Association of Receipt of a Housing Voucher With Subsequent Hospital Utilization and Spending.

ABSTRACT:

Importance

Although neighborhoods are thought to be an important health determinant, evidence for the relationship between neighborhood poverty and health care use is limited, as prior studies have largely used observational data without an experimental design.

Objective

To examine whether housing policies that reduce exposure to high-poverty neighborhoods were associated with differences in long-term hospital use among adults and children.

Design, setting, and participants

Exploratory analysis of the Moving to Opportunity for Fair Housing Demonstration Program, a randomized social experiment conducted in 5 US cities. From 1994 to 1998, 4604 families in public housing were randomized to 1 of 3 groups: a control condition, a traditional Section 8 voucher toward rental costs in the private market, or a voucher that could only be used in low-poverty neighborhoods. Participants were linked to all-payer hospital discharge data (1995 through 2014 or 2015) and Medicaid data (1999 through 2009). The final follow-up date ranged from 11 to 21 years after randomization.

Exposures

Receipt of a traditional or low-poverty voucher vs control group.

Main outcomes and measures

Rates of hospitalizations and hospital days, and hospital spending.

Results

Among 4602 eligible individuals randomized as adults, 4072 (88.5%) were linked to health data (mean age, 33 years [SD, 9.0 years]; 98% female; median follow-up, 11 years). There were no significant differences in primary outcomes among adults randomized to receive a voucher compared with the control group (unadjusted hospitalization rate, 14.0 vs 14.7 per 100 person-years, adjusted incidence rate ratio [IRR], 0.95 [95% CI, 0.84-1.08; P?=?.45]; hospital days, 62.8 vs 67.0 per 100 person-years; IRR, 0.93 [95% CI, 0.77-1.13; P?=?.46]; yearly spending, $2075 vs $1977; adjusted difference, -$129 [95% CI, -$497 to $239; P?=?.49]). Among 11?290 eligible individuals randomized as children, 9118 (80.8%) were linked to health data (mean age, 8 years [SD, 4.6 years]; 49% female; median follow-up, 11 years). Receipt of a housing voucher during childhood was significantly associated with lower hospitalization rates (6.3 vs 7.3 per 100 person-years; IRR, 0.85 [95% CI, 0.73-0.99; P?=?.03]) and yearly inpatient spending ($633 vs $785; adjusted difference, -$143 [95% CI, -$256 to -$31; P?=?.01]) and no significant difference in hospital days (25.7 vs 28.8 per 100 person-years; IRR, 0.92 [95% CI, 0.77-1.11; P?=?.41]).

Conclusions and relevance

In this exploratory analysis of a randomized housing voucher intervention, adults who received a housing voucher did not experience significant differences in hospital use or spending. Receipt of a voucher during childhood was significantly associated with lower rates of hospitalization and less inpatient spending during long-term follow-up.

