Exploring the acceptability and experience of receiving diabetes and pregnancy care via telehealth during the COVID-19 pandemic: a qualitative study.

BACKGROUND: The COVID-19 pandemic has significantly impacted the delivery of diabetes in pregnancy care and general maternity care. This study aimed to explore the experiences and acceptability of telehealth use in diabetes in pregnancy care during the COVID-19 pandemic, from the perspectives of pregnant women and their clinicians. The secondary aim was to explore the experiences of pregnant women receiving general maternity care via telehealth during the COVID-19 pandemic. METHODS: In-depth qualitative semi-structured interviews were undertaken and analysed via thematic inductive approaches. The Nonadoption, Abandonment, and Challenges to the Scale-Up, Spread, and Sustainability of Health and Care Technologies Framework (NASSS) was applied. RESULTS: Eigthteen interviews were conducted with culturally and linguistically diverse pregnant women and 4 clinicians (endocrinologists and dietitians). All interviewees were satisfied with telehealth as a positive alternative to face-to-face consultations for diabetes care during the COVID-19 pandemic. Numerous benefits of delivering diabetes care via telehealth were discussed and themes centred around greater access to care, economic benefits and improved safety. Most barriers concerned the adopters (clinicians), yet, feasible and realistic suggestions to overcome barriers were voiced. The scope for technology adaptation and ongoing embedment into routine diabetes care was described. Overall, a hybrid flexible delivery model, predominantly consisting of telephone consultations, with some face-to-face consultations for initial diabetes appointments was recommended for future care. The use of telehealth in replacement of face-to-face appointments for general maternity care was perceived as reducing care quality. CONCLUSION: In this study, telehealth was viewed as acceptable to women and clinicians for diabetes in pregnancy care, supporting the ongoing delivery of a hybrid service model of telehealth and face-to-face care. These findings provide valuable information to improve diabetes in pregnancy services to meet the needs of women during the COVID-19 pandemic and beyond.

Impact of different glycaemic treatment targets on pregnancy outcomes in gestational diabetes.

AIM: With no current randomized trials, we explored the impact of tight compared with standard treatment targets on pregnancy outcomes in gestational diabetes mellitus (GDM). METHODS: This cohort study of singleton births ≥ 28 weeks' gestation was conducted at two major Australian maternity services (2009-2013). Standardized maternal, neonatal and birth outcomes were examined using routine healthcare data and compared for women with GDM at Service One (n = 2885) and Service Two (n = 1887). Services applied different treatment targets: Service One (standard targets, reference group) fasting < 5.5 mmol/l, 2-h postprandial < 7.0 mmol/l; Service Two (tight targets) fasting < 5.0 mmol/l, 2-h postprandial < 6.7 mmol/l. Multivariable regression with propensity score adjustment was used to examine associations between targets and outcomes. RESULTS: GDM prevalence and insulin use were 7.9% and 31% at Service One, and 5.7% and 46% at Service Two. There were no differences in primary outcomes: birthweight > 90th centile [adjusted odds ratio (OR) 1.06, 95% confidence interval (CI) 0.87-1.30] and < 10th centile (OR 0.84, 95% CI 0.70-1.01), or secondary outcomes gestational hypertension, pre-eclampsia, shoulder dystocia or a perinatal composite. Service Two with tight targets had increased induction of labour (OR 3.63, 95% CI 3.17-4.16), elective Caesarean section (OR 1.75, 95% CI 1.37-2.23) and Apgar scores < 7 at 5 min (OR 1.54, 95% CI 1.05-2.25), decreased hypoglycaemia (OR 0.76, 95% CI 0.61-0.94]), jaundice (OR 0.47, 95% CI 0.35-0.63) and respiratory distress (OR 0.68, 95% CI 0.47-0.98). CONCLUSIONS: Tight GDM treatment targets were associated with greater insulin use and no difference in primary birthweight outcomes. The service with tight targets had higher obstetric intervention, lower rates of reported hypoglycaemia, jaundice, respiratory distress and lower Apgar scores. High-quality interventional data are required before tight treatment targets can be implemented.

