Health care for children and youth in the United States: 2002 report on trends in access, utilization, quality, and expenditures.

OBJECTIVE: To examine changes in insurance coverage, health care utilization, perceived quality of care, and expenditures for children and youth in the United States using data from 1987-2001. METHODS: Three national health care databases serve as the sources of data for this report. The Medical Expenditure Panel Survey (1996-2001) provides data on insurance coverage, utilization, expenditures, and perceived quality of care. The National Medical Expenditure Survey (1987) provides additional data on utilization and expenditures. The Nationwide Inpatient Sample (1995-2000) from the Healthcare Cost and Utilization Project provides information on hospitalizations. RESULTS: The percent of children uninsured for an entire year declined from 10.4% in 1996 to 7.7% in 1999. Most changes in children's health care occurred between 1987 and the late 1990s. Overall utilization of hospital-based services has declined significantly since 1987, especially for inpatient hospitalization. Several of the observed changes from 1987 varied significantly by type of health insurance coverage, poverty status, and geographic region. Quality of care data indicate some improvement between 2000 and 2001, which varies by insurance coverage. Overall, mean length of stay of hospitalizations did not change significantly from 1995 to 2000, but changes in the prevalence of hospitalizations and the length of stay associated with age-specific diagnoses were evident during this time period. CONCLUSIONS: Health care for children and youth has changed significantly since 1987, with most of the changes occurring between 1987 and 1996. Insurance coverage has improved, the site of care has shifted toward ambulatory sites, hospital utilization has declined, and expenditures on children as a proportion of total expenditures have decreased. Variation in these changes is evident by insurance status, poverty, and region.

Forging a poison prevention and control system: report of an Institute of Medicine committee.

The Committee forged a vision for a national poison prevention and control system that broadly integrates the current network of poison control centers with state and local public health departments responsible for monitoring populations. Implementing the Committee's recommendations, however, will require leadership from the Congress and the federal agencies to whom the report is addressed: HRSA and CDC. The next steps include amendments to existing legislation to establish the national system and to secure federal funding to assure stability of the system and systematic oversight by the federal agencies to hold all parties accountable for the performance of the system.

Health care for children and youth in the United States: annual report on patterns of coverage, utilization, quality, and expenditures by income.

OBJECTIVES: To examine differences by income in insurance coverage, health care utilization, expenditures, and quality of care for children in the United States. METHODS: Two national health care databases serve as the sources of data for this report: the 2000-2002 Medical Expenditure Panel Survey (MEPS) and the 2001 Nationwide Inpatient Sample (NIS) from the Healthcare Cost and Utilization Project (HCUP). In the MEPS analyses, low income is defined as less than 200% of the federal poverty level and higher income is defined as 200% of the federal poverty level or more. For the HCUP analyses, median household income for the patient's zip code of residence is used to assign community-level income to individual hospitalizations. RESULTS: Coverage. Children from low-income families were more likely than children from middle-high-income families to be uninsured (13.0% vs 5.8%) or covered by public insurance (50.8% vs 7.3%), and less likely to be privately insured (36.2% vs 87.0%). Utilization. Children from low-income families were less likely to have had a medical office visit or a dental visit than children from middle-high-income families (63.7% vs 76.5% for office-based visits and 28.8% vs 51.4% for dental visits) and less likely to have medicines prescribed (45.1% vs 56.4%) or have utilized hospital outpatient services (5.2% vs 7.0%), but more likely to have made trips to the emergency department (14.6% vs 11.4%). Although low-income children comprise almost 40% of the child population, one quarter of total medical expenditures were for these children. Hospital Discharges. Significant differences by community-level income occurred in specific characteristics of hospitalizations, including admissions through the emergency department, expected payer, mean total charges per day, and reasons for hospital admission. Leading reasons for admission varied by income within and across age groups. Quality. Low-income children were more likely than middle-high-income children to have their parents report a big problem getting necessary care (2.4% vs 1.0%) and getting a referral to a specialist (11.5% vs 5.3%). Low-income children were at least twice as likely as middle-high-income children to have their parents report that health providers never/sometimes listened carefully to them (10.0% vs 5.1%), explained things clearly to the parents (9.6% vs 3.4%), and showed respect for what the parents had to say (9.2% vs 4.2%). Children from families with lower community-level incomes were more likely to experience ambulatory-sensitive hospitalizations. Racial/Ethnic Differences Between Income Groups. Use and expenditure patterns for most services were not significantly different between low- and middle-high-income black children and were lower than those for white children. CONCLUSIONS: While health insurance coverage is still an important factor in obtaining health care, the data suggest that efforts beyond coverage may be needed to improve access and quality for low-income children overall and for children who are racial and ethnic minorities, regardless of income.

