Social Vulnerability Indices as a Risk Factor for Heart Failure Readmissions.

Objectives: The objective of our study was to use the parameters of social vulnerability index (SVI) to observe their association with the 30-day hospital readmissions in the heart failure population.Methods: Data required for analysis were extracted from the electronic medical record. The geographic SVI data was then merged with the clinical data. Qualitative variables and reported as frequency and quantitative variables and reported as the mean ± standard deviation. Variables from univariate analysis with a P value of ≤ 0.10 were evaluated using multivariate logistic regression with stepwise backward variable selection and receiver operating curve (ROC) analysis.Results: The odds ratio of readmission predicted by HOSPITAL score was 1.137 (P value = 0.004, 95% CI = 1.041-1.241). SVI parameter recording disability showed odds ratio of 1.521 (P value = 0.006, 95% CI = 1.125-2.058) and SVI parameter tracking vehicle ownership showed odds ratio of 15.355 (P value = 0.014, 95% CI = 1.755 - 134.383). The ROCs were generated for three scenarios: (i) HOSPITAL score only which had area under the curve (AUC) of 0.702 (P value = 0.015), (ii) SVI indicators tracking vehicle ownership and disability resulted in the AUC of 0.589 (P value = 0.016), and (iii) all of the above combined increased the AUC increased to 0.718 (P value = 0.015).Conclusions: Two social parameters (limited vehicle access and prevalence of disability) from the SVI showed a strong association with 30-day hospital readmissions.

An assessment of race and gender-based biases among readmission predicting tools (HOSPITAL, LACE, and RAHF) in heart failure population.

BACKGROUND: The objective of our study is to retrospectively investigate if the HOSPITAL score, LACE index, and RAHF scale exhibit any bias based on gender and race in heart failure readmissions. METHODS: This is a retrospective cohort study with all adult medical patients discharged with congestive heart failure from 2016 to 2018 from Southern Illinois University School of Medicine Hospitalist service. The receiver operating characteristic (ROC) curve was constructed comparing prediction tools (HOSPITAL score, LACE index, and RAHF scale) performance based on gender and race by measuring the area under the curve (AUC). Absolute Between-ROC Area (ABROCA) values were calculated. All statistical analyses were performed using R version 3.6.2. RESULTS: The performance of the HOSPITAL score in the majority and minority population showed a statistically significant difference between AUCs (0.714 and 0.633, p = 0.029) and an ABROCA of 0.081 indicating superior performance in predicting hospital readmissions in the majority group vs. the minority. The performance of RAHF score in females and males showed statistically significant differences between AUCs (0.567 and 0.527, p = 0.04) and an ABROCA of 0.04 indicating the superior performance of the RAHF score in females compared with males. CONCLUSIONS: Our study demonstrated that the HOSPITAL score and the RAHF scale showed significant differences in predicting 30-day readmissions risk based on race and gender, respectively, in heart failure patients, whereas the LACE index did not show any significant difference.

Pulmonary Blastomycosis: A case series and review of unique radiological findings.

Blastomycosis is a systemic fungal infection which primarily involves the lungs but can disseminate to involve extrapulmonary sites. Current testing that exists includes sputum, urine, serum, and pathological tissue analysis. Radiological testing is often non-specific and highly variable. Here we present five cases of pulmonary blastomycosis with challenging radiographic presentations.

Meta-Analysis Evaluating Outcomes of Surgical Left Atrial Appendage Occlusion During Cardiac Surgery.

Surgical left atrial appendage occlusion (S-LAAO) has become a common procedure performed in patients undergoing cardiac surgery; however, evidence to support this procedure remains inconclusive. This meta-analysis aims to assess the efficacy of S-LAAO in terms of ischemic stroke, postoperative atrial fibrillation, and all-cause mortality. A thorough literature review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. We identified 10 relevant studies for our meta-analysis. It included 6,779 patients who underwent S-LAAO and 6,573 who did not undergo LAAO. In terms of ischemic stroke, the S-LAAO cohort had a lower events (pooled odds ratio [OR] 0.655 (0.518 to 0.829), p = 0.0004) compared with the non-LAAO cohort. S-LAAO cohort also had lower events of all-cause mortality (pooled OR 0.74 (95% confidence interval 0.55 to 0.99), p = 0.0408) when compared with the non-LAAO cohort. In regards to postoperative atrial fibrillation, there was no difference between the 2 groups (pooled OR 1.29 (95% confidence interval 0.81 to 2.06), p = 0.2752). In conclusion, S-LAAO was associated with lower events of ischemic stroke or systemic embolism and all-cause mortality when compared to the non-LAAO group.
