Effect of air pollution on preterm birth among children born in Southern California between 1989 and 1993.

We evaluated the effect of air pollution exposure during pregnancy on the occurrence of preterm birth in a cohort of 97,518 neonates born in Southern California. We used measurements of carbon monoxide (CO), nitrogen dioxide, ozone, and particulate matter less than 10 microm (PM10) collected at 17 air-quality-monitoring stations to create average exposure estimates for periods of pregnancy. We calculated crude and adjusted risk ratios (RRs) for premature birth by period-specific ambient pollution levels. We observed a 20% increase in preterm birth per 50-microg increase in ambient PM10 levels averaged over 6 weeks before birth [RRcrude = 1.20; 95% confidence interval (CI) = 1.09-1.33] and a 16% increase when averaging over the first month of pregnancy (RRcrude = 1.16; 95% CI = 1.06-1.26). PM10 effects showed no regional pattern. CO exposure 6 weeks before birth consistently exhibited an effect only for the inland regions (RRcrude = 1.13; 95% CI = 1.08-1.18 per 3 parts per million), and during the first month of pregnancy, the effect was weak for all stations (RRcrude = 1.04; 95% CI = 1.01-1.09 per 3 parts per million). Exposure to increased levels of ambient PM10 and possibly CO during pregnancy may contribute to the occurrence of preterm births in Southern California.

Can poetry make better doctors? Teaching the humanities and arts to medical students and residents at the University of California, Irvine, College of Medicine.

The Program in Medical Humanities & Arts at the University of California, Irvine, College of Medicine has been in existence for five years. The program was implemented to enhance aspects of professionalism including empathy, altruism, compassion, and caring toward patients, as well as to hone clinical communication and observational skills. It contains elective or required curriculum across all four years of medical school and required curriculum in two residency programs, organized according to structural principles of horizontal coherence, vertical complexity, and patient care applications. The program emphasizes small-group, interdisciplinary teaching and faculty development, and is notable for learners' use of creative projects to reflect on patients and themselves. Evaluation of the program indicates a positive response among learners. More systematic studies point to increases in empathy and positive attitudes toward the humanities as tools for professional development as a result of exposure to the program curriculum. Future directions include closer collaboration with the University of California, Irvine, Schools of the Arts and Humanities, involvement of local artists and writers, and development of a graduation with distinction in humanities for medical students.

Ethnic disparity in HIV prevalence and zidovudine treatment among childbearing women and pediatric AIDS cases in California.

OBJECTIVE: To compare, by ethnicity, the prevalence of HIV and zidovudine treatment among a cross-sectional survey of childbearing women in California in 1998, and the number of pediatric AIDS cases from 1998 to 2001. METHODS: Blood specimens, collected via infant heel-stick for metabolic screening during the third quarter of 1998, were anonymously tested for HIV antibody. Positive specimens were subsequently tested for evidence of zidovudine therapy. Pediatric AIDS cases with diagnosis dates from 1998 to 2001 were obtained from the AIDS case registry. RESULTS: Of the 119 108 specimens tested, 77 (0.65 per 1000) were HIV-antibody positive. Most (37.7%) of the 77 HIV-positive specimens were from newborns of African-American mothers, followed closely by Latina mothers (35.1%). The absence of zidovudine therapy was highest for Latina and African-American women, 29.6 and 24.1%, respectively. Latino and African-American children accounted for the majority of California pediatric AIDS cases diagnosed between 1998 and 2001. CONCLUSION: Innovative approaches are needed to increase the rate of zidovudine therapy among African-American and Latina HIV-infected childbearing women. These could include a shorter-course zidovudine regimen or rapid HIV testing and counselling of women in late-term pregnancy.

Clinical nurse specialists in California: who claims the title?

State nursing practice acts granting legal authority to advanced practice nurses vary widely, with many states not recognizing clinical nurse specialists (CNSs). This survey identified characteristics of registered nurses claiming the CNS title in California. A literature-based survey tool was designed, piloted, and distributed to 209,846 nurses in California, with instructions to return the survey if the recipient self-identified as a CNS. Among the 1061 respondents, 65% were prepared with a Master's in Nursing. Most CNSs practiced in hospitals, and patients were the most frequently listed clients. CNSs overwhelmingly identified their primary role as clinical expert. Major barriers to practice included lack of public recognition and legal recognition in nursing practice acts. Significant differences were found in most characteristics between graduate-prepared and nongraduate-prepared CNSs. Variability in practice and educational preparation is not only potentially confusing to other healthcare providers and the public, but it may not serve the best interests of CNS clients.

