Utilizing the glucose challenge test during pregnancy as a predictor of future diabetes risk

BackgroundGestational Diabetes Mellitus (GDM) presents a significant health concern during pregnancy, predisposing individuals to future diabetes. Despite established postpartum diabetes screening guidelines, adherence to follow-up remains inadequate.AimsThis study aimed to assess the predictive value of the 50-gram glucose challenge test (GCT) for post-pregnancy diabetes development.Materials and methodsA population-based retrospective cohort study was conducted on pregnant women aged 18–45 who underwent GCT screening between November 2007 and July 2017 in a large Israeli community medical organization. Baseline characteristics, GCT results, and diabetes development during follow-up were analyzed using univariate and multivariate Cox regression analyses.ResultsAmong 8,675 women included, 2.4% developed diabetes over a median follow-up of 73.23 months. Elevated GCT results correlated with a higher risk of future diabetes, with a 4% rise in risk per 1 mg/dL increase in glucose above 140 mg/dL. Multivariate analysis revealed a 60-fold rise in the risk of future diabetes in women with GCT results ≥ 200 mg/dL compared to those with GCT < 140 mg/dL, adjusting for age, body mass index, pre-pregnancy glucose, cholesterol, and triglycerides. A GCT result between 140 and 199 mg/dL was a predictor of future diabetes, even when adjusted for GDM based on a subsequent GTT if performed.ConclusionsGCT results during pregnancy strongly predict future diabetes development, with higher GCT values significantly increasing risk. Recognizing abnormal GCT results as indicative of a prediabetic state offers a practical approach for risk stratification, facilitating early diagnosis, and intervention in post-pregnancy care.

Gestational diabetes mellitus – Can we do better with postpartum diabetes screening?

ObjectiveThis study aimed to assess the accuracy of measuring fasting plasma glucose (FPG) within 24–48 h postpartum in women with gestational diabetes mellitus (GDM) as a predictor for abnormal 6–12-week postpartum oral glucose tolerance test (OGTT). Study designA retrospective cohort study (2012–2021) included women with GDM and singleton pregnancies who had FPG levels recorded 24–28 h postpartum and underwent a 6–12-week OGTT. The study compared the predictive accuracy of these FPG readings with the OGTT results. ResultsAmong 3,128 GDM patients, 1,163 (37.2 %) had a postpartum OGTT, with 935 (80.2 %) showing normal FPG (<100 mg/dL). In low-risk GDM cases (managed by lifestyle modifications), 86.15 % had normal postpartum FPG. Normal 24-48hrs FPG readings, especially in low-risk GDM cases, had a high negative predictive value (NPV of 99.3 %) for type-2 diabetes at the 6–12-week OGTT, but a lower NPV (85.8 %) for predicting future glucose intolerance. DiscussionImmediate postpartum FPG testing effectively excludes low-risk GDM women with regards to future type-2 diabetes and reasonably excluded future glucose intolerance in this group. Due to low compliance with standard OGTT, postpartum FPG could be a more practical predictive tool for diabetes in low-risk GDM cases.

"It Empowers You to Empower Them": Health Professional Perspectives of Care for Hyperglycaemia in Pregnancy Following a Multi-Component Health Systems Intervention.

The Northern Territory (NT) and Far North Queensland (FNQ) have a high proportion of Aboriginal and Torres Strait Islander women birthing who experience hyperglycaemia in pregnancy. A multi-component health systems intervention to improve antenatal and postpartum care in these regions for women with hyperglycaemia in pregnancy was implemented between 2016 and 2019. We explored health professional perspectives on the impact of the intervention on healthcare. The RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance) underpinned this mixed-methods evaluation. Clinicians were surveyed before (n = 183) and following (n = 137) implementation. The constructs explored included usual practice and satisfaction with care pathways and communication between services. Clinicians, policymakers and the implementation team were interviewed (n = 36), exploring the impact of the health systems intervention on practice and systems of care. Survey and interview participants reported improvements in clinical practice and systems of care. Self-reported glucose screening practices improved, including the use of recommended tests (72.0% using recommended first-trimester screening test at baseline, 94.8% post-intervention, p < 0.001) and the timing of postpartum diabetes screening (28.3% screening at appropriate interval after gestational diabetes at baseline, 66.7% post-intervention, p < 0.001). Health professionals reported multiple improvements to care for women with hyperglycaemia in pregnancy following the health systems intervention.

