The quality improvement experience in a high-performing local health department: Los Angeles County.

Quality improvement in public health is a key element in the movement toward accreditation. Multiple national, state, and local initiatives are under way to define quality in a public health context and to develop tools and promising practices to support quality-improvement efforts in local health departments. Until recently, efforts to improve quality at the local level have largely focused on performance measurement to assess the relationship between inputs, outputs, and outcomes. The Los Angeles County Department of Public Health has developed its own unique approach to quality improvement. This approach includes focusing on three overlapping areas (professional practice, performance improvement, and public health science) that align closely with essential public health services 8 (competent worker), 9 (evaluation), and 10 (research). Broadening the focus of quality-improvement efforts to include these three areas (rather than performance improvement alone) provides additional opportunities to address key infrastructure issues that may affect the quality of services that are provided to the public and, thus, health outcomes. While the experience in Los Angeles County parallels other efforts, it includes unique elements that will be of use to public health professionals in other agencies.

A public health nursing practice model: melding public health principles with the nursing process.

There has been a shift in emphasis in public health from the provision of personal health services for individuals to efforts targeted at improving the health of the whole community. Many in public health nursing (PHN) have welcomed this shift, recognizing the important role PHN can play in promoting health and preventing disease for all. There continues to be a need to redefine PHN roles and practice so that public health nurses can participate more effectively. Los Angeles County Department of Health Services Public Health Nursing (LAC PHN) has developed a practice model grounded in nationally recognized components: the public health team, PHN standards of practice, the 10 Essential Public Health Services, Healthy People 2010's 10 Leading Health Indicators and additional local indicators, and the Minnesota Public Health Nursing Interventions Model. The LAC PHN Practice Model provides a conceptual framework that assists in clarifying the role of the public health nurse and presents a guide for public health practice applicable to all public health disciplines.
