County-Level Study of Lung Cancer Surgery Reveals Disparities

Documenting differences in surgical treatment at the county level contributes invaluable evidence to stimulate corrective health policy changes at all levels.

The Research

Recently, he expanded his research to the county level, which is the common starting point for measuring access to health care in the US and for recognizing the need for more targeted interventions.

Jemal and other researchers, including 4 others from the ACS Surveillance & Health Equity Science program, did a large 7-year study of people diagnosed with early-stage non-small cell lung cancer (NSCLC, the most common type of lung cancer) in about 2,300 counties from 39 states, plus the District of Columbia, and the city of Detroit.

They found that every state—even those with high overall rates of surgeries intended to cure NSCLC—had counties where only a small percentage of NSCLC patients received surgery. The differences between counties was substantially greater than the differences they found between states. The variation was significantly associated with several factors that are potentially modifiable. Those factors included the percentage of people without health insurance and below the federal poverty level, rural/urban status, and surgeon-to-population ratio.

Why It Matters

Documenting differences in surgical treatment at the county level “contributes invaluable evidence to stimulate corrective [health] policy changes” at the federal, state, and county level, the authors said. For instance, expanding Medicaid eligibility and public health programs that target rural communities “may enhance financial well-being, health insurance coverage, and access to health care at the county level,” the authors wrote. County-level studies, they said, can stimulate initiatives that target the improvement of referral or care coordination between nearby counties, regardless of state boundaries.
