BACKGROUND: True alarm rate of the Code Blue cases is at a low level in the Dr. Beh?et Uz Children’s Hospital in ?zmir. This study aims to analyse the use of the Code Blue alarm cases in the children’s hospital.METHODS: This retrospective clinical study evaluated the age and the gender of the cases, the arriving time of the Code Blue team, the date and time of the Code Blue Call, the reasons of the Code Blue Call, and the verifi cation which were all obtained from the Code Blue forms of the hospital dated between January 2014 and January 2015. The data of 139 Code Blue cases’ forms were investigated and was divided into two groups: before and after the education containing 88 and 51 cases, respectively.RESULTS: Conversive disorder(26% to 13%, P<0.01), syncope(21.5% to 19.6%, P<0.01), convulsion(17% to 13.7%, P<0.01), hypoglycemia(4.5% to 3.9%, P<0.01), anxiety(4.5% to 1.9%, P<0.01), head trauma due to syncope(4.5% to 0%), cardiac arrest(1.1% to 0%), respiratory difficulties(2.2% to 1.9%, P<0.01), suspicion of myocardial infarction(2.2% to 1.9%, P<0.01), fall from stairs(2.2% to 0%) and agitation cases(1.1% to 0%) were reduced, however, the hypertension cases were dramatically increased(3.4% to 29.4%, P<0.01) owing to the hospital staff’s education. The Pearson’s correlation coeffi cient before and after education was 0.837. About 97.8% of the Code Blue cases were false calls with female greater than male(P<0.01).CONCLUSION: The results of this study show that more education is required for the hospital’s staff and a new color code that is to say pre-diagnosis team should be formed.
