Uptake Of Diabetic Retinopathy Screening Research Articles

Uptake of diabetic retinopathy screening at a secondary level facility in Malawi.

Diabetic retinopathy (DR) is a common microvascular complication of long-standing diabetes mellitus (DM). DR screening is a cost-effective intervention for preventing blindness from DR. We conducted a cross-sectional study to investigate the uptake and the predictors of uptake of annual DR screening in an opportunistic DR screening programme at a secondary-level diabetes clinic in Southern Malawi. Consecutive patients were interviewed using a structured questionnaire to record their demographic characteristics, medical details and data regarding; the frequency of clinic visits, knowledge of existence of DR screening services and a history of referral for DR screening in the prior one year. Univariate binary logistic regression was used to investigate predictors of DR screening uptake over the prior one year. Explanatory variables that had a P-value of < 0.1 were included into a multivariate logistic regression model. All variables that had a p-value of <0.05 were considered to be statistically significant. We recruited 230 participants over three months with a median age of 52.5 years (IQR 18-84) and a median duration of diabetes of 4 years (IQR 1-7). The average interval of clinic visits was 1.2 months (SD ± 0.43) and only 59.1% (n = 139) of the participants were aware of the existence of diabetic retinopathy screening services at the facility. The uptake for DR screening over one year was 20% (n = 46). The strongest predictors of uptake on univariate analysis were awareness of the existence of DR screening services (OR 10.05, P <0.001) and a history of being referred for DR screening (OR 9.02, P <0.001) and these remained significant on multivariable analysis. Interventions to improve uptake for DR screening should promote referral of patients for DR screening and strengthen knowledge about the need and availability of DR screening services.

Predictors of attendance at diabetic retinopathy screening among people with type 2 diabetes: Secondary analysis of data from primary care

AimsTo estimate the uptake of diabetic retinopathy screening among adults with type 2 diabetes and to identify and compare factors associated with attendance at the national diabetic retinal screening programme, and other screening services provided by ophthalmic surgeons, community ophthalmologists and optometrists. MethodsAn observational retrospective cohort study was carried out using data from the 2016 audit of care delivered by general practices (n = 30) enrolled in a structured diabetes care initiative.Attendance at any screening in the previous 12 months, and attendance across different types of service (national programme and other screening services) was calculated. Logistic regression was performed to examine predictors associated with (1) attendance at any screening and (2) attendance at the national programme (RetinaScreen). Sociodemographic, clinical, and lifestyle factors were examined as predictors. ResultsData were available for 1106 people with type 2 diabetes aged ≥18 years.Overall, 863 (78%) of patients had a record of screening attendance in the previous 12 months. Of those screened, 494 (57.2%) attended RetinaScreen only, 258 (28.7%) attended other screening services only, and 111 (12.9%) attended both services.Statistically significant predictors of attendance at any screening were tablet/injectable controlled diabetes, attendance at a diabetes nurse specialist (DNS) in the past 12 months and a blood glucose level which was not on target (HbA1c >7.0% or >53 mmol/mol). In addition to these factors, when examining predictors of attendance at the national screening programme specifically, females were less likely to attend. ConclusionsMost patients managed in a structured diabetes care programme in primary care attended screening. Those with on target blood glucose control, those who were on oral or injectable medication or had been seen by a DNS were more likely to attend for annual screening. Of those who attended screening, almost one-third attended other screening services and so were not availing of the national programme, which is free, quality assured and has an integrated treatment arm.

