Cross-sectional study of prevalence and correlates of fear of falling in the older people in residential care in India: the Hyderabad Ocular Morbidity in Elderly Study (HOMES).

OBJECTIVE: To report the prevalence and risk factors for the fear of falling (FOF) among older individuals living in residential care facilities in India. DESIGN: Cross-sectional study. SETTING: Homes for the aged centres in Hyderabad, India. PARTICIPANTS: The study included individuals aged ≥60 years from homes for the aged centres. The participants underwent a comprehensive eye examination in make-shift clinics setup in homes. Trained investigators collected the personal and demographic information of the participants and administered the Patient Health Questionnaire-9 and Hearing Handicap Inventory for Elderly questionnaire in the vernacular language. FOF was assessed using the Short Falls Efficacy Scale. The presence of hearing and visual impairment in the same individual was considered dual sensory impairment (DSI). A multiple logistic regression analysis was done to assess the factors associated with FOF. PRIMARY OUTCOME MEASURE: FOF. RESULTS: In total, 867 participants were included from 41 homes for the aged centres in the analyses. The mean (±SD) age of the participants was 74.2 (±8.3) years (range 60-96 years). The prevalence of FOF was 56.1% (95% CI 52.7% to 59.4%; n=486). The multivariate analysis showed that those with DSI had eleven times higher odds of reporting FOF than those with no impairment (OR 11.14; 95% CI 3.15 to 41.4.) Similarly, those with moderate depression had seven times higher odds (OR 6.85; 95% CI 3.70 to 12.70), and those with severe depression had eight times higher odds (OR 8.13; 95% CI 3.50 to 18.90) of reporting FOF. A history of falls in the last year was also associated with increased odds for FOF (OR 1.52; 95% CI 1.03 to 2.26). CONCLUSION: FOF is common among older individuals in residential care in India. Depression, falling in the previous year and DSI were strongly associated with FOF. A cross-disciplinary approach may be required to address FOF among the older people in residential care in India.

Barriers to uptake of referral eye care services among the elderly in residential care: the Hyderabad Ocular Morbidity in Elderly Study (HOMES).

BACKGROUND: To report on the barriers to uptake of eye care services after referral in the elderly in 'homes for the aged' in Hyderabad, India. METHODS: Individuals aged ≥60 years were recruited from 41 'homes for the aged' and were examined in the 'make-shift' clinics in homes. All participants who had vision impairment or needed further eye examination other than spectacles were referred to the higher centres for 'free services'. Three months after the referral, the participants were interviewed and asked about the uptake of services, and their reasons for not attending. RESULTS: In all, 731/1182 (61.8%) participants were referred of which 375 (49.9%) attended. In multiple logistic regression, participants aged ≥80 years were less likely to utilise the services (OR 0.60; 95% CI 0.39 to 0.03). Similarly, the participants living in free homes (OR 3.53; 95% CI 2.15 to 5.79) and subsidised homes (OR 2.24: 95% CI 1.55 to 3.23) and those independently mobile had higher odds for uptake of services (OR 5.74; 95% CI 3.31 to 10.51). The major reasons for not availing the referral services were 'lack of felt need' reported by 136 (45.4%) participants followed by other health issues in 100 (33.4%) participants and non-consenting family members in 49 (16.4%) participants. In all, 14 (4.7%) participants gave other reasons. CONCLUSIONS: The uptake of eye care services in the elderly in residential care remains poor despite the provision of services for free. Lack of felt need for services is the main reason for non-compliance to the referral for care. Counselling on the benefit of interventions could potentially improve referral compliance in this population.

Prevalence and causes of vision loss in sub-Saharan Africa in 2015: magnitude, temporal trends and projections.

BACKGROUND: This study aimed to assess the prevalence and causes of vision loss in sub-Saharan Africa (SSA) in 2015, compared with prior years, and to estimate expected values for 2020. METHODS: A systematic review and meta-analysis assessed the prevalence of blindness (presenting distance visual acuity <3/60 in the better eye), moderate and severe vision impairment (MSVI; presenting distance visual acuity <6/18 but ≥3/60) and mild vision impairment (MVI; presenting distance visual acuity <6/12 and ≥6/18), and also near vision impairment (

Prevalence and causes of vision loss in East Asia in 2015: magnitude, temporal trends and projections.

