Towards an effective collaboration between the South Western Sydney Local Health District and local councils: insights from a qualitative study.

BACKGROUND: Partnership between local government and local health districts is imperative, given their overlapping goals. However, the need for further evidence-informed actions to address health inequities remains. The effectiveness of such partnerships requires better insight into how local governments perceive partnerships with local health districts, and how well equipped and prepared they are to deal with the health equity opportunities and challenges. It was precisely for these reasons that a qualitative study was conducted by South Western Sydney Local Health District (SWSLHD) in 2016. OBJECTIVE: This study aims to better understand how to improve the effectiveness of collaboration between local governments and the public health sector. METHODS: Qualitative data were collected from 14 in-depth interviews with staff representing five of the local councils comprising SWSLHD. These data were then thematically analysed using inductive and deductive reasoning through the application of NVivo software. RESULTS: While councils recognize the potential value of consulting SWSLHD, limited communication and the absence of a clearly defined process for collaboration needs to be addressed. Moreover, councils perceive knowledge gaps in relation to basic issues, such as who provides what services to whom, and how to access local-government-level data from health experts. CONCLUSIONS: The study confirms the importance of providing locally relevant public health data to help address issues of mutual concern that arise during the consultation process. Moreover, it suggests that proactive and ongoing consultation between SWSLHD and councils is critical if there is to be effective engagement, and coordinated and sustained action. The concerns raised in this study echo findings from studies from other local government settings of Victoria, South Australia and New South Wales. Thus, the study findings may be applied to other councils beyond the SWSLHD.

IMI Impact of Myopia.

The global burden of myopia is growing. Myopia affected nearly 30% of the world population in 2020 and this number is expected to rise to 50% by 2050. This review aims to analyze the impact of myopia on individuals and society; summarizing the evidence for recent research on the prevalence of myopia and high myopia, lifetime pathological manifestations of myopia, direct health expenditure, and indirect costs such as lost productivity and reduced quality of life (QOL). The principal trends are a rising prevalence of myopia and high myopia, with a disproportionately greater increase in the prevalence of high myopia. This forecasts a future increase in vision loss due to uncorrected myopia as well as high myopia-related complications such as myopic macular degeneration. QOL is affected for those with uncorrected myopia, high myopia, or complications of high myopia. Overall the current global cost estimates related to direct health expenditure and lost productivity are in the billions. Health expenditure is greater in adults, reflecting the added costs due to myopia-related complications. Unless the current trajectory for the rising prevalence of myopia and high myopia change, the costs will continue to grow. The past few decades have seen the emergence of several novel approaches to prevent and slow myopia. Further work is needed to understand the life-long impact of myopia on an individual and the cost-effectiveness of the various novel approaches in reducing the burden.

Validity of self-reported anthropometrics in Arabic-speaking adults in Australia.

ISSUE ADDRESSED: Body mass index (BMI) is generally accepted as a useful measurement for monitoring risk factors in adults. Although self-reported anthropometric measurements are deemed to be more cost-effective, its accuracy has been debated. While BMI based on self-reported measures may have to be relied on, accuracy of reporting such measures among culturally and linguistically diverse groups is unknown. METHODS: Face-to-face surveys were conducted among 272 adults of Arabic-speaking backgrounds living in south western Sydney using non-probability sampling to collect data for directly measured and self-reported BMI. Agreement between both measures was determined by the Cohen's kappa coefficient analyses. The Wilcoxon matched-pairs signed-ranks and Mann-Whitney U tests were used to compare the differences in median values between both measures. The Bland-Altman analysis was conducted to identify the limits of agreement between both measurements. RESULTS: There was substantial agreement between both self-reported and directly measured data (kappa = 0.70). Significant small median differences were found between both direct and self-reported overall BMI measure (27.58 vs 27.34; P < .0001) with a significantly greater median difference for females compared to males (0.76 vs 0.38 kg/m2 ; P = .05). However, the 95% limits of agreement were moderately large for BMI (-5.1 and 6.4). CONCLUSION: Self-reported data for height and weight are generally appropriate for calculating BMI for health promotion interventions among adults from Arabic-speaking backgrounds but should be used cautiously when assessing BMI status at the individual level. SO WHAT?: When limited resources are available for accomplishing health promotion interventions, self-reporting measures may be used as a proxy for assessing BMI.

