Future shock: trauma in the managed care era.

This study examines the effects of managed care on the treatment of 1724 trauma patients seen over a 2-year period at an urban Level I trauma center. Fifty-one per cent of all trauma patients were insured. Managed care plans represented 42 per cent of the insurance coverage overall, increasing from 39 per cent in the first year to 45 per cent in the second. All treatment was provided by the receiving general surgery trauma team and was rendered independent of insurance status. Eighty per cent of patients completed their hospitalization at the trauma center. Clinical outcome, transfer rates, and mortality were similar regardless of insurance type. We conclude that managed care plans represent a significant and increasing portion of the insurance coverage of trauma patients, and propose that national guidelines should be developed to guarantee quality and continuity of trauma care.

Insurance effects on US medical spending (1960-1993).

Regression results show that nearly half of 1960-1993 growth in real per capita medical spending and almost two-thirds of its 1983-1993 growth were due to ever-increasing levels of insurance coverage (the spending portion paid by third parties). Growth in coverage may have played a minor part as well; we would not rule out the standard finding that it has had a positive but relatively small effect. Viewed from a different perspective, the results imply that about two-thirds of 1960-1993 spending growth came via cost-increasing advances in medical technology resulting from: (1) commercial research and development induced by coverage levels and (2) noncommercial medical research. The remaining one-third, was due to standard factors: age-sex mix changes, income growth and coverage growth (the latter playing a small but indeterminate part).

[Status of achievement of the aseptic preparation method for total parenteral nutrition expected by physicians and nurses].

In most medical institutions, although total parenteral nutrition (TPN) should be prepared by pharmacists in sterile condition, nurses actually perform this procedure in hospital wards. The currently growing belief is that pharmacists should prepare all preparations for injection using aseptic technique. Therefore, we conducted a survey on how physicians and nurses feel about methods of preparation of TPN and other agents for injection. The results demonstrated that physicians and nurses desired pharmacists to prepare all agents for injection according to prescriptions using aseptic technique, under pharmacological control and on a 24-hours basis. Based on these results, we examined a method to realize this expectation to the extent possible in our hospital and applied it when aseptic TPN preparations were extended to include relatively stable patients requiring TPN in all hospital wards. The number of TPN preparations increased steadily. The mean number of aseptic TPN preparations after stabilization of this method was 1214 a month. A total of 48% of all TPN solutions required were prepared in aseptic condition, with an average of 4.4 vials of agents mixed per prescription. For TPN base solution, 71% of a double--bag preparation consisting of electrolytes, saccharides, and amino acids was used. It was prepared in the wards most often for the reason, "described as an unscheduled prescription". The cost of consumables required for aseptic preparations was approximately 1.7 times the insurance coverage for addition of aseptic preparations. The physicians and nurses supported the method used by the pharmacists. To ensure complete aseptic preparation of injections by pharmacists, additional pharmacists, a review on their working system, more insurance points, and a broader range of insurance coverage may be required.

Use of VA health care services by women veterans: findings from a national sample.

The Department of Veterans Affairs (VA) has a Congressional mandate but few empirical data on which to design and improve national health care services for women. We examined characteristics associated with women's current, former and non-use of the VA health care system. The study included 1,500 female veterans sampled from the Department of Veterans Affairs National Registry of Women Veterans. Women completed a 45-minute telephone survey assessing multiple domains of functional status and health service use. Using multivariate logistic regression, use of VA health care was associated with older age, more education, not being married, lower rates of insurance coverage, and poorer physical and psychological health. Women who were former users of VA health care were more likely to be ethnic minorities, have children, served less time in the military, had higher rates of insurance coverage and better physical and psychological health than current users. Prominent military experiences (e.g., service in a war-zone, exposure to trauma) were associated with former use and never using the VA health care system. Women who use VA health care are at greater economic, social, and health risk than nonusers, factors that have personal implications for the veteran as well as cost and service implications for VA. Additional research is needed to better understand the role of military experiences in women veterans' choice of health care.

Dental insurance and use of dental services.

