While coat contamination increases progressively with the duration of use, there are no guidelines on how frequently medical white coats should be changed. The purpose of our study was to examine the turnover of individual batch of medical white coats in a university hospital.
A retrospective analysis of the white coat turnover of 826 physicians was performed by using the hospital laundry computerized database and an electronic declarative survey (240 responses) to evaluate the duration of medical white coat use.
There was a wide discrepancy between the data extracted from the laundry database and those from the survey. The median factual duration of use (20 days, range: 15-30) corresponding to a turnover of 2 (1-2) coats per month, was widely underestimated by the physicians. Multivariate analysis identified 4 independent factors associated with a declared use of coats longer than 7 days: estimation of insufficient gown turnover (OR 14.8 [4.8-45.8]), daily change considered as not useful (OR 5.1 [2.4-10.8]), non-medical specialty (OR 2.95 [1.5-5.6]) and presence of stains on gowns (2.9 [1.5-5.5]).
Shortening white coat use should be included in medical education in order to improve the good practice rules of hospital hygiene.
虽然白大褂的污染程度会随着使用时间的延长而逐渐增加，但对于医用白大褂应多久更换一次，目前尚无相关指南。我们研究的目的是调查某大学医院中一批医用白大褂的更换频率。
通过医院洗衣房的计算机数据库和一项电子问卷调查（共收到240份回复），对826名医生的白大褂更换情况进行回顾性分析，以评估医用白大褂的使用时长。
从洗衣数据库提取的数据与调查数据之间存在很大差异。实际使用时长的中位数为20天（范围：15 - 30天），相当于每月更换2（1 - 2）件白大褂，但医生们普遍低估了这一数据。多因素分析确定了与宣称使用白大褂超过7天相关的4个独立因素：认为工作服更换不足（比值比14.8 [4.8 - 45.8]）、认为每日更换无用（比值比5.1 [2.4 - 10.8]）、非医学专业（比值比2.95 [1.5 - 5.6]）以及工作服上有污渍（2.9 [1.5 - 5.5]）。
应将缩短白大褂使用时间纳入医学教育，以改善医院卫生的良好实践规范。
