The effects of physician supply on the early detection of colorectal cancer

BACKGROUND: Policymakers question whether there is a relationship between the number and distribution of physicians and the outcomes for important health conditions. We hypothesized that increasing primary care physician supply would be related to earlier detection of colorectal cancer. METHODS: We identified incident cases of colorectal cancer occurring in Florida in 1994 (n = 8,933) from the state cancer registry. We then obtained measures of physician supply from the 1994 American Medical Association Physician Masterfile and examined the effects of physician supply (at the levels of county and ZIP code clusters) on the odds of late-stage diagnosis using multiple logistic regression. RESULTS: For each 10-percentile increase in primary care physician supply at the county level, the odds of late-stage diagnosis decreased by 5% (adjusted odds ratio [OR] = 0.95; 95% confidence interval [CI], 0.92 - 0.99; P = .007). For each 10-percentile increase in specialty physician supply, the odds of late-stage diagnosis increased by 5% (adjusted OR = 1.05; 95% CI, 1.02-1.09; P = .006). Within ZIP code clusters, each 10-percentile increase in the supply of general internists was associated with a 3% decrease in the odds of late-stage diagnosis (OR = 0.97; 95% CI, 0.95 - 0.99; P = .006), and among women, each 10-percentile increase in the supply of obstetrician/gynecologists was associated with a 5% increase in the odds of late-stage diagnosis (OR = 1.05; 95% CI, 1.01 - 1.08; P = .005). CONCLUSIONS: If the relationships observed were causal, then as many as 874 of the 5463 (16%) late-stage colorectal cancer diagnoses are attributable to the physician specialty supply found in Florida. These findings suggest that an appropriate balance of primary care and specialty physicians may be important in achieving optimal health outcomes.     

Influence of primary care on breast cancer outcomes among medicare beneficiaries

PURPOSE We used the Surveillance Epidemiology and End Results (SEER)-Medicare database to explore the association between primary care and breast cancer outcomes. METHODS Using a retrospective cohort study of 105,105 female Medicare beneficiaries with a diagnosis of breast cancer in SEER registries during the years 1994-2005, we examined the total number of office visits to primary care physicians and non-primary care physicians in a 24-month period before cancer diagnosis. For women with invasive cancers, we examined the odds of diagnosis of late-stage disease, according to the American Joint Commission on Cancer (AJCC) (stages III and IV vs stages I and II), and survival (breast cancer specific and all cause) using logistic regression and proportional hazards models, respectively. We also explored whether including noninvasive cancers, such as ductal carcinoma in situ (DCIS), would alter results and whether prior mammography was a potential mediator of associations. RESULTS Primary care physician visits were associated with improved breast cancer outcomes, including greater use of mammography, reduced odds of late-stage diagnosis, and lower breast cancer and overall mortality. Prior mammography (and resultant earlier stage diagnosis) mediated these associations in part, but not completely. Similar results were seen for non-primary care physician visits. Results were similar when women with DCIS were included in the analysis. CONCLUSIONS Medicare beneficiaries with breast cancer had better outcomes if they made greater use of a primary care physician's ambulatory services. These findings suggest adequate primary medical care may be an important factor in achieving optimal breast cancer outcomes.     

Medicare breast surgery fees and treatment received by older women with localized breast cancer

OBJECTIVE: To determine whether area-level Medicare physician fees for mastectomy and breast conserving surgery were associated with treatment received by Medicare beneficiaries with localized breast cancer and to compare these results with an earlier analysis conducted using small areas (three-digit zip codes) as the unit of observation. DATA SOURCE: Medicare claims and physician survey data for a national sample of elderly (aged 67 or older) Medicare beneficiaries with localized breast cancer treated in 1994 (unweighted n = 1,787). STUDY DESIGN: Multinomial logistic regression analysis was used to estimate a model of treatment received as a function of Medicare fees, controlling for other area economic factors, patient demographic and clinical characteristics, physician experience, and region. PRINCIPAL FINDINGS: In 1994, average Medicare fees (adjusted for the effects of modifiers and procedure mix) for mastectomy (MST) and breast conserving surgery (BCS) were 904 dollars and 305 dollars, respectively. Holding other fees and factors fixed, a 10 percent increase in the BCS fee increased the odds of breast conserving surgery with radiation therapy relative to mastectomy to 1.34 (p = 0.02), while a 10 percent decrease in the MST fee increased the odds of breast conserving surgery with radiation therapy to 1.86 (p < 0.01). CONCLUSIONS: Among older women with localized breast cancer, financial incentives appear to influence the use of mastectomy and breast conserving surgery with radiation therapy. This finding is consistent with the hypothesis that physicians are responsive to financial incentives when the alternative procedures have clinically equivalent outcomes and the patient's clinical condition does not dominate the treatment choice. We also find that the fee effects derived from this analysis of individual data with more precise measurement of both diagnosis and treatment are qualitatively similar to the results of the small-area analysis. This suggests that the earlier study was not severely affected by ecological bias or other data limitations inherent in Medicare claims data.     

