最近，IDC对2015年的HIT做出预测，认为大数据会继续在2015年引领风骚，与此同时，信息安全问题也会凸显。IDC在其题为《未来图景》的报告中做出如下几点预测：

1、    到2015年，有一半的医疗机构在过去的12个月内会遭受1到5次网络攻击，其中三分之一攻击成功。

2、    到2018年，65%的与医疗机构之间的“消费交易”将会是通过移动设备进行，这就需要医疗机构制定好互联网、移动医疗和电话服务战略。

3、   为了帮助管理好慢病，到2018年，有70%的医疗机构会投资于移动App、可穿戴设备、远程健康监测和虚拟医疗。这些投资将增加对大数据和数据分析的需求，以支持人群健康管理计划。

4、   到2018年，半数的健康和生命科学的付费者（如医保公司）会要求与其外包合作伙伴（如医疗机构）有实质性的风险分担，以强化他们在整体变革中日益提升的重要作用。

5、   随着越来越多的医生和医疗机构对数据的收集、汇总、分析和决策转向云计算，到2020年， 有80%的医疗数据会在其生命周期的某一时点，穿“云”而过。

2015 healthcare predictions: Growth in analytics, mobile, security risks

Big data  continues to dominate the 2015 predictions for health IT from IDC Health  Insights, though security plays a major role as well.

Among the  predictions in the IDC Future Scape for Health Insights report:

By 2015, half of healthcare organizations will have experienced one to five cyber attacksin the previous 12 months, with a third of those attacks successful.

By 2018, 65 percent of consumer transactions with healthcare organizations will be through mobile devices, requiring organizations to develop strategies for Web,mobile and telephone.

To help manage chronic conditions, 70 percent of healthcare organizations will invest in mobile applications, wearables, remote health monitoring, and virtual care by 2018. Those investments will increase demand for big data and analytics capability to support population health management initiatives.

By 2018, half of health and life science buyers will demand substantial risk sharing with outsourcing partners to emphasize their growing role in overall improvements.

By 2020, 80 percent of healthcare data will pass through the cloud at some point in its lifetime as providers increasingly turn to the cloud for data collection, aggregation, analytics, and decision-making.

The predictions  are designed to present a roadmap to organizations for the planning and  budgeting process for their health IT expenditures, Scott Lundstrom, group  vice president and general manager of IDC Health Insights, says in an announcement.

Telemedicine and digital health  will be ubiquitous as healthcare reform continues to take  hold, according to University of Pennsylvania-based health economist Ezekiel  Emanuel.

"The  hospital won't be the locust of care that it has always been," he said  in his keynote speech Tuesday at the New York eHealth Collaborative's Digital  Health Conference.

Applications for population  health management that integrate claims and clinical data  will vital to the success of accountable care organizations (ACOs), IDC  Health Insights said in a previous report.
