Abstract

Objective: To synthesise the available evidence and estimate the comparative efficacy of control strategies to prevent total hip replacement (THR)-related surgical site infections (SSIs) using a mixed treatment comparison.
Design: Systematic review and mixed treatment comparison.
Setting: Hospital and other healthcare settings.
Participants: Patients undergoing THR.
Primary and secondary outcome measures: The number of THR-related SSIs occurring following the surgical operation.
Results: 12 studies involving 123 788 THRs and 9 infection control strategies were identified. The strategy of ‘systemic antibiotics+antibiotic-impregnated cement +conventional ventilation’ significantly reduced the risk of THR-related SSI compared with the referent strategy (no systemic antibiotics+plain cement+conventional ventilation), OR 0.13 (95% credible interval (CrI) 0.03–0.35), and had the highest probability (47–64%) and
highest median rank of being the most effective strategy. There was some evidence to suggest that ‘systemic antibiotics+antibiotic-impregnated cement +laminar airflow’ could potentially increase infection risk compared with ‘systemic antibiotics+antibiotic impregnated cement+conventional ventilation’, 1.96 (95% CrI 0.52–5.37). There was no high-quality evidence that antibiotic-impregnated cement without
systemic antibiotic prophylaxis was effective in reducing infection compared with plain cement with systemic antibiotics, 1.28 (95% CrI 0.38–3.38). Conclusions: We found no convincing evidence in favour of the use of laminar airflow over conventional ventilation for prevention of THR-related SSIs, yet laminar airflow is costly and widely used. Antibiotic-impregnated cement without systemic antibiotics may not be effective
in reducing THR-related SSIs. The combination with the highest confidence for reducing SSIs was ‘systemic antibiotics+antibiotic-impregnated cement+conventional ventilation’. Our evidence synthesis underscores the need to review current guidelines based on the available
evidence, and to conduct further high-quality doubleblind randomised controlled trials to better inform the current clinical guidelines and practice for prevention of THR-related SSIs.