Exploring health professionals' knowledge, practices and attitudes regarding gestational diabetes: A cross-sectional Irish national survey.

Gestational diabetes confers short- and long-term risk of mother and offspring health complications. Healthcare professionals such as endocrinologists, diabetes nurses, dietitians, midwives and general practitioners provide gestational diabetes care. We sought to explore healthcare professionals' perspectives on gestational diabetes care during pregnancy and postpartum. Healthcare professionals in the Republic of Ireland, whose role included gestational diabetes care were invited to complete an online 20-item survey between June and September 2022. Social media, professional organisations and personal networks were used for recruitment. Questions included guideline use, postpartum diabetes screening and advice practices. Analyses were performed using SPSS statistical software and free text was coded using NVivo. Seventeen healthcare professions across primary and secondary care settings participated (n = 127). No differences were noted between groups (medical, nursing/midwifery, allied health/other); therefore, findings were reported as a single group. Healthcare professionals reported using multiple different guidelines to support gestational diabetes management (n = 14). The most cited were 'Health Service Executive guidelines' (24.5%), 'local guidelines' (13.2%) and National Institute for Clinical Excellence guidelines (11.3%); 12.3% cited uncertainty, and 27.5% reported not to follow any named guidelines. For postpartum follow-up, 39% felt clear guidelines were available to support practice, 37% felt appropriate systems were in place and 29% reported effective communication between primary and secondary care services. Qualitative findings emphasised a desire for improved communication between systems, participants and providers, clear interdisciplinary guidelines, and adequate resourcing for gestational diabetes management and postpartum diabetes prevention, including comprehensive support and follow-up. System-level challenges and ineffective communication across settings are barriers to optimum postpartum care. Nationally agreed guidelines for best practice gestational diabetes management including postpartum diabetes prevention are needed.

Management of Gestational Diabetes Mellitus: Knowledge, Attitudes, and Practices of Obstetric Doctors in Benghazi, Libya

Abstract Introduction Gestational diabetes mellitus (GDM) adversely affects the mother and fetus. Its diagnosis and management are of great importance to prevent complications. Mothers with GDM are at great risk of developing type 2 diabetes, and metabolic changes can persist for 3 years postdelivery. We assessed the knowledge and practice of obstetricians working at Benghazi Medical Centre (BMC) regarding gestational diabetes. Materials and Methods A cross-sectional descriptive study was conducted at the obstetric department of BMC; we included all postgraduate doctors in July 2021 in the study. The questionnaire included demographic data and questions related to knowledge regarding the definition of GDM, diagnosis, and complications to the mother and fetus. It also included practices toward GDM, including screening, management, follow-up, and postpartum screening for diabetes. Results The total number of doctors who agreed to participate was 102, and the response rate was 72.9%. The mean age of the participants was 35.4 ± 7.2 years; most of the studied group were females 97 (95.1%), 76 (74.5%) were senior house officers, 16 (15.7%) were mid-grades, and 10 (9.8%) were seniors. Most working obstetricians, 76 (74.5%), had less than 10 years of experience. One hundred (98%) participants heard about GDM, and only 39 (38.2%) correctly defined GDM. Regarding the threshold for fasting glucose to diagnose GDM, only 11 (10.8%) gave a right answer of 92 mg/dL. Most participants had a good knowledge of GDM risk factors and complications. Regarding follow-up, only 35 (34.3%) participants provided the correct answer, and only 27 (26.5%) mentioned insulin as the medical treatment of choice. Conclusion Although most of our studied group had contact with GDM patients, most needed basic knowledge regarding definition, diagnosis, and screening. Different opinions regarding diagnostic thresholds and management practices were observed. We recommended the establishment of a gestational diabetes clinic with the cooperation of endocrinologists and obstetricians, as well as local guidelines.

