Breast cancer risk and provider recommendation for mammography among recently unscreened women in the United States.

BACKGROUND AND OBJECTIVE: Many women with increased breast cancer risk have not been screened recently. Provider recommendation for mammography is an important reason many women undergo screening. We examined the association between breast cancer risk and reported provider recommendation for mammography in recently unscreened women. DESIGN: Cross-sectional study using 2000 National Health Interview Survey. PARTICIPANTS: In all, 1673 women ages 40 to 75 years without cancer who saw a health care provider in the prior year and had no mammogram within 2 years. MEASUREMENTS AND ANALYSIS: We assessed breast cancer risk by Gail score and risk factors. We used multivariable logistic regression models in SUDAAN adjusted for age, race and illness burden, to examine the association between risk and reported recommendation for mammography within 1 year for all women and women ages 50 to 75 years. RESULTS: Of 1673 recently unscreened women, 29% reported a recommendation. Twelve percent of women had increased Gail risk and of these recently unscreened, high-risk women, 25% reported a recommendation. After adjustment, high-risk women were not more likely to report a recommendation than average-risk women. Results were similar for women 50 to 75 years old. No individual breast cancer factors other than age were associated with reporting a recommendation. CONCLUSIONS: Approximately 70% of recently unscreened women seen by a health care provider in the prior year reported no recommendation for mammography, regardless of breast cancer risk. This did not include women who received a recommendation and were screened. Increasing reported recommendation rates may represent an opportunity to increase screening participation among recently unscreened women, particularly for women with increased breast cancer risk.

Trends in breast conserving surgery among Asian Americans and Pacific Islanders, 1992-2000.

BACKGROUND: Breast-conserving surgery (BCS) has been the recommended treatment for early-stage breast cancer since 1990 yet many women still do not receive this procedure. OBJECTIVE: To examine the relationship between birthplace and use of BCS in Asian-American and Pacific-Islander (AAPI) women, and to determine whether disparities between white and AAPI women persist over time. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Women with newly diagnosed stage I or II breast cancer from 1992 to 2000 in the Surveillance, Epidemiology, and End Results program. OUTCOME: Receipt of breast -conserving surgery for initial treatment of stage I or II breast cancer. MAIN RESULTS: Overall, AAPI women had lower rates of BCS than white women (47% vs 59%; P<.01). Foreign-born AAPI women had lower rates of BCS than U.S.-born AAPI and white women (43% vs 56% vs 59%; P<.01). After adjustment for age, marital status, tumor registry, year of diagnosis, stage at diagnosis, tumor size, histology, grade, and hormone receptor status, foreign-born AAPI women (adjusted OR [aOR], 0.49; 95% CI, 0.32 to 0.76) and U.S.-born AAPI women (aOR, 0.77; 95% CI, 0.62 to 0.95) had lower odds of receiving BCS than white women. Use of BCS increased over time for each racial/ethnic group; however, foreign-born AAPI women had persistently lower rates of BCS than non-Hispanic white women. CONCLUSIONS: AAPI women, especially those who are foreign born, are less likely to receive BCS than non-Hispanic white women. Of particular concern, differences in BCS use among foreign-born and U.S.-born AAPI women and non-Hispanic white women have persisted over time. These differences may reflect inequities in the treatment of early-stage breast cancer for AAPI women, particularly those born abroad.

Breast carcinoma screening and risk perception among women at increased risk for breast carcinoma: results from a national survey.

