RESUMEN

PURPOSE: To determine the cost effectiveness of an adjunctive screening OCT during the preoperative evaluation of a patient considering cataract surgery with a multifocal intraocular lens (IOL) implantation. DESIGN: Cost-effectiveness analysis. PARTICIPANTS: A 67-year-old man with 20/60 vision undergoing evaluation for first-eye cataract surgery. METHODS: The cost-effectiveness analysis of the reference patient undergoing a preoperative cataract examination with and without a screening OCT was performed, evaluating for vitreoretinal diseases including an epiretinal membrane, age-related macular degeneration, vitreomacular traction, and cystoid macular edema. It was assumed that patients with macular pathologies detected before surgery would receive a monofocal IOL and be referred to a retina specialist for evaluation and management. The Medicare reimbursable cost of an OCT was $41.81. All costs and benefits were adjusted for inflation to 2019 United States dollars and discounted 3% per annum over a 16-year time horizon. Probability sensitivity analyses and 1-way deterministic sensitivity analyses were performed to assess for uncertainty. MAIN OUTCOME MEASURES: Incremental cost-effectiveness ratio and incremental cost-utility ratio (ICUR) measured in quality-adjusted life years (QALYs). RESULTS: Approximately 20.5% of patients undergoing cataract surgery may have macular pathologies, of which 11% may not be detected on the initial clinical examination. In the base case, an adjunctive preoperative OCT was cost effective from a third-party payer and societal perspective in the United States. In the probability sensitivity analyses, the ICURs were within the societal willingness-to-pay threshold of $50 000/QALY in approximately 64.4% of the clinical scenarios. CONCLUSIONS: A preoperative screening OCT during the evaluation of a patient considering a multifocal IOL added to the costs of the cataract surgery, but the OCT increased the detection of macular pathologies and improved the QALYs over time. An adjunctive screening OCT can be cost effective from a third-party payer and societal perspective.

RESUMEN

PURPOSE: To assess the comparative efficacy and the long-term cost-utility of alternative minimally invasive glaucoma surgeries (MIGSs) when combined with cataract surgery in patients with primary open-angle glaucoma (POAG). METHODS: Treatment effects, as measured by the 1-year reduction in intraocular pressure (IOP), were estimated with an adjusted indirect treatment comparison. Evidence from randomized clinical trials was identified for four different MIGS methods. A disease-transition model was developed by capturing clinically relevant POAG stages and the expected natural disease evolution. Outcomes of the disease-transition model were the comparative utility [quality-adjusted life years (QALYs)], cost and cost-utility of included strategies in a lifetime horizon. RESULTS: Estimated 1-year IOP reductions were: cataract surgery - 2.05 mmHg (95% CI - 3.38; - 0.72), one trabecular micro-bypass stent - 3.15 mmHg (95% CI - 5.66; - 0.64), two trabecular micro-bypass stents - 4.85 mmHg (95% CI - 7.71; - 1.99) and intracanalicular scaffold - 2.25 mmHg (95% CI - 4.87; 0.37). Discounted outcomes from the disease-transition model appraised the strategy of two trabecular micro-bypass stents with cataract surgery in the moderate POAG stage as the one providing the greatest added value, with 10,955€ per additional QALY. Improved outcomes were seen when assessing MIGS in the moderate POAG stage. CONCLUSIONS: When indirectly comparing alternative MIGS methods combined with cataract surgery, the option of two trabecular micro-bypass stents showed both a superior efficacy and long-term cost-utility from a German perspective. Moreover, outcomes of the disease-transition model suggest POAG patients to beneficiate the most from an earlier intervention in the moderate stage contrary to waiting until an advanced disease is present.