Indications for the Postpartum Oral Glucose Tolerance Test.

Gestational diabetes mellitus (GDM) affects more than 50 000 pregnant women in Germany every year. In postpartum diabetes screening, a 75 g oral glucose tolerance test (OGT) is recommended. This is time-consuming and can have side effects, and only 40% of mothers take it. The determination of pre-test probabilities might obviate the need for OGT except in women who are at particular risk. We analyzed 5444 cases of GDM from the GestDiab registry over the period 2015-2019. The pretest probabilities of a postpartum diagnosis of diabetes mellitus (DM) or prediabetes were calculated on the basis of clinical variables including postpartum venous fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c). In 0.77% of mothers with a history of GDM in whom DM was not detected by FPG or HbA1c, postpartum DM was diagnosed on the basis of the 2-hour value in the OGT. Individual estimation of the pre-test probability of a diagnosis by OGT of postpartum DM or prediabetes was possible with the aid of the FPG and HbA1c values and clinical predictors including insulin treatment during pregnancy, obesity, GDM diagnosed before 24 weeks of gestation, age over 35, and a 1-hour value in the diagnostic OGT during pregnancy of 180 mg/dL (10.0 mmol/L) or above. The pretest probability of postpartum DM in the study group ranged from 0.11% to 4.17%, and that of postpartum prediabetes from 6.4% to 16.3%. The probability of a diagnosis of postpartum diabetes by OGT after GDM can be estimated in postpartum screening on the basis of various parameters. This enables risk-adapted counseling of the affected women along with a long-term strategy for diabetes prevention and follow-up. The findings of our study should be verified by further research.

Digital health outreach to promote postpartum screening after gestational diabetes: A randomized factorial pilot study

ObjectiveWe examined the acceptability and feasibility of a multi-component digital health outreach intervention to promote uptake of guideline-recommended postpartum screening for type 2 diabetes among patients with gestational diabetes (GDM). MethodsWe conducted a 24 randomized factorial experiment as part of the Multiphase Optimization Strategy (MOST) preparation phase for developing behavioral interventions. Participants with current or recent GDM in an integrated healthcare system were randomized to receive an outreach message with up to four intervention components, designed to be self-administered in about 10 min and efficiently delivered online via REDCap: a streamlined values affirmation, personalized information on diabetes risk, an interactive motivational interviewing-based component, and an interactive action planning component. Patient-reported acceptability and feasibility outcomes were assessed via survey. ResultsAmong 162 participants, 72% self-identified with a racial/ethnic minority group. Across components, acceptability scores averaged 3.9/5; ≥91% of participants read most or all of the outreach message; ≥89% perceived the amount of information as “about right”; and ≥ 87% completed ≥1 interactive prompt. ConclusionEach intervention component was acceptable to diverse patients and feasible to deliver in a brief, self-directed, online format. InnovationThese novel components target unaddressed barriers to patient engagement in guideline-recommended postpartum diabetes screening and adapt theory-based behavior change techniques for large-scale use.

Gestational diabetes mellitus- can we do better with postpartum diabetes screening?

