Factors associated with state variation in mortality among persons living with diagnosed HIV infection
Krueger AL , Van Handel M , Dietz PM , Williams WO , Satcher Johnson A , Klein PW , Cohen S , Mandsager P , Cheever LW , Rhodes P , Purcell DW . J Community Health 2019 44 (5) 963-973 In the United States, the all-cause mortality rate among persons living with diagnosed HIV infection (PLWH) is almost twice as high as among the general population. We aimed to identify amendable factors that state public health programs can influence to reduce mortality among PLWH. Using generalized estimating equations (GEE), we estimated age-group-specific models (24-34, 35-54, >/= 55 years) to assess the association between state-level mortality rates among PLWH during 2010-2014 (National HIV Surveillance System) and amendable factors (percentage of Ryan White HIV/AIDS Program (RWHAP) clients with viral suppression, percentage of residents with healthcare coverage, state-enacted anti-discrimination laws index) while controlling for sociodemographic nonamendable factors. Controlling for nonamendable factors, states with 5% higher viral suppression among RWHAP clients had a 3-5% lower mortality rates across all age groups [adjusted Risk Ratio (aRR): 0.95, 95% Confidence Interval (CI): 0.92-0.99 for 24-34 years, aRR: 0.97, 95%CI: 0.94-0.99 for 35-54 years, aRR: 0.96, 95%CI: 0.94-0.99 for >/= 55 years]; states with 5% higher health care coverage had 4-11% lower mortality rate among older age groups (aRR: 0.96, 95%CI: 0.93-0.99 for 34-54 years; aRR: 0.89, 95%CI: 0.81-0.97 for >/= 55 years); and having laws that address one additional area of anti-discrimination was associated with a 2-3% lower mortality rate among older age groups (aRR: 0.98, 95%CI: 0.95-1.00 for 34-54 years; aRR: 0.97, 95%CI: 0.94-0.99 for >/= 55 years). The mortality rate among PLWH was lower in states with higher levels of residents with healthcare coverage, anti-discrimination laws, and viral suppression among RWHAP clients. States can influence these factors through programs and policies. |
County-level correlates of CDC-funded HIV testing events, United States, 2012
Hayek S , Heitgerd JL , Williams WO , Krueger AL , Dietz PM . J Community Health 2015 40 (5) 1031-6 HIV prevalence and socio-demographic data were analyzed to assess the alignment of CDC-funded HIV testing activity in 2012 with its high-impact prevention approach. CDC-funded HIV-testing was conducted in counties with high HIV prevalence and in places potentially more affected by HIV as measured by urbanicity, percent black, percent poverty, and percent uninsured. The percent Hispanic/Latino was associated with a lower probability of HIV testing activity. Higher percentages of black and Hispanic/Latino in the population was positively associated with new HIV diagnoses. Analyzing county-level data confirmed the appropriateness of CDC-funded HIV testing activities under a high-impact prevention approach but also suggested areas for possible improvement. |
Clinical outcomes of nalidixic acid, ceftriaxone, and multidrug-resistant nontyphoidal Salmonella infections compared with pansusceptible infections in FoodNet Sites, 2006-2008
Krueger AL , Greene SA , Barzilay EJ , Henao O , Vugia D , Hanna S , Meyer S , Smith K , Pecic G , Hoefer D , Griffin PM . Foodborne Pathog Dis 2014 11 (5) 335-41 BACKGROUND: Nontyphoidal Salmonella causes an estimated 1.2 million infections, 23,000 hospitalizations, and 450 deaths annually in the United States. Most illnesses are self-limited; however, treatment with antimicrobial agents can be life-saving for invasive infections. METHODS: The Foodborne Diseases Active Surveillance Network and the National Antimicrobial Resistance Monitoring System collaborated on a prospective cohort study of patients with nontyphoidal Salmonella bloodstream and gastrointestinal infections to determine differences in the clinical outcomes of resistant compared with pansusceptible infections. Interviews were conducted within 85 days of specimen collection date. RESULTS: Of 875 nontyphoidal Salmonella isolates, 705 (81%) were pansusceptible, 165 (19%) were resistant to at least 1 agent, and 