BACKGROUND: To determine the prevalence and causes of blindness and vision impairment (VI) in East Asia in 2015 and to forecast the trend to 2020. METHODS: Through a systematic literature review and meta-analysis, we estimated prevalence of blindness (presenting visual acuity <3/60 in the better eye), moderate-to-severe vision impairment (MSVI; 3/60≤presenting visual acuity <6/18), mild vision impairment (mild VI: 6/18≤presenting visual acuity <6/12) and uncorrected presbyopia for 1990, 2010, 2015 and 2020. A total of 44 population-based studies were included. RESULTS: In 2015, age-standardised prevalence of blindness, MSVI, mild VI and uncorrected presbyopia was 0.37% (80% uncertainty interval (UI) 0.12%-0.68%), 3.06% (80% UI 1.35%-5.16%) and 2.65% (80% UI 0.92%-4.91%), 32.91% (80% UI 18.72%-48.47%), respectively, in East Asia. Cataract was the leading cause of blindness (43.6%), followed by uncorrected refractive error (12.9%), glaucoma, age-related macular degeneration, corneal diseases, trachoma and diabetic retinopathy (DR). The leading cause for MSVI was uncorrected refractive error, followed by cataract, age-related macular degeneration, glaucoma, corneal disease, trachoma and DR. The burden of VI due to uncorrected refractive error, cataracts, glaucoma and DR has continued to rise over the decades reported. CONCLUSIONS: Addressing the public healthcare barriers for cataract and uncorrected refractive error can help eliminate almost 57% of all blindness cases in this region. Therefore, public healthcare efforts should be focused on effective screening and effective patient education, with access to high-quality healthcare.

Task sharing: situation analysis about capacity and resources for management of diabetic retinopathy in Pakistan.

AIM: To assess the capacity and resources of eye care facilities, using the WHO Health Systems Framework, to manage diabetic retinopathy (DR) through task sharing. METHODS: Using purposive sampling, four participants (administrators) from four selected hospitals in two provinces in Pakistan were recruited for this cross-sectional study. A survey, to assess the capacity and resources of the selected eye care facilities for the feasibility to adopt task sharing in management of DR to prevent vision loss, was emailed to participants who were asked to complete. Responses to open-ended questions were entered into a Microsoft Excel spread sheet and inductive approach was applied for analysis. RESULTS: All the surveyed eye care facilities offer eye care services for people with diabetes and DR. All surveyed eye care facilities have a shortage in the number of human resources across all cadres. Optometrists and mid-level eye care workers did not have active roles in DR screening and management in all four hospitals. All the hospitals surveyed did not have a computerized record management system for patients who visit ophthalmologists for eye examinations. Equipment for detection and management of DR were short in number and main users were ophthalmologists. There was no policy for population-based screening program for detection of DR in any of the surveyed hospitals. CONCLUSION: A system-based approach to manage DR is needed. The capacity of eye care facilities and the potential to improve access of people with diabetes to eye care services can be enhanced through implementation of task sharing.

Prevalence and causes of vision loss in South-east Asia and Oceania in 2015: magnitude, temporal trends and projections.

BACKGROUND: To assess prevalence and causes of vision impairment in South-east Asia and Oceania regions from 1990 to 2015 and to forecast the figures for 2020. METHODS: Based on a systematic review of medical literature, prevalence of blindness (presenting visual acuity (PVA) <3/60 in the better eye), moderate and severe vision impairment (MSVI; PVA <6/18 but ≥3/60), mild vision impairment (PVA <6/12 but ≥6/18) and near vision impairment (>N5 or N8 in the presence of normal vision) were estimated for 1990, 2010, 2015 and 2020. RESULTS: The age-standardised prevalence of blindness for all ages and both genders was higher in the Oceania region but lower for MSVI when comparing the subregions. The prevalence of near vision impairment in people≥50 years was 41% (uncertainty interval (UI) 18.8 to 65.9). Comparison of the data for 2015 with 2020 predicts a small increase in the numbers of people affected by blindness, MSVI and mild VI in both subregions. The numbers predicted for near VI in South-east Asia are from 90.68 million in 2015 to 102.88 million in 2020. The main causes of blindness and MSVI in both subregions in 2015 were cataract, uncorrected refractive error, glaucoma, corneal disease and age-related macular degeneration. There was no trachoma in Oceania from 1990 and decreasing prevalence in South-east Asia with elimination predicted by 2020. CONCLUSIONS: In both regions, the main challenges for eye care come from cataract which remains the main cause of blindness with uncorrected refractive error the main cause of MSVI. The trend between 1990 and 2015 is for a lower prevalence of blindness and MSVI in both regions.