RESUMEN

BACKGROUND: The number of people affected by cataract in the United Kingdom (UK) is growing rapidly due to ageing population. As the only way to treat cataract is through surgery, there is a high demand for this type of surgery and figures indicate that it is the most performed type of surgery in the UK. The National Health Service (NHS), which provides free of charge care in the UK, is under huge financial pressure due to budget austerity in the last decade. As the number of people affected by the disease is expected to grow significantly in coming years, the aim of this study is to evaluate whether the introduction of new processes and medical technologies will enable cataract services to cope with the demand within the NHS funding constraints. METHODS: We developed a Discrete Event Simulation model representing the cataract services pathways at Leicester Royal Infirmary Hospital. The model was inputted with data from national and local sources as well as from a surgery demand forecasting model developed in the study. The model was verified and validated with the participation of the cataract services clinical and management teams. RESULTS: Four scenarios involving increased number of surgeries per half-day surgery theatre slot were simulated. Results indicate that the total number of surgeries per year could be increased by 40% at no extra cost. However, the rate of improvement decreases for increased number of surgeries per half-day surgery theatre slot due to a higher number of cancelled surgeries. Productivity is expected to improve as the total number of doctors and nurses hours will increase by 5 and 12% respectively. However, non-human resources such as pre-surgery rooms and post-surgery recovery chairs are under-utilized across all scenarios. CONCLUSIONS: Using new processes and medical technologies for cataract surgery is a promising way to deal with the expected higher demand especially as this could be achieved with limited impact on costs. Non-human resources capacity need to be evenly levelled across the surgery pathway to improve their utilisation. The performance of cataract services could be improved by better communication with and proactive management of patients.

RESUMEN

BACKGROUND: Swedish Health and Medical Services act states that good care should be given to the entire population on equal terms. Still studies show that access to care in Sweden differ related to for example gender and socioeconomic variables. One of the areas in Swedish health care that has attracted attention for potential inequity in access is Cataract Extraction (CE). Previous studies of access to CE in Sweden show that female patients have in general poorer vision before they are operated and longer waiting times for CE than male patients. The aim of the study was to describe the waiting times in different patient groups with regards to visual acuity, gender, age, native country, educational level, annual income and whether the patient was retired or still working. METHODS: The study was designed as a register study of 102 532 patients who have had CE performed in Sweden 2010-2011. Linear regression was used to analyse the association between patient characteristics and waiting times. Mean waiting times for women and men were calculated for all groups. RESULTS: At significance level p < 0.05 longer waiting times corresponded to patients having good visual acuity, being of female gender, high age, retired, born outside the Nordic countries and having low income and education. Calculations of mean waiting times for all groups showed that women had longer waiting times than men. CONCLUSIONS: The differences between groups defined, for example, by gender, age, native country, income, education and retirement are statistically significant. We do not consider them as clinically significant, but we consider the consistent pattern that we have found noteworthy in relation to the principle of equity in health care.

RESUMEN

PURPOSE OF REVIEW: This article raises awareness about the cost-effectiveness and carbon footprint of various cataract surgery techniques, comparing their relative carbon emissions and expenses: manual small-incision cataract surgery (MSICS), phacoemulsification, and femtosecond laser-assisted cataract surgery. RECENT FINDINGS: As the most commonly performed surgical procedure worldwide, cataract surgery contributes significantly to global climate change. The carbon footprint of a single phacoemulsification cataract surgery is estimated to be comparable to that of a typical person's life for 1 week. Phacoemulsification has been estimated to be between 1.4 and 4.7 times more expensive than MSICS; however, given the lower degree of postoperative astigmatism and other potential complications, phacoemulsification may still be preferable to MSICS in relatively resource-rich settings requiring high levels of visual function. Limited data are currently available regarding the environmental and financial impact of femtosecond laser-assisted cataract surgery; however, in its current form, it appears to be the least cost-effective option. SUMMARY: Cataract surgery has a high value to patients. The relative environmental impact and cost of different types of cataract surgery should be considered as this treatment becomes even more broadly available globally and as new technologies are developed and implemented.

