Providing affordable family housing and reducing residential segregation by income. A systematic review.

The inadequate supply of affordable housing for low-income families and the increasing spatial segregation of some households by income, race, ethnicity, or social class into unsafe neighborhoods are among the most prevalent community health concerns related to family housing. When affordable housing is not available to low-income households, family resources needed for food, medical or dental care, and other necessities are diverted to housing costs. Two housing programs intended to provide affordable housing and, concurrently, reduce the residential segregation of low-income families into unsafe neighborhoods of concentrated poverty, are reviewed: the creation of mixed-income housing developments and the Department of Housing and Urban Development (HUD) Section 8 Rental Voucher Program. The effectiveness of mixed-income housing developments could not be ascertained by this systematic review because of a lack of comparative research. Scientific evidence was sufficient to conclude that rental voucher programs improve household safety as measured by reduced exposure to crimes against person and property and decreased neighborhood social disorder. Effectiveness of rental voucher programs on youth health risk behaviors, mental health status, and physical health status could not be determined because too few studies of adequate design and execution reported these outcomes.

Culturally competent healthcare systems. A systematic review.

Culturally competent healthcare systems-those that provide culturally and linguistically appropriate services-have the potential to reduce racial and ethnic health disparities. When clients do not understand what their healthcare providers are telling them, and providers either do not speak the client's language or are insensitive to cultural differences, the quality of health care can be compromised. We reviewed five interventions to improve cultural competence in healthcare systems-programs to recruit and retain staff members who reflect the cultural diversity of the community served, use of interpreter services or bilingual providers for clients with limited English proficiency, cultural competency training for healthcare providers, use of linguistically and culturally appropriate health education materials, and culturally specific healthcare settings. We could not determine the effectiveness of any of these interventions, because there were either too few comparative studies, or studies did not examine the outcome measures evaluated in this review: client satisfaction with care, improvements in health status, and inappropriate racial or ethnic differences in use of health services or in received and recommended treatment.

Developing quality indicators for local health departments: experience in Los Angeles County.

OBJECTIVES: To develop public health quality indicators for local health department (LHD) use. METHODS: An indicator development team utilized public health quality measurement concepts, reviewed existing quality measurement-related initiatives, and conducted interviews with LHD staff in order to identify and develop quality indicators for the Los Angeles County Health Department. RESULTS: Sixty-one recommended and 50 acceptable (i.e., scientifically sound but less useful) indicators were developed, with an emphasis on measuring process quality in services delivery. Pre-existing indicators from external sources, when available, were often not well suited to the Health Department's needs. The indicator development process clarified conceptual issues, highlighted strengths and limitations of potential indicators, and revealed implementation barriers. CONCLUSIONS: A limited number of generally available, quantitative indicators of local public health quality exist. Indicators addressing the delivery of LHD services can be locally developed to fill an important gap in public health quality-improvement efforts. However, implementation of quality measurement is difficult due to limited evidence on public health practices, sparse data resources, unclear accountability, and inconsistent organizational motivation.

Prevalence of childhood asthma and associated morbidity in Los Angeles County: impacts of race/ethnicity and income.

Racial/ethnic and socioeconomic disparities in the prevalence of childhood asthma have been reported nationally but few population-based studies in local and regional settings have been reported. To assess variation in the prevalence of childhood asthma and associated morbidity across race/ethnic and income groups in the Los Angeles County population, we analyzed data on a random sample of 6004 children (< or = 17 years old) enrolled in a countywide health survey from September 1999 through April 2000. The prevalence of childhood asthma was highest in blacks (15.8%), intermediate in whites (7.3%) and Asians (6.0%), and lowest in Latinos (3.9%; p < 0.001). These differences persisted after controlling for income, measures of health care access, and other covariates. Asthma prevalence was inversely related to income in all racial/ethnic groups except Latinos from Spanish-speaking households. Among children with asthma, blacks and Latinos were more likely than whites to report asthma-related limitations in physical activity and need for urgent medical services. These findings indicate marked disparities in asthma prevalence and related morbidity in this large urban child population and highlight the importance of efforts to identify high-risk subpopulations for focused prevention and treatment interventions.

Community interventions to promote healthy social environments: early childhood development and family housing. A report on recommendations of the Task Force on Community Preventive Services.

The sociocultural environment exerts a fundamental influence on health. Interventions to improve education, housing, employment, and access to health care contribute to healthy and safe environments and improved community health. The Task Force on Community Preventive Services (the Task Force) has conducted systematic reviews of early childhood development interventions and family housing interventions. The topics selected provide a unique, albeit small, beginning of the review of evidence that interventions do effectively address sociocultural factors that influence health. Based on these reviews, the Task Force strongly recommends publicly funded, center-based, comprehensive early childhood development programs for low-income children aged 3-5 years. The basis for the recommendation is evidence of effectiveness in preventing developmental delay, assessed by improvements in grade retention and placement in special education. The Task Force also recommends housing subsidy programs for low-income families, which provide rental vouchers for use in the private housing market and allow families choice in residential location. This recommendation is based on outcomes of improved neighborhood safety and families' reduced exposure to violence. The Task Force concludes that insufficient evidence is available on which to base a recommendation for or against creation of mixed-income housing developments that provide safe and affordable housing in neighborhoods with adequate goods and services. This report provides additional information regarding these recommendations, briefly describes how the reviews were conducted, and discusses implications for applying the interventions locally.

