BACKGROUND: To allow better allocation of staff and resources, rapid response teams attending to acutely deteriorating or aggressive patients with suspected or confirmed COVID‐19 infection were pre‐warned with the announcement of 'Code‐95' with calls. AIM: To assess healthcare worker (HCW) perspectives on pre‐warning rapid response calls (RRC) with ‘Code‐95’ in announcements when attending to deteriorating or aggressive patients with suspected/confirmed COVID‐19 infection. METHODS: Design: prospective cross‐sectional single‐centre survey of HCW over a 3‐week period. Setting: tertiary public hospital. Participants: HCW caring for deteriorating or aggressive patients. Main outcome measures: the primary outcome was to assess HCW perspectives in attending Code‐95 calls. Secondary outcomes were to identify any differences related to craft group, age, experience or presence of comorbidities. RESULTS: A total of 297 responses was analysed; 86.7% of HCW (n = 257) attending Code‐95 calls reported anxiety. Medical staff reported greater anxiety in comparison to nursing staff (93.8% vs 78.5%; P = 0.002). Efferent team reported higher anxiety in contrast to afferent team (92.6% vs 58.8%; P = 0.021). There was no significant difference in perceived anxiety based on age (≤40 vs >40 years of age), years of experience (≤5 vs >5 years), comorbidities or mental illness; 54% reported concerns about adequacy of infection‐control policies and personal protective equipment; 45% were worried about inadequate training for responding to Code‐95 calls. CONCLUSIONS: Most surveyed HCW supported Code‐95 announcements pre‐warning them of potential COVID‐19 exposure when attending a RRC. However, the majority of HCW reported anxiety when attending these calls. Medical and efferent team HCW perceived greater anxiety compared to nursing and afferent team HCW. The Code‐95 system to pre‐warn rapid response teams may be a useful addition to protecting HCW from infectious diseases, although broader implementation will require greater resourcing, training and support.
