BACKGROUND: Diabetic retinopathy (DR) prevalence is higher in Indigenous Australians than in other Australians and is a major cause of vision loss. Consequently, timely screening and treatment is paramount, and annual eye screening is recommended for Indigenous Australians. AIMS: To assess the prevalence of DR, reduced vision, and DR treatment coverage among Indigenous Australian adults with diabetes attending Top End Indigenous primary care health services. METHODS: A cross-sectional DR screening study conducted from November 2013-December 2015 in two very remote Northern Territory Aboriginal primary healthcare services. RESULTS: In 287 subjects, the prevalence of non-proliferative DR, proliferative DR, and clinically significant diabetic macular oedema (CSMO) was 37.3%, 5.4% and 9.0%, respectively. Treatment coverage for PDR was 60% (of ten patients) and for CSMO was 17% (of 23 patients). Vision data were available from 122 participants at one site. The proportion with normal vision, reduced vision, impaired vision and blindness was 31.1%, 52.5%, 15.6% and 0.8%, respectively. Overall, ungradable monocular image sets (46%) were associated with poorer quality images and missing protocol images (both p

To improve diabetes management in Indigenous Australians using an integrated nurse-led model of diabetes education and eye screening in indigenous primary care and specialist diabetes clinics.A pre-post study.This study will be implemented in indigenous primary care and specialist diabetes clinics in Victoria, Australia. Participants recruited to the study will be existing adult patient with diagnosed diabetes attending study sites. A nurse-credentialled diabetes educator and certified retinal imager will deliver three study components: (a) retinal photography as a diabetic retinopathy screening and patient engagement tool; (b) lifestyle and behaviour surveys, administered at baseline and at the final visit, in 12 months. Findings from the surveys and participants' retinal images will be used to guide; and (c) personalized diabetes education. The primary outcomes are participant adherence to diabetic eye screening recommendations and health service diabetic retinopathy screening coverage. Secondary outcomes are baseline DR prevalence and changes in clinical and lifestyle risk factor levels, diabetes knowledge and satisfaction with diabetes care.Compared with non-indigenous Australians, Indigenous Australians have a high prevalence of diabetic retinopathy and blindness, low adherence to eye screening recommendations and suboptimal health literacy. Nurse-credentialled diabetes educators can be trained to incorporate retinal imaging and eye screening into their clinical practice to give image-based diabetes education to facilitate diabetic retinopathy management.Credentialled nurse diabetes educators who integrate eye screening and diabetes education can facilitate timelier diabetic retinopathy screening, referral pathways and treatment of sight-threatening retinopathy. We believe that this model of integrated diabetes education and eye screening will also improve adherence to eye screening recommendations, population screening coverage, health literacy, risk factor levels and diabetes self-care.ANZCTRN1261800120435.目的: 通过在当地初级护理服务和糖尿病专科诊所使用糖尿病教育与眼病筛查的综合护士主导模式, 促进澳大利亚原住民的糖尿病管理。 设计: 一项前后研究。 方法: 此项研究将在澳大利亚维多利亚州的当地初级护理和糖尿病专科诊所实施。此项研究将招募现有成年糖尿病患者的参与者。一名具备护理资质的糖尿病教育者和经认证的视网膜成像仪将提供三个研究组成部分: (a)作为糖尿病视网膜病变筛查和患者参与工具的视网膜成像仪; (b) 生活方式和行为调查, 在12个月的基线检查和最后就诊时进行。调查结果和参与者的视网膜图像将用于指导; (c) 个性化糖尿病教育。主要结果是参与者遵守糖尿病眼筛查建议和健康服务糖尿病视网膜病变筛查覆盖率。次要结果是基线DR患病率、临床和生活方式危险因素水平的变化、糖尿病知识和对糖尿病护理的满意度。 讨论: 与非澳大利亚原住民相比, 澳大利亚原住民患有糖尿病视网膜病变和失明几率较高, 对眼病筛查建议的依从性较低, 且健康素养较差。具备护理资质的糖尿病教育者可接受培训, 将视网膜成像和眼病筛查纳入其临床实践, 以提供基于图像的糖尿病教育, 促进糖尿病视网膜病变的管理。 影响: 有资质的糖尿病护理教育者结合了眼病筛查和糖尿病教育, 因此可促进及时的糖尿病视网膜病变筛查、转诊途径和威胁视力的视网膜病变的治疗。我们相信, 这种糖尿病教育和眼病筛查的综合模式还将提高对眼病筛查建议、人群筛查覆盖率、健康素养、风险因素水平和糖尿病自我护理的依从性。 临床试验注册: ANZCTRN1261800120435.

