We studied the relation of body weight to lengths of stay and total charges for all patients hospitalized at the Brigham and Women's Hospital for total knee replacement and total hip replacement during a 12-month period. Patients with moderate obesity (actual body weight 141-170 per cent of ideal) had lengths of stay and total charges similar to normal weight patients (body weight 100-110 per cent ideal). However, patients who were extremely overweight (body weight greater than or equal to 188 per cent ideal) had mean lengths of stay 35 per cent longer (28.9 days vs 21.5) and total charges 30 per cent higher ($25,692 vs $19,576) than patients with normal weight. Those who were extremely underweight (body weight less than or equal to 75 per cent ideal) had mean lengths of stay 40 per cent longer (30.1 days vs 21.5) and total charges 35 per cent higher ($26,447 vs $19,576).
我们研究了在12个月期间于布莱根妇女医院接受全膝关节置换术和全髋关节置换术的所有患者的体重与住院时间及总费用之间的关系。中度肥胖患者(实际体重为理想体重的141%-170%)的住院时间和总费用与正常体重患者(体重为理想体重的100%-110%)相似。然而,极度超重患者(体重大于或等于理想体重的188%)的平均住院时间比正常体重患者长35%(28.9天对21.5天),总费用高30%(25,692美元对19,576美元)。那些极度体重过轻的患者(体重小于或等于理想体重的75%)平均住院时间长40%(30.1天对21.5天),总费用高35%(26,447美元对19,576美元)。
