RESUMEN
OBJECTIVE: To test the hypothesis that our motivational sexual health intervention (SexHealth) would increase health service uptake when compared with control. STUDY DESIGN: In a randomized controlled trial at a pediatric emergency department, sexually active adolescents received either the SexHealth intervention or printed materials (control). SexHealth, delivered by a health educator, was a tablet-based, interactive intervention that included motivational techniques to promote sexual health, condom skills training, and tailored service recommendations. We assessed feasibility (eg, intervention completion, recommendations discussed, intervention duration), acceptability (ie, proportion enrolled and rating intervention as satisfactory), and efficacy; secondary outcomes were sexual and care-seeking behaviors at 6 months. The efficacy outcome was completion of ≥1 service at the index visit (ie, counseling, condoms, emergency contraception for immediate or future use, pregnancy/sexually transmitted infection/HIV testing, sexually transmitted infection treatment, and clinic referral). RESULTS: We enrolled 91 participants (intervention = 44; control = 47). The intervention demonstrated high feasibility: 98% completed the intervention; 98% of recommendations were discussed; duration was 24.6 minutes, and acceptability: 87% of eligible adolescents enrolled and 93% rated the intervention as fairly to very satisfactory. Compared with controls, intervention participants were more likely to complete ≥1 service (98% vs 70%, P < .001) including HIV testing (33% vs 6%, P = .02) and emergency contraception (80% vs 0%, P = .01). There were no meaningful differences between arms in behaviors at follow-up. CONCLUSIONS: SexHealth was feasible to implement, acceptable to youth, and resulted in increased uptake of health services during the emergency department visit. Additional strategies may be needed to extend intervention effects over time. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov; NCT03341975.

We report on data we collected from a 2018 survey examining jails' human papillomavirus virus vaccine delivery capacity and on a secondary analysis we conducted to describe factors similarly associated with delivery planning for the COVID-19 vaccine. We provide recommendations for delivering the COVID-19 vaccine in jails, based on evidence from Kansas, Iowa, Nebraska, and Missouri. Our key finding is that jails have limited staff to implement vaccination and will require collaboration between jail administrators, jail medical staff, and local health departments.

Wearing masks is a CDC-recommended* approach to reduce the spread of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), by reducing the spread of respiratory droplets into the air when a person coughs, sneezes, or talks and by reducing the inhalation of these droplets by the wearer. On July 2, 2020, the governor of Kansas issued an executive order (state mandate), effective July 3, requiring masks or other face coverings in public spaces. CDC and the Kansas Department of Health and Environment analyzed trends in county-level COVID-19 incidence before (June 1-July 2) and after (July 3-August 23) the governor's executive order among counties that ultimately had a mask mandate in place and those that did not. As of August 11, 24 of Kansas's 105 counties did not opt out of the state mandate§ or adopted their own mask mandate shortly before or after the state mandate was issued; 81 counties opted out of the state mandate, as permitted by state law, and did not adopt their own mask mandate. After the governor's executive order, COVID-19 incidence (calculated as the 7-day rolling average number of new daily cases per 100,000 population) decreased (mean decrease of 0.08 cases per 100,000 per day; net decrease of 6%) among counties with a mask mandate (mandated counties) but continued to increase (mean increase of 0.11 cases per 100,000 per day; net increase of 100%) among counties without a mask mandate (nonmandated counties). The decrease in cases among mandated counties and the continued increase in cases in nonmandated counties adds to the evidence supporting the importance of wearing masks and implementing policies requiring their use to mitigate the spread of SARS-CoV-2 (1-6). Community-level mitigation strategies emphasizing wearing masks, maintaining physical distance, staying at home when ill, and enhancing hygiene practices can help reduce transmission of SARS-CoV-2.

