Vancomycin during delivery hospitalizations for women with group B streptococcus.

ABSTRACT:

Objective

Vancomycin use for intrapartum GBS prophylaxis is not well characterized. The objective of this study was to describe trends in the use of vancomycin among women undergoing vaginal delivery with group B Streptococcus (GBS) colonization.

Methods

An administrative inpatient database that includes medications was analyzed to evaluate antibiotic use in women undergoing vaginal delivery hospitalizations complicated by GBS colonization from January 2006 to March 2015. Patients with other obstetric or infectious indications for antibiotics were excluded. Frequency of use of individual antibiotic agents was determined. The Cochran-Armitage test was used to assess temporal trends. An adjusted log-linear regression model accounting for demographic and hospital factors with vancomycin receipt as the outcome was performed with adjusted risk ratios (aRR) and 95% confidence intervals (CI) as the measure of effect. Hospital level variation in administration of vancomycin was also evaluated.

Results

469,717 deliveries met inclusion criteria and were included in this analysis. Use of vancomycin increased from 0.8% of patients in 2006 to 3.8% of patients in the first quarter of 2015. Comparing 2015 to 2006 both the unadjusted (relative risk 4.89 95% CI 4.26-5.60) and adjusted (aRR 4.52 95% 3.94-5.19) models demonstrated significantly increased likelihood of vancomycin administration. In evaluating hospital level vancomycin use, variation was noted with 8.0% of centers administering vancomycin to ≥6.0% of patients.

Conclusions

Vancomycin is becoming increasingly commonly used for intrapartum GBS prophylaxis. Further research and quality improvements initiatives are indicated to optimize intrapartum GBS antibiotic prophylaxis.

Project description:OBJECTIVE:To estimate whether the diagnosis of asthma is associated with the use of specific uterotonic and antihypertensive medications during delivery hospitalizations. METHODS:We used Perspective, an administrative database, to determine whether women hospitalized for delivery complicated by postpartum hemorrhage or preeclampsia received uterotonics and antihypertensive medications differentially based on the absence or presence of asthma from 2006 to 2015. Given that carboprost and intravenous (IV) labetalol may be associated with asthma exacerbation, adjusted models for receipt of these medications were created with adjusted risk ratios with 95% CIs as measures of effect. Risk for status asthmaticus based on receipt of carboprost and IV labetalol was analyzed. RESULTS:Over the study period, a total of 5,691,178 women were analyzed, of whom 239,915 (4.2%) had preeclampsia and 139,841 postpartum hemorrhage (2.5%). Carboprost was used less frequently in patients with asthma compared with patients with no asthma (11.4% vs 18.0%) in comparison with IV labetalol, which was used more commonly when a diagnosis of asthma was present (18.5% vs 16.7%). In unadjusted analysis, the presence of asthma was associated with a 37% decrease in likelihood of carboprost use and an 11% increase in likelihood of labetalol use. In adjusted analysis, the presence of asthma was associated with a 32% decrease in likelihood of carboprost use (adjusted risk ratio 0.68, 95% CI 0.62-0.74) compared with a 7% decrease in labetalol use (adjusted risk ratio 0.93, 95% CI 0.90-0.97). Risk for status asthmaticus was significantly increased with use of IV labetalol compared with other antihypertensive medications (6.5 vs 1.7/1,000 delivery hospitalizations, P<.01). CONCLUSION:There may be an opportunity to reduce use of ?-blockers and carboprost among patients with asthma. Given their association with status asthmaticus, these drugs should be used cautiously in women with asthma.