The Southern California HMO marketplace: growth, innovation, and integration.

The 1980s have been a period of rapid growth in the Southern California HMO industry. Much of this growth is related to the emergence of network-model HMOs and, more recently, IPA-model HMOs, as a major competitive force that provides an alternative to the massive and rapidly growing Kaiser plans. The growth of the industry has been made possible by and, at the same time, has facilitated the development and growth of multispecialty medical groups and hospital-based IPAs throughout Southern California. This development has brought the HMO industry and the practice of prepaid medicine into the mainstream of health care and had led to the extensive involvement of community hospitals and independent physicians and physician groups in prepaid medicine. The coming decade will be marked by further growth and by continued integration of physician practices, hospitals, and HMOs into more efficient, high quality, vertically integrated systems of health care.

Medical malpractice in California: recent trends and future prospects.

For many years, California court decisions and legislation have often presaged national trends. The expected debate over medical malpractice should be no exception. Thus, the court decisions on third party liability and the outcome of the MICRA negotiations are important both for California and as a harbinger of future national trends.

Trends in physician participation in Medicaid. The California experience.

Physician participation rates in Medicaid vary widely across the country, and, overall, there has been a decline in recent years. We performed an evaluation in California of whether the expansion of Medicaid managed care and a physician payment increase were associated with an increase over time in the percentage of physicians caring for Medicaid patients. Surveys performed before and after these strategies were used did not reveal an increase over time in physicians' participation in California's Medicaid program. Budgetary constraints will force policy makers to confront the priorities of the Medicaid program, to question the policy objectives for physician participation in Medicaid, and to consider more far-reaching reforms in Medicaid and the overall health care system.

Use of complementary and alternative medicine by the adult membership of a large northern California health maintenance organization, 1999.

Data from general health surveys completed by random samples of adult members of a large Northern California health maintenance organization in 1996 and 1999 were used to investigate (a) the prevalence of use of 15 complementary and alternative medicine (CAM) modalities by adult members in 1999, (b) how prevalence varied by age group and gender, and (c) which modalities were increasing in popularity. While Northern California is not representative of the nation as a whole, it tends to be a harbinger of trends to come. The most widely used modalities in 1999 were herbal and other nonvitamin/nonmineral nutritional supplements, prayer/spiritual healing done by oneself, chiropractic, massage therapy, and mind-body medicine modalities. However, use of the different modalities varied significantly by age and gender, and rates of use of nutritional supplements and the manipulatives were approximately doubled, when restricted to subpopulations at high risk, for use because of relevant health conditions. There appeared to be a statistically significant, but modest increase in CAM use, mostly due to a large increase in use of nutritional supplements. Implications for how CAM use should be tracked for ambulatory care populations and the importance of addressing nutritional supplement use in ambulatory clinical care are discussed.

What should we expect from California's minimum nurse staffing legislation?

In 1999, California passed the first legislation in the United States to establish minimum staffing levels in hospitals for registered nurses (RNs) and licensed vocational nurses. The author provides estimates of the increase in RN expenditures required by this mandate, by hospital size and for regions of California. Issues related to the implementation of minimum ratios also are discussed. Attention must be paid to other staffing regulations, special concerns of rural hospitals, the possibility that minimum ratios result in lower RN staffing, and the effect of the nursing shortage on the ability of hospitals to meet requirements.

Unintentional firearm deaths in California.

We conducted a two-part study of unintentional firearm deaths in California. First, we analyzed death certificate data for the 688 unintentional firearm deaths of California residents occurring during 1977-1983. Mortality rates were 7.5 for males, 0.9 for females, 4.8 for whites, and 5.3 for blacks, all per million persons per year. Males ages 15-24 had the highest rate (17 per million persons per year). We then investigated the 131 childhood deaths in greater detail, using coroners' or medical examiners' reports. Most of these shootings occurred at a residence. Handguns were involved more frequently than predicted by their reported availability in homes in the region. Almost two thirds of child deaths resulted from head wounds, reinforcing the importance of primary prevention. At least 40% of child deaths in this study appeared in part to be attributable to defects in firearm performance or current firearm design practices, suggesting that improvements should be sought and mandated.

Putting a lid on injury costs: the economic impact of the California motorcycle helmet law.