Significance of Increasing Poverty Levels for Determining Late-Stage Breast Cancer Diagnosis in 1990 and 2000

We examine the association between late-stage breast cancer diagnosis and residential poverty in Detroit, Atlanta, and San Francisco in 1990 and 2000. We tested whether residence in census tracts with increasing levels of poverty were associated with increased odds of a late-stage diagnosis in 1990 and 2000 and found that it was. To test this, we linked breast cancer cases from the Surveillance, Epidemiology, and End Results cancer registries with poverty data from the census. Tracts were grouped into low, moderate, and high poverty based on the percentage of households reporting income below the poverty level. While late-stage breast cancer rates and the number of women living in high and moderate-poverty areas declined absolutely between 1990 and 2000, estimates from our combined three-city model showed that odds of a late-stage diagnosis remained stubbornly elevated in increasingly poor areas in both years. Non-Hispanic black women faced higher odds of a late-stage diagnosis relative to non-Hispanic white women in both years. In separate regressions for each city, the odds ratios affirm that combining data across cities may be misleading. In 1990 and 2000, only women living in moderately poor neighborhoods of San Francisco faced elevated odds, while in Detroit women in both moderate- and high-poverty areas faced increased likelihood of late-stage diagnosis. In Atlanta, none of the poverty measures were significant in 1990 or 2000. In our test of physician supply on stage, an increase in the number of neighborhood primary care doctor's offices was associated with decreased odds of a late-stage diagnosis only for Detroit residents and for non-Hispanic whites in the three-city model.     

Primary care physician supply and colorectal cancer.

OBJECTIVES: Our goal was to determine if increasing primary care physician supply was associated with lower incidence and mortality rates for colorectal cancer. STUDY DESIGN: We performed an ecologic study of Florida's 67 counties, using data from the state tumor registry and the American Medical Association physician masterfile. POPULATION: Florida residents were included. OUTCOMES MEASURED: We measured age-adjusted colorectal cancer incidence and mortality rates for Florida's 67 counties during the period 1993 to 1995. RESULTS: Increasing primary care physician supply was negatively correlated with both colorectal cancer (CC) incidence (CC = -0.46; P < .0001) and mortality rates (CC = -0.29; P =.02). In linear regression that controlled for other county characteristics, each 1% increase in the proportion of county physicians who were in primary care specialties was associated with a corresponding reduction in colorectal cancer incidence of 0.25 cases per 100,000 (P < .0001) and a reduction in colorectal cancer mortality of 0.08 cases per 100,000 (P =.0008). CONCLUSIONS: Incidence and mortality of colorectal cancer decreased in Florida counties that had an increased supply of primary care physicians. This suggests that a balanced work force may achieve better health outcomes.     

Quantifying the health benefits of primary care physician supply in the United States.

This analysis addresses the question, Would increasing the number of primary care physicians improve health outcomes in the United States? A search of the PubMed database for articles containing "primary care physician supply" or "primary care supply" in the title, published between 1985 and 2005, identified 17 studies, and 10 met all inclusion criteria. Results were reanalyzed to assess primary care effect size and the predicted effect on health outcomes of a one-unit increase in primary care physicians per 10,000 population. Primary care physician supply was associated with improved health outcomes, including all-cause, cancer, heart disease, stroke, and infant mortality; low birth weight; life expectancy; and self-rated health. This relationship held regardless of the year (1980-1995) or level of analysis (state, county, metropolitan statistical area (MSA), and non-MSA levels). Pooled results for all-cause mortality suggest that an increase of one primary care physician per 10,000 population was associated with an average mortality reduction of 5.3 percent, or 49 per 100,000 per year.     

