Lower urine sodium predicts longer length of stay in acute heart failure patients: Insights from the ROSE AHF trial.

ABSTRACT:

Background

In patients hospitalized with acute heart failure (AHF), low urine sodium concentration (U_Na ) after diuretic treatment may identify patients at risk for longer length of stay (LOS) and adverse events. We investigated the prognostic significance of 24-hour cumulative postdiuretic urine sodium concentration in a multicenter clinical trial population.

Methods

The Renal Optimization Strategies Evaluation AHF (ROSE AHF) trial randomized 360 patients with AHF and renal dysfunction receiving intravenous diuretic to dopamine, nesiritide, or placebo. Sodium concentration was measured in cumulative urine sample collected during the first 24 hours after randomization in 298 patients. Based on prior studies, lower U_Na was defined as ≤60 mmol/L.

Results

Lower U_Na was present in 142 (48%) patients, who had longer LOS (7 days vs 5 days, P < .001) and less 72-hour weight loss (5.7 lb vs 9.0 lb, P < .001). These associations persisted after controlling for baseline estimated glomerular filtration rate and outpatient furosemide dose. Lower U_Na did not modify the null effects of dopamine or nesiritide on clinical outcomes. Results were similar for spot rather than cumulative 24-hour U_Na concentration.

Conclusion

In patients hospitalized for AHF and renal dysfunction, U_Na ≤ 60 mmol/L during the first 24 hours of diuresis identifies patients at risk for prolonged hospitalization but does not provide an indication for adjunctive dopamine or nesiritide.

Project description:ImportanceMore than 80% of patients who present to the emergency department (ED) with acute heart failure (AHF) are hospitalized. With more than 1 million annual hospitalizations for AHF in the US, safe and effective alternatives are needed. Care for AHF in short-stay units (SSUs) may be safe and more efficient than hospitalization, especially for lower-risk patients, but randomized clinical trial data are lacking.ObjectiveTo compare the effectiveness of SSU care vs hospitalization in lower-risk patients with AHF.Design, setting, and participantsThis multicenter randomized clinical trial randomly assigned low-risk patients with AHF 1:1 to SSU or hospital admission from the ED. Patients received follow-up at 30 and 90 days post discharge. The study began December 6, 2017, and was completed on July 22, 2021. The data were analyzed between March 27, 2020, and November 11, 2023.InterventionRandomized post-ED disposition to less than 24 hours of SSU care vs hospitalization.Main outcomes and measuresThe study was designed to detect at least 1-day superiority for a primary outcome of days alive and out of hospital (DAOOH) at 30-day follow-up for 534 participants, with an allowance of 10% participant attrition. Due to the COVID-19 pandemic, enrollment was truncated at 194 participants. Before unmasking, the primary outcome was changed from DAOOH to an outcome with adequate statistical power: quality of life as measured by the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12). The KCCQ-12 scores range from 0 to 100, with higher scores indicating better quality of life.ResultsOf the 193 patients enrolled (1 was found ineligible after randomization), the mean (SD) age was 64.8 (14.8) years, 79 (40.9%) were women, and 114 (59.1%) were men. Baseline characteristics were balanced between arms. The mean (SD) KCCQ-12 summary score between the SSU and hospitalization arms at 30 days was 51.3 (25.7) vs 45.8 (23.8) points, respectively (P = .19). Participants in the SSU arm had 1.6 more DAOOH at 30-day follow-up than those in the hospitalization arm (median [IQR], 26.9 [24.4-28.8] vs 25.4 [22.0-27.7] days; P = .02). Adverse events were uncommon and similar in both arms.Conclusions and relevanceThe findings show that the SSU strategy was no different than hospitalization with regard to KCCQ-12 score, superior for more DAOOH, and safe for lower-risk patients with AHF. These findings of lower health care utilization with the SSU strategy need to be definitively tested in an adequately powered study.Trial registrationClinicalTrials.gov Identifier: NCT03302910.

