The cost effectiveness of reusable vs. single-use flexible bronchoscopy in the peri-operative setting has yet to be determined. We therefore aimed to determine this and hypothesised that single-use flexible bronchoscopes are cost effective compared with reusable flexible bronchoscopes. We conducted a systematic review of the literature, seeking all reports of cross-contamination or infection following reusable bronchoscope use in any clinical setting. ⋯ The cost per use of a single-use flexible bronchoscope was £220 sterling. The cost effectiveness analysis demonstrated that reusable flexible bronchoscopes have a cost per patient use of £511 sterling due to the costs of treatment of infection. The findings from this study suggest benefits from the use of single-use flexible bronchoscopes in terms of cost effectiveness, cross-contamination and resource utilisation.

Observational Study
Red blood cell transfusion in surgery: an observational study of the trends in the USA from 2011 to 2016.
Guidelines recommend restrictive red blood cell transfusion strategies. We conducted an observational study to examine whether the rate of peri-operative red blood cell transfusion in the USA had declined during the period from 01 January 2011 to 31 December 2016. We included 4,273,168 patients from all surgical subspecialties. ⋯ Compared with 2011, the adjusted hazard ratios (95%CI) in 2012 and 2016 were 0.96 (0.90-1.02) and 1.05 (0.99-1.11) for myocardial infarction, 0.91 (0.83-0.99) and 0.99 (0.92-1.07) for stroke and 0.98 (0.94-1.02) and 0.99 (0.96-1.03) for all-cause mortality. Use of peri-operative red blood cell transfusion declined from 2011 to 2016. This was not associated with an increase in adverse clinical outcomes.
