Abstract Objective To assess the relationship between ovarian hyperstimulation syndrome (OHSS) and adverse outcomes using population-based data in the United States. The hypothesis is that patients with OHSS were more likely to deliver preterm and more likely to have hypertensive disorders. Methods This retrospective cohort study identified 94 patients with OHSS and 183 matched referents in eight counties in Minnesota. Data were collected regarding pregnancy history, infertility treatment, and pregnancy outcomes. Using the Rochester Epidemiology Project, study subjects were identified from female patients, aged 18 to 49 years, who were diagnosed with infertility from January 2, 1995 to December 1, 2017, and had a pregnancy greater than 20 weeks' gestation. The primary outcome was preterm delivery or hypertensive disorder of pregnancy incidence in the OHSS group when compared with control patients. Chi-squared test, t test, and multivariate logistic models were used where appropriate. Results Patients with OHSS were more likely to deliver preterm (odds ratio, 2.14; 95% confidence interval, 1.26–3.65; P < 0.01), and their neonates were more likely to be small for gestational age (odds ratio, 4.78; 95% confidence interval, 1.61–14.19; P < 0.01). No significant differences between the groups were observed in any other outcome. Patients with OHSS are more likely to deliver preterm if they undergo fresh transfer compared with a freeze all and subsequent frozen transfer (odds ratio, 3.03, 95% confidence interval, 1.20–7.66, P = 0.02). Conclusion OHSS may lead to preterm birth and small-for-gestational-age neonates, which changes patient counseling and leads to arranging specialized obstetrical care for these patients with OHSS.
Optimizing Post-Cesarean Opioid Prescription Practices at Mayo Clinic: A Quality Improvement Initiative
Objective Optimal prescriptions practices of opioids in the post-cesarean period remain controversial. The primary aim of this initiative was to minimize unused prescription narcotic medication, with a goal of ≤4 leftover pills of 5-mg oxycodone at postoperative day (POD) 14 without affecting pain or satisfaction measures. Study Design This was a prospective longitudinal quality improvement (QI) initiative starting in 2017 utilizing the DMAIC methodology. The measurement phase consisted of validated surveys over 3 months, along with chart review to determine current institutional prescription practices and predictors of outpatient opioid use. Resulting recommendations were adopted, and 1 year later, all patients undergoing cesarean were surveyed for 3 months to determine the effectiveness of the intervention. The study was approved by the Department's QI Committee. Results The response rate was 48%, with 50 of 101 patients completing surveys pre-intervention and 52 of 111 post-intervention. Pre-intervention, surplus medication was predicted (p <0.05) only by the quantity of the opioid prescription. In addition, patients who required ≤37.5 morphine milligram equivalents (MMEs) during the inpatient postoperative stay did not require outpatient narcotic prescriptions. Thereafter, a strategy of matching inpatient use to outpatient prescription 1:1 in a linear regression model (p <0.001, R 2 0.55) optimally matched patient needs up to 200 MME. In the post-intervention survey, mean (SD) prescription decreased from 17.6 (13.7) MME to 8.4 (8.3) MME (p <0.01); 39% compared with 16% of women were discharged without a prescription (p <0.01); and amongst all patients 82.7% compared with 59.6% (p <0.01) had ≤4 pills remaining without differences in patient satisfaction or pain perception. Conclusion This initiative highlights a practical approach to QI utilizing industry techniques in health care. This approach resulted in significant reductions in over-prescription and unused medication, without impacting pain or satisfaction scores. Key Points
Timing of Pregnancy After Ovarian Hyperstimulation Syndrome and Pregnancy-Related Outcomes [35T]
INTRODUCTION: The incidence of ovarian hyperstimulation syndrome (OHSS) after assisted reproduction is approximately 3%. The outcomes of pregnancy in immediate versus delayed pregnancy has not been previously studied. METHODS: A retrospective cohort study was conducted using the Rochester Epidemiology Project Database. Residents of Olmsted County and the surrounding 9 counties with OHSS were identified between 1995 and 2017. Patients were included if they had a pregnancy lasting ≥20 weeks gestation after the diagnosis of OHSS. Background data and pregnancy outcomes were collected. Data were then analyzed using a combination of t-test and Chi squared test. Women with OHSS and same cycle pregnancy were compared to those with subsequent cycle pregnancy. RESULTS: 85 women with OHSS were analyzed, 47 with same-cycle pregnancies and 38 with subsequent cycle pregnancies. Background data did not differ between the two groups for infertility cause, body mass index, gestational age, parity, or number of embryos transferred. OHSS treatment modalities (paracentesis, thoracentesis, hospitalization and medical treatment) did not differ between groups. Patients with same-cycle pregnancies had neonates delivered at 35.6 weeks compared to 38.3 weeks with delayed pregnancies (p=0.0006). Patients with same cycle pregnancies also had lower birth weights compared to patients with delayed pregnancies (3201 g v 2628 g, p=0.003). Incidence of hypertensive disorders, diabetes, placental abruption, thromboembolism, intrauterine fetal death, intrauterine growth restriction, and 1 and 5 minute Apgar scores did not differ between the two groups. CONCLUSION: The data gives new insight into the risk of same-cycle pregnancies in patients with OHSS. Larger studies are needed to confirm the data.