Project description:AimsMethamphetamine Use Disorder is prevalent in South Africa. This analysis uses data from a contingency management (CM) pilot study in South Africa to replicate and expand on a U.S.-based study showing that CM voucher spending was associated with drug abstinence behavior.DesignParticipants with methamphetamine-use disorder were enrolled in an 8-week CM trial requiring thrice weekly visits and received cash vouchers in exchange for stimulant-negative urines at each visit.ParticipantsParticipants were 33 treatment-seeking individuals with methamphetamine use disorder including 22 men (66.7%) and 11 women (33.3%) with a mean age of 34 years (S.D. = 7.7). Participants reported using methamphetamine for a mean of 11.7 years (S.D. = 4.9).SettingAll study procedures took place in South Africa between August 2016 and May 2018.MeasurementsA time-lagged counting process Cox Proportional Hazards model for recurrent event survival analysis examined the relationship between frequency of and participant-categorized type of CM expenditures (hedonic, utilitarian, consumable or durable) and drug abstinence.FindingsAfter controlling for severity of baseline methamphetamine use and accumulated CM earnings (proxied by cumulative negative urines), those spending CM earnings at a previous visit ("spenders") were more likely to produce stimulant-negative urine samples subsequently, compared to those who did not ("savers") [OR = 1.23, CI = 1.08-1.53, p = .002]. There were significantly more cumulative stimulant-negative results among spenders vs. savers, p < .001, although cumulative spending did not significantly predict abstinence once spending in the prior time period was controlled for, suggesting a recency effect tied to the underlying spending mechanism. When extending the original analyses to look at the effect of spending on current abstinence, controlling only for recent abstinence (rather than cumulative abstinence), spending was no longer a significant predictor. Spending type did not affect methamphetamine abstinence. Qualitative results suggest spending CM vouchers may support social reintegration over the course of the trial.ConclusionsAbstinence outcomes are a function of CM spending in both the U.S. and South Africa. Findings of a significant relationship between contingency management spending and subsequent stimulant-negative urine samples across geographic locations provide guidance toward future work in optimizing CM efficacy.

Project description:ImportanceDelivering low-value care can lead to unnecessary follow-up services and associated costs, and such care cascades have not been well examined in common clinical scenarios.ObjectiveTo evaluate the utilization and costs of care cascades of prostate-specific antigen (PSA) tests for prostate cancer screening, as the routine use of which among asymptomatic men aged 70 years and older is discouraged by multiple guidelines.Design, setting, and participantsThis cross-sectional study included men aged 70 years and older without preexisting prostate conditions enrolled in a Medicare Advantage plan during January 2016 to December 2018 with at least 1 outpatient visit. Medical billing claims data from the deidentified OptumLabs Data Warehouse were used. Data analysis was conducted from September 2020 to August 2021.ExposuresAt least 1 claim for low-value PSA tests for prostate cancer screening during the observation period.Main outcomes and measuresUtilization of and spending on low-value PSA cancer screening and associated care cascades and the difference in overall health care utilization and spending among individuals receiving low-value PSA cancer screening vs those who did not, adjusting for observed characteristics using inverse probability of treatment weighting.ResultsOf 995 442 men (mean [SD] age, 78.0 [5.6] years) aged 70 years or older in a Medicare Advantage plan included in this study, 384 058 (38.6%) received a low-value PSA cancer screening. Utilization increased for each subsequent cohort from 2016 to 2018 (49 802 of 168 951 [29.4%] to 134 404 of 349 228 [38.5%] to 199 852 of 477 203 [41.9%]). Among those receiving initial low-value PSA cancer screening, 241 188 of 384 058 (62.8%) received at least 1 follow-up service. Repeated PSA testing was the most common, and 27 268 (7.1%) incurred high-cost follow-up services, such as imaging, radiation therapy, and prostatectomy. Utilization and spending associated with care cascades also increased from 2016 to 2018. For every $1 spent on a low-value PSA cancer screening, an additional $6 was spent on care cascades. Despite avoidable care cascades, individuals who received low-value PSA cancer screening were not associated with increased overall health care utilization and spending during the 1-year follow-up period compared with an unscreened population.Conclusions and relevanceIn this cross-sectional study, low-value PSA tests for prostate cancer screening remained prevalent among Medicare Advantage plan enrollees and were associated with unnecessary expenditures due to avoidable care cascades. Innovative efforts from clinicians and policy makers, such as payment reforms, to reduce initial low-value care and avoidable care cascades are warranted to decrease harm, enhance equity, and improve health care efficiency.