A micro costing analysis of the development of a primary care intervention to improve the uptake of diabetic retinopathy screening

BackgroundThe application of economic analysis within implementation science is still developing and the cost of intervention development, which differs markedly from the costs of initial implementation and maintenance, is often overlooked. Our aim was to retrospectively cost the development of a multifaceted intervention in primary care to improve attendance at diabetic retinopathy screening.MethodsA retrospective micro costing of developing the intervention from the research funder perspective was conducted. It was based on a systematic intervention development process involving analysis of existing audit data and interviews with patients and healthcare professionals (HCPs), conducting consensus meetings with patients and HCPs, and using these data together with a rapid review of the effectiveness of interventions, to inform the final intervention. Both direct (non-personnel, e.g. travel, stationary, room hire) and indirect (personnel) costs were included. Data sources included researcher time logs, payroll data, salary scales, an online financial management system, invoices and purchase orders. Personnel involved in the intervention development were consulted to determine the activities they conducted and the duration of their involvement. Sensitivity and scenario analyses were conducted to estimate uncertainty around parameters and scope.ResultsThe total cost of intervention development (July 2014–January 2019) was €40,485 of which 78% were indirect (personnel) costs (€31,451). In total, personnel contributed 1368 h to intervention development. Highest cost activities were the patient interviews, and consensus process, contributing 23% and 34% of the total cost. Varying estimated time spent on intervention development activities by + 10% increased total intervention development cost by 6% to €42,982.ConclusionsOur results highlight that intervention development requires a significant amount of human capital input, combining research experience, patient and public experience, and expert knowledge in relevant fields. The time committed to intervention development is critical but has a significant opportunity cost. With limited resources for research on developing and implementing interventions, capturing intervention development costs and incorporating them as part of assessment of cost-effective interventions, could inform research priority and resource allocation decisions.

Uptake of Screening for Diabetic Retinopathy and Associated Factors among Adults with Diabetes Mellitus Aged 18-65 Years: A Descriptive Cross Sectional Study

The prevalence of diabetes in Zimbabwe has increased significantly in the past three decades posing serious challenges to the provision of care and prevention of disabling co-morbidities in an already disadvantaged healthcare setting. Studies conducted in Zimbabwe have reported prevalence of 16% to 38%. Diabetic retinopathy, a major complication of diabetes, is a leading cause of blindness globally and of an estimated 285 million people with diabetes worldwide approximately 33.3% have signs of diabetic retinopathy and of these a further 33.3% have vision threatening diabetic retinopathy. The purpose of this study is to examine uptake of screening for diabetic retinopathy and associated factors among adults aged 18-65 years with diabetes at Parirenyatwa Group of Hospitals. This was a cross sectional analytical study on a random sample of 83 adults aged 18-65 years with diabetes mellitus. The study was conducted according to the requirements of the Declaration of Helsinki. A structured questionnaire was used to collect data in strict privacy and confidentiality. Uptake of screening was 53%. The chi-square test was done to analyse demographic factors associated with uptake of screening. Male gender and being married were significantly associated with higher uptake of screening (p=0.029 and p=0.037 respectively). Logistic regression was done to determine predictors of uptake of screening services for diabetic retinopathy. On logistic regression, gender (OR=0.241, 95% CI [0.079 – 0.735]) and misinformation (OR=0.280, 95% CI [0.081 – 0.974]) were significant predictors of uptake of screening. Uptake of diabetic retinopathy screening was sub-optimal. Gender and misinformation were significant barriers to uptake of screening. There is need to address barriers to uptake of retinopathy screening to promote timely identification and management of complications in people with diabetes mellitus.

Development of an intervention to facilitate implementation and uptake of diabetic retinopathy screening