RESUMEN

PURPOSE OF REVIEW: Femtosecond lasers for use during cataract surgery carry significant purchase and use costs. The aim of this article is to help surgeons and surgery centers anticipate financial issues related to implementing femtosecond laser-assisted cataract surgery (FLACS). Such scenarios hopefully can help to inform decision making around the purchase and use of these lasers. RECENT FINDINGS: FLACS has several potential advantages over traditional phacoemulsification. However, although studies have demonstrated noninferiority of FLACS, there continues to be few data to support significantly improved visual outcomes. The literature does show a significantly higher cost for FLACS. As this cost can be passed on to patients under Medicare rules, there is the potential for increased physician revenue, which can be a motivator for adoption of this new technology. The magnitude of this increase is heavily influenced by the financial details of the implementation, like the cost of the laser, the volume of surgery performed, and the incremental increase in revenue. SUMMARY: A financial analysis should be performed prior to purchasing a femtosecond laser. This analysis can help predict if FLACS is going to be a financial windfall or a money loser.

RESUMEN

PURPOSE: To explore the cost-utility of cataract surgery in patients with advanced age-related macular degeneration (AMD). METHODS: Patients who were diagnosed as having and treated for age-related cataract and with a history of advanced AMD at the Department of Ophthalmology, Shanghai General Hospital, Shanghai Jiao Tong University, were included in the study. All of the participants underwent successful phacoemulsification with foldable posterior chamber intraocular lens implantation under retrobulbar anesthesia. Best-corrected visual acuity (BCVA) and utility value elicited by time trade-off method from patients at 3-month postoperative time were compared with those before surgery. Quality-adjusted life years (QALYs) gained in a lifetime were calculated at a 3% annual discounted rate. Costs per QALY gained were calculated using the bootstrap method, and probabilities of being cost-effective were presented using a cost-effectiveness acceptability curve. Sensitivity analyses were performed to test the robustness of the results. RESULTS: Mean logarithm of the minimum angle of resolution BCVA in the operated eye increased from 1.37 ± 0.5 (Snellen, 20/469) to 0.98 ± 0.25 (Snellen, 20/191) (p < 0.001); BCVA in the weighted average from both eyes (=75% better eye + 25% worse eye) was changed from 1.13 ± 0.22 (Snellen, 20/270) to 0.96 ± 0.17 (Snellen, 20/182) (p < 0.001). Utility values from both patients and doctors increased significantly after surgery (p < 0.001 and p = 0.007). Patients gained 1.17 QALYs by cataract surgery in their lifetime. The cost per QALY was 8835 Chinese yuan (CNY) (1400 U.S. dollars [USD]). It is cost-effective at the threshold of 115,062 CNY (18,235 USD) per QALY in China recommended by the World Health Organization. The cost per QALY varied from 7045 CNY (1116 USD) to 94,178 CNY (14,925 USD) in sensitivity analyses. CONCLUSIONS: Visual acuity and quality of life assessed by utility value improved significantly after surgery. Cataract surgery was a cost-effective intervention for patients with coexistent AMD.

RESUMEN

Because of expanding indications and improvements in supportive care, the utilization of blood and marrow cell transplantation (BMT) to treat various conditions is increasing exponentially, and currently more than 60,000 BMTs are performed annually worldwide. By the year 2030, it is projected that the number of BMT survivors will increase 5-fold, potentially resulting in one half of a million survivors in the United States alone. As the majority of survivors now live beyond the first 2 years after BMT, they are prone to a unique set of complications and late effects. Until recently, BMT experts assumed responsibility for almost all of the care for these survivors, but now oncologists/hematologists, pediatricians, and internists are involved frequently in offering specialized care and preventive services to these survivors. To integrate and translate into clinical practice the unique BMT survivorship issues with current preventive guidelines, a team effort is required. This can be facilitated by a dedicated "long-term-follow-up (LTFU)" clinic that provides lifelong care for BMT survivors. In this review, we first illustrate with clinical vignettes the need for LTFU and then focus upon the following: (1) types of LTFU clinic models, (2) challenges and possible solutions to the establishment of LTFU clinic, and (3) vulnerable transition periods.

