RESUMO
BACKGROUND: Targeted partner notification (PN), or limiting PN to groups in which efforts are most successful, has been suggested as a potentially cost-effective alternative to providing PN for all syphilis case-patients. The purpose of this study was to identify index case characteristics associated with highest yield partner elicitation and subsequent case finding to determine whether some groups could be reasonably excluded from PN efforts. METHODS: We examined index case characteristics and PN metrics from syphilis case management records of 4 sexually transmitted disease control programs--New York City, Philadelphia, Texas, and Virginia. Partner elicitation was considered successful when a case-patient named 1 or more partners during interview. Case finding was considered successful when a case-patient had 1 or more partners who were tested and had serologic evidence of syphilis exposure. Associations between case characteristics and proportion of pursued case-patients with successful partner elicitation and case finding were evaluated using χ2 tests. RESULTS: Successful partner elicitation and new case finding was most likely for index case-patients who were younger and diagnosed at public sexually transmitted disease clinics. However, most characteristics of index case-patients were related to success at only a few sites, or varied in the direction of the relationship by site. Other than late latent case-patients, few demographic groups had a yield far below average. CONCLUSIONS: If implemented, targeted PN will require site-specific data. Sites may consider eliminating PN for late latent case-patients. The lack of demographic groups with a below average yield suggests that sites should not exclude other groups from PN.

We surveyed selected public sexually transmitted disease clinics in the United States regarding human papillomavirus vaccine availability, target populations, funding sources, and barriers. Although nearly all had experience offering other vaccines, only 7 of 42 clinics (17%) offered human papillomavirus vaccine. Vaccine cost, staff time, and follow-up issues were commonly reported barriers.

OBJECTIVES: We evaluated the impact of revised national treatment recommendations on fluoroquinolone use for gonorrhea in selected states. METHODS: We evaluated gonorrhea cases reported through the Sexually Transmitted Disease Surveillance Network as treated between July 1, 2006 and May 31, 2008, using interrupted time series analysis. Outcomes were fluoroquinolone treatment overall, by area, and by practice setting. RESULTS: Of 16,126 cases with treatment dates in this period, 15,669 noted the medication used. After revised recommendations were released, fluoroquinolone use decreased abruptly overall (21.5%; 95% confidence interval [CI] = 15.9%, 27.2%), in most geographic areas evaluated, and in sexually transmitted disease clinics (28.5%; 95% CI = 19.0%, 37.9%). More gradual decreases were seen in primary care (8.6%; 95% CI = 2.6%, 14.6%), and in emergency departments, urgent care, and hospitals (2.7%; 95% CI = 1.7%, 3.7%). CONCLUSIONS: Fluoroquinolone use decreased after the publication of revised national guidelines, particularly in sexually transmitted disease clinics. Additional mechanisms are needed to increase the speed and magnitude of changes in prescribing in primary care, emergency departments, urgent care, and hospitals.

