- Abstract
Introduction: Persistent disparities in influenza vaccination rates exist between racial/ethnic minorities and Whites. The mechanisms that define this relationship are under-researched., Methods: Surveys assessing barriers to vaccination were administered to outpatients in a rural medical center in Southeastern Louisiana. Survey responses were matched to patient medical records. Likert-style statements were used to measure barriers to vaccination. A mediation analysis assessing the relationship between race and influenza vaccination mediated by vaccination barriers was conducted., Results: The self-reported influenza vaccination rate in those surveyed was 40.4%. Whites (45.5%) were more likely than racial/ethnic minorities (36.3%) to report receipt of an influenza vaccination (p = 0.02). Racial/ethnic minorities reported significantly higher vaccination barrier scores (p < 0.01). The relationship between race/ethnicity and vaccination was mediated by vaccination barriers, when controlling for provider recommendation and having at least one comorbid medical condition (natural indirect effect [NIE] p-value = 0.02, proportion mediated = 0.71)., Conclusions: Barriers to vaccination mediates the relationship between race/ethnicity and vaccination status. Providers should focus on minimizing fears that the vaccine will cause illness and emphasize that the vaccine is safe and effective at preventing severe influenza-associated illness. Additional efforts should be made to improve accessibility of the influenza vaccine, including addressing costs of vaccination and expanding the number and types of settings where the vaccine is offered., (©2022 Pacini Editore SRL, Pisa, Italy.)

- Abstract
Background: Despite the burden of disease and increased risk of influenza-associated morbidity and mortality among PLWHA, influenza vaccination has been understudied in this population., Methods: We built an 11-year cohort of HIV-infected adults from medical records of PLWHA seeking care within the Louisiana State University medical system from June 2002-June 2013. Influenza vaccination uptake among PLWHA was calculated overall and for each medical facility for each influenza season. Linear regression was used to assess influenza vaccination uptake over time, both overall and by facility. Data were restricted to the final influenza season (2012-13) to assess predictors of PLWHA vaccination. Individuals were nested within medical facilities in order to assess the amount of variability in influenza vaccination rates across medical facilities., Results: Influenza vaccination uptake among PLWHA increased over the study period (p < 0.01). The overall proportion of PLWHA vaccinated during the 2012-13 influenza season was 33.7%. 37.9% of the variability in the model occurred at the facility-level., Conclusions: Although there was an increase in influenza vaccination within the PLWHA cohort over the course of the study, vaccination rates remained low overall. Special efforts must be made to increase vaccination uptake among PLWHA, with particular focus on those within the population who are likely to be at highest risk. The substantial variability at the facility-level indicates that there are unmeasured facility-level factors that contribute significantly to PLWHA vaccination., Competing Interests: Conflict of interest statement None of the authors report any conflict of interest., (©2022 Pacini Editore SRL, Pisa, Italy.)

- Abstract
Introduction: Quitting smoking has been proven to benefit smokers with diabetes. However, among older patients with diabetes, the evidence regarding an association between smoking status and the risk of type 2 diabetes mellitus-related emergency department (ED) visits has not been well investigated., Methods: A retrospective cohort study was performed by using the Louisiana State University Health Care Services Division electronic health records from 2009 to 2011. Patients aged 65 years or older with type 2 diabetes and smoking status recorded at least twice in 2010 were selected. Selected patients with diabetes were classified into nonsmokers, former smokers, continuing smokers, and relapsed smokers. Cox proportional hazards regression models were used to estimate the adjusted hazard ratio (aHR) of 1-year type 2 diabetes-related ED visits for each group compared with nonsmokers., Results: There were 174 (8.2%) continuing smokers and 77 (3.6%) relapsed smokers in 2,114 patients with diabetes who were studied. Rates of type 2 diabetes-related ED visits were highest in relapsed smokers (28.6%). Compared with nonsmokers, relapsed smokers had a significantly higher risk of type 2 diabetes-related ED visits (aHR = 1.62; 95% confidence interval [CI], 1.04-2.50). After stratifying by sex, a significantly increased risk of type 2 diabetes-related ED visits was shown only in male relapsed smokers (aHR = 2.05; 95% CI, 1.13-3.71) and female continuing smokers (aHR = 1.65; 95% CI, 1.10-2.47) compared with nonsmokers., Conclusion: Older men with diabetes who were relapsed smokers had a higher risk of type 2 diabetes-related ED visits. Future research and clinical practice should focus on these patients and create more effective interventions for smoking cessation and diabetes management.

- Abstract
Background: The current methodology for calculating central-line-associated bloodstream infection (CLABSI) rates, used for pay-for-performance measures, does not account for multiple concurrent central lines., Objective: To compare CLABSI rates using standard National Healthcare Safety Network (NHSN) denominators to rates accounting for multiple concurrent central lines., Design: Descriptive analysis and retrospective cohort analysis., Methods: We identified all adult patients with central lines at 2 academic medical centers over an 18-month period. CLABSI rates were calculated for intensive care units (ICUs) and non-ICUs using the standard NHSN methodology and denominator (a patient could only have 1 central-line day for a given patient day) and a modified denominator (number of central lines in 1 patient in 1 day count as number of line days). We also compared characteristics of patients with and without multiple concurrent central lines., Results: Among 18,521 hospital admissions, there were 156,574 central-line days and 239 CLABSIs (ICU, 105; non-ICU, 134). Our modified denominator reduced CLABSI rates by 25% in ICUs (1.95 vs 1.47 per 1,000 line days) and 6% (1.30 vs 1.22 per 1,000 line days) in non-ICUs. Patients with multiple concurrent central lines were more likely to be in an ICU, to have a longer admission, to have a dialysis catheter, and to have a CLABSI., Conclusions: Using the number of central lines as the denominator decreased CLABSI rates in ICUs by 25%. The presence of multiple concurrent central lines may be a marker of severity of illness. The risk of CLABSI per lumen of a central line is similar in ICUs compared to wards.

- Abstract
Objective: The purpose of a curfew is to decrease the amount of crime inflicted on minors during the late hours of the night. On June 1, 1994, a city curfew was instituted in New Orleans, requiring all persons 17 years of age or younger to be off the streets from 9 PM to 6 AM Sunday through Thursday, and from 11 PM to 6 AM on Friday and Saturday. This study evaluated the effect of the curfew on emergency medical services (EMS) transports for patients who were 17 years old or younger (pediatric)., Methods: Data from all pediatric transports were included from the months before (5/94) and after (6/94) the institution of the curfew, and from the same two months one year earlier (5/93 and 6/93). A chi-square test was used to evaluate comparisons., Results: The city EMS transports 48,000 patients per year in a one-tiered system (paramedic only) that acts as the sole provider of emergency EMS transport in the city. Approximately 10% of all transports are pediatric, and 40% of the pediatric transports are for trauma. A total of 1,642 transports were found that fit the inclusion criteria. In May 1993, there were 415 total pediatric transports; 234 were pediatric trauma. In June 1993, there were 406 total pediatric transports; 250 were pediatric trauma. In May 1994, there were 447 total pediatric runs; 243 were pediatric trauma. During the postcurfew month, June 1994, there were a significant decrease in pediatric transports to 370 (p < 0.01) and a significant decrease in pediatric trauma transport to 189 (p < 0.01)., Conclusion: The institution of a curfew may lead to a drop in pediatric EMS runs during curfew hours. Another value of the curfew may be in the secondary effects of the curfew in preventing childhood injury during noncurfew hours.
