Labor prior to cesarean delivery associated with higher post-discharge opioid consumption.

ABSTRACT:

Background

Severe acute post-cesarean delivery (CD) pain has been associated with an increased risk for persistent pain and postpartum depression. Identification of women at increased risk for pain can be used to optimize post-cesarean analgesia. The impact of labor prior to CD (intrapartum CD) on acute post-operative pain and opioid use is unclear. We hypothesized that intrapartum CD, which has been associated with both increased inflammation and affective distress related to an unexpected surgical procedure, would result in higher postoperative pain scores and increased opioid intake.

Methods

This is a secondary analysis of a prospective cohort study examining opioid use up to 2 weeks following CD. Women undergoing CD at six academic medical centers in the United States 9/2014-3/2016 were contacted by phone two weeks following discharge. Participants completed a structured interview that included questions about postoperative pain scores and opioid utilization. They were asked to retrospectively estimate their maximal pain score on an 11-point numeric rating scale at multiple time points, including day of surgery, during hospitalization, immediately after discharge, 1st week, and 2nd week following discharge. Pain scores over time were assessed utilizing a generalized linear mixed-effects model with the patient identifier being a random effect, adjusting for an a priori defined set of confounders. A multivariate negative binomial model was utilized to assess the association between intrapartum CD and opioid utilization after discharge, also adjusting for the same confounders. In the context of non-random prescription distribution, this model was constructed with an offset for the number of tablets dispensed.

Results

A total of 720 women were enrolled, 392 with and 328 without labor prior to CD. Patients with intrapartum CD were younger, less likely to undergo repeat CD or additional surgical procedures, and more likely to experience a complication of CD. Women with intrapartum CD consumed more opioid tablets following discharge than women without labor (median 20, IQR 10-30 versus 17, IQR 6-30; p = 0.005). This association persisted after adjustment for confounders (incidence rate ratio 1.16, 95% CI 1.05-1.29; p = 0.004). Pain scores on the day of surgery were higher in women with intrapartum CD (difference 0.91, 95% CI 0.52-1.30; adj. p = <0.001) even after adjustment for confounders. Pain scores at other time points were not meaningfully different between the two groups.

Conclusion

Intrapartum CD is associated with worse pain on the day of surgery but not other time points. Opioid requirements following discharge were modestly increased following intrapartum CD.

Project description:BackgroundStrategies to curb overprescribing have focused primarily on the prescriber as the point of intervention. Less is known about how to empower patients to use fewer opioids and decrease the quantity of leftover opioids. Previous studies in nonobstetrical populations suggest that patient counseling about appropriate opioid use improves disposal of unused opioids and overall knowledge about opioid use. Less is known about whether counseling reduces opioid use after hospital discharge.ObjectiveThis study examines whether enhanced discharge counseling on optimal analgesic use after cesarean delivery reduces opioid use and improves proper disposal of unused opioids and opioid use knowledge after hospital discharge.Study designWomen who underwent an uncomplicated cesarean delivery were randomized to enhanced counseling on optimal analgesic use or usual care. Enhanced counseling addressed the following 4 points: (1) pain is normal after cesarean delivery; (2) scheduled ibuprofen should be taken to maintain baseline pain control; (3) opioids should be used sparingly and should be tapered over several days; and (4) all unused opioids should be returned to pharmacy or flushed in a toilet. All participants received 30 tablets of 5 mg hydrocodone-acetaminophen and 30 tablets of 600 mg ibuprofen at discharge. They were contacted 14 days later to determine opioid use and location of leftover opioids and to complete a 10-question analgesic strategies quiz with a score of 1 to 10. We estimated that outcome data on 172 women total would provide an 80% power to detect a 30% reduction in postdischarge opioid use with enhanced counseling.ResultsNotably, 79% of eligible women consented to the study and 175 of 196 participants (84 enhanced counseling, 91 usual care) completed the follow-up. Compared with usual care, the enhanced counseling group was more likely to follow recommendations for proper opioid disposal (risk ratio, 2.3; 95% confidence interval, 1.3-3.9). They also scored significantly higher on the analgesic strategies quiz (10 points [interquartile range, 9-10] vs 8 points [interquartile range, 7-9]; P<.001) than the usual care group. Although the enhanced counseling group used less opioids (7.5 tablets [interquartile range, 2-15] vs 10.0 tablets [interquartile range, 2-16]; P=.55) and a smaller proportion of prescribed opioids (25.0% [6.7-50.0] vs 33.3% [6.7-53.3], P=.55) than the usual care group, differences were not statistically significant. There was no statistically significant evidence of interaction between participant education level and any of the study outcomes.ConclusionEnhanced discharge opioid counseling doubled the frequency of participants reporting proper opioid disposal and improved overall knowledge about the risks associated with opioids. This intervention did not decrease opioid use in a population of women with low overall opioid use. These findings highlight possible methods to intervene on the short-term (misuse and diversion) and long-term (persistent opioid use) consequences of overprescribing.

