Abstract: isual impairment and blindness from diabetic retinopathy (DR), which can be reduced by early screening and treatment, is an emerging public health concern in low-income and middle-income countries (LMICs) owing to the increasing prevalence of diabetes mellitus (DM). However, no systematic screening exists in most LMIC settings. The Western province of Sri Lanka has the highest prevalence of DM (18.6%) in the country. A situational analysis identified a marked gap in DR screening (DRS) and treatment services uptake in this region only opportunistic screening is practiced currently. he aim of this protocol is to describe the methods of development and validation of a DRS intervention using a hand-held nonmydriatic digital camera by physician graders in a non-ophthalmological setting at a tertiary-level medical clinic to propose a valid and feasible modality to improve uptake. RS modality was developed after assessing barriers and identifying the most appropriate personnel, methods, and location for screening services, following formative research work. The validation will be conducted in a public sector tertiary care center in the Western province of Sri Lanka. The selected physicians will be trained on capturing and grading images according to a valid locally adopted protocol. Two physicians rated high on training will screen a s le of 506 people with DM at a medical clinic. They will use nonmydriatic and mydriatic 2-field imaging strategy. The validity of the proposed screening procedure will be assessed and compared with the mydriatic indirect biomicroscopic examination by a senior retinologist. he validity of screening by physician graders will be analyzed and the sensitivity, specificity, and predictive values (with 95% CIs) calculated by the dilation status and for each grader. The diagnostic accuracy at each level of severity of DR will be assessed to define the most appropriate referable criteria. Data is currently being collected. he outcome of this study will be useful for the detection of a defined level of DR at non-ophthalmological setting to filter the people with DM before referral to an eye clinic. This will be helpful to improve the uptake and identify risk groups in advance to prevent sight-threatening DR. Furthermore, evidence from this study will be useful for the implementation of a DRS program in this region and in similar communities. RR1-10.2196/10900

Abstract: There are different estimates of disability prevalence reported in India due to the differences in definitions and methodologies. Reliable data is needed to plan effective disability inclusive strategies. The objective of this study was to determine the prevalence and risk factors associated with disability among adults ≥18 years of age in Prakasam district of Andhra Pradesh using the Rapid Assessment of Disability (RAD) tool. The RAD survey was conducted in 50 villages (clusters) of Ongole ision of Prakasam district. A two-stage cluster random s ling was used. Within each village 80 participants were surveyed. Compact segment s ling was used to determine the houses included. A person was reported as disabled based on their responses to the functioning section of the RAD tool. A total of 4134 adults were included. The overall prevalence of disability was 10.4% (431 adults). The highest prevalence of functional impairment was related to mobility (4.7%) followed by vision (2.1%) and fine motor (1.8%). The prevalence of psychological distress was 2.3%. Disability was significantly more prevalent in the poor socio economic group (OR 2.8 95% CI: 1.5 5.0) and among unemployed (OR 3.6 95% CI: 2.3, 5.5). The prevalence of disability was strongly associated with age where, participants aged 70 years and over were eleven times more likely to report disability than younger age groups. The high prevalence of disability in the region points to disability being of public health concern and as a health condition needing urgent attention and specific interventions.