Culturally tailored tobacco control: Aboriginal community perspectives in Sydney, Australia.

INTRODUCTION: A community-based project was developed to support quit attempts and denormalise smoking in Aboriginal communities. This qualitative study evaluates the effectiveness of project strategies, messages and the partnership process, and explores impacts observed by Aboriginal community members, complementing findings from a quantitative evaluation. METHODS: The study comprised five focus groups (40 participants) and 14 in-depth interviews (with 15 community members). Data were analysed thematically by manual and NVivo software methods. RESULTS: Results demonstrate that the project attracted community attention, was well recalled and messages were considered convincing and persuasive. Participants reported being more likely to quit and to discuss smoking with family and friends, and noticed that many people were quitting. Participants observed an increase in asking people not to smoke in the home and fewer people smoking at events, but noted that many smokers struggled to stay quit. The partnership and participation of Aboriginal Health Workers were viewed as crucial. CONCLUSION: The qualitative findings reinforce quantitative evaluation findings suggesting that the project contributed to denormalising smoking and motivating quit attempts. SO WHAT: The evaluation provided insight into how the project changed attitudes and motivated community members to make quit attempts and provided ideas to meet the ongoing challenge.

Evaluating an Aboriginal tobacco social marketing project in Sydney, Australia.

INTRODUCTION: A partnership between three Aboriginal Community Controlled Organisations and a mainstream health service was formed to develop, implement and evaluate a comprehensive and culturally appropriate social marketing project which aimed to encourage smokers to quit smoking. The project also supported quit attempts and promoted denormalisation of smoking. METHODS: The project was evaluated through baseline (n = 427) and follow-up (n = 611) surveys carried out face-to-face with Aboriginal and/or Torres Strait Islander participants 18 years and older recruited through convenience sampling at community events and venues during 2010-2011 and 2015. RESULTS: The proportion of participants who had made one or more quit attempts increased significantly between baseline and follow-up surveys (54%, 101 out of 187; vs 64%, 189 out of 297; P < 0.05). Participants who had intended to quit within 6 months (AOR, 3.29; 95% CI 1.90-5.68; P < 0.01); and participants disagreeing with the statement "I don't mind if people smoke inside my home" (AOR, 1.74; 95% CI 1.06-2.84; P < 0.05) were significantly more likely to have made one or more quit attempts compared to the respective reference groups. CONCLUSION: Study findings demonstrate that the project was associated with increased quit attempts. Intention to quit and attitude were found to be the predictors of making a quit attempt. SO WHAT?: Many studies suggest the need to denormalise smoking; this study demonstrated both change in attitudes and an increase in quit attempts. It is recognised that many quit attempts may be needed for long-term smoking cessation.

"Some say no, some say yes": Receiving inconsistent or insufficient information from healthcare professionals and consequences for diabetes self-management: A qualitative study in patients with Type 2 Diabetes.

AIMS: To explore the information-seeking experiences of patients with Type 2 diabetes and how these influenced self-management behaviours. METHODS: We interviewed 18 patients with Type 2 Diabetes attending outpatient diabetes centers in South Western Sydney. Data were analyzed thematically. RESULTS: Patients described a number of challenges they faced when seeking information about diabetes self-management. One major challenge was receiving inconsistent and insufficient information from healthcare professionals, which consequently undermined patients' ability to self-manage diabetes. This became a disincentive in carrying out self-management tasks, and led to confusion and mistrust regarding the veracity of information received. Participants also described finding reliable information, and difficulty understanding and accessing relevant information as challenges. Medical jargon and lack of comprehensive explanations exacerbated knowledge deficits compounded by the complex maze of internet resources that some patients accessed. In response to what they perceived as confusing or inconsistent information, some patients followed "their own way" of managing their diabetes. CONCLUSIONS: Inconsistent information not tailored to the needs of patients adversely affects self-management. Taking time to provide simple explanations and assisting patients in navigating reliable web resources is becoming a vital role of healthcare professionals to reduce knowledge gaps in patients with low health literacy.

