The Effect of Financial Incentives on Adherence to Glucose Self-Monitoring during Pregnancy among Patients with Insulin-Requiring Diabetes: A Randomized Clinical Trial.

OBJECTIVE: Glucose self-monitoring is critical for the management of diabetes in pregnancy, and increased adherence to testing is associated with improved obstetrical outcomes. Incentives have been shown to improve adherence to diabetes self-management. We hypothesized that use of financial incentives in pregnancies complicated by diabetes would improve adherence to glucose self-monitoring. STUDY DESIGN: We conducted a single center, randomized clinical trial from May 2016 to July 2019. In total, 130 pregnant patients, <29 weeks with insulin requiring diabetes, were recruited. Participants were randomized in a 1:1:1 ratio to one of three payment groups: control, positive incentive, and loss aversion. The control group received $25 upon enrollment. The positive incentive group received 10 cents/test, and the loss aversion group received $100 for >95% adherence and "lost" payment for decreasing adherence. The primary outcome was percent adherence to recommended glucose self-monitoring where adherence was reliably quantified using a cellular-enabled glucometer. Adherence, calculated as the number of tests per day divided by the number of recommended tests per day×100%, was averaged from time of enrollment until admission for delivery. RESULTS: We enrolled 130 participants and the 117 participants included in the final analysis had similar baseline characteristics across the three groups. Average adherence rates in the loss aversion, control and positive incentive groups were 69% (SE=5.12), 57% (SE = 4.60), and 58% (SE=3.75), respectively (p=0.099). The loss aversion group received an average of $50 compared with $38 (positive incentive) and $25 (control). CONCLUSION: In this randomized clinical trial, loss aversion incentives tended toward higher adherence to glucose self-monitoring among patients whose pregnancies were complicated by diabetes, though did not reach statistical significance. Further studies are needed to determine whether use of incentives improve maternal and neonatal outcomes. KEY POINTS: · Self-glucose monitoring is a critical part of diabetes management in pregnancy.. · Loss aversion financial incentives may increase adherence to glucose self-monitoring in pregnancy.. · The impact of testing incentives on maternal and neonatal outcomes requires further investigation..

Redesigned Care Delivery for Insulin-Requiring Diabetes in Pregnancy Improves Perinatal Glycemic Control While Reducing Neonatal Intensive Care Admissions, Length of Stay, and Costs.

Objective: We sought to improve perinatal glycemic control and downstream neonatal outcomes through redesigned ambulatory management for women with insulin-requiring diabetes in pregnancy. Methods: To address gaps in perinatal glycemic management of women with insulin-requiring diabetes in pregnancy, redesigned care delivery (RCD) utilized integrated practice unit and minimally disruptive medicine concepts with incorporation of cellular-enabled glucose monitoring. Primary outcomes of RCD (N = 129) included hemoglobin A1c ([HbA1c], within RCD cohort), and gestational age (GA) at delivery, neonatal intensive care (NICU) admission, and NICU length of stay (LOS) compared with a preredesign care cohort (Pre-RCD; N = 122). Secondary outcomes included facility, payer reimbursement, and program costs. Generalized linear models assessed continuous variables while logistic regression methods assessed categorical outcomes. Results: Utilizing RCD, 92% of women with an initial HbA1c <6.5% maintained glycemic control until delivery, and 67.2% with an initial HbA1c ≥6.5% achieved delivery levels <6.5%. NICU admissions and GA-adjusted LOS decreased significantly [Pre-RCD vs. RCD: NICU admissions, 41.0% vs. 27.3%, p < 0.024; NICU LOS (95% confidence interval [CI]), 21.9 (17.1-26.6) vs. 14.6 (9.1-20.1), p = 0.045]. Every 10 days of redesigned management decreased mean NICU LOS by 1 day. Mean payer neonatal reimbursements decreased over $18,000 per delivery (p = 0.08) compared with implementation costs of $1,942 per delivery. Conclusion: Redesigned perinatal diabetes care with remote glucose monitoring demonstrated improved outcomes and value through downstream neonatal outcomes and lower payer costs. Therefore, subsequent dissemination and sustainability of similar programs' improved outcomes will likely require payer support.