Given incarcerated women's frequent transitions between jail and community, it is important to seize opportunities to provide comprehensive health care. A potential time to provide care might be when getting tested for sexually transmitted infections (STIs). Our objective was to determine the proportion of women receiving STI testing and correlates, following jail release. This secondary analysis was of one-year follow-up data from women who participated in a jail-based cervical health literacy intervention in three Kansas City jails from 2014 to 2016. Most (82%) completed the survey in the community. The analysis included 133 women. Mean age 35 years (19-58 years). Sixty-two percent obtained STI testing within one-year post-intervention. Using logistic regression this was associated with younger age (odds ratio [OR] = 0.87; 95% confidence interval [CI] 0.80, 0.95), receiving high school education (OR = 4.33; 95% CI 1.00, 18.74), having insurance (OR = 4.32; 95% CI 1.25, 14.89), no illicit drug use (OR = 0.09; 95% CI 0.01, 0.81), and no drinking problem (OR = 0.04; 95% CI 0.00, 0.45). In this study, many women sought STI testing following jail release. Clinicians/public health practitioners may find it useful to engage these high-risk women in broader women's health services seeking STI testing.

CONTEXT: Local health departments (LHDs) play a vital role in community vaccination programs for human papillomavirus (HPV) infection, but little research has been done to assess LHD interest in cross-sectoral partnerships to vaccinate high-risk groups, specifically incarcerated persons. OBJECTIVE: To describe factors associated with interest in a novel implementation strategy linking LHDs with jails in 4 Midwestern states to deliver HPV vaccine. DESIGN: Survey based on the Consolidated Framework for Implementation Research (CFIR) model given to LHD administrators. A modified Poisson relative risk regression was used to assess the relationship between independent variables and LHD interest in implementation of a jail-based HPV vaccination program. SETTING: LHDs in Kansas, Missouri, Iowa, and Nebraska. PARTICIPANTS: From September 2017 to April 2018, two-thirds (237/344) of invited LHD administrators from the 4 states responded to the survey. MAIN OUTCOME MEASURE: LHD interest in implementation of a jail-based HPV vaccination program. RESULTS: Forty-five percent of LHDs were interested in learning more about implementing a jail-based HPV vaccination program, and 2% already offered or had plans to offer HPV vaccine in their jails. Barriers to implementation were cost (66%), inmates' short incarcerations (47%), and availability of medical staffing (43%). LHD characteristics associated with interest in implementation of a jail-based HPV vaccination program included "inner setting" CFIR variables, which capture the structural and cultural context for program implementation: 7 or more employees (odds ratio [OR] = 2.22; 95% confidence interval [CI], 1.24-3.95), perception of importance to provide HPV vaccine in jails (OR = 3.70; 95% CI, 2.00-6.84), and already providing any vaccines in jails (OR = 2.62; 95% CI, 1.18-5.80). CONCLUSIONS: Nearly half of LHDs in the region expressed interest in partnering with local entities to meet HPV vaccination needs of high-risk groups. Research on cross-sectoral partnerships and what these collaborations look like in practice is needed for public health impact.

School nurses are often sources of health-care support for teens with sexually transmitted infections (STIs) and unintended pregnancies. However, providing prevention (e.g., condoms) and teaching technical skills (e.g., condom use) needed to reduce high-risk sexual behavior may require a change in perceptions and policies. This study used a cross-sectional study design to assess nurses' perceptions of condom availability accompanied by sex education programs among high school nurses (n = 87) in Kansas. Results showed that school nurses in this study supported condom availability, were comfortable providing condoms, and felt condom availability was within the scope of their job but were less likely to provide condoms because of external barriers. Common barriers include administration, parents, cost, community support, and policies. School nurses, by virtue of their access to the majority of Kansas' adolescents, have the potential to provide sex education and tools such as condoms, so young people can prevent STIs and unintended pregnancies.