Effect of Hypertensive Disorders of Pregnancy on Clinical Outcomes in Peripartum Cardiomyopathy [39I]
INTRODUCTION: The influence of concurrent hypertensive disorders of pregnancy (HDP) on clinical outcomes of patients with peripartum cardiomyopathy (PPCM) remains incompletely characterized, with authors describing harmful and beneficial relationships with regards to maternal mortality or requirement for cardiac transplantation. METHODS: Ovid Medline, EMBASE, CENTRAL and Scopus were searched for combinations of the following terminology: hypertension, preeclampsia, cardiomyopathy, peripartum, postpartum or puerperium. Eligibility criteria included all articles addressing mortality rates of PPCM with and without HDP using a combination of the European Society of Cardiology 2010 and the National Heart Lung Blood Institute 2000 diagnostic criteria. Two independent reviewers analyzed abstracts and article text to determine eligibility and risk of bias. Risk of bias was determined using the Newcastle-Ottawa scale and a Peto fixed effects model was used to combine odds ratios in a meta-analytic fashion due to the relatively rare frequency of these events. RESULTS: 1838 articles were identified using the search strategy; 148 full text articles were reviewed for eligibility, with 10 observational studies meeting criteria. There was substantial agreement between the two raters for selection (K: 0.799) and for risk of bias (K: 0.851). An overall protective effect was identified [0.565 (95% CI 0.327, 0.974)], with a low degree of heterogeneity (I2 17.66%). No significant differences were found between subgroups-chronic hypertension, access to social medicine, high-income countries and post-diagnosis duration of care greater than 12 months. CONCLUSION: Although the strength of association is weak, concurrent HDP appears to be protective against mortality and need for cardiac transplantation in PPCM.
Influence of Hypertensive Disorders of Pregnancy on Phenotype and Recovery in Peripartum Cardiomyopathy [27L]
INTRODUCTION: Peripartum cardiomyopathy (PPCM) and cardiomyopathy secondary to hypertensive disorders of pregnancy (HDP) are considered to represent distinct cardiac entities (i.e. dilated vs hypertrophic cardiomyopathy). The goal of this systematic review and meta-analysis was to determine if HDP alters the odds of recovery and if baseline left ventricle characteristics are significantly different. METHODS: Ovid Medline, EMBASE, CENTRAL and Scopus were searched for combinations of the following: hypertension, preeclampsia, cardiomyopathy, peripartum, postpartum or puerperium. Articles describing initial left ventricular ejection fraction (LVEF), odds of recovery (EF >50%) or end diastolic diameter (EDD) amongst those with PPCM were included. Two raters analyzed abstracts and full text to determine eligibility and risk of bias. Risk of bias was determined using the Newcastle-Ottawa scale and the DerSimonian-Laird method was used to combine odds ratios. RESULTS: 1838 articles were identified and 148 full text articles were reviewed for eligibility, with 11 observational studies meeting criteria. There was substantial agreement for selection (K: 0.817) and for risk of bias (K: 0.633) between raters. There was no significant difference (mean: 1.837%, 95% CI-4.882, 1.282) in baseline LVEF or EDD (1.837 cm, 95% CI-1.104, 4.778) between patients who developed PPCM +/- HDP. Further, recovery rates between groups were similar with OR of 1.870 (95% CI 0.854, 4.094) and a moderate degree of heterogeneity. CONCLUSION: Counseling regarding eventual recovery of LVEF after PPCM should not be altered due to the presence of HDP; it is unlikely that a phenotypic difference exists in the cardiomyopathy induced by HDP compared to idiopathic PPCM.