Patients with gestational diabetes mellitus (GDM) are at risk for developing type-2 DM. Pregnancy and the postpartum period are a window of opportunity for medical intervention which may improve patients’ future health. The standard recommendation following GDM is a 75-gram oral glucose tolerance test (OGTT) 6-12 weeks postpartum. At our hospital, fasting glucose (FG) is obtained from all parturients with GDM 24-48 hours postpartum. We sought to compare the correlation between the postpartum FG value and the results of the OGTT 6-12 weeks postpartum. We reviewed computerized medical records of all patients with a diagnosis of GDM who gave birth at our institution during 2021, and performed an OGTT 6-12 weeks postpartum. We examined the strength of FG as a predictor for an abnormal OGTT. A total of 319 patients met our inclusion criteria. FG was normal in 261 cases (82%), and abnormal in 58 (18%). Most patients had a normal OGTT (229, 72%), however, postpartum OGTT was abnormal in 90 patients (28%). Of them, 84 (93%) were diagnosed with impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), and only 6 patients (7%) were found to have overt DM. A univariate analysis showed a significant correlation between abnormal FG and pathological postpartum OGTT (p=0.001, Pearson’s correlation 0.186). A multivariate analysis also demonstrated FG as a good predictor for IFG or IGT with an adjusted odds ratio (OR) of 1.028 (p=0.048, CI 1.000-1.056). FG as a predictor for overt DM had an adjusted OR of 1.126 (p=0.012, CI 1.026-1.235). Postpartum FG had modest sensitivity for IGT and for DM (31% and 33% respectively). However, the specificity was high for both (87% and 82% respectively), with a negative predictive value (NPV) of 76% for IGF or IGT and 98% for DM. Fasting glucose 24-48 hours postpartum is a good predictor of a pathological OGTT 6-12 weeks postpartum. As the compliance for completing an OGTT is low, we may consider using FG as a tool for predicting future DM.

Society for Maternal-Fetal Medicine Special Statement: Quality metric on the rate of postpartum diabetes screening after pregnancies with gestational diabetes mellitus

As many as 1 in 3 patients with gestational diabetes mellitus have impaired glucose metabolism when screened postpartum. These patients have a 40% to 70% lifetime risk of progression to type 2 diabetes mellitus, but progression can be delayed or prevented by lifestyle interventions or medication. The American College of Obstetricians and Gynecologists and the American Diabetes Association recommend a glucose tolerance test at 4 to 12 weeks postpartum for all patients with gestational diabetes mellitus. Despite these recommendations, postpartum screening rates are typically <50%, representing a major healthcare "quality gap." The Society for Maternal-Fetal Medicine proposes a uniform metric that identifies the percentage of persons with gestational diabetes mellitus who completed a 75-g, 2-hour glucose tolerance test within 12 weeks after delivery. The metric is designed to be measured using diagnosis and procedure codes in payor claims data. Barriers to screening are discussed. Possible uses of the metric for quality improvement projects are outlined. Increasing the rate of postpartum diabetes screening should facilitate timely referral to implement lifestyle modifications, medication, and long-term follow-up. Use of the metric in financial incentive programs is discouraged at this time.

Postpartum uptake of diabetes screening tests in women with gestational diabetes: The PANDORA study.

To determine rates and predictors of postpartum diabetes screening among Aboriginal and/or Torres Strait Islander and non-Indigenous women with gestational diabetes mellitus (GDM). PANDORA is a prospective longitudinal cohort of women recruited in pregnancy. Postpartum diabetes screening rates at 12 weeks (75-g oral glucose tolerance test (OGTT)) and 6, 12 and 18 months (OGTT, glycated haemoglobin [HbA1C ] or fasting plasma glucose) were assessed for women with GDM (n= 712). Associations between antenatal factors and screening with any test (OGTT, HbA1C , fasting plasma glucose) by 6months postpartum were examined using Cox proportional hazards regression. Postpartum screening rates with an OGTT by 12 weeks and 6months postpartum were lower among Aboriginal and/or Torres Strait Islander women than non-Indigenous women (18% vs. 30% at 12 weeks, and 23% vs. 37% at 6months, p < 0.001). Aboriginal and/or Torres Strait Islander women were more likely to have completed a 6-month HbA1C compared to non-Indigenous women (16% vs. 2%, p < 0.001). Screening by 6months postpartum with any test was 41% for Aboriginal and/or Torres Strait Islander women and 45% for non-Indigenous women (p=0.304). Characteristics associated with higher screening rates with any test by 6months postpartum included, insulin use in pregnancy, first pregnancy, not smoking and lower BMI. Given very high rates of type 2 diabetes among Aboriginal and Torres Strait Islander women, early postpartum screening with the most feasible test should be prioritised to detect prediabetes and diabetes for intervention.

Barriers and facilitators to diabetes screening and prevention after a pregnancy complicated by gestational diabetes.

