Factors Predicting Acute Kidney Injury among Patients with Sepsis at Emergency Department
Main Article Content
Abstract
Purpose: To examine the predictive power of health literacy, perceived severity of disease, family support, prehospital time, and the incidence of acute kidney injury among patients with sepsis in the emergency department.
Design: A cross-sectional predictive research design.
Methods: A total of 151 participants, both male and female, aged 18 years or older, and diagnosed with sepsis, were selected using convenience sampling from the Emergency Department of a tertiary hospital located in Bangkok. Data were collected using Mini-Cognitive Assessment Instrument, general information form, Acute Kidney Injury Assessment form, Health Literacy in Emergency Illness Scale, the Perceived Severity of Disease Scale, and the Chinese Family Support Scale. Data analysis was performed using descriptive statistics and logistic regression.
Main findings: Health literacy, perceived severity of disease, family support, and prehospital time jointly predicted acute kidney injury (AKI) in patients with sepsis by explaining 45% of its variance (Nagelkerke R² = .45). Participants with moderate and adequate health literacy had a reduced likelihood of developing AKI by 84% (OR = .16, 95%CI [.05, .52], p = .002) and 95% (OR = .05, 95%CI [.01, .17], p < .001), respectively. Participants with high perceived severity of disease had a 62% lower likelihood of developing AKI (OR = .38, 95%CI [.15, .99], p = .05). In contrast, participants with prehospital times exceeding 72 and 120 hours after symptom recognition had approximately fourfold increased odds of developing AKI (OR = 4.09, 95%CI [1.12, 14.88], p = .033 and OR = 3.92, 95%CI [1.27, 12.15], p = .02, respectively). Although family support was associated with AKI (c2 = 10.07, p = .007), it did not predict AKI when the other study variables were controlled.
Conclusion and recommendations: Nurses and healthcare professionals should apply the findings of this study to the planning and delivery of care for patients with sepsis, focusing on the enhancement of health literacy, perceived severity of disease, and family involvement at the early stage of sepsis. Such interventions can promote timely healthcare-seeking behavior, reduce disease severity, and prevent the development of acute kidney injury.
