Association between diagnosed diabetes and trouble seeing, National Health Interview Survey, 2011-13
Lipton BJ , Decker SL . J Diabetes 2015 7 (5) 743-6 Approximately 21 million individuals in the US have diagnosed diabetes.1 Diabetic retinopathy, a progressive condition that can ultimately lead to blindness, affects approximately 29% of adults aged 40 years and older with diabetes.2 Diabetes is also associated with an increased likelihood of other conditions that may affect vision, such as cataracts and glaucoma.3 We assessed the association between diagnosed diabetes and self-reported trouble seeing while controlling for other covariates that may affect vision. | | The present study used 2011–13 data from the National Health Interview Survey (NHIS).4 The NHIS is a nationally representative sample of US households, with one adult member of each family selected to complete a more in-depth survey. Final 2011–13 sample adult response rates ranged from 61% to 66%. Respondents were asked if they had trouble seeing even when wearing usual vision correction. Possible responses included “yes”, “no”, and “don’t know”, and were used to create a binary variable equal to one for those who did and zero for those who did not report trouble seeing (responses of “don’t know” and refusals [accounting for <0.01% of responses] were considered missing). Those who reported receiving a diabetes diagnosis from a healthcare provider were classified as having diabetes. The sample consisted of adults aged 25 years and older with complete demographic, comorbidity, vision, and diabetes information.5 |
The effect of health insurance coverage on medical care utilization and health outcomes: evidence from Medicaid adult vision benefits
Lipton BJ , Decker SL . J Health Econ 2015 44 320-32 Increasing the proportion of adults that have regular, comprehensive eye exams and reducing visual impairment due to uncorrected refractive error and other common eye health problems are federal health objectives. We examine the effect of vision insurance on eye care utilization and vision health outcomes by taking advantage of quasi-experimental variation in Medicaid coverage of adult vision care. Using a difference-in-difference-in-difference approach, we find that Medicaid beneficiaries with vision coverage are 4.4 percentage points (p<0.01) more likely to have seen an eye doctor in the past year, 5.3 percentage points (p<0.01) less likely to report needing but not purchasing eyeglasses or contacts due to cost, 2.0 percentage points (p<0.05) less likely to report difficulty seeing with usual vision correction, and 1.2 percentage points (p<0.01) less likely to have a functional limitation due to vision. |
The effect of Medicaid adult vision coverage on the likelihood of appropriate correction of distance vision: evidence from the National Health and Nutrition Examination Survey
Lipton BJ , Decker SL . Soc Sci Med 2015 150 258-67 BACKGROUND: Medicaid is the main public health insurance program for individuals with low income in the United States. Some state Medicaid programs cover preventive eye care services and vision correction, while others cover emergency eye care only. Similar to other optional benefits, states may add and drop adult vision benefits over time. RESEARCH OBJECTIVE: This article examines whether providing adult vision benefits is associated with an increase in the percentage of low-income individuals with appropriately corrected distance vision as measured during an eye exam. METHODOLOGY: We estimate the effect of Medicaid vision coverage on the likelihood of having appropriately corrected distance vision using examination data from the 2001-2008 National Health and Nutrition Examination Survey. We compare vision outcomes for Medicaid beneficiaries (n = 712) and other low income adults not enrolled in Medicaid (n = 4786) before and after changes to state vision coverage policies. FINDINGS: Between 29 and 33 states provided Medicaid adult vision benefits during 2001-2008, depending on the year. Our findings imply that Medicaid adult vision coverage is associated with a significant increase in the percentage of Medicaid beneficiaries with appropriately corrected distance vision of up to 10 percentage points. CONCLUSION: Providing vision coverage to adults on Medicaid significantly increases the likelihood of appropriate correction of distance vision. Further research on the impact of vision coverage on related functional outcomes and the effects of Medicaid coverage of other services may be appropriate. |
Do Medicaid benefit expansions have teeth? The effect of Medicaid adult dental coverage on the use of dental services and oral health
Decker SL , Lipton BJ . J Health Econ 2015 44 212-225 This article examines the effect of Medicaid adult dental coverage on use of dental care and dental health outcomes using state-level variation in dental coverage during 2000-2012. Our findings imply that dental coverage is associated with an increase in the likelihood of a recent dental visit, with the size of the effect increasing with Medicaid payment rates to dentists, and a reduction in the likelihood of untreated dental caries. We are among the first to detect an effect of Medicaid coverage on a clinical health outcome other than mortality. These findings may have implications for states expanding Medicaid coverage to adults with incomes of up to 138% of the federal poverty threshold under the Affordable Care Act as most of these states offer an adult dental benefit. |
ACA provisions associated with increase in percentage of young adult women initiating and completing the HPV vaccine
Lipton BJ , Decker SL . Health Aff (Millwood) 2015 34 (5) 757-64 Affordable Care Act provisions implemented in 2010 required insurance plans to offer dependent coverage to people ages 19-25 and to provide targeted preventive services with zero cost sharing. These provisions both increased the percentage of young adults with any source of health insurance coverage and improved the generosity of coverage. We examined how these provisions affected use of the human papillomavirus (HPV) vaccine, which is among the most expensive of recommended vaccines, among young adult women. Using 2008-12 data from the National Health Interview Survey, we estimated that the 2010 policy implementation increased the likelihood of HPV vaccine initiation and completion by 7.7 and 5.8 percentage points, respectively, for women ages 19-25 relative to a control group of women age 18 or 26. These estimates translate to approximately 1.1 million young women initiating and 854,000 young women completing the vaccine series. |
