Preventive Healthcare Services

2.3K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

Sexually Transmitted Infections

2.0K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

43.0K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Summary

San Francisco developed a framework to measure the impact of HIV partner services (PS). This HIV testing strategy successfully identified newly diagnosed HIV cases, improving public health outcomes.

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Disease Control

Background:

  • The San Francisco Department of Public Health (SFDPH) aims to provide HIV partner services (PS) to all new HIV diagnoses.
  • Measuring the impact of HIV PS is challenging, necessitating a robust evaluation framework.

Purpose of the Study:

  • To develop and implement a framework for expanding and monitoring HIV partner services (PS) in San Francisco.
  • To establish process and outcome measures for evaluating the effectiveness of HIV PS.

Main Methods:

  • Developed process and outcome measures for HIV PS evaluation.
  • Utilized an electronic surveillance and case-management system for data recording.
  • Examined HIV PS data from 2005-2011.

Main Results:

  • In 2011, 69.7% of eligible patients were interviewed, naming 109 partners.
  • Of named partners, 31.2% were already diagnosed with HIV.
  • HIV testing among partners not known to be HIV-infected yielded a 22.6% positivity rate.
  • The proportion of HIV newly diagnosed through the PS program increased from 15.4% (2005) to 69.5% (2011).

Conclusions:

  • Locally relevant outcome measures are crucial for expanding HIV PS.
  • HIV PS effectively functions as a targeted screening activity, identifying new HIV cases.