Background‘Implementation interventions’ refer to methods used to enhance the adoption and implementation of clinical interventions such as diabetic retinopathy screening (DRS). DRS is effective, yet uptake is often suboptimal. Despite most routine management taking place in primary care and the central role of health care professionals (HCP) in referring to DRS, few interventions have been developed for primary care. We aimed to develop a multifaceted intervention targeting both professionals and patients to improve DRS uptake as an example of a systematic development process combining theory, stakeholder involvement, and evidence.MethodsFirst, we identified target behaviours through an audit in primary care of screening attendance. Second, we interviewed patients (n = 47) and HCP (n = 30), to identify determinants of uptake using the Theoretical Domains Framework, mapping these to behaviour change techniques (BCTs) to develop intervention content. Thirdly, we conducted semi-structured consensus groups with stakeholders, specifically users of the intervention, i.e. patients (n = 15) and HCPs (n = 16), regarding the feasibility, acceptability, and local relevance of selected BCTs and potential delivery modes. We consulted representatives from the national DRS programme to check intervention ‘fit’ with existing processes. We applied the APEASE criteria (affordability, practicability, effectiveness, acceptability, side effects, and equity) to select the final intervention components, drawing on findings from the previous steps, and a rapid evidence review of operationalised BCT effectiveness.ResultsWe identified potentially modifiable target behaviours at the patient (consent, attendance) and professional (registration) level. Patient barriers to consent/attendance included confusion between screening and routine eye checks, and fear of a negative result. Enablers included a recommendation from friends/family or professionals and recognising screening importance. Professional barriers to registration included the time to register patients and a lack of readily available information on uptake in their local area/practice. Most operationalised BCTs were acceptable to patients and HCPs while the response to feasibility varied. After considering APEASE, the core intervention, incorporating a range of BCTs, involved audit/feedback, electronic prompts targeting professionals, HCP-endorsed reminders (face-to-face, by phone and letter), and an information leaflet for patients.ConclusionsUsing the example of an intervention to improve DRS uptake, this study illustrates an approach to integrate theory with user involvement. This process highlighted tensions between theory-informed and stakeholder suggestions, and the need to apply the Theoretical Domains Framework (TDF)/BCT structure flexibly. The final intervention draws on the trusted professional-patient relationship, leveraging existing services to enhance implementation of the DRS programme. Intervention feasibility in primary care will be evaluated in a randomised cluster pilot trial.

Diabetic retinopathy screening in persons with mental illness: a literature review.

People living with severe mental illness (SMI) have an increased risk of developing diabetes and are less likely to spontaneously report physical health concerns; they may therefore derive greater benefit from attending screening to prevent diabetic retinopathy.We conducted a literature review to consider the uptake of diabetic retinopathy screening (DRS) in people with mental illness.People with a diagnosis of SMI and those with self-reported mental ill-health have reduced attendance at DRS, within the context of poorer compliance with general diabetic care. Anxiety and depression were noted as barriers in attending DRS.People living with SMI require additional support to benefit from preventative health programmes such as DRS. Further research could support a better understanding of barriers to attendance, allowing effective support systems to be developed.

Association between community outpatient clinic care accessibility and the uptake of diabetic retinopathy screening: A multi-level analysis

AimsTo investigate the uptake rate variance of fundus examination for diabetes-related complications among demographically and geographically diverse communities and examine determinants that influence this rate focusing on outpatient eye care clinic accessibility at community level. MethodsData of 20,904 participants with diabetes from 228 communities in 2015 were collected from the nationwide Community Health Survey and Statistics Korea. Outpatient eye care clinic accessibility was measured by the number of eye clinics per 1000 population. Multilevel analysis was conducted to assess the fundus examination uptake rate across communities and examine the association of individual- and community-level determinants with this rate. ResultsThe uptake rate among patients with diabetes was 34.8% and varied across communities. At the individual level, determinants related to knowledge and awareness were significantly positively associated with fundus examination uptake. At the community level, increases in the number of eye clinics were associated with significant increases in fundus examination uptake (OR 1.21; 95% CI 1.03–1.43). ConclusionsBased on the result that outpatient eye care clinic accessibility was significantly associated with the uptake rate across communities, improving accessibility may be an important factor and should be considered when developing interventions for promoting regular diabetic retinopathy screening. This will lead to earlier detection of complications and minimize diabetes-related visual impairment.

Evaluation of whether health education using video technology increases the uptake of screening for diabetic retinopathy among individuals with diabetes in a slum population in Hyderabad.