Gestational diabetes mellitus (GDM) is increasing in the United States, with higher rates among minoritized racial and ethnic populations and lower income populations. GDM increases risk for type 2 diabetes (T2DM), and postpartum diabetes screening and prevention are imperative. This qualitative study examines barriers and facilitators to postpartum T2DM screening and prevention among non-privately insured individuals with a history of GDM in a state prior to Medicaid expansion. Thirty-six non-privately insured women with a history of GDM completed semi-structured interviews. Four focus groups and seven interviews were conducted with 30 nurse practitioners, physicians, physician assistants, nurses and registered dietitians from Federally Qualified Health Centers in St. Louis, MO. Interviews and focus groups were audio-recorded and transcribed. Data were analyzed using an integrative thematic analysis informed by the socio-ecological model. Barriers and facilitators to T2DM screening and prevention occur across multiple environments (society, healthcare system, interpersonal, and individual). Societal barriers include insurance issues, unemployment, and lack of transportation, childcare, safe housing, and healthy food access, while facilitators include government sponsored programs and community organizations. Healthcare system barriers include care fragmentation, scheduling policies and time constraints while facilitators include care coordination, pregnancy support groups, and education materials. Interpersonal barriers include negative care experiences, cultural differences, communication challenges, competing priorities, and lack of a social support network, while facilitators include family and friend support and positive care experiences. Individual barriers include health complications and unhealthy food and exercise patterns, while facilitators include child wellbeing, empowered attitudes and healthy food and exercise patterns. The socioecological model highlights the societal and systemic determinants that encompass individual and interpersonal factors affecting postpartum T2DM screening and prevention. This framework can inform multi-level interventions to increase postpartum T2DM screening and prevention in this high-risk population, including policy changes to alleviate higher-level barriers.

Uptake of guideline-recommended postpartum diabetes screening among diverse women with gestational diabetes: associations with patient factors in an integrated health system in USA

331-OR: Gestational Diabetes Knowledge Improves with Interactive Online Training Modules

Background: GDM (gestational diabetes mellitus) increases the lifetime risk of maternal T2DM by 7-fold and increases the risk for maternal and fetal complications. Prenatal education on nutrition, exercise, and T2DM risk among women with GDM increases the likelihood of postpartum diabetes screening. However, access to diabetes education is limited. To address this gap, we created four GDM training modules for nurses and community health workers (CHW) and studied changes in knowledge, attitudes, and intentions before and after training completion. Methods: Online modules (45-60 minutes each with interactive cases and integrated knowledge check questions) were distributed through multiple professional organizations to clinical staff providing care for women with GDM with optional pre- and post-evaluation surveys.Data were not normally distributed. We described baseline population characteristics, GDM knowledge, attitudes, and intentions using median score and interquartile range. We evaluated changes in scores on knowledge, attitude, and intention scales before and after training using non-parametric Wilcoxon matched pair signed rank tests. Results: Seventy-eight individuals completed baseline evaluation (99% female, median age 40, 65% white non-Hispanic; 54% LPN/RN, 22% CHW, 24% other degree) . Nineteen individuals completed all 4 modules and post-training assessments. GDM knowledge improved significantly after training (median pretest - posttest score: 56% to 78%, p&amp;lt;0.001) . The biggest improvement in knowledge was noted in monitoring, medications, and hypoglycemia prevention (51% to 77%, p&amp;lt;0.001) . Intention to recommend diabetes prevention methods also increased after training (median pretest - posttest score: 35.5 to 39.4, max. score 40, p=0.009) . Conclusion: Interactive online modules improved knowledge and intention to recommend diabetes prevention methods. Access to such curricula is critical for improving access to diabetes education among patients. Disclosure P.Krutilova: None. R.C.Williams: None. R.Morey: None. C.Field: None. R.Byrth: None.

Postpartum screening of women with GDM in specialised practices: Data from 12,991 women in the GestDiab register.