Cross-sectional study protocol for the Arabic Healthy Weight Project promoting active living and healthy eating among Arabic-speaking communities in South Western Sydney.

INTRODUCTION: The South Western Sydney Local Health District (SWSLHD) is home to nearly 75 000 Arabic-speaking people. Of these, nearly three quarters are overweight or obese and suffer from a range of chronic diseases. To address this, the Health Promotion Service of SWSLHD will conduct a community-based overweight and obesity prevention intervention (Arabic Healthy Weight Project, 2018-2021) with Arabic community members aged between 18 and 50 years. The intervention's main activities will include a comprehensive social marketing campaign and an 'Eat-Move-Live Healthy' programme. METHODS AND ANALYSIS: The project will be evaluated using a pre-postintervention study design to measure changes in practices in relation to physical activity, consumption of vegetables and intake of sugar-sweetened beverages. The evaluation will apply mixed data collection methods. The quantitative data will be collected using a face-to-face survey of 1540 participants from two independent samples (pre: 770 and post: 770). Descriptive and inferential statistical tests will be used to analyse the quantitative data. The qualitative component will use focus group discussions and interviews to evaluate the formative, process and follow-up phases of data collection. A combination of deductive and inductive methods of data analysis will be conducted using NVivo software. ETHICS AND DISSEMINATION: The protocol has been approved by the Human Research Ethics Committee of SWSLHD (HREC/16/LPOOL/303). Findings will be published in peer-reviewed journals.

Effect of school eye health promotion on children's eye health literacy in Vietnam.

Health promotion intervention in schools is a useful strategy to improve students' health awareness. The purpose of this study was to assess the effect of eye health promotion interventions on eye health literacy in school children in Vietnam. A piloted questionnaire was administered to 300 children from five secondary schools in Ba Ria-Vung Tau, Vietnam at baseline and re-administered after the eye health promotion interventions. McNemar chi-square and logistic regression were used for statistical analysis. A total of 300 children aged 12-15 years (mean, 13.3 ± 1.3 years; 60% female) participated in the baseline survey. The participation rate in the post-health promotion survey was 94.7%. After the health promotion interventions, number of children who had correct eye health knowledge increased by 10-20% (60-75% to 70-95%), more children reported having had an eye examination (63.3% to 84.7%; p < 0.001) and more reported wearing spectacles (36.1% to 43.4%; p = 0.04). Children in urban schools were twice as likely to have improved knowledge of vision loss compared with children in rural schools (odds ratio, 2.1-4.1; p = 0.01 to p < 0.001). Children from rural schools had significantly higher odds of visiting doctor after the eye problems worsened (odds ratio, 4.5; p < 0.001). These results imply that eye health promotion interventions significantly improve eye health knowledge, attitudes and practices of school children. Additionally, participation of parents and teachers as change agents may further improve children's health literacy.

Accuracy of vision technicians in screening ocular pathology at rural vision centres of southern India.

