Item Characterizing pain leading to emergency medical services activation in heart failure(Wolters Kluwer, 2022) Smith, Asa B.; Jung, Miyeon; Lee, Christopher; Pressler, Susan J.; School of NursingBackground: Pain is a common but understudied symptom among patients with heart failure (HF) transported by emergency medical services (EMS). The aims were to determine explanatory factors of a primary complaint of pain and pain severity, and characterize pain among patients with HF transported by EMS. Methods: Data from electronic health records of patients with HF transported by EMS within a midwestern United States county from 2009 to 2017 were analyzed. Descriptive statistics, χ 2 , analysis of variance, and logistic and multiple linear regression analyses were used. Results: The sample (N = 4663) was predominantly women (58.1%) with self-reported race as Black (57.7%). The mean age was 64.2 ± 14.3 years. Pain was the primary complaint in 22.2% of the sample, with an average pain score of 6.8 ± 3.1 out of 10. The most common pain complaint was chest pain (68.1%). Factors associated with a primary pain complaint were younger age (odds ratio [OR], 0.97; 95% confidence interval [CI], 0.96-0.97), history of myocardial infarction (OR, 1.96; 95% CI, 1.55-2.49), and absence of shortness of breath (OR, 0.67; 95% CI, 0.58-0.77). Factors associated with higher pain severity were younger age ( b = -0.05, SE = 0.013), being a woman ( b = 1.17, SE = 0.357), and White race ( b = -1.11, SE = 0.349). Conclusions: Clinical and demographic factors need consideration in understanding pain in HF during EMS transport. Additional research is needed to examine these factors to improve pain management and reduce transports due to pain.Item Hospital Factors, Performance on Process Measures After Transient Ischemic Attack, and 90-Day Ischemic Stroke Incidence(American Heart Association, 2021) Levine, Deborah A.; Perkins, Anthony J.; Sico, Jason J.; Myers, Laura J.; Phipps, Michael S.; Zhang, Ying; Bravata, Dawn M.; Biostatistics, School of Public HealthBackground and purpose: We determined the association between hospital factors, performance on transient ischemic attack (TIA) process measures, and 90-day ischemic stroke incidence. Methods: Longitudinal analysis of retrospectively obtained data on 9168 veterans ≥18 years with TIA presenting to the emergency department or inpatient unit at 69 Veterans Affairs hospitals with ≥10 eligible patients per year in fiscal years 2015 to 2018. Process measures were high/moderate potency statin within 7 days of discharge, antithrombotic by day 2, and hypertension control (<140/90 mm Hg) at 90 days. The outcome was 90-day stroke incidence. Results: During the 4-year study period, hospitals significantly increased statin use (adjusted odds ratio [aOR] per 1-year increase, 1.24 [95% CI, 1.17–1.32]; P<0.001), whereas neither hypertension control (P=0.44) nor antithrombotic use (P=0.82) improved over time. Hospitals that admitted a higher proportion of TIA patients versus emergency department discharge had significantly greater use of statins (aOR per 10-percentage point increase in the proportion of TIA patients admitted, 1.09 [1.03–1.16]; P=0.003) and antithrombotics (aOR per 10-percentage point increase in TIA patients admitted, 1.14 [1.06–1.23]; P<0.001). Hospitals with higher emergency physician staffing and lower TIA patient volume had greater use of antithrombotics (aOR per 1 full-time physician increase, 1.05 [1.01–1.08]; P=0.008 and aOR per 10-patient decrease in volume, 1.09 [1.01–1.16]; P=0.02). Higher emergency physician staffing was associated with lower 90-day stroke incidence (aOR per 1 full-time physician increase, 0.96 [0.92–0.99]; P=0.02) but other hospital factors were not. Conclusions: Hospitals admitting higher percentages of TIA patients and having higher emergency physician staffing have greater performance on select guideline-concordant process measures for TIA. Higher emergency physician staffing was associated with improved outcomes 90 days after TIA.Item Impact of new-onset versus pre-existing atrial fibrillation