OBJECTIVES: To assess human papillomavirus (HPV) knowledge and vaccine awareness, intention, and uptake among adult inmates in Kansas jails. METHODS: We administered a survey with questions adapted from the US National Cancer Institute's Health Information National Trends Survey to 571 adult inmates in 3 Kansas jails from October 10 to 12, 2016, and January 25 to 27, 2017, to assess HPV knowledge and vaccine awareness, intention, and uptake. RESULTS: Although most adults across demographic groups recognized HPV as causing cervical cancer, knowledge was lower about other HPV-related cancers. Vaccine awareness was higher for women (70%) than men (41%). Only 8% of age-eligible men reported ever receiving the vaccine. Most adults across demographic groups reported "definitely" wanting to get the vaccine if offered in jail at no cost. CONCLUSIONS: Low uptake of HPV vaccine and high interest in receiving the vaccine in jails may indicate that vaccination availability for jail populations needs to be reexamined. Public Health Implications. Expanding HPV vaccine programs or partnerships to facilitate vaccine provision in jails could increase inmates' knowledge of and intention to receive vital health services.

An estimated 2.9 million new chlamydia infections occur in the United States each year. Among women, chlamydia can lead to serious adverse outcomes, including pelvic inflammatory disease and infertility. Chlamydia prevalence is highest among females aged 15-19 years. Despite long-standing recommendations directed at young, sexually active females, screening remains sub-optimal. Juvenile detention centers (JDCs) are uniquely situated to screen and treat high-risk adolescents. From 2009-2011, performance measure data on chlamydia screening coverage (proportion of eligible females screened) and positivity (proportion of females tested who were positive) were available from 126 geographically-dispersed JDCs in the United States. These facilities reported screening 55.2% of females entering the facilities (149,923), with a facility-specific median of 66.4% (range: 0-100%). Almost half (44.4%) of facilities had screening coverage levels of 75-100%. This screening resulted in the detection of 12,305 chlamydial infections, for an overall positivity of 14.7% (facility-specific median = 14.9%, range: 0-36.9%). In linear regression analysis, chlamydia positivity was inversely associated with screening coverage: as coverage increased, positivity decreased. The burden of chlamydia in JDCs is substantial; facilities should continue to deliver recommended chlamydia screening and treatment to females and identify mechanisms to increase coverage.

OBJECTIVE: Chlamydia re-infection data are used to inform and evaluate chlamydia control programmes. We quantitatively investigated the effect of denominator selection on estimating re-infection rates and trends. METHODS: Using data on women aged 15-44 years enrolled in Group Health Cooperative (GH), a Pacific Northwest health plan, annual chlamydia re-infection rates from 1998 to 2006 were calculated. Three different denominators were compared using person-years contributed by: (1) all women; (2) women with a prior documented chlamydial infection regardless of whether they were retested; and (3) women with a prior chlamydial infection who were retested within 14 months. RESULTS: From 1998 to 2006, among all women 15-44 years enrolled in GH, re-infection rates increased from 64 to 149 cases per 100 000 person-years. Among women with a prior infection, rates decreased from 10 857 to 8782 cases per 100 000 person-years. Among women with a prior infection who were retested, rates increased from 29 374 to 42 475 cases per 100 000 person-years. CONCLUSIONS: Using the same dataset, we demonstrate that it is possible to tell three different stories about the magnitude of rates and trends in chlamydia re-infection among women by using different denominators. All of these strategies have limitations, but restricting the denominator to women with a prior infection who are retested may best represent the population at-risk for re-infection. Still, rates do not account for additional factors influencing the number of re-infections diagnosed, including screening coverage and changes in test technology. Caution is needed in examining and comparing re-infection data.