RESUMEN

AIMS: To develop a health economic model to evaluate the cost-effectiveness of new interventions for Type 1 diabetes mellitus by their effects on long-term complications (measured through mean HbA1c ) while capturing the impact of treatment on hypoglycaemic events. METHODS: Through a systematic review, we identified complications associated with Type 1 diabetes mellitus and data describing the long-term incidence of these complications. An individual patient simulation model was developed and included the following complications: cardiovascular disease, peripheral neuropathy, microalbuminuria, end-stage renal disease, proliferative retinopathy, ketoacidosis, cataract, hypoglycemia and adverse birth outcomes. Risk equations were developed from published cumulative incidence data and hazard ratios for the effect of HbA1c , age and duration of diabetes. We validated the model by comparing model predictions with observed outcomes from studies used to build the model (internal validation) and from other published data (external validation). We performed illustrative analyses for typical patient cohorts and a hypothetical intervention. RESULTS: Model predictions were within 2% of expected values in the internal validation and within 8% of observed values in the external validation (percentages represent absolute differences in the cumulative incidence). CONCLUSIONS: The model utilized high-quality, recent data specific to people with Type 1 diabetes mellitus. In the model validation, results deviated less than 8% from expected values.

RESUMEN

PURPOSE OF REVIEW: To review the literature and create a concise evaluation and comment on the ways to provide financially efficient cataract surgery in a healthcare environment that produces significant challenges to providing care, while maintaining quality outcomes, safety, patient satisfaction, and employee satisfaction. RECENT FINDINGS: The recent reductions in reimbursement for cataract surgery have fueled an increased need to drive innovation in ways to be more financially efficient. At the same time, new technology in the field, especially as it relates to use of the femtosecond laser for portions of lens surgery, has increased the challenges in creating an efficient and cost-effective structure for providing care. SUMMARY: Cataract surgery is one of the most beneficial procedures for a patient's quality of life, and is one of the most common surgical procedures performed. At the same time, the current cost-effectiveness is quite high, and yet there are still ways to become more financially efficient in many centers providing cataract care.

RESUMEN

BACKGROUND: Elective cataract surgery is the most commonly performed surgical procedure in developed countries. However, it is unclear whether cataract surgery on the second eye provides enough incremental benefit to be considered cost-effective. This study conducted a cost-effectiveness analysis of second-eye cataract surgery in the U.K. DESIGN: A cost-effectiveness analysis. METHODS: A decision-analytical model was developed to estimate the cost-effectiveness of second-eye cataract surgery, based on a comprehensive epidemiological and economic review to develop the parameters for the model. The model followed the clinical pathway of cohorts of patients receiving second-eye cataract surgery and included costs and health benefits associated with post-surgical complications. RESULTS: In the model, second-eye surgery generated 0.68 additional quality-adjusted life years (QALY) with an incremental cost-effectiveness ratio of £1,964 per QALY gained. In sensitivity analyses, model results were most sensitive to changes in the health-related quality of life (HRQoL) gain associated with second-eye surgery, but otherwise robust to changes in parameter values. The probability that second-eye surgery is cost-effective at willingness to pay thresholds of £10,000 and £20,000 was 100%. CONCLUSION: Second-eye cataract surgery is generally cost-effective based on the best available data and under most assumptions. However, there are only a small number of clinical trials for second-eye cataract surgery, and these have not been conducted in recent years.

RESUMEN

The 2011 International Commission on Radiological Protection (ICRP) statement on tissue reactions suggested a significant reduction in the threshold dose for radiation induced cataracts. This, combined with the potential for a long delay between exposure and cataract diagnosis, may result in an increased requirement to evaluate eye dose from past exposures in order to settle current compensation claims. This article highlights how compensation claims relating to radiation exposure are assessed within the UK legal system and suggests that in vivo Electro Paramagnetic Resonance (EPR) dosimetry of teeth has utility for the retrospective quantification of radiation doses to the eye. It was identified that in vivo EPR in its current form may be sufficiently sensitive to support cataract compensation claims, although further work is required to enable appropriate dose conversion coefficients to be quantified.