Data to guide programmatic decisions in public health are needed, but frequently epidemiologists are limited to routine case report data for notifiable conditions such as sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV). However, case report data are frequently incomplete or provide limited information on comorbidity or risk factors. Supplemental data often exist but are not easily accessible, due to a variety of real and perceived obstacles. Data matching, defined as the linkage of records across two or more data sources, can be a useful method to obtain better or additional data, using existing resources. This article reviews the practical considerations for matching STD and HIV surveillance data with other data sources, including examples of how STD and HIV programs have used data matching.
RESUMO
OBJECTIVE: Integrated infectious disease surveillance information systems have the potential to provide important new surveillance capacities and business efficiencies for local health departments. We conducted a case study at a large city health department of the primary computer-based infectious disease surveillance information systems during a 10-year period to identify the major challenges for information integration across the systems. METHODS: The assessment included key informant interviews and evaluations of the computer-based surveillance information systems used for acute communicable diseases, human immunodeficiency virus/acquired immunodeficiency syndrome, sexually transmitted diseases, and tuberculosis. Assessments were conducted in 1998 with a follow-up in 2008. Assessments specifically identified and described the primary computer-based surveillance information system, any duplicative information systems, and selected variables collected. RESULTS: Persistent challenges to information integration across the information systems included the existence of duplicative data systems, differences in the variables used to collect similar information, and differences in basic architecture. CONCLUSIONS: The assessments identified a number of challenges for information integration across the infectious disease surveillance information systems at this city health department. The results suggest that local disease control programs use computer-based surveillance information systems that were not designed for data integration. To the extent that integration provides important new surveillance capacities and business efficiencies, we recommend that patient-centric information systems be designed that provide all the epidemiologic, clinical, and research needs in one system. In addition, the systems should include a standard system of elements and fields across similar surveillance systems.
RESUMO
OBJECTIVE: Advancements in technology, such as geographic information systems (GIS), expand sexually transmitted disease (STD) program capacity for data analysis and visualization, and introduce additional confidentiality considerations. We developed a survey to examine GIS use among STD programs and to better understand existing data confidentiality practices. METHODS: A Web-based survey of eight to 22 questions, depending on program-specific GIS capacity, was e-mailed to all STD program directors through the National Coalition of STD Directors in November 2004. Survey responses were accepted until April 15, 2005. RESULTS: Eighty-five percent of the 65 currently funded STD programs responded to the survey. Of those, 58% used GIS and 54% used geocoding. STD programs that did not use GIS (42%) identified lack of training and insufficient staff as primary barriers. Mapping, spatial analyses, and targeting program interventions were the main reasons for geocoding data. Nineteen of the 25 programs that responded to questions related to statistical disclosure rules employed a numerator rule, and 56% of those used a variation of the "Rule of 5." Of the 28 programs that responded to questions pertaining to confidentiality guidelines, 82% addressed confidentiality of GIS data informally. CONCLUSIONS: Survey findings showed the increasing use of GIS and highlighted the struggles STD programs face in employing GIS and protecting confidentiality. Guidance related to data confidentiality and additional access to GIS software and training could assist programs in optimizing use of spatial data.
RESUMO
OBJECTIVES: We assessed the added value of using a geocoder to improve sexually transmitted disease (STD) surveillance data and decision support through redistribution of inaccurately assigned morbidity in Richmond, Virginia. METHODS: Virginia initiated geocoding of STD data as a data quality tool in 2002. Geocoded output files were assessed and discordant proportions of reported gonorrhea and chlamydia morbidity were reassigned appropriately for the city of Richmond, Chesterfield County, and Henrico County (2002 to 2006). We used Chi-square analysis to compare assignment proportions and calculated crude odds ratios for 2006 data to estimate increased case reassignment likelihood. RESULTS: From 2002 to 2006, 149,229 cases of gonorrhea and chlamydia were reported within the Commonwealth of Virginia. Of the reported morbidity, 81% of cases (n=120,875) were successfully geocoded; 7% (n=8,461) of geocoded addresses were reassigned. Approximately 76% (n=6,412) of all reassigned cases occurred within Richmond and Chesterfield and Henrico counties. In 2006, 84% (n=654) of reassigned cases in this tri-city/county area were initially reported as Richmond morbidity. Data quality improvements reduced Richmond's artificially inflated morbidity by 18% and increased Chesterfield and Henrico morbidity by 17% and 55%, respectively. Richmond morbidity was three times more likely to be reassigned than Chesterfield cases (odds ratio [OR] = 2.93, 95% confidence interval [CI] 2.21, 3.90), and two times more likely than Henrico cases (OR=2.12, 95% CI 1.63, 2.76). Richmond's number one national rank for STD rates was reduced beginning in 2002. CONCLUSIONS: Declining rates of STDs were statistically associated with geocoded morbidity reassignments. Implementation of this data quality business process has improved epidemiologic analyses, prevention planning, and assessment of resource allocations. The reduction in Richmond's national STD rankings is indicative of the effect geocoding can have on surveillance data.
RESUMO
OBJECTIVES: We investigated the effect of providing mailing cost reimbursements to local health departments on the timeliness of the reporting of sexually transmitted diseases (STDs) in Virginia. METHODS: The Division of Disease Prevention, Virginia Department of Health, provided mailing cost reimbursements to 31 Virginia health districts from October 2002 to December 2004. The difference (in days) between the diagnosis date (or date the STD paperwork was initiated) and the date the case/STD report was entered into the STD surveillance database was used in a negative binomial regression model against time (as divided into three periods-before, during, and after reimbursement) to estimate the effect of providing mailing cost reimbursements on reporting timeliness. RESULTS: We observed significant decreases in the number of days between diagnosis and reporting of a case, which were sustained after the reimbursement period ended, in 25 of the 31 health districts included in the analysis. We observed a significant initial decrease (during the reimbursement period) followed by a significant increase in the after-reimbursement phase in one health district. Two health districts had a significant initial decrease, while one health district had a significant decrease in reporting timeliness in the period after reimbursement. Two health districts showed no significant changes in the number of days to report to the central office. CONCLUSION: Providing reimbursements for mailing costs was statistically associated with improved STD reporting timeliness in almost all of Virginia's health districts. Sustained improvement after the reimbursement period ended is likely indicative of improved local health department reporting habits.
