Increased area-level medical spending is not correlated with improved patient outcomes or quality, thereby supporting the case for spending reductions in high-spending regions. However, all additional spending need not be wasteful. Examining the care of patients with colorectal cancer, we show that high-spending regions are more likely than other regions to use recommended care but are also more likely to use discretionary and nonrecommended care, the latter of which has adverse outcomes for patients. Our results show that instead of cutting spending, policies designed to target services to patients most likely to benefit could increase the value of medical spending.

Goals of Work: The National Cancer Institute's Cancer Care Outcomes Research and Surveillance (CanCORS) Consortium is conducting a population-based study of newly diagnosed patients with lung and colorectal cancer to describe the experience of persons living with cancer and to understand which barriers present the most significant obstacles to their receipt of appropriate care. The keystone to this effort is the baseline patient survey administered approximately 4 months after diagnosis., Patients and Methods: We developed a survey to obtain information from patients newly diagnosed with lung and colorectal cancer about their personal characteristics, decision making, experience of care, and outcomes. We conducted a pilot study to evaluate the feasibility of a lengthy and clinically detailed interview in a convenience sample of patients within 8 months of diagnosis (n=71)., Main Results: The median length of the interviews was 75 min for patients with lung cancer (range 43-130) and 82 min for patients with colorectal cancer (range 46-119). Most patients had received some form of treatment for their cancer: 66.1% had undergone surgery, 28.2% had received radiation therapy, and 54.9% were treated with chemotherapy. In addition, 26.7% reported their overall health was less than 70 on a 0-100 scale, demonstrating that patients with substantial health impairment were able to complete the survey., Conclusions: A clinically detailed survey of newly diagnosed lung and colorectal cancer patients is feasible. A modified version of this survey is being fielded by the CanCORS Consortium and should provide much needed population-based data regarding patients' experiences across the continuum of cancer care and their outcomes.

Purpose: To identify opportunities for improving care, we evaluated patients' perceptions of the quality of their cancer care by race, ethnicity, and language., Patients and Methods: We surveyed a population-based cohort of 1,067 patients with colorectal cancer in northern California approximately 9 months after diagnosis. Adjusting for clinical and demographic factors, mean problem scores were analyzed on a 100-point scale for six domains of care., Results: Mean problem scores were highest for health information (47.8), followed by treatment information (32.3), psychosocial care (31.7), coordination of care (21.3), confidence in providers (13.1), and access to cancer care (12.7). In adjusted comparisons with white patients, African American patients reported more problems with coordination of care (difference, 9.8; P < .001), psychosocial care (difference, 7.2; P = .03), access to care (difference, 6.6; P = .03), and health information (difference, 12.5; P < .001). Asian/Pacific Islander patients reported more problems than did white patients with coordination of care (difference, 13.2; P < .001), access to care (difference, 15.5; P < .001), and health information (difference, 12.6; P = .004). Hispanic patients tended to report more problems with coordination of care (difference, 4.4; P = .06), access to care (difference, 5.8; P = .08), and treatment information (difference, 7.0; P = .06). Non-English-speaking white patients reported more problems than other white patients with coordination of care (difference, 21.9; P < .001), psychosocial care (difference, 16.1; P = .009), access to care (difference, 19.8; P = .003), and treatment information (difference, 17.8; P = .002). Non-English-speaking Hispanic patients reported more problems than other Hispanic patients with confidence in providers (difference, 16.9; P = .01)., Conclusion: Efforts to improve patients' experiences with cancer care should address disparities by race, ethnicity, and language, particularly in coordination of care, access to care, and the provision of relevant information.