Project description:ObjectiveTo characterize use of uterine tamponade and interventional radiology procedures.MethodsThis retrospective study analyzed uterine tamponade and interventional radiology procedures in a large administrative database. The primary outcomes were temporal trends in these procedures 1) during deliveries, 2) by hospital volume, and 3) before hysterectomy for uterine atony or delayed postpartum hemorrhage. Three 3-year periods were analyzed: 2006-2008, 2009-2011, and 2012-2014. Risk of morbidity in the setting of hysterectomy with uterine tamponade and interventional radiology procedures as the primary exposures was additionally analyzed in adjusted models.ResultsThe study included 5,383,486 deliveries, which involved 6,675 uterine tamponade procedures, 1,199 interventional radiology procedures, and 1,937 hysterectomies. Interventional radiology procedures increased from 16.4 to 25.7 per 100,000 delivery hospitalizations from 2006-2008 to 2012-2014 (P<.01), and uterine tamponade increased from 86.3 to 158.1 (P<.01). Interventional radiology procedures use was highest (45.0/100,000 deliveries, 95% CI 41.0-48.9) in the highest and lowest (8.9/100,000, 95% CI 7.1-10.7) in the lowest volume quintile. Uterine tamponade procedures were most common in the fourth (209.8/100,000, 95% CI 201.1-218.5) and lowest in the third quintile (59.8/100,000, 95% CI 55.1-64.4). Interventional radiology procedures occurred before 3.3% of hysterectomies from 2006 to 2008 compared with 6.3% from 2012 to 2014 (P<.05), and uterine tamponade procedures increased from 3.6% to 20.1% (P<.01). Adjusted risks for morbidity in the setting of uterine tamponade and interventional radiology before hysterectomy were significantly higher (adjusted risk ratio [aRR] 1.63, 95% CI 1.47-1.81 and aRR 1.75 95% CI 1.51-2.03, respectively) compared with when these procedures were not performed.ConclusionThis analysis found that uterine tamponade and interventional radiology procedures became increasingly common over the study period, are used across obstetric volume settings, and in the setting of hysterectomy may be associated with increased risk of morbidity, although this relationship is not necessarily causal.

Project description:ObjectiveTo investigate hospitalizations up to 8 years after live birth among women who used assisted reproductive technology (ART) or who were subfertile compared with women who conceived naturally.DesignRetrospective cohort.SettingDeliveries among privately insured women aged ≥18 years between 2004 and 2017 from Massachusetts state vital records were linked to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System and hospital observational/inpatient stays.Patient(s)We compared patients with ART, medically assisted reproduction (MAR), and unassisted subfertile (USF) delivery with those with fertile delivery.Intervention(s)NA.Main outcome measure(s)Postdelivery hospitalization information was derived from the International Classification of Diseases codes for discharges and combined by type. The relative risks and 95% confidence intervals (CIs) of hospitalization for up to the first 8 years postdelivery were modeled.Result(s)Among 492,515 deliveries, 5.6% used ART, 1.6% used MAR, and 1.8% were USF. Compared with fertile deliveries, deliveries that used ART or MAR or were USF were more likely to have hospital utilization (inpatient or observational stay) for any reason for up to 8 years of follow-up (USF, adjusted relative risk [aRR], 1.18 [95% CI, 1.12-1.25]; MAR, aRR, 1.20 [1.13-1.27]; and ART, aRR, 1.29 [1.25-1.34]). Assisted reproductive technology deliveries had an increased risk of hospitalization for conditions of the cardiovascular system (aRR, 1.31 [95% CI, 1.20-1.41]), overweight/obesity (aRR, 1.30 [1.17-1.44]), diabetes (aRR, 1.25 [1.05-1.49]), reproductive tract (aRR, 1.62 [1.47-1.79]), digestive tract (aRR, 1.39 [1.30-1.49]), thyroid (aRR, 2.02 [1.80-2.26]), respiratory system (aRR, 1.13 [1.03-1.24]), and cancer (aRR, 1.40 [1.18-1.65]) up to 8 years after delivery. Deliveries with MAR and subfertility had similar patterns of hospitalization as ART deliveries.Conclusion(s)Women who conceived through fertility treatment or experienced subfertility were at increased risk of subsequent hospitalization resulting from a variety of chronic and acute conditions.