Los Angeles County drug court programs: initial results.

Los Angeles County established its first drug court program in 1994 in response to escalating criminal activity associated with substance abuse and overcrowded jails. This paper describes results of an evaluation of 803 drug court participants admitted to the program between 1994 and 1997. Of all drug court participants, 76% remained free of any new arrests throughout the one-year followup period, compared to 63% of participants in a drug diversion education program and 49% of the felony defendants not exposed to either program. Of offenders completing the drug court program 80% had no arrests, compared to 67% for non-completers. Drug related re-arrests were significantly lower among drug court graduates (13%) than offenders with no program participation (30%). The study results suggest that drug court participation and graduation decrease the likelihood of repeated arrests, including drug-related arrests. Drug courts represent a promising collaboration between criminal justice and public health agencies.

Developing a public health Web site: the Los Angeles County experience.

The use of the Internet in public health practice is becoming increasingly widespread. The Internet is an important tool for supporting the mission and core functions of local health departments. However, most local health departments have limited resources and technical capacity to develop, deploy, and encourage use of large and complex Web sites. In Los Angeles County, the local health department was able to build and expand public health information systems on the Internet with a limited investment of financial and technical resources. The development process, key functions, and key factors in the success of this effort are described.

Heterogeneity of health disparities among African American, Hispanic, and Asian American women: unrecognized influences of sexual orientation.

OBJECTIVES: This study compared health indicators among self-identified lesbians/bisexual women and heterosexual women residing in Los Angeles County. METHODS: Respondents were English-speaking Hispanic, African American, and Asian American women. Health status, behavioral risks, access barriers, and indicators of health care were assessed. RESULTS: Prevalence rates of chronic health conditions were similar among women in the 3 racial/ethnic groups. However, lesbians and bisexual women evidenced higher behavioral risks and lower rates of preventive care than heterosexual women. CONCLUSIONS: Among racial/ethnic minority women, minority sexual orientation is associated with increased health risks. The effects of sexual minority status need to be considered in addressing health disparities affecting this population.

How do we translate science into public health policy and law?

Scientific knowledge concerning effective preventive measures to preserve and protect the health of the public continues to grow exponentially. Methods for assessing the impact of population-based interventions such as policies and laws have also greatly increased in the past decade, including systematic approaches that allow general findings to be drawn from various studies, especially those developed as part of the Guide to Community Preventive Services (Community Guide). However, the translation of the collected scientific evidence gathered to date has been spotty and problematic. Success stories do exist, including community water fluoridation, a significant factor in improvements in reduction of tooth decay over the past 50 years. Even for interventions with a strong science base, such as community water fluoridation, significant barriers to implementation of effective strategies discovered through research remain. Barriers include public misunderstanding of health issues and proposed solutions such as fluoridation; lack of engagement on the part of the media in communicating known effective strategies; and reluctance on the part of policymakers to champion approaches that concern but may not be advocated by their constituencies. The increasing burden of chronic disease places public policymakers into non-traditional roles, such as advocating behavior change as a preventive measure. Science is a critical tool to help legislators and policymakers "connect the dots" between public policies. For example, the elimination or degrading of physical education programs in schools is an important factor in addressing the national epidemic of childhood overweight and obesity in addition to the increase in rates of Type II diabetes among children. This article provides an overview of the past, present, and future associated with translating science into public health policy and law, including a review of tools and strategies to address existing and expanding public health challenges. The article also provides and discusses examples of translating and implementing science-based solutions to address public health problems effectively.

Public health quality measurement: concepts and challenges.

Public health agencies increasingly are recognizing the need to formally and quantitatively assess and improve the quality of their programs, information, and policies. Measuring quality can help organizations monitor their progress toward public health goals and become more accountable to both the populations they serve and policy makers. Yet quality assessment is a complex task that involves precise determination and specification of useful measures. We discuss a well-established conceptual framework for organizing quality assessment in the context of planning and delivery of programs and services by local health departments, and consider the strengths and limitations of this approach for guiding quality improvement. We review several past and present quality measurement-related initiatives designed for public health department use, and discuss current and future challenges in this evolving area of public health practice.

Standardized emergency management system and response to a smallpox emergency.

