?0.016. There was no significant between group difference between DCC Pilot and HC in other a priori definitions of excess maternal blood loss: a) EBL?>?800 ml, 21.6% vs. 38.8%, p =?0.07 or b) post-op hgb/pre-op hgb?<?80%, 16.7% vs. 20.6%, p =?0.81. There were also no statistically significant between group differences in rates of NICU admission DCC Pilot 8.1% vs. HC 7.1%, p =?1.0., but there was a higher rate of newborn cold stress or hypothermia ?36.2 °C in study subjects, DCC Pilot 27.0% vs. HC 11.9%, p =?0.038.Prevalence of newborn anemia was decreased [DCC pilot 3.3% (1 of 30) vs. HC 40.0% (4 of 10 infants with data), p =?0.012. No infants were polycythemic. Conclusions:These pilot data suggest cord clamping can be delayed to 120 s during elective CD without increased risk of excessive maternal blood loss. More aggressive prevention of infant heat loss may be warranted. A randomized trial to evaluate long-term maternal and infant outcomes is indicated.
