PROFILE AND PREDICTORS OF OUTCOME FOR CODE BLUE CASES IN A TERTIARY CARE HOSPITAL IN MANGALORE

Back ground-Code blue is a common emergency code used in case of cardiac arrest in hospital to alert trained emergency response teams. the use of codes is mainly to convey essential information quickly to staff while preventing misunderstanding and panic among visitors in hospital. The aim of the study is to determine the profile and outcome of the patients with activated code blue calls.Methods-This Retrospective record-based study included all patients who had a code blue declared in the year 2022. Data was collected from the patient files from Medical records department and analyzed with descriptive and inferential statistical methods.ResultsTotal 86 code blue calls were analyzed in this study. In Age distribution, age group 60-80 years had the maximum percentage of code blue cases at 58.1%. Code blue cases were more announced for males in the study at 55.8%. For the announced code blue cases it was identified that CPR was initiated by the staff before the arrival of the code blue team with a higher survival chance in these circumstances (60.0%). Asystole was the most common rhythm which was detected in the study at 66.3%. In total patients surviving a code blue call were slightly higher (52.9%) compared to death in code blue cases (47.1%). It was found that early code blue response resulted in favourable outcome where the survival was higher (53.3%) where response time was less than 2 mins.In conclusion, in a hospital set up CPR performed by a trained code blue team can help in better outcome. Initiation of bystander CPR has proved to have a favourable outcome.Better training for the staff can result in better outcome<br>

背景：蓝色代码（Code Blue）是医院内针对心脏骤停事件启用的通用应急代码，用于预警经专业培训的应急响应团队。启用该代码的核心目的在于快速向院内医护人员传递核心诊疗信息，同时避免医院访客产生误解与恐慌。本研究旨在明确触发蓝色代码呼叫的患者的临床特征与转归情况。
方法：本研究为基于病历的回顾性研究，纳入2022年所有被触发蓝色代码呼叫的患者。研究数据从医院病案科的患者档案中提取，并采用描述性统计与推断性统计方法进行分析。
结果：本研究共分析86例蓝色代码呼叫案例。年龄分布方面，60~80岁年龄段的蓝色代码案例占比最高，达58.1%。男性患者触发蓝色代码的比例更高，为55.8%。研究发现，在应急响应团队抵达前由医护人员先行启动心肺复苏（CPR）的案例，其存活概率更高，达60.0%。心室停搏（Asystole）是本研究中最常见的心律类型，占比66.3%。整体而言，蓝色代码呼叫后存活的患者占比略高于死亡患者，分别为52.9%与47.1%。此外，响应时间少于2分钟的早期蓝色代码干预可获得更佳转归，其存活率达53.3%。
结论：在医院诊疗场景中，经专业培训的应急团队实施心肺复苏可改善患者临床转归。旁观者先行启动心肺复苏已被证实可带来良好结局。加强医护人员专业培训有助于进一步优化患者转归。