Project description:BackgroundThe cesarean delivery (CD) rate has been increasing globally. Trial of labor after cesarean delivery (TOLAC) has been used as a key method for the reduction of the CD rate. Little is known, however, about the association between the second-stage duration of TOLAC and adverse maternal and neonatal outcomes. This study evaluated the association between perinatal outcomes and the duration of second-stage labor in women undergoing TOLAC.MethodsA 10-year retrospective cohort study was performed at the Department of Obstetrics and Gynecology, Third Affiliated Hospital of Guangzhou Medical University, between January 2010 and January 2020. Women undergoing TOLAC who reached the second stage of labor were included in this study. Duration of the second stage of labor was examined as a categorical variable (group I: <0.5 h, group II: 0.5-2 h and group III: ≥2 h) and as a continuous variable to evaluate the association with adverse perinatal outcomes by using multivariable regression models and a Cox proportional hazards regression model adjusting for potential confounders.ResultsOf the 1,174 women who met the inclusion criteria, the median (interquartile range) length of the second stage was 0.5 h (0.3-0.9 h). Among them, 1,143 (97.4%) delivered vaginally and 31 underwent an unplanned CD. As the second-stage duration increased, operative vaginal delivery (OVD), CD, and postpartum hemorrhage (PPH) rates increased. Women in group III had higher risks of OVD (aOR = 11.34; 95% CI [5.06-25.41]), CD (aOR = 4.22; 95% CI [1.32-13.43]), and PPH (aOR = 2.43; 95% CI [1.31-4.50]) compared with group I. Correspondingly, blood loss and the oxytocin used to treat PPH increased significantly, while the postpartum hemoglobin reduced significantly in group III compared with group I. The incidence of uterine rupture, uterine atony, cervical laceration, red blood cell transfusion, and intensive care unit admission were similar in all three groups. Neonatal outcomes were not affected by the second-stage duration.ConclusionsWomen undergoing TOLAC with second-stage duration of ≥2 h have higher odds of OVD, unplanned intrapartum CD, and PPH.

Project description:ObjectiveTo assess the impact of a web-based decision aid on patient-centered decision making outcomes among women considering a trial of labor after cesarean (TOLAC) versus planned repeat cesarean delivery.MethodsThe Birth Decision Aid Study (B-READY) was a quasi-experimental pre-post study of two sequential cohorts. From June 18, 2018 to July 31, 2019, 50 women were enrolled in routine care, followed by 50 women who were enrolled in the decision aid group. Inclusion criteria were singleton pregnancies between 19/0 to 36/6 weeks, ≤2 prior cesareans, and no contraindications to TOLAC. The decision aid group viewed the online Healthwise® "Pregnancy: Birth Options After Cesarean" program. Both groups received the same birth options counseling and completed the same online assessment. Primary patient-centered outcomes were knowledge about birth options and shared decision making at online assessment, and informed, patient-centered decision making about her preferred mode of delivery at delivery admission.ResultsAmong 100 women participated in this study (50 per group), the mean gestational age at enrollment was 31 weeks, and 71% or 63/89 women who consented to delivery data abstraction had a cesarean delivery. Women in the patient decision aid group gained more knowledge (defined as score ≥ 75%) about birth options compared to those in the routine care group (72% vs. 32%; adjusted odds ratio, AOR: 6.15 [95% CI: 2.34 to 16.14]), and were more likely to make an informed, patient-centered decision (60% vs. 26%; AOR: 3.30 [95% CI: 1.20 to 9.04]. Women in both groups reported similar involvement in shared decision making, as well as satisfaction and values. More than 90% of decision aid users reported it was a useful tool and would recommend it to other TOLAC-eligible women.ConclusionsA web-based birth options patient-centered decision aid for TOLAC eligible women can be integrated into prenatal Telehealth and may improve the quality of decision making about mode of delivery.Trial registrationThe study was registered with ClinincalTrials.gov and the ID# was NCT04053413 .

