Item Open Access Association of Severe Acute Kidney Injury with Mortality and Healthcare Utilization Following Isolated Traumatic Brain Injury.(Neurocritical care, 2021-01-13) Luu, David; Komisarow, Jordan; Mills, Brianna M; Vavilala, Monica S; Laskowitz, Daniel T; Mathew, Joseph; James, Michael L; Hernandez, Adrian; Sampson, John; Fuller, Matt; Ohnuma, Tetsu; Raghunathan, Karthik; Privratsky, Jamie; Bartz, Raquel; Krishnamoorthy, VijayBackground/objective
Traumatic brain injury (TBI) is a leading cause of morbidity, mortality, and disability in the USA. While cardiopulmonary dysfunction can result in poor outcomes following severe TBI, the impact of acute kidney injury (AKI) is poorly understood. We examined the association of severe AKI with hospital mortality and healthcare utilization following isolate severe TBI.Methods
We conducted a retrospective cohort study using the National Trauma Data Bank from 2007 to 2014. We identified a cohort of adult patients with isolated severe TBI and described the incidence of severe AKI, corresponding to Acute Kidney Injury Network stage 3 disease or greater. We examined the association of severe AKI with the primary outcome of hospital mortality using multivariable logistic regression models. In secondary analyses, we examined the association of severe AKI with dialysis catheter placement, tracheostomy and gastrostomy utilization, and hospital length of stay.Results
There were 37,851 patients who experienced isolated severe TBI during the study period. Among these patients, 787 (2.1%) experienced severe (Stage 3 or greater) AKI. In multivariable models, the development of severe AKI in the hospital was associated with in-hospital mortality (OR 2.03, 95% CI 1.64-2.52), need for tracheostomy (OR 2.10, 95% CI 1.52-2.89), PEG tube placement (OR 1.88, 95% CI 1.45-2.45), and increased hospital length of stay (p < 0.001).Conclusions
The overall incidence of severe AKI is relatively low (2.1%), but is associated with increased mortality and multiple markers of increased healthcare utilization following severe TBI.Item Open Access COVID-19 and Severe Rhabdomyolysis Causing Acute Kidney Injury and Life-Threatening Hyperkalemia in a Pediatric Patient: a Case Report.(SN comprehensive clinical medicine, 2023-01) Geeting, Danielle; Alibrahim, Omar; Patel, Mital; Kumar, Reeti; Mallory, PalenThough initially believed to primarily be a respiratory pathogen, the SARS-CoV-2 virus has manifested as a virus that has the potential to affect multiple organ systems causing a wide variety of disease and symptomatology. Children have been largely spared in comparison to adult morbidity and mortality; however, acute pediatric illness secondary to COVID-19 infection has become both more common and more serious. Here, we present a teenager with acute COVID-19 who presented to the hospital with profound weakness and oliguria and was discovered to have severe rhabdomyolysis causing life-threatening hyperkalemia and acute kidney injury. He required treatment with emergent renal replacement therapy in the intensive care unit. His initial CK was 584,886 U/L. Creatinine was 14.1 mg/dL and potassium was 9.9 mmol/L. He was successfully treated with CRRT and was discharged on hospital day 13 with normal kidney function on follow-up. Rhabdomyolysis and acute kidney injury are increasingly recognized as complications of acute SARS-CoV-2 infection and require vigilance given the potentially fatal complications and long-standing morbidity associated with these conditions.Item Open Access Elevated D-Dimer Is Associated with Multiple Clinical Outcomes in Hospitalized Covid-19 Patients: a Retrospective Cohort Study.(SN comprehensive clinical medicine, 2020-11-08) Wagner, Jason; Garcia-Rodriguez, Victor; Yu, Abraham; Dutra, Barbara; DuPont, Andrew; Cash, Brooks; Farooq, AhmadD-dimer is a prognostic marker for Covid-19 disease mortality and severity in hospitalized patients; however, little is known about the association between D-dimer and other clinical outcomes. The aim of this paper was to define a threshold of D-dimer to use in hospitalized patients with Covid-19 and to assess its utility in prognosticating in-hospital mortality, development of an acute kidney injury (AKI), and need for hemodialysis, vasopressors, or intubation. This is a single-center, retrospective, cohort review study of 100 predominantly minority patients (94%) hospitalized with Covid-19. The electronic medical record system was used to collect data. Receiver operating characteristics (ROC) and area under the curve (AUC) analysis were used to determine optimal thresholds of peak D-dimer, defined as the highest D-dimer obtained during admission that was clinically meaningful. Odds ratios were then used to assess the relationship between peak D-dimer thresholds and clinical outcomes. D-dimer > 2.1 μg/mL and > 2.48 μg/mL had > 90% sensitivity and > 50% specificity for predicting need for vasopressors (AUC 0.80) or intubation (AUC 0.83) and in-hospital mortality (AUC 0.89), respectively. Additionally, D-dimer > 4.86 μg/mL had a 100% sensitivity and 81% specificity for predicting the need for hemodialysis (AUC 0.92). Furthermore, peak D-dimer > 2.48 μg/mL was associated with in-hospital mortality (p < 0.001), development of an AKI (p = 0.002), and need for intubation (p < 0.001), hemodialysis (p < 0.001), and vasopressors (p < 0.001). Peak D-dimer > 2.48 μg/mL may be a useful threshold that is prognostic of multiple clinical outcomes in hospitalized patients with Covid-19.Item Open Access Hospital discharge communications during care transitions for patients with acute kidney injury: a cross-sectional study.(BMC Health Serv Res, 2016-08-30) Greer, Raquel C; Liu, Yang; Crews, Deidra C; Jaar, Bernard G; Rabb, Hamid; Boulware, L EbonyBACKGROUND: High quality hospital discharge communications about acute kidney injury (AKI) could facilitate continuity of care after hospital transitions and reduce patients' post-hospitalization health risks. METHODS: We characterized the presence and quality (10 elements) of written hospital discharge communications (physician discharge summaries and patient instructions) for patients hospitalized with AKI at a single institution in 2012 through medical record review. RESULTS: In 75 randomly selected hospitalized patients with AKI, fewer than half of physician discharge summaries and patient instructions documented the presence (n = 33, 44 % and n = 10, 13 %, respectively), cause (n = 32, 43 % and n = 1, 1 %, respectively), or course of AKI (n = 23, 31 %, discharge summary only) during hospitalization. Few provided recommendations for treatment and/or observation specific to AKI (n = 11, 15 and 6, 8 % respectively). In multivariable analyses, discharge communications containing information about AKI were most prevalent among patients with AKI Stage 3, followed by patients with Stage 2 and Stage 1 (adjusted percentages (AP) [95 % CI]: 84 % [39-98 %], 43 % [11-82 %], and 24 % [reference], respectively; p trend = 0.008). AKI discharge communications were also more prevalent among patients with known chronic kidney disease (CKD) versus those without (AP [95 % CI]: 92 % [51-99 %] versus 39 % [reference], respectively, p = 0.02) and among patients discharged from medical versus surgical services (AP [95 % CI]: 73 % [33-93 %] versus 23 % [reference], respectively, p = 0.01). Communications featured 4 median quality elements. Quality elements were greater in communications for patients with more severe AKI (Stage 3 (number of additional quality elements (β) [95 % CI]: 2.29 [0.87-3.72]), Stage 2 (β [95 % CI]: 0.62 [-0.65-1.90]) and Stage 1 (reference); p for trend = 0.002). CONCLUSIONS: Few hospital discharge communications in AKI patients described AKI or provided recommendations for AKI care. Improvements in the quality of hospital discharge communications to improve care transitions of patients with AKI are needed.Item Open Access The Model for End-Stage Liver Disease-Sodium Score at Admission Is Prognostic of Covid-19 Disease Severity.(SN comprehensive clinical medicine, 2020-09-28) Wagner, Jason; Garcia-Rodriguez, Victor; Yu, Abraham; Dutra, Barbara; Bhatt, Asmeen; Larson, Scott; Farooq, AhmadCovid-19 is a systemic viral respiratory illness that can cause gastrointestinal manifestations. There is evidence that Covid-19 can infect liver tissue and may cause transaminemia. A prognostic model is needed to aid clinicians in determining disease severity. The Model for End-Stage Liver Disease-Sodium (MELD-Na) score is a mortality assessment tool in liver transplant patients that has been found to be prognostic in other clinical situations. This study aimed to determine if the MELD-Na score was associated with disease severity in patients with Covid-19, as assessed by multiple clinical outcomes including death within 30 days of discharge and development of an acute kidney injury (AKI). This is a retrospective cohort study that analyzed patients admitted to a community academic hospital with the diagnosis of Covid-19. The 30-day MELD-Na score was found to be significantly higher in those who died (14.38 ± 6.92) relative to those who survived (9.68 ± 5.69; p = 0.03). Additionally, patients with a MELD-Na score greater than 10 were found to have higher risk of developing an AKI (odds ratio (OR) 3.31 (1.08, 10.17); p = 0.03), need for hemodialysis (OR 9.69 (1.74, 53.96); p = 0.007), require vasopressors (OR 4.55 (1.22, 16.99); p = 0.02), and have a longer hospital stay (OR 4.17 (1.05, 16.47); p = 0.03). The MELD-Na score may serve as a useful clinical scoring system for prognosis in patients admitted to the hospital with Covid-19.