BACKGROUND: Most sexually active people will be infected with a sexually transmitted infection (STI) at some point in their lives. The number of STIs in the United States was previously estimated in 2000. We updated previous estimates to reflect the number of STIs for calendar year 2008. METHODS: We reviewed available data and literature and conservatively estimated incident and prevalent infections nationally for 8 common STIs: chlamydia, gonorrhea, syphilis, herpes, human papillomavirus, hepatitis B, HIV, and trichomoniasis. Where available, data from nationally representative surveys such as the National Health and Nutrition Examination Survey were used to provide national estimates of STI prevalence or incidence. The strength of each estimate was rated good, fair, or poor, according to the quality of the evidence. RESULTS: In 2008, there were an estimated 110 million prevalent STIs among women and men in the United States. Of these, more than 20% of infections (22.1 million) were among women and men aged 15 to 24 years. Approximately 19.7 million incident infections occurred in the United States in 2008; nearly 50% (9.8 million) were acquired by young women and men aged 15 to 24 years. Human papillomavirus infections, many of which are asymptomatic and do not cause disease, accounted for most of both prevalent and incident infections. CONCLUSIONS: Sexually transmitted infections are common in the United States, with a disproportionate burden among young adolescents and adults. Public health efforts to address STIs should focus on prevention among at-risk populations to reduce the number and impact of STIs.

Young persons entering US jails and youth detention facilities have high rates of sexually transmitted diseases (STDs). The Centers for Disease Control and Prevention added STD screening guidelines specific to correctional settings to the 2010 STD Treatment Guidelines. This article summarizes published evidence from 1990 to 2009 used to develop the recommendations. The literature supports routine screening of adolescents and young women (aged ≤35 years, or on the basis of local institutional prevalence data) for chlamydia and gonorrhea because of high prevalence and the subsequent risk of adverse reproductive outcomes. Chlamydia positivity among young women (aged <20 years) in juvenile detention facilities and adult facilities is more than 14%. Men in correctional settings are also at high risk for chlamydia and gonorrhea. Among boys in juvenile detention facilities, chlamydia positivity is estimated at 6.6%; among young men in adult facilities, positivity is 16.6%. Screening men (to reduce sequelae among women) should be considered based on local epidemiology and resource availability. Syphilis screening is not strongly supported in published literature because of low prevalence and is not routinely recommended; however, some screening may be warranted based on local prevalence. Although there is a great diversity in the organization of correctional facilities, implementation of screening recommendations is possible owing to improvements in test technology (urine specimens) and through integration of a standard screening protocol. Based on the high burden of disease and substantial opportunities to reach a high-risk population, correctional facilities are important venues to target efforts to control STDs.

BACKGROUND: National notifiable disease data indicate that there were 99 cases of gonorrhea for every 100,000 persons in the United States in 2009, the lowest recorded gonorrhea rate in US history. However, the extent to which declining case reports signify a reduction in prevalence is unknown. METHODS: Gonorrhea prevalence was estimated among 16- to 24-year-old men and women entering the National Job Training Program (NJTP) between 2004 and 2009. Multivariate logistic regression was used to assess the probability of testing positive for gonorrhea over time. RESULTS: A total of 95,184 men and 91,697 women were screened for gonorrhea upon entry to the NJTP between 2004 and 2009. For women, gonorrhea prevalence increased from 2004 (2.6%) to 2006 (2.9%), then decreased steadily through 2009 (1.8%). For men, prevalence increased from 2004 (1.3%) to 2005 (1.6%), then decreased through 2009 (0.9%). Gonorrhea prevalence among black women decreased from 3.6% in 2004 to 2.5% in 2009 and was 2 to 4 times higher than prevalence among white women. Likewise, prevalence among black men decreased from 2.0% to 1.5% and was 8 to 22 times higher than prevalence among white men. After adjusting for gonorrhea risk factors, the odds of women and men testing positive for gonorrhea decreased by 50% and 40%, respectively, from 2004 to 2009. CONCLUSIONS: Declining trends in gonorrhea infection among NJTP entrants are similar to those observed in gonorrhea case report data, suggesting that the decrease in case reports is due to a decrease in prevalence. However, targeted interventions are needed to reduce gonorrhea infections in populations with disproportionate risk.

