ClinicalTrials.gov Identifier: NCT01714596

Brief Summary:

The goal of this study is to evaluate the effect of treatment of post-op wound infection in long bones after fracture fixation or joint fusion and either: (Group 1) operative debridement and PO antibiotic treatment for 6 weeks; or (Group 2) operative debridement and IV antibiotics for 6 weeks.

Primary Hypothesis 1: The rate of study injury related surgical interventions by one year in Group 1 will be non-inferior to the rate in Group 2.

Secondary Hypothesis 1: The rate of treatment failure by one year in Group 1 will be non-inferior to the rate in Group 2. Treatment failure is defined as wound problems that require surgery >2 weeks after initial debridement, infection recurrence, infection with a new pathogen, joint erosion, implant failure, medical problems related to the treatment administration which necessitates a switch from one arm to the other.

Secondary Hypothesis 2: The rate of re-hospitalization for complications, infection, non-union and amputation by one year in Group 1 will be non-inferior to the rate in Group 2.

Secondary Hypothesis 3: Following discharge for treatment of infection, per patient treatment costs at 1 year will be lower in Group 1 than in Group 2.

Secondary Hypothesis 4: Adherence in Group 1 will be non-inferior to adherence in Group 2.

Secondary Hypothesis 5: Patient satisfaction with treatment in Group 1 will be non-inferior to adherence in Group 2.

Specific Aim 2: To build and validate a risk prediction model for failure of treatment of early post-op wound infections after fixation of fractures and joint fusions.

Arm Intervention/treatment
Active Comparator: Oral Antibiotic
Oral Antibiotic Arm; Participants assigned to this group will receive oral antibiotics as prescribed by their treating physician.
Other: PO versus IV antibiotics Route of administration evaluation
This is a study of oral (per os, (PO)) antibiotic therapy versus intravenous (IV) antibiotics in the treatment of acute infection after fixation of fractures and joint fusions. This is not a study of an experimental drug but a study of route of administration of standard use antibiotics. Antibiotic regimen options decision will be made by the Study Surgeon at each site in consult with local Infectious Disease experts based on local standard practices and bacterial susceptibilities.
Other Name: based on local practices and bacterial susceptibilities

Active Comparator: IV Antibiotic
Participants assigned to this group will receive intravenous (IV) antibiotics as prescribed by their treating physician.
Other: PO versus IV antibiotics Route of administration evaluation
This is a study of oral (per os, (PO)) antibiotic therapy versus intravenous (IV) antibiotics in the treatment of acute infection after fixation of fractures and joint fusions. This is not a study of an experimental drug but a study of route of administration of standard use antibiotics.

Primary Outcome Measures :
  1. Study injury related surgical interventions by 1 year [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. Treatment Failure by 1 year [ Time Frame: 1 year ]
    Treatment failure is defined as wound problems that require surgery >2 weeks after initial debridement, infection recurrence, infection with a new pathogen, joint erosion, implant failure, medical problems related to the treatment administration which necessitates a switch from one arm to the other.

  2. Re-hospitalizations by 1 year [ Time Frame: 1 year ]
    Re-hospitalization for complications, such as infection, non-union and amputation

  3. Healthcare costs [ Time Frame: 1 year ]
    Cost of PO versus IV medications include medical record and bill abstracted costs associated with outpatient clinic visits, home health visits, medication, subsequent hospital readmission, and other types of medical care as identified over the course of the study.

  4. Medication Adherence [ Time Frame: 1 year ]

    Patient adherence to PO and IV medications

    Patient adherence with PO antibiotics will be monitored through wireless-enabled microchip monitors embedded in pill bottles by the Medication Event Monitoring System (MEMS) and weekly adherence questionnaire.


  5. Satisfaction with treatment [ Time Frame: 1 year ]

    Patient satisfaction with treatment measured by Short Form Patient Satisfaction Questionnaire (PSQ-18)

    The PSQ-18 measures 6 domains: technical quality, interpersonal manner, communication, financial aspects of care, time spent with doctor, and accessibility. A score of 0.8 or higher in each domain correlates with improved satisfaction.

Criteria

Inclusion Criteria:

  2. Patients undergoing fusion of any bone at or proximal to and including the subtalar joint or radial carpal joint, (excluding the spine) that develop a post op wound infection at any time.
  3. Patients diagnosed with a wound infection of the study injury, defined as patients with at least one of the following:

    1. Deep culture positive after operative debridement.
    2. Cultures positive in thio only after operative debridement.
    3. Negative culture after operative debridement if wound infection meets the Center for Disease control and Prevention (CDC) criteria.
