AbstractStaphylococcus aureus bacteraemia (SAB) is a common and severe disease. In 2012, a structured bedside consultation (SBC) was introduced at Rijnstate Hospital. We analysed the effect of this SBC on the overall survival of patients with SAB and the effect on the diagnostic workup. We performed a retrospective cohort study, including all patients over 18 years with SAB from 2009 until 2017. The cases preceding versus those after implementation of SBC in 2012 were compared. In total, 613 episodes of SAB were analysed: 234 cases before and 379 cases since SBC. In 484 patients at risk for a complicated course, there was no significant difference in the 30-day survival (77 versus 82%, p = 0.18); however, an increase in 365-day survival was seen (56 versus 64%, p = 0.05). Overall, more patients received adequate therapy, both in the first 2 weeks (67.8 versus 86.7%, p < 0.001), as in complicated SAB (70.5 versus 93.2%, p < 0.001). In 21% of patients with transoesophageal echocardiogram (TEE) following a negative or inconclusive TTE, endocarditis was diagnosed. In patients at risk for complicated SAB, the PET scan revealed a metastatic infection which was not clinically suspected in 65% of positive PET scans. Structured bedside consultation is associated with a better 365-day survival in patients at risk for complicated SAB. Moreover, the additional value of TEE and the PET scan was shown. We strongly advise compliance to SBC in all patients at risk for complicated SAB and the use of both TEE and PET scans in these patients. Even in uncomplicated SAB, TEE or PET scan can reveal metastatic infections.
