Public Health Importance
• Important, measurable health outcomes
• Substantial cost savings
– Annual cost savings of ~1 billion
• Supports multiple public health goals

Reduction of racial disparities
Infectious disease control, including HIV prevention
Bio-terrorism preparedness
Reproductive health and infant health
Identifies opportunities to improve public health infrastructure
• Focus for critical collaboration between communities & health
departments
• Addresses unfinished history & broken trust

Why Chlamydia & Why Now?
• Most common communicable disease
reported disease in California
– Over 100,000 reported cases in 2001
– Over 75% of cases are seen in the private sector
• Significant health consequences
– Most common cause of preventable infertility
– Facilitates sexual transmission of HIV
• New technology = new opportunity
– Urine tests & single dose treatment = easier to reach,
treat & cure at-risk populations
• HEDIS increases private sector interest
– Potential public/private partnership
Chlamydia Action Coalition
A State-Wide Public/Private Partnership
funded by the
California HealthCare Foundation

Chlamydia Screening HEDIS
Measure
• The Measure: the percentage of Medicaid and commercially
enrolled women 15 through 25 who were identified as sexually
active, who were continuously enrolled during the reporting
year, and who have at least one test for chlamydia during the
reporting year.
Number tested
Number of sexually active *
* Denominator may exclude plan employees to protect confidentiality

Chlamydia HEDIS Data Warehouse
• Centralized Data Warehouse with Electronic
Transmission of Chlamydia Screening Data
– Collection of HEDIS numerator data
– Prevalence Monitoring
• Coordinate with ELR of communicable
diseases
HIPAA Basics
• What is HIPAA?
– Health Insurance Portability and Accountability
Act
– Provides the first national standards for protecting
the privacy of health information
– HIPAA Privacy Rule regulates how certain entities,
called covered entities, use and disclose certain
protected health information (PHI)
Who is Covered?
• Three types of covered entities
– health plans, (e.g., Medicaid, Medicare, and the
Veterans Health Administration)
– health-care clearinghouses, (billing service,
repricing company, or community health
information system)
– health-care providers who transmit health
information in electronic form in connection with
certain transactions (e.g., physicians, hospitals, and
clinics)
Impact on Public Health
• Public health uses PHI to identify, monitor,
and respond to disease, death, and disability
among populations
• Privacy Rule expressly permits PHI to be
shared by covered entities for specified public
health purposes
• Public health authority may also be a covered
entity in some cases
Permitted PHI Disclosures Without
Authorization
• Where required by law
• PHI can be disclosed to public health authorities and
their authorized agents for public health purposes
• Health research
• Abuse, neglect, or domestic violence
• Law enforcement
• Judicial and administrative proceedings.
• Cadaveric organ, eye, or tissue donation purposes
• For oversight activities authorized by law
• Worker's compensation
Included Public Health Activities
• reporting of disease or injury
• reporting vital events (e.g., births or deaths)
• conducting public health surveillance,
investigations, or interventions
• reporting child abuse and neglect
• monitoring adverse outcomes related to food
(including dietary supplements), drugs,
biological products, and medical devices
Requirements for Covered Entities
• Accounting for Public Health Disclosures
– Covered entity must be able to provide a patient an
accounting of disclosure even for disclosures permitted or
required by law
• Notice of Privacy Practices
– individuals have the right to adequate notice of the uses and
disclosures of PHI that may be made by the covered entity,
as well as their rights and the covered entity's legal
obligations
• Minimum Necessary Standard
– directs covered entities to limit the amount of information
disclosed to the minimum necessary to achieve the
specified goal
Rapid HIV Testing
A key strategy of the Advancing HIV
Prevention Initiative is to use rapid HIV tests to
expand HIV testing outside clinical settings.