Purpose:A community-based intervention to compare the effectiveness of pamphlets and videos as education material to promote diabetic retinopathy (DR) screening in urban slums of Hyderabad and to identify barriers/facilitators for compliance with DR screening.Methods:A cross-sectional survey among people with diabetes (sample of 267) was followed by a health education intervention where patients were allocated into two groups (121 received pamphlets and 102 attended video sessions). The effectiveness of the intervention was assessed based on the uptake of DR screening. The facilitating factors and barriers to DR screening were explored through semi-structured interviews and focus group discussions with participants and health workers. Data analysis included Chi-square test for quantitative data and thematic analysis for qualitative data.Results:Among the 235 people in the health education intervention study, 131 (55.7%) received the pamphlet and 104 (44.3%) watched the educational videos. The uptake of DR screening within 2 months was higher in the group shown the educational video than who received the pamphlet (32.7% vs 11.45%; P < 0.05). Absence of an accompanying person and good vision were barriers that prevented patients from screening. Realization of consequences of DR and proximity of the screening facility were identified as motivators. The major results we found in the initial survey of 267 people were that 74.5% had never had HbA1c test and locals underwent health check-ups more regularly than migrants (62.2% versus 34%; P < 0.05).Conclusion:Educational videos led to greater behavior change than pamphlets in motivating diabetics for DR screening.

Diabetic retinopathy screening uptake after health education with or without retinal imaging within the facility in two AYUSH hospitals in Hyderabad, India: A nonrandomized pilot study

Purpose:In India, people with diabetes (PwDM) often seek care in the government-approved alternative medicine system, AYUSH (Ayurveda, Yoga and naturopathy, Unani, Siddha and Homeopathy). The purpose of this pilot study was to assess whether health education plus retinal imaging for diabetic retinopathy (DR) within an AYUSH hospital increased the uptake of screening for DR compared with health education and referral.Methods:The study was a nonrandomized pilot conducted in two AYUSH hospitals. Both hospitals received intervention on educating the AYUSH practitioners about DR screening and distributing health education materials to diabetic patients. In one hospital in addition to education, retinal imaging by a trained technician with remote grading by an ophthalmologist was provided, while in another hospital PwDM were referred to nearby eye hospitals for screening. The uptake of screening was assessed through registers and phone calls.Results:At baseline, only 10.7% of 178 PwDM were aware of DR and only 8% had undergone DR screening. After the intervention, in the hospital where screening was provided, all (100%) eligible patients (101) underwent digital imaging, whereas in the other hospital only 25% of 77 eligible patients underwent screening in eye hospitals (P < 0.001).Conclusion:AYUSH hospitals could provide a feasible and acceptable location for providing DR screening services. Further studies are required to assess scale-up of such intervention.

Effect of health education and screening location on compliance with diabetic retinopathy screening in a rural population in Maharashtra.

Purpose:To compare the acceptance of diabetic retinopathy (DR) screening by the proximity of care and health education in rural Maharashtra.Methods:Study was done in the public health facilities in four blocks (in two blocks at community health center (CHC) level and in other two blocks at primary health center (PHC) level with the provision of transport from villages to PHCs) over 3 months. Health education was not imparted in one block in each segment. Health education consisted of imparting knowledge on diabetes mellitus (DM) and DR by trained village-level workers. The screening was done using non-mydriatic fundus camera and teleophthalmology supported remote grading of DR.Results:In the study period, 1,472 people with known diabetes were screened in four blocks and 86.6% (n = 1275) gradable images were obtained from them. 9.9% (n = 126) were detected having DR and 1.9% (n = 24) having sight-threatening DR (STDR). More people accepted screening closer to their residence at the PHC than CHC (24.4% vs 11.4%; P < 0.001). Health education improved the screening uptake significantly (14.4% vs 18.7%; P < 0.01) irrespective of the place of screening—at CHC, 9.5% without health education vs 13.1% with health education; at PHC, 20.1% without health education versus 31.6% with health education.Conclusion:Conducting DR screening closer to the place of living at PHCs with the provision of transport and health education was more effective for an increase in the uptake of DR screening by people with known diabetes in rural Maharashtra.