Background: Increases in the market share of managed care in an area are associated with decreases in expenditures in the fee-for-service sector (i.e., a spillover effect). Given concerns that these decreases in expenditures result from reductions in necessary care, we examined associations between increases in managed care market share and changes in the quality of care delivered to cancer patients in the fee-for-service sector., Methods: We studied a population-based sample of fee-for-service Medicare beneficiaries aged 66 years or older who were diagnosed with breast (N = 41,394) or colorectal (N = 48,027) cancer during 1993-1999. We used fixed effects regression analysis of SEER cancer registry and Medicare claims data to assess whether county-level increases in the market share of managed care over time were associated with the quality of cancer care. All statistical tests were two-sided., Results: Increases in the market share of managed care were not associated with most quality indicators, including receipt of surveillance mammography after diagnosis for patients with breast cancer (P = .83), receipt of radiation after breast-conserving surgery among women who underwent breast-conserving surgery (P = .16), receipt of adjuvant chemotherapy for patients with stage III colorectal cancer (P = .94), or surveillance colonoscopy after treatment for colorectal cancer (P = .39). Increases in the market share of managed care were associated with increased rates of surveillance carcinoembryonic antigen testing for colorectal cancer patients (P = .001)., Conclusions: Increases in managed care market share had limited or no effect on the quality of care for cancer patients. Concerns that increases in managed care would have large negative spillover effects on the quality of cancer care appear to be unfounded; however, the potential for managed care to stimulate improved quality throughout the medical care system have not yet been realized.

Purpose: Randomized trials have demonstrated that adjuvant chemotherapy improves survival for patients with stage III colon cancer and that chemotherapy combined with radiation therapy improves survival for patients with stage II or III rectal cancer. This population-based study was designed to assess use of these treatments in clinical practice., Patients and Methods: From the California Cancer Registry, we identified all patients diagnosed during 1996 to 1997 with stage III colon cancer (n = 1,422) and stage II or III rectal cancer (n = 534) in 22 northern California counties. To supplement registry data on adjuvant therapies and ascertain reasons they were not used, we surveyed physicians or reviewed office records for 1,449 patients (74%)., Results: Chemotherapy rates varied widely by age from 88% (age < 55 years) to 11% (age >or= 85 years), and radiation therapy varied similarly. Adjusting for demographic, clinical, and hospital characteristics, chemotherapy was used less often among older and unmarried patients, and radiation therapy was used less often among older patients, black patients, and those initially treated in low-volume hospitals. Adjusted rates of chemotherapy varied significantly (P <.01) among individual hospitals: 79% and 51%, respectively, at one SD above and below average (67%). Physicians' reasons for not providing adjuvant therapy included patient refusal (30% for chemotherapy, 22% for radiation therapy), comorbid illness (22% and 14%, respectively), or lack of clinical indication (22% and 45%, respectively)., Conclusion: Use of adjuvant therapy for colorectal cancer varies substantially by age, race, marital status, hospital volume, and individual hospital, indicating opportunities to improve care. With enhanced data on adjuvant therapies, population-based registries could become a valuable resource for monitoring the quality of cancer care.

We examined the relationship between patient age and medical care received by patients diagnosed with the following two common cancers: non-small-cell lung cancer and colorectal cancer. Controlling for the influence of sex, marital status, presence of comorbid disease, and socioeconomic status, we found that age was not related to the diagnostic tests ordered for either cancer type. However, lung cancer patients with local disease who were older than age 74 years underwent definitive surgical treatment less often than did younger patients. Few patients at any age (less than 9%) with colorectal cancer did not undergo definitive surgical treatment. Patients with regional colorectal disease who were older than 74 years of age underwent radiation therapy to the abdomen less often than did younger patients. These results add to the growing body of literature suggesting that older cancer patients are less likely to undergo the same type of care received by younger patients.

We examined the relationship between age and extent of disease at initial diagnosis as part of a population-based, prospective study documenting the patterns of care received by over 1500 newly diagnosed lung, breast, and colorectal cancer patients identified in nine Rhode Island hospitals. For each cancer site examined, no age by extent of disease relationship was observed; however, analysis by sex among lung cancer patients indicated an inverse age relationship for men. The absence of an age effect for breast cancer patients is in contrast to earlier research findings that identify a positive association between extent of disease and age at diagnosis. Past results may reflect age-related differences in patient and physician screening behavior characteristic of earlier time periods.