OBJECTIVES: Model impact of increasing screening and partner notification (PN) on chlamydia positivity. METHODS: We used a stochastic simulation model describing pair formation and dissolution in an age-structured heterosexual population. The model accounts for steady, casual, and concurrent partnerships and a highly sexually active core group. The model used existing sexual behavior data from the United States and was validated using chlamydia positivity data from Region X (Alaska, Idaho, Oregon, Washington). A screening program with a coverage rate of 20% was implemented among women aged 15 to 24 years. After 10 years, we increased screening coverage to 35%, 50%, and 65% and partner treatment rates from 20% to 40% and 55%. Finally, we included male screening (aged 15-24, screening coverage: 20% and 35%, partner treatment: 25% and 40%). We analyzed the effects on chlamydia positivity in women and the frequency of reinfection 6 months after treatment. RESULTS: The model described the decline in positivity observed from 1988 to 1997 in Region X, given screening coverage of 20% and a 25% partner treatment rate. Increasing screening coverage from 35% to 65% resulted in incremental decreases in positivity as did increasing the PN rate; a 23% reduction in positivity was achieved by either increasing screening by 3-fold or PN by 2-fold. Adding male screening to the program had less impact than increasing screening coverage or PN among women. Increased PN and treatment reduced reinfection rates considerably. CONCLUSIONS: Increasing efforts in PN may contribute at least as much to control of chlamydia infection as increasing screening coverage rates.

BACKGROUND: Given recent increasing case rates of Chlamydia trachomatis infection, we evaluated trends in chlamydia rates and related health outcomes in women and men aged 15 to 44 years who were enrolled in a Pacific Northwest health plan. METHODS: We identified chlamydia, pelvic inflammatory disease (PID), ectopic pregnancy, and male urethritis cases occurring annually during 1997-2007 using computerized health plan databases, calculating rates per 100,000 person-years (py) by gender and 5-year age groups. We also calculated annual chlamydia testing rates. RESULTS: In women, chlamydia testing rates increased by approximately 23% (220 tests per 1000 py in 1997 to 270 tests per 1000 in 2007). Chlamydia diagnosis rates rose from 449 cases/100,000 py in 1997 to 806/100,000 in 2007, a 79% increase (P = 0.01). Increases were greatest during 2005-2007, also the period of major conversion to nucleic acid amplification test. PID rates in this interval declined steadily from 823 cases/100,000 py to 473/100,000 (P < 0.01). Ectopic pregnancy rates remained unchanged. In men, chlamydia testing rates increased nearly 3.5-fold, from 12 to 42 tests per 1000 py. Chlamydia rates for men also rose significantly throughout the study interval (from 91 cases/100,000 py to 218/100,000; P < 0.01) as did urethritis diagnosis rates (P < 0.01). CONCLUSION: Between 1997 and 2007, annual health plan chlamydia rates increased significantly for both women and men. These trends may be due in part to increased testing rates and increased use of more sensitive tests, but they likely do not explain the increased urethritis rates. During this same interval, we observed steady declines in PID rates, consistent with other national data sources.

BACKGROUND: Chlamydia screening practices, positivity, and trends from 2004 to 2009 in publicly funded prenatal clinics have not been described. METHODS: A phone-based survey assessing chlamydia screening practices was conducted among a random sample of clinics providing prenatal services (prenatal, family planning, and integrated clinics: "prenatal clinics") that reported data to the Infertility Prevention Project (IPP) in 2008. Using existing IPP data, chlamydia positivity and trends were assessed among women aged 15 to 24 years seeking care in any prenatal clinic reporting ≥3 years of data to IPP from 2004 to 2009. Linear trends of the effect of year (a continuous variable) on positivity were evaluated using a correlated modeling approach with a random intercept where the unit of analysis was the individual clinic performing chlamydia tests (clinic-based analysis). Covariates included race, age, test technology, and geography. RESULTS: Of 210 sampled clinics, 166 (79%) completed the survey. Of these, 163 (98.2%) had documented chlamydia screening criteria. Most clinics screened all women during their first trimester and reported 100% screening coverage. From 2004 to 2009, 267,416 tests among women aged 15 to 24 years were reported to IPP from eligible prenatal clinics. Overall chlamydia positivity was 8.3%. Controlling for all covariates, positivity decreased from 2004 to 2009 (odds ratio: 0.93 per year, 95% confidence interval: 0.92, 0.95, 35% decrease overall). CONCLUSIONS: The substantial burden of chlamydia among young women tested in prenatal clinics reporting data to IPP suggests the continued need for routine screening. Decreasing trends from 2004 to 2009 in the IPP prenatal population correspond to findings of overall decreasing chlamydia prevalence in the United States.

