Frequency and potential causes of non-beneficial Code Blue activations at a metropolitan teaching hospital.

Abstract

Code Blue activations in patients who are not for resuscitation (NFR) may be regarded as non-beneficial and may cause harm to patients, relatives and hospital staff. To estimate the prevalence of non-beneficial Code Blue calls in a metropolitan teaching hospital and identify modifiable factors that could be utilised to reduce these events. The study consisted of two parts: (i) a retrospective analysis of all Code Blue activations over a 12-month period using prospectively collected data. Non-beneficial activations were defined as calls made in patients with a NFR order in either the current or any previous hospital admissions and (ii) an anonymous voluntary survey of staff who were present at a Code Blue activation. There were 186 Code Blue activations over the study period, with 48 (25.8%) defined as non-beneficial. Such patients had more comorbidities, previous hospitalisations and greater levels of frailty. Most non-beneficial calls occurred on general wards and more than three-quarters of patients had been reviewed by a consultant prior to the call. The survey determined that despite ward staff having a considerable degree of resuscitation experience, there were deficiencies in understanding of Code Blue criteria, the resuscitation status of patients under their care and the interpretation of goals of care. Over a quarter of Code Blue calls were deemed non-beneficial. Improving the visibility of NFR status and staff understanding of patient goals of care are needed, along with timely, proactive documentation of NFR status by experienced clinicians.