Gestational diabetes (GDM) in the short term is associated with various complications during pregnancy; however, in the long run, women have an increased risk of type 2 diabetes mellitus (T2DM). Therefore, short- and long-term follow-up postpartum is recommended. We assessed the proportion of postpartum diabetes screening among 12,991 women with their first GDM-diagnosed pregnancy in the study period in the nationwide German GestDiab register between 2015 and 2017. In addition to assessing prevalence, we assessed if the probability of postpartum screening was associated with maternal characteristics or pregnancy outcomes. In total, 38.2% (95% CI 32.8%-43.7%) of our sample underwent postpartum diabetes screening, irrespective of its timing. Around 50% of women (19.3% of the total sample) undertook the screening in the recommended time frame of 6-12weeks postpartum. We found that age, native language, pre-pregnancy BMI, smoking status, number of previous pregnancies, fasting plasma glucose and HbA1c levels as well as previous pregnancies with GDM and treatment with insulin were associated with participation in the postpartum diabetes screening in our sample. In our study, more than 60% of the women with GDM did not participate in postpartum diabetes screening. This is a missed opportunity in a high-risk population to detect glucose intolerance. Consequently, appropriate interventions to prevent the progression to T2DM cannot be initiated. Further research should investigate barriers and enabling factors and allow developing a multilevel approach for GDM postpartum care.

Barriers to and enablers of type 2 diabetes screening among women with prior gestational diabetes: A systematic review update and qualitative synthesis applying the Theoretical Domains Framework.

Women with prior gestational diabetes have nearly 10 times the risk of developing type 2 diabetes. Postpartum screening for type 2 diabetes is recommended for early diagnosis and management, yet uptake is low. This work updates a previous systematic review and advances it through the application of the Theoretical Domains Framework (TDF) to synthesise personal-level factors impacting type 2 diabetes screening and the Capability, Opportunity, Motivation-Behaviour model (COM-B), to develop messaging recommendations for use in clinical practice and screening promotion interventions. We searched seven academic databases from September 2017 (prior review) to April 2021, reference lists and grey literature. Two reviewers independently screened articles against inclusion criteria (qualitative studies exploring factors impacting postpartum diabetes screening, any language) and extracted data. Using an inductive-deductive model, we coded determinants to the TDF and mapped onto the COM-B model. We identified 38 eligible papers from 34 studies (N=1291 participants). Most (71%) reported sample sizes of N≥16. The ratio of barriers to enablers was three to one. Eight key TDF domains were identified. Evidence-based recommendations include addressing knowledge, risk perception, fear of diabetes diagnosis, low prioritisation of personal health and fatalism. The risk of bias was low and confidence in findings was moderate to high. A limitation was conceptual overlap between TDF domains, which we addressed via the study procedure. The theoretical categorisation of determinants enables the development of messaging and interventions at the personal level, to promote women's uptake of postpartum type 2 diabetes screening.

Postpartum Diabetes Screening: Compliance in the COVID Era

Most women with gestational diabetes (GDM) will not undergo recommended postpartum screening, and it is unknown if COVID has impacted these low rates of follow-up. The objective of this study was to determine the rate at which patients completed their recommended postpartum diabetes screening and compare compliance prior to and during the COVID pandemic.

Understanding Gestational Diabetes, Future Diabetes Risk, and Diabetes Prevention: A Qualitative Study of Patient, Provider, and Staff Perspectives.

Gestational diabetes mellitus (GDM) increases type 2 diabetes risk; however, postpartum diabetes screening rates are low. Using semi-structured interviews and focus groups, this study investigates the understanding of GDM and its relationship to future diabetes risk and diabetes prevention among patients with public or no insurance (n = 36), health care providers (n = 21), and clinic staff (n = 9) from Federally Qualified Health Centers. Five main themes emerged: 1) general understanding of GDM diagnosis with focus on neonatal complications; 2) variable recall of diet, exercise, and weight recommendations; 3) overwhelming medication and self-monitoring routines; 4) short-term focus of type 2 diabetes risk and screening; and 5) limited understanding of all options for diabetes prevention. The results may inform diabetes screening and prevention interventions in primary care settings.

