Changes in Mental Health Following the 2016 Presidential Election.

BACKGROUND: The 2016 presidential election and the controversial policy agenda of its victor have raised concerns about how the election may have impacted mental health. OBJECTIVE: Assess how mental health changed from before to after the November 2016 election and how trends differed in states that voted for Donald Trump versus Hillary Clinton. DESIGN: Pre- versus post-election study using monthly cross-sectional survey data. PARTICIPANTS: A total of 499,201 adults surveyed in the Behavioral Risk Factor Surveillance System from May 2016 to May 2017. EXPOSURE: Residence in a state that voted for Trump versus state that voted for Clinton and the candidate's margin of victory in the state. MAIN MEASURES: Self-reported days of poor mental health in the last 30 days and depression rate. KEY RESULTS: Compared to October 2016, the mean days of poor mental health in the last 30 days per adult rose from 3.35 to 3.85 in December 2016 in Clinton states (0.50 days difference, p = 0.005) but remained statistically unchanged in Trump states, moving from 3.94 to 3.78 days (- 0.17 difference, p = 0.308). The rises in poor mental health days in Clinton states were driven by older adults, women, and white individuals. The depression rate in Clinton states began rising in January 2017. A 10-percentage point higher margin of victory for Clinton in a state predicted 0.41 more days of poor mental health per adult in December 2016 on average (p = 0.001). CONCLUSIONS: In states that voted for Clinton, there were 54.6 million more days of poor mental health among adults in December 2016, the month following the election, compared to October 2016. Clinicians should consider that elections could cause at least transitory increases in poor mental health and tailor patient care accordingly, especially with the 2020 election upon us.

Quality and Cost of Care by Hospital Teaching Status: What Are the Differences?

Policy Points In two respects, quality of care tends to be higher at major teaching hospitals: process of care and long-term survival of cancer patients following initial diagnosis. There is also evidence that short-term (30-day) mortality is lower on average at such hospitals, although the quality of evidence is somewhat lower. Quality of care is mulitdimensional. Empirical evidence by teaching status on dimensions other than survival is mixed. Higher Medicare payments for care provided by major teaching hospitals are partially offset by lower payments to nonhospital providers. Nevertheless, the payment differences between major teaching and nonteaching hospitals for hospital stays, especially for complex cases, potentially increase prices other insurers pay for hospital care. CONTEXT: The relative performance of teaching hospitals has been discussed for decades. For private and public insurers with provider networks, an issue is whether having a major teaching hospital in the network is a "must." For traditional fee-for-service Medicare, there is an issue of adequacy of payment of hospitals with various attributes, including graduate medical education (GME) provision. Much empirical evidence on relative quality and cost has been published. This paper aims to (1) evaluate empirical evidence on relative quality and cost of teaching hospitals and (2) assess what the findings indicate for public and private insurer policy. METHODS: Complementary approaches were used to select studies for review. (1) Relevant studies highly cited in Web of Science were selected. (2) This search led to studies cited by these studies as well as studies that cited these studies. (3) Several literature reviews were helpful in locating pertinent studies. Some policy-oriented papers were found in Google under topics to which the policy applied. (4) Several papers were added based on suggestions of reviewers. FINDINGS: Quality of care as measured in process of care studies and in longitudinal studies of long-term survival of cancer patients tends to be higher at major teaching hospitals. Evidence on survival at 30 days post admission for common conditions and procedures also tends to favor such hospitals. Findings on other dimensions of relative quality are mixed. Hospitals with a substantial commitment to graduate medical education, major teaching hospitals, are about 10% to 20% more costly than nonteaching hospitals. Private insurers pay a differential to major teaching hospitals at this range's lower end. Inclusive of subsidies, Medicare pays major teaching hospitals substantially more than 20% extra, especially for complex surgical procedures. CONCLUSIONS: Based on the evidence on quality, there is reason for patients to be willing to pay more for inclusion of major teaching hospitals in private insurer networks at least for some services. Medicare payment for GME has long been a controversial policy issue. The actual indirect cost of GME is likely to be far less than the amount Medicare is currently paying hospitals.