Task sharing: Development of evidence-based co-management strategy model for screening, detection, and management of diabetic retinopathy.

BACKGROUND: The number of adults with diabetes is increasing worldwide and also the number of people with diabetic retinopathy (DR), a major complication of diabetes. Task sharing in eye care for people with diabetes could address the shortage in the number of ophthalmologists and increase access to eye care services. This study investigated the opinion of eye care professionals for a checklist of tasks, which are involved in DR management, to be possibly shared by optometrists and mid-level eye and health care workers with ophthalmologists. METHODS: The study used a purposive sampling technique. All available eye and health care workers from five selected hospitals in two provinces in Pakistan were recruited. A cross-sectional survey was conducted to investigate the potential roles of various cadres in eye care delivery for people with diabetes. RESULTS: Ninety-six (79%) participants including doctors (n = 56), optometrists (n = 29), and mid-level eye care workers (n = 11) responded to the survey. Two-thirds of the participants suggested mid-level eye care workers, while 88.5% stated that lady health workers could provide education and health promotion to people with diabetes. Most of the participants (88.5%) suggested that optometrists could share the task of dilated ophthalmoscopy with ophthalmologists for detection of DR and make referrals to ophthalmologists if needed. Ophthalmologists remained the recommended cadre to undertake the eye examinations of patients with proliferative DR and diabetic macular edema. CONCLUSION: This research provided an insight on how task sharing in DR management can be implemented by optimizing the roles of eye care workers.

Task sharing in the eye care workforce: Screening, detection, and management of diabetic retinopathy in Pakistan. A case study.

PURPOSE: Diabetic retinopathy (DR) is a preventable cause of vision loss. Reducing vision loss due to DR and providing access to eye care services for people with diabetes have been severely constrained by a shortage in the number of ophthalmologists. This study aimed to explore the potential for task sharing in the eye care workforce for screening, detection, and management of DR. METHODS: Using purposive sampling, 24 participants were recruited from four selected hospitals in 2 provinces in Pakistan. Face-to-face interviews were conducted to explore the potential for task sharing in DR management. RESULTS: Amongst 24 participants recruited, 22 (91.7%) including administrators (n = 3), ophthalmologists (n = 10), optometrists (n = 3), mid-level eye care workers (n = 4), and endocrinologist (2) participated in the study. All participants indicated the need for an organised screening program for DR detection through task sharing. Participants suggested that people with diabetes can be sent directly to an optometrist for initial eye exams, rather than making them wait to be examined by an ophthalmologist. Factors favouring task sharing included the name task sharing rather than task shifting and a high demand for eye care services. Major barriers to implementation of task sharing included the lack of a trained eye care workforce in the healthcare system and the lack of coordination amongst health professionals and policy makers. CONCLUSION: Participants were accepting task sharing approach and believed that task sharing could improve access to eye care services for people with diabetes and better utilise the services of eye and healthcare providers.

Impact of a low-vision self-management program on informal caregivers.

PURPOSE: To evaluate caregivers' experiences and outcomes following attendance at a patient-centered group-based self-management program called "Living with Low Vision." METHODS: Participants were caregivers of adults with low vision. A pre-post study design evaluated the impact of the program on single-item indicators that assessed levels of understanding of low vision, awareness of devices, aids and practical strategies, and questionnaires to assess confidence to deal with low vision, self-efficacy, and emotional well being. Participants formed three groups: (1) those who attended the program [intervention group 1 (IG1)] and received a take-home pack; (2) those who received a take-home pack only [intervention group 2 (IG2)]; and (3) those who received no intervention [comparison group (CG)]. RESULTS: Sixty participants (IG1 = 16, IG2 = 33, CG = 11) with mean (SD) age 67.2 years (SD = 14.8) were recruited. Half (n = 31; 51.7%) were the spouse of the adults with low vision. With the exception of two single-item indicators that assessed awareness of low-vision aids and practical strategies; no significant group differences on follow-up scores between the three study groups were found on any measure. Compared with CG participants, IG1 and IG2 participants demonstrated significantly greater awareness of low-vision aids and practical strategies (p < 0.05, for all). In addition, IG1 participants demonstrated significantly improved awareness of practical strategies than IG2 participants (p = 0.024). Most IG1 participants (n = 10; 62.5%) agreed that the program was relevant and helpful, and most would recommend it to other caregivers. CONCLUSIONS: Involving caregivers in a patient-centered group-based self-management program and providing them with an informative take-home self-help pack improved their awareness of low-vision aids, devices, and practical strategies. Our findings should be followed up with larger studies to clearly identify optimal ways of providing caregivers with information and problem-solving skills to effectively manage the demands of low vision.