Demographic predictors of melanoma stage at diagnosis

OBJECTIVE: To examine sociodemographic characteristics as possible predictors of late-stage melanoma diagnosis. We hypothesized that late-stage diagnosis would be associated with the following: older age, male sex, unmarried status, lower educational attainment and income level, rural residence, and cigarette smoking. METHODS: We used data from the state tumor registry to study all incident cases of melanoma occurring in Florida during 1994 whose stage at diagnosis was available (N = 1884). We used multiple logistic regression to determine the effects of sociodemographic characteristics on the odds of late-stage (regional or distant metastases) diagnosis. RESULTS: There were 243 patients (12.9%) diagnosed as having melanoma that had metastasized to either regional lymph nodes or distant sites. Patients who were unmarried (odds ratio, 1.5; P= .01), male (odds ratio, 2.2; P<.001), or smokers (odds ratio, 2.2; P<.001) or who resided in communities with lower median educational attainment (odds ratio, 1.5; P= .048) had greater odds of having a late-stage diagnosis. CONCLUSIONS: To detect these cancers at an earlier stage and improve outcomes, there should be increased educational efforts directed toward physicians who treat these patients. A recognition that there may be additional risk factors for late-stage diagnosis, beyond the established risk factors, such as family history and excess sun exposure, should be included in the initial assessment. Specific public education efforts should also be targeted to these patients to increase their self-surveillance and surveillance of their partners.     

Factors associated with advanced disease stage at diagnosis in a population-based study of patients with newly diagnosed breast cancer

Breast cancer is diagnosed at a younger age and a more advanced stage in African-American women than in White women. The authors investigated the effects of several factors, including race, on stage of breast cancer in women aged 20-54 years living in Atlanta, Georgia, and diagnosed between 1990 and 1992. A total of 251 African-American and 580 White women were interviewed and their medical records reviewed. By use of polytomous logistic regression, factors possibly influencing stage and racial differences in stage were studied. In African-American women, the odds of stage III/IV breast cancer at diagnosis were almost four times the odds in White women (odds ratio = 3.79, 95% confidence interval: 2.45, 5.89) and approximately two and one-half times for stage IIA or stage IIB disease (odds ratio = 2.57, 95% confidence interval: 1.66, 3.99; odds ratio = 1.94, 95% confidence interval: 1.31, 2.86, respectively). These racial differences appeared to be largely explained by insurance status, poverty, history of mammography, method of tumor detection, and obesity. Interventions targeting these factors could potentially lower the stage at diagnosis for African-American breast cancer patients and, in doing so, improve their survival and other outcomes.     

Breast Cancer Epidemiology,Prevention and Costs of Care

Breast cancer is the most frequently diagnosed cancer in women and the second leading cause of cancer mortality. It is estimated to account for approximately 20% of all cancer expenditures, making the burden of disease relatively high. One of the most important risk factors for developing breast cancer is age; with demographic trends towards an increasing elderly population in the US, this burden is likely to increase. Recent trends in healthcare delivery have increased the emphasis on evaluating costs of providing care as well as the outcomes of that care.This paper reviews breast cancer epidemiology, primary and secondary prevention and costs of breast cancer care by stage of disease at diagnosis and type of service, and discusses implications for the development of disease management programmes. Implementation of disease management programmes, through the creation of a data infrastructure system, establishment of measurable breast health and cancer care outcomes, and programme evaluation may be an important mechanism for managed-care organisations to provide quality and cost-effective breast cancer management.     

Disparities in Late Stage Diagnosis,Treatment, and Breast Cancer-Related Death by Race,Age, and Rural Residence Among Women in Georgia