5 (0.6%) had only intermediate resistance. The most common pattern, found in 51 (31%) of resistant isolates, was resistance to at least ampicillin, chloramphenicol, streptomycin, sulfisoxazole, and tetracycline (ACSSuT); 88% of isolates with this pattern were serotype Typhimurium or Newport. Fourteen (52%) of the 27 ceftriaxone-resistant isolates were also ACSSuT resistant. Adjusted for age and serotype, bloodstream infection was significantly more common among patients infected with strains resistant to only two, only three, or only five antimicrobial classes, to ACSSuT with or without other agents, to ACSSuT only, or to nalidixic acid with or without other agents than among patients with pansusceptible isolates. Adjusted for age, serotype, and bloodstream infection, hospitalization was significantly more common among patients infected with strains resistant to only three agents or to ceftriaxone (all ceftriaxone-resistant isolates were resistant to other agents) than among patients with pansusceptible isolates. CONCLUSION: This study extends evidence that patients with antimicrobial-resistant nontyphoidal Salmonella infections have more severe outcomes. Prevention efforts are needed to reduce unnecessary antimicrobial use in patient care settings and in food animals to help prevent the emergence of resistance and infections with resistant nontyphoidal Salmonella. |
Antimicrobial resistance among invasive nontyphoidal Salmonella enterica in the United States, National Antimicrobial Resistance Monitoring System, 1996-2007
Crump JA , Medalla FM , Joyce KW , Krueger AL , Hoekstra RM , Whichard JM , Barzilay EJ . Antimicrob Agents Chemother 2011 55 (3) 1148-54 Nontyphoidal salmonellae (NTS) are important causes of community-acquired bloodstream infection. We describe patterns of antimicrobial resistance among invasive NTS in the United States. We compared bloodstream NTS isolates with those from stool submitted to the National Antimicrobial Resistance Monitoring System (NARMS) from 1996-2007. We described antimicrobial resistance among invasive strains by serogroup and serotype. Of the 19,302 NTS, 17,804 (92.2%) were from stool or blood. Of these, 1,050 (5.9%) were bloodstream isolates. The median age (range) of patients with and without bacteremia was 36 (0, 97) years and 20 (0, 105) years, respectively (p<0.001). Males (OR 1.21, 95% CI 1.06, 1.38) and those aged ≥65 years were at greater risk for invasive disease. Enteritidis, Typhimurium, and Heidelberg were the most common serotypes isolated from blood; Dublin, Sandiego, and Schwarzengrund were associated with the greatest risk for bloodstream isolation. Of invasive isolates 208 (19.8%) were resistant to ampicillin, 117 (11.1%) to chloramphenicol, and 26 (2.5%) to trimethoprim-sulfamethoxazole; 28 (2.7%) isolates were resistant to nalidixic acid and 26 (2.5%) to ceftriaxone. Antimicrobial resistance to traditional agents is common. However, the occurrence of nalidixic acid and ceftriaxone resistance among invasive NTS is cause for clinical and public health vigilance. |
Commensal Escherichia coli isolate resistant to eight classes of antimicrobial agents in the United States
Krueger AL , Folster J , Medalla F , Joyce K , Perri MB , Johnson L , Zervos M , Whichard JM , Barzilay EJ . Foodborne Pathog Dis 2010 8 (2) 329-32 To increase understanding of community-acquired resistance, stool samples from 477 nonhospitalized persons in Maryland and Michigan, from 2004 to 2008, were screened for ceftriaxone resistance. Seven (1.5%) yielded ceftriaxone-resistant Escherichia coli; one isolate was resistant to all eight antimicrobial classes routinely tested: aminoglycosides, beta-lactam/beta-lactamase inhibitor combinations, cephems, penicillins, folate pathway inhibitors, phenicols, quinolones, and tetracyclines. The extensively resistant isolate was from a 50-year-old woman who denied antimicrobial use, hospitalization, or international travel within 6 months. Meat (beef, chicken, and pork) and eggs were consumed within 1 month before stool collection. Further studies are warranted to understand potential sources, including the food supply, of resistant E. coli. |