OBJECTIVES: This article examines socioeconomic differences in insurance for dental services among Canadians aged 15 or older and factors associated with the use of dental services. DATA SOURCE: The data on dental insurance coverage and use of dental services are from the cross-sectional file of Statistics Canada's 1996/97 National Population Health Survey. The sample size of respondents aged 15 or older was 70,884. ANALYTICAL TECHNIQUES: Logistic regression analysis was used to model variables related to dental insurance coverage and to dental visits in the past year. A weighted bootstrap resampling procedure was used to derive variance estimates. MAIN RESULTS: In 1996/97, 53% of the population aged 15 or older reported having dental insurance, and 59% said they had visited a dentist in the past year. But even when they had insurance, individuals with low incomes and low educational attainment had much lower odds of visiting a dentist than those with higher incomes and more education.

Is health care use equivalent across social groups? A diagnosis-based study.

Previous studies of medical care utilization have controlled for medical need by signs or symptoms or broad disease classifications. The present study uses both symptoms and discrete diagnoses to control for medical need in order to determine if the use of ambulatory and hospital care differs by race, income, education, insurance coverage, or region. Using data from the 1976 National Health Interview Survey, we found that there were no consistent differences in the number of physician visits made in a year by these characteristics, medical need held constant. Lack of insurance coverage was associated with fewer hospitalizations in a year for five of nine chronic diseases under review. Race was associated with fewer hospitalizations for two conditions prevalent among minorities. These effects were not evident when medical need was controlled solely by signs or symptoms.

Private dental coverage: who has it and how does it influence dental visits and expenditures?

BACKGROUND: Dental insurance has had a significant impact on dentistry and dental care use. Dental insurance coverage may influence people's decisions to use dental care. During 1996, 42.9 percent of all dental expenditures were paid by private dental insurance. METHODS: The focus of this analysis is on private dental coverage, use and expenditures for the U.S. civilian community-based population during 1996. The authors provide national estimates for the population with private dental coverage, the population with a dental visit, mean number of dental visits per year and mean total expenditures for several socioeconomic and demographic categories during 1996, using Medical Expenditure Panel Survey, or MEPS, data. RESULTS: Poor and low-income people were less likely to have private dental coverage than were people with higher incomes. People without coverage at all income levels were less likely to report a dental visit than were people with coverage. When they controlled for coverage, the authors found that education at any income level did not appear to affect the likelihood of people's having multiple visits or higher expenditures. CONCLUSION: People with private coverage are more likely to visit a dentist, have a greater number of visits and have higher expenditures than are those without coverage. Private dental insurance coverage, however, is not the only determinant of dental care use. MEPS data also show that other factors play key roles. Comprehensive strategies designed to improve dental care use should keep each of these determinants in mind. PRACTICE IMPLICATIONS: While dentists may have a limited ability to influence people to seek care initially, they may be in a better position to influence the amount of care patients obtain, thereby helping make sure that patients receive the care that they need and want.

The national profile of access to medical care: where do we stand?

This paper presents analyses of recent national survey data on access to medical care. In particular, information on major access indicators and special problems associated with the economic and political climate of the 1980s collected in a 1982 national telephone survey of 6,610 United States adults and children, representing some 4,802 families, is compared with previous national surveys for key population subgroups--by age, place of residence, income, race, insurance coverage, and type of regular source of care. In general, the findings show that favorable progress has been made, but some inequities continue to persist. Some traditionally disadvantaged groups are more likely to have a regular family doctor, private insurance coverage, have been to a doctor, or had certain preventive tests and procedures than was true for them in the past. On the other hand, compared to the more economically and/or socially advantaged groups in 1982, they have still not "caught up" entirely. There also is evidence that they may be hardest hit by the exacerbation of the financial barriers to care that result from unemployment, inflation, and cutbacks in health program eligibility and benefits that have characterized the decade of the 1980s.

Effects of early health-insurance programs on European mortality and fertility trends.

