Does a longer course of antibiotics reduce the incidence of wound infections after amputation surgery?

A randomised control trial to determine whether a 5 day course of antibiotics is more clinically and cost effective than a 24 hour prophylactic course for the prevention of surgical site infection following lower limb amputation surgery - The Amputation Surgical Site Infection Trial (ASSIT)

Design outcomes

Primary

MeasureTime frame
Main Objective: Primary objective: to establish if a 5 day course of antibiotics is more clinically and cost effective than a 24 hour prophylactic course in preventing surgical site infection in patients undergoing lower limb amputation.; Secondary Objective: Secondary objectives: •The impact of different skin preparations on infection rates (alcoholic povidone vs alcoholic chlorhexidine) •Rate of re-intervention, and if present, type of re-intervention and level •Mortality •Satisfactory healing rates •Quality of life/utility: SF-12, EQ-5D, McGill Pain score •Mobility (Locomotor Capabilities Index - LCI) •Resource use (including length of stay, number of visits to general practitioners, hospital visits, and prescription of antibiotics). •Rate of C.Diff., MSSA, MRSA infections. ;Primary end point(s): Primary: Occurrence of a surgical site infection. Participants will be asked to complete the Health Protection Agency ‘Patient post discharge questionnaire.’; Timepoint(s) of evaluation of this end point: The questionnaire will be completed at day 7,14, 30 post surgery. On day 14 post surgery participants will undergo clinical review by a clinician blinded to group allocation and the patient post discharge questionnaire completed. Occurrence of a SSI will be defined as positive finding at any of the four follow ups.

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: Secondary end points will be measured at baseline, 7, 14, 30 days and months 3 and 12 post surgery.; Secondary end point(s): •The impact of different skin preparations on infection rates (alcoholic povidone vs alcoholic chlorhexidine) •Rate of re-intervention, and if present, type of re-intervention and level •Mortality •Satisfactory healing rates •Quality of life/utility: SF-12, EQ-5D, McGill Pain score •Mobility (Locomotor Capabilities Index - LCI) •Resource use (including length of stay, number of visits to general practitioners, hospital visits, and prescription of antibiotics). •Rate of C.Diff., MSSA, MRSA infections.
