Organization of cancer specialists in US physician practices and health systems.
This study’s objective was to describe the supply of cancer specialists, the organization of cancer care within versus outside of health systems, and the distance to multispecialty cancer centers. The authors used the 2018 Health Systems and Provider Database from the National Bureau of Economic Research and 2018 Medicare data to identify 46,341 unique physicians providing cancer care. They stratified physicians by discipline (adult/pediatric medical oncologists, radiation oncologists, surgical/gynecologic oncologists, other surgeons performing cancer surgeries, or palliative care physicians), system type (National Cancer Institute [NCI] Cancer Center system, non-NCI academic system, nonacademic system, or nonsystem/independent practice), practice size, and composition (single disciplinary oncology, multidisciplinary oncology, or multispecialty). They computed the density of cancer specialists by county and calculated distances to the nearest NCI Cancer Center. Results found that more than half of all cancer specialists (57.8%) practiced in health systems, but 55.0% of cancer-related visits occurred in independent practices. A majority of system-based physicians were in large practices with more than 100 physicians, while those in independent practices were in smaller practices. Breakdown by specialty type showed that practices in NCI Cancer Center systems (95.2%), non-NCI academic systems (95.0%), and nonacademic systems (94.3%) were primarily multispecialty, while fewer independent practices (44.8%) were. Many rural areas had sparse cancer specialty density, where the median travel distance to an NCI Cancer Center was 98.7 miles. Higher-income areas had shorter distances to NCI Cancer centers than low-income areas, even for individuals in suburban and rural areas.

Trends in rural-urban disparities among surgical specialties treating cancer, 2004-2017.
The purpose of this study was to assess trends over time in rural and urban disparities in the supply of surgeons treating patients with cancer. The researchers utilized the Area Health Resource File to conduct a retrospective observational study of medical workforce changes from 2004-2017. The study found that the density of surgical specialists in rural areas declined from 16 to 14 per 100,000 population and in urban areas from 33 to 31 per 100,000 population for a rural-urban disparity increase of 8%. The percentage increase in the supply disparity between the rural and urban workforce was largest for colorectal surgeons (66%) and general surgeons (72%). The study concluded that temporal changes in the rural-urban physician workforce depend on community factors, region, and area of specialization.

Urology workforce changes and implications for prostate cancer care among Medicare enrollees.
The purpose of this study was to characterize national trends in urologist workforce, practice organization, and management of incident prostate cancer. The investigators characterized shifts in urologist membership from smaller, independent groups to larger, multispecialty or hospital-owned practices. They indicated that this trend coincided with higher utilization of observation and surgical treatment for prostate cancer.

Increase in cancer center staff effort related to electronic patient portal use.
The authors examined patterns of use of electronic portals by clinic staff at a National Cancer Institute-designated comprehensive cancer center. They found that from 2011 to 2014, staff portal activity increased approximately 10-fold, and sixteen percent of all actions occurred outside clinic hours. They concluded that cancer center employee use of an electronic patient portal has increased markedly over time, particularly among nursing staff.