BACKGROUND: The Gail model is validated to estimate breast carcinoma risk. The authors assessed the association of Gail risk scores with screening and cancer risk perception. METHODS: Using the 2000 National Health Interview Survey, the authors studied women ages 41-70 without a cancer history. Gail scores > or = 1.66% defined increased risk. The authors used logistic regression to assess associations between breast carcinoma risk and previous and recent (< or = 1 year) mammography and clinical breast examination (CBE). RESULTS: Of 6410 women, 15.7% had increased risk. High-risk women more frequently reported previous mammograms (94% vs. 85%; P < 0.0001), previous CBE (93% vs. 88%; P < 0.0001), recent mammograms (70% vs. 54%; P < 0.0001), recent CBE (71% vs. 61%; P < 0.0001), and high cancer risk perception (20% vs. 9%; P < 0.0001). However, 30% of high-risk women had not received a recent mammogram. After adjustment for sociodemographic factors, access to care factors, and cancer risk perception, high-risk women remained more likely to have received recent mammography (adjusted odds ratio [OR], 1.45, 95% confidence interval [95% CI], 1.19-1.77), recent CBE (OR, 1.32; 95% CI, 1.08-1.61]), and previous mammography than average-risk women. The authors observed an interaction between risk and age, with women ages 41-49 years more frequently reporting previous mammography (OR, 4.79; 95% CI, 1.55-4.81) than average-risk, same-age women. For women age > or = 50 years, the odds of previous mammography were similar regardless of risk. CONCLUSIONS: In a nationally representative sample, 15.7% of women had increased breast carcinoma risk using the Gail model. High-risk women perceived higher cancer risk and more often received screening. However, nearly one in three high-risk women did not receive recent screening and most of these women did not perceive increased risk.

Hospice use among Medicare managed care and fee-for-service patients dying with cancer.

CONTEXT: For most patients aged 65 years or older with cancer, hospice services are uniformly covered by Medicare. Hospice care is believed to improve care for patients at the end of life. However, few patients use hospice and others enroll too late to maximize the benefits of hospice services. OBJECTIVES: Because type of insurance may affect use, we examined whether patients with Medicare managed care insurance enrolled in hospice earlier and had longer hospice stays than patients with Medicare fee-for-service (FFS) insurance. DESIGN AND SETTING: Retrospective analysis of the last year of life using the Linked Medicare-Tumor Registry Database in 1 of 9 Surveillance, Epidemiology, and End Results program coverage areas. PATIENTS: A total of 260 090 Medicare beneficiaries aged 66 years or older diagnosed with first primary lung (n = 62 117), colorectal (n = 57 260), prostate (n = 59 826), female breast (n = 37 609), bladder (n = 19 598), pancreatic (n = 11 378), gastric (n = 9599), or liver (n = 2703) cancer between January 1, 1973, and December 31, 1996, and who died between January 1, 1988, and December 31, 1998. MAIN OUTCOME MEASURES: Time from diagnosis to hospice entry and hospice length of stay for patients enrolled in FFS vs managed care plans after adjusting for patient demographics, tumor registry, year of hospice entry, and type and cancer stage. RESULTS: Of the 260 090 patients, most were men (59%), white (85%), and enrolled in FFS (89.7%). Only 54 937 patients (21.1%) received hospice care before death. Hospice use varied by type of primary cancer ranging from 31.8% of patients with pancreatic cancer to 15.6% with bladder cancer. Managed care patients were more likely to use hospice than FFS patients (32.4% vs 19.8%, P<.001). Among hospice patients, median (interquartile range) length of stay was longer for managed care vs FFS patients (32 days [11-82] vs 25 days [9-66], P<.001). After adjustment, managed care patients had higher rates of hospice enrollment (adjusted hazard ratio [HR], 1.38; 95% CI, 1.35-1.42) and had a longer length of stay (adjusted HR, 0.91; 95% CI, 0.88-0.94) vs FFS patients. Managed care patients were less likely to enroll in hospice within 7 days of their death (18.6% vs 22.6%, P<.001) and somewhat more likely to enroll in hospice more than 180 days before death (7.8% vs 6.1%, P<.001); the results for each of the 8 cancer diagnoses were similar. Hospice enrollment and length of stay among managed care vs FFS patients differed significantly by region. CONCLUSION: Medicare beneficiaries enrolled in managed care had consistently higher rates of hospice use and significantly longer hospice stays than those enrolled in FFS. Although these differences may reflect patient and family preferences, our findings raise the possibility that some managed care plans are more successful at facilitating or encouraging hospice use for patients dying with cancer.

Barriers to hospice care among older patients dying with lung and colorectal cancer.

