Women’S Health Disparities And Midwifery Care: Spotlight On Massachusetts, Dorothy Hiersteiner

Publications from the Center for Women in Politics and Public Policy

As a result of Massachusetts’ 2006 health insurance coverage law, there has been a significant decrease in the uninsurance rate for women of color. Access to and use of health care for all women in the Commonwealth has also increased. Despite these coverage and access gains, major racial/ethnic disparities in health conditions and outcomes still exist among women, especially in the use and quality of prenatal care, the occurrence of preterm and low birth weight births, and infant mortality rates. The proportion of Massachusetts births that were cesarean deliveries in 2007 was 8% higher than the national rate. Compared to …

Jorge L. Yarzebski

OBJECTIVES: Obesity is associated with an increased risk of heart failure (HF). Among patients presenting with acute HF, however, differences in clinical characteristics, treatment regimens, and short-term prognosis of varying weights are largely unknown, particularly from a broader population-based perspective. METHODS: A total of 3722 patients admitted with acute HF to 11 greater Worcester (Massachusetts, USA) hospitals during 1995 and 2000 were categorized as being lean (n = 216), normal weight (n = 1465), overweight (n = 1007), or obese (n = 1034) at the time of hospitalization. RESULTS: Obese patients with decompensated HF were significantly younger (mean age = …

Jorge L. Yarzebski

OBJECTIVES: To describe sex differences in symptom presentation after acute myocardial infarction (AMI) while controlling for differences in age and other potentially confounding factors. BACKGROUND: Although several studies have examined sex differences in diagnosis, management, and survival after AMI, limited data exist about possible sex differences in symptom presentation in the setting of AMI. METHODS: Community-based study of patients hospitalized with confirmed AMI in all 16 metropolitan Worcester, Mass., hospitals (1990 census population = 437,000). Men (n = 810) and women (n = 550) hospitalized with validated AMI in 1986 and 1988 comprised the study sample. RESULTS: After simultaneously controlling …

The Impact Of The Stent Era On The Management Strategy For Acute Myocardial Infarction: A Population-Based Perspective, Harold Dauerman, Robert Goldberg, Jorge Yarzebski, Darleen Lessard, Joel Gore

Jorge L. Yarzebski

We determined trends in the use of invasive diagnostic and revascularization strategies from a multihospital community-wide perspective for patients suffering acute myocardial infarction (AMI). Comparing 3,824 patients treated in the prestent era (1986-1993) to 1,915 patients hospitalized during the stent era (1995-1997), there was a significant increase in the use of invasive procedures and revascularization techniques across a broad spectrum of AMI patients during their index hospitalization. This resulted in a higher-risk profile of patients referred for invasive management of AMI in the stent era. Cathet. Cardiovasc. Intervent. 51:255-258, 2000.

Jorge L. Yarzebski

BACKGROUND: Recent randomized clinical trials have suggested a benefit of an invasive management strategy in patients with acute coronary syndromes. However, the broader use and impact of the invasive management approach has not been established for patients with acute coronary syndromes beyond the relatively narrow patient populations studied in randomized, clinical trials. METHODS: Residents of the Worcester, Mass, area who were hospitalized with non-Q-wave acute myocardial infarction (AMI) at all area hospitals in 5 annual periods between 1990 and 1997 comprised the sample of interest (n = 2436). We examined the extent of use of an invasive versus a conservative …

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 …