Understanding the uptake of a national retinopathy screening programme: An audit of people with diabetes in two large primary care centres

Background: Diabetic retinopathy (DR) is estimated to affect 25–26% of the Irish population with diabetes and is one of the leading causes of blindness among working-age adults. Regular diabetic retinopathy screening (DRS) can reduce the risk of sight loss. In 2013, the new national screening programme (RetinaScreen) was introduced in Ireland. Maximising DRS uptake (consent to participate in the programme and attendance once invited) is a priority, therefore it is important to identify characteristics which determine DRS uptake among those with diabetes in Ireland. We report uptake in an Irish primary care population during the initial phase of implementation of RetinaScreen and investigate factors which predict consenting to participate in the programme. Methods: In two primary care practices, data were extracted from records of people with diabetes (type 1 and type 2) aged ≥18 years who were eligible to participate in RetinaScreen between November 2013 and August 2015. Records were checked for a RetinaScreen letter. RetinaScreen were contacted to establish the status of those without a letter on file. Multivariable Poisson regression was used to examine associations between socio-demographic variables and consenting. Adjusted incident rate ratios (IRR) with 95% CI were generated as a measure of association. Results: Of 722 people with diabetes, one fifth (n=141) were not registered with RetinaScreen. Of 582 who were registered, 63% (n=365) had participated in screening. Most people who consented subsequently attended (n=365/382, 96%). People who had attended another retinopathy screening service were less likely to consent (IRR 0.65 [95%CI 0.5-0.8]; p&lt;0.001). Other predictors were not significantly associated with consent. Conclusions: Over one third of eligible participants in RetinaScreen had not consented. Research is needed to understand barriers and enablers of DRS uptake in the Irish context. Implementing strategies to improve DRS uptake, barriers to consent in particular, should be a priority.

Understanding the uptake of a national retinopathy screening programme: An audit of patients with diabetes in two large primary care centres.

Background: Diabetic retinopathy (DR) affects 8.2% of the Irish population with type 2 diabetes over 50 years and is one of the leading causes of blindness among working-age adults.

Process of adaptation, development and assessment of acceptability of a health educational intervention to improve referral uptake by people with diabetes in Sri Lanka

BackgroundOne major barrier to uptake of diabetic retinopathy (DR) services is lack of knowledge and awareness of DR among the people with diabetes (PwDM). Targeted health education (HE) can be a key element in improving the uptake of eye care services. Such interventions are lacking in Sri Lanka.MethodsA local context specific HE intervention (HEI) was developed by adopting available resources and incorporating views from PwDM and key stakeholders. Four sessions of participatory workshops with PwDM (20 Sinhala and 13 Tamil speaking) and two stage 12 stakeholder interviews were conducted to both develop and pre-test the material. The products were a video and a leaflet, delivered at a medical clinic to a sample of 45 PwDM identified as having DR. Semi-structured interviews were conducted after 4 weeks, to evaluate the acceptability and comprehension of the HEI. Additionally, nine interviews were conducted with clinical providers to explore process issues related to delivery of the HEI. Data analysis was conducted using thematic analysis.ResultsThe lack of knowledge and awareness on DR, and of the importance of regular DR screening and follow up, combined with poor information on referral pathways were key elements identified from the workshops with PwDM. The stakeholders prioritised the importance of using simple language, and the need for emphasis on improving understanding about the asymptomatic phase of DR. The overall acceptability of the HEI material was satisfactory, although there was some difficulty with interpretation of medical images. Overall, although PwDM liked the ideas of the video, the leaflet was seen as a more practical option, given the busy clinic environment. The key issue was both formats required interaction with the provider, in order to support understanding of the messages.ConclusionsThe process of adapting HE material is not simply translation into the appropriate language. Instead, a tailored approach in a country, context and particular health services setting is needed. This study illustrates the value of using a participatory approach and involving PwDM and stakeholders in the adaptation and pilot testing of a HEI to improve uptake of screening for DR in the context of Sri Lanka.