1918 Influenza Pandemic: In Utero Exposure in the United States and Long-Term Impact on Hospitalizations.

OBJECTIVES: To explore associations between in utero exposure to the 1918 influenza pandemic and hospitalization rates in old age (≥ 70 years) in the United States. METHODS: We identified individuals exposed (mild and deadly waves) and unexposed in utero to the 1918 influenza pandemic (a natural experiment) by using birth dates from the Asset and Health Dynamics Among the Oldest Old survey. We analyzed differences in hospitalization rates by exposure status with multivariate linear regression. RESULTS: In utero exposure to the deadly wave of the 1918 influenza pandemic increased the number of hospital visits by 10.0 per 100 persons. For those exposed in utero to the deadliest wave of the influenza pandemic, high rates of functional limitations are shown to drive the higher rates of hospitalizations in old age. CONCLUSIONS: In utero exposure to the influenza pandemic increased functional limitations and hospitalization rates in old age. Public Health Implications. To determine investments in influenza pandemic prevention programs that protect fetal health, policymakers should include long-term reductions in hospitalizations in their cost-benefit evaluations.

Alcohol-Impaired Driving and Perceived Risks of Legal Consequences.

BACKGROUND: Driving while impaired (DWI) is a threat to public health. Codified legal sanctions are a widely implemented strategy to reduce DWI. However, it is unclear that sanctioning affects individual risk perceptions so as to deter alcohol-impaired driving. METHODS: Using survey data collected from individual drivers, police, and defense attorneys specializing in DWI in 8 U.S. cities, we investigated whether risk perceptions about legal consequences for alcohol-impaired driving, both the risk of being stopped if driving while alcohol-impaired and receiving specific penalties following a DWI, deter alcohol-impaired driving. First, we analyzed how different drivers' risk perceptions about being pulled over and facing criminal sanctions related to their self-reported alcohol-impaired driving in the year following the interview at which risk perceptions were elicited. Second, using data from an experimental module in which individual's risk perceptions were randomly updated by the interview, we analyzed how each driver's beliefs about his or her own future alcohol-impaired driving responded to randomly generated increases in the apprehension probability and sanction magnitude. RESULTS: Higher probabilities as estimated by the individuals of being pulled over corresponded to less alcohol-impaired driving in both analyses. Conversely, there was no statistical relationship between perceptions of criminal sanctions for DWI and alcohol-impaired driving with 1 exception-a small significant negative relationship between duration of jail time following a DWI conviction and alcohol-impaired driving. CONCLUSIONS: Perceptions regarding the threat of being apprehended for alcohol-impaired driving were related to actual self-reported driving, while perceived sanctions following a DWI conviction for DWI generally were unrelated to either actual self-reported alcohol-impaired driving or the person's estimate of probability that he or she would drive while alcohol-impaired in the following year. Increasing certainty of apprehension by increasing police staffing and/or conducting sobriety checks is a more effective strategy for reducing alcohol-impaired driving than legislating increased penalties for DWI.

Is Major Depression Linked to Alcohol-Impaired Driving?

BACKGROUND: Alcohol-impaired driving causes a substantial proportion of motor vehicle accidents. Depression is a prevalent psychiatric disorder among drinker-drivers. Few previous studies have investigated the relationship between major depression and alcohol-impaired driving. OBJECTIVES: We investigated whether depression has a positive relationship with the probability of alcohol-impaired driving after controlling for the co-occurrence of binge drinking and alcohol dependence. METHODS: Our data consisted of drinkers aged 21-64 years from two waves of the National Epidemiologic Survey of Alcohol and Related Conditions. Cross-sectional analysis investigated whether depression is an independent risk factor for drinking-driving. Longitudinal analysis distinguished the relationship of depression onset, continuance, and recovery with changes in drinking-driving behaviors between the waves. These dual approaches allowed comparisons with previous studies. RESULTS: Major depression was a small but statistically significant predictor of changes in alcohol-impaired driving behaviors among males but not females. Binge drinking and alcohol dependence were comparatively stronger predictors. Conclusions/Importance: There is limited empirical support that treating depression reduces drinking and driving in males who do not exhibit symptoms of alcohol use disorders. For persons with co-occurring depression and alcohol use disorders, depression treatment should be part of a strategy for treating alcohol use disorders which are highly related to drinking and driving.

Effect of Prior Anti-VEGF Injections on the Risk of Retained Lens Fragments and Endophthalmitis after Cataract Surgery in the Elderly.