The objectives of this study were to examine the outcomes of late stage breast cancer diagnosis, receiving first course treatment, and breast cancer-related death by race, age, and rural/urban residence in Georgia. The authors used cross-sectional and follow-up data (1992–2007) for Atlanta and Rural Georgia cancer registries that are part of the National Cancer Institute's Surveillance, Epidemiology, and End Results Program (N = 23,500 incident breast cancer cases in non-Hispanic whites or non-Hispanic African Americans). Multilevel modeling and Cox proportional hazard models revealed that compared to whites, African American women had significantly increased odds of late stage diagnosis (odds ratio [OR] = 2.08, p = 0.0001) and unknown tumor stage (OR = 1.27, p = 0.0001), decreased odds of receiving radiation (OR = 0.93, p = 0.041) or surgery (OR = 0.50, p = 0.0001), and increased risk of death following breast cancer diagnosis (hazard rate ratio [HR] = 1.50, p = 0.0001). Increased age was significantly associated with the odds of late/unknown stage at diagnosis, worse treatment, and survival. Women residing in rural areas had significantly decreased odds of receiving radiation and surgery with radiation (OR = 0.59, p = 0.0001), and for receiving breast-conserving surgery compared to mastectomy (OR = 0.73, p = 0.005). Factors affecting each level of the breast cancer continuum are distinct and should be examined separately. Efforts are needed to alleviate disparities in breast cancer outcomes in hard-to-reach populations.

The impact of referral to a primary physician on cervical cancer screening

OBJECTIVES: The purpose of this study was to determine whether referral to a primary physician led to an increase in screening for cervical cancer among women enrolled in Delaware Medicaid. METHODS: Medicaid claims data were used to compare annual Papanicolaou (Pap) test rates for women referred to a primary care physician or obstetrician (n = 365) with rates for age-matched comparison women who were not referred (n = 1799). RESULTS: Thirty-eight percent of referred women and 27% of comparison women underwent Pap tests (adjusted odds ratio = 1.71; 95% confidence interval = 1.33, 2.20). CONCLUSIONS: Referral to a primary physician had a positive impact on cervical cancer screening among the study participants.     

Reproductive history and stage of breast cancer

A woman's reproductive history influences her risk of breast cancer. The authors hypothesized that reproductive history also influences stage of disease at the time of diagnosis. The authors analyzed a population-based cohort of 1.5 million Danish women born between 1935 and 1978 for whom individual information on births was available. Between 1978 and 1994, 10,790 incident cases of breast cancer in women under 60 years of age were identified. Nulliparous women compared with parous women and women with a late age at first birth compared with an early age were at significantly increased risk of being diagnosed with a large tumor and with cancer that had spread to regional lymph nodes. However, such an association was not seen for women diagnosed with a small tumor and women with cancer that had not spread to regional lymph nodes. Reproductive history did not appear to influence the time interval from first symptoms to first physician visit ("patient delay") or the time interval from first physician visit to surgery ("doctor delay"). The authors conclude that reproductive history is associated both with incidence of breast cancer and with stage of the disease at diagnosis, indicating possible influences on tumor progression and growth rate. Intensified awareness is warranted to achieve earlier diagnosis among nulliparous women and women with a late age at first childbirth, with the hope of improving their prognosis.     

Correlates of late stage breast cancer and death in a Medicaid-insured population

The authors examine how patient and insurance characteristics influence breast cancer stage at diagnosis and survival in women insured by Medicaid (N = 1,159). Two risk factors were identified for women under 65: absence of Medicaid enrollment prior to diagnosis and residency in a nursing home. Women who were not Medicaid insured prior to diagnosis were nearly 2 times more likely to have late stage disease relative to women enrolled during the month of diagnosis, and women receiving nursing home benefits had 2.47 higher odds of late stage disease relative to women who did not receive this type of care. These two variables also influenced the likelihood of death. Additional investigation is needed to evaluate breast cancer care in nursing homes and to understand what, if any, care women receive prior to Medicaid enrollment.     

Race, anthropometric factors, and stage at diagnosis of breast cancer

A recent study suggested that the greater prevalence of severe obesity among African-American women explained almost one third of the observed differences between African-American and White women in stage at diagnosis of breast cancer. The objective of this investigation was to attempt to replicate these findings in a second, larger population and to expand the analyses by including a measure of body fat distribution, the waist:hip ratio. The authors used data from a population-based study in North Carolina comprising 791 breast cancer cases (302 in African-American women and 489 in White women) diagnosed between 1993 and 1996. African-American women were more likely to have later-stage (TNM stage >/=II) breast cancer (odds ratio (OR) = 2.2; 95% confidence interval (CI): 1.6, 2.9). They also were much more likely to be severely obese (body mass index >/=32.3) (OR = 9.7; 95% CI: 6.5, 14.5) and to be in the highest tertile of waist:hip ratio (OR = 5.7; 95% CI: 3.8, 8.6). In multivariate logistic regression models, adjustment for waist:hip ratio reduced the odds ratio for later-stage disease in African-American women by 20%; adjustment for both waist:hip ratio and severe obesity reduced the odds ratio by 27%. These observations suggest that obesity and body fat distribution, in addition to socioeconomic and medical care factors, contribute to racial differences in stage at breast cancer diagnosis.     

