In a comparison of rates of acquired immunodeficiency syndrome (AIDS)-defining malignancies (ADMs) for 1989-1996 versus 1997-2002, we found a decrease in ADMs (rate ratio, 0.31; P<.0001) and a significant increase in non-AIDS-defining malignancies (non-ADMs; rate ratio, 10.87; P<.0002). The mean CD4 cell count was lower among patients with ADMs than among those with non-ADMs. A longer duration of survival during highly active antiretroviral therapy might explain the increasing incidence of non-ADMs.

Temporal Trends And Factors Associated With Extent Of Delay To Hospital Arrival In Patients With Acute Myocardial Infarction: The Worcester Heart Attack Study, Jorge Yarzebski, Robert Goldberg, Joel Gore, Joseph Alpert
Jorge L. Yarzebski
Factors associated with delay to hospital arrival after the onset of symptoms suggestive of acute myocardial infarction (AMI) were examined in the late 1960s and 1970s, but recent data concerning these characteristics are limited. The purpose of the present study was to examine overall and temporal distributions of the extent of patients' delay from the time of onset of AMI symptoms to hospital arrival and factors associated with delay in seeking medical care from a multihospital, population-based perspective. Review of medical records was undertaken of patients hospitalized with a discharge diagnosis of AMI in 16 teaching and community hospitals in …

Sex Differences In 2-Year Mortality After Hospital Discharge For Myocardial Infarction, Viola Vaccarino, Harlan Krumholz, Jorge Yarzebski, Joel Gore, Robert Goldberg
Jorge L. Yarzebski
BACKGROUND: An interaction between sex and age is thought to affect hospital mortality after myocardial infarction; younger, but not older, women have been shown to have higher mortality rates than men. It is currently unknown whether findings are similar after hospital discharge. OBJECTIVE: To determine whether an interaction between sex and age affects 2-year mortality after myocardial infarction. DESIGN: Community-based prospective cohort study. SETTING: 16 community hospitals serving the Worcester, Massachusetts, metropolitan area. PATIENTS: 6826 patients who survived hospitalization for acute myocardial infarction during ten 1-year periods between 1975 and 1995. MEASUREMENTS: Mortality 2 years after hospital discharge. RESULTS: The …

Jorge L. Yarzebski
BACKGROUND: Stroke is the third leading cause of death in Puerto Rico. We examined the pre-hospital phase, management and case-fatality-rates (CFR) of patients discharged with acute stroke from the Carolina University of Puerto Rico Hospital during 2007.
METHODS: Trained personnel collected information on demographics, delay-time, mode-of-transportation, management, and mortality from all medical records. STATAa was utilized to conduct univariate comparison of demographics, mode-of-transportation, therapeutics and diagnostic characteristics. Logistic regression analysis assessed cohort effect and controlled for confounders.
RESULTS: The average age was 69.1 years, and 53% were males. The average delay between onset of symptoms suggestive of stroke and arrival …

Crawford, Christine Cote, Joseph Couto, Mehmet Daskiran, Candace Gunnarsson, Kara Haas, Sara Haas, Somesh C Nigam, Rob Schuette, Joseph Yaskin
College of Population Health Faculty Papers
The study objective was to facilitate investigations by assessing the external validity and generalizability of the Centricity Electronic Medical Record (EMR) database and analytical results to the US population using the National Ambulatory Medical Care Survey (NAMCS) data and results as an appropriate validation resource. Demographic and diagnostic data from the NAMCS were compared to similar data from the Centricity EMR database, and the impact of the different methods of data collection was analyzed. Compared to NAMCS survey data on visits, Centricity EMR data shows higher proportions of visits by younger patients and by females. Other comparisons suggest more acute …
Prevalence Of Obesity, Type Ii Diabetes Mellitus, Hyperlipidemia, And Hypertension In The United States: Findings From The Ge Centricity Electronic Medical Record Database., Albert G Crawford, Christine Cote, Joseph Couto, Mehmet Daskiran, Candace Gunnarsson, Kara Haas, Sara Haas, Somesh C Nigam, Rob Schuette
Prevalence Of Obesity, Type Ii Diabetes Mellitus, Hyperlipidemia, And Hypertension In The United States: Findings From The Ge Centricity Electronic Medical Record Database., Albert G Crawford, Christine Cote, Joseph Couto, Mehmet Daskiran, Candace Gunnarsson, Kara Haas, Sara Haas, Somesh C Nigam, Rob Schuette
College of Population Health Faculty Papers
This study analyzed GE Centricity Electronic Medical Record (EMR) data to examine the effects of body mass index (BMI) and obesity, key risk factor components of metabolic syndrome, on the prevalence of 3 chronic diseases: type II diabetes mellitus, hyperlipidemia, and hypertension. These chronic diseases occur with high prevalence and impose high disease burdens. The rationale for using Centricity EMR data is 2-fold. First, EMRs may be a good source of BMI/obesity data, which are often underreported in surveys and administrative databases. Second, EMRs provide an ideal means to track variables over time and, thus, allow longitudinal analyses of relationships …