A qualitative study on barriers and enablers to uptake of diabetic retinopathy screening by people with diabetes in the Western Province of Sri Lanka

BackgroundBlindness and visual impairment from diabetic retinopathy (DR) are avoidable through early detection and timely treatment. The Western Province of Sri Lanka has the highest prevalence of diabetes mellitus (DM) (18.6%) in the country. A situational analysis identified a significant gap in DR screening services (DRSS) uptake in this region. Barriers that hinder people with DM (PwDM) from attending DRSS are poorly understood. The purpose of this study is to understand the factors which influence the uptake of DRSS and follow-up to inform health promotion strategies and improve the uptake of these services.MethodsEleven focus group discussions (FGDs) were conducted with PwDM who presented to medical, general eye and vitreoretinal services in three public sector institutions (two tertiary and one secondary level) in the Western Province between October 2016 and March 2017. We enrolled six groups (four Sinhala speaking, two Tamil) of women and five groups (three Sinhala and two Tamil) of men representing ethnicity and gender. We performed a thematic analysis and described the main themes and subthemes using the socio-ecological model as a framework.ResultsWe identified lack of knowledge of both the condition and the need for screening as key barriers to access DRSS. Socio-cultural factors in the family environment, economic reasons and institutional factors were also important barriers. Additional reasons include long waiting time at eye clinics and poor referrals exacerbated by the lack of a systematic DRSS. In addition, attitudes to DRSS such as fear of discomfort from the procedure and the need for accompaniment following mydriasis were also deterrents to follow-up screening.ConclusionThis study has shown that there are inter-related user, family, and institutional factors which affect the uptake of DRSS. Understanding how DR is conceptualised by PwDM in this region is essential to refine strategies to improve access to DRSS. Strategies to improve knowledge need to be more culturally acceptable and relevant to PwDM and their families, with increased availability of DRSS at convenient locations may increase timely uptake of screening.

Influence of primary care practices on patients' uptake of diabetic retinopathy screening: a qualitative case study.

BackgroundThe NHS Diabetic Eye Screening Programme aims to reduce the risk of sight loss among people with diabetes in England by enabling prompt diagnosis of sight-threatening retinopathy. However, the rate of screening uptake between practices can vary from 55% to 95%. Existing research focuses on the impact of patient demographics but little is known about GP practice-related factors that can make a difference.AimTo identify factors contributing to high or low patient uptake of retinopathy screening.Design and settingQualitative case-based study; nine purposively selected GP practices (deprived/affluent; high/low screening uptake) in three retinopathy screening programme areas.MethodsSemi-structured interviews were conducted with patients, primary care professionals, and screeners. A comparative case-based analysis was carried out to identify factors related to high or low screening uptake.ResultsEight possible factors that influenced uptake were identified. Five modifiable factors related to service and staff interactions: communication with screening services; contacting patients; integration of screening with other care; focus on the newly diagnosed; and perception of non-attenders. Three factors were non-modifiable challenges related to practice location: level of deprivation; diversity of ethnicities and languages; and transport and access. All practices adopted strategies to improve uptake, but the presence of two or more major barriers made it very hard for practices to achieve higher uptake levels.ConclusionsA range of service-level opportunities to improve screening attendance were identified that are available to practices and screening teams. More research is needed into the complex interfaces of care that make up retinopathy screening.