BACKGROUND: We report the first population-based assessment of national trends in chlamydia prevalence in the United States. METHODS: We investigated trends in chlamydia prevalence in representative samples of the U.S. population aged 14 to 39 years using data from five 2-year survey cycles of the National Health and Nutrition Examination Survey from 1999 to 2008. Prevalence estimates and 95% confidence intervals (CI) are reported stratified by age, gender, and race/ethnicity. Percent change in prevalence over this time period was estimated from regression models. RESULTS: In the 2007-2008 cycle, chlamydia prevalence among participants aged 14 to 39 years was 1.6% (95% CI: 1.1%-2.4%). Prevalence was higher among females (2.2%, 95% CI: 1.4%-3.4%) than males (1.1%, 95% CI: 0.7%-1.7%). Prevalence among non-Hispanic black persons was 6.7% (95% CI: 4.6%-9.9%) and was 2.5% (95% CI: 1.6%-3.8%) among adolescents aged 14 to 19 years. Over the five 2-year cycles, there was an estimated 40% reduction (95% CI: 8%-61%) in prevalence among participants aged 14 to 39 years. Decreases in prevalence were notable in men (53% reduction, 95% CI: 19%-72%), adolescents aged 14 to 19 years (48% reduction, 95% CI: 11%-70%), and adolescent non-Hispanic black persons (45%, reduction, 95% CI: 4%-70%). There was no change in prevalence among females aged 14 to 25 years, the population targeted for routine annual screening. CONCLUSIONS: On the basis of population estimates of chlamydia prevalence, the overall chlamydia burden in the United States decreased from 1999 to 2008. However, there remains a need to reduce prevalence in populations most at risk and to reduce racial disparities.

The authors applied a time-series approach to assess the temporal trend of racial disparity in chlamydia prevalence between young, socioeconomically disadvantaged blacks and whites entering the US National Job Training Program. Racial disparity was defined as the arithmetic difference between age group-, specimen type-, and region of residence-standardized chlamydia prevalences in blacks and whites. A regression with autoregressive moving average errors model was employed to adjust for serial correlation. Data from 46,849 women (2006-2008) and 136,892 men (2004-2008) were analyzed. Racial disparity significantly decreased among women (by an average of 0.122% per 2-month interval; P < 0.05) but not among men (-0.010%, P = 0.57). Chlamydia prevalence significantly declined for black women (-0.139% per 2-month interval; P = 0.004), black men (-0.045%, P < 0.001), and white men (-0.035%, P = 0.002) but not for white women (-0.028%, P = 0.413). Despite the decreases among black women and black men, the black-white disparities remained high for both sexes; in 2008, the racial disparity was 8.1% (95% confidence interval: 6.8, 9.3) for women and 9.0% (95% confidence interval: 8.4, 9.6) for men. These findings suggest that current chlamydia control efforts may be reaching young black men and women but need to be scaled up or modified to address the excess risk among blacks.