Cellular-Enabled Glucometers and Maternal Glucose Control: A Quality Improvement Initiative.

BACKGROUND: Management of diabetes in pregnancy is burdensome due to self-glucose monitoring, recording, and reporting demands. Cellular-enabled glucometers provide real-time transmission of glucose values independent of internet access and cell phone data plans. We describe a quality improvement (QI) intervention that introduced cellular-enabled glucometers for use during pregnancies complicated by diabetes. METHODS: Our aim was to improve maternal glucose control in a cohort of insulin-requiring pregnant women enrolled in a telemedicine diabetes program. During initial establishment of a QI program, women were offered cellular-enabled glucometers but could elect to keep their standard meter. The primary outcome evaluated was glycosylated hemoglobin A1c (HbA1c) at delivery. RESULTS: Baseline characteristics including initial HbA1c were similar between women using a standard glucometer (n = 45) and those using a cellular-enabled glucometer (n = 72). Women who used a cellular-enabled glucometer had a lower HbA1c at delivery compared to those using a standard glucometer (5.8% vs 6.3%, P = .03). This improvement was particularly notable for women with poor glucose control (defined as HbA1c >6.5%) at initial obstetric visit. Women with poor glucose control who used a cellular-enabled glucose monitor had significantly lower HbA1c at delivery (6.0% vs 6.8%, P = .03) and greater change from initial visit compared to those using a standard glucometer (-2.6% vs -1.4%, P = .02). No statistically significant differences were detected in tracked neonatal outcomes. CONCLUSION: For pregnancies complicated by insulin-requiring diabetes, use of cellular-enabled glucometers as part of a perinatal diabetes program improves glucose control at delivery with timely transmission of accurate values throughout gestation.

Adherence to self-glucose monitoring recommendations and perinatal outcomes in pregnancies complicated by diabetes mellitus.

BACKGROUND: Self-glucose monitoring is critical for the management of diabetes mellitus in pregnancy; yet, validated reports of adherence to testing recommendations and associated perinatal outcomes are limited. OBJECTIVE: Using cloud-based, self-glucose monitoring technology, we sought to answer the following questions: (1) Are there differences in the rates of testing adherence based on type of diabetes mellitus in pregnancy? (2) Is adherence to glucose monitoring recommendations associated with perinatal outcomes in pregnancies that are complicated by diabetes mellitus? We hypothesized that adherence to glucose testing recommendations varies by type of diabetes mellitus and that increased adherence to testing recommendations would be associated with improved perinatal outcomes. STUDY DESIGN: This single-center, prospective cohort study included women with type 2 diabetes mellitus and gestational diabetes mellitus who were enrolled in a perinatal diabetes program at <29 weeks gestation between December 2015 and June 2018. All women received a cellular-enabled glucometer that uploaded glucose values to a cloud-based, Health Insurance Portability and Accountability Act-compliant platform in real time that ensured transmission of accurate glucose values. The primary outcome was adherence to self-glucose monitoring recommendations. Four glucose checks were advised daily, and percentage of adherence was calculated. Secondary outcomes were preeclampsia, cesarean delivery, large-for-gestational-age neonates, and neonatal hypoglycemia. The study was powered to detect a 10% difference in the primary outcome of adherence to advised self-glucose monitoring by diabetes mellitus type. Adjusted risk ratios and 95% confidence intervals were generated with the use of logistic regression. RESULTS: This study included 103 eligible women. Baseline characteristics differed between groups, with women with type 2 diabetes mellitus having higher initial HgbA1c and body mass index when compared with women with gestational diabetes mellitus. No differences were noted in age or parity. Adherence was calculated over 20±6 weeks for women with type 2 diabetes mellitus compared with 9±4 weeks for women with gestational diabetes mellitus. Overall adherence to glucose monitoring was significantly less for women with type 2 diabetes mellitus compared with those with gestational diabetes mellitus. Mean testing adherence rates were 51%, 66%, and 70% for type 2 diabetes mellitus, and gestational diabetes mellitus, class A1 and A2, respectively (P=.016). We found that, for every 10% increase in adherence to testing recommendations, the odds of cesarean delivery, neonatal hypoglycemia, and large-for-gestational-age fetuses decreases by 15-20%. There was no association between adherence and rates of preeclampsia. CONCLUSION: This study shows that overall adherence to testing recommendations differs by diabetes mellitus type and is associated with neonatal outcomes. Improved outcomes with higher adherence may reflect more timely medication adjustments in response to real-time glucose values. Programs aimed at improving adherence could prove beneficial.

