Technology Penetration of Endovascular Aortic Aneurysm Repair in Southern California

Our objective was to investigate the penetration of endovascular abdominal aortic aneurysm repair (EVAR) in the large, diverse health-care market of southern California over 3 years and to study variability in the pattern of distribution of EVAR in southern California counties by analyzing available demographic, geographic, and socioeconomic data from California state health-care databases. Information abstracted from the inpatient hospital discharge data for patients undergoing AAA repair for the years 2001, 2002, and 2003, derived from the Office of Statewide Health Planning and Development, included age, gender, race, hospitals performing EVAR, and payors for the service. Per-capita income (PCI) for the year 1999 and the population size of each county for the respective years were obtained from the U.S. Census Bureau. Data pertaining to members of the Southern California Vascular Surgical Society (SCVSS) serving the southern California region were obtained from the SCVSS membership directory. Data were categorized based on 10 counties in southern California. All the above variables were analyzed using the chi-squared test, with p < 0.05 considered significant. The proportions of EVAR for the years 2001, 2002, and 2003 were 15.4% (n = 409), 20.2% (n = 492), and 25.9% (n = 566), respectively. This is a 67.8% (p < 0.0001) increase in EVAR application in southern California since 2001. However, the proportion of EVAR varied among counties (p < 0.0001), with 457 EVARs performed in Los Angeles County and eight in Imperial County during the study period. EVAR proportion was higher in patients aged > or =65 years (p < 0.0001) and male patients (p < 0.0001). The proportion of EVAR was significantly higher in counties with more than 20 vascular surgeons available (p < 0.0001) and PCI >21,000 US$ (p < 0.0001) and in Medicare, health maintenance organization, preferred provider organization, and private insurance holders (p < 0.0001). There was a trend toward increased EVARs in counties with more than eight hospitals that performed EVAR (p = 0.0545). However, no significant difference in EVAR proportion was observed among subgroups based on race (p = 0.535) and population size (p = 0.84). Although the number and proportion of EVAR increased significantly in southern California over 3 years, the penetration of the procedure varied among counties. County affluence, payor mix, and the number of vascular surgeons/county influenced the variability. These observations suggest that economic barriers may limit access to new biomedical technology. This has implications for health-care public policy directed toward providing equal access to medical care without regard to economic status.

Illness behaviour and nationality A study of hospital care utilization by immigrants and natives in a stockholm district

Abstract Immigrants in Sweden have the same rights as natives to benefit from the national social insurance system and legally they have equal access to medical care. There are, however, a number of reasons why immigrants may exhibit different illness behaviour compared to the native population. In a record linkage study the hospital utilization during 15 months (January 1976–March 1977) by Swedes and immigrants and by Swedes and two groups of immigrants, Finns and Mediterraneans, was compared. The study population (17,004 people) was a 10% sample of the population in a Stockholm district. Compared to Swedes, immigrants more often used hospital emergency departments but less often hospital outpatient clinics. Immigrants receive more fragmented and episodic care which may lead to more emergency visits. The illness behaviour was more similar for Swedes and Finns than for Swedes and Mediterraneans. The highest utilization rates had Mediterranean women. Twenty percent of their hospital admissions were diagnosed as symptoms and illdefined causes. Institutional barriers that guard outpatient clinics and to a certain extent health centers and private physicians and make these institutions less accessible to immigrants than natives may explain some of the differences found in the study.