To determine eye screening coverage and adherence to national eye screening recommendations of a nurse-led retinal image-based model of diabetes education and eye screening in Indigenous primary care clinics.A pre-post study.During January 2018-March 2020 Indigenous Australians with diabetes at three regional Australian clinics were offered eye screening by a nurse-diabetes educator/retinal imager. At the main site the nurse recruited/scheduled participants, and at satellite sites local clinic staff did so. Visual acuity was tested and digital retinal images acquired and graded. Participants were offered rescreening at or before 12-months based on baseline results.In total 203 adults with diabetes attending Indigenous primary care clinics were screened, with divergent results based on the recruitment methods. At the main clinic 135 of 172 eligible adults (79%) were screened. At the satellite sites, 15 of 85 (18%) and 21 of 77 (27%) diabetes patients were screened. Combined coverage 51%.A credentialed nurse-educator implemented a model of retinal image-based diabetes education, measured eye screening coverage and adherence to national eye screening guidelines, met the 'acceptable 75% eye screening coverage' benchmark and improved patient eye screening guideline adherence at the one site where the nurse-educator had access to patient recruitment and scheduling.This novel nurse-led primary care iDEES model of retinal image-based diabetes education can improve the currently low Indigenous diabetes eye screening coverage in Australia. Importantly, the nurse-managed iDEES model of integrated diabetes care is readily adaptable to other settings and populations where access to and/or uptake of eye care is suboptimal.ANZCTRN1261800120435.

Nationally, Indigenous Australians are more likely to have diabetes and diabetic retinopathy (DR) than non-Indigenous Australians. However, the prevalence of DR and impaired vision in regional primary care settings is unclear.To describe the prevalence and severity of DR and presenting vision level among Indigenous Australian adults with diabetes attending an indigenous primary care clinic in regional Australia.Participants underwent nurse-led retinal imaging and DR screening with offsite retinal grading in the integrated Diabetes Education and Eye Screening (iDEES) project implemented at a regional indigenous primary healthcare setting between January 2018 and March 2020.Of 172 eligible adults, 135 (79%) were recruited and screened for DR and vision level. The median age was 56 (46-67) years, 130 (96%) had type 2 diabetes of median (interquartile range) duration 6 (2-12) years and 48 (36%) were male. Images from 132 (97.8%) participants were gradable. DR was present in 38 (29%) participants: mild non-proliferative in 33 (25%); moderate-severe in three (2.5%); and sight-threatening two (1.5%). Subnormal presenting vision was present in 33%.A nurse-led model of care integrating diabetes eye screening and education at a single visit was successful at recruiting Indigenous Australian adults with diabetes, screening their vision and acquiring a high rate of gradable images. Even for a short duration of known diabetes, DR was present in three out of 10 patients screened.

As diabetes occurs in all ethnicities and regions it is essential that retinopathy screening be widely available. Screening rates are lower in Indigenous than in non-Indigenous Australians. Technological advances and Medicare rebates should facilitate improved outcomes. Use of non-ophthalmic clinicians, (general practitioners, diabetes educators, health-workers and endocrinologists) to supplement coverage by ophthalmologists and optometrists would extend retinopathy screening capacity. Diabetes educators are an integral part of diabetes management. Integrating ocular screening and diabetes education in primary care settings has potential to improve synergistically retinopathy screening coverage, patient self-management, risk factor control, care satisfaction, health economics and sustainability of under-resourced services.
