目的：重症监护中常规使用的许多计算需要了解患者的体重和身高，尽管这些测量并不总是进行。医生或护士的估计经常被替代。本研究旨在确定重症监护室（ICU）工作人员对患者体重和身高估计的准确性。设计：前瞻性临床研究。一所大学教学医院的16张床位的内科和外科混合ICU。由20名医护人员对14名患者的身高和体重进行了评估。测量：在所有评估都被记录下来后，获得了体重和身高的测量结果。通过带有校准称重设施的患者升降机测量体重，并使用钢卷尺测量高度。主要结果，体重的估计值很差，47%的估计值与测量值至少有10%的差异，19%的估计值与测量值至少有20%的差异。大多数身高估计值在测量值的10%以内。个人对体重和身高的估计往往是不准确的。这些估计误差可能会影响有效治疗的应用，并导致临床试验设计敏感性的降低。
Objective: Numerous calculations routinely used in the intensive care require the knowledge of patients' weight and height, although these measurements are not always made. Estimates by doctors or nurses are often substituted. This study sought to ascertain the accuracy of estimates of weight and height of patients made by intensive care unit (ICU) staff.Design: Prospective clinical study.Setting. Sixteen-bed mixed medical and surgical ICU in a university teaching hospital.Patients. Fourteen patients had their height and weight estimated by 20 members of the medical and nursing staff.Measurements: After all estimates had been recorded, measurements of weight and height were obtained. Weight was measured by means of a patient hoist with a calibrated weighing facility and height using a steel tape measure. Main Results., Estimation of weight was poor, with 47% of estimates at least 10% different and 19% of estimates at least 20% different from the measured values. The majority of height estimates were within 10% of the measured values.Conclusions. Individual estimates of weight and height are frequently inaccurate. These errors of estimation could compromise application of effective therapies, as well as contribute to a reduction in design sensitivity of clinical trials.