Disease-specific and event-free survival in breast cancer patients: a hospital-based study between 1990 and 2001

BACKGROUND: In France, as in other countries, breast cancer care has changed due to therapeutic advances and organized screening programs. Can the effect of new therapeutic procedures over time be measured by health care institutions considering these changes? The present study used data from a hospital-based cancer registry to analyze changes in 5-year disease-specific and event-free survival among women with primary breast cancer over three time periods (1990-1993, 1994-1997, and 1998-2001). METHODS: All cases of primary invasive breast carcinomas, initially treated in a French Comprehensive Cancer Center between 1990 and 2001, were included. In situ breast carcinoma and male breast cancer were excluded. Cox proportional hazards models were used to analyze disease-specific and event-free survival (DSS and EFS) rates over the three time periods (1990-1993, 1994-1997, and 1998-2001). RESULTS: During the 1990-2001 period, 4,165 primary breast cancers were initially treated at the Comprehensive Cancer Center. Out of 1,012 deaths overall, 74.6% were due specifically to primary breast cancer (respectively 98% from cancer itself and 2% from treatment side effects); the cause was unknown for only 3.3% of deaths. Out of 3,810 complete remissions, 18.2% presented local, regional or metastatic relapse and 3.8% presented a second primary breast cancer. Comparison of DSS and EFS rates in a recent reporting period (1998-2001) with those in earlier time periods (1994-1997 and 1990-1993) indicated that substantial survival gains were achieved with respectively 88.4% (95% CI: 86.4-90.5), 83.2% (95% CI: 81.3-85.2), and 79.8% (95% CI: 77.4-82.2) (p<0.01) for 5-year Disease-Specific Survival, and respectively 78.3% (95% CI: 75.7-81.0), 73.9% (95% CI: 71.6-76.3), and 70.1% (95% CI: 67.4-72.8) (p<0.01) for 5-year Event-Free Survival. After adjustment for prognostic factors, period was identified as an independent predictor of survival. CONCLUSION: Survival improvement is likely to be due to changes in routine clinical practice such as an increased use of systemic adjuvant therapy over the study periods, dose modification of epirubicin in adjuvant chemotherapy for node-positive breast cancer since 1994, and organized screening programs since 1997. However the effect of possible early diagnosis and over-diagnosis biases due to screening cannot be assessed.     

Occupational exposure to metalworking fluids and risk of breast cancer among female autoworkers

BACKGROUND: Metalworking fluids (MWF) are used for lubrication during metal manufacturing. Previous studies have observed increased risks of several cancers among MWF-exposed workers. We hypothesized that MWF may be associated with risk of breast cancer because they can contain carcinogenic or endocrine-disrupting chemicals. METHODS: We conducted a case-control study nested in a cohort of 4,680 female automobile workers employed for at least 3 years between 1/1/41 and 1/1/85, with follow-up through 1994. Cases were identified using the National Death Index (NDI), Michigan cancer registries, and company records. Detailed quantitative MWF exposure data were available for each subject, although data on known breast cancer risk factors were not. RESULTS: Ninety-nine cases of breast cancer and 626 matched controls were identified. There was a weak positive association between lifetime cumulative exposure to soluble MWF and breast cancer risk, but no evidence of association with either straight or synthetic fluids. When exposure was divided into time-windows, the association was strongest for soluble MWF in the decade preceding diagnosis. Controlling for earlier exposures, there was an odds ratio of 1.18 (95% CI=1.02-1.35) per mg/m3-year of cumulative exposure to soluble MWF in this 10-year period. CONCLUSION: This hypothesis-generating study provides some preliminary evidence for an association between exposure to soluble MWF and increased risk of breast cancer. Additional studies of MWF and breast cancer, with data on known breast cancer risk factors, are warranted.     