PURPOSE: To investigate the effect of prior intravitreal anti-vascular endothelial growth factor (VEGF) injections on surgical and postoperative complication rates associated with cataract surgery in a nationally representative longitudinal sample of elderly persons. DESIGN: Retrospective, longitudinal cohort analysis. PARTICIPANTS: A total of 203 643 Medicare beneficiaries who underwent cataract surgery from January 1, 2009, to December 31, 2013. METHODS: By using the 5% sample of Medicare claims data, the study assessed risks of 3 adverse outcomes after receipt of cataract surgery for beneficiaries with a history of intravitreal injections. Risks of these outcomes in beneficiaries with a history of intravitreal injections relative to those without were calculated using the Cox proportional hazard model. MAIN OUTCOME MEASURES: The primary outcome was the risk of subsequent removal of retained lens fragments (RLFs) within 28 days after cataract surgery. Secondary outcomes were a new diagnosis of acute (<40 days) or delayed-onset (40+ days) endophthalmitis and risk of a new primary open-angle glaucoma (POAG) diagnosis within 365 days after cataract surgery. RESULTS: Prior intravitreal anti-VEGF injections were associated with a significantly increased risk of subsequent RLF removal within 28 days after cataract surgery (hazard ratio [HR], 2.26; 95% confidence interval [CI], 1.19-4.30). Prior injections were also associated with increased risk of both acute (HR, 2.29; 95% CI, 1.001-5.22) and delayed-onset endophthalmitis (HR, 3.65; 95% CI, 1.65-8.05). Prior injections were not a significant indicator of increased risk of a new POAG diagnosis. CONCLUSIONS: A history of intravitreal injections may be a risk factor for cataract surgery-related intraoperative complications and endophthalmitis. Given the frequency of intravitreal injections and cataract surgery, increased preoperative assessment, additional intraoperative caution, and postoperative vigilance are recommended in patients with a history of intravitreal injections undergoing cataract extraction.

Introducing Anti-Vascular Endothelial Growth Factor Therapies for AMD Did Not Raise Risk of Myocardial Infarction, Stroke, and Death.

PURPOSE: To assess the effect of availability of anti-vascular endothelial growth factor (VEGF) therapy on mortality and hospitalizations for acute myocardial infarction (AMI) and stroke over a 5-year follow-up period in United States Medicare beneficiaries newly diagnosed with exudative age-related macular degeneration (AMD) in 2006 compared with control groups consisting of beneficiaries (1) newly diagnosed with exudative AMD at a time when anti-VEGF therapy was not possible and (2) newly diagnosed with nonexudative AMD. DESIGN: Retrospective cohort study. PARTICIPANTS: Beneficiaries newly diagnosed with exudative and nonexudative AMD in 2000 and 2006 selected from a random longitudinal sample of Medicare 5% claims and enrollment files. METHODS: Beneficiaries with a first diagnosis of exudative AMD in 2006 were the treatment group; beneficiaries newly diagnosed with exudative AMD in 2000 or nonexudative AMD in 2000 or 2006 were control groups. To deal with potential selection bias, we designed an intent-to-treat study, which controlled for nonadherence to prescribed regimens. The treatment group consisted of patients with clinically appropriate characteristics to receive anti-VEGF injections given that the therapy is available, bypassing the need to monitor whether treatment was actually received. Control groups consisted of patients with clinically appropriate characteristics but first diagnosed at a time when the therapy was unavailable (2000) and similar patients but for whom the therapy was not clinically indicated (2000, 2006). We used a Cox proportional hazard model. MAIN OUTCOME MEASURES: All-cause mortality and hospitalization for AMI and stroke during follow-up. RESULTS: No statistically significant changes in probabilities of death and hospitalizations for AMI and stroke within a 5-year follow-up period were identified in exudative AMD beneficiaries newly diagnosed in 2006, the beginning of widespread anti-VEGF use, compared with 2000. As an alternative to our main analysis, which excluded beneficiaries from nonexudative AMD group who received anti-VEGF therapies during follow-up, we performed a sensitivity analysis with this group of individuals reincluded (11% of beneficiaries newly diagnosed with nonexudative AMD in 2006). Results were similar. CONCLUSIONS: Introduction of anti-VEGF agents in 2006 for treating exudative AMD has not posed a threat of increased risk of AMI, stroke, or all-cause mortality.

Parental Criminal Justice Involvement and Children's Involvement With Child Protective Services: Do Adult Drug Treatment Courts Prevent Child Maltreatment?

