Abstract
PURPOSE To investigate general and electronic health literacy (HL) levels in prosthetic eye wearing patients, to define factors associated with reduced HL, and to identify a potential healthcare gap. METHODS In this prospective cross-sectional study 148 prosthetic eye wearers were screened using the 16-item European Health Literacy Survey Questionnaire (HLS-EU-Q16) and the 8-item electronic Health Literacy Scale (eHEALS). HLS-EU-16 and eHEALS scores were correlated to health levels, vision functioning, and sociodemographic factors. RESULTS A total of 85 patients (57%) had adequate, 38 (26%) problematic, and 9 (6%) inadequate general HL, while 16 (11%) had no valid HLS-EU-Q16 score. General HL was positively correlated with physical health (p = 0.009) and negatively with a migration background (p = 0.023). There was a positive correlation between electronic HL and educational level (p < 0.001), social status (p = 0.048), and mental health (p = 0.013). Higher age was associated with lower electronic HL (p < 0.001). CONCLUSIONS More than 30% of the prosthetic eye wearers had problematic or even inadequate general HL, suggesting a significant health care gap. To identify patients with reduced HL, a standardized screening tool should be implemented as part of routine clinical care. Within integrated care, patients with insufficient HL should be offered barrier-free advisory services and information brochures in various languages.

Exploring the Quality of Life Related to Health and Vision in a Group of Patients with Diabetic Retinopathy. Healthcare (Basel) 2022; 10:142. [PMID: 35052305 PMCID: PMC8775606 DOI: 10.3390/healthcare10010142] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 01/05/2022] [Accepted: 01/10/2022] [Indexed: 12/27/2022] Open
Abstract
(1) Background: Visual impairment of people with diabetic retinopathy (DR) and its high impact on different dimensions of their lives can cause a significant deterioration in the quality of life. The aim of this study was to examine the association and relationship between quality of life related to vision and the relevant clinical and sociodemographic variables in a group of patients with DR in Spain. (2) Methods: A descriptive cross-sectional study was conducted in all patients with DR over 18 years under follow-up in the Retina Service of the University Hospital of Burgos (HUBU), recruited during the months of January and February 2020. The main study variable was quality of life related to health and vision, obtained using the National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ-25). (3) Results: In total 87 participants made up the sample, and significant differences were found in the NEI-VFQ-25 according to gender, type of diabetes, episodes of decompensated diabetes and high blood pressure (HBP) (p < 0.05). Best-corrected visual acuity (BCVA) was also correlated with the NEI-VFQ-25 (p < 0.05). (4) Conclusions: These data could facilitate the design of action protocols focused on the well-being of the patient, in addition to considering the clinical characteristics. Further studies are needed to help understand the causal relationship between variables and that includes a wider variety of factors.

Abstract
PURPOSE To investigate anxiety and depression levels in prosthetic eye-wearing patients using standardized psychometric instruments, to define factors associated with these psychological diseases, and to identify a potential healthcare gap. METHODS A total of 295 prosthetic eye wearers were screened using the 7-item generalized anxiety disorder scale (GAD-7) and the 9-item patient health questionnaire (PHQ-9). Scores of GAD-7 and PHQ-9 were correlated with scores of general physical and mental health functioning, vision-related quality of life, appearance-related distress, appearance-related social function, and further biosocial factors. RESULTS Five patients (2%) had a pre-diagnosed anxiety disorder, and 20 patients (7%) had a pre-diagnosed depression. However, our screening revealed 26 patients (9%) with anxiety symptoms, 31 patients (11%) with depression symptoms, and 40 patients (14%) suffering from both anxiety and depression symptoms. This underdiagnosing for both anxiety and depression disorders was significant (p < 0.001, respectively). Higher GAD-7 scores were significantly associated with higher PHQ-9 scores, lower appearance-related social function, lower mental health functioning, and female gender (p ≤ 0.021, respectively). Higher PHQ-9 scores were significantly associated with lower physical and mental health functioning, higher educational degree, and non-traumatic eye loss (p ≤ 0.038, respectively). CONCLUSIONS Anxiety and depression disorders seem to be underdiagnosed in prosthetic eye wearers and to have higher incidence compared with the general population. Therefore, a psychometric screening should be routinely implemented in the clinical care. For a successful long-term rehabilitation, integrated care by a multidisciplinary team including ophthalmic plastic surgeons, ophthalmologists, ocularists, general practitioners, and psychologists is essential.

