Association of Primary and Specialty Care Integration on Physician Communication and Cancer Screening in Safety-Net Clinics

Longer travel times to acute hospitals are associated with lower likelihood of cancer screening receipt among rural-dwelling adults in the U.S. South

PURPOSE

Given rural hospitals' role in providing outpatient services, we examined the association between travel burdens and receipt of cancer screening among rural-dwelling adults in the U.S. South region.

METHODS

First, we estimated network travel times and distances to access the nearest and second nearest acute care hospital from each rural census tract in the U.S. South. After appending the Centers for Disease Control's PLACES dataset, we fitted generalized linear mixed models.

RESULTS

Longer distances to the second nearest hospital are negatively associated with breast, colorectal, and cervical cancer screening receipt among eligible rural-dwelling adults. Rural-dwelling women in counties with 1 closure had reduced likelihood of breast cancer screening. Residence in a partial- or whole-county Health Professional Shortage Area (HPSA) was negatively associated with cancer screening receipt. Specialist (OB/GYN and gastroenterologist) supply was positively associated with receipt of cancer screening. Uninsurance was positively associated with cervical and breast cancer screening receipt. Medicaid expansion was associated with increased breast and cervical cancer screening.

CONCLUSIONS

Rural residents in partial-county primary care HPSAs had the lowest rates of breast, cervical, and colorectal cancer screening, compared with whole-county HPSAs and non-shortage areas. These residents also faced the greatest distances to their nearest and second nearest hospital. This is notable because rural residents in the South face greater travel burdens for cancer care compared with residents in other regions. Finally, the positive association between uninsurance and breast and cervical cancer screening may reflect the CDC's National Breast and Cervical Cancer Early Detection Program's effectiveness.

Health System Expansion and Changes in Medicare Beneficiary Utilization of Safety Net Providers

BACKGROUND

Evidence is limited on insured patients' use of safety net providers as vertically integrated health systems spread throughout the United States.

OBJECTIVES

To examine whether market-level health system penetration is associated with: (1) switches in Medicare beneficiaries' usual source of primary care from federally qualified health centers (FQHCs) to health systems; and (2) FQHCs' overall Medicare patient and visit volume.

RESEARCH DESIGN

Beneficiary-level discrete-time survival analysis and market-level linear regression analysis using Medicare fee-for-service claims data from 2013 to 2018.

SUBJECTS

A total of 659,652 Medicare fee-for-service beneficiaries aged 65 and older lived in one of 27,386 empirically derived primary care markets whose usual source of care in 2013 was an FQHC or a non-FQHC-independent physician organization that predominantly served low-income patients.

MEASURES

Beneficiary-year measure of the probability of switching to health system-affiliated physician organizations and market-year measures of the number of FQHC visits by Medicare beneficiaries, number of beneficiaries attributed to FQHCs, and FQHC Medicare market shares.

RESULTS

During 2013-2018, 16.5% of beneficiaries who sought care from FQHCs switched to health systems. When health system penetration increases from the 25th to 75th percentile, the probability of Medicare FQHC patient switching increases by 4.6 percentage points, with 22 fewer Medicare FQHC visits and 4 fewer beneficiaries attributed to FQHCs per market year. Complex patients and patients who sought care from non-FQHC, independent physician organizations exhibited higher rates of switching to health systems.

CONCLUSIONS

Health system expansion was associated with the loss of Medicare patients by FQHCs, suggesting potential negative spillovers of vertical integration on independent safety net providers.

Barriers and facilitators of colorectal cancer screening using the 5As framework: A systematic review of US studies

Despite clear evidence that regular screening reduces colorectal cancer (CRC) mortality and the availability of multiple effective screening options, CRC screening continues to be underutilized in the US. A systematic literature search of four databases - Ovid, Medline, EBSCHOhost, and Web of Science - was conducted to identify US studies published after 2017 that reported on barriers and facilitators to CRC screening adherence. Articles were extracted to categorize relevant CRC screening barriers or facilitators that were assessed against CRC screening outcomes using the 5As dimensions: Access, Affordability, Acceptance, Awareness, Activation. Sixty-one studies were included. Fifty determinants of screening within the 5As framework and two additional dimensions including Sociodemographics and Health Status were identified. The Sociodemographics, Access, and Affordability dimensions had the greatest number of studies included. The most common factor in the Access dimension was contact with healthcare systems, within the Affordability dimension was insurance, within the Awareness dimension was knowledge CRC screening, within the Acceptance dimension was health beliefs, within the Activation dimension was prompts and reminders, within the Sociodemographics dimension was race/ethnicity, and among the Health Status dimension was chronic disease history. Among all studies, contact with healthcare systems, insurance, race/ethnicity, age, and education were the most common factors identified. CRC screening barriers and facilitators were identified across individual, clinical, and sociocontextual levels. Interventions that consider multilevel strategies will most effectively increase CRC screening adherence.