Indirect Costs Associated With Surgery For Low Back Pain-A Secondary Analysis Of Clinical Trial Data., Reginald Fayssoux, Neil I Goldfarb, Alexander R Vaccaro, James Harrop
College of Population Health Faculty Papers
This study examines the indirect costs associated with surgery for axial low back pain using data obtained from a prospective multicenter clinical trial that compared Charité artificial disc replacement with anterior lumbar interbody fusion using iliac crest bone graft. While 75% of study subjects reported full- or part-time employment prior to surgery, this percentage dropped to 45% at 6 weeks postoperatively. Return to preoperative employment levels occurred at approximately 6 months postoperatively. Two years after surgery, employment levels were 16% higher than preoperative levels. Lost productivity related to absenteeism resulted in lost wages averaging $2884 per patient during the first …
Income And Long-Term Breast Cancer Survival: Comparisons Of Vulnerable Urban Places In Ontario And California, Kevin M. Gorey
Income And Long-Term Breast Cancer Survival: Comparisons Of Vulnerable Urban Places In Ontario And California, Kevin M. Gorey
Social Work Publications
Effects of socioeconomic status on the long-term survival of 808 women with node-negative breast cancer in Canada and the United States were observed. Ontario and California samples diagnosed between 1988 and 1990 were followed until 2006. Socioeconomic data were taken from population censuses. Compared with their California counterparts, residents of low-income urban areas in Ontario experienced a significant 15-year survival advantage (RR = 1.66 [95% CI: 1.00, 2.76]). In these and other vulnerable, lower-middle- to working-class neighborhoods, significantly more Ontario residents gained access to adjuvant radiation therapy (RR = 1.75 [1.21, 2.53]) which seemed associated with better long-term survival (RR …
Breast Cancer Care In Canada And The United States: Ecological Comparisons Of Extremely Impoverished And Affluent Urban Neighborhoods, Kevin M. Gorey
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
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 …

Breast Cancer Survival In Ontario And California, 1998-2006: Socioeconomic Inequity Remains Much Greater In The United States, Kevin M. Gorey
Social Work Publications
This study re-examined the differential effect of socioeconomic status on the survival of women with breast cancer in Canada and the United States. Ontario and California cancer registries provided 1,913 cases from urban and rural places. Stage-adjusted cohorts (1998-2000) were followed until 2006. Socioeconomic data were taken from population censuses. SES-survival associations were observed in California, but not in Ontario, and Canadian survival advantages in low-income areas were replicated. A better controlled and updated comparison reaffirmed the equity advantage of Canadian health care.
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.
CONCLUSIONS: Growth …

Biomedical Scientists' Perception Of The Social Sciences In Health Research, Mathieu Albert, Suzanne Laberge, Brian Hodges, Glenn Regehr, Lorelei Lingard
Lorelei Lingard
The growing interest in interdisciplinary research within the Canadian health sciences sector has been manifested by initiatives aimed at increasing the involvement of the social sciences in this sector. Drawing on Bourdieu's concept of field and Knorr-Cetina's concept of epistemic culture, this study explores the extent to which it is possible for the social sciences to integrate into, and thrive in, a field in which the experimental paradigm occupies a hegemonic position. Thirty-one semi-structured interviews were conducted to explore biomedical scientists' receptiveness toward the social sciences in general and to qualitative research in particular. We found that these respondents exhibited …

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: …

To examine how a group practice used organizational strategies rather than provider-level incentives to achieve savings for health maintenance organization (HMO) compared to fee-for-service (FFS) patients. A large group practice with a group model HMO also treating FFS patients. Data sources were all patient encounter records, demographic files, and clinic records covering 3.5 years (1986-1989). The clinic's procedures to record services and charges were identical for FFS and HMO patients. All FFS and HMO patients under age 65 who received any outpatient services during approximately 100,000 episodes of the seven study illnesses were eligible.

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 …

We compared the validity of hospital admission and length of stay reports from patients, outpatient providers, and hospitals, and we examined possible sources of error. Data were collected from people enrolled in a randomized trial of treatment for severe mental illness and substance use disorders, from community mental health centers (CMHCs), and from hospitals. Reports for each of the 74 study participants covered two-year time periods beginning and ending at various times between 1989 and 1993. We compared reports from the various sources and constructed a hybrid with data from all three sources. Using parametric and non-parametric statistics, we compared …
