Preoperative Multidisciplinary Team Huddle Improves Communication and Safety for Unscheduled Cesarean Deliveries: A System Redesign Using Improvement Science.

BACKGROUND: Optimal communication between care teams is a critical component in providing safe, timely, and appropriate patient care. Labor and delivery (L&D) units experience rapidly changing clinical scenarios often requiring escalation in care and unplanned cesarean deliveries (CDs). The University of Cincinnati Medical Center (UCMC) is a 550-bed academic level 4 maternal care center with a 13-bed L&D unit in Cincinnati, OH. There are approximately 2500 deliveries/y with a CD rate of 33%. The L&D unit is staffed with dedicated anesthesia personnel 24 hours a day. In our L&D unit, there was widespread dissatisfaction with multidisciplinary communication surrounding unscheduled CD. Near-miss safety events in our obstetric unit were attributed to preoperative communication failures. Initial surveys identified challenges in preoperative communication among nursing, anesthesiology, and obstetric teams leading to potential risk for compromised care. METHOD: Using the UC Health Performance Improvement Way, we first sought to understand the process leading up to unscheduled CD. Change ideas were developed based on observed failures in communication. Interventions were tested and refined through iterative plan-do-study-act (PDSA) cycles. One key intervention was the introduction of a bedside, multidisciplinary, patient-centered, pre-CD huddle attended by nursing, anesthesia, and obstetrics representatives using a standard checklist for critical information. Qualitative patient feedback was elicited to inform change efforts. We compared patient and procedure characteristics from the baseline and huddle implementation phases. MEASURES: Our primary outcome measure was the satisfaction of care team members with communication around unscheduled CD. A secondary outcome was the general anesthesia (GA) rate for unscheduled CD. Our key process measure was adherence to the preoperative huddle. We tracked decision-to-incision interval (DTI) as a balancing measure. RESULTS: Huddle adherence reached 96% for unscheduled CD within 6 months of testing and implementation. A combined survey of anesthesia, nursing, and obstetrics showed that satisfaction scores related to unscheduled CD communication improved from 3.3/5 to 4.7/5 after huddle implementation. The rate of GA use and the median DTI remained unchanged. Patients felt more engaged and reported positive experiences by being a part of the huddle discussion. CONCLUSIONS: In an academic obstetric unit, communication failures surrounding unscheduled CD were identified as a contributor to staff dissatisfaction and perception of safety risk. Implementation of a bedside multidisciplinary pre-CD huddle improved communication between teams and contributed to creating a culture of safety without causing significant delays in care.

Bleeding and thrombotic risk in pregnant women with Fontan physiology.

BACKGROUND/OBJECTIVES: Pregnancy may potentiate the inherent hypercoagulability of the Fontan circulation, thereby amplifying adverse events. This study sought to evaluate thrombosis and bleeding risk in pregnant women with a Fontan. METHODS: We performed a retrospective observational cohort study across 13 international centres and recorded data on thrombotic and bleeding events, antithrombotic therapies and pre-pregnancy thrombotic risk factors. RESULTS: We analysed 84 women with Fontan physiology undergoing 108 pregnancies, average gestation 33±5 weeks. The most common antithrombotic therapy in pregnancy was aspirin (ASA, 47 pregnancies (43.5%)). Heparin (unfractionated (UFH) or low molecular weight (LMWH)) was prescribed in 32 pregnancies (30%) and vitamin K antagonist (VKA) in 10 pregnancies (9%). Three pregnancies were complicated by thrombotic events (2.8%). Thirty-eight pregnancies (35%) were complicated by bleeding, of which 5 (13%) were severe. Most bleeds were obstetric, occurring antepartum (45%) and postpartum (42%). The use of therapeutic heparin (OR 15.6, 95% CI 1.88 to 129, p=0.006), VKA (OR 11.7, 95% CI 1.06 to 130, p=0.032) or any combination of anticoagulation medication (OR 13.0, 95% CI 1.13 to 150, p=0.032) were significantly associated with bleeding events, while ASA (OR 5.41, 95% CI 0.73 to 40.4, p=0.067) and prophylactic heparin were not (OR 4.68, 95% CI 0.488 to 44.9, p=0.096). CONCLUSIONS: Current antithrombotic strategies appear effective at attenuating thrombotic risk in pregnant women with a Fontan. However, this comes with high (>30%) bleeding risk, of which 13% are life threatening. Achieving haemostatic balance is challenging in pregnant women with a Fontan, necessitating individualised risk-adjusted counselling and therapeutic approaches that are monitored during the course of pregnancy.

Pregnancy in Women With a Fontan Circulation: A Systematic Review of the Literature.

BACKGROUND: The Fontan operation has provided life-saving palliation and adult survival for individuals born with single ventricle physiology. Many now seek advice about safe pregnancy. Little data are, however, available, consisting mainly of anecdotal experience and small series. This article seeks to review the published literature and identify lessons learnt from this collective experience. METHODS AND RESULTS: We conducted a systematic review to evaluate maternal and fetal outcomes of pregnancy in women with a Fontan circulation. Among 1150 studies that were screened, 6 studies had sufficient longitudinal data points to qualify for meaningful inclusion, yielding 255 pregnancies in 133 women after Fontan procedure resulting in 115 live births (45%; including reports from 1986 to 2015). There was a total of 137 pregnancy losses (69%), with 115 miscarriages (45%), 19 elective terminations of pregnancy (7%), 2 stillbirths (1%), and 1 ectopic pregnancy (1%).The most common cardiovascular adverse events were supraventricular arrhythmia affecting 8.4% (range, 3%-37%) and heart failure affecting 3.9% (range, 3%-11%) of pregnancies. These complications were successfully managed with conventional approaches. No maternal deaths were reported. Postpartum hemorrhage was the predominant obstetric complication affecting 14% of the patients. Most patients were on antiplatelet agents (27%) or anticoagulants (50%) whereas only a minority (11%) were on neither. Among the 115 live births, 68 were premature (59%), 17 were small for gestational age (20%), and neonatal death occurred in 6 patients (5%). CONCLUSIONS: The most commonly reported cardiovascular complications in patients with Fontan physiology-associated pregnancy were arrhythmia and heart failure. Miscarriages were highly prevalent as was prematurity and intrauterine growth restriction. Postpartum hemorrhage seems to be the most common obstetric complication. Large-scale data sets are needed to confirm these early observations and address the late sequelae of pregnancy in women with a Fontan circulation.