In this study, we examined the mortality and fertility effects of the early health-insurance programs sponsored by several European governments in the course of the demographic transition. Three sets of effects were hypothesized, and tested with data for five countries, covering the 1875-1913 period. First, although initially small, the growing health-insurance coverage of national populations accelerated longer-term downtrends in mortality. It not only expanded access to health care, but also helped in disseminating health information and awareness. Second, widening coverage also had an opposite effect on fertility; by lowering the costs of bearing and rearing children, it acted to slow the ongoing downtrend in marital fertility. Third, there was a diverse set of interactions between the mortality and fertility effects. Improved prospects for the survival of infants and children weakened parents' motivation to produce "extra" offspring to offset losses to mortality and to insure against future losses. Child survival was further enhanced by longer intervals between births and fewer children per family. However, the reduced cost of children tended to dilute these antenatal effects. Our regression results supported the expected pattern of partial effects, but simulations were needed to gauge the total impacts of health-insurance. Two sets of simulations were conducted: first, historical simulations, which closely tracked the actual experience of each sample country; second, counterfactuals, in which health-insurance coverage was set at zero for the entire time period. Comparisons of the historical and counterfactual simulations clearly indicated that health-insurance accelerated the downtrend in mortality, but slightly retarded the secular decline in marital fertility. These effects varied in magnitude, but not in direction, among the sample countries.

Racial differences in the survival of cadaveric renal allografts. Overriding effects of HLA matching and socioeconomic factors.

BACKGROUND: The long-term survival of cadaveric renal allografts is lower in black recipients than in white recipients, although the one-year graft survival is similar in these racial groups. We sought to determine what factors account for this disparity. METHODS: We studied 100 consecutive recipients of primary cadaveric renal allografts (57 were black and 43 white) at least 1 year after transplantation (mean, 40 months); all had received identical immunosuppressive therapy. We evaluated differences in the cause and duration of end-stage renal disease, the number of pretransplantation transfusions, age, matching for HLA-A, B, and DR antigens, race of the donor, insurance coverage, and compliance to assess their effect on graft survival in both groups. RESULTS: Allograft survival after one year was significantly lower in black than in white patients (P = 0.025). According to univariate analysis, only the recipient's age at transplantation, the number of mismatches for HLA antigens, the type of insurance coverage, the source of referral for transplantation, and the degree of compliance correlated significantly with the rate of graft survival. The frequency of all variables that reduced graft survival was higher among the blacks. According to proportional-hazards analysis, the only factors contributing to a lower rate of graft survival were age of less than 30 years at transplantation (relative risk, 2.3; 95 percent confidence interval, 1.3 to 4.6), mismatches for all six HLA antigens as compared with three or fewer mismatches (relative risk, 5.6; 95 percent confidence interval, 3.3 to 9.6), and coverage by Medicaid or Medicare (relative risk, 2.2; 95 percent confidence interval, 1.5 to 3.2). Race had no additional effect. Noncompliance was more frequent among blacks (16 percent vs. 2 percent) and could substitute for insurance status in the model. CONCLUSIONS: When immunosuppression is equivalent in black and white transplant recipients, apparently race-related differences in the long-term survival of renal cadaveric allografts appear to be related to other factors that affect graft survival unfavorably, notably poor HLA matching and unfavorable socioeconomic factors.

National survey of emergency medicine resident moonlighting. SAEM Inservice Examination Survey Task Force.

OBJECTIVES: To survey emergency medicine (EM) residents regarding moonlighting practices and perceptions for clarifying: 1) resident moonlighting remuneration; 2) any association of perceived educational debt with moonlighting income and hours; and 3) perceptions related to moonlighting (including motivations, impact on resident training, and potential medicolegal difficulties). METHODS: A confidential, voluntary survey was administered to all allopathic EM residents in the United States. This written survey was provided to residents at their in-service examinations. Completed forms were anonymously returned by residents or local administrative staff to a central site where all identifiers were removed prior to mailing en mass to the investigators. Comparisons between groups were made using chi-square tests and correlations were assessed using the Pearson correlation coefficient. RESULTS: Seventy-six percent (1,826/2,407) of the surveys were returned. There was a weak correlation (r = 0.11) between educational debt and moonlighting hours for residents in the second year and above, but no association of debt with moonlighting income. Most (88%) of the residents reported that their programs permitted moonlighting. Nearly half (49%) reported that they did moonlight in some way. Most (82%) thought moonlighting provided experience not available in the residency. Only 13 (2%) respondents stated they had been sued for malpractice while moonlighting. Most (66%) moonlighting respondents stated that they moonlighted for financial reasons, with educational debt the primary motivating factor. Of the moonlighting residents, 28% were unsure of their type of malpractice insurance coverage, and 9% had no coverage at all. CONCLUSIONS: Education about EM practice matters including the risks of moonlighting should begin early in residency, because moonlighting is widespread. Residents are vulnerable to medicolegal action while moonlighting and have insufficient knowledge of their malpractice insurance coverage. Although educational debt is perceived as a strong motivating factor for moonlighting, there is only a weak relationship between educational debt and moonlighting hours.