BACKGROUND: This study analyzed the effect of California's motorcycle helmet law on injury costs. METHODS: An economic evaluation was performed using state hospital discharge data, county-level cost data, and statewide crash reports to estimate the costs, charges, and lost productivity from motorcycle injuries. Total and per person costs and changes in these costs were estimated. RESULTS: Total medical care costs were $35 million less in 1993 than in 1991, a reduction of 35%. Costs decreased for all payer categories, and 73% of the reduced hospitalization costs were attributable to reduced costs for patients with head injuries. Initial hospital costs for patients with head injuries were $18,527 compared with $10,350 for patients without head injuries. CONCLUSION: During the first 2 years of implementation of California's helmet law, there were reduced costs for injuries and fatalities and large dollar savings to the state and other payers compared with the previous year.

Factors associated with changes in occupancy rates of California short-term hospitals: an analysis of statewide hospital discharge data.

Decline in per cent occupancy of California short-term hospitals between 1969 and 1972 was due principally to an increase in bed supply that exceeded population growth. A lesser contributory cause--decline in utilization--was due entirely to decreases in length-of-stay. Analysis of data from Statewide one-week discharge surveys, carried out in 1968 and 1970, indicates the decrease in average stay was largely centered in Medicare and Medi-Cal (Medicaid) pay classes. Admissions, however, did not decrease. These declines in stay predated the introduction of special increased restrictions on access to medical care into the Medi-Cal program in April 1970. Principal results of the study indicate that in California, government supervision of payment for hospital care has operated to reduce length-of-stay, but thus far does not seem to have affected admission rates. Insofar as these results may hold for other States, they seem to implay certain conditions that may be expected to occur with an extension of National Health insurance to the general population. Chief among these is a further depression of occupancy ratios if bed supply is held constant or increases relative to population. They also imply that further substantial reduction in hospital utilization under Medicare and Medicaid must be sought in admission rates rather than length-of-stay.

In-home health services in California: some lessons for national health insurance.

Spiralling Medicare and Medicaid expenditures, recent revelations about unhealthy conditions in nursing homes, and pressure for national health insurance have led to increased interest in in-home health services as appropriate and cost-effective. Medicare and Medicaid provided some stimulus for development of in-home health services. Shortly after these programs went into effect, however, major policy decisions were made aimed at curbing utilization of in-home health services. California home health data for 1966-1973 document the effects of major policies that led to the development and decline of in-home health services under Medicare and Medicaid. A review of those policies, supported by the California data, indicate that in-home health services have been greatly restricted by historical underdevelopment and legislative and regulatory emphases. In addition, the study indicates the limitations of the kind of data currently collected and suggests data requirements necessary for future program evaluation and planning in home health.

Unlicensed foreign medical graduates in California. Social and demographic characteristics and progress toward licensure.

Foreign-born physicians graduated from foreign medical schools who were unlicensed in California are described by nationality, age, sex, location, visa status, employment, English fluency, and specialty. Over 1,210 unlicensed foreign medical graduates (FMGs) were located in California and 736 were interviewed, approximately 40% of the estimated 3,000 FMGs residing in the state. Most of the FMGs who passed the ECFMG and FLEX were young, had specialty training, had studied for the examination, had participated in review courses, and were unemployed. GMENAC projections for the number of FMGs entering the residency pool to the year 1990 may be far too low, because many unlicensed FMGs are already in the country. Two thirds of the FMGs studied came to the United States after immigration of FMGs was restricted in 1977. Many were refugees or were from countries in political upheaval. Policy issues raised are the role of FMGs in improving care to the underserved, medical standards, humanitarian issues related to the resettlement of refugees and immigrants, and the projected oversupply of physicians.

Differences in the kinds of problems consumers report in staff/group health maintenance organizations, independent practice association/network health maintenance organizations, and preferred provider organizations in California.

