Oral antibiotics as effective as IV therapy in bone and joint infections, finds study

In their analysis of 328 patients (145 pre- and 183 post-implementation), the researchers noted the following key facts.

• 66.1% of patients were switched to a suitable oral antibiotic regimen post-implementation.
• The rate of treatment failure was more common post-implementation (18.6%) compared with pre-implementation (13.6%), but Kaplan-Meier analysis of infection-free survival at 12 months did not demonstrate any statistical difference between the two groups (P = .154).
• Subgroup analysis showed that in the post-implementation period, treatment failure was more common in patients who required IV antibiotics due to lack of suitable options (IV, 26.7% vs oral, 14.3%).
• ADRs requiring close monitoring or change of treatment were more common post-implementation (37.1% vs 21% pre-implementation), but ADR-related hospital readmissions were similar in both groups (2.2% vs 2.1%).
• The post-implementation group showed a reduction in 4 days in the median LOS and a median cost reduction of £ 2,764.28 (US $3,558) per patient.

Findings further highlighted that this was due to the use of oral antibiotics, the need to insert a vascular access device could be completely avoided. This improved patient experience and reduced the risk of healthcare-associated infections. This also represented a financial benefit to the wider healthcare economy.

"These findings provide a useful guide for hospitals implementing the results of the OVIVA trial. Larger multicenter studies are required to better understand the differences in antibiotic regimens in varying patient groups and against specific pathogens." concluded the research team.