on outcomes after transcatheter aortic valve replacement/implantation(Elsevier, 2022-01-17) Nso, Nso; Emmanuel, Kelechi; Nassar, Mahmoud; Bhangal, Rubal; Enoru, Sostanie; Iluyomade, Adedapo; Marmur, Jonathan D.; Ilonze, Onyedika J.; Thambidorai, Senthil; Ayinde, Hakeem; Medicine, School of MedicinePatients with aortic stenosis who undergo transcatheter aortic valve replacement/transcatheter aortic valve implantation (TAVR/TAVI) experience a high incidence of pre-existing atrial fibrillation (pre-AF) and new-onset atrial fibrillation (NOAF) post-operatively. This systematic review and meta-analysis aimed to update current evidence concerning the incidence of 30-day mortality, stroke, acute kidney injury (AKI), length of stay (LOS), and early/late bleeding in patients with NOAF or pre-AF who undergo TAVR/TAVI. PubMed, Google Scholar, JSTOR, Cochrane Library, and Web of Science were searched for studies published between January 2012 and December 2020 reporting the association between NOAF/pre-AF and clinical complications after TAVR/TAVI. A total of 15 studies including 158,220 adult patients with TAVI/TAVR and NOAF or pre-AF were identified. Compared to patients in sinus rhythm, patients who developed NOAF had a higher risk of 30-day mortality, AKI, early bleeding events, extended LOS, and stroke after TAVR/TAVI (odds ratio [OR]: 3.18 [95% confidence interval [CI] 1.58, 6.40]) (OR: 3.83 [95% CI 1.18, 12.42]) (OR: 1.70 [95% CI 1.05, 2.74]) (OR: 13.96 [95% CI, 6.41, 30.40]) (OR: 2.51 [95% CI 1.59, 3.97], respectively). Compared to patients in sinus rhythm, patients with pre-AF had a higher risk of AKI and early bleeding episodes after TAVR/TAVI (OR: 2.43 [95% CI 1.10, 5.35]) (OR: 17.41 [95% CI 6.49, 46.68], respectively). Atrial fibrillation is associated with a higher risk of all primary and secondary outcomes. Specifically, NOAF but not pre-AF is associated with a higher risk of 30-day mortality, stroke, and extended LOS after TAVR/TAVI.Item Risk Factors for Unplanned Higher-Level Re-Amputation and Mortality after Lower Extremity Amputation in Chronic Limb-Threatening Ischemia(MDPI, 2024-07-10) Guerra, Andres; Guo, Michelle; Boyd, Riley M.; Zakharevich, Marina; Hoel, Andrew W.; Vavra, Ashley K.; Chung, Jeanette W.; Ho, Karen J.; Surgery, School of MedicineBackground: The factors associated with unplanned higher-level re-amputation (UHRA) and one-year mortality among patients with chronic limb-threatening ischemia (CLTI) after lower extremity amputation are poorly understood. Methods: This was a single-center retrospective study of patients who underwent amputations for CLTI between 2014 and 2017. Unadjusted bivariate analyses and adjusted odds ratios (AOR) from logistic regression models were used to assess associations between pre-amputation risk factors and outcomes (UHRA and one-year mortality). Results: We obtained data on 203 amputations from 182 patients (median age 65 years [interquartile range (IQR) 57, 75]; 70.7% males), including 118 (58.1%) toe, 20 (9.9%) transmetatarsal (TMA), 37 (18.2%) below-knee (BKA), and 28 (13.8%) amputations at or above the knee. Median follow-up was 285 days (IQR 62, 1348). Thirty-six limbs (17.7%) had a UHRA, and the majority of these (72.2%) were following index forefoot amputations. Risk factors for UHRA included non-ambulatory status (AOR 6.74, 95% confidence interval (CI) 1.74–26.18; p < 0.10) and toe pressure < 30 mm Hg (AOR 4.89, 95% CI 1.52–15.78; p < 0.01). One-year mortality was 17.2% (n = 32), and risk factors included coronary artery disease (AOR 3.93, 95% CI 1.56–9.87; p < 0.05), congestive heart failure (AOR 4.90, 95% CI 1.96–12.29; p = 0.001), end-stage renal disease (AOR 7.54, 95% CI 3.10–18.34; p < 0.001), and non-independent ambulation (AOR 4.31, 95% CI 1.20–15.49; p = 0.03). Male sex was associated with a reduced odds of death at 1 year (AOR 0.37, 95% CI 0.15–0.89; p < 0.05). UHRA was not associated with one-year mortality. Conclusions: Rates of UHRA after toe amputations and TMA are high despite revascularization and one-year mortality is high among patients with CLTI requiring amputation.