BACKGROUND: There is paucity of data on the inter-observer agreement and diagnostic accuracy between a primary-care technician (vision technician) and an ophthalmologist. Hence, the current study was conducted to assess the accuracy of vision technicians, to screen potentially sight-threatening ocular conditions at rural vision centres of southern India and their agreement with an ophthalmologist. METHODS: In July to August 2010, patients presenting to seven vision centres in Adilabad district (Andhra Pradesh) were selected and screened in a masked manner by seven vision technicians followed by an examination by a consultant ophthalmologist. Agreement was assessed between vision technicians and the ophthalmologist for screening of potential sight-threatening ocular conditions and decisions for referral. The ophthalmologist's findings were considered as the reference standard. RESULTS: Two hundred and seventy-nine patients were enrolled at seven vision centres with a mean age of 32.9 ± 21.8 years. Agreement for screening of ocular pathology was 0.82 (95 per cent CI, 0.8-0.83). There was excellent agreement for cataract (0.97; 95 per cent CI, 0.93-1), refractive error (0.98; 95 per cent CI, 0.96-1), corneal pathology (1.0; 95 per cent CI, 1.0-1.0) and other anterior segment pathology (0.95; 95 per cent CI, 0.9-1); the agreement was moderate to fair for detection of glaucoma suspects (0.43; 95 per cent CI, 0.28-0.60) and retinal pathology (0.39; 95 per cent CI, 0.14-0.63). Sensitivity for screening of anterior segment pathology was 94.6-100 per cent. There was a fair to moderate sensitivity for glaucoma suspect; 35.6 per cent (95 per cent CI, 21.9-51.2) and retinal pathology 26.3 per cent (95 per cent CI, 9.2-51.2). Specificity for screening of ocular pathology was 98.2 to 100 per cent. The kappa (κ) agreement for referral for any pathology was 0.82 (0.8-0.83) CONCLUSION: As there is good agreement between the vision technicians and the ophthalmologist for screening and referral of anterior segment pathology but moderate to fair for glaucoma suspects and retinal pathology, vision technicians would be a good resource at the primary level to screen for anterior segment pathology; however, they may need further training to detect posterior segment pathology.

Validity of Teacher-Based Vision Screening and Factors Associated with the Accuracy of Vision Screening in Vietnamese Children.

PURPOSE: To assess validity of teacher-based vision screening and elicit factors associated with accuracy of vision screening in Vietnam. METHODS: After brief training, teachers independently measured visual acuity (VA) in 555 children aged 12-15 years in Ba Ria - Vung Tau Province. Teacher VA measurements were compared to those of refractionists. Sensitivity, specificity, positive predictive value and negative predictive value were calculated for uncorrected VA (UVA) and presenting VA (PVA) 20/40 or worse in either eye. Chi-square, Fisher's exact test and multivariate logistic regression were used to assess factors associated with accuracy of vision screening. Level of significance was set at 5%. RESULTS: Trained teachers in Vietnam demonstrated 86.7% sensitivity, 95.7% specificity, 86.7% positive predictive value and 95.7% negative predictive value in identifying children with visual impairment using the UVA measurement. PVA measurement revealed low accuracy for teachers, which was significantly associated with child's age, sex, spectacle wear and myopic status, but UVA measurement showed no such associations. CONCLUSIONS: Better accuracy was achieved in measurement of VA and identification of children with visual impairment using UVA measurement compared to PVA. UVA measurement is recommended for teacher-based vision screening programs.

Reasons for refusing cataract surgery in illiterate individuals in a tribal area of Andhra Pradesh, India.

PURPOSE: To assess the reasons for refusing cataract surgery in illiterate individuals in a tribal area of India. METHODS: A prospective study evaluated 1046 subjects who had undergone screening in eye camps and included 398 of 492 referred subjects with cataract who refused to seek cataract surgery. Subjects were assessed to elicit general and specific reasons for non-compliance. Multiple logistic regression analysis was applied to determine the associations; p < 0.05 was considered significant. RESULTS: Overall, 83% (329/398) of subjects reported that they could manage with their current vision. The five most common reasons they did not proceed with cataract surgery were: fear of losing current vision, work priority, lack of support systems, a dependency due to old age, and expenses required after surgery. Odds of seeking treatment were lower among unemployed subjects (odds ratio, OR, 0.4, 95% confidence interval, CI, 0.19-0.86; p = 0.01) and in patients with family income <1000 Indian rupees per month (OR 0.5, 95% CI 0.34-0.94; p = 0.02), and higher among those unilaterally blind (OR 10.8, 95% CI 3.3-35.6; p ≤ 0.01). CONCLUSION: In a tribal setting, 83% of individuals referred for cataract surgery did not proceed with surgery. Reasons given for non-compliance were not directly related to the surgery but focused on valid day-to-day difficulties anticipated to increase following surgery. Beyond accessibility and cost of surgery, other social and infrastructural factors need to be addressed to increase the uptake of cataract surgery.