BACKGROUND: In light of evidence showing reduced criminal recidivism and cost savings, adult drug treatment courts have grown in popularity. However, the potential spillover benefits to family members are understudied. OBJECTIVES: To examine: (1) the overlap between parents who were convicted of a substance-related offense and their children's involvement with child protective services (CPS); and (2) whether parental participation in an adult drug treatment court program reduces children's risk for CPS involvement. METHODS: Administrative data from North Carolina courts, birth records, and social services were linked at the child level. First, children of parents convicted of a substance-related offense were matched to (a) children of parents convicted of a nonsubstance-related offense and (b) those not convicted of any offense. Second, we compared children of parents who completed a DTC program with children of parents who were referred but did not enroll, who enrolled for <90 days but did not complete, and who enrolled for 90+ days but did not complete. Multivariate logistic regression was used to model group differences in the odds of being reported to CPS in the 1 to 3 years following parental criminal conviction or, alternatively, being referred to a DTC program. RESULTS: Children of parents convicted of a substance-related offense were at greater risk of CPS involvement than children whose parents were not convicted of any charge, but DTC participation did not mitigate this risk. Conclusion/Importance: The role of specialty courts as a strategy for reducing children's risk of maltreatment should be further explored.

Effect of diabetes mellitus on giant cell arteritis.

BACKGROUND: To determine if Type 2 diabetes mellitus (DM) is protective against giant cell arteritis (GCA) and to estimate the incidence of GCA diagnosis from Medicare claims. METHODS: Medicare 5% claims files from 1991 to 2011 were used to identify beneficiaries diagnosed with DM, but not GCA, within a 3-year ascertainment period. Propensity score matching was used to define a control group of nondiabetics with comparable demographic covariates. Competing risk regression was then used to assess the impact of DM diagnosis on GCA diagnosis. To allow for a 3-year ascertainment period, the analysis sample was limited to beneficiaries older than 68 years at baseline. RESULTS: A total of 151,041 beneficiaries diagnosed with DM were matched to an equal number of controls. Mean study follow-up was 67.75 months. GCA was diagnosed among 1116 beneficiaries with DM (0.73%) vs 465 (0.30%) controls. The risk of receiving a GCA diagnosis among patients with DM was increased by 100% (subhazard ratio, 2.00; 95% confidence interval, 1.78-2.25). The annual incidence of GCA diagnosis among claims for US Medicare beneficiaries older than 68 years old was 93 in 100,000. CONCLUSIONS: A DM diagnosis is not protective against a GCA diagnosis in the Medicare population. Our data suggest that a DM diagnosis increases the risk of GCA diagnosis within 5.7 years for Medicare beneficiaries older than 68 years.

Gaps in receipt of regular eye examinations among medicare beneficiaries diagnosed with diabetes or chronic eye diseases.

OBJECTIVE: To examine a wide range of factors associated with regular eye examination receipt among elderly individuals diagnosed with glaucoma, age-related macular degeneration, or diabetes mellitus (DM). DESIGN: Retrospective analysis of Medicare claims linked to survey data from the Health and Retirement Study (HRS). PARTICIPANTS: The sample consisted of 2151 Medicare beneficiaries who responded to the HRS. METHODS: Medicare beneficiaries with ≥ 1 of the 3 study diagnoses were identified by diagnosis codes and merged with survey information. The same individuals were followed for 5 years divided into four 15-month periods. Predictors of the number of periods with an eye examination evaluated were beneficiary demographic characteristics, income, health, cognitive and physical function, health behaviors, subjective beliefs about longevity, the length of the individual's financial planning horizon, supplemental health insurance coverage, eye disease diagnoses, and low vision/blindness at baseline. We performed logit analysis of the number of 15-month periods in which beneficiaries received an eye examination. MAIN OUTCOME MEASURES: The primary outcome measure was the number of 15-month periods with an eye examination. RESULTS: One third of beneficiaries with the study's chronic diseases saw an eye care provider in all 4 follow-up periods despite having Medicare. One quarter only obtained an eye examination at most during 1 of the four 15-month follow-up periods. Among the 3 groups of patients studied, utilization was particularly low for persons with diagnosed DM and no eye complications. Age, marriage, education, and a higher score on the Charlson index were associated with more periods with an eye examination. Male gender, being limited in instrumental activities of daily living at baseline, distance to the nearest ophthalmologist, and low cognitive function were associated with a reduction in frequency of eye examinations. CONCLUSIONS: Rates of eye examinations for elderly persons with DM or frequently occurring eye diseases, especially for DM, remain far below recommended levels in a nationally representative sample of persons with health insurance coverage. Several factors, including limited physical and cognitive function and greater distance to an ophthalmologist, but not health insurance coverage, account for variation in regular use.

