OBJECTIVE To estimate direct medical costs and average lifetime cost per case of pelvic inflammatory disease (PID). METHODS We estimated the direct medical expenditures for PID and its three major sequelae (chronic pelvic pain, ectopic pregnancy, and infertility) and determined the average lifetime cost of a case of PID and its sequelae. We analyzed 3(More)
OBJECTIVES Although sexually transmitted diseases (STDs) cause tremendous health and economic burdens in our society, awareness and knowledge regarding STDs remain poor among health care providers. To examine missed opportunities for STD-related counseling, diagnosis and treatment, we investigated how frequently U.S. adults reported being asked about STDs(More)
To determine whether the simultaneous, partial repeal of needle prescription and drug paraphernalia laws in Connecticut affected purchasing and usage of needles and syringes (syringes) by injecting-drug users (IDUs) and risk of needlestick injuries to police officers, we conducted two serial cross-sectional surveys with IDUs recruited in drug treatment(More)
This article presents evidence that sexually transmitted disease (STD) rates are responsive to increases in alcohol taxes and in the drinking age. The presumed relationship is that a more restrictive alcohol policy reduces alcohol consumption, which in turn decreases risky sexual activity. Reduced-form regressions of STD rates on state alcohol taxes for the(More)
BACKGROUND In October 2008, the Centers for Medicare and Medicaid Services (CMS) discontinued additional payments for certain hospital-acquired conditions that were deemed preventable. The effect of this policy on rates of health care-associated infections is unknown. METHODS Using a quasi-experimental design with interrupted time series with comparison(More)
OBJECTIVES To characterize recent HIV seroconverters in a sexually transmitted disease (STD) clinic population, and examine changing transmission patterns. METHODS We conducted a case-control study nested within a retrospectively defined cohort of individuals attending Baltimore STD clinics between January 1988 and July 1990. Seroconverters, who tested(More)
In May 1992, the Connecticut legislature passed new laws aimed at increasing injecting drug users' (IDUs) access to sterile needles and syringes (syringes); as of July 1992, pharmacists were permitted to sell and individuals were permitted to possess up to 10 syringes without medical prescriptions (nonprescription syringes). We evaluated the impact of the(More)
To determine what factors distinguish medical students who choose primary care careers, 381 graduating medical students at eight New England medical schools were surveyed by questionnaire prior to the 1988 National Resident Matching Program. Students were asked to indicate the degrees of influence that various factors had on their specialty choices, using a(More)
BACKGROUND New rapid HIV antibody tests have allowed provision of results and result-specific counseling on the day on initial visit, and have the potential to increase the efficiency of HIV counseling and testing. METHODS To evaluate the use of rapid testing with same-day results in public clinics, the Single Use Diagnostic System HIV-1 rapid assay was(More)
BACKGROUND AND OBJECTIVES Screening tests for detection of Chlamydia trachomatis include those processed in laboratories and those designed to be processed at the point of care. The latter tests can yield results at the time of the initial patient visit, but most available lab-processed tests have greater sensitivity. In settings where a proportion of(More)
