Although things may have improved, these problems have not gone away. The UK National Confidential Enquiry into Patient Outcome and Death (NCEPOD) published a report in 2018: ‘Themes and recommendations common to all hospital specialties’.7 The report stated that:
Deficiencies in the recognition of ill patients have been identified for many years and the care of the acutely ill hospitalised patient presents ongoing problems for healthcare services. Deficiencies are often related to poor management of simple aspects of acute care – those involving the patient’s airway, breathing and circulation, oxygen therapy, fluid balance and monitoring. Other contributory factors highlighted in many NCEPOD reports include organisational failures, such as a lack of knowledge, failure to appreciate the clinical urgency of a situation, a lack of supervision, failure to seek advice, delayed response and poor communication.
A number of studies have showed that simple physiological observations can identify high‐risk hospital in‐patients8,9 and implementing a system whereby junior staff are obliged to call for help when there are seriously abnormal vital signs improves outcomes for patients and utilisation of intensive care resources.10,11
Resuscitation is therefore not only about CPR. It is about recognising and effectively treating patients in reversible physiological decline. This is an area of medicine that is often neglected outside critical care areas in terms of training, organisation, and resources.
Medical Emergency Teams
Medical emergency teams (METs) were developed in Australia and consist of doctors and nurses trained in advanced resuscitation skills. The idea is that seriously abnormal vital signs trigger an emergency call rather than waiting for cardio‐pulmonary arrest to trigger an emergency response. Box 1.1 shows the original MET calling criteria. In the UK, early warning scores have been developed to trigger urgent responses (see Table 1.1), usually to the patient’s own team or the ICU outreach team. The purpose of a medical emergency team instead of a cardiac arrest team is simple – early action saves lives. As one of the pioneers of resuscitation commented, ‘The most sophisticated Intensive Care often becomes unnecessarily expensive terminal care when the pre‐ICU system fails’.13
Box 1.1 MET Calling Criteria
Airway
If threatened
Breathing
All respiratory arrests
Respiratory rate <5/ min or >36/ min
Circulation
All cardiac arrests
Pulse rate <40/min or >140/min
Systolic blood pressure <90 mmHg
Neurology
Sudden fall in level of consciousness
Repeated or extended seizures
Other
Any patient you are seriously worried about that does not fit the above criteria