Project description:ObjectiveTo evaluate whether cervical ripening with oral misoprostol increases cesarean delivery risk and prolongs time to vaginal delivery compared with vaginal misoprostol in a predominantly overweight population.MethodsThis single center, retrospective cohort study was performed at a tertiary care academic medical center and compared labor induction outcomes with vaginal misoprostol to outcomes with oral misoprostol after a complete institutional shift to oral misoprostol. Labor induction using 25 micrograms vaginal misoprostol in 2013-2014 was compared with 50 micrograms oral misoprostol in 2014-2015. The primary outcome was cesarean delivery. Secondary outcomes included time to vaginal delivery, uterine tachysystole, maternal hemorrhage, and composite adverse neonatal outcomes. Demographics and outcomes were analyzed using standard statistical tests. Multivariable regression models accounting for potential confounders were created for the primary and secondary outcomes with adjusted odds ratios (aOR) as the measures of effect.ResultsThere were 138 women in the oral and 138 women in the vaginal misoprostol groups. In the overall cohort, the median (interquartile range) body mass index was 31.7 (28.2-36.8) and most women (72%) were of either black or Hispanic race or ethnicity. The frequency of cesarean delivery was higher in the oral than the vaginal misoprostol group (32% vs 21%; P=.04). The adjusted odds of cesarean was higher with oral misoprostol (aOR 2.01; 95% CI 1.07-3.76). Among nulliparous women, the frequency of cesarean delivery was 41% in the oral and 28% in the vaginal misoprostol groups (aOR 2.79; 95% CI 1.26-6.19). Women had a longer time to vaginal delivery in the oral compared with vaginal misoprostol group (41 vs 31 hours respectively, P=.01). Tachysystole occurred more frequently with vaginal misoprostol (20% vs 11%; P=.04).ConclusionCompared with vaginal misoprostol, oral misoprostol may be associated with increased risk of cesarean delivery and longer time to vaginal delivery.

Project description:Background and aimsPost-stroke depression (PSD), as one of the common complications after stroke, seriously affects the physical and mental health and functional prognosis of patients. Previous studies have shown that the increase of inflammatory mediators is associated with the occurrence of PSD. Lipocalin 2 (LCN2), as an acute phase protein, is involved in the development of acute ischemic stroke (AIS), and its expression is up-regulated in patients with depression, suggesting that there is a potential correlation between serum LCN2 and depression. The aim of this study was to explore the relationship between serum LCN2 at admission and PSD at discharge.MethodsA total of 358 AIS patients were retrospectively included. All patients had fasting venous blood taken within 24 h of admission to detect serum LCN2. The patients were evaluated by 17-item Hamilton Depression Scale (HAMD) before discharge. Patients with HAMD score > 7 were diagnosed with PSD. The correlation between serum LCN2 and PSD was tested using binary logistic regression analysis.ResultsIn our study, 92 (25.7%) patients were diagnosed with PSD at discharge. According to the serum LCN2 value, the patients were divided into three layers (Tertile1 ≤ 105.24ng/ml; Tertile2: 105.24-140.12ng/ml; Tertile3 ≥ 140.12ng/ml), with T1 layer (the lowest levels) as a reference, after adjusting for multiple potential confounding factors, T3 layer (the highest levels) was independently associated with the occurrence of PSD (odds ratio [OR] = 2.639, 95% confidence interval [CI]: 1.317-5.287, P = 0.006). Similar results were found when the serum LCN2 was analyzed as a continuous variable. The optimal cut-off value of serum LCN2 at admission to predict PSD at discharge was 117.60ng/ml, at this threshold, the sensitivity was 77.2%, and the specificity was 53.4%.ConclusionsHigh serum LCN2 levels at admission are an independent risk factor for PSD in patients with AIS at discharge.

