Mixed methods evaluation of simulation-based training for postpartum hemorrhage management in Guatemala.

BACKGROUND: To assess if simulation-based training (SBT) of B-Lynch suture and uterine balloon tamponade (UBT) for the management of postpartum hemorrhage (PPH) impacted provider attitudes, practice patterns, and patient management in Guatemala, using a mixed-methods approach. METHODS: We conducted an in-country SBT course on the management of PPH in a governmental teaching hospital in Guatemala City, Guatemala. Participants were OB/GYN providers (n = 39) who had or had not received SBT before. Surveys and qualitative interviews evaluated provider knowledge and experiences with B-Lynch and UBT to treat PPH. RESULTS: Multiple-choice surveys indicated that providers who received SBT were more comfortable performing and teaching B-Lynch compared to those who did not (p = 0.003 and 0.005). Qualitative interviews revealed increased provider comfort with B-Lynch compared to UBT and identified multiple barriers to uterine balloon tamponade implementation. CONCLUSIONS: Simulation-based training had a stronger impact on provider comfort with B-Lynch compared to uterine balloon tamponade. Qualitative interviews provided insight into the challenges that hinder uptake of uterine balloon tamponade, namely resource limitations and decision-making hierarchies. Capturing data through a mixed-methods approach allowed for more comprehensive program evaluation.

Changing the landscape of obstetric resident education in low- and middle-income countries using simulation-based training.

OBJECTIVE: To evaluate simulation-based training (SBT) in low- and-middle-income countries (LMIC) and the long-term retention of knowledge and self-efficacy. METHODS: We conducted an SBT course on the management of postpartum hemorrhage (PPH), shoulder dystocia (SD), and maternal cardiac arrest (MCA) in three government teaching hospitals in Guatemala. We evaluated changes in knowledge and self-efficacy using a multiple-choice questionnaire for 46 obstetrics/gynecology residents. A paired Student's t test was used to analyze changes at 1 week and 6 months after the SBT. RESULTS: There was an increase in scores in clinical knowledge of MCA (p < 0. 001, 95% confidence interval [CI] 0.81-1.49) and SD (p < 0.001, 95% CI 0.41-1.02) 1 week after SBT, and a statistically insignificant increase in PPH scores (p = 0.617, 95% CI -0.96 to 0.60). This increase in scores was maintained after 6 months for MCA (p < 0.001, 95% CI 0.69-1.53), SD (p = 0.02 95% CI 0.07-0.85), and PPH (p = 0.04, 95% CI 0.01-1.26). For MCA and SD, the levels of self-efficacy were increased 1 week following training (p < 0.001, 95% CI 0.83-2.30 and p = 0.008, 95% CI 0.60-3.92, respectively), and at 6 months (p < 0.001, 95% CI 0.79-2.42 and p = 0.006, 95% CI 0.66-3.81, respectively). There was a slight increase in PPH self-efficacy scores 1 week after SBT (p = 0.73, 95% CI -6.05 to 4.41), maintained after 6 months (p = 0.38, 95% CI -6.85 to 2.85). CONCLUSION: SBT was found to be an effective and feasible method to increase short- and long-term clinical knowledge and self-efficacy of obstetric emergencies in LMIC.

Expectant management of severe preeclampsia remote from term: the MEXPRE Latin Study, a randomized, multicenter clinical trial.

OBJECTIVE: The objective of the study was to determine whether expectant management of severe preeclampsia prior to 34 weeks of gestation results in improved neonatal outcome in countries with limited resources. STUDY DESIGN: This was a randomized clinical trial performed in 8 tertiary hospitals in Latin America. Criteria of randomization included gestational age between 28 and 33 weeks' gestation and the presence of severe hypertensive disorders. Patients were randomized to steroids with prompt delivery (PD group) after 48 hours vs steroids and expectant management (EXM group). The primary outcome was perinatal mortality. RESULTS: A total of 267 patients were randomized, 133 to the PD group and 134 to the EXM group. Pregnancy prolongation was 2.2 days for the PD group vs 10.3 days for the EXM group (P = .0001). The rate of perinatal mortality (9.4% vs 8.7%; P = .81; relative risk [RR], 0.91; 95% confidence interval [CI], 0.34-1.93) was not improved with expectant management, and neither was the composite of neonatal morbidities (56.4% vs 55.6%; P = .89; RR, 01.01; 95% CI, 0.81-1.26). There was no significant difference in maternal morbidity in the EXM group compared with the PD group (25.2% vs 20.3%; P = .34; RR, 1.24; 95% CI, 0.79-1.94). However, small gestational age (21.7% vs 9.4%; P = .005; RR, 2.27; 95% CI, 1.21-4.14) and abruption were more common with expectant management (RR, 5.07; 95% CI, 1.13-22.7; P = .01). There were no maternal deaths. CONCLUSION: This study does not demonstrate neonatal benefit with expectant management of severe preeclampsia from 28 to 34 weeks. Additionally, a conservative approach may increase the risk of abruption and small for gestational age.