The smallpox virus is a high-priority, Category-A agent that poses a global, terrorism security risk because it: (1) easily can be disseminated and transmitted from person to person; (2) results in high mortality rates and has the potential for a major public health impact; (3) might cause public panic and social disruption; and (4) requires special action for public health preparedness. In recognition of this risk, the Los Angeles County Department of Health Services (LAC-DHS) developed the Smallpox Preparedness, Response, and Recovery Plan for LAC to prepare for the possibility of an outbreak of smallpox. A unique feature of the LAC-DHS plan is its explicit use of the Standardized Emergency Management System (SEMS) framework for detailing the functions needed to respond to a smallpox emergency. The SEMS includes the Incident Command System (ICS) structure (management, operations, planning/intelligence, logistics, and finance/administration), the mutual-aid system, and the multi/interagency coordination required during a smallpox emergency. Management for incident command includes setting objectives and priorities, information (risk communications), safety, and liaison. Operations includes control and containment of a smallpox outbreak including ring vaccination, mass vaccination, adverse events monitoring and assessment, management of confirmed and suspected smallpox cases, contact tracing, active surveillance teams and enhanced hospital-based surveillance, and decontamination. Planning/intelligence functions include developing the incident action plan, epidemiological investigation and analysis of smallpox cases, and epidemiological assessment of the vaccination coverage status of populations at risk. Logistics functions include receiving, handling, inventorying, and distributing smallpox vaccine and vaccination clinic supplies; personnel; transportation; communications; and health care of personnel. Finally, finance/administration functions include monitoring costs related to the smallpox emergency, procurement, and administrative aspects that are not handled by other functional divisions of incident command systems. The plan was developed and is under frequent review by the LAC-DHS Smallpox Planning Working Group, and is reviewed periodically by the LAC Bioterrorism Advisory Committee, and draws upon the Smallpox Response Plan and Guidelines of the Centers for Disease Control and Prevention (CDC) and recommendations of the Advisory Committee on Immunization Practices (ACIP). The Smallpox Preparedness, Response, and Recovery Plan, with its SEMS framework and ICS structure, now is serving as a model for the development of LAC-DHS plans for responses to other terrorist or natural-outbreak responses.

Assessing the burden of disease and injury in Los Angeles County using disability-adjusted life years.

OBJECTIVE: This study was designed to assess the burden of disease and injury in the Los Angeles County population using Disability-Adjusted Life Years (DALYs), a composite measure of premature mortality and disability that equates to years of healthy life lost. METHODS: DALYs, stratified by gender and race/ethnicity, were calculated for 105 health conditions and aggregated groups of conditions for the Los Angeles County population for 1997. Years of Life Lost (YLLs) were calculated using 1997 county mortality statistics and published life tables. Years Lived with Disability (YLDs) were derived from age- and gender-specific disease incidence and disability data from the Global Burden of Disease Study. RESULTS: DALYs produced a substantially different ranking of disease and injury burden than did mortality rates alone. The leading five causes of DALYs for males in the county were ischemic heart disease, violence, alcohol dependence, drug overdose and other intoxications, and depression. For females, the leading five causes were ischemic heart disease, alcohol dependence, diabetes, depression, and osteoarthritis. Differences in the rank order were also observed by race/ethnicity. The age-adjusted rate of DALYs for all health conditions combined was highest in African Americans (190 per 1,000), followed by American Indians (149 per 1,000), whites (113 per 1,000), Latinos (94 per 1,000), and Asians/Pacific Islanders (77 per 1,000). CONCLUSIONS: The DALYs measure is a promising new tool to improve the capacity of local health departments and other health agencies to assess population health and establish an evidence base for public health decisions.

Reinvigorating public health core functions: restructuring Los Angeles county's public health system.

In 1997, the Los Angeles County Department of Health Services launched an effort to revitalize its Public Health Services division. County investments resulted in the creation of 241 new positions, facilitating the establishment of new offices addressing neglected chronic disease prevention, staff development, training, and communication. Service effectiveness and community responsiveness were enhanced by decentralizing leadership through eight Area Health Offices and strengthening partnerships with private health care providers, community-based organizations, and managed care organizations. Infrastructure enhancements included the development of program performance measures, countywide health indicators, a central health assessment and epidemiology office, and a new countywide biennial survey.

Public health and business: a partnership that makes cents.

Historically, public health agencies have had relatively few formal partnerships with private business. However, both groups share an interest in ensuring a healthy population. Businesses have a financial interest in supporting organized public health efforts; in turn, business partnerships can increase the reach and effectiveness of public health. This paper makes the case for the business sector's participation in the broad public health system and its support of governmental public health agencies. Examples of past and current partnerships exemplify how public health efforts benefit business and suggest opportunities for future collaboration to improve the public's health.

Promoting evidence-based public health policy: can we have better evidence and more action?

Evidence-based approaches (those explicitly linked to the best available scientific evidence and reflecting community preferences and feasibility) are increasingly used to inform health policy decision making on the burden of a disease attributable to particular causes, interventions and policies that might work to confront those causes, and issues of community fit and feasibility. This paper introduces several tools for evidence-based public health: the health impact assessment, the systematic review, and a portfolio for assuring community fit and feasibility. Discussion of these tools serves as a springboard to consider how to better bring scientific evidence to bear on real-life health issues.
