Summary
Refeeding hypophosphatemia in critically ill elderly patients did not impact mortality or ICU stay. This condition, common in older adults with acute illness, showed similar outcomes whether present or absent.
Area of Science:
- Geriatric Medicine
- Critical Care Medicine
- Clinical Nutrition
Background:
- Refeeding syndrome involves metabolic and electrolyte changes after nutritional restoration.
- Elderly patients with acute/chronic illness often have malnutrition due to poor intake and catabolism.
- This study focuses on refeeding hypophosphatemia in critically ill elderly patients.
Purpose of the Study:
- To evaluate refeeding hypophosphatemia in the oldest old critically ill patients.
- To assess the consequences of refeeding hypophosphatemia on patient outcomes.
- To determine the incidence of refeeding hypophosphatemia in this high-risk population.
Main Methods:
- Retrospective cohort study design.
- Included patients aged 80 years or older admitted to the ICU.
- Grouped patients based on the occurrence of hypophosphatemia after 48 hours of feeding initiation.
Main Results:
- Median age was 87 years; 73% were female.
- Refeeding hypophosphatemia occurred in 30% of patients.
- No significant differences in ICU mortality, hospital mortality, severity scores, or comorbidities between groups.
Conclusions:
- Incidence of refeeding hypophosphatemia was consistent with previous studies, despite the high-risk cohort.
- Refeeding hypophosphatemia did not significantly affect mortality or ICU length of stay.
- Outcomes were similar for critically ill elderly patients with or without refeeding hypophosphatemia.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Acute Kidney Injury (AKI) results in an inability to maintain fluid, electrolyte, and acid-base balance. Effective nursing management is critical in improving patient outcomes and includes comprehensive patient assessment and targeted interventions.Comprehensive Patient AssessmentA detailed history collection is essential, focusing on any recent infections, nephrotoxic medication use, or chronic conditions such as hypertension and diabetes that may contribute to AKI.

01:11Renal Failure: Dose Adjustments
121
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