A reminder system for postpartum diabetes screening after gestational diabetes: a randomized clinical trial

Objective To evaluate if a reminder postpartum screening system, providing patients with laboratory requisition on the postpartum ward followed by a telephone reminder one week prior to their 6 weeks appointment, would increase the diabetes mellitus screening rate. Methods Parallel group, open label, multicenter randomized trial. Patients were recruited between July 2015 and March 2016. All women with gestational diabetes mellitus in their index pregnancy with access to a mobile or landline phone were eligible for participation. Gestational diabetes mellitus diagnosis was made with a one-hour 50 g OGTT ≥135 mg/dl, and a subsequent 3 h OGTT with ≥2 values above fasting 95 mg/dl, 1 h 180 mg/dl, 2 h 155 mg/dl, and 3 h 140 mg/dl. Participants were assigned in a 1:1 ratio to “reminder system” (intervention group) or to “routine care (control group).” Those assigned to the reminder system were provided with two reminders. The first was a laboratory requisition slip given to them while on the postpartum ward. The second was a telephone reminder on the fifth week postpartum, consisting of a standardized script to encourage contacted participants to complete the screening test during the sixth week postpartum. The primary outcome was completion of the two-hour 75 g OGTT 6–12 weeks postpartum. Results A total of 75 patients were included in the study. Thirty-eight patients were randomized to the reminder system, and 37 patients were randomized to routine care. A total of 22 women (29.3%) completed the test. In the “reminder” group, 31.6% completed the test, and in the “routine care” group 27% of patients completed the test. This increase in screening uptake in the reminder group was not noted to be statistically significant (p=.8). When evaluating whether perinatal or sociodemographic factors influenced the effect of reminder systems on screening uptake, only insurance type was noted to have a statistically significant influence. Screening uptake was significantly increased in patients with public insurance assigned to “reminder group” (13.5%) compared to those assigned to “routine care” (0%). Of those women who completed the test, seven patients (31.8 %) were diagnosed with prediabetes and none with diabetes. Conclusions Telephone reminders were not found to have a significant impact on increasing postpartum screening for diabetes. The exception was among the publicly insured population. These findings suggest a targeted role for reminder systems, particularly among those with socioeconomic disadvantage.

1279-PUB: Postpartum Screening for Diabetes in Women with a History of Gestational Diabetes

Background: Gestational diabetes (GDM) is glucose intolerance detected for the first time during pregnancy. Women with a history of GDM have a 7-fold higher lifetime risk of developing type 2 diabetes (DMII) compared to women without a history of GDM. Women with a history of GDM should be screened for DMII 6 to 12 weeks postpartum with a 2-hour 75-g oral glucose tolerance test (OGTT) and then again one year after delivery. The long-term goal of this project is to improve screening for DMII in women with a history of GDM. This report establishes the prevalence of GDM, determines the postpartum screening rate, and assesses for barriers to screening at an urban safety-net hospital. This information will be used to design interventions to improve postpartum screening. Methods: We conducted a retrospective chart review of women who had a delivery at Truman Medical Center between January 1, 2017 to December 31, 2019 and had a diagnosis of GDM. Charts were reviewed for demographic data, management of GDM, postpartum appointments, and screening for DMII. Results: There were 9569 deliveries during the three-year period. Of the total deliveries, 537 (5.6%) had a diagnosis of GDM. Of the patients with GDM, 426 (79%) had a postpartum visit scheduled, 354 (66%) attended a 6-week postpartum appointment, 219 (41%) had the recommended test ordered, and 49 (9%) completed the test. The data revealed a significant association with ethnicity, language, insurance type, and site of prenatal care with attending the postpartum appointment (p&amp;lt;0.05) as well as with insurance status on completing the screening test (p&amp;lt;0.05). Conclusion: There is gap in the number of women with GDM and those who are screened for DMII in the postpartum period. There appears to be a disconnect in the ordering of the recommended 2-hour OGTT and the completion of the test. The baseline data supports a multi-prong approach including patient education, system changes, and advocacy for extended insurance benefits to cover screening. Disclosure V. Rakhra: None. M.