Cluster randomised controlled trial evaluation of a Link Worker–delivered intervention to improve uptake of diabetic retinopathy screening in a South Asian population

Attendance at diabetic retinopathy screening in minority ethnic groups, including the South Asian population, is known to be poor. We describe a cluster randomised controlled trial conducted in 10 general practitioner (GP) surgeries in Coventry, UK, during 2007 which aimed to evaluate the use of a Link Worker-delivered intervention to improve attendance. The intervention consisted of a simple telephone reminder with the main outcome measure being attendance at diabetic retinopathy screening. We found a statistically significant difference between mean attendance proportions for intervention (0.89) and control (0.74) practices: difference (95% confidence interval (CI)) 0.15 (0.04-0.27), t = 3.03, p = 0.0162; this difference remained significant when adjusted for previous year's proportions. In this proof-of-concept study, in inner city Coventry, we demonstrated increased attendance at diabetic retinopathy screening by use of a simple Link Worker-implemented telephone call intervention. The use of Link Worker phone calls may be a useful tool to increase attendance for diabetic retinopathy screening in a group with high did-not-attend (DNA) rates and a high prevalence of diabetic retinopathy and visual impairment.

Equity of uptake of a diabetic retinopathy screening programme in a geographically and socio-economically diverse population

At the time of undertaking the audit, the uptake of diabetic retinopathy screening in Derbyshire was 73%, below the national standard of 80%. To assess equity of access to diabetic retinopathy screening in a geographically and ethnically diverse population and determine predictors for poor uptake that will inform service improvements. Mixed methods health equity audit. Postal questionnaires were issued to 1000 people invited for diabetic retinopathy screening in May 2010 and telephone interviews were conducted with subsample of 32 people who had not made a screening appointment. Routine data from the screening programme was used to identify characteristics of people who did not respond to screening invitation. The adjusted odds ratios (OR) and 95% confidence intervals (95% CI) using multivariate methods were calculated in this study. The response rate to the postal questionnaire was 43%. Of these, 28% of respondents did not recall discussing the importance of diabetic retinopathy screening with their primary care team and 11% of people did not understand the term 'diabetic retinopathy'. Non-uptake of screening was associated with deprivation (OR 1.19, 95% CI 1.10-1.29 for those living in the most deprived areas compared to the least deprived) and young people were over three times more likely not to participate than older people (OR 3.13, 95% CI 2.70-3.64 for men under 40 compared to men over 80 and OR 3.03, 95% CI 1.54-5.98 for people with type 1 diabetes under 40 compared to those over 80). Ensuring that primary care and other health care and third sector organisations convey the importance of diabetic retinopathy screening with patients and improving patients' understanding of the screening programme may improve uptake. Interventions to increase uptake should be targeted to younger people, especially those with type 1 diabetes and people living in more deprived areas.

Diabetic retinopathy equity profile in a multi-ethnic, deprived population in Northern England.

Equity profiles are an established public health tool used to systematically identify and address inequity within health and health services. Our aim was to conduct an equity profile to identify inequity in eye health across Leeds and Bradford. This paper presents results of findings for diabetic retinopathy in Bradford and Airedale. A variety of routine health data were included and sub-analysed by measures of equity, including age, sex, ethnicity, and deprivation to identify inequity in eye health and healthcare. The Spearman Rank Correlation Coefficient was used to determine the association between variables. The prevalence of diagnosed diabetes in Bradford and Airedale district is 6.6% compared to 4.3% in nearby Leeds and 5.1% nationally. The age-standardised prevalence of diagnosed diabetic retinopathy within Bradford and Airedale is 2.21% (95% CI 1.54-2.26%), with a disproportionately high prevalence of disease in the Pakistani population and the most deprived parts of the population. There was a poorer uptake of diabetic retinopathy screening in more deprived parts of the district and the proportions with a higher rate of referral to ophthalmology following the screening in Black and Minority Ethnic populations compared with the white population (13.2% vs 6.9%). Uptake of secondary care outpatient appointments is much lower in more deprived populations. Inequalities are inherent in diabetic retinopathy prevalence, diagnosis, and treatment. The reasons for these inequities are multi-factorial and further investigation of reasons for poor uptake of services is required. Addressing the inequalities in eye health and healthcare requires cross-organisational collaboration.