Project description:BackgroundThe incidence of opioid-related death in women has increased 5-fold over the past decade. For many women, their initial opioid exposure will occur in the setting of routine medical care. Approximately 1 in 3 deliveries in the United States is by cesarean, and opioids are commonly prescribed for postsurgical pain management.ObjectiveThe objective of this study was to determine the risk that opioid-naïve women prescribed opioids after cesarean delivery will subsequently become consistent prescription opioid users in the year following delivery and to identify predictors for this behavior.Study designWe identified women in a database of commercial insurance beneficiaries who underwent cesarean delivery and who were opioid naïve in the year prior to delivery. To identify persistent users of opioids, we used trajectory models, which group together patients with similar patterns of medication filling during follow-up, based on patterns of opioid dispensing in the year following cesarean delivery. We then constructed a multivariable logistic regression model to identify independent risk factors for membership in the persistent user group.ResultsA total of 285 of 80,127 (0.36%, 95% confidence interval, 0.32-0.40), opioid-naïve women became persistent opioid users (identified using trajectory models based on monthly patterns of opioid dispensing) following cesarean delivery. Demographics and baseline comorbidity predicted such use with moderate discrimination (c statistic = 0.73). Significant predictors included a history of cocaine abuse (risk, 7.41%; adjusted odds ratio, 6.11, 95% confidence interval, 1.03-36.31) and other illicit substance abuse (2.36%; adjusted odds ratio, 2.78, 95% confidence interval, 1.12-6.91), tobacco use (1.45%; adjusted odds ratio, 3.04, 95% confidence interval, 2.03-4.55), back pain (0.69%; adjusted odds ratio, 1.74, 95% confidence interval, 1.33-2.29), migraines (0.91%; adjusted odds ratio, 2.14, 95% confidence interval, 1.58-2.90), antidepressant use (1.34%; adjusted odds ratio, 3.19, 95% confidence interval, 2.41-4.23), and benzodiazepine use (1.99%; adjusted odds ratio, 3.72, 95% confidence interval, 2.64-5.26) in the year prior to the cesarean delivery.ConclusionA very small proportion of opioid-naïve women (approximately 1 in 300) become persistent prescription opioid users following cesarean delivery. Preexisting psychiatric comorbidity, certain pain conditions, and substance use/abuse conditions identifiable at the time of initial opioid prescribing were predictors of persistent use.

Project description:ObjectiveTrial of labor after cesarean delivery has been mostly studied in the setting of one prior cesarean delivery; controversy remains regarding the risks and benefits of trial of labor for women with two prior cesarean deliveries. This study aimed to examine utilization, success rate, and maternal and neonatal outcomes of trial of labor in this population.MethodsUsing linked hospital discharge and birth certificate data, we retrospectively analyzed a cohort of mothers with nonanomalous, term, singleton live births in California between 2010-2012 and had two prior cesarean deliveries and no clear contraindications for trial of labor. We measured whether they attempted labor and, if so, whether they delivered vaginally. Association of patient and hospital characteristics with the likelihood of attempting labor and successful vaginal birth was examined using multivariable regressions. We compared composite severe maternal morbidities and composite severe newborn complications in those who underwent trial of labor as opposed to planned cesarean delivery using a propensity score-matching approach.ResultsAmong 42,771 women who met sample eligibility criteria, 1,228 (2.9%) attempted labor, of whom 484 (39.4%) delivered vaginally. There was no significant difference in the risk of composite severe maternal morbidities, but there was a modest increase in the risk of composite severe newborn complications among women who attempted labor compared with those who did not (2.0% vs 1.4%, P=.04). After accounting for differences in patient and hospital characteristics, propensity score-matched analysis showed no significant association between trial of labor and the risk of composite severe maternal morbidities (odds ratio [OR] 1.16, 95% CI 0.70-1.91), but trial of labor was associated with a higher risk for the composite of severe newborn complications (OR 1.78, 95% CI 1.04-3.04).ConclusionAmong women with two prior cesarean deliveries, trial of labor was rarely attempted and was successful in 39.4% of attempts. Trial of labor in this population was associated with a modest increase in severe neonatal morbidity.