Pregnancy-Related Changes of Amino Acid and Acylcarnitine Concentrations: The Impact of Obesity.

Objective Our primary objective was to assess the difference in amino and fatty acid biomarkers throughout pregnancy in women with and without obesity. Interactions between biomarkers and obesity status for associations with maternal and fetal metabolic measures were secondarily analyzed. Methods Overall 39 women (15 cases, 24 controls) were enrolled in this study during their 15- to 20-weeks' visit at the University of Iowa Hospitals and Clinics. We analyzed 32 amino acid and acylcarnitine concentrations with tandem mass spectrometry for differences throughout pregnancy as well as among women with and without obesity (body mass index [BMI] ≥ 35, BMI < 25). Results There were substantial changes in amino acids and acylcarnitine metabolites between the second and third trimesters (nonfasting state) of pregnancy that were significant after correcting for multiple testing (p < 0.002). Examining differences by maternal obesity, C8:1 (second trimester) and C2, C4-OH, C18:1 (third trimester) were higher in women with obesity compared with women without obesity. Several metabolites were marginally (0.002 < p < 0.05) correlated with birth weight, maternal glucose, and maternal weight gain stratified by obesity status and trimester. Conclusions Understanding maternal metabolism throughout pregnancy and the influence of obesity is a critical step in identifying potential mechanisms that may contribute to adverse outcomes in pregnancies complicated by obesity.

Unintended Live Births Following Second Trimester Pregnancy Termination by Labor Induction.

OBJECTIVE: To determine the incidence of live births following labor induction for pregnancy termination in 16-22-week pregnancies. This information is important in order to be able to adequately counsel a pregnant woman regarding the options for pregnancy termination. STUDY DESIGN: We con- ducted a retrospective study over a 10-year period of all pregnancies that underwent labor induction for pregnan- cy termination between 16 and 22 gestational weeks. The indications for pregnancy termination included fetal anomalies and pregnancy complications. RESULTS: Over the 10-year period 94 patients under- went labor induction for pregnancy termination and were included in the study. There were 14 unintended live births. The gestational age at termination was significantly higher in the unintended live births as com- pared to stillbirths, 21.03±0.65 weeks vs. 20.28±1.15 weeks (p<0.05). In fetuses with trisomy 21 the unintended live births were more common. CONCLUSION: Unintended live birth following labor induction between 16 and 22 weeks' gestation occurs in about 15% of cases; however, the duration of heart beat is <2 hours in the majority of cases. The incidence of live birth was more common in more advanced pregnancies but did not differ by the method of induction or duration of labor.

Neonatal survival after prolonged preterm premature rupture of membranes before 24 weeks of gestation.

OBJECTIVE: To evaluate neonatal survival after prolonged preterm premature rupture of membranes (PROM) in the era of antenatal corticosteroids, surfactant, and inhaled nitric oxide. METHODS: A single-center retrospective cohort study of neonates born from 2002-2011 after prolonged (1 week or more) preterm (less than 24 weeks of gestation) rupture of membranes was performed. The primary outcome was survival to discharge. Neonates whose membranes ruptured less than 24 hours before delivery (n=116) were matched (2:1) on gestational age at birth, sex, and antenatal corticosteroid exposure with neonates whose membranes ruptured 1 week or more before delivery (n=58). Analysis used conditional logistic regression for categorical data and Wilcoxon signed rank test for continuous data. RESULTS: The prolonged preterm PROM exposed and unexposed cohorts had survival rates of 90% and 95%, respectively, although underpowered to assess the statistical significance (P=.313). Exposed neonates were more likely have pulmonary hypoplasia (26/58 exposed, 1/114 unexposed, P<.001), pulmonary hypertension (21/56 exposed, 10/112 unexposed, P<.001), and pulmonary air leak (21/58 exposed, 14/114 unexposed, P<.001). Gestational age at rupture (20.4 weeks exposed, 22.3 weeks unexposed, P=.189), length of rupture (3.7 weeks exposed, 6.4 weeks unexposed, P=.717), and lowest maximal vertical pocket before 24 weeks of gestation (0 cm exposed, 1.4 cm unexposed, P=.114) did not discriminate between survivors and nonsurvivors after exposure to prolonged preterm PROM. CONCLUSION: With antenatal steroid exposure and aggressive pulmonary management, survival to discharge after prolonged preterm PROM was 90%. Pulmonary morbidities were common. Of note, the data were limited to women who remained pregnant 1 week or longer after rupture of membranes.

