Project description:ObjectiveTo determine whether patient-perceived pressure from clinicians for labor induction or cesarean delivery is significantly associated with having these procedures.Data sources/study settingListening to Mothers III, a nationally representative survey of women 18-45 years who delivered a singleton infant in a U.S. hospital July 2011-June 2012 (N = 2,400).Study designMultivariate logistic regression analysis of factors associated with perceived pressure and estimation of odds of induction and cesarean given perceived pressure.Principal findingsOverall, 14.8 percent of respondents perceived pressure from a clinician for labor induction and 13.3 percent for cesarean delivery. Women who perceived pressure for labor induction had higher odds of induction overall (adjusted odds ratio [aOR]: 3.51; 95 percent confidence interval [CI]: 2.5-5.0) and without medical reason (aOR: 2.13; 95 percent CI: 1.3-3.4) compared with women who did not perceive pressure. Those perceiving pressure for cesarean delivery had higher odds of cesarean overall (aOR: 5.17; 95 percent CI: 3.2-8.4), without medical reason (aOR: 6.13; 95 percent CI: 3.4-11.1), and unplanned cesarean (aOR: 6.70; 95 percent CI: 4.0-11.3).ConclusionsPatient-perceived pressure from clinicians significantly predicts labor induction and cesarean delivery. Efforts to reduce provider-patient miscommunication and minimize potentially unnecessary procedures may be warranted.

Project description:Cesarean delivery (CD) is one of the most common procedures performed in the United States, accounting for 32% of all deliveries. Postpartum surgical site infection (SSI), wound infection and endometritis is a major cause of prolonged hospital stay and poses a burden to the health care system. SSIs complicate a significant number of patients who undergo CD - 2-7% will experience sound infections and 2-16% will develop endometritis. Many risk factors for SSI have been described. These include maternal factors (such as tobacco use; limited prenatal care; obesity; corticosteroid use; nulliparity; twin gestations; and previous CD), intrapartum and operative factors (such as chorioamnionitis; premature rupture of membranes; prolonged rupture of membranes; prolonged labor, particularly prolonged second stage; large incision length; subcutaneous tissue thickness > 3 cm; subcutaneous hematoma; lack of antibiotic prophylaxis; emergency delivery; and excessive blood loss), and obstetrical care on the teaching service of an academic institution. Effective interventions to decrease surgical site infection include prophylactic antibiotic use (preoperative first generation cephalosporin and intravenous azithromycin), chlorhexidine skin preparation instead of iodine, hair removal using clippers instead of razors, vaginal cleansing by povidone-iodine, placental removal by traction of the umbilical cord instead of by manual removal, suture closure of subcutaneous tissue if the wound thickness is >2 cm, and skin closure with sutures instead of with staples. Implementation of surgical bundles in non-obstetric patients has been promising., Creating a similar patient care bundle comprised evidence-based elements in patients who undergo CD may decrease the incidence of this major complication. Each hospital has the opportunity to create its own CD surgical bundle to decrease surgical site infection.

Project description:BackgroundThe most common complication after cesarean delivery is surgical site infection. Antibiotic prophylaxis reduces infectious morbidity and current anesthetic quality metrics include preincision antibiotic prophylaxis. Recently, studies suggest reductions in infectious morbidity with the addition of azithromycin for unscheduled cesarean delivery. Larger doses of cefazolin are recommended for morbidly obese women, but evidence is conflicting. The aim of this study was to survey anesthesiologists to assess current practice for antibiotic prophylaxis for cesarean delivery.MethodsWe invited a random sample of 10,000 current members of the American Society of Anesthesiologists to complete an online survey about their current practice of antibiotic prophylaxis for cesarean delivery in November 2017. The survey included questions similar to a previous survey on this topic in 2012.ResultsThe response rate was 12.2% (n = 1223). Most respondents had at least 15 years of experience (684, 55.9%), work at a nonteaching or community hospital (729, 59.6%), with >500 cesarean deliveries annually (619, 50.6%), and administer obstetric anesthesia several times a week (690, 56.4%). Routine preincision antibiotic prophylaxis was reported by 1162 (95.0%) of the 1223 respondents, a substantial improvement versus the 63.5% reported in the previous study in 2012. For intrapartum cesarean deliveries, 141 (11.5%) administer azithromycin for unscheduled cesarean deliveries. Those who use cefazolin, 509 (42.5%) administer 3 g for morbidly obese women.ConclusionAdherence to preincision antibiotic prophylaxis for cesarean delivery is very high, a significant improvement within 5 years. A minority of anesthesiologists utilize azithromycin for intrapartum cesarean deliveries. The dose of cefazolin for morbidly obese women varies widely.