RESUMEN

PURPOSE: To perform a comparative cost-effectiveness analysis (CEA) of femtosecond laser-assisted cataract surgery (LCS) and conventional phacoemulsification cataract surgery (PCS) DESIGN: Retrospective CEA using computer-based econometric modeling. PARTICIPANTS: Hypothetical cohort of patients undergoing cataract surgery in the better eye based on a review of the current literature and our direct experience using LCS. METHODS: A cost-effectiveness decision tree model was constructed to analyze the cost-effectiveness of LCS compared with PCS. Complication rates of cataract surgery were obtained from a review of the current literature to complete the cohort of patients and outcomes. This data was incorporated with time trade-off utility values converted from visual acuity outcomes. MAIN OUTCOME MEASURES: Improvements in best-corrected visual acuity obtained from the literature were used to calculate the increase in quality-adjusted life-years (QALYs) in a hypothetical cohort between 6 months and 1 year after cataract surgery. This was combined with approximate costs in a cost-utility analysis model to determine the incremental cost-effectiveness ratios (ICERs). RESULTS: Based on the simulated complication rates of PCS and LCS and assuming resultant visual acuity outcome improvement of 5% in uncomplicated cases of LCS, the cost-effectiveness (dollars spent per QALY) gained from LCS was not cost-effective at $92 862 Australian Dollars. The total QALY gain for LCS over PCS was 0.06 units. Multivariate sensitivity analyses revealed that LCS would need to significantly improve visual outcomes and complications rates over PCS, along with a reduction in cost to patient, to improve cost effectiveness. Modeling a best-case scenario of LCS with excellent visual outcomes (100%), a significant reduction in complications (0%) and a significantly reduced cost to patient (of $300) resulted in an ICER of $20 000. CONCLUSIONS: Laser cataract surgery, irrespective of potential improvements in visual acuity outcomes and complication rates, is not cost effective at its current cost to patient when compared with cost-effectiveness benchmarks and other medical interventions, including PCS. A significant reduction in the cost to patient (via reduced consumable/click cost) would increase the likelihood of LCS being considered cost effective.

RESUMEN

PURPOSE: To measure the change in quality of life and economic circumstances after cataract surgery and identify the predictors of an improvement in these outcomes. DESIGN: A multicenter, prospective, longitudinal cohort study. PARTICIPANTS: Participants aged 18 years were recruited to the study if the clinical assessment of their best uncorrected vision was <= 6/18 in the better eye because of cataract [Corrected]. METHODS: Cataract surgery. MAIN OUTCOME MEASURES: Data were collected on quality of life and a multidimensional assessment of household economic circumstances (work status, income, asset ownership, household economic hardship, and catastrophic health expenditure). RESULTS: At 12 months follow-up, 381 of 480 participants were re-interviewed, and all had undergone surgery. There was a significant improvement in quality of life. Household economic circumstances also improved (mean change paid work participation/month: 44.5 hours, P < 0.0001; mean change unpaid work participation/month: 89.5 hours, P < 0.0001; change in proportion with hardship: -17%, P < 0.0001; and change in proportion with catastrophic health expenditure: -7%, P = 0.02). Improvements were most likely in near-poor households and were related to the type of surgery and complications after surgery. CONCLUSIONS: This research showed that cataract surgery is associated with meaningful improvements in quality of life and household economic circumstances that are indicative of positive transitions out of poverty. Given the unmet need for cataract surgery in low- and middle-income countries where cataract impairment is substantial, this research demonstrates the potential of a relatively simple, low-cost health intervention to greatly improve household economic circumstances.

