Following the 1991 Nuffield Theatre Nurses Award, I was encouraged to pursue further research into the scrub procedure. My interest had originally started when looking at the possibility of installing electronic eye taps into the theatres. I reasoned that by reducing the amounts of heated water flowing unused during the scrub procedure I would be able to justify the cost of these taps. A pilot survey I undertook showed that on costs alone this was not proven. A more logical and research based approach to the subject was required. My main objectives were to ascertain costs and timings of the traditional scrub; compare the costs with other acceptable alternatives; explore 'costs' relating to wider environmental concerns; examine the effectiveness of current practice. I looked at the Government statistics for England during 1990/91. It showed an annual total of 741,393 operating sessions with a total of 3,353,797 operations performed. The total of cases in orthopaedic, opthalmic, general and gynaecological operations totalled 2,301,272 cases. These four categories were the ones I chose to research.
1991年获得纳菲尔德剧院护士奖后，我受到鼓舞，对刷手程序展开进一步研究。我最初的兴趣始于考虑在手术室安装电子感应水龙头的可能性。我推断，通过减少刷手过程中未使用的热水流量，我将能够证明这些水龙头的成本是合理的。我进行的一项初步调查表明，仅从成本角度来看，这一点并未得到证实。需要一种更合乎逻辑且基于研究的方法来处理这个问题。我的主要目标是确定传统刷手的成本和时间；将这些成本与其他可接受的替代方法进行比较；探讨与更广泛环境问题相关的“成本”；研究当前做法的有效性。我查看了1990/91年英格兰的政府统计数据。数据显示，年度手术总场次为741,393次，共进行了3,353,797台手术。骨科、眼科、普通外科和妇科手术的病例总数为2,301,272例。这四个类别就是我选择研究的对象。