The effects of total knee arthroplasty on physical functioning and health among the under age 65 population.

OBJECTIVES: This study examined the effects of total knee arthroplasty on six measures of physical functioning, self-rated health, pain, earnings, and employment status among US adults aged 51 to 63 years at baseline. METHODS: Data came from the Health and Retirement Study, a nationally representative longitudinal study conducted biannually. The analysis sample consisted of individuals aged 51 to 63 years at baseline with arthritis who were resurveyed at 2-year intervals from 1996 to 2010. Propensity score matching was used to compare outcomes of persons receiving total knee arthroplasty (TKA) with those of matched controls. Six measures of physical functioning were examined: lower-body mobility problems, instrumental activities of daily living limitations, activities of daily living limitations, and large muscle, fine motor, and gross motor limitations. Self-rated health and pain were also examined. The two employment-related outcomes were earnings and employment status. RESULTS: Receipt of TKA was associated with better outcomes for several measures of physical functioning, especially mobility limitations, pain, and self-rated health. Receipt of TKA was not associated with increased earnings or employment. CONCLUSIONS: Receipt of TKA yields important improvements in physical function among persons with an arthritis diagnosis who received the procedure before reaching the age of 65 years. This study contributes to knowledge about the benefits of TKA in a community setting among nonelderly recipients of TKA.

Addiction, drinking behavior, and driving under the influence.

Using a survey of drinkers (N = 1,634), we evaluated alternative explanations of heavy and binge drinking, driving under the influence (DUI), DUI arrests, speeding citations, and chargeable accidents. Explanations included socializing, short-term decision-making, unrealistic optimism, risk preferring behavior, and addiction. Most consistent relationships were between substance use and alcohol addiction and dependent variables for (1) binge drinking and (2) DUI episodes. Respondent characteristics (age, marital and employment status, race, etc.) had important roles for DUI arrests. Drinker-drivers and those arrested for DUI are partially overlapping groups with implications for treatment and policies detecting and incapacitating persons from drinking and driving.

Ten-year incidence of age-related macular degeneration according to diabetic retinopathy classification among medicare beneficiaries.

PURPOSE: To compare the longitudinal incidence over 10 years of dry and wet age-related macular degeneration (AMD) in a U.S. sample of Medicare beneficiaries with no diabetes mellitus, diabetes mellitus without retinopathy, nonproliferative diabetic retinopathy (NPDR), and proliferative diabetic retinopathy (PDR). METHODS: Using Medicare claims data, the 10-year incidence of dry and wet AMD from 1995 to 2005 in beneficiaries older than 69 years with newly diagnosed diabetes mellitus (n = 6,621), NPDR (n = 1,307), and PDR (n = 327) compared with each other and matched controls without diabetes for each group. RESULTS: After controlling for covariates, newly diagnosed NPDR was associated with significantly increased risk of incident diagnosis of dry AMD (hazard ratio, 1.24; 95% confidence interval: 1.08-1.43) and wet AMD (hazard ratio 1.68; 95% confidence interval: 1.23-2.31). Newly diagnosed PDR was associated with significantly increased risk of wet AMD only (hazard ratio 2.15; 95% confidence interval: 1.07-4.33). Diabetes without retinopathy did not affect risk of dry or wet AMD. There was no difference in risk of wet AMD in PDR compared with NPDR. CONCLUSION: Elderly individuals with NPDR or PDR may be at higher risk of AMD compared to those without diabetes mellitus or diabetic retinopathy.

Relative Productivity of For-Profit Hospitals: A Big or a Little Deal?