A first look at breast cancer screening in over 1000 community health centers in the United States

Community Health Centers (CHCs) primarily serve low-income and vulnerable patients. Breast cancer screening recently became a quality-of-care metric in the annual Uniform Data System (UDS) report, and this study examines the first year of breast cancer screening data among 1375 CHCs in the United States. Clinics with available screening data (n = 1070) were categorized based on US region, state expansion of Medicaid to low-income adults under the Affordable Care Act, ranked terciles of race/ethnic composition (non-Hispanic Black, non-Hispanic Asian, and Hispanic/Latino patients), and proportion uninsured. Less than half of women eligible for breast cancer screening, 43.6% (95% CI:42.6%, 44.6%), were up-to-date. CHCs with medium or high proportions of Black (PR: 0.91, 0.86) and uninsured (PR: 0.90, 0.86) patients had between 9%-14% lower breast cancer screening rates than CHCs with low proportions of these populations. CHCs in Medicaid expansion states and in Northeastern states had significantly higher screening rates than non-expansion states and the Midwest, South, and Western states. In conclusion, our findings show that only half of women eligible who received care within CHCs were screened for breast cancer. Disparities in breast cancer screening rates are seen for clinics with high proportions of Black and uninsured patients, along with clinics outside the northeast and clinics in non-Medicaid expansion states. Targeted solutions centered around reducing cost, improving quality, and reducing structural disparities are needed to address low rates of breast cancer screening in low-income women who visited CHCs and already experience healthcare inequities.

Perceptions on Barriers and Facilitators to Colonoscopy Completion After Abnormal Fecal Immunochemical Test Results in a Safety Net System

IMPORTANCE

The effectiveness of stool-based colorectal cancer (CRC) screening, including fecal immunochemical tests (FITs), relies on colonoscopy completion among patients with abnormal results, but in safety net systems and federally qualified health centers, in which FIT is frequently used, colonoscopy completion within 1 year of an abnormal result rarely exceeds 50%. Clinician-identified factors in follow-up of abnormal FIT results are understudied and could lead to more effective interventions to address this issue.

OBJECTIVE

To describe clinician-identified barriers and facilitators to colonoscopy completion among patients with abnormal FIT results in a safety net health care system.

DESIGN, SETTING, AND PARTICIPANTS

This qualitative study was conducted using semistructured key informant interviews with primary care physicians (PCPs) and staff members in a large safety net health care system in Washington state. Eligible clinicians were recruited through all-staff meetings and clinic medical directors. Interviews were conducted from February to December 2020 through face-to-face interactions or digital meeting platforms. Interview transcripts were analyzed deductively and inductively using a content analysis approach. Data were analyzed from September through December 2020.

MAIN OUTCOMES AND MEASURES

Barriers and facilitators to colonoscopy completion after an abnormal FIT result were identified by PCPs and staff members.

RESULTS

Among 21 participants, there were 10 PCPs and 11 staff members; 20 participants provided demographic information. The median (interquartile range) age was 38.5 (33.0-51.5) years, 17 (85.0%) were women, and 9 participants (45.0%) spent more than 75% of their working time engaging in patient care. All participants identified social determinants of health, organizational factors, and patient cognitive factors as barriers to colonoscopy completion. Participants suggested that existing resources that addressed these factors facilitated colonoscopy completion but were insufficient to meet national follow-up colonoscopy goals.

CONCLUSIONS AND RELEVANCE

In this qualitative study, responses of interviewed PCPs and staff members suggested that the barriers to colonoscopy completion in a safety net health system may be modifiable. These findings suggest that interventions to improve follow-up of abnormal FIT results should be informed by clinician-identified factors to address multilevel challenges to colonoscopy completion.
