There is a very clear need for the expanded application of information technology (IT) in healthcare. Clinical workflow still depends largely on manual, paper-based medical record systems in an activity that is economically inefficient and produces significant variances in medical outcomes. IT spend currently represents around 1.3% of total healthcare spend on average. As shown in Table ES.1, this equates to a global market for healthcare information products and services of $47.5 billion in 2002. The value is forecast to grow by an average of 9.4% per annum to reach $74.5 billion in 2007. As may be expected, the US dominates the market, taking just under 50% of the 2002 global revenues, but will marginally fall back to take under 49% of the total by 2007. During this period, the US market is forecast to grow by an average of 8.9% per annum from $23.7 billion in 2002, to $48.7 billion in 2007. In contrast, the European market will grow at an average of 10.1% per annum, Japan by 8.5% per annum, but the rest of the world, which is currently under-provided with IT, by 10.5% per annum.

医疗保健领域对信息技术(IT)的广泛应用有着非常明确的需求。临床工作流程在很大程度上仍依赖于手工纸质病历系统,这种活动在经济上效率低下,并且在医疗结果上产生显著差异。目前,IT支出平均约占医疗保健总支出的1.3%。如表ES.1所示,这相当于2002年全球医疗保健信息产品和服务市场价值475亿美元。预计该价值将以平均每年9.4%的速度增长,到2007年达到745亿美元。不出所料,美国主导着市场,2002年占全球收入的近50%,但到2007年将略微回落至占总额的不到49%。在此期间,预计美国市场将从2002年的237亿美元以平均每年8.9%的速度增长,到2007年达到487亿美元。相比之下,欧洲市场将以平均每年10.1%的速度增长,日本以每年8.5%的速度增长,而目前IT供应不足的世界其他地区将以每年10.5%的速度增长。表ES.1. 2002年和2007年按地区划分的全球医疗保健IT市场。年份2002年2007年地区收入(十亿美元)占总计(%)收入(十亿美元)占总计(%)年均增长率(%)
