数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据采集:主要观察指标包括基线资料,如年龄、性别、疾病诊断、基础疾病、肝功能、肾功能、查尔森合并症指数评分、危重评分、急性胃肠损伤评分、胃残留量、是否使用镇静药物、是否使用血管活性药物、机械通气比例;螺旋型鼻肠管置管时间、尝试次数、成功率、置管成功时间、管端位置;药物不良反应及置管相关不良事件;置管过程中相关用药及主要治疗措施;新发的ICU获得性感染发生率、新发的ICU 获得性多重耐药菌感染发生率等。记录入选患者基线资料,临床资料,完成相应检查(包括 X 线腹部摄片)并登记、填写病例报告表。 数据记录:原始病历及CRF应按要求如实、认真记录,内容一旦填写不得轻易更改。若确因填写错误,需做更正时,不得改变原始记录,只能采用附加叙述的方式,由负责的研究医生签名并注明日期。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection: The main observation indicators include baseline data, such as age, gender, disease diagnosis, underlying diseases, liver function, renal function, Charlson Comorbidity Index score, critical illness score, Acute Gastrointestinal Injury score, gastric residual volume, whether sedative drugs are used, whether vasoactive are used drugs, and the proportion of mechanical ventilation; the intubation time, number of attempts, success rate, successful intubation time, and tube tip position of the spiral nasointestinal tube; adverse drug reactions and tube placement-related adverse events; relevant medications and main treatment measures during the tube placement process; the incidence of new ICU-acquired infections, the incidence of new ICU-acquired multi-drug resistant bacterial infections, etc. Record the baseline data and clinical data of the enrolled patients, complete the corresponding examinations (including abdominal X-ray), and register and fill out the case report form. Data recording: The original medical records and CRF should be truthfully and carefully recorded as required. Once the content is filled in, it should not be easily changed. If a correction is indeed necessary due to a filling error, the original record should not be altered. Instead, only an additional narrative method can be used, and the responsible research doctor should sign and indicate the date.
