Risk Factors, Etiologies, and Screening Tools for Sepsis in Pregnant Women: A Multicenter Case-Control Study.

BACKGROUND: Given the significant morbidity and mortality of maternal sepsis, early identification is key to improve outcomes. This study aims to evaluate the performance characteristics of the systemic inflammatory response syndrome (SIRS), quick Sequential [Sepsis-related] Organ Failure Assessment (qSOFA), and maternal early warning (MEW) criteria for identifying cases of impending sepsis in parturients. The secondary objective of this study is to identify etiologies and risk factors for maternal sepsis and to assess timing of antibiotics in patients diagnosed with sepsis. METHODS: Validated maternal sepsis cases during the delivery hospitalization from 1995 to 2012 were retrospectively identified at 7 academic medical centers in the United States and Israel. Control patients were matched by date of delivery in a 1:4 ratio. The sensitivity and specificity of SIRS, qSOFA, and MEW criteria for identifying sepsis were calculated. Data including potential risk factors, vital signs, laboratory values, and clinical management were collected for cases and controls. RESULTS: Eighty-two sepsis cases during the delivery hospitalization were identified and matched to 328 controls. The most common causes of sepsis were the following: chorioamnionitis 20 (24.4%), endometritis 19 (23.2%), and pneumonia 9 (11.0%). Escherichia coli 12 (14.6%), other Gram-negative rods 8 (9.8%), and group A Streptococcus 6 (7.3%) were the most commonly found pathogens. The sensitivities and specificities for meeting criteria for screening tools were as follows: (1) SIRS (0.93, 0.63); (2) qSOFA (0.50, 0.95); and (3) MEW criteria for identifying sepsis (0.82, 0.87). Of 82 women with sepsis, 10 (12.2%) died. The mortality rate for those who received antibiotics within 1 hour of diagnosis was 8.3%. The mortality rate was 20% for the patients who received antibiotics after >1 hour. CONCLUSIONS: Chorioamnionitis and endometritis were the most common causes of sepsis, together accounting for about half of cases. Notable differences were observed in the sensitivity and specificity of sepsis screening tools with the highest to lowest sensitivity being SIRS, MEW, and qSOFA criteria, and the highest to lowest specificity being qSOFA, MEW, and SIRS. Mortality was doubled in the cohort of patients who received antibiotics after >1 hour. Clinicians need to be vigilant to identify cases of peripartum sepsis early in its course and prioritize timely antibiotic therapy.

Liposomal Bupivacaine Block at the Time of Cesarean Delivery to Decrease Postoperative Pain: A Randomized Controlled Trial.

OBJECTIVE: To evaluate whether a liposomal bupivacaine incisional block decreases postoperative pain and represents an opioid-minimizing strategy after scheduled cesarean delivery. METHODS: In a single-blind, randomized controlled trial among opioid-naive women undergoing cesarean delivery, liposomal bupivacaine or placebo was infiltrated into the fascia and skin at the surgical site, before fascial closure. Using an 11-point numeric rating scale, the primary outcome was pain score with movement at 48 hours postoperatively. A sample size of 40 women per group was needed to detect a 1.5-point reduction in pain score in the intervention group. Pain scores and opioid consumption, in oral morphine milligram equivalents, at 48 hours postoperatively were summarized as medians (interquartile range) and compared using the Wilcoxon rank-sum test. RESULTS: Between March and September 2017, 249 women were screened, 103 women enrolled, and 80 women were randomized. One woman in the liposomal bupivacaine group was excluded after randomization as a result of a vertical skin incision, leaving 39 patients in the liposomal bupivacaine group and 40 in the placebo group. Baseline characteristics between groups were similar. The median (interquartile range) pain score with movement at 48 hours postoperatively was 4 (2-5) in the liposomal bupivacaine group and 3.5 (2-5.5) in the placebo group (P=.72). The median (interquartile range) opioid use was 37.5 (7.5-60) morphine milligram equivalents in the liposomal bupivacaine group and 37.5 (15-75) morphine milligram equivalents in the placebo group during the first 48 hours postoperatively (P=.44). CONCLUSION: Compared with placebo, a liposomal bupivacaine incisional block at the time of cesarean delivery resulted in similar postoperative pain scores in the first 48 hours postoperatively.

Huddles and Debriefings: Improving Communication on Labor and Delivery.

Interprofessional teams work together on the labor and delivery unit, where clinical care is often unscheduled, rapidly evolving, and fast paced. Effective communication is key for coordinated delivery of optimal care and for fostering a culture of community and safety in the workplace. The preoperative huddle allows for information sharing, cross-checking, and preparation before the start of surgery. Postoperative debriefings allow the operative team to engage in ongoing process improvement. Debriefings after adverse events allow for shared understanding, mutual healing, and help mitigating the harm to potential "second victims."

A Shared Decision-Making Intervention to Guide Opioid Prescribing After Cesarean Delivery.

OBJECTIVE: To assess whether a shared decision-making intervention decreases the quantity of oxycodone tablets prescribed after cesarean delivery. TECHNIQUE: A tablet computer-based decision aid formed the basis of a shared decision-making session to guide opioid prescribing after cesarean delivery. Women first received information on typical trajectories of pain resolution and expected opioid use after cesarean delivery and then chose the number of tablets of 5 mg oxycodone they would be prescribed up to the institutional standard prescription of 40 tablets. EXPERIENCE: From April 11, 2016, to June 10, 2016, 105 women were screened, 75 were eligible, and 51 consented to participate; one patient was excluded after enrollment as a result of prolonged hospitalization. The median number of tablets (5 mg oxycodone) women chose for their prescription was 20.0 (interquartile range 15.0-25.0), which was less than the standard 40-tablet prescription (P<.001). CONCLUSION: A shared decision-making approach to opioid prescribing after cesarean delivery was associated with approximately a 50% decrease in the number of opioids prescribed postoperatively in this cohort compared with our institutional standard prescription. This approach is a promising strategy to reduce the amount of leftover opioid medication after treatment of acute postcesarean pain. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT02770612.