RESUMEN

Economic evaluations are tools for assessing emerging technologies and a complement for decision-making in healthcare systems. However, this topic may not be familiar for doctors and academics, who may be confused when interpreting the results of studies using these tools. Cataract is a disease which has received special attention in healthcare systems due to its high incidence, the great impact that it could have on patients' quality of life, and the fact that it can be definitively solved in almost all cases through cataract surgery. Historically, economic evaluations in cataract surgery have been conducted for many purposes by simply assessing whether the surgery is cost-effective for specific questions related to the implantation of multifocal intraocular lenses, surgical techniques, optimizing assessments, preventing diseases or complications, etc. Moreover, although there are systematic reviews about cataract surgery and narrative reviews introducing the concept of economic evaluations, as far as we know, no previous study has been conducted that synthesizes and integrates evidence coming from both fields. Thus, the purpose of this narrative review is to introduce doctors and academics to economic evaluation tools, to describe how these have been historically applied to cataract surgery, and to provide special considerations for the correct interpretation of economic studies.

RESUMEN

Objective: To investigate the prevalence of cataract-induced visual disability and its association with individual-level socioeconomic status (SES) among older adults in China. Methods: Using the data of 354,743 older adults (60 years and older) from the Second China National Sample Survey on Disability in 2006. Cross-sectional study design was applied. The differences in visual disability prevalence of cataracts among sociodemographic subgroups were analyzed by the chi-square test, and the association between individual-level SES and cataract-induced visual disability was investigated by the multivariate logistic regression model. Results: The weighted visual disability prevalence of cataracts was 4.84% in 2006. Older people with a higher household income per capita (OR = 0.83, 95% CI: 0.81-0.85), higher education level (primary school vs. illiteracy: OR = 0.80, 95% CI: 0.76-0.83; ≥undergraduate college vs. illiteracy: OR = 0.31, 95% CI: 0.25-0.39), and occupation (OR = 0.53, 95% CI: 0.50-0.56) were less likely to suffer from cataract-induced visual disability. Household income per capita and education level increase played a greater role in decreasing the risk of visual disability caused by cataracts in urban areas, while having occupation contributed more to reducing the risk of disability in rural areas. Conclusion: The gap in individual-level SES is closely related to the visual health inequities among older Chinese people and there are two distinct mechanisms in rural and urban areas. Strategies to promote collaborative healthcare development regionally, strengthen safeguards for disadvantaged groups, and increase public awareness of visual disability prevention are warranted.

RESUMEN

Utilization of digital technologies for cataract screening in primary care is a potential solution for addressing the dilemma between the growing aging population and unequally distributed resources. Here, we propose a digital technology-driven hierarchical screening (DH screening) pattern implemented in China to promote the equity and accessibility of healthcare. It consists of home-based mobile artificial intelligence (AI) screening, community-based AI diagnosis, and referral to hospitals. We utilize decision-analytic Markov models to evaluate the cost-effectiveness and cost-utility of different cataract screening strategies (no screening, telescreening, AI screening and DH screening). A simulated cohort of 100,000 individuals from age 50 is built through a total of 30 1-year Markov cycles. The primary outcomes are incremental cost-effectiveness ratio and incremental cost-utility ratio. The results show that DH screening dominates no screening, telescreening and AI screening in urban and rural China. Annual DH screening emerges as the most economically effective strategy with 341 (338 to 344) and 1326 (1312 to 1340) years of blindness avoided compared with telescreening, and 37 (35 to 39) and 140 (131 to 148) years compared with AI screening in urban and rural settings, respectively. The findings remain robust across all sensitivity analyses conducted. Here, we report that DH screening is cost-effective in urban and rural China, and the annual screening proves to be the most cost-effective option, providing an economic rationale for policymakers promoting public eye health in low- and middle-income countries.

