Weight and height documentation: Does ICU measure up?

Abstract

BackgroundReliable assessment and documentation of weight and height are essential for the accurate delivery of many critical care interventions. MethodsWe conducted a 3-month retrospective, cross-sectional, single-centre audit to determine the prevalence of weight and height documentation in the clinical records of patients admitted to the intensive care unit (ICU) for the period from 3 months prior to hospital admission up to hospital discharge. ResultsOne hundred forty-one index ICU admissions were identified from October–December 2015 with 138 medical records available for analysis. Median (interquartile range) age was 64.5 (50.8–75.3) years, the majority were male (60.9%, 84/138), and the ICU admission Acute Physiology and Chronic Health Evaluation II score was 19.0 (14.0–25.0). Overall, weight and height were recorded in 90 (65.2%) and 63 (45.6%) patients, respectively. For elective postoperative admissions (n = 20), weight and height were recorded in 20 (100%) and 19 (95%) patients. For emergency medical and surgical admissions, 70 (59.3%) and 44 (37.2%) patients had weight and height recorded in both the 3-month period prior to hospital admission and the in-hospital period. A moderate, positive correlation was shown, r = 0.55, P < 0.001, with a longer hospital length of stay being associated with a greater number of weight and height records for each patient. In the emergency patient cohort, 81.7% (n = 215/263) of weight- and/or height-based interventions occurred before or during the ICU admission, of which 69.9% (n = 184/263) required consideration of ideal body weight. ConclusionMeasurement and medical record documentation of weight and height is infrequently performed in ICU patients. Given the clinical requirement for accurate measurement and documentation, further research to understand the barriers to perform and document this important process of care is necessary.