Key factors determining success of primary eye care through vision centres in rural India: patients' perspectives.

AIM: This paper intends to discuss the patients' perspective on the determinants of primary eye care services from vision centers (VC) in rural India. MATERIALS AND METHODS: A retrospective study design and interview method was used on 127 randomly selected patients who accessed the 4 VCs in 2007. Factor analyses and linear regression models were used to predict the associations with patient satisfaction. RESULTS: The three factors derived from factor analyses were: (1)-vision technician (VT), (2)-location of VC, and (3)-access to VC; explaining 60% of the variance in total patients' satisfaction with VC. The first model (R2 : 0.61; F 1,124=144.36, P <0.001), indicated that respondents who had 'difficulty to travel to the place of VC' and those who can afford to pay had less satisfaction with VT services. The second model (R2 =0.18; F 1,124=29.5, P <0.001) explained that respondents' difficulty to identify the building of VC had decreased patients' satisfaction and the third model (R2 =0.36; F 1,124=45.6, P <0.001) indicated that those who had to travel<5 km to the VC and had 0.38 units of increased satisfaction level with the services of VC. CONCLUSION: A good VT can enhance patient satisfaction. However, patient expectations are not only confined to the provider but also other factors such as ability to pay and convenient transportation that helps patients reach the location of the VC with ease.

Comparison of patient satisfaction with services of vision centers in rural areas of Andhra Pradesh, India.

AIM: To compare the satisfaction of patients with the services of Vision Center services (primary eye care) in large village (s) and small village (s) in rural settings in Andhra Pradesh state, India. MATERIALS AND METHODS: We have administered standard questionnaires to randomly selected patients to assess patient satisfaction when assessing Vision Center Services. We used the Chi-square ( P <0.05) to explore differences in satisfaction of patients with Vision Center services located in the large village (s) and small village (s) rural settings. RESULTS: Vision Center patients at the large village (s) expressed higher levels of satisfaction (median 78%) than patients treated at the Vision Center at small village (s) (median 69%). The difference was statistically significant (Chi square P value ranging from <0.001 to 0.03) for all the items except two - 'easy to identify vision center location' and 'spectacles dispensing time' as compared to other (privately run optometry) facilities (Chi square P value=0.498 and 0.993 respectively). The location of the Vision Center, convenience of journey, ophthalmic technician's behavior with patients, are some of the most important factors that determined the patient perception about Vision Center services. CONCLUSION: The overall satisfaction levels of the Vision Center experience at 78% and 69% were good. However, continual improvement is to be made in service time, staff performance, cost and quality of vision care, especially at more remote primary eye Care Centers.

An estimate of patient costs and benefits of the new primary eye care model utilization through vision centers in Andhra Pradesh, India.

Little or no work has been carried out in developing countries on costs to patients and patient benefits in accessing primary eye care services. The purpose of this study was to assess the indirect, direct, and overall costs of patients accessing vision care at vision center services (New Primary Eyecare Approach) as compared with the nearest private clinic. The authors used a standardized questionnaire and a paired sample t test to check the significance of difference of costs. They considered a P value of <.05 as significant in this study. The total costs were significantly lower for patients who accessed the vision centers compared with the costs these patients may have incurred if they had sought services from the nearest town-based clinic (mean in Indian rupees [INR] of 178.4 ± 48.3, standard error of the mean = 4.2, and INR 366.2 ± 48.2, standard error of the mean = 4.2, respectively, t test P value < .001). vision centers, besides providing quality eye care services, offer substantial cost savings to rural populations compared with town-based optical clinics.

