Housing-Sensitive Health Conditions Can Predict Poor-Quality Housing

Improving housing quality may improve residents' health, but identifying buildings in poor repair is challenging. We developed a method to improve health-related building inspection targeting. Linking New York City Medicaid claims data to Landlord Watchlist data, we used machine learning to identify housing-sensitive health conditions correlated with a building's presence on the Watchlist. We identified twenty-three specific housing-sensitive health conditions in five broad categories consistent with the existing literature on housing and health. We used these results to generate a housing health index from building-level claims data that can be used to rank buildings by the likelihood that their poor quality is affecting residents' health. We found that buildings in the highest decile of the housing health index (controlling for building size, community district, and subsidization status) scored worse across a variety of housing quality indicators, validating our approach. We discuss how the housing health index could be used by local governments to target building inspections with a focus on improving health.

Association Between Medicaid Expansion and the Use of Outpatient General Surgical Care Among US Adults in Multiple States

Importance

The Affordable Care Act expanded access to Medicaid coverage in 2014 for individuals living in participating states. Whether expanded coverage was associated with increases in the use of outpatient surgical care, particularly among underserved populations, remains unknown.

Objective

To evaluate the association between state participation in the Affordable Care Act Medicaid expansion reform and the use of outpatient surgical care.

Design, Setting, and Participants

This case-control study used a quasi-experimental difference-in-differences design to compare the use of outpatient surgical care at the facility and state levels by patient demographic characteristics and payer categories (Medicaid, private insurance, and no insurance). Data from 2013 (before Medicaid expansion reform) and 2015 (after Medicaid expansion reform) were obtained from the State Ambulatory Surgery and Services Database of the Healthcare Cost and Utilization Project. The absolute and mean numbers of procedures performed at outpatient surgical centers in 2 states (Michigan and New York) that participated in Medicaid expansion (expansion states) were compared with those performed at outpatient surgical centers in 2 states (Florida and North Carolina) that did not participate in Medicaid expansion (nonexpansion states). The population-based sample included 207 176 patients aged 18 to 64 years who received 4 common outpatient procedures (laparoscopic cholecystectomy, breast lumpectomy, open inguinal hernia repair, and laparoscopic inguinal hernia repair). Data were analyzed from May 19 to August 25, 2019.

Interventions

State variation in the adoption of Medicaid expansion before and after expansion reform was implemented through the Affordable Care Act.

Main Outcomes and Measures

Changes in the mean number of procedures performed at the facility level before and after Medicaid expansion reform in states with and without expanded Medicaid coverage.

Results

A total of 207 176 patients (106 395 women [51.35%] and 100 781 men [48.65%]; mean [SD] age, 45.7 [12.4] years) were included in the sample. Overall, 116 752 procedures were performed in Medicaid expansion states and 90 424 procedures in nonexpansion states. A 9.8% increase (95% CI, 0.4%-20.0%; P = .04) in cholecystectomies, a 26.1% increase (95% CI, 9.8%-44.7%; P = .001) in lumpectomies, and a 16.3% increase (95% CI, 2.9%-31.5%; P = .02) in laparoscopic inguinal hernia repairs were observed at the facility level in expansion states compared with nonexpansion states. Among patients with Medicaid coverage, the mean number of procedures performed in all 4 procedure categories increased between 60.5% (95% CI, 24.7%-106.6%; P < .001) and 79.2% (95% CI, 53.5%-109.2%; P < .001) at the facility level. The increases in the number of Medicaid patients who received treatment exceeded the reductions in the number of uninsured patients who received treatment with laparoscopic cholecystectomy, open inguinal hernia repair, and laparoscopic inguinal hernia repairs in expansion states compared with nonexpansion states. Black patients received more laparoscopic cholecystectomies, lumpectomies, and open inguinal hernia repairs in expansion states than in nonexpansion states.

Conclusions and Relevance

Study results suggest that Medicaid expansion was associated with increases in the use of outpatient surgical care in states that participated in Medicaid expansion. Most of this increase represented patients who were newly treated rather than patients who converted from no insurance to Medicaid coverage.

How Medicaid Expansion Affected Out-of-Pocket Health Care Spending for Low-Income Families

ISSUE. Prior research shows that low-income residents of states that expanded Medicaid under the Affordable Care Act are less likely to experience financial barriers to health care access, but the impact on out-of-pocket spending has not yet been measured. GOAL. Assess how the Medicaid expansion affected out-of-pocket health care spending for low-income families compared to those in states that did not expand and consider whether effects differed in states that expanded under conventional Medicaid rules vs. waiver programs. METHODS. Analysis of the Consumer Expenditure Survey 2010–2015. KEY FINDINGS AND CONCLUSIONS. Compared to families in nonexpansion states, low-income families in states that did expand Medicaid saved an average of $382 in annual spending on health care. In these states, low-income families were less like to report any out-of-pocket spending on insurance premiums or medical care than were similar families in nonexpansion states. For families that did have some out-of-pocket spending, spending levels were lower in states that expanded Medicaid. Low-income families in Medicaid expansion states were also much less likely to have catastrophically high spending levels. The form of coverage expansion — conventional Medicaid or waiver rules — did not have a statistically significant effect on these outcomes.
