Diabetic retinopathy (DR) in pregnancy can cause blindness. National guidelines recommend at least one eye examination in early pregnancy, then ideally 3-monthly, through to the postpartum for pregnant women with pregestational diabetes. Here we examined adherence rates, barriers and enablers to recommended DR screening guidelines.

Cross-sectional survey study, as part of a larger prospective cohort study.

Participants were recruited from two tertiary maternity hospitals in Melbourne, Australia.

Of the 173 pregnant women with type 1 (T1D) or type 2 diabetes (T2D) in the main cohort study, with an additional four who participated solely in this survey study, 130 (74.3%) completed the survey.

This study calculated rates of adherence to guideline-recommended DR screening schedules and collected data on the enablers and barriers to attendance using a modified Compliance with Annual Diabetic Eye Exams Survey. Each of the 5-point Likert-scale survey items was compared between adherent and non-adherent participants using the Wilcoxon rank-sum test and logistic regression models were constructed to quantify associations as ORs.

A retinal assessment was undertaken at least once during pregnancy in 86.3% of participants, but only 40.9% attended during their first trimester and only 21.2% attended the recommended number of examinations. Competing priorities were the main barriers to adherence, with eye examinations ranked as the fourth priority (IQR 4th–5th) among other health appointments during pregnancy. Meanwhile, knowledge of the benefits of eye screening examinations, eye-check reminders and support from relatives was identified as enablers.

Despite the risk of worsening DR during pregnancy, less than half of the participants adhered to recommended screening guidelines, suggesting that eye health is not a priority. Proactive measures to integrate care are needed to prevent visual loss in this growing population.

Although as many as 92% of survivors of physical intimate partner violence (IPV) report impacts to the head and/or non-fatal strangulation (NFS) that raise clinical suspicion of brain injury (BI), there are no evidence-based methods to document and characterise BI in this vulnerable population, limited clinical practice guidelines and insufficient understanding about long-term risks for conditions including Alzheimer’s Disease and Related Dementias (ADRD). This leaves most survivors of IPV-caused BI (IPV-BI), overwhelmingly women, without adequate access to medical care and support, safe housing, back-to-school/work accommodations or follow-up care for long-term neurocognitive health. Although traumatic brain injury (TBI) is an established ADRD risk factor, little is known about the attributable risk of ADRD due to IPV-BI, particularly in women.

Our overarching objectives are to (1) use plasma biomarkers as novel tools to assist clinicians to improve diagnosis of IPV-BI at the acute, subacute and chronic stages in a manner sensitive to the needs of this vulnerable population and (2) raise awareness of the importance of considering IPV-BI as a potential ADRD risk factor. A prospective observational study funded by the US Department of Defense (HT9425-24-1-0462), Brain Canada (6200) and the Canadian Institutes of Health Research (523320-NWT-CAAA-37499) leverages collaborative research at multiple clinical sites in British Columbia to maximise equity, diversity and inclusion among participants, with a target enrolment of n=600 participants.

The Advocates, Academics, Survivors and Clinicians to END Intimate Partner Violence Biomarkers study, which is predicated on pre-specified research questions, represents one of the most significant community-based studies on plasma biomarkers affected by an IPV-BI incident. Of particular significance is the fact our study uses robust biomarker approaches being applied in the TBI and ADRD fields to determine how the biomarker profile after IPV-BI compares to typical TBI and the early stage of neurodegenerative disorders.

This study was approved by the University of British Columbia Clinical Research Ethics Board (H24-01990, H22-02241 and H16-02792) and the Island Health Research Ethics Board (H22-03510). Upon publication of primary papers, de-identified data and biospecimens will be made widely available, including the US Federal Interagency Traumatic Brain Injury Research (FITBIR) federated database. Our data and integrated knowledge translation activities with persons with lived experience of IPV-BI and those working in the healthcare sector will be synthesised into co-designed and implemented knowledge tools to improve outcomes for survivors of IPV-BI.

To assess the impact of opening a large community-based asynchronous review ophthalmic clinic on attendance delays among patients with stable chronic eye disease attending a London teaching eye hospital network.

Interrupted time-series analysis of routine electronic health records of appointment attendances.

A large eye hospital network with facilities across London, UK, between June 2018 and April 2023.

We analysed 69 257 attendances from 39 357 patients, with glaucoma and medical retina accounting for 62% (n=42 982) and 38% (n=26 275) of visits, respectively. Patients over 65 made up 54% (n=37 824) of attendances, while 53% (n=37 014) were from the more deprived half of the population, and 51% (n=35 048) were males.

An asynchronous review clinic opened in a shopping centre in London, in autumn 2021, following the COVID-19 lockdown in spring 2020.

Average attendance delays (days), calculated as the difference between follow-up attendance date and the latest clinically appropriate date determined at the preceding attendance.

Pre-COVID-19, attendance delays for chronic eye disease monitoring were increasing by 0.9 days per week (95% CI, 0.8 to 0.9) on average, worsening to 2.0 days per week (95% CI, 2.0 to 2.0) after the first COVID-19 national lockdown, mid-March 2020. Opening the asynchronous review clinic increased appointment capacity, with delays decreasing on average by 8.1 days per week (95% CI, 8.1 to 8.2) shortly after opening. The rate of decrease slowed to 0.3 days per week (95% CI, 0.3 to 0.3) after 5 months. We found no significant differences in average attendance delays by age, gender or level of deprivation.

The asynchronous review clinic significantly reduced attendance delays across the hospital network, addressing pre-existing backlog for stable chronic eye diseases. The reduction appeared to be maintained after the initial backlog had been cleared.