Barriers to accessing eye care services among visually impaired populations in rural Andhra Pradesh, South India.

PURPOSE: To understand the reasons why people in rural south India with visual impairment arising from various ocular diseases do not seek eye care. MATERIALS AND METHODS: A total of 5,573 persons above the age of 15 were interviewed and examined in the South Indian state of Andhra Pradesh covering the districts of Adilabad, West Godavari and Mahaboobnagar. A pre-tested structured questionnaire on barriers to eye care was administered by trained field investigators. RESULTS: Of the eligible subjects, 1234 (22.1%, N=5573)) presented with distant visual acuity < 20/60 or equivalent visual field loss in the better eye. Of these, 898 (72.7%, N=1234) subjects had not sought treatment despite noticing a decrease in vision citing personal, economic and social reasons. The analysis also showed that the odds of seeking treatment was significantly higher for literates [odds ratio (OR) 1.91, 95% confidence interval (CI) 1.38 to 2.65], for those who would be defined as blind by visual acuity category (OR 1.35, 95% CI 0.96 to 1.90) and for those with cataract and other causes of visual impairment (OR 1.50, 95% CI 1.11 to 2.03). Barriers to seeking treatment among those who had not sought treatment despite noticing a decrease in vision over the past five years were personal in 52% of the respondents, economic in 37% and social in 21%. CONCLUSION: Routine planning for eye care services in rural areas of India must address the barriers to eye care perceived by communities to increase the utilization of services.

Awareness of glaucoma in the rural population of Southern India.

PURPOSE: To explore the awareness of glaucoma amongst the rural population of Andhra Pradesh, India. MATERIALS AND METHODS: A total of 7775 subjects of all ages, representative of the rural population of Andhra Pradesh, participated in the Andhra Pradesh Eye Disease Study. The responses of subjects older than 15 years (n=5573) who completed a structured questionnaire regarding awareness (heard of glaucoma) and knowledge (understanding of disease) of glaucoma formed the basis of this study. RESULTS: Awareness of glaucoma (n=18; 0.32%) was very poor in this rural population, and females were significantly less aware (p=0.007). Awareness of glaucoma was also significantly less among illiterate persons (p<0.0001), and socially backward population (p<0.0001). Majority of the respondents who were aware of glaucoma (n=10; 55.6%) did not know if visual loss due to glaucoma was permanent or reversible. The major source of awareness of glaucoma in this population was TV/magazines and other media followed by information from a relative or acquaintance suffering from the disease. CONCLUSION: Awareness of glaucoma is very poor in the rural areas of southern India. The data suggest the need for community-based health education programmes to increase the level of awareness and knowledge about glaucoma.

Awareness of eye donation in the rural population of India.

PURPOSE: To determine the "awareness of eye donation" and "willingness to pledge eyes for donation" in the rural population of Andhra Pradesh, southern India. METHODS: A total of 7,775 subjects of all ages, representative of the rural population of Andhra Pradesh, participated in the Andhra Pradesh Eye Disease Study (APEDS). Subjects older than 15 years were interviewed regarding awareness of eye donation and willingness to pledge eyes for donation. RESULTS: Age-gender adjusted prevalence of awareness of eye donation in this population was 30.7% (95% CI: 29.5-31.9) but only 0.1% (age-gender adjusted prevalence) (95% CI: 0.05-0.25) had pledged eyes. On multivariate analysis the awareness of eye donation was significantly less in those subjects > or = 70 years old (OR 0.7; 95% CI: 0.6-0.8), illiterates (OR 0.2; 95% CI: 0.1-0.2), females (OR 0.8; 95% CI: 0.7-0.9), lower socioeconomic status group (OR 0.4; 95% CI: 0.4-0.5) and Christians (OR 0.2; 95% CI: 0.1-0.6). Media comprised the major source of information about eye donation. Of those aware of eye donation, 32.9% were willing to pledge eyes, and 50.6% needed more information to decide whether or not to pledge their eyes. CONCLUSIONS: There needs to be more transfer of knowledge if more eyes are to be pledged. One-third of those aware of eye donation have not pledged their eyes, and an additional 50.6% needed more information to decide. This means only about one-fifth of those aware of eye donations have pledged their eyes.