This study asks: Does the empirical evidence support the conclusion that for-profit (FP) hospitals are more productive or efficient than private not-for-profit (NFP) hospitals or non-federal public (PUB) hospitals? Alternative theories of NFP behavior are described. Our review of individual empirical hospital studies of quality, service mix, community benefit, and cost/efficiency in the United States published since 2000 indicates that no systematic difference exists in cost/efficiency, provision of uncompensated care, and quality of care. But FPs are more likely to provide profitable services, higher service intensity, have lower shares of uninsured and Medicaid patients, and are more responsive to external financial incentives. That FP hospitals are not more efficient runs counter to property rights theory, but their relative responsiveness to financial incentives supports it. There is little evidence that FP market presence changes NFP behaviors. Observed differences between FP and NFP hospitals are mostly a "little deal."

Longitudinal evidence on punctal plug use in an elderly population.

PURPOSE: The purpose of this study was to determine whether changes in Medicare reimbursement for punctal plug insertion were associated with a decrease in the incidence of insertion and dry eye diagnosis. METHODS: Incident cases of dry eye syndrome (DES) diagnoses and punctal plug insertions among Medicare beneficiaries were identified from Medicare 5% Part B from 1994 to 2008, using a 3-year look-back. Dry eye syndrome diagnoses and punctal plug insertion codes were ascertained from the international classification of diseases and current procedural terminology codes. Medicare payment data were obtained from the Centers for Medicare and Medicaid Services from 1994 to 2008 for punctal plug insertion. Rates were calculated for both the incidence of DES and the use of punctal plugs. RESULTS: From 2001 to 2008, inflation-adjusted Medicare reimbursement for punctal plug insertion decreased 55.1%, whereas the Medicare population-adjusted incidence of dry eye diagnosis increased 23.3%. Nine percent of individuals diagnosed with DES between 1991 and 2008 underwent punctal plug placement with a mean of 2.0 plugs placed per patient. Total punctal plug placement increased 322.2% between 1994 and 2003, and then reached a plateau. First-time punctal plug insertion rates within 365 days of DES diagnosis increased 111.8% from 1994 to 2002, and then declined 47.0% from 2002 to 2008. CONCLUSIONS: Although the frequency of DES diagnosis in the Medicare population has increased over time, first-time punctal plug insertion rates, especially within the first year following DES diagnosis, have declined coincidently with the increasing presence of a medical alternative and declining Medicare payment. Choice of therapies may have cost and care implications.

Incidence of nonarteritic anterior ischemic optic neuropathy: increased risk among diabetic patients.

OBJECTIVE: Previous studies have identified a higher prevalence of diabetes mellitus (DM) among patient cohorts with nonarteritic anterior ischemic optic neuropathy (NAION). We sought to determine the development of incident NAION among a group of newly diagnosed patients with DM and to estimate the incidence of NAION among the elderly. DESIGN: Medicare 5% database study. PARTICIPANTS: A total of 25 515 patients with DM and an equal number of age- and gender-matched nondiabetic patients. METHODS: Query of Medicare 5% claims files identified patients with a new diagnosis of DM in 1994. A randomly selected control group was created using 1-to-1 propensity score matching. Patients with a diagnosis of giant cell arteritis, preexisting DM, and age 68 years or older or >95 years were excluded. Patients with DM and controls were followed for the development of NAION over the following 4745 days. MAIN OUTCOME MEASURES: Incidence of NAION among patients with and without DM. RESULTS: In each group, 85% were white, 11% were black, and 4% were other race. Patients were aged 76.4 years, and 40% were male. Mean follow-up was 7.6 years. In the diabetes group, 188 individuals developed NAION (0.7%) compared with 131 individuals (0.5%; P < 0.01) in the control group. In unadjusted Cox regression analysis, having DM was associated with a 43% increased risk (hazard ratio [HR]: 1.431; 95% confidence interval [CI], 1.145-1.789) of developing NAION. After adjusting for other covariates, the risk of developing NAION among individuals with DM was reduced to 40% (HR 1.397; 95% CI, 1.115-1.750). Male gender increased an individual's risk of developing NAION by 32% (HR 1.319; 95% CI, 1.052-1.654). No other covariate was statistically significantly associated with developing NAION. The annual incidence of NAION was 82 per 100 000 persons. CONCLUSIONS: Diabetes mellitus significantly increased the risk of the diagnosis NAION. The incidence of NAION among patients aged more than 67 years may be higher than previously reported.

Severe adverse events after cataract surgery among medicare beneficiaries.

