Does poverty increase antibiotic prescribing rates through underlying health conditions? Ecological study using parallel mediation analysis.

Objective: Effect of social determinants on antibiotic prescribing rates is poorly studied in modern literature. The objective of this study was to explore the effect of the prevalence of poverty (annual household income <$24,999) in each state on antibiotic prescribing rates in outpatient settings per 1,000 population through chronic health conditions (ie, prevalence of obesity, diabetes, and chronic obstructive pulmonary disease) while also adjusting for confounders (ie, prevalence of population aged ≥65 years and physician density in each state). Design: Ecological study. Participants: Entire US population. Methods: Prevalence estimates from all 51 states were used to calculate direct, indirect, and total effects of poverty on the rates of antibiotic prescribing through parallel mediation analysis using linear regression with chronic health conditions (obesity, diabetes, and chronic obstructive pulmonary disease) as mediators. I obtained these data from point-prevalence estimates of 2020 survey results from the Behavioral Risk Factor Surveillance System for rates on poverty, obesity, diabetes, chronic obstructive pulmonary disease, and population aged ≥ 65 years. I also used the Antibiotic Resistance & Patient Safety Portal for antibiotic prescribing rates per 1,000 population and the Association of American Medical Colleges database for the physician density per 100,000 population. Results: For every percentage increase in prevalence of poverty in each state, the antibiotic prescribing rate increased by 17.4 courses per 1,000 population (95% bootstrap confidence interval, 9.2-24.9) using indirect effects of poverty through mediators. Conclusions: Antibiotic stewardship programs should consider targeting social determinants of health along with underlying health conditions of patients being treated with antibiotics.

Alcohol-attributable deaths and years of potential life lost--11 States, 2006-2010.

Excessive alcohol consumption, the fourth leading preventable cause of death in the United States, resulted in approximately 88,000 deaths and 2.5 million years of potential life lost (YPLL) annually during 2006-2010 and cost an estimated $223.5 billion in 2006. To estimate state-specific average annual rates of alcohol-attributable deaths (AAD) and YPLL caused by excessive alcohol use, 11 states analyzed 2006-2010 data (the most recent data available) using the CDC Alcohol-Related Disease Impact (ARDI) application. The age-adjusted median AAD rate was 28.5 per 100,000 population (range = 50.9 per 100,000 in New Mexico to 22.4 per 100,000 in Utah). The median YPLL rate was 823 per 100,000 (range = 1,534 YPLL per 100,000 for New Mexico to 634 per 100,000 in Utah). The majority of AAD (median = 70%) and YPLL (median = 82%) were among working-age (20-64 years) adults. Routine monitoring of alcohol-attributable health outcomes, including deaths and YPLL, in states could support the planning and implementation of evidence-based prevention strategies recommended by the Community Preventive Services Task Force to reduce excessive drinking and related harms. Such strategies include increasing the price of alcohol, limiting alcohol outlet density, and holding alcohol retailers liable for harms related to the sale of alcoholic beverages to minors and intoxicated patrons (dram shop liability).

Traditional risk factors for Helicobacter pylori infection not found among patients undergoing diagnostic upper endoscopy-Republic of Georgia, 2007-2008.

OBJECTIVES: Helicobacter pylori causes gastritis, duodenal ulcers, and gastric cancer. Although household crowding, low socioeconomic status (SES), and poor sanitation are associated with infection elsewhere, risk factors of infection in the Republic of Georgia (ROG), a country with a high prevalence rate (>70%), remain unknown. In this study we explored potential risk factors of infection among symptomatic patients in ROG. METHODS: During 2007-2008, we prospectively recruited 390 subjects with gastrointestinal symptoms referred to five tertiary care centers for diagnostic upper endoscopy. We administered a questionnaire on potential risk factors and tested patients using three diagnostic tests: gastric biopsies underwent histological evaluation and rapid urease test (CLO test), and an ELISA was used to detect IgG against H. pylori in serum. We defined a case as having two or more positive results from the three available tests. Univariate and multivariate logistic regression analyses were performed. RESULTS: Overall, 217 (56%) patients met the study case definition. Subjects diagnosed with cancer had the highest rate of H. pylori infection (62%), followed by those with gastritis (55%), and ulcer (54%). Age >30 years (adjusted odds ratio (aOR 2.6, 95% confidence interval (CI) 1.6-4.3) and residing in the capital city (aOR 0.6, 95% CI 0.4-0.9) were significantly associated with infection. CONCLUSIONS: In this large cohort with gastrointestinal symptoms, only age >30 years and living in the capital were significant factors associated with infection. Lower SES, less education, and crowding did not confer an increased risk, in contrast to the findings of previous studies. Population-based studies are needed to identify potential routes and risk factors of H. pylori infection in ROG.

Long-term outcomes of 217 botulism cases in the Republic of Georgia.

BACKGROUND: The acute paralytic syndrome of botulism has been well-described; however, little is known about its long-term consequences. METHODS: We conducted a case-control study in the Republic of Georgia to evaluate the health of patients > or =6 months after they had experienced an episode of botulism. Case patients were selected on the basis of who had had a clinical diagnosis of foodborne botulism reported to the national surveillance system from 1998 through 2003. Three control subjects were randomly selected from each patient's community. RESULTS: We located 217 patients who had had botulism from surveillance records, with a median time since onset of illness of 4.3 years. The median age was 37 years, and 49% of the patients were female, similar to the control subjects. Most of the patients (68%) had acquired botulism from home-conserved vegetables (probably containing toxin type B), 15% had been hospitalized for >1 month, and 25% had required mechanical ventilation. Six patients died. Of the remaining 211 patients, 68% reported having worse health at the time of the interview than 6 years before the interview, compared with 17% of 656 control subjects (matched odds ratio, 17.6; 95% confidence interval, 10.9-28.4). Overall, 49% of the patients reported their current health as "fair" or "poor," versus 25% of the control subjects (odds ratio, 5.0; 95% confidence interval, 3.2-7.6). Patients were more likely than control subjects to report fatigue, weakness, dizziness, dry mouth, and difficulty lifting objects (P<.05, for each). Patients were more likely than control subjects to report difficulty breathing caused by moderate exertion (P<.001) but not by minimal exertion or at rest. Patients were also more likely to report being limited in vigorous activities, walking 3 blocks, and climbing 3 flights of stairs (P<.05, for each). Finally, patients reported feeling significantly worse than control subjects for 6 of 11 questions regarding psychosocial well-being (P<.05, for each). In a multivariable model involving patients who had had botulism, mechanical ventilation during acute illness, older age, and region of residence independently predicted worse health. CONCLUSIONS: Several years after acute botulism, patients reported significant health, functional, and psychosocial limitations that are likely to be consequences of the illness.