Phytoestrogens and indicators of breast cancer prognosis

Breast cancer incidence is lower and survival is longer in Asian women residing in Japan, China, or the Philippines than Caucasian women residing in the United States. Phytoestrogen intake has been examined as a possible reason for the disparity in breast cancer incidence and survival. This study examined the association between phytoestrogen intake prior to diagnosis of breast cancer and indicators of breast cancer prognosis (tumor size, estrogen and progesterone receptor status, histological grade, lymphovascular invasion, nodal spread, and stage) in 128 women, aged 40-79 yr, newly diagnosed with invasive breast cancer. After controlling for significant confounding factors, higher intakes of phytoestrogens were associated with favorable indicators of breast cancer. In women with higher intakes of phytoestrogens, there was a 32% reduction in the odds of being diagnosed with any stage of cancer other than stage 1 (95% confidence interval, CI = 0.49-0.93; P = 0.02), a 38% reduction in odds of being diagnosed with positive lymphovascular invasion (95% CI = 0.40-0.95; P = 0.03), and a 66% increase in the odds of being diagnosed with a positive progesterone receptor (95% CI = 1.06-2.58; P = 0.03). We conclude that phytoestrogen intake prior to diagnosis may improve prognosis of breast cancer.     

Travel distance to cancer-diagnostic facilities and tumour stage

Specialisation and centralisation in healthcare systems increase patients' travel distance to cancer-diagnostic facilities but the impact of distance on tumour stage remains unclear. This study aimed to study the travel distance to cancer patient's GP and to the hospital of diagnosis and the association with tumour stage for 12 cancer types. A cohort study was conducted including cancer patients in Denmark diagnosed between 2005 and 2016 with rectum, malignant melanoma, breast, testis, oesophageal, colon, cervix, prostate, stomach, pancreatic, lung and ovary cancer (n = 256,663). Distance to each patient's GP and to the hospital of diagnosis were calculated using ArcGIS, Network Analyst. The results showed that for most easy-to-diagnose cancer types (rectum cancer, malignant melanoma, testis cancer) and cervix cancer, increasing travel distance to the hospital of diagnosis increased the odds of advanced disease at diagnosis. Contrary, increasing travel distance to the hospital was associated with decreased odds of being diagnosed with advanced disease stage among hard-to-diagnose cancer types (stomach, pancreatic, lung and ovarian cancer), and prostate cancer. Distance to the GP was overall not associated with tumour stage. The underlying mechanisms for these findings are multifaceted and might reflect differences in presentation, symptomologies and investigations used for diagnosis across cancer types.     

Hospice Care: What Services Do Patients and Their Families Receive?

OBJECTIVE: To determine the degree to which patients and families enrolled with hospice received services across key categories of palliative care, the extent of hospice-level variability in services delivered, and changes over time in services delivered. DATA SOURCE: Nationally representative sample of 9,409 discharged patients from 2,066 hospices in the National Home and Hospice Care Survey. STUDY DESIGN: Observational, cross-sectional study conducted from 1992 to 2000. The primary outcome is the receipt of services across five key categories of palliative care: nursing care, physician care, medication management, psychosocial care, and caregiver support. DATA COLLECTION: Data were obtained via interview with the hospice staff member most familiar with the patient's care, in conjunction with medical record review. PRINCIPLE FINDINGS: In 2000, 22 percent of patients enrolled with hospice received services across five key categories of palliative care. There was marked variation across hospices in service delivery. One-third of hospices provided patients and families services in one or two of the five key categories of palliative care, whereas 14 percent of hospices provided services across five key categories of palliative care. In multivariable analysis, the odds of receiving any additional hospice service was significantly greater in later compared with earlier years (odds ratio=1.10, 95 percent confidence interval 1.01-1.20). Nevertheless, the percentages of patients in 2000 receiving medication management (59 percent), respite care (7 percent), and physician services (30 percent) remained low. CONCLUSIONS: Hospice care for patients and families varies substantially across hospices. Whereas some hospices provide services across the key categories of palliative care, other hospices do not provide this breadth of services. Greater understanding of the causes of variation in service delivery as well as its impact on patient and family outcomes and satisfaction with end-of-life care is a critical subject for future research. Changes in Medicare's reimbursement policies may help hospices increase the range of services provided to patients and families.