OBJECTIVE: To examine the epidemiology of young women screened for gonorrhoea in the USA. METHODS: Data on tests for gonorrhoea among women aged 15-24 years attending family planning clinics from 2005 to 2007 were obtained through the infertility prevention project. Clinics testing 90% or more of women for gonorrhoea and sending 50 or more gonorrhoea tests per year were included. Gonorrhoea positivity on a state and county level was calculated and compared by age and race/ethnicity. RESULTS: A total of 1,119,394 tests from 948 clinics was eligible for inclusion. Median state-specific gonorrhoea positivity was 1.3% (IQR 0.7-2.0%). Positivity was higher among women aged 15-19 years (1.4%, IQR 0.9-2.6%) than among those aged 20-24 years (1.1%, IQR 0.6-1.4%, p=0.03) and among non-Hispanic black women (3.8%, IQR 3.2-4.6%) than non-Hispanic white women (0.6%, IQR 0.4-0.8%, p<0.0001). Half of all gonorrhoea cases in these women originated from 57 of 753 counties. Among non-Hispanic white women, positivity was 2.0% or greater in 4% of counties, while 83% of counties had gonorrhoea positivity of less than 1.0%. Gonorrhoea positivity among non-Hispanic black women was 2.0% or greater in 58% of counties, and less than 1.0% in only one-third of counties. These disparities were present diffusely across the geographical areas included in this analysis. CONCLUSIONS: Gonorrhea positivity was consistently high for young non-Hispanic black women attending family planning clinics across multiple geographical regions. A large proportion of gonorrhoea morbidity was concentrated in a relatively small number of counties in the USA among this population of young women.

BACKGROUND: Annual chlamydia screening is recommended for all sexually active women aged <25 years. Substantial limitations exist in ascertaining chlamydia trends. Reported case rates have increased likely due to increased screening and improved test technology. Other data suggest that prevalence has decreased. METHODS: Data from the Infertility Prevention Project (IPP), a national chlamydia screening program, were used to assess trends in chlamydia positivity from 2004 to 2008 among women aged 15 to 24 years who were tested in family planning clinics reporting data to IPP. Using the clinic as the unit of analysis, a correlated, longitudinal data analysis with a random intercept was conducted among clinics reporting ≥3 years of data during the analysis timeframe. Sensitivity analyses were performed to address the impact of various clinic participation levels in addition to the assessment of various correlation structures. RESULTS: Over 5 million chlamydia tests were reported to IPP family planning clinics from 2004 to 2008. A majority of tests were conducted among white women (clinic-specific mean: 63.2%, interquartile range: 37.6%-91.5%); the clinic-specific mean percent of tests conducted among black women was 17.9% (interquartile range: 0.8%-25.7%). Overall chlamydia positivity from 2004 to 2008 was 7.0%. The odds ratio associated with a single year change (1.00; 95% confidence interval: 0.99, 1.00) suggested that chlamydia positivity did not change from 2004 to 2008, after controlling for clinic-specific population factors (age, race, test usage, and geography). CONCLUSIONS: Findings support previous analyses suggesting that chlamydia prevalence is not increasing despite apparent increasing rates based on case reports.

ICD-9 codes are conventionally used to identify pelvic inflammatory disease (PID) from administrative data for surveillance purposes. This approach may include non-PID cases. To refine PID case identification among women with ICD-9 codes suggestive of PID, a case-finding algorithm was developed using additional variables. Potential PID cases were identified among women aged 15-44 years at Group Health (GH) and Kaiser Permanente Colorado (KPCO) and verified by medical record review. A classification and regression tree analysis was used to develop the algorithm at GH; validation occurred at KPCO. The positive predictive value (PPV) for using ICD-9 codes alone to identify clinical PID cases was 79%. The algorithm identified PID appropriate treatment and age 15-25 years as predictors. Algorithm sensitivity (GH = 96.4%; KPCO = 90.3%) and PPV (GH = 86.9%; KPCO = 84.5%) were high, but specificity was poor (GH = 45.9%; KPCO = 37.0%). In GH, the algorithm offered a practical alternative to medical record review to further improve PID case identification.
