OBJECTIVE The aim of this study was to ascertain trends from 1995 to 2002 in general hospital discharges among adults in the United States with serious mental illness. METHODS As of 2002 the National Hospital Discharge Survey collected data on approximately 327,000 discharges from 445 hospitals. ICD-9-CM codes were used to identify the discharges between(More)
BACKGROUND Mixed methods research has emerged alongside qualitative and quantitative approaches as an important tool for health services researchers. Despite growing interest, among health services researchers, in using mixed methods designs, little has been done to identify the procedural aspects of doing so. PURPOSE To describe how mixed methods(More)
OBJECTIVE To examine the likelihood of enrollees in the Nebraska Every Woman Matters program being screened for breast and cervical cancer. METHODS We explored the relationship between sociodemographic characteristics and receiving cancer screening services. RESULTS Older and Native American women were more likely than younger and White women to have(More)
OBJECTIVES To examine cardiovascular disease (CVD) risk factors and changes in the 10-year coronary heart disease (CHD) risk factors in women who participated in the WISEWOMAN program in Nebraska. METHODS Data for analysis were available for a total of 10,739 women who received CVD screening between September 2002 and December 2004. We examined the(More)
CONTEXT Hospitalization due to ambulatory care sensitive conditions (ACSCs) is often used as an indicator for measuring access to primary care. Rural health clinics (RHCs) provide basic primary care services for rural residents in health professional shortage areas (HPSAs). The relationship between RHCs and ACSCs is unclear. PURPOSE The purpose of this(More)
CONTEXT Few studies have examined hospitalization patterns among the uninsured, especially from the perspective of rural and urban differences. PURPOSE To examine whether the patterns of uninsured hospitalizations differ in rural and urban hospitals and to identify the most prevalent and costly diagnoses among uninsured hospitalizations. METHODS We(More)
Despite the use of quantitative and qualitative data in trauma research and therapy, mixed methods studies in this field have not been analyzed to help researchers designing investigations. This discussion begins by reviewing four core characteristics of mixed methods research in the social and human sciences. Combining these characteristics, the authors(More)
To provide a global analysis of the influence of Tau neuropathology at molecular level, we used cDNA arrays representing 8832 genes to determine the mRNA expression profile in transgenic mice expressing the most common frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) Tau mutation (P301L) (Nat. Genet. (2000) 402). Genes whose(More)
Using data from the 2002 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, we examined the magnitude, variation, and determinants of rural hospital resource utilization associated with hospitalizations due to ambulatory care sensitive conditions (ACSCs). An estimated $9.5 billion in charges incurred in rural hospitals nationwide in(More)
This study used data from the National Hospital Discharge Survey to examine secular trends and regional variation in hospitalization rates for congestive heart failure. The hospitalization rate for congestive heart failure rose significantly between 1995 and 2004 for adults aged 35 to 64 years. This trend was particularly marked in the West region (from(More)