PURPOSE: To determine rates and risk factors associated with severe postoperative complications after cataract surgery and whether they have been changing over the past decade. DESIGN: Retrospective longitudinal cohort study. PARTICIPANTS: A total of 221 594 Medicare beneficiaries who underwent cataract surgery during 1994-2006. METHODS: Beneficiaries were stratified into 3 cohorts: those who underwent initial cataract surgery during 1994-1995, 1999-2000, or 2005-2006. One-year rates of postoperative severe adverse events (endophthalmitis, suprachoroidal hemorrhage, retinal detachment) were determined for each cohort. Cox regression analyses determined the hazard of developing severe adverse events for each cohort with adjustment for demographic factors, ocular and medical conditions, and surgeon case-mix. MAIN OUTCOME MEASURES: Time period rates of development of severe postoperative adverse events. RESULTS: Among the 221 594 individuals who underwent cataract surgery, 0.5% (1086) had at least 1 severe postoperative complication. After adjustment for confounders, individuals who underwent cataract surgery during 1994-1995 had a 21% increased hazard of being diagnosed with a severe postoperative complication (hazard ratio [HR] 1.21; 95% confidence interval [CI], 1.05-1.41) relative to individuals who underwent cataract surgery during 2005-2006. Those who underwent cataract surgery during 1999-2000 had a 20% increased hazard of experiencing a severe complication (HR 1.20; 95% CI, 1.04-1.39) relative to the 2005-2006 cohort. Risk factors associated with severe adverse events include a prior diagnosis of proliferative diabetic retinopathy (HR 1.62; 95% CI, 1.07-2.45) and cataract surgery combined with another intraocular surgical procedure on the same day (HR 2.51; 95% CI, 2.07-3.04). Individuals receiving surgery by surgeons with the case-mix least prone to developing a severe adverse event (HR 0.52; 95% CI, 0.44-0.62) had a 48% reduced hazard of a severe adverse event relative to recipients of cataract surgery performed by surgeons with the case-mix most prone to developing such outcomes. CONCLUSIONS: Rates of sight-threatening adverse events after cataract surgery declined during 1994-2006. Future efforts should be directed to identifying ways to reduce severe adverse events in high-risk groups.

Alcohol consumption in early adulthood and schooling completed and labor market outcomes at midlife by race and gender.

OBJECTIVES: We assessed the relation of alcohol consumption in young adulthood to problem alcohol consumption 10 years later and to educational attainment and labor market outcomes at midlife. We considered whether these relations differ between Blacks and Whites. METHODS: We classified individuals on the basis of their drinking frequency patterns with data from the 1982 to 1984 National Longitudinal Survey of Youth 1979 (respondents aged 19-27 years). We assessed alcohol consumption from the 1991 reinterview (respondents aged 26-34 years) and midlife outcomes from the 2006 reinterview (respondents aged 41-49 years). RESULTS: Black men who consumed 12 or more drinks per week at baseline had lower earnings at midlife, but no corresponding relation for Black women or Whites was found. Black men and Black women who consumed 12 or more drinks per week at baseline had lower occupational attainment than did White male non-drinkers and White female non-drinkers, respectively, but this result was not statistically significant. CONCLUSIONS: The relation between alcohol consumption in young adulthood and important outcomes at midlife differed between Blacks and Whites and between Black men and Black women, although Blacks' alcohol consumption at baseline was lower on average than was that of Whites.

The Opioid Epidemic Blunted the Mortality Benefit of Medicaid Expansion.

Although the Affordable Care Act's Medicaid expansion reduced uninsurance, less is known about its impact on mortality, especially in the context of the opioid epidemic. We conducted a difference-in-differences study comparing trends in mortality between expansion and nonexpansion states from 2011 to 2016 using the Centers for Disease Control and Prevention mortality data. We analyzed all-cause deaths, health care amenable deaths, drug overdose deaths, and deaths from causes other than drug overdose among adults aged 20 to 64 years. Medicaid expansion was associated with a 2.7% reduction (p = .020) in health care amenable mortality, and a 1.9% reduction (p = .042) in mortality not due to drug overdose. However, the expansion was not associated with any change in all-cause mortality (0.2% reduction, p = .84). In addition, drug overdose deaths rose more sharply in expansion versus nonexpansion states. The absence of all-cause mortality reduction until drug overdose deaths were excluded indicate that the opioid epidemic had a mitigating impact on any potential lives saved by Medicaid expansion.