Factors associated with walkout of patients from New South Wales hospital emergency departments, Australia.

OBJECTIVE: To explore the association between daily patient numbers, sociodemographic, clinical and system characteristics and walkout rates of patients from New South Wales (NSW) public hospital ED (without seeing a medical officer). METHODS: This was a secondary analysis of the NSW Emergency Department Data Collection, between 1 January 1999 and 31 December 2001, with a total of 4 356 323 ED attendances. Bivariate and multiple logistic regression analyses were performed to explore the relationship of walkout from ED and explanatory variables. RESULTS: About 5.7% of the patients attending in NSW public hospital ED left without seeing a doctor. The results from bivariate and multivariate analyses revealed that walkout rates significantly varied by sociodemographic and clinical characteristics of the patients. Patient groups that more likely to walk out were those aged 15-44 years, from a non-English-speaking background, Aboriginal, with lower socioeconomic status, with no private health insurance coverage and longer waiting times for triage. Patient volume in the ED showed a significant positive association with walkout rates. CONCLUSIONS: After adjusting for triage category (urgency of presentation) and triage time, patients from lower socioeconomic backgrounds and those without private health insurance coverage were more likely to leave ED without treatment. These results have important implications for Health Services. Future strategies aimed at minimizing walkouts from public hospital ED should prioritize and target factors identified in the present study.

Interest groups and health reform: lessons from California.

We review the 1992 policy choices in California for expanding health insurance coverage, focusing on the rejection of an employer mandate by legislators and voters. We analyze how interest-group politics, gubernatorial politics, and national politics shaped those choices. Although public opinion and the shift of organized medicine showed considerable support for extending health insurance coverage, the opposition of liberal and conservative groups and a foundering economy prevented a significant change in public policy. The president's health reform plan appears to address many of the unresolved concerns in California, but overcoming resistance to any kind of mandate will require skilled leadership and negotiation.

Children's health insurance status and emergency department utilization in the United States.

OBJECTIVES: Emergency department (ED) overcrowding has become a national problem. Children account for nearly 25% of overall ED visits. It has been reported that uninsured and publicly insured children are likely to visit the ED for urgent and nonurgent problems, yet it remains unclear to what extent health insurance status would influence children's overall ED utilization or ED utilization for nonurgent problems at the national level after controlling for other confounding factors. The objective of this study was to examine the effect of health insurance status on children's overall ED utilization and children's ED utilization for nonurgent problems among the general pediatric population in the United States. METHODS: Secondary analysis of the household component of the 1997 Medical Expenditure Panel Survey on 10 193 children younger than 18 years. The main outcome measures were annual overall ED utilization and ED utilization for nonurgent problems. RESULTS: During 1997, 10.8% of children were uninsured for the entire year. A total of 17.5% of children were publicly insured the entire year, whereas 55.3% of children held private insurance the entire year. There were also 16.5% of children who were insured only part of the year. Without adjusting for covariates, publicly insured children were more likely to have an ED visit during the year than both privately insured children (unadjusted odds ratio [OR]: 1.26; 95% confidence interval [CI]: 1.03-1.55) and uninsured children (unadjusted OR: 1.46; 95% CI: 1.1-1.95). The difference between publicly insured and privately insured children (adjusted OR: 0.90; 95% CI: 0.70-1.16) and between publicly insured and uninsured children (adjusted OR: 1.12; 95% CI: 0.84-1.49) became insignificant after controlling for covariates. With or without adjustments for covariates, there was no significant difference in the likelihood of having an ED visit between privately insured and uninsured children. Similar to the utilization pattern of overall ED visits, publicly insured children were more likely to have a nonurgent ED visit than both privately insured (unadjusted OR: 1.86; 95% CI: 1.36-2.53) and uninsured children (unadjusted OR: 1.81; 95% CI: 1.15-2.84). Both differences disappeared after controlling for covariates. There was no significant difference in the likelihood of nonurgent ED visits between privately insured and uninsured children with or without adjustments for covariates. CONCLUSIONS: Health insurance status was not associated with children's overall ED use or children's ED use for nonurgent problems at the national level. Our findings suggest that policy efforts in an attempt to relieve ED overcrowding conditions should look for measures beyond solely making changes in health insurance coverage for children.