Project description:BackgroundOlder adults make up 33% of all trauma admissions in Australia despite comprising 17% of the population with rates rising faster for older age groups compared to any other age group. A high proportion of older adults admitted to hospital following trauma are frail and have increased rates of hospital acquired complications, resulting in poorer outcomes as well as increased resource utilisation and cost to the healthcare system. Length of Stay (LOS) is an important outcome for hospitals, contributing to resource utilisation and patient flow. This study aimed to determine factors associated with the primary outcome of LOS in older persons admitted with trauma at a major trauma centre as targets for improvement.MethodsEthics approval was obtained to collect data on all adult trauma admissions ≥ 1 day in patients aged 65 years and over. Patients were included in the Trauma in older persons (TOPS) database if they otherwise met criteria for the pre-existing trauma registry maintained by the hospital's trauma service. Admissions between January 2022 and January 2023 were included. Univariable negative binomial regression identified variables associated with LOS with p-values ≤ 0.1 which were then included in a multivariable regression model. Significance was taken as p-value ≤ 0.05.Results1250 admissions ≥ 1 day and alive at discharge were included in the primary analysis. The median LOS was 7 (4-13) days. In the multivariable model, delirium (Incidence Rate Ratio (IRR) = 1.41, 95%CI = 1.25-1.59), inpatient fall (IRR = 1.46, 95%CI = 1.15-1.86), pneumonia (IRR = 1.28, 95%CI = 1.08-1.53), thromboembolism (IRR = 1.43, 95%CI = 1.05-1.96), blood transfusion (IRR = 1.34, 95%CI = 1.17-1.53) and unplanned intensive care admission (IRR = 1.52, 95%CI = 1.08-2.14) were all associated with increased LOS. Low fall mechanism was high risk for longer LOS (IRR = 1.26, 95%CI = 1.11-1.43).ConclusionsAfter controlling for available factors, inpatient complications and patients admitted following low falls were identified as high risk for increased LOS and may represent areas for targeted quality improvement for older adults admitted following trauma.

Project description:IntroductionVitamin D deficiency is common in spinal surgery and critical care. Hypovitaminosis D may impact on outcomes in cranial neurosurgical care and play roles in underlying disease processes.MethodsA prospective observational cohort study was performed. All emergency cranial neurosurgical ward admissions from 1st January to 10th May 2017 were screened for inclusion (n = 406). Patients already receiving vitamin D supplementation, spinal patients and elective admissions were excluded. Admission vitamin D levels were checked for all remaining patients (n = 95). Patients with vitamin D <30 nmol/L were defined as "deficient" and those 30-50 nmol/L as "inadequate." All patients with levels <50 nmol/L were replaced, as per local guidelines. Descriptive analyses of the cohorts were undertaken, with multivariate regression used to assess the effect of vitamin D on length of stay, inpatient morbidity and mortality.ResultsThe median age of participants was 61 years (n = 95; 57% male, 43% female). The median vitamin D level was 23 nmol/L (deficient). 84% (n = 80) of patients had low vitamin D levels, with 61% (n = 58) classed as deficient (<30 nmol/L). Vitamin D deficiency rates were similar in those aged below 65 years (86%; n = 38/44) and those above 65 years (82%; n = 42/51). Deficient vitamin D level was associated with longer hospital stay (P = .03), and this relationship persisted after adjusting for potential confounders such as age, sex and preadmission Charlson co-morbidity index. No statistically significant association was seen with vitamin D status and inpatient morbidity or mortality.ConclusionsVitamin D deficiency is common in cranial neurosurgical patients, even in predefined low-risk groups (age <65). Lower vitamin D level was associated with longer length of stay. This study supports the need for: (a) further investigation into the roles of vitamin D in neurosurgical pathologies and management and (b) an appropriately powered, randomised investigation into the impact of vitamin D status upon neurosurgical diagnoses and complications.