BACKGROUND: Little is known about the extent to which consumers have specific problems with their managed care organizations (MCOs) or whether these problems differ by type of MCO. OBJECTIVE: To estimate the prevalence at which consumers in managed care report specific problems and to assess whether rates in preferred provider organizations (PPOs), independent practice association (IPA)/network health maintenance organizations (HMOs), and staff/group HMOs differ. DESIGN: Random probability sample of insured adults weighted to reflect the underlying population in California. A computer-assisted telephone interview survey was conducted in September 1997. Logistic regression models estimate the adjusted odds of reporting each problem in the last year in IPA/network HMOs versus PPOs, IPA/network HMOs versus staff/group HMOs, and staff/group HMOs versus PPOs. SUBJECTS: One thousand two hundred one insured adults who had resided in California for > or = 12 months. MEASURES: Prevalence of 11 consumer problems in MCOs. RESULTS: Forty-two percent of adult Californians in managed care in our sample reported > or = 1 problem with their MCO in the last year. Adjusted odds that adults in IPA/ network or staff/group HMOs reported delays in getting needed care, not receiving the most appropriate or needed care, and being forced to change doctors were higher than for adults in PPOs. Adjusted odds that adults in IPA/network HMOs reported difficulty getting a referral to a specialist and difficulty selecting a doctor or hospital were higher than for adults in PPOs and staff/group HMOs. Adjusted odds that adults in staff/ group HMOs reported misunderstandings over benefits and coverage; important benefits not covered; and problems with claims, billing, or payments were lower than for adults in PPOs and IPA/network HMOs. Adjusted odds that consumers in HMOs in our sample reported any problem with their health plan was higher for those in IPA/network HMOs compared with staff/group HMOs. No differences were seen by MCO type in the rates at which consumers reported being denied care or treatment, forced to change medications, or language and communication barriers. CONCLUSIONS: Rates at which consumers report problems with managed care and the kinds of problems they report differ significantly across different types of MCOs. These findings have important implications for federal and state policy for consumer protections in managed care.

Effect of managed care on preventable hospitalization rates in California.

BACKGROUND: Hospitalization rates for ambulatory care-sensitive (ACS) conditions have emerged as a potential indicator of health care access and quality. The effect of managed care on reducing these potentially preventable hospitalizations is unknown. OBJECTIVE: To ascertain whether increases in managed care penetration were associated with changes in hospitalization rates for ACS conditions. DESIGN AND SETTING: Longitudinal analysis between 1990 and 1997 of all California hospitalizations for ACS conditions aggregated to 394 small areas. MEASURES: Association of change in ACS hospitalization rate with change in managed care penetration. RESULTS: In unadjusted analysis there was no association between the change in managed care penetration and the change in hospitalization rates for ACS conditions over time. However, in a multivariate model that controlled for changes in area demographics and hospitalization rates for marker conditions that were assumed to be stable over time, the change in managed care penetration was negatively associated with a small but statistically significant change in the ACS hospitalization rate. Each 10-point increase in percentage private managed care penetration was associated with a 3.1% decrease in the ACS hospitalization rate (95% CI, -5.4% to -0.8%) CONCLUSIONS: Overall, in California, an increase in the penetration of private managed care in a community was associated with a decrease in ACS admission rates. Additional research is needed to determine if the observed association is causal, the mechanism of the effect and whether it represents an improvement in patients' health outcomes.

Tuberculosis in children and adolescents: California, 1985 to 1995.

OBJECTIVES: To describe the epidemiology and clinical characteristics of tuberculosis (TB) among children and adolescents and to define children at risk for TB. SETTING: 4607 children 0 to 14 years of age and 1615 adolescents 15 to 19 years of age reported with TB in California. METHODS: We analyzed surveillance data reported to the California Department of Health Services TB Control Branch from 1985 through 1995. RESULTS: TB cases increased 22% among children 0 to 4 years of age and 66% among children 5 to 14 from 1985 through 1995. Case rates were highest among children 0 to 4 years of age (13/ 100000 children), but declined from 1993 to 1995, except for black children 0 to 4 years of age. Minority children 0 to 14 years of age had case rates 6- to 34-fold higher than did white children. Pulmonary TB was the most common site of disease in all age groups (71 to 82%). TB meningitis was most common in children 0 to 4 years of age (5%). Most children (64%) did not have cultures done; however, among culture-proved cases isoniazid-resistant Mycobacterium tuberculosis was isolated in 7%. Adolescents were more likely to have cavitary pulmonary disease (24%), to be foreign-born (78%) or homeless (4%) and to have an isoniazid-resistant strain isolated (13%) than were children 0 to 14 years of age (P < 0.05). CONCLUSIONS: TB in children and adolescents increased substantially in the mid-1980s and early 1990s. Pediatric TB remains a serious health problem, especially among minority children and adolescents. Our findings indicate that TB control programs need improved strategies to prevent infection and detect disease in this population.