Project description:Importance:Medicaid expansion was widely expected to alleviate the financial stresses faced by hospitals by providing additional revenue in the form of Medicaid reimbursements from patients previously receiving uncompensated care. Among nonprofit hospitals, which receive tax-exempt status in part because of their provision of uncompensated care, Medicaid expansion could have released hospital funds toward other community benefit activities. Objective:To examine changes in nonprofit hospital spending on community benefit activities after Medicaid expansion. Design, Setting, and Participants:This cohort study used difference-in-differences analysis of 1666 US nonprofit hospitals that filed Internal Revenue Service Form 990 Schedule H detailing their community benefit expenditures between 2011 and 2017. The analysis was conducted from February to September 2019. Exposures:State Medicaid expansion between 2011 and 2017. Main Outcomes and Measures:Percentage of hospital operating expenditures attributable to charity care and subsidized care, bad debt (ie, unreimbursed spending for care of patients who did not apply for charity care), unreimbursed Medicaid spending, noncare direct community spending, and total community benefit spending. Results:Of 1478 hospitals in the sample in 2011, nearly half (653 [44.2%]) were small hospitals with fewer than 100 beds, and nearly 70% of hospitals (1023 [69.2%]) were in urban areas. Among the 1666 nonprofit hospitals, Medicaid expansion was associated with a decrease in spending on charity care and subsidized care (-0.68 [95% CI, -0.99 to -0.37] percentage points from a baseline mean [SD] of 3.6% [4.0%] of total hospital expenditures; P?<?.001) and in bad debt (-0.17 [95% CI, -0.32 to -0.01] percentage points). There was an increase in unreimbursed spending attributable to caring for Medicaid patients (0.85 [95% CI, 0.60 to 1.10] percentage points; P?=?.04), which canceled out uncompensated care savings from the expansion. Noncare direct community expenditures decreased overall (-0.24 [95% CI, -0.48 to 0.00] percentage points; P?=?.049). Direct community expenditures remained more stable in small hospitals (-0.07 [95% CI, -0.20 to 0.05] percentage points; P?=.26) compared with large hospitals (-0.37 [95% CI, -0.86 to 0.12] percentage points; P?=?.14) and in nonurban hospitals (0.02 [95% CI, -0.09 to 0.14] percentage points; P?=?.70) compared with urban hospitals (-0.36 [95% CI, -0.73 to 0.01] percentage points; P?=?.06). Conclusions and Relevance:In this study, Medicaid expansion was associated with a decrease in nonprofit hospitals' burden of providing uncompensated care, but this financial relief was not redirected toward spending on other community benefits.

Project description:ObjectiveTo determine if greater non-profit hospital spending for community benefits is associated with better health outcomes in the county where they are located.Data sources and study settingCommunity benefit data from IRS Form 990/Schedule H was linked to health outcome data from Area Health Resource Files, Map the Meal Gap, and Medicare claims from the Center for Medicare and Medicaid Services at the county level. Counties with at least one non-profit hospital in the United States from 2015 to 2019 (N = 5469 across the 5 years) were included.Study designWe ran multiple regressions on community benefit expenditures linked with the number of health professionals, food insecurity, and adherence to diabetes and hypertension medication for each county.Data collectionThe three outcomes were chosen based on prior studies of community benefit and a recent survey sent to 12 health care executives across four regions of the U.S. Data on community benefit expenditures and health outcomes were aggregated at the county level.Principal findingsAverage hospital community benefit spending in 2019 was $63.6 million per county ($255 per capita). Multivariable regression results did not demonstrate significant associations of total community benefit spending with food insecurity or medication adherence for diabetes. Statistically significant associations with the number of health professionals per 1000 (coefficient, 12.10; SE, 0.32; p < 0.001) and medication adherence for hypertension (marginal effect, 0.27; SE, 0.09; p = 0.003) were identified, but both would require very large increases in community benefit spending to meaningfully improve outcomes.ConclusionsDespite varying levels of non-profit hospital community benefit investment across counties, higher community benefit expenditures are not associated with an improvement in the selected health outcomes at the county level. Hospitals can use this information to reassess community benefit strategies, while federal, state, and local governments can use these findings to redefine the measures of community benefit they use to monitor and grant tax exemption.