Improving imperfect data from health management information systems in Africa using space-time geostatistics.

BACKGROUND: Reliable and timely information on disease-specific treatment burdens within a health system is critical for the planning and monitoring of service provision. Health management information systems (HMIS) exist to address this need at national scales across Africa but are failing to deliver adequate data because of widespread underreporting by health facilities. Faced with this inadequacy, vital public health decisions often rely on crudely adjusted regional and national estimates of treatment burdens. METHODS AND FINDINGS: This study has taken the example of presumed malaria in outpatients within the largely incomplete Kenyan HMIS database and has defined a geostatistical modelling framework that can predict values for all data that are missing through space and time. The resulting complete set can then be used to define treatment burdens for presumed malaria at any level of spatial and temporal aggregation. Validation of the model has shown that these burdens are quantified to an acceptable level of accuracy at the district, provincial, and national scale. CONCLUSIONS: The modelling framework presented here provides, to our knowledge for the first time, reliable information from imperfect HMIS data to support evidence-based decision-making at national and sub-national levels.

Dealing with the dangers of fear: the role of risk communication.

Among the many lessons of the homeland terrorist attacks of 2001 was that fear has powerful public health implications. People chose to drive instead of flying, thereby raising their risk of injury or death. Thousands took broad-spectrum antibiotics to prevent possible anthrax infections, thereby accelerating antimicrobial resistance. Such potentially harmful actions were taken by people seeking a sense of safety because they were afraid. This essay argues for greater emphasis on risk communication to help people keep their fears in perspective. Effective communication, not only through what the government says but implicit in the actions it takes, empowers people to make wiser choices in their own lives, and to support wise choices by society in applying limited resources to maximize public and environmental health.

Leveraging the nation's anti-bioterrorism investments: foundation efforts to ensure a revitalized public health system.

The emerging potential threats of bioterrorism combined with critical existing epidemics facing the United States call for immediate and urgent attention to the U.S. public health system. The foundation world is helping to answer that call and is sounding the alarm that our health defenses must be able to do "double duty" to protect us from the full spectrum of modern health threats. This Special Report presents a selective sample of recent and ongoing grant activities designed to revitalize and modernize the public health infrastructure, which is vital to protecting the nation's health and ensuring its safety.

The predictive accuracy of the New York State coronary artery bypass surgery report-card system.

We examined the impact of New York State's public reporting system for coronary artery bypass surgery fifteen years after its launch. We found that users who picked a top-performing hospital or surgeon from the latest available report had approximately half the chance of dying as did those who picked a hospital or surgeon from the bottom quartile. Nevertheless, performance was not associated with a subsequent change in market share. Surgeons with the highest mortality rates were much more likely than other surgeons to retire or leave practice after the release of each report card.

The value of health care information exchange and interoperability.

In this paper we assess the value of electronic health care information exchange and interoperability (HIEI) between providers (hospitals and medical group practices) and independent laboratories, radiology centers, pharmacies, payers, public health departments, and other providers. We have created an HIEI taxonomy and combined published evidence with expert opinion in a cost-benefit model. Fully standardized HIEI could yield a net value of dollar 77.8 billion per year once fully implemented. Nonstandardized HIEI offers smaller positive financial returns. The clinical impact of HIEI for which quantitative estimates cannot yet be made would likely add further value. A compelling business case exists for national implementation of fully standardized HIEI.

Analysis of prevalence, triggers, risk factors and the related socio-economic effects of childhood asthma in the Student Lung Health Survey (SLHS) database, Canada 1996.

