Liver Cancer, Adult
Conditions
Brief summary
This study focuses on the early identification and precision prevention of acute kidney injury (AKI) following interventional therapy in patients with liver cancer. A prospective, phased mixed-methods research design will be adopted. In the first phase, a prospective cohort study will be conducted to systematically collect clinical and nursing-related data. A Super Learner ensemble algorithm will be employed to develop and validate an AKI risk prediction model, enabling precise risk stratification of patients. In the second phase, a prospective randomized controlled trial will be implemented. Guided by the Health Belief Model (HBM), a risk-stratified proactive nursing intervention will be delivered, and its effectiveness will be compared with that of routine nursing care in reducing the incidence of AKI, improving adherence to hydration protocols, optimizing the management of nephrotoxic medications, and enhancing patients' self-management capabilities. By integrating intelligent risk prediction with proactive nursing intervention strategies, this study aims to establish a reproducible and scalable precision prevention and management model for AKI in liver cancer patients undergoing interventional therapy. The findings are expected to provide scientific evidence for early AKI warning and proactive nursing practice, thereby promoting the precision, intelligence, and standardization of oncologic interventional nursing care.
Interventions
BEHAVIORALRisk-stratified active nursing intervention group
The intervention employed in this study is a proactive nursing intervention package based on AKI risk stratification and the Health Belief Model (HBM). Prior to interventional therapy, participants are assessed using the AKI risk prediction model and categorized into low-, moderate-, and high-risk groups. Stratified and weighted interventions are then implemented according to the assigned risk level. The intervention is delivered at five critical time points: one day before the procedure, postoperative day 1, postoperative day 2, postoperative day 3, and after hospital discharge. Intervention strategies are designed around the six core constructs of the Health Belief Model, including perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. Specific measures encompass medication management, fluid therapy, renal function monitoring, patient and family education, behavioral support, and follow-up management

Inclusion criteria
* Completed eligibility screening in Phase I of the study * Completed AKI risk assessment using the established prediction model * Classified by the model as at risk for AKI (moderate- or high-risk patients prioritized; low-risk patients included only for exploratory/observational analysis) * Conscious and able to communicate effectively * Able to understand and comply with nursing interventions * Expected hospital stay of at least 3 days * Available for postoperative follow-up * Provided written informed consent jointly with a primary caregiver
Exclusion criteria
* Development of AKI within 24 hours after interventional therapy according to KDIGO criteria * Severe psychiatric disorders, cognitive impairment, or communication barriers preventing participation in HBM-based assessment or intervention * Requirement for postoperative ICU admission and continuous life-support therapy * Mandatory use of nephrotoxic medications that cannot be discontinued, substituted, or adjusted during the study period * Participation in other clinical intervention studies that may affect renal function or nursing outcomes
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative acute kidney injury incidence | AKI was assessed within the first 7 days following interventional therapy | The primary outcome was the occurrence of postoperative acute kidney injury (AKI). AKI was assessed within the first 7 days following interventional therapy and defined according to the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines as the presence of any of the following: (1) an increase in serum creatinine of ≥0.3 mg/dL (≥26.5 μmol/L) within 48 hours; (2) an increase in serum creatinine to ≥1.5 times the baseline level, known or presumed to have occurred within the prior 7 days; or (3) a urine output of \<0.5 mL/kg/h for at least 6 hours. |