RESUMEN

OBJECTIVE: To assess the 2012 cost utility of cataract surgery in the United States and to compare 2012 cost-utility data with those from 2000. DESIGN: Value-Based Medicine (Flourtown, PA), patient preference-based, comparative effectiveness analysis and cost-utility analysis using 2012 real United States dollars. PARTICIPANTS: Previously published Patient Outcomes Research Team Study data and time tradeoff utilities obtained from patients with vision loss. Visual acuity measurements from patients wtih untreated cataract were used as controls. INTERVENTION: Thirteen-year, average, first-eye and second-eye cataract surgery cost-utility analysis using the societal and third-party insurer cost perspectives. MAIN OUTCOME MEASURES: Patient value gain in quality-adjusted life years (QALYs) and percent gain in quality of life as well as the cost-utility ratio using the dollars expended per QALY gained. Patient and financial value outcomes were discounted at 3% annually with net present value analysis. RESULTS: First-eye cataract surgery conferred 1.6212 QALYs over the 13-year model, a 20.8% quality-of-life gain. Bilateral cataract surgery conferred 2.8152 QALYs over 13 years, a 36.2% improvement in quality of life. The direct ophthalmic medical cost for unilateral cataract surgery in 2012 United States nominal dollars was $2653, an inflation-adjusted 34.2% less than in 2000 and 85% less than in 1985. The 2012 inflation-adjusted physician fee was 10.1% of that in 1985. The 13-year societal cost perspective, financial return on investment (ROI) for first-eye cataract surgery was $121,198, a 4567% gain. The third-party insurer cost perspective average cost-utility ratio was $2653/1.6212 = $1636/QALY for unilateral cataract surgery, whereas the societal cost perspective average cost-utility ratio was -$121,198/1.6212 = -$74,759/QALY. The net 13-year $123.4-billion financial ROI from a 1-year cohort of cataract surgery patients was accrued: Medicare, $36.4 billion; Medicaid, $3.3 billion; other insurers, $9.6 billion; patients, $48.6 billion; and increased United States national productivity, $25.4 billion. CONCLUSIONS: Cataract surgery in 2012 greatly improved quality of life and was highly cost effective. It was 34.4% less expensive than in 2000 and 85% less expensive than in 1985. Initial cataract surgery yielded an extraordinary 4567% financial ROI to society over the 13-year model.

RESUMEN

PURPOSE OF REVIEW: As the elderly population continues to grow in the USA, an understanding of the increasing burden of cataract is pivotal. This review seeks to iterate the presence of this burden and to understand it better in the context of race, sex, and socioeconomic factors. RECENT FINDINGS: Although there have been multiple prevalence studies addressing the cataract burden in the USA, updated literature that directly elucidates the above issues has been sparse. Recent data support previous findings that the cataract burden among women is greater than that of men, likely predominantly due to greater longevity. With regard to race, there appears to be a slightly increased burden among Whites, although this increase may show regional variability and change over the next few decades, especially as the presently young Hispanic population continues to age and grow. It is likely that the significant divider responsible for unmet cataract surgery is socioeconomic, due to such factors as insurance coverage, income, and barriers to access such as transportation, service accessibility, and awareness. These latter barriers of income and access appear to be identical to those identified in developing countries. SUMMARY: The cataract burden in the USA is significant and is expected to continue to grow. Further studies are warranted to help us better understand barriers to access, particularly with regard to race and socioeconomic factors. Local efforts to address education and logistical barriers as well as nationwide policy efforts to address insurance coverage appear to be a crucial factor in surmounting an ongoing but treatable chronic disease.

RESUMEN

OBJECTIVE: To describe the effect of the Fund against Catastrophic Expenditures in Health on the provision of services for patients with cataract. MATERIALS AND METHODS: We used administrative dataset on hospital discharges and official figures on population to estimate the rate of care and the coverage for cataract. To estimate the variation on resources, we used data from the National System of Health Information. RESULTS: Coverage for this disease had a significant increase between 2000 and 2010, passing from 24 per thousand cataract patients receiving attention to 58.8 per thousand. This growth is mainly due to the incorporation of cataract to the catalog of diseases covered by the Fund against Catastrophic Expenditures in Health, although this variation is not based on additional resources but in a higher productivity. The growth of services is noticeable in Aguascalientes, Coahuila, Distrito Federal and Nayarit. CONCLUSIONS: Our results suggest that policy-making based on evidence have actually brought benefits for Mexican population.