The purpose of this study was to provide information to improve the management of childhood asthma in Canada. The Student Lung Health Survey (SLHS) was conducted as a stratified and multi-staged cluster survey across Canada in 1996. It included a total of 136 public, private and separate schools in nine health units. The target study population was schoolchildren aged 5 to 19 years. Among all 5-19 years old students, the prevalence of asthma was 13.0%, with the prevalence for males being higher than for females, the adjusted Odds Ratio (OR) was 1.17, (95% CI 1.14-1.19) for males, in comparison with females. The prevalence in the 15-19 age group was higher than that in the 5-9 and 10-14 age group in females, but it was higher in the 5-9 and 10-14 age group than in the 15-19 age group in males. The mean delay from the onset of symptoms to time of first diagnosis was 1, 0.4 and 0.3 years for the 1-4, 5-9 and 10-14 age group respectively. However, there was no delay in the 15-19 group. The prevalence of asthma in Prince Edward Island (17.9%), Halifax (17.1%), and Kingston (16.1%) was higher than that in Saskatoon (10.0%). Sherbrooke (9.7%) and Kelowna (11.9%). The proportion of asthma for students who smoked more than 11 cigarettes per day (OR = 1.41), were exposed to passive smoke in home (OR = 7.29), in car (OR = 4.71), and in school (OR = 4.24) or had a family income less than CAN$40,000 (OR = 1.19), was significantly higher than groups without those factors. Risk factors and socio-economic status such as living conditions and environment, pets or plants in the home, parental education levels also affected the morbidity of asthma. The results of the SLHS study demonstrated the serious burden of childhood asthma, and asthma triggers, living and environmental conditions and lifestyle influence the prevalence and the effects of childhood asthma diagnosis, treatment, and education in Canada. Asthma is still a serious chronic condition for students and it influences their academic performance and their quality of life. The diagnostic methods and the practice guidelines for asthma control are useful for preventing and controlling asthma. These findings provide indications of interventions are being used for the control of asthma in Canada.

Youth injury in Israel: an appeal for change.

Unintentional injury in children and adolescents have raised public health concerns in recent years, because it is the leading cause of death, a physical burden for the injured person, an emotional and social burden for the families together with an economic burden for society. The National Center for Children's Safety and Health in Israel was established in 1995 at the Schneider Children's Medical Center in order to focus on prevention of childhood and adolescent injury and safety. Over these years data has been collected from the Central Bureau of Statistics, the Ministry of Health, the National Trauma Register, Police and the National Poison Center in order to look for trends and develop strategies for intervention. These efforts, together with the active prevention programs that have been established, resulted in a national report (1) presented to the Minister of Health and other policy makers in 2003. The current situation of youth injuries in Israel, which over the years have not shown any improvement, necessitates a new agenda with a focus on prevention and collaboration between various ministries and agencies in order to implement it. The report alone cannot have an impact upon youth safety, but we hope that it will provide an impetus for developing youth safety strategies and programs based on data. We also believe there is a need for long-term monitoring and follow-up of youth injury trends in Israel.

[Software program to systematize data for planning public health actions].

OBJECTIVE: To describe and evaluate a software program to provide basic health care teams with primary health services data. METHODS: It was described the PACOTAPS (software program for primary health care), developed using Visual Basic 5.0, and secondary data and outpatient care demand modules were tested in a basic health care unit in Pelotas, Brazil. Age/gender structure of the reference population was obtained from secondary data. Outpatient care demand allowed the characterization of all 4,170 visits carried out in a month by analyzing Outpatient Care Files. RESULTS: Age and gender distribution as well as main diagnoses and referrals were identified for all patients seen at the health care unit. In addition, there were detected differences among the health care centers due to either different organization and care models or as a result of different actual needs of improvement in patient register systems. CONCLUSIONS: PACOTAPS, a user-friendly software program, can contribute to health care unit management evaluation within the national Unified Health System (SUS). The availability of an electronic tool combining resources allows decision making in healthcare facilities, and even at municipal health policy level, to be based on more adequate and effective data.

[Data and the process of formulating health policies].