PURPOSE: To identify factors associated with hospice enrollment and length of stay in hospice among patients dying with lung or colorectal cancer. METHODS: We used the Linked Medicare-Tumor Registry Database to conduct a retrospective analysis of the last year of life among Medicare beneficiaries diagnosed with lung or colorectal cancer at age > or = 66 years between January 1, 1973, and December 31, 1996, in the Surveillance, Epidemiology, and End Results Program who died between January 1, 1988, and December 31, 1998. Our outcomes of interest were time from cancer diagnosis to hospice enrollment and length of stay in hospice care. We used Cox proportional hazards regression to adjust for demographic and clinical information. RESULTS: We studied elderly patients dying with lung cancer (n = 62,117) or colorectal cancer (n = 57,260). Overall, 27% of patients (n = 16,750) with lung cancer and 20% of patients (n = 11,332) with colorectal cancer received hospice care before death. Median length of stay for hospice patients with lung and colorectal cancer was 25 and 28 days, respectively. Overall, 20% of patients entered hospice within 1 week of death, whereas 6% entered more than 6 months before death. Factors associated with later hospice enrollment include being male; being of nonwhite, nonblack race; having fee-for-service insurance; and residing in a rural community. Many of these factors also were associated with shorter stays in hospice. CONCLUSION: Although use of hospice care has increased dramatically over time, specific patient groups, including men, patients residing in rural communities, and patients with fee-for-service insurance continue to experience delays in hospice enrollment.

Older Asian Americans and Pacific Islanders dying of cancer use hospice less frequently than older white patients.

PURPOSE: Cancer is the leading cause of death among Asian Americans, yet little is known about their use of hospice care. We examined hospice use by Asian patients compared with white patients, and assessed whether utilization differs among those born in the United States or abroad. METHODS: We studied Asian and white Medicare beneficiaries registered in the Surveillance, Epidemiology, and End Results (SEER) Program who died of primary lung, colorectal, prostate, breast, gastric, or liver cancer between 1988 and 1998. We used logistic regression to determine the effects of race/ethnicity and birthplace on hospice use, adjusting for demographic characteristics, managed care insurance, year of diagnosis, tumor stage at diagnosis, and tumor registry. RESULTS: Of the 184,081 patients, 5% (n = 8614) were Asian Americans, of whom 45% (n = 3847) were foreign born. Compared with whites, Asian Americans were more likely to be male, married, and enrolled in managed care. Compared with U.S.-born Asian Americans, foreign-born Asian Americans were more likely to reside in low-income areas. After adjustment, patients who were Asian American (odds ratio [OR] = 0.67; 95% confidence interval [CI]: 0.62 to 0.73) and born abroad (OR = 0.90; 95% CI: 0.86 to 0.94) were less likely to use hospice care than were white patients. These results were consistent across the six cancer diagnoses that were examined. CONCLUSION: Older Asian Americans dying of cancer, especially those who are born abroad, are less likely than white patients to use hospice care at the end of life. Additional research is needed to understand the reasons for these differences and to eliminate potential barriers to hospice care.

Hospitalization of hospice patients with cancer.

OBJECTIVES: To identify factors associated with hospitalization of elderly hospice patients with cancer and to describe their hospital experiences. DESIGN: Retrospective analysis of the last year of life. SETTING: Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. PARTICIPANTS: Medicare beneficiaries dying of lung or colorectal cancer between 1988 and 1998 who enrolled in hospice. MEASUREMENTS: Hospitalization after hospice entry. For hospitalized patients, we describe admission diagnoses, aggressiveness of care, and in-hospital death. RESULTS: Of the 23608 patients, 1423 (6.0%) were hospitalized after hospice enrollment. Hospitalization declined over time by 7.0% per year of hospice enrollment. Factors associated with higher hospitalization rates were younger age, male gender, black race/ethnicity, local cancer stage at diagnosis, and hospice enrollment within 4 months of cancer diagnosis. The most common reasons for hospital admission were lung cancer, metastatic disease, bone fracture, pneumonia, and volume depletion. Of the 1423 patients hospitalized, 34.6% received aggressive care and 35.8% died in the hospital. CONCLUSION: The rates of hospitalization for elderly hospice patients with lung or colorectal cancer appear to be declining. However, patients who are hospitalized undergo aggressive care and often die in the hospital rather than at home. This aggressive care may be consistent with changes in patients' care preferences, but could also reflect the current culture of acute care hospitals, which focuses on curative treatment and is ill-equipped to provide palliative care.