Large artery biomechanics and diastolic dysfunctionin patients with Type 2 diabetes.

AIMS: To comprehensively characterize large artery biomechanical properties and examine their relationship to cardiac function in patients with Type 2 diabetes mellitus (DM). METHODS: Fifty-five individuals with Type 2 DM were compared with 66 age- and sex-matched healthy control subjects. Arterial biomechanical properties were assessed by systemic arterial compliance (SAC; two-element Windkessel model), carotid-femoral pulse wave velocity (PWVc-f), femoral-dorsalis pedis pulse wave velocity (PWVf-d) and carotid augmentation index. Cardiac structure and function were assessed by echocardiography. RESULTS: Individuals with Type 2 DM had lower SAC and higher PWVc-f when compared with the healthy population. The PWVc-f was significantly lower than the PWVf-d in control individuals, but this difference was not evident in individuals with Type 2 DM due to higher PWVc-f. Augmentation index was similar in both groups, but the time to the first systolic inflection (time to reflection) was shorter in the individuals with Type 2 DM. The individuals with Type 2 DM had a greater prevalence of diastolic abnormalities when compared with the control group. Arterial stiffness indices, including SAC and pulse pressure, correlated with left ventricular filling pressure (defined as peak velocity during early diastolic filling divided by the velocity of movement of the mitral valve annulus in early diastole; r = -0.33 and 0.36 respectively. CONCLUSIONS: Patients with Type 2 DM on standard medication showed preferential stiffening of the large central arteries. However, carotid augmentation index was not different between the two groups and is therefore not a reliable indicator of large artery stiffening in this patient group. Diastolic dysfunction, present in a significant proportion of this population with Type 2 DM, was closely associated with arterial stiffening, suggesting a common aetiology.

The association of smoking status with glycemic control, metabolic profile and diabetic complications- Results of the Australian National Diabetes Audit (ANDA).

BACKGROUND: Tobacco smoking and diabetes mellitus contribute significantly to the overall health burden and mortality of Australians. We aimed to assess the relationship of smoking with glycemic control, metabolic profile and complications in Australian patients living with diabetes. METHODS: We analysed the 2011-2017 biennial Australian National Diabetes Audit cross-sectional data. Patients were classified as current, past or never smokers. Linear (or quantile) and logistic regression models were used to assess for associations. RESULTS: Data from 15,352 patients were analysed, including 72.2% with type 2 diabetes. Current smokers comprised 13.5% of the study population. Current and past smokers had a median HbA1c that was 0.49% and 0.14% higher than never smokers, respectively, as well as higher triglyceride and lower HDL levels (all p values < .0001). Compared to never smokers, current smokers had higher odds of severe hypoglycemia and current and past smokers had higher odds of myocardial infarction, stroke, peripheral vascular disease, lower limb amputation, erectile dysfunction and peripheral neuropathy (all p values ≤.001), with no significant change over time. CONCLUSION: When compared to never smokers, current and past smokers had poorer glycemic and lipid control and higher odds of macrovascular and microvascular complications. Despite this, current smoking remains prevalent among Australians with diabetes.

Diabetic nephropathy: important pathophysiologic mechanisms.

With the global epidemic of type 2 diabetes mellitus, diabetes has become the leading cause of end stage renal failure (ESRF) in most Western countries. Approximately 20-30% of all diabetic subjects will develop evidence of diabetic nephropathy, which represents a continuum from microalbuminuria, to overt nephropathy or macroalbuminuria, and finally ESRF. While there have been significant breakthroughs in the last decade with regards to the prevention and treatment of diabetic kidney disease, in particular blockade of the renin angiotensin system, there is a vital need to identify and target novel pathophysiologic pathways such as advanced glycation which appear to be centrally involved in diabetic renal disease in order to reduce the rising burden of this disease.