Abstract
OBJECTIVES To explore the economic burden, prevalence of catastrophic healthcare expenditure (CHE) and the quality of life (QoL) of Chinese patients with visual impairment (VI) associated with eye diseases. DESIGN A questionnaire survey from March to May 2016 by structured face-to-face interviews of patients with VI. PARTICIPANTS 302 patients who were diagnosed with moderate VI or worse in both eyes (visual acuity <6/18) were included, and 298 patients (98.7%) who completed the survey questionnaires were eligible for the study. OUTCOME MEASURES The economic burden was estimated by calculating participants' direct costs covered in 2015 and the definition of CHE was out-of-pocket (OOP) costs exceeding 30% of annual household income. QoL was weighed by health utility value using time-trade-off valuation techniques. RESULTS Annual average direct costs per patient caused by VI were US$6988.6±US$10 834.3, and 70.3% were direct medical costs of which only 26.9% were reimbursable by medical insurance. 32.2% of households that suffered from CHE, in particular, were less wealthy patients with VI living in rural areas and without medical insurance. The health utility value was rated at 0.65 on average, and patients with VI aged 51-57, living alone and insured by commercial medical insurance had relatively less QoL. CONCLUSION Our study explored the economic burden and QoL of VI associated with patients with eye diseases in China, indicating a substantial economic burden and poor QoL. Preferential medical insurance policies should be designed in relation to people with VI to further reduce the health inequalities, avoid CHE and promote QoL.

Abstract
PURPOSE To investigate the prevalence and incidence of myopic choroidal neovascularization (CNV) in Taiwan, including the health care utilization and treatment-associated costs. METHODS A retrospective cohort study using existing data from the Taiwanese National Health Insurance claims database to identify patients who had a diagnosis of myopic CNV recorded from 1 January 2009 to 31 December 2011. The prevalence of myopic CNV was monitored during this period, and the frequency and cost of both treatment visits and monitoring visits were analyzed for 2 years following diagnosis. RESULTS The prevalence of myopic CNV was 0.017%. In total, 9068 patients with myopic CNV were identified, 12.3% (n = 1111) of whom were treated. Of those treated, 72.0% (n = 800) received intravitreal anti-vascular endothelial growth factor injections (IVI); the remainder received either photodynamic therapy with verteporfin (vPDT), laser photocoagulation, or a combination of therapies. IVI was associated with the largest number of treatment visits as well as a higher administrative (non-drug) cost per treatment visit (a mean of USD 57.18). vPDT alone was associated with a higher overall cost per treatment visit and more monitoring visits than IVI or laser photocoagulation. Costs for monitoring visits were highest for IVI. CONCLUSIONS The prevalence of myopic CNV was lower than that reported in previous studies, possibly because of differences in age distribution in the populations studied. The frequencies of treatment administered were similar to those reported in previous studies; however, a cost-effectiveness comparison could not be made owing to lack of data in previous studies.

Abstract
BACKGROUND/AIMS The Mycotic Ulcer Treatment Trial I (MUTT I) was a double-masked, multicentre, randomised controlled trial, which found that topical natamycin is superior to voriconazole for the treatment of filamentous fungal corneal ulcers. In this study, we determine risk factors for low vision-related quality of life in patients with fungal keratitis. METHODS The Indian visual function questionnaire (IND-VFQ) was administered to MUTT I study participants at 3 months. Associations between patient and ulcer characteristics and IND-VFQ subscale score were assessed using generalised estimating equations. RESULTS 323 patients were enrolled in the trial, and 292 (90.4%) completed the IND-VFQ at 3 months. Out of a total possible score of 100, the average VFQ score for all participants was 81.3 (range 0-100, SD 23.6). After correcting for treatment arm, each logMAR line of worse baseline visual acuity in the affected eye resulted in an average 1.2 points decrease on VFQ at 3 months (95% CI -1.8 to 0.6, p<0.001). Those who required therapeutic penetrating keratoplasty had an average of 25.2 points decrease on VFQ after correcting for treatment arm (95% CI -31.8 to -18.5, p<0.001). Study participants who were unemployed had on average 28.5 points decrease on VFQ (95% CI -46.9 to -10.2, p=0.002) after correcting for treatment arm. CONCLUSIONS Monocular vision loss from corneal opacity due to fungal keratitis reduced vision-related quality of life. Given the relatively high worldwide burden of corneal opacity, improving treatment outcomes of corneal infections should be a public health priority.

