RESUMO
BACKGROUND: Acute kidney injury (AKI) is common among hospitalized patients with community-acquired pneumonia (CAP). We aimed to estimate and compare the risk of AKI for various antibiotic combinations in adults hospitalized for CAP. METHODS: We conducted a retrospective cohort study of the Premier Healthcare Database containing all admissions for 660 US hospitals from 2010 to 2015. We included adults aged ≥18 years hospitalized with CAP and considered 6 different antibiotic combinations based on continuous use in the first 3 hospital days. The primary outcome was incident AKI, defined by ICD-9 codes 584.5-584-9. We evaluated associations of AKI with in-hospital mortality and length-of-stay. We excluded patients who were admitted directly to the intensive care unit, had AKI codes present on admission or had dialysis in the first 2 days. We used generalized linear mixed models with the hospital as a random effect and covariate adjustment for patient demographics, comorbidities, other treatments on day 0/1, and hospital characteristics. RESULTS: The total sample included 449,535 patients, 3.15% of whom developed AKI. All other regimens but fluoroquinolones exhibited higher AKI odds than 3rd generation cephalosporin with or without macrolide. The combination of piperacillin/tazobactam and vancomycin with or without other antibiotics was associated with the highest AKI odds (OR = 1.89; 95% CI: 1.73-2.06). Patients with incident AKI had an increased odds of hospital mortality (OR = 6.37; 95% CI: 6.07-6.69) and longer length-of-stay (mean multiplier = 1.84; 95% CI: 1.82, 1.86). CONCLUSION: Compared to 3rd generation cephalosporin with or without macrolide, piperacillin/tazobactam, vancomycin, and their combination were associated with higher odds of developing AKI, which in turn were associated with worse clinical outcomes.

Individuals with atherosclerotic cardiovascular disease (ASCVD) often have a high burden of comorbidities. Social determinants of health (SDOH) may complicate adherence to treatment in these patients. This study assessed the association of comorbidities and SDOH among individuals with ASCVD. Cross-sectional data from the 2016 to 2019 Behavioral Risk Factor Surveillance System, a nationally representative US telephone-based survey of adults ages ≥18 years, were used. Cardiovascular comorbidities included hypertension, hyperlipidemia, diabetes mellitus, current cigarette smoking, and chronic kidney disease. Non-cardiovascular comorbidities included chronic obstructive pulmonary disease, asthma, arthritis, cancer, and depression. SDOH associated with being at or above the 75th percentile of comorbidity burden were analyzed using multivariable adjusted logistic regression models. The study population included 387,044 individuals, 9% of whom had ASCVD. The mean (SD) numbers of total, cardiovascular, and non-cardiovascular comorbidities were 1.97 (1.27), 1.28 (0.74), 0.69 (0.91) among those without ASCVD and 3.28 (1.62), 1.73 (0.91), and 1.54 (1.22) among those with ASCVD, respectively (P < 0.001 for all comparisons). Female gender, household income ≤$75,000, being unemployed, and difficulty accessing health care were significantly associated with a higher burden of comorbidities among those with ASCVD. The mean (SD) numbers of comorbidities for those with 0, 1, 2, and ≥3 of the aforementioned SDOH were 2.89 (1.45), 2.86 (1.47), 3.39 (1.58), and 4.01 (1.73), respectively (P < 0.001). Among persons with ASCVD, the burden of cardiovascular and non-cardiovascular comorbidities is directly proportional to SDOH in any given individual. Clinicians should address SDOH when managing high-risk individuals.

BACKGROUND: Prognostic factors after dialysis initiation among older chronic kidney disease (CKD) patients are not well studied. In this study, we examined the risk factors associated with 1-year mortality after dialysis initiation among older CKD patients. METHODS: In this retrospective study, we included 621 CKD patients from an electronic medical record based CKD registry that was linked to the United States Renal Data System data. In terms of age, they were all ≥65. We examined the associations of various demographic factors, comorbid conditions, relevant laboratory parameters, the presence of arteriovenous fistula, and inability to take care of oneself with 1-year mortality after dialysis initiation using Cox proportional hazards model. RESULTS: In our study cohort, 224 older patients died during the first year of dialysis initiation and the estimated survival at 1 year was 65% (95% CI 62-69). After adjusting for covariates, increasing age by each year (Hazard ratio 1.04 [95% CI 1.02-1.06]), congestive heart failure (CHF; 1.57 [1.13-2.18]), an absence of AVF (3.0 [1.7-5.1]) and lack of nephrology care prior to dialysis initiation (1.93 [1.39-2.70]) were associated with increased risk of 1-year mortality. Nearly 60% of deaths were due to non-cardiovascular (CV) causes including cancer. CONCLUSION: Risk factors portending high 1-year mortality in older CKD patients are increasing age, CHF, an absence of AVF, and lack of pre-dialysis nephrology care. Clinicians need to be aware of non-CV risks of high mortality in these patients.
