Measuring compliance with surgical antibiotic protocols: an intervention

Abstract

PurposeThe purpose of the paper is to measure compliance with agreed protocols for prophylactic antibiotics for five elective procedures: transurethral resection of the prostate, cholecystectomy, hysterectomy, joint arthroplasty and herniorrhaphy in two teaching hospitals.Design/methodology/approachCompliance was measured during the pre and post intervention periods by reviewing medical records.FindingsOverall, compliance improved by 18 per cent (95 per cent CI: 12 per cent, 23 per cent) with greater improvements for transurethral resection of the prostate and hysterectomy, increasing by 27 per cent (95 per cent CI: 14 per cent, 40 per cent) and 24 per cent (95 per cent CI: 16 per cent, 32 per cent) respectively. Compliance remained low for cholecystectomy (17 per cent) and hysterectomy (25 per cent). Overall, the proportion of patients not receiving any prophylaxis where its use was indicated, declined by 6 per cent (95 per cent CI: 1 per cent, 11 per cent) from 23 per cent. The use of additional anti‐microbials that were not recommended in the protocol was high for joint arthroplasty 65 per cent and hysterectomy 71 per cent, but overall this practice declined by 8 per cent (95 per cent CI: 3 per cent, 14 per cent). Costs were reduced from $11.72 to $10.53 per patient between the pre and post intervention groups, while a complete adoption of the protocols could reduce costs by 70 per cent to $3.40. There were large variations in correct dosages and timing of antibiotics between procedural groups.Practical implicationsAlthough compliance improved there were large differences between the specialties. The adoption of preventive strategies is fundamental to providing safe patient care. The use of inappropriate antimicrobials is also an important patient safety issue that contributes to antibiotic resistance and is associated with increased costs. Introducing change in health organizations is difficult and the factors influencing successful change strategies require further study.Originality/valueThe paper measures and improves compliance with agreed protocols in health care intervention procedures.
