Abstract
BACKGROUND: The current standard of care for tetanus prophylaxis management in patients with open wounds likely results in overtreatment and unnecessary costs. Point-of-care immunochromatographic tests, known as Tetanus Quick Sticks (TQS), have been developed to qualitatively measure tetanus immunoglobulin levels. Multiple studies advocate their use in EDs. We aim to evaluate the diagnostic accuracy and cost-effectiveness of TQS to assess their relevance in frontline emergency care. METHODS: A systematic review was undertaken following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search was conducted in MEDLINE, Embase, Global Health, The Health Management Information Consortium and The Cochrane Library. Studies were eligible if sensitivity, specificity or cost-efficacy of TQS was reported. At least two authors independently assessed and extracted data from each study. A meta-analysis was conducted to evaluate summary sensitivity and specificity estimates for TQS. RESULTS: 12 studies were suitable for inclusion (n=1 662 865 participants): 1 modelling and 11 prospective observational cohort studies. Eight studies assessed diagnostic accuracy; the summary estimate for sensitivity was 90% (95% CI, 89% to 90%) with specificity 97% (95% CI, 95% to 100%). Six studies investigated cost-efficacy, reporting lower healthcare costs when using TQS instead of the current method of vaccination history, due to a decrease in unnecessary tetanus vaccine and immunoglobulin administration. Based on the current NHS supply chain data, TQS use could save £173.05 per tetanus-prone patient. CONCLUSION: TQS could confer the greatest cost savings if used in combination with vaccination history in patients with tetanus-prone wounds. A quality assurance process is recommended prior to implementation of TQS in EDs.
