Summary
This study shows that an online algorithm effectively guides once-daily or twice-daily intravenous antibiotic treatment for cellulitis at home. The once-daily regimen, while having similar effectiveness, significantly increased home-based treatment capacity.
Area of Science:
- Infectious Diseases
- Hospital Medicine
- Health Services Research
Background:
- Cellulitis is a common cause of emergency department visits and hospitalizations.
- Hospital-in-the-home programs offer an alternative for managing cellulitis.
- Current guidelines recommend once or twice-daily intravenous antibiotics, but real-world data is limited.
Purpose of the Study:
- To evaluate the safety and effectiveness of home-based cellulitis treatment using an online decision support algorithm.
- To compare once-daily versus twice-daily intravenous antibiotic regimens for uncomplicated cellulitis.
- To assess the impact of the online algorithm on treatment capacity and patient outcomes.
Main Methods:
- A prospective study of 301 patients with uncomplicated cellulitis eligible for home-based therapy over 12 months.
- Patients received either once-daily (cephazolin plus probenecid) or twice-daily (cephazolin alone) intravenous antibiotics guided by an online algorithm.
- Primary outcome was time to non-progression of cellulitis; length of stay and side-effects were also recorded.
Main Results:
- The mean time to non-progression was similar for once-daily (2.11 days) and twice-daily (2.13 days) regimens (P=0.92).
- The once-daily regimen was associated with a shorter mean length of hospital stay (6.55 vs 7.67 days, P=0.06).
- The once-daily strategy increased hospital-in-the-home treatment capacity by 52% and had slightly higher reported side-effects (15.5% vs 9.1%).
Conclusions:
- An online decision support algorithm effectively facilitates once or twice-daily treatment for uncomplicated cellulitis.
- Home-based cellulitis treatment guided by this algorithm enhances efficiency and capacity.
- This approach aligns treatment options with clinician and patient preferences, improving care delivery.

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
