Prevention of cardiopulmonary arrest in hospitalised patients is the first and most important step in the life-saving chain. When the condition of the inpatients is worsened, nurses are usually the first to see and evaluate the patient. The aim of this study was to evaluate the attitudes of the nurses working at the Mersin University Hospital, during their routine follow-up to the deteriorating patients and the early warning scoring (EWS) awareness.A web-based questionnaire was sent to all nurses working in inpatient services and intensive care units (ICUs) and registered to the hospital database at Mersin University Hospital via e-mail. In the questionnaire, a total of 10 multiple-choice questions were asked to the nurses questioning the unit they worked for, the EWS they used, the complaints they frequently complain about and the applications for the call for help. A total of 146 nurses were included in the study.43.8% (n ¼ 64) of the participants were in ICU, and 56.1% (n ¼ 82) were in service units. Participants were asked whether they used a special scoring system to recognise the deteriorating patient; 45.2% (n ¼ 66) used the scoring system; and 54.8% (n ¼ 80) reported that they did not use it. Participants working in ICU were more likely to use EWS system. Participants answered the most commonly used scoring system as the Glasgow Coma Scale (n ¼ 40). The participants reported that the most common respiratory distress (n ¼ 135), changes in consciousness (n ¼ 109), palpitations (n ¼ 98) and chest pain (n ¼ 92) occurred in the deteriorating patients. Participants reported that they frequently asked for help from a doctor (80.1%), other nurses (7.5%) and a blue code team (7.5%).According to the findings, it is necessary to determine the habits of calling for help and raising awareness for a functional EWS.

Objective Globally, previously determined teams activated by 'code blue' calls target rapid and organised responses to medical emergency situations. This study aimed to evaluate the cardiopulmonary resuscitation (CPR) conditions in Turkey. Methods A web-based survey was sent to anaesthesiologists in Turkey via email. The survey included 36 questions about demographic features and 'code blue' practices and procedures. Results A total of 180 participants were included. The mean working duration was 16.1±7.5 years. Of the anaesthesiologists who participated, 35% worked in university, 26.1% in education and research, 1.7% in city hospitals, 18.9% in state hospitals and 18.3% in private hospitals; 68.3% had CPR certification. There were code blue systems in 97.6% of the organisations. For code blue calls, 71.9% were activated by calling '2222'. There were 41.5% organisations with code blue teams of 3-4 people, whereas 26.7% had 2-member teams. Among call responders, 68.5% were anaesthesia technicians/paramedics, 60.7% were anaesthesiologists and 42.7% were anaesthesia assistants. In organisations, 66.3% regularly conducted code blue training. In total, 63.3% of the participants stated that the time to reach the location was nearly 2-4 minutes. During CPR, the use of capnography was 18.3%. Of the participants, 73.8% chose endotracheal intubation as priority airway device during CPR. Conclusion Today, code blue practice is an important quality criterion for hospitals. This study shows the current status of 'code blue' according to the results of respondent data completing the survey. To prevent in-hospital cardiac arrest, a chain of preventive measures should be established, including personnel training, monitoring of patients, recognition of patient deterioration, the presence of a call for help system and effective intervention.