Project description:OBJECTIVE:To examine the association of a resident-driven quality initiative with cesarean delivery surgical site infections. METHODS:This was a quasi-experimental, preintervention and postintervention study of women undergoing cesarean delivery at 23 weeks of gestation or greater between January 2015 and June 2018 at a single tertiary care center. We implemented a resident-driven, evidence-based surgical bundle, excluding women who underwent emergency cesarean or had chorioamnionitis. The bundle included routine prophylactic antibiotics (both cefazolin and azithromycin), chlorhexidine alcohol skin preparation, use of clippers instead of a razor, vaginal cleansing with povidone iodine, placental removal by umbilical cord traction, subcutaneous tissue closure if wound thickness greater than 2 cm, suture skin closure, dressing removal between 24 and 48 hours, and use of postoperative chlorhexidine soap. Our primary outcome was surgical site infections (superficial incisional, deep incisional, and organ or space surgical site infections) occurring up to 6 weeks postpartum. Outcomes were compared between the preimplementation period (January 2015-August 2016) and postimplementation period (December 2016-June 2018). Coarsened Exact Matching with k-to-k solution was performed using age, race-ethnicity, body mass index, rupture of membranes, and labor. RESULTS:In total, 1,624 underwent cesarean delivery in the preimplementation and 1,523 postimplementation periods, respectively; 1,100 women in the postimplementation period were matched to 1,100 women in the preimplementation period. The rate of surgical site infections in the unmatched cohort was significantly lower in the postimplementation period compared to those in the preimplementation period (2.2% [33/1,523] vs 4.5% [73/1,624]; odds ratio [OR] 0.47 [95% CI 0.31-0.71]; P<.001). This decrease in the rate of surgical site infections remained statistically significant after matching (1.9% [21/1,100] vs 4.1% [45/1,100]; OR 0.46 [0.27-0.77]; P<.001). CONCLUSION:After implementation of a resident-driven quality initiative using a surgical bundle, we observed a significant decrease in cesarean surgical site infections.

Project description:OBJECTIVE:To examine the rate of surgical site infection according to the choice of antibiotics in women undergoing cesarean delivery. METHODS:We conducted a retrospective cohort study of women undergoing cesarean delivery (labored, unlabored, and scheduled) from 2012 to 2017. Women with chorioamnionitis and those who did not receive any antibiotics were excluded. Our primary outcome was defined a priori as a composite of cellulitis, endometritis, deep wound infection, abdominopelvic abscess, and sepsis. Outcomes were examined according to the choice of antibiotics: cefazolin, a standard alternative (both clindamycin and gentamicin), and inappropriate alternatives (such as clindamycin only). A multivariable logistic regression model was used to calculate the propensity score for each observation, which was the probability of receiving a particular antibiotic regimen. The propensity score-adjusted logistic regression models were conducted to calculate adjusted odds ratios (ORs) and 95% CIs. Firth's penalized likelihood approach was applied to address issues of rare events. RESULTS:Among 6,584 selected women, 6,163 (93.6%), 274 (4.2%), and 147 (2.2%) received cefazolin, a standard alternative, and inappropriate alternatives, respectively. Use of standard alternative antibiotics compared with cefazolin was not associated with increased odds of the primary outcome (crude OR 1.50 [0.92-2.46]; adjusted OR 1.63 [0.97-2.60]) but was associated with increased odds of cellulitis (crude OR 2.07 [1.16-3.70]; adjusted OR 1.93 [1.03-3.31]). Use of inappropriate alternative antibiotics compared with cefazolin was associated with increased odds of the primary outcome (crude OR 4.37 [2.80-6.83]; adjusted OR 4.13 [2.59-6.36]) as well as some components of the composite outcome such as endometritis before discharge (crude OR 6.85 [3.94-11.90]; adjusted OR 6.68 [3.69-11.44]) and cellulitis (crude OR 3.36 [1.78-6.34]; adjusted OR 3.23 [1.63-5.81]). CONCLUSION:Both standard alternative and inappropriate alternatives were associated with increased odds of surgical site infections compared with cefazolin.