Single umbilical artery: Does side matter?

INTRODUCTION: The aim of this study was to determine if laterality of an absent umbilical artery (AUA) is associated with specific sonographic findings, chromosomal defects or postpartum birth defects. MATERIALS AND METHODS: In this retrospective cohort study, ultrasound reports and medical records of patients who received an obstetric ultrasound at the University of Iowa Hospitals and Clinics with an identified laterality of the AUA from 1989 to 2007 (n = 405) were reviewed. Rates of sonographic abnormalities between fetuses with a right versus left AUA were compared using Fisher's exact test. Adjustments for confounding were made using logistic regression modeling. The significance level was set at 0.05. RESULTS: Right AUAs on ultrasound demonstrate higher unadjusted rates of ultrasound abnormalities with a higher percentage of fetuses with >1 additional abnormality (51.1 vs. 37.0%; p = 0.0043). The left AUA group had a significantly higher percentage of isolated AUA (63.0 vs. 48.8%; p = 0.004). In a multivariate analysis, a sonographic right AUA was significantly associated with gastrointestinal (GI) and genitourinary (GU) abnormalities. No other ultrasonographic and umbilical artery Doppler abnormalities, chromosomal defects or postpartum birth defects were significantly associated with a specific laterality of the AUA. DISCUSSION: Our study identified a significant association between a right AUA and concomitant fetal GI and GU abnormalities. Contrary to previous reports, we conclude that laterality of the AUA may prove to be an easily identified early marker of fetal abnormalities.

Screening for Staphylococcus aureus carriage in pregnancy: usefulness of novel sampling and culture strategies.

OBJECTIVE: The purpose of this study was to determine the most sensitive strategy for the detection of Staphylococcus aureus among pregnant women and newborn infants. STUDY DESIGN: We obtained cultures for S aureus from 5 body sites of women at 35-37 weeks' gestation. We obtained cultures from their newborn infants before hospital discharge. RESULTS: Of 209 women who were screened, 29% of the women had at least 1 culture that was positive for S aureus; 5% of infants were S aureus carriers. The sensitivities of each site for S aureus detection were 52% nares, 50% throat, 13% rectum, 8% vagina, and 10% skin. The most sensitive combination of 2 sites was nares and throat (88%). Perinatal transmission of S aureus occurred in 4 women. Maternal methicillin-resistant S aureus carriage rate was 1%. Two infants carried the USA300 methicillin-resistant S aureus. CONCLUSION: Screening single body sites is insensitive for the detection of S aureus carriage in pregnancy. Sampling nares and throat is essential to the identification of S aureus carriers.

The yeast connection: is Candida linked to breastfeeding associated pain?

OBJECTIVE: The objective of the study was to determine whether the isolation of Candida from breastfeeding women is associated with self-reported pain. STUDY DESIGN: A prospective cohort study was conducted from May 2004 to July 2006. Ninety-eight breastfeeding women were enrolled: 20 women reported breastfeeding associated pain, and 78 women were asymptomatic. Cultures were obtained from breast milk, areolae, and infants' oropharynx. RESULTS: Six of the 20 symptomatic women had breast milk cultures positive for yeast, compared with 6 of 78 controls (30% vs 7.7%, P = .015). Among the 12 women from whom yeast was isolated, 11 grew Candida albicans. Incidence of Staphylococcus aureus isolation did not differ significantly between groups (5 of 20 vs 15 of 78, P > .05). CONCLUSION: C. albicans is found more often in breastfeeding mothers who report pain as compared with asymptomatic breastfeeding mothers. Further studies, including treatment trials, are needed to determine whether Candida plays an etiologic role in breastfeeding associated pain.
