The Supply Of Physicians And Care For Breast Cancer In Ontario And California, 1998 To 2006, Kevin M. Gorey, Isaac N. Luginaah, Caroline Hamm, Madhan K. Balagurusamy, Eric J. Holowaty

Social Work Publications

INTRODUCTION: We examined the differential effects of the supply of physicians on care for breast cancer in Ontario and California. We then used criteria for optimum care for breast cancer to estimate the regional needs for the supply of physicians.

METHODS: Ontario and California registries provided 951 and 984 instances of breast cancer diagnosed between 1998 and 2000 and followed until 2006. These cohorts were joined with the supply of county-level primary care physicians (PCPs) and specialists in cancer care and compared on care for breast cancer.

RESULTS: Significant protective PCP thresholds (7.75 to = 8.25 PCPs per 10 000 …

Associations Of Physician Supplies With Colon Cancer Care In Ontario And California, 1996 To 2006, Kevin M. Gorey

Social Work Publications

BACKGROUND: This study examined the differential effects of physician supplies on colon cancer care in Ontario and California. The associations of physician supplies with colon cancer stage at diagnosis, receipt of surgery and adjuvant chemotherapy, and 5-year survival were observed within each country and compared between-country.

METHODS: Random samples of Ontario and California cancer registries provided 2,461 and 2,200 colon cancer cases that were diagnosed between 1996 and 2000, and followed until 2006. Both registries included data on the stage of disease at the time of diagnosis, receipt of cancer-directed surgery, receipt of adjuvant chemotherapy, and survival. Census tract-level data …

Breast Cancer Care In Canada And The United States: Ecological Comparisons Of Extremely Impoverished And Affluent Urban Neighborhoods, Kevin M. Gorey

Social Work Publications

This study examined the differential effect of extreme impoverishment on breast cancer care in urban Canada and the United States. Ontario and California registry-based samples diagnosed between 1998 and 2000 were followed until 2006. Extremely poor and affluent neighborhoods were compared. Poverty was associated with non-localized disease, surgical and radiation therapy (RT) waits, non-receipt of breast conserving surgery, RT and hormonal therapy, and shorter survival in California, but not in Ontario. Extremely poor Ontario women were consistently advantaged on care indices over their California counterparts. More inclusive health insurance coverage in Canada seems the most plausible explanation for such Canadian …

Physician Supply And Breast Cancer Survival, Kevin M. Gorey

Social Work Publications

BACKGROUND: This study tested the hypothesis that physician supply thresholds are associated with breast cancer survival in Ontario.

METHODS: The 5-year survival of 17,820 female breast cancer patients diagnosed between 1995 and 1997 was surveilled until 2003 for all-cause mortality. Physician supply densities in 1991 and 2001 were computed for 49 Ontario regions.

RESULTS: There were independent threshold effects for general practitioners (GP; 7.25 per 10,000) and obstetrician/gynecologists (OB/GYN; 6 per 100,000) at or above which women with breast cancer were more likely to survive for 5 years. The respective risk of living in areas undersupplied with OB/GYN and GP …

Associations Of Physician Supplies With Breast Cancer Stage At Diagnosis And Survival In Ontario, 1988 To 2006, Kevin M. Gorey

Social Work Publications

BACKGROUND: The authors examined whether the supply of primary care physicians had protective effects on breast cancer stage and survival in Ontario and whether supply losses during the 1990s were associated with diminished protection.

METHODS: Random samples of the Ontario Cancer Registry, respectively, provided 879 women and 951 women who were diagnosed with breast cancer between 1988 and 1990 (followed until 1996) and 1998 and 2000 (followed until 2006), respectively. Active physician supply data (1991 and 2001) joined to each woman's census division of residence was taken from the Scott's Medical Database.

RESULTS: Protective thresholds were observed among the earlier …

Lower Adherence To Screening Mammography Guidelines Among Ethnic Minority Women In America: A Meta-Analytic Review, Rebecca J. Purc-Stephenson, Kevin M. Gorey

Social Work Publications

OBJECTIVE: This study investigates the association between ethnic minority status and receiving a screening mammogram within the past 2 years among American women over 50.

METHOD: The findings from 33 studies identified from interdisciplinary research databases (1980 to 2006) were synthesized. Separate pooled analyses compared white non-Hispanics to African Americans (28 outcomes), Hispanics (18 outcomes), and Asian/Pacific Islanders (10 outcomes).

RESULTS: Using the random effects model, results showed that African Americans were screened less than white non-Hispanics at a marginal level (OR 0.87, 95% CI 0.75, 1.00). Larger and significant discrepancies were observed for Hispanics (OR 0.65, 95% CI 0.50, …

Cancer Survival In Ontario, 1986-2003: Evidence Of Equitable Advances Across Most Diverse Urban And Rural Places, Kevin M. Gorey

Social Work Publications

OBJECTIVES: This study examined whether place and socio-economic status had differential effects on the survival of women diagnosed with breast cancer in Ontario during the 1980s and the 1990s.

METHODS: The Ontario Cancer Registry provided 29,934 primary malignant breast cancer cases. Successive historical cohorts (1986-1988 and 1995-1997) were, respectively, followed until 1994 and 2003. Diverse places were compared: the greater metropolitan Toronto area, other cities, ranging in size from 50,000 to a million people, smaller towns and villages, and rural and remote areas. Socio-economic data for each woman's residence at the time of diagnosis were taken from population censuses.

RESULTS: …
