Objectives: Hospital at home (HAH) replaces acute inpatient hospital care for selected patients by providing care in their homes. We sought to describe the characteristics, management, and complications of patients with osteoarticular infections (OAIs) treated in an HAH program and its economic impact.
Methods: We conducted a retrospective observational study evaluating an HAH program in a pediatric hospital in Spain, describing the characteristics of patients with confirmed OAIs requiring intravenous antibiotic therapy admitted to this program between January 2019 and December 2022. The program operates as a virtual ward with possible daily visits by physicians and nurses and 24/7 telephone contact.
Results: A total of 88 patients (median age, 4.1 years; interquartile range [IQR], 1.7-10.6) with OIAs were admitted to the HAH program. Osteomyelitis (57%) and septic arthritis (29%) were the most frequent infections. Cefuroxime (42%) and cefazolin (39%) were the most frequently prescribed antibiotics. Caregiver self-administration was performed in 99%, allowing multiple daily doses of antimicrobial therapy, 80% by peripheral line. Thirteen patients (15%) had drug-related adverse events, only 3 requiring drug modification. Two patients (2%) were readmitted during HAH, and 1 was readmitted within 30 days of HAH discharge. The median HAH stay was 7 days (IQR, 4-8.75). For osteomyelitis, hospital days lowered from 8.5 days (IQR, 4.5-12) to 4 days (IQR, 3-7) after HAH implementation (P = .005) with 68% per-patient estimated cost savings.
Conclusions: HAH treatment of OAIs is effective and cost-efficient. Patient support by medical and nursing staff, adequate family training, and regular communication are essential to ensure safe home admission.
