    • A method and system for evaluating a subject's weight calculates a moving average of the weight of the subject based on several consecutive weight measurements e.g. on consecutive days. Rather than looking for absolute weight gains of e.g. 2 kg in 48 hours, as with currently accepted guidelines, each new measurement is compared with the calculated moving average, and a first form of alert is generated if the new measurement differs from the calculated moving average by more than a with expected range threshold amount such as by one standard deviation. If the first form of alert is generated consecutively on a predetermined number of successive iterations, a second form of alert is generated different from the first form of alert. The system and method does not assume a stable underlying patient weight, and absolute weight gains over e.g. a 48 hour period are not used as in currently accepted guidelines, which results in earlier alerting of clinical deteriorations and greatly increased sensitivity relative to published guideline methods.
    • 用于评估受试者体重的方法和系统基于几个连续的体重测量来计算受试者的体重的移动平均值。 连续几天 而不是寻找例如绝对体重增加。 在48小时内按照当前接受的指导方针2公斤,将每个新的测量值与计算的移动平均值进行比较,如果新测量值与计算的移动平均值不同,则生成第一种形式的警报,超过预期范围阈值量 例如一个标准偏差。 如果在预定数量的连续迭代上连续生成第一形式的警报,则产生与第一警报形式不同的第二形式的警报。 系统和方法不承担稳定的潜在患者体重,并且绝对体重增加超过例如体重。 目前接受的指南中没有使用48小时的时间段,这导致临床恶化的早期报警和相对于公布的指南方法的敏感性大大增加。
