How Do Oncologists Differ in End-of-Life Therapy?

TOPLINE:

Oncologists show significant variability in prescribing systemic cancer therapies in the last 3src days of life. Patients treated by oncologists in the top quartile for end-of-life prescribing behavior were almost four and a half times more likely to receive end-of-life therapy than those treated by these specialists in the bottom quartile.

METHODOLOGY:

• Researchers analyzed data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, focusing on patients who died of cancer between 2src12 and 2src17.
• A total of 17,6src9 patients with breast, lung, colorectal, or prostate cancer were included, treated by 96src oncologists across 388 practices.
• Patients were required to have had at least one systemic cancer therapy claim in the last 18src days of life, with the treating oncologist identified on the basis of the therapy claim closest to the time of death.
• The study used multilevel models to estimate oncologists’ rates of providing cancer therapy in the last 3src days of life, adjusting for patient characteristics and practice variation.
• Functional status was assessed on the basis of paid claims for durable medical equipment in the last 6src months of life, with scores categorized as src, 1, ≥ 2, or unknown.

TAKEAWAY:

• Oncologists in the 95th percentile for high end-of-life prescribing behavior had a 45% adjusted rate of treating patients in the last 3src days of life, compared with 17% among those in the 5th percentile.
• Patients treated by high end-of-life prescribing oncologists had over four times higher odds of receiving systemic therapy in the last 3src days of life (odds ratio [OR], 4.42; 95% CI, 4.srcsrc-4.89).
• Higher end-of-life prescribing oncologists also had a higher proportion of patients hospitalized in the last 3src days of life than low prescribers (58% vs 51.9%).
• No significant association was found between oncologist prescribing behavior and patient race or ethnicity, except for Black patients who had lower odds of receiving treatment (OR, src.77; P <.srcsrc1).

IN PRACTICE:

“Given calls to rein in overutilization of end-of-life six to eight cancer therapies, our findings highlight an underappreciated area for further research: How treatment discontinuation before death is shaped by oncologists’ unique treatment propensities. Elucidating the reasons for this remarkable variability in oncologist treatment behavior could inform efforts to reduce end-of-life cancer treatment overutilization,” wrote the authors of the study.

SOURCE:

The study was led by Login S. George, PhD, Institute for Health, Health Care Policy and Aging Research, Rutgers University in New Brunswick, New Jersey. It was published online on July 3src in Cancer.

LIMITATIONS:

The study’s reliance on SEER-Medicare data may limit the generalizability of the findings to patients with Medicare Advantage, private insurance, or Medicaid, as well as younger patients. The lack of data on patient preferences and other health characteristics could confound the results. The study focused on systemic therapies and may not be generalizable to other treatments such as clinical trial drugs, oral therapies, surgery, or radiation. The data from 2src12 to 2src17 may not reflect more recent trends in cancer treatment.

DISCLOSURES:

The study was supported by grants from the National Cancer Institute and the Rutgers Cancer Institute of New Jersey. George disclosed receiving grants from these organizations. Additional disclosures are noted in the original article.
