This comprehensive summary and set of study notes covers all essential material from Chapter 6: Public Health System Performance. This guide details how public health is evaluated, the initiatives used to improve the system, and the actual performance of the United States compared to its peers.
### I. Core Criteria for Evaluating Performance
Public health system performance is assessed based on three primary pillars:
* Effectiveness: Determines if the desired benefits of public health practices are actually being achieved.
* Efficiency: Compares the benefits achieved to the resources expended. It asks if alternate practices could achieve the same or greater benefits with fewer resources.
* Equity: Evaluates whether public health practices are effective in minimizing population health disparities.
Evidence-Based Public Health is defined as practice that has demonstrated effectiveness, efficiency, and equitability through scientific performance evaluation. This follows a direct parallel to evidence-based medicine.

### II. Components and Levels of Evaluation
Performance evaluation occurs at two levels: the individual program/policy level and the population level (using mortality and morbidity measures). Every evaluation—whether for a single program or the entire system—consists of three components:
1. Structure: The resources available, including organization, financing, target population characteristics, and the physical/social/economic environment.
2. Process: Refers to how the program, service, or policy was actually implemented.
3. Outcomes: The expected results. Program-specific outcomes are usually short-term, while changes in health impact are long-term goals.

### III. System Improvement: Accreditation and Credentialing
Accreditation and credentialing are viewed as process-improvement initiatives that focus on the quality of the workforce, policies, and data.
#### 1. Quality of the Workforce
* CEPH (Council on Education for Public Health): An independent agency that accredits schools and programs of public health. It evaluates curricula based on five core areas (Biostatistics, Environmental Health, Epidemiology, Health Policy/Management, Social/Behavioral Sciences) and seven cross-cutting areas (e.g., Communication, Diversity, Ethics, Systems Thinking).
* Core Competencies Project: Developed by the Council on Linkages, it identifies three tiers of skills (entry-level, management, and senior leadership) across eight skill domains.
* NBPHE (National Board of Public Health Examiners): Established in 2005 to ensure graduates have mastered contemporary public health knowledge. It administers the CPH (Certified in Public Health) exam.
#### 2. Quality of Organizations and Data
* PHAB (Public Health Accreditation Board): Accredits state and local health departments to advance quality and performance. Its program includes Domains (based on the 10 Essential Services), Standards (expected performance levels), and Measurements (metrics to assess standards).
* CDC: A primary agency involved in the continual development of high-quality data to assess performance.

### IV. Report Card Initiatives (Outcome Evaluations)
Report cards evaluate the outcomes of the public health system as a whole, specifically focusing on population health status, morbidity, and mortality.
* Healthy People: A national health-promotion agenda that sets objectives and monitors progress. Challenges include a constrained printed format, an unmanageable list of objectives, a lack of transparency in target-setting, and a lack of data to assess certain progress.
* America’s Health Rankings: Ranks states based on health outcomes and determinants using an ecological model.
* County Health Rankings & Roadmaps: A partnership between the Robert Wood Johnson Foundation and the University of Wisconsin. It ranks almost every U.S. county based on health factors (behaviors, clinical care, social/economic factors, and physical environment) and outcomes.

### V. Performance of the U.S. Public Health System
Using population-level outcomes, the U.S. system is evaluated against its peer countries, often showing poor results in effectiveness and equity.
* Life Expectancy: The U.S. ranked 10th out of 13 for male life expectancy at birth and 12th out of 13 for females.
* Age-Adjusted Mortality: In 2002, the rate for African Americans (13.4 per 1,000) was significantly higher than for White males (9.9 per 1,000), highlighting a lack of equity.
* Quality of Life (2002): The U.S. had the lowest-ranked HALE (Healthy Life Expectancy) for males among 13 countries and the highest (worst) DALY (Disability-Adjusted Life Years).
* Infant and Maternal Mortality: The U.S. Infant Mortality Rate (IMR) was the highest among 13 peer countries in 2004. IMR for African Americans (13.8) was more than double that of Whites (5.8). Maternal mortality was the 3rd highest among peers.

### VI. Key Sources for Evidence-Based Practices
Mastering these organizations is vital for full marks on "resources" questions:
* AHRQ: Electronic Preventive Services Selector.
* CDC: Guide to Community Preventive Services.
* The Cochrane Collaboration: Library of systematic reviews of healthcare interventions.
* NACCHO: Model Practices Database for local health agencies.