OBJECTIVE: To evaluate the use of the available information systems in decision-making process involving municipalities' health services, since technical scientific information is becoming an important tool for managers' decision-making both in the private and public sectors. METHODS: Four case studies were undertaken in the state of Sao Paulo between 1998 and 2000. The municipalities included in this study varied in size and in terms of the of complexity of their health systems. Research involved the use of both quantitative (survey of epidemic, demographic, economic-financial and social indicators) and qualitative methods (interviews with key actors and focus group). "Triangulation" was adopted in the analysis in order to establish an articulation among the diverse sources of data and methodological procedures utilized. RESULTS: The strategy of implementation of the Unified Health System (SUS) in itself implies in a pattern of consumption of information already available in large data banks within public institutions and local production of information concerning, primarily, the financial dimension of the city or district, whatever its size, the complexity of the local health system and the type of health administration. CONCLUSIONS: The information available on the data banks are, in general, considered outdated with respect to the immediate needs of local health managers. The equipment infrastructure and training of human resources in health data management were considered precarious for use in the decision-making process.

Comparative geographic concentrations of 4 sexually transmitted infections.

OBJECTIVES: We measured and compared the concentration of primary and secondary syphilis, gonorrhea, chlamydial infection, and genital herpes in a large county with urban, suburban, and rural settings. METHODS: We geocoded sexually transmitted infections reported to King County, Washington health department in 2000-2001 to census tract of residence. We used a model-based approach to measure concentration with Lorenz curves and Gini coefficients. RESULTS: Syphilis exhibited the highest level of concentration (estimated Gini coefficient = 0.68, 95% confidence interval [CI] = 0.64, 0.78), followed by gonorrhea (estimated Gini coefficient=0.57; 95% CI=0.54, 0.60), chlamydial infection (estimated Gini coefficient = 0.45; 95% CI = 0.40, 0.43), and herpes (estimated Gini coefficient=0.26; 95% CI=0.22, 0.29). CONCLUSIONS: Geographically targeted interventions may be most appropriate for syphilis and gonorrhea. For less-concentrated infections, control strategies must reach a wider portion of the population.

Privacy protection versus cluster detection in spatial epidemiology.

OBJECTIVES: Patient data that includes precise locations can reveal patients' identities, whereas data aggregated into administrative regions may preserve privacy and confidentiality. We investigated the effect of varying degrees of address precision (exact latitude and longitude vs the center points of zip code or census tracts) on detection of spatial clusters of cases. METHODS: We simulated disease outbreaks by adding supplementary spatially clustered emergency department visits to authentic hospital emergency department syndromic surveillance data. We identified clusters with a spatial scan statistic and evaluated detection rate and accuracy. RESULTS: More clusters were identified, and clusters were more accurately detected, when exact locations were used. That is, these clusters contained at least half of the simulated points and involved few additional emergency department visits. These results were especially apparent when the synthetic clustered points crossed administrative boundaries and fell into multiple zip code or census tracts. CONCLUSIONS: The spatial cluster detection algorithm performed better when addresses were analyzed as exact locations than when they were analyzed as center points of zip code or census tracts, particularly when the clustered points crossed administrative boundaries. Use of precise addresses offers improved performance, but this practice must be weighed against privacy concerns in the establishment of public health data exchange policies.

Transmission network analysis to complement routine tuberculosis contact investigations.

OBJECTIVE: We examined the feasibility and value of network analysis to complement routine tuberculosis (TB) contact investigation procedures during an outbreak. METHODS: We reviewed hospital, health department, and jail records and interviewed TB patients. Mycobacterium tuberculosis isolates were genotyped. We evaluated contacts of TB patients for latent TB infection (LTBI) and TB, and analyzed routine contact investigation data, including tuberculin skin test (TST) results. Outcomes included number of contacts identified, number of contacts evaluated, and their TST status. We used network analysis visualizations and metrics (reach, degree, betweenness) to characterize the outbreak. RESULTS: secondary TB patients and more than 1200 contacts. Genotyping detected a 21-band pattern of a strain W variant. No HIV-infected patients were diagnosed. Contacts prioritized by network analysis were more likely to have LTBI than nonprioritized contacts (odds ratio=7.8; 95% confidence interval=1.6, 36.6). Network visualizations and metrics highlighted patients central to sustaining the outbreak and helped prioritize contacts for evaluation. CONCLUSIONS: A network-informed approach to TB contact investigations provided a novel means to examine large quantities of data and helped focus TB control.