Fear of blindness and perceptions about blind people. The Andhra Pradesh Eye Disease Study.

This study assessed the fear of being affected by illness and disability including blindness, and perceptions of the population towards blind people in the Indian state of Andhra Pradesh. A total of 11,786 subjects of all ages were sampled from 94 clusters in one urban and three rural study areas of Andhra Pradesh using stratified, random, cluster, systematic sampling to represent the population of this state. A total of 10,293 subjects of all ages underwent a detailed interview and dilated ocular evaluation. Subjects > 15 years of age (7,432) were interviewed regarding fear of illness/disability and their perceptions of blind people. The fear of blindness was assessed in comparison to cancer, severe mental illness, heart attack, losing limbs, deafness, inability to speak, and paralysis. A majority of the study population feared all the illnesses and disabilities assessed. The prevalence of fear of blindness was 90.9% (95% confidence interval 89.1-92.8%) and 92.1% (95% confidence interval 90.6-93.6%) in urban and rural study areas respectively. With multiple logistic regression the fear of blindness was significantly higher for those with any level of education and for those living in the rural study areas. The proportion of those having positive feelings towards blind people was higher in the urban study area. A high prevalence of blindness, 1.84%, has been reported in this population previously. These data suggest that this population feared blindness, and yet there is a high rate of blindness. This reflects the need for increasing awareness about blindness in this population through eye health promotion strategies in order to reduce blindness, and awareness regarding the availability of rehabilitation services.

Population-based study of spectacles use in southern India.

This study assessed the use of spectacles and its demographic associations in a sample representative of the population of the Indian state of Andhra Pradesh. A total of 11,786 subjects of all ages were sampled from 94 clusters in one urban and three rural study areas of Andhra Pradesh using stratified, random, cluster, systematic sampling. The eligible subjects underwent detailed interview and eye examination including dilated examination of the posterior segment. The data on the use of spectacles were analysed for subjects > 15 years of age. A total of 7,432 subjects > 15 years of age participated in the study of whom 1,030 (13.8%) had a refractive error of spherical equivalent +/- 3.00 Diopter or worse. The prevalence of current use of spectacles in those with spherical equivalent +/- 3.00 Diopter or worse, who were likely to be visually impaired without refractive correction, was 34.2% (95% confidence interval 30.3-38%) and of previous use of spectacles was 12.3% (95% confidence interval 10.3-14.3%). The odds of using spectacles currently were significantly higher for those with any level of education, those living in the urban area, and for those with aphakia or psuedophakia as compared with natural refractive error. Among those who had used spectacles previously, 43.8% had discontinued because they felt that either the prescription was incorrect or that the spectacles were uncomfortable, suggesting poor quality of refractive services, and another 19.6% had lost the pair and could not afford to buy another pair. These data suggest that the use of spectacles in this population by those with refractive error was not optimal. Two-thirds of those with spherical equivalent +/- 3.00 Diopter or worse were not using spectacles. Of those who had discontinued the use of spectacles, a significant proportion did so for reasons related to poor quality of refractive services. Strategies such as vision screening programmes and eye health promotion need to be implemented, the quality of refractive services monitored and the cost of spectacles regulated, if the substantial burden of visual impairment due to refractive error in this population is to be reduced.