Abstract
Diabetic retinopathy may induce visual impairment. We evaluated vision-related quality of life in patients with visual acuity <5/10 in the better eye induced by retinopathy using the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25). The NEI VFQ-25 was self-administered to 196 patients in 3 Italian centres (A, B and C; n = 64, 61 and 71, respectively) dedicated to DR screening and treatment. Patients in the 3 centres did not differ by age, gender, occupation and diabetes duration. Multivariate analysis demonstrated that reduced visual acuity was associated with decreased scores for General Vision, Near Activities, Distance Activities, Visual-Specific Social Functioning, Mental Health, Role Difficulties and Dependency, Driving, Colour Vision and Peripheral Vision (p < 0.01, all). Treatment by photocoagulation was associated with reduced scores in General Health (-8.3; p = 0.002), General Vision (-7.2; p = 0.001), Visual-Specific Role Difficulties (-8.8; p = 0.015) and Driving (-13.7; p = 0.003). Centre affiliation was associated with different scores for General Health, Ocular pain, Distance Activities, Visual-Specific Social Functioning and Role Difficulties and Peripheral Vision. Women had higher scores for General Vision (p = 0.015), Near Activities (p = 0.005), Distance Activities (p = 0.006), Visual-Specific Social Functioning (p = 0.03), Visual-Specific Mental Health (p = 0.035) and Colour Vision (p = 0.012). Diabetic retinopathy and vision loss modify the way people perceive their own ability to function autonomously. More data should be collected to confirm this interpretation and to guide the development of more appropriate settings to improve approach and support to patients.

Abstract
OBJECTIVES Visual impairment and blindness (VI&B) cause a considerable and increasing economic burden in all high-income countries due to population ageing. Thus, we conducted a review of the literature to better understand all relevant costs associated with VI&B and to develop a multiperspective overview. DESIGN Systematic review: Two independent reviewers searched the relevant literature and assessed the studies for inclusion and exclusion criteria as well as quality. ELIGIBILITY CRITERIA FOR INCLUDED STUDIES Interventional, non-interventional and cost of illness studies, conducted prior to May 2012, investigating direct and indirect costs as well as intangible effects related to visual impairment and blindness were included. METHODS We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement approach to identify the relevant studies. A meta-analysis was not performed due to the variability of the reported cost categories and varying definition of visual impairment. RESULTS A total of 22 studies were included. Hospitalisation and use of medical services around diagnosis and treatment at the onset of VI&B were the largest contributor to direct medical costs. The mean annual expenses per patient were found to be US$ purchasing power parities (PPP) 12 175-14 029 for moderate visual impairment, US$ PPP 13 154-16 321 for severe visual impairment and US$ PPP 14 882-24 180 for blindness, almost twofold the costs for non-blind patients. Informal care was the major contributor to other direct costs, with the time spent by caregivers increasing from 5.8 h/week (or US$ PPP 263) for persons with vision >20/32 up to 94.1 h/week (or US$ PPP 55 062) for persons with vision ≤20/250. VI&B caused considerable indirect costs due to productivity losses, premature mortality and dead-weight losses. CONCLUSIONS VI&B cause a considerable economic burden for affected persons, their caregivers and society at large, which increases with the degree of visual impairment. This review provides insight into the distribution of costs and the economic impact of VI&B.

Abstract
INTRODUCTION Glaucoma is one of the leading causes of irreversible blindness worldwide and can have a significant impact on patient quality of life and vision-related functioning. The Glaucoma Quality of Life 15 (GQL-15) questionnaire is a disease-specific instrument to evaluate and quantify functional impairment of patients with glaucoma. This study evaluated the German version of the GQL-15 including correlations with perimetric parameters. METHODS A German version of the GQL-15 containing 15 items was developed and evaluated in 98 patients with glaucoma in different stages of the disease. The GQL-15 results were correlated with the perimetric parameters mean deviation (MD) and pattern standard deviation (PSD) of the better and worse eye. Classical and probabilistic test analyses (Rasch model) were performed. RESULTS The mean GQL-15 value was 77.3 ± 21.7 (SD) and most items of the GQL-15 correlated significantly with the MD of the worse eye (r = -0.416; p = 0.0014) and the better eye (r = -0.304; p = 0.02). There was also a highly significant correlation between glaucoma-specific QoL and visual acuity. A short version containing nine items yielding a higher psychometric performance can also be used. CONCLUSIONS The German version of the GQL-15 is a potent instrument to evaluate impairment in vision-specific functioning of patients with glaucoma. The GQL-15 values are better correlated with the sensitivity of the eye with the more severe glaucomatous damage. The data can help for a better understanding of individual patient impairment to improve medical advice and therapy of patients with glaucoma.
