Rationale
This measure assesses appropriate screening for chlamydia among women in a specific age demographic. Chlamydia is one of the most frequently occurring sexually-transmitted diseases in the United States, resulting in over 2.8 million new cases each year. Women 14–30 are particularly susceptible and account for over 80% of new cases, according to the U.S. National Health and Nutrition Examination Survey. Additionally, heath care costs attributable to chlamydia and its complications exceed $3.5 billion per year in the U.S.. Early detection and treatment have proven to be effective in preventing and managing chlamydia. Several studies have shown that screening reduces overall disease prevalence by 4.2% and is strongly correlated with a reduced incidence of pelvic inflammatory disease (PID). This measure facilitates efforts toward early screening and treatment to improve health outcomes for infected women and prevent the spread of disease.
Clinical Recommendation Statement
The U.S. Preventive Services Task Force (USPSTF) strongly recommends that clinicians routinely screen all sexually active women aged 25 years and younger, and other asymptomatic women at increased risk for infection, for chlamydial infection.  Rating: A recommendation (http://www.ahrq.gov/clinic/uspstf/uspschlm.htm). 

The American Academy of Family Physicians (AAFP, 2005) strongly recommends screening all sexually active females age 25 years or younger and other women at increased risk for chlamydia.

American College of Preventive Medicine:  Sexually active women with risk factors should be screened annually by any well-validated, laboratory-based amplification or antigen method, using cervical or urine specimens. Risk factors include age <=25 years, a new male sex partner or two or more partners during the preceding year, inconsistent use of barrier contraception, history of a prior sexually transmitted disease (STD), African-American race, and cervical ectopy. All partners of women with positive tests should be tested for Chlamydia trachomatis. Women with mucopurulent discharge, suggestive of cervicitis, should be tested immediately.

The American College of Obstetricians and Gynecologists recommends routine screening for chlamydial infection for all sexually active adolescents and other asymptomatic women at high risk for infection.

Definition
Initial Patient Population(s): All female patients ages 16 to 24 years of age during the measurement period
Definition
Denominator(s): Patients in the initial population with an encounter during measurement period.  This measure is stratified into three age groups: 

Population 1: All female patients 16-24 years of age during the measurement period who were identified as sexually active

Population 2: All female patients 16-20 years of age during the measurement period who were identified as sexually active. 

Population 3: All female patients 21-24 years of age during the measurement period who were identified as sexually active
Definition
Denominator Exclusion(s): Female patients who received a pregnancy test solely as a safety precaution before ordering x-ray or specified medications
Definition
Numerator(s): The number of female patients screened at least once for Chlamydia during the measurement period
Definition
Denominator Exception(s): N/A
