简要总结
Research question: If adults with bone or joint infection have local antibiotic therapy, can they do without prolonged treatment with antibiotics by mouth (oral) or injection?
Adults with bone or joint infections are usually given long courses of oral antibiotics or into a vein (intravenous) following surgery. It is also safe to give antibiotics directly into the bone or joint at the time of surgery: this is called local antibiotic therapy. This study investigates whether using local antibiotic therapy would allow shorter courses of oral or intravenous antibiotics, in order to limit antibiotic resistance, side effects and cost.
This study compares short against long courses of oral or intravenous antibiotics for adults who have been given appropriate local antibiotic therapy to treat bone or joint infection. Patients who can take part will be randomly divided into two groups within 7 days of surgery. One group will stop oral or intravenous antibiotics, while the other group will continue for 4 weeks or more (standard treatment).
Adults with bone and joint infections who have already had surgery and local antibiotic therapy will be invited. Patients will not take part if they need intravenous antibiotics for another reason, or if their infection is caused by bacteria resistant to the antibiotic(s) used in their local antibiotic therapy.
Main measurement: how many patients' infections return within 12 months after surgery. This will be decided by a group of doctors who do not know what treatment the patient received.
Other important measurements: serious adverse events; side-effects; quality of life; cost of treatment.
Patients will be asked questions at their usual clinic visits, and will be given a questionnaire at the start of treatment and 1 year later.
详细描述
Using antibiotics wisely, only when and where they are really needed, is important to prevent superbugs emerging. At the moment, bone and joint infections are usually treated by a combination of surgery and antibiotics. Traditionally, treatment relies on several weeks of antibiotics as tablets or injections (systemic antibiotics), but these can sometimes cause problems.
It is now possible to administer local antibiotics at the time of surgery directly to the site of infection. This allows much higher levels of the antibiotic to be delivered, for days or weeks, following surgery. Therefore, this study will investigate whether local antibiotics with a shorter course of systemic antibiotics can treat bone and joint infections as effectively as local antibiotics with a prolonged course of systemic antibiotics (usual treatment). If so, it may be possible to reduce antibiotic side effects, help to prevent antibiotic resistant bacteria emerging and limit overall treatment costs.
Patients who agree to participate in this study will be allocated at random to two treatment strategies after surgery for bone and joint infection.
One group of patients will be treated with local antibiotics and a long course of systemic antibiotics, which is the usual treatment: this is the 'long group'.
The other group will be treated with local antibiotics and a short course of systemic antibiotics: this is the 'short group' whose treatment differs from the current usual treatment.

盲法说明
Ascertainment of the primary outcome (treatment failure) will be undertaken by an independent committee of specialists, using redacted participant clinical records, who will remain unaware of the treatment allocation of the participant, and who will ascertain treatment failure according to established objective criteria.

排除标准
- •Surgical exclusion criteria

- •Primary closure has not been achieved, or
- •Re-look surgery is planned
- •The index operation involved implant retention (e.g. DAIR)
- •Microbiological exclusion criteria
- •Any identified micro-organisms from operative specimens from the site of incident infection are fully resistant to the local antibiotic(s) administered at the site of infection
- •Medical exclusion criteria
- •Other infection necessitating additional systemic antibiotic treatment beyond 7 days after surgery, such as Staphylococcus aureus bacteraemia, psoas abscess, discitis or bacterial endocarditis
- •If the patient is in a clinical trial involving an Investigational Medicinal Product (IMP) related to infection
结局指标
主要结局
Definitive treatment failure (infection recurrence)
时间窗: 12 months from the time of surgery for bone or joint infection
Proportion of participants in each treatment group experiencing definitive treatment failure (infection recurrence), ascertained by an independent committee of experts unaware of the treatment allocation of the participant, according to established criteria.
次要结局
- Possible or probable treatment failure(12 months from the time of surgery for bone or joint infection)
- Serious Adverse Events(12 months from the time of surgery for bone or joint infection)
- Quality of life measured by EuroQol 5 Dimensions 5 Levels Score and EuroQol Visual Analogue Score(At baseline and 12 months from the time of surgery for bone or joint infection)
- Antibiotic side effects(This will be assessed at baseline (pre-randomisation, at <7 days of treatment), 6 weeks and 3 months from the time of surgery for bone or joint infection)