Improved asthma care after enrollment in the State Children's Health Insurance Program in New York.

BACKGROUND: Uninsured children with asthma are known to face barriers to asthma care, but little is known about the impact of health insurance on asthma care. OBJECTIVES: We sought to assess the impact of New York's State Children's Health Insurance Program (SCHIP) on health care for children with asthma. DESIGN: Parents of a stratified random sample of new enrollees in New York's SCHIP were interviewed by telephone shortly after enrollment (baseline, n = 2644 [74% of eligible children]) and 1 year later (follow-up, n = 2310 [87%]). Asthma was defined by parent report using questions based on National Heart, Lung, and Blood Institute criteria. A comparison group (n = 401) who enrolled in SCHIP 1 year later was interviewed as a test for secular trends. MAIN OUTCOME MEASURES: Access (having a usual source of care [USC], unmet health needs, problems receiving acute asthma care), asthma-related medical visits, quality (continuity of care at the USC, problems receiving chronic asthma care, use of antiinflammatory medications), and asthma outcomes (change in asthma care or severity) were the main outcome measures used. Bivariate and multivariate analyses compared measures at baseline (year before SCHIP) versus follow-up (year during SCHIP). RESULTS: Three-hundred eighty-three children (14%) had asthma at baseline, and 364 had asthma at follow-up (16%). No secular trends were detected between the baseline study group and the comparison group. After enrollment in SCHIP, improvements were noted in access: lacking a USC (decrease from 5% to 1%), unmet health needs (48% to 21%), and problems getting to the USC for asthma (13 to 4%). Children had fewer asthma-related attacks and medical visits after SCHIP (mean number of attacks: 9.5 to 3.8: mean number of asthma visits: 3.0 to 1.5; hospitalizations: 11% to 3%). Quality of asthma care improved for general measures (most/all visits to USC: 53% to 94%; mean rating of provider: 7.9 to 8.8 of 10) and asthma-specific measures (problems getting to the USC for asthma care when child was well: 13% to 1%). More than two thirds of the parents at follow-up reported that both quality of asthma care and asthma severity were "better or much better" than at baseline, generally because of insurance coverage or lower costs of medications and medical care. CONCLUSIONS: Enrollment in New York's SCHIP was associated with improvements in access to asthma care, quality of asthma care, and asthma-specific outcomes. These findings suggest that health insurance improves the health of children with asthma.

The norms hypothesis and the demand for medical care.

Our results cast doubt on the validity of the norms hypothesis--that physicians treat patients in accordance with the average or modal insurance coverage in an area. The one study in the literature directly supporting this hypothesis is misspecified; when more correctly specified, it provides no support for the hypothesis. Two versions of the hypothesis are distinguished. the stronger maintains that physicians do not take account of within-area variation in insurance coverage. This version is firmly rejected by the data. A weaker version says that the physician does take account of within-area variation but that between-area differences in average coverage have an independent effect on demand. Little or no support is found for this version, but our data do not permit very powerful tests.

Health care utilization among women on O'ahu: implications for Native Hawaiian women.

Women generally seek and use more health care services than do men. Women are also more likely to encounter financial and non-financial barriers to care than do their male counterparts. These differences are accentuated among low income and minority women. We examined health care utilization patterns among women on O'ahu using survey data, and compared those patterns among Native Hawaiian and other ethnic groups. We also provide prevalence rates for several critical women's health issues by ethnic group and explore demographic predictors for health care utilization. Although the vast majority of women have seen health care providers in the last year, ethnic and socioeconomic disparities were identified, especially with respect to our Native Hawaiian female population. A pattern for Native Hawaiian women reveals among the highest rates of depression, as well as sexual/physical/emotional abuse. Alarmingly, Native Hawaiian women are also less likely to have seen a provider in the last year, less likely to have insurance coverage, and more likely to visit emergency departments. Differences by provider type served to reinforce these disparities. In order to reduce barriers to health care utilization for Native Hawaiian women--and for all women in Hawai'i--we recommend universal insurance coverage that includes screening and counseling services. Additionally, training for health care providers is essential in order to improve culturally competent, psychological assessments of health issues for women, particularly Native Hawaiian women.