Project description:BackgroundThe rate of cesarean delivery is increasing in North America. Surgical site infection following this operation can make it difficult to recover, care for a baby and return home. We aimed to determine the incidence of surgical site infection to 30 days following cesarean delivery, associated risk factors and whether risk factors differed for predischarge versus postdischarge infection.MethodsWe identified a retrospective cohort in Nova Scotia by linking the provincial perinatal database to hospital admissions and physician billings databases to follow women for 30 days after they had given birth by cesarean delivery between Jan. 1, 1997 and Dec. 31, 2012. Logistic regression with generalized estimating equations was used to determine risk factors for infection.ResultsA total of 25 123 women had 33 991 cesarean deliveries over the study period. Of the 25 123, 923 had surgical site infections, giving an incidence rate of 2.7% (95% CI 2.54%-2.89%); the incidence decreased over time. Risk factors for infection (adjusted odds ratios ≥ 1.5) were prepregnancy weight 87.0 kg or more, gaining 30.0 kg or more during pregnancy, chorioamnionitis, maternal blood transfusion, anticoagulation therapy, alcohol or drug abuse, second stage of labour before surgery, delivery in 1997-2000 and delivery in a hospital performing 130-1249 cesarean deliveries annually. Women who gave birth earlier in the study period, those who gave birth in a hospital with 130-949 cesarean deliveries per year and those with more than 1 fetus were at a significantly higher risk for surgical site infection before discharge; women who smoked were at significantly higher risk for surgical site infection after discharge.InterpretationMost risk factors are known before delivery, and some are potentially modifiable. Although the incidence of surgical site infection decreased over time, targeted clinical and infection prevention and control interventions could further reduce the burden of illness associated with this health-care-related infection.

Project description:ImportanceIn recent decades, the global rates of cesarean delivery have rapidly increased. Nonetheless, the influence of cesarean deliveries on surgical complications later in life has been understudied.ObjectiveTo investigate whether previous cesarean delivery increases the risk of reoperation, perioperative and postoperative complications, and blood transfusion when undergoing a hysterectomy later in life.Design, setting, and participantsThis registry-based cohort study used data from Danish nationwide registers on all women who gave birth for the first time between January 1, 1993, and December 31, 2012, and underwent a benign, nongravid hysterectomy between January 1, 1996, and December 31, 2012. The dates of this analysis were February 1 to June 30, 2016.ExposureCesarean delivery.Main outcomes and measuresReoperation, perioperative and postoperative complications, and blood transfusion within 30 days of a hysterectomy.ResultsOf the 7685 women (mean [SD] age, 40.0 [5.3] years) who met the inclusion criteria, 5267 (68.5%) had no previous cesarean delivery, 1694 (22.0%) had 1 cesarean delivery, and 724 (9.4%) had 2 or more cesarean deliveries. Among the 7685 included women, 3714 (48.3%) had an abdominal hysterectomy, 2513 (32.7%) had a vaginal hysterectomy, and 1458 (19.0%) had a laparoscopic hysterectomy. In total, 388 women (5.0%) had a reoperation within 30 days after a hysterectomy. Compared with women having vaginal deliveries, fully adjusted multivariable analysis showed that the adjusted odds ratio of reoperation for women having 1 previous cesarean delivery was 1.31 (95% CI, 1.03-1.68), and the adjusted odds ratio was 1.35 (95% CI, 0.96-1.91) for women having 2 or more cesarean deliveries. Perioperative and postoperative complications were reported in 934 women (12.2%) and were more frequent in women with previous cesarean deliveries, with adjusted odds ratios of 1.16 (95% CI, 0.98-1.37) for 1 cesarean delivery and 1.30 (95% CI, 1.02-1.65) for 2 or more cesarean deliveries. Blood transfusion was administered to 195 women (2.5%). Women having 2 or more cesarean deliveries had an adjusted odds ratio for receiving blood transfusion of 1.93 (95% CI, 1.21-3.07) compared with women having no previous cesarean delivery.Conclusions and relevanceWomen with at least 1 previous cesarean delivery face an increased risk of complications when undergoing a hysterectomy later in life. The results support policies and clinical efforts to prevent cesarean deliveries that are not medically indicated.

Project description:The obesity pandemic in the obstetrical population plus increased frequency of Cesarean delivery (CD) has increased vulnerability to surgical site infection (SSI). Here we characterized the microbiome at the site of skin incision before and after CD. Skin and relevant surgical sites were sampled before and after surgical antisepsis from obese (n?=?31) and non-obese (n?=?27) pregnant women. We quantified bacterial biomass by qPCR, microbial community composition by 16sRNA sequencing, assigned operational taxonomic units, and stained skin biopsies from incision for bacteria and biofilms. In obese women, incision site harbors significantly higher bacterial biomass of lower diversity. Phylum Firmicutes predominated over Actinobacteria, with phylotypes Clostridales and Bacteroidales over commensal Staphylococcus and Propionbacterium spp. Skin dysbiosis increased post-surgical prep and at end of surgery. Biofilms were identified post-prep in the majority (73%) of skin biopsies. At end of surgery, incision had significant gains in bacterial DNA and diversity, and obese women shared more genera with vagina and surgeon's glove in CD. Our findings suggest microbiota at incision differs between obese and non-obese pregnant women, and changes throughout CD. An interaction between vaginal and cutaneous dysbiosis at the incision site may explain the a priori increased risk for SSI among obese pregnant women.
