Wait Times For Surgical And Adjuvant Radiation Treatment Of Breast Cancer In Canada And The United States: Greater Socioeconomic Inequity In America, Kevin M. Gorey
Social Work Publications
PURPOSE: The demand for cancer care has increased among aging North American populations as cancer treatment innovations have proliferated. Gaps between supply and demand may be growing. This study examined whether socioeconomic status has a differential effect on waits for surgical and adjuvant radiation treatment (RT) of breast cancer in Canada and the US.
METHODS: Ontario and California cancer registries provided 929 and 984 breast cancer cases diagnosed between 1998 and 2000 in diverse urban and rural places. Residence-based socioeconomic data were taken from censuses. Cancer care variables were reliably abstracted from health records: stage, receipt of surgery and RT, …
Associations Of Physician Supplies With Breast Cancer Stage At Diagnosis And Survival In Ontario, 1988 To 2006, Kevin M. Gorey
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.

Increased Racial Differences On Breast Cancer Care And Survival In America: Historical Evidence Consistent With A Health Insurance Hypothesis, 1975-2001, Kevin M. Gorey
Social Work Publications
PURPOSE: This study examined whether race/ethnicity had differential effects on breast cancer care and survival across age strata and cohorts within stages of disease.
METHODS: The Detroit Cancer Registry provided 25,997 breast cancer cases. African American and non-Hispanic white, older Medicare-eligible and younger non-eligible women were compared. Successive historical cohorts (1975-1980 and 1990-1995) were, respectively, followed until 1986 and 2001.
RESULTS: African American disadvantages on survival and treatments increased significantly, particularly among younger women who were much more likely to be uninsured. Within node positive disease all treatment disadvantages among younger African American women disappeared with socioeconomic adjustment.

Abstracts In High Profile Journals Often Fail To Report Harm, Enrique Bernal-Delgado, Elliot S. Fisher
Abstracts In High Profile Journals Often Fail To Report Harm, Enrique Bernal-Delgado, Elliot S. Fisher
Dartmouth Scholarship
To describe how frequently harm is reported in the abstract of high impact factor medical journals. We carried out a blinded structured review of a random sample of 363 Randomised Controlled Trials (RCTs) carried out on human beings, and published in high impact factor medical journals in 2003. Main endpoint: 1) Proportion of articles reporting harm in the abstract; and 2) Proportion of articles that reported harm in the abstract when harm was reported in the main body of the article. Analysis: Corrected Prevalence Ratio (cPR) and its exact confidence interval were calculated. Non-conditional logistic regression was used.

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, …

College of Population Health Faculty Papers
Migraine headache is a highly prevalent, chronic, episodic disorder that is associated with high direct and indirect costs. Migraine headache impacts not only patients, but also their employers due to substantial decreases in workplace productivity. Despite the prevalence and clinical and economic burdens of migraine, no national efforts to develop and implement standardized measures of quality of care have been made. The objective of this study was to collect and report on existing quality of care measures for migraine that could be suitable for quality measurement at the health-plan level. Published literature, the Agency for Healthcare Research and Quality's National …

Anemia And Blood Transfusion In The Critically Ill Patient: Role Of Erythropoietin, Howard L. Corwin
Anemia And Blood Transfusion In The Critically Ill Patient: Role Of Erythropoietin, Howard L. Corwin
Dartmouth Scholarship
Critically ill patients receive an extraordinarily large number of blood transfusions. Between 40% and 50% of all patients admitted to intensive care units receive at least 1 red blood cell (RBC) unit during their stay, and the average is close to 5 RBC units. RBC transfusion is not risk free. There is little evidence that 'routine' transfusion of stored allogeneic RBCs is beneficial to critically ill patients. The efficacy of perioperative recombinant human erythropoietin (rHuEPO) has been n demonstrated in a variety of elective surgical settings. Similarly, in critically ill patients with multiple organ failure, rHuEPO therapy will also stimulate …

Gorey, K. Association Between Socioeconomic Status And Cancer Incidence In Toronto, Ontario: Possible Confounding Of Cancer Mortality By Incidence And Survival, Kevin M. Gorey
Social Work Publications
OBJECTIVE: To observe the association between socioeconomic status (SES) and cancer incidence in a cohort of Canadians.
DESIGN: Cases of primary malignant cancer (83,666) that arose in metropolitan Toronto, Ont., from 1986 to 1993 were ascertained by the Ontario Cancer Registry and linked by residence at the time of diagnosis to a census-based measure of SES. Socioeconomic quintile areas were then compared by cancer incidence.
RESULTS: Significant associations between SES and cancer incidence in the hypothesized direction--greater incidence in low-income areas--were observed for 15 of 23 cancer sites.
CONCLUSIONS: These findings, together with the recently observed consistent pattern of significant …
