Impact of gentrification on adult mental health

OBJECTIVE

To estimate the net effect of living in a gentrified neighborhood on probability of having serious psychological distress.

DATA SOURCES

We pooled 5 years of secondary data from the California Health Interview Survey (2011-2015) and focused on southern California residents.

STUDY DESIGN

We compared adults (n = 43 815) living in low-income and gentrified, low-income and not gentrified, middle- to high-income and upscaled, and middle- to high-income and not upscaled neighborhoods. We performed a probit regression to test whether living in a gentrified neighborhood increased residents' probabilities of having serious psychological distress in the past year and stratified analyses by neighborhood tenure, homeownership status, and low-income status. Instrumental variables estimation and propensity scores were applied to reduce bias arising from residential selection and simultaneity. An endogenous treatment effects model was also applied in sensitivity analyses.

DATA COLLECTION/EXTRACTION METHODS

Adults who completed the survey on their own and lived in urban neighborhoods with 500 or more residents were selected for analyses. Survey respondents who scored 13 and above on the Kessler 6 were categorized as having serious psychological distress in the past year. We used eight neighborhood change measures to classify respondents' neighborhoods.

PRINCIPAL FINDINGS

Living in a gentrified and upscaled neighborhood was associated with increased likelihood of serious psychological distress relative to living in a low-income and not gentrified neighborhood. The average treatment effect was 0.0141 (standard error = 0.007), which indicates that the prevalence of serious psychological distress would have been 1.4 percentage points less if none of the respondents lived in gentrified neighborhoods. Gentrification appears to have a negative impact on the mental health of renters, low-income residents, and long-term residents. This effect was not observed among homeowners, higher-income residents, and recent residents.

CONCLUSIONS

Gentrification levies mental health costs on financially vulnerable community members and can worsen mental health inequities.

Do Medicare Beneficiaries Living With HIV/AIDS Choose Prescription Drug Plans That Minimize Their Total Spending?

This article examines whether California Medicare beneficiaries with HIV/AIDS choose Part D prescription drug plans that minimize their expenses. Among beneficiaries without low-income supplementation, we estimate the excess cost, and the insurance policy and beneficiary characteristics responsible, when the lowest cost plan is not chosen. We use a cost calculator developed for this study, and 2010 drug use data on 1453 California Medicare beneficiaries with HIV who were taking antiretroviral medications. Excess spending is defined as the difference between projected total spending (premium and cost sharing) for the beneficiary’s current drug regimen in own plan vs spending for the lowest cost alternative plan. Regression analyses related this excess spending to individual and plan characteristics. We find that beneficiaries pay more for Medicare Part D plans with gap coverage and no deductible. Higher premiums for more extensive coverage exceeded savings in deductible and copayment/coinsurance costs. We conclude that many beneficiaries pay for plan features whose costs exceed their benefits.

How much 'skin in the game' do medicare beneficiaries have? The increasing financial burden of health care spending, 1997-2003

Rising health costs and an aging population present critical policy challenges. This paper examines the financial burden of out-of-pocket health spending among Medicare beneficiaries between 1997 and 2003. Over this period, median out-of-pocket spending as a share of income increased from 11.9 percent to 15.5 percent. In 2003, the 25 percent of beneficiaries with the largest burden spent at least 29.9 percent of their income on health care, while 39.9 percent spent more than a fifth of their income on health care. Results suggest that sustained increases in out-of-pocket spending could make health care less affordable for all but the highest-income beneficiaries.

Volume responses to Medicare payment reductions with multiple payers: a test of the McGuire-Pauly model

The effects of changing financial incentives on physician's practice behaviour have long been of interest to researchers and policy makers. We test a model of physician volume response within the context of multiple payers developed by Thomas McGuire and Mark Pauly. A panel data set covering discharges from about 200 hospitals in the US over 45 months is used to carry out the empirical investigation. A fixed-effect model with generalized least squares and instrumental variable specifications is used to compute empirical evidence of volume responses from eight specialties experiencing varying degrees of Medicare payment reductions following the implementation of Omnibus Budget Reconciliation Acts of 1989 and 1990. The empirical findings are compared with McGuire and Pauly's simulated predictions. We note that in examining physician responses to Medicare payment reductions in the context of a multi-payer environment, it becomes evident that only fixing one payer's reimbursement policy is at best a partial solution to cost containment. We echo observations made by other analysts that physician responses to payment changes can be quite complex. Physicians do not all respond to payment reduction in the same way.

Physician payment reform in the United States

The United States recently adopted an entirely new system of paying physicians for the services they provide to elderly and disabled patients. The new system is based on a fee schedule in which the relative values among different services are derived on the basis of the cost of providing such services. To control expenditure growth, a system of Volume Performance Standards (VPSs) was adopted, which explicitly links physician fee levels to the success the physician community has in controlling the total volume of services provided. This article presents and analyzes the new payment system and examines its applicability to other countries. It concludes that the methodology used to develop the fee schedule may be useful to other countries, particularly if they are unable to reach a consensus on appropriate physician fee levels, but that the VPS system needs to be refined in a number of ways before it can be successfully exported.

Models of adult day care: findings from a national survey

We examined a nationally representative sample of 60 adult day care centers to describe the state of this evolving care modality after a decade's growth. Results indicate that day care centers can be categorized into three models of care, each of which serves a distinctive subpopulation. Model appropriateness was tested with analysis of variance of differences in participant characteristics. Services, staffing, costs, and other program features are contrasted among the three models.

The impact of changing medicare reimbursement rates on physician-induced demand

This paper examines how changes in Medicare reimbursement rates affect the degree to which physicians induce demand for Medicare services. Demand inducement is measured by analyzing changes in the intensity and quantity of services provided and the number of ancillary services ordered. The empirical work is based on data that include copies of all Medicare claims for Colorado physicians between 1976 and 1978. During that period a change in the state's Medicare reimbursement system occurred, resulting in a large increase in some physicians' reimbursement rates and a relative decrease in those of others. Using this "natural experiment," we can determine how changes in financial incentives affect various forms of demand inducement. The study results are consistent with the theory that demand inducement exists. It appears to take several forms: provision of more highly intensive medical and surgical services, greater quantities of surgical services, and ordering of more laboratory tests.
