Impact of changes in Medicaid coverage on physician provision of safety net care

Most Primary Care Physicians Provide Appointments, But Affordability Remains A Barrier For The Uninsured

The US uninsurance rate has nearly been cut in half under the Affordable Care Act, and access to care has improved for the newly insured, but less is known about how the remaining uninsured have fared. In 2012-13 and again in 2016 we conducted an experiment in which trained auditors called primary care offices, including federally qualified health centers, in ten states. The auditors portrayed uninsured patients seeking appointments and information on the cost of care and payment arrangements. In both time periods, about 80 percent of uninsured callers received appointments, provided they could pay the full cash amount. However, fewer than one in seven callers in both time periods received appointments for which they could make a payment arrangement to bring less than the full amount to the visit. Visit prices in both time periods averaged about $160. Trends were largely similar across states, despite their varying changes in the uninsurance rate. Federally qualified health centers provided the highest rates of primary care appointment availability and discounts for uninsured low-income patients.

The effect of North Carolina free clinics on hospitalizations for ambulatory care sensitive conditions among the uninsured

BACKGROUND

Free clinics are volunteer based organizations that provide health care services to low-income individuals for free or minimal cost. Communities served by a free clinic can provide ambulatory care services for uninsured individuals, reducing reliance on costly hospital admissions for ambulatory care sensitive conditions. This study examines whether free clinics in North Carolina reduce hospitalizations for ambulatory care sensitive conditions for uninsured adults.

METHODS

The study used North Carolina hospital discharge data from 2003 to 2007, restricted to uninsured adults residing in North Carolina (N = 270,325). Prevention Quality Indicators identified hospitalizations for ambulatory care sensitive conditions. The entry of new free clinics in some counties during this time period in conjunction with county-level and year fixed effects allows the logistic regression analysis to simulate a pre/post study design.

RESULTS

Discharges for ambulatory care sensitive conditions constituted 12.6% of the sample. Despite the limited coverage provided by free clinics, which serve 5.5% of the uninsured in North Carolina, uninsured adults in counties served by a free clinic had an 8.0% reduced odds of a hospitalization being for an ambulatory care sensitive condition. When the model is limited to ambulatory care sensitive conditions related to chronic conditions, the odds of a hospitalization of an uninsured adult for an ambulatory care sensitive condition in counties served by a free clinic is reduced by 9.0%.

CONCLUSION

Free clinics are effective providers of primary care services for uninsured individuals, particularly for those with chronic conditions. To enhance this impact by increasing free clinics' reach, state and local policy makers should support and encourage development of free clinics in high need areas.

Racial/Ethnic and Gender Disparities in Health Care Use and Access

OBJECTIVE

To document racial/ethnic and gender differences in health service use and access after the Affordable Care Act went into effect.

DATA SOURCE

Secondary data from the 2006-2014 National Health Interview Survey.

STUDY DESIGN

Linear probability models were used to estimate changes in health service use and access (i.e., unmet medical need) in two separate analyses using data from 2006 to 2014 and 2012 to 2014.

DATA EXTRACTION

Adult respondents aged 18 years and older (N = 257,560).

PRINCIPAL FINDINGS

Results from the 2006-2014 and 2012-2014 analyses show differential patterns in health service use and access by race/ethnicity and gender. Non-Hispanic whites had the greatest gains in health service use and access across both analyses. While there was significant progress among Hispanic respondents from 2012 to 2014, no significant changes were found pre-post-health care reform, suggesting access may have worsened before improving for this group. Asian men had the largest increase in office visits between 2006 and 2014, and although not statistically significant, the increase continued 2012-2014. Black women and men fared the worst with respect to changes in health care access.

CONCLUSIONS

Ongoing research is needed to track patterns of health service use and access, especially among vulnerable racial/ethnic and gender groups, to determine whether existing efforts under health care reform reduce long-standing disparities.

The availability of community health center services and access to medical care

BACKGROUND

Community Health Centers (CHCs) funded by Section 330 of the Public Health Service Act are an essential part of the health care safety net in the US. The Patient Protection and Affordable Care Act expanded the program significantly, but the extent to which the availability of CHCs improve access to care in general is not clear. In this paper, we examine the associations between the availability of CHC services in communities and two key measures of ambulatory care access - having a usual source of care and having any office-based medical visits over a one year period.

METHODS

We pooled six years of data from the Medical Expenditure Panel Survey (2008-2013) and linked it to geographic data on CHCs from Health Resources and Services Administration's Health Center Program Uniform Data System. We also link other community characteristics from the Area Health Resource File and the Dartmouth Institute's data files. The associations between CHC availability and our access measures are estimated with logistic regression models stratified by insurance status.

RESULTS

The availability of CHC services was positively associated with both measures of access among those with no insurance coverage. Additionally, it was positively associated with having a usual source of care among those with Medicaid and private insurance. These findings persist after controlling for key individual- and community-level characteristics.

CONCLUSIONS

Our findings suggest that an enhanced CHC program could be an important resource for supporting the efficacy of expanded Medicaid coverage under the Affordable Care Act and, ultimately, improving access to quality primary care for underserved Americans.

Organizational Factors Affect Safety-Net Hospitals' Breast Cancer Treatment Rates

OBJECTIVE

To identify key organizational approaches associated with underuse of breast cancer care.

SETTING

Nine New York City area safety-net hospitals.

STUDY DESIGN

Mixed qualitative-quantitative, cross-sectional cohort.

METHODS

We used qualitative comparative analysis (QCA) of key stakeholder interviews, defined organizational "conditions," calibrated conditions, and identified solution pathways. We defined underuse as no radiation after lumpectomy in women <75 years or mastectomy in women with ≥4 positive nodes, or no systemic therapy in women with tumors ≥1 cm. We used hierarchical models to assess organizational and patient factors' impact on underuse.

PRINCIPAL FINDINGS

Underuse varied by hospital (8-29 percent). QCA found lower underuse sites designated individuals to track and follow-up no-shows; shared clinical information during handoffs; had fully integrated electronic medical records enabling transfer of responsibility across specialties; had strong system support; allocated resources to cancer clinics; had a patient-centered culture paying close organizational attention to clinic patients. High underuse sites lacked these characteristics. Multivariate modeling found that hospitals with strong approaches to follow-up had low underuse rates (RR = 0.28; 0.08-0.95); individual patient characteristics were not significant.

CONCLUSIONS

At safety-net hospitals, underuse of needed cancer therapies is associated with organizational approaches to track and follow-up treatment. Findings provide varying approaches to safety nets to improve cancer care delivery.
