Background Aims Materials and Methods Results Conclusions Vaginal swab microbiological testing is commonly performed as routine clinical management for various obstetric and gynaecological presentations. The clinical utility and cost‐effectiveness of vaginal swab microscopy, culture and susceptibilities (MCS) in altering empirical management is ill‐defined.To describe the clinical use of vaginal swabs in a tertiary women's hospital emergency department (ED), measure the impact of vaginal swabs on altering empirical clinical management, and to determine the economic cost of vaginal swab MCS.Retrospective case‐series of vaginal swabs collected at a single, tertiary women's ED between January 2021 and July 2021. Symptomatology, clinical diagnosis, test results, and pre‐swab and post‐swab clinical management were determined upon medical record review. Economic costs of vaginal swab MCS were retrospectively determined via internal accounting records, permitting unit‐level activity‐based costing.A total of 660 vaginal swabs from 584 clinical episodes were included. Vulvovaginitis was the most common indication for swab collection (34.5%, 167 samples). Altered empirical management was observed in 9.8% of all swabs (95% CI 7.4–12.2%), with marked variability between clinical indications. Antimicrobial initiation was the most common alteration in management (8.9%, 95% CI 8.7–9.1%). The estimated cost of vaginal swab MCS was $29.71 AUD; labour, consumables and disposal costs accounted for 69.3, 29.8 and 0.9%, respectively.The impact of vaginal swab MCS on empirical clinical management is context‐specific and variable. The majority of swabs performed do not impact upon empirical management. Antimicrobial initiation is appreciably more common than antimicrobial cessation with vaginal swab results.