A global survey of low vision service provision.

PURPOSE: To conduct a global survey of low vision services to describe the needs, priorities, and barriers in provision and coverage. METHODS: Data were mainly derived from a survey and from some secondary sources. The survey was distributed to Vision 2020 contacts, government, and non-government organizations (NGOs) in 195 countries during 2006-2008. Themes in the survey were: epidemiology of low vision, policies on low vision, provision of services, human resources, barriers to service delivery, equipment availability, and monitoring and evaluation of service outcomes. Contradictory and/or incomplete data were returned for further clarification and verification. The Human Poverty Index was used to compare the findings from developed and developing countries. RESULTS: Service availability was established for 178/195 countries, with 115 having some low vision service. Approximately half the countries in the African and Western Pacific regions have no services. Few countries have >10 low vision health professionals per 10 million of population. In many of the countries NGOs were the main providers and funders. Funding and awareness were frequently cited as barriers to service access. Women, people with disabilities, and rural dwellers were less likely to access services. There were few reports of monitoring and evaluation into the quality and impact of services. CONCLUSION: This global survey provides the first consolidated baseline of low vision service provision. Where data are available, coverage of services is generally poor. Low vision health professional numbers are low. Services in over half of the world's countries are funded by NGOs, raising issues of sustainability.

Identifying the critical success factors in the coverage of low vision services using the classification analysis and regression tree methodology.

PURPOSE: To identify the critical success factors (CSF) associated with coverage of low vision services. METHODS: Data were collected from a survey distributed to Vision 2020 contacts, government, and non-government organizations (NGOs) in 195 countries. The Classification and Regression Tree Analysis (CART) was used to identify the critical success factors of low vision service coverage. Independent variables were sourced from the survey: policies, epidemiology, provision of services, equipment and infrastructure, barriers to services, human resources, and monitoring and evaluation. Socioeconomic and demographic independent variables: health expenditure, population statistics, development status, and human resources in general, were sourced from the World Health Organization (WHO), World Bank, and the United Nations (UN). RESULTS: The findings identified that having >50% of children obtaining devices when prescribed (χ(2) = 44; P < 0.000), multidisciplinary care (χ(2) = 14.54; P = 0.002), >3 rehabilitation workers per 10 million of population (χ(2) = 4.50; P = 0.034), higher percentage of population urbanized (χ(2) = 14.54; P = 0.002), a level of private investment (χ(2) = 14.55; P = 0.015), and being fully funded by government (χ(2) = 6.02; P = 0.014), are critical success factors associated with coverage of low vision services. CONCLUSIONS: This study identified the most important predictors for countries with better low vision coverage. The CART is a useful and suitable methodology in survey research and is a novel way to simplify a complex global public health issue in eye care.

Factors associated with regular eye examinations in people with diabetes: results from the Victorian Population Health Survey.

PURPOSE: Although diabetes increases the risk of becoming visually impaired or blind, a large proportion of people with diabetes are not receiving the recommended eye care to detect and prevent retinopathy. Assessing a broad range of demographic, health behavior, and societal characteristics in relation to eye care utilization, the present study aims to increase knowledge about the potential impact of such factors on eye care utilization. METHODS: In 2003, for the first time, the annual Victorian Population Health Survey (VPHS) incorporated various eye health-related questions. Approximately 12,600 primary approach letters were mailed to all eligible and randomly selected households. Using computer-assisted telephone interviewing (CATI), the interviewer selected the person aged 18 years or over with the most recent birthday within the contacted household. RESULTS: The mean age of all 7500 participants was 47.7 years (range, 18-99 years). Six percent (n = 424) of all participants had diabetes, of whom 80% (n = 345) reported a visit to an eye care specialist within the last 2 years. People with diabetes were more likely to have had an eye test within the last 2 years if they had seen a healthcare provider or had one of various health checks, including checks not related to diabetes, within the same time. CONCLUSION: Results suggest that people who take an interest in their general health may also be more aware of the importance of eye examinations to avoid vision loss. Eye health promotion activities therefore need to broaden their reach to approach from outside the health sector, targeting people with diabetes who normally do not receive health checks. The importance of dilated eye examinations for people with diabetes needs to be further promoted for eye care providers.
