ABSTRACT
BACKGROUND: Removal of diabetes devices, including insulin pumps and continuous glucose monitoring (CGM), is a common practice due to hospital policies, interference with imaging studies, medications, and surgical interventions. Furthermore, these devices are inherently prone to malfunction, adhesive failure, and issues with insertion that can lead to a reduction in wear time. Prescription and dispensing practices provide an exact number of sensors per month without redundancy to account for the realities of daily CGM use. METHODS: A RedCap survey was completed by adult patients with type 1 or type 2 diabetes (T1D or T2D) who utilize CGM followed in the Diabetes Center at Washington University in St Louis. RESULTS: Of 384 surveys sent, 99 were completed. Participants had a mean age of 54 years, T1D 69%, female 70%, White 96%, non-Hispanic 96%, and a mean duration of diabetes mellitus (DM) 28 years. Of the cohort, 100% used CGM (80.2% Dexcom, 13.5% Freestyle Libre, 6.3% Medtronic), 61% insulin pump, and 41% Hybrid closed-loop (HCL) systems. CGM-related disruption events included device malfunction (in 85.4% of participants), insertion problems (63.5%), and falling off (61.4%). Medical care-related disruption occurred most frequently in the setting of imaging (41.7%), followed by surgery/procedures (11.7%) and hospitalization (4.4%). Adverse glycemic events attributed to CGM disruption, including hyperglycemia and hypoglycemia, occurred ≥4 times in 36.5% and 12.4% of the cohort, respectively. CONCLUSIONS: Disruption in CGM use is common. Lack of redundancy of CGM supplies contributes to care disruption and adverse glycemic events.
ABSTRACT
Background: The risk of developing type 2 diabetes mellitus (T2DM) is up to 50% among women with gestational diabetes mellitus (GDM). GDM also increases risks for pre-term birth, macrosomia, fetal hypoglycemia, and C-section delivery. Education for expectant mothers with GDM about nutrition, exercise, and the risks of developing T2DM after delivery enhances the probability of postpartum diabetes screening. However, the availability of diabetes education is limited. To bridge this gap, our team developed four training modules on GDM tailored for nurses and community health workers. This pilot study assesses changes in knowledge, self-efficacy for providing diabetes education, attitudes, and intentions to recommend diabetes prevention before and after training completion. Methods: These interactive online modules, each lasting 45-60 minutes and featuring engaging case studies and integrated knowledge assessment questions, were disseminated through various professional organizations to clinical staff providing care for women with GDM. Optional pre- and post-training surveys were conducted to gauge the effectiveness of the modules. Collected data did not follow a normal distribution pattern. We provided an overview of the baseline characteristics of the population, self-efficacy, attitudes, intentions, and GDM knowledge by calculating the median scores and interquartile ranges. We assessed the changes in scores on self-efficacy, attitudes, intentions, and GDM knowledge before and after training using non-parametric Wilcoxon matched-pair signed rank tests. Results: Eighty-two individuals completed baseline evaluation and 20 individuals accessed all modules and completed post-training assessments. Among those completing the training, improvement was noted in GDM knowledge [56.5% (16.0) v. 78.3% (22.0), p < 0.001], Self-efficacy for providing diabetes education [6.60 (2.73) v. 9.33 (0.87), p < 0.001], attitudes toward the value of tight control [4.07 (0.79) v. 4.43 (0.86), p = 0.003], and intentions to recommend diabetes prevention measures [4.81 (0.63) v. 5.00 (0.00), p = 0.009)]. Conclusions: Completion of our interactive online modules improved knowledge, intention to recommend diabetes prevention methods, self-efficacy to provide diabetes education, and attitudes toward the value of tight control among individuals caring for women with GDM. Enhanced accessibility to such curricula is crucial to improve access to diabetes education. Trial registration: This study was registered at clinicaltrials.gov, identifier: NCT04474795.
