A systematic analysis of Hospital Episodes Statistics (HES) data was done to determine the effects of the 2017 WannaCry attack on the National Health Service (NHS) by identifying the missed appointments, deaths, and fiscal costs attributable to the ransomware attack. The main outcomes measured were: outpatient appointments cancelled, elective and emergency admissions to hospitals, accident and emergency (A&E) attendances, and deaths in A&E. Compared with the baseline, there was no significant difference in the total activity across all trusts during the week of the WannaCry attack. Trusts had 1% more emergency admissions and 1% fewer A&E attendances per day during the WannaCry week compared with baseline. Hospitals directly infected with the ransomware, however, had significantly fewer emergency and elective admissions: a decrease of about 6% in total admissions per infected hospital per day was observed, with 4% fewer emergency admissions and 9% fewer elective admissions. No difference in mortality was noted. The total economic value of the lower activity at the infected trusts during this time was £5.9 m including £4 m in lost inpatient admissions, £0.6 m from lost A&E activity, and £1.3 m from cancelled outpatient appointments. Among hospitals infected with WannaCry ransomware, there was a significant decrease in the number of attendances and admissions, which corresponded to £5.9 m in lost hospital activity. There was no increase in mortality reported, though this is a crude measure of patient harm. Further work is needed to appreciate the impact of a cyberattack or IT failure on care delivery and patient safety.

通过确定错过的约会，死亡和勒索软件攻击造成的财务成本，对医院情节统计（HES）数据进行了系统分析，以确定2017年WannaCry攻击对国家卫生局（NHS）的影响。衡量的主要结果是：门诊预约取消，医院的选择性和紧急入院，事故和紧急事件的出勤率以及A＆E中的死亡人数。与基准相比，在WannaCry攻击的一周中，所有信托的总活动没有显着差异。与基线相比，信托基金在WannaCry期间的每日急诊住院人数增加了1％，每天的急诊就诊人数减少了1％。但是，直接感染了勒索软件的医院的急诊和选择性入院率大大降低：每天每家被感染医院的总入院率下降了6％，紧急入院率下降了4％，选择性入场率下降了9％。死亡率无差异。在这段时间里，受感染信托的较低活动的总经济价值为5英镑。900万英镑包括9百万英镑的住院病人误入医院，60亿英镑因急诊和医疗活动损失以及130万英镑因取消门诊任命而造成的损失。在感染了WannaCry勒索软件的医院中，出勤率和出诊率显着下降，相当于损失了590万英镑的医院活动。尽管这是对患者伤害的粗略衡量，但并未报告死亡率增加。需要进一步的工作，以了解网络攻击或IT故障对医疗服务和患者安全的影响。尽管这是对患者伤害的粗略衡量，但并未报告死亡率增加。需要进一步的工作来了解网络攻击或IT故障对医疗服务和患者安全的影响。尽管这是对患者伤害的粗略衡量，但并未报告死亡率增加。需要进一步的工作，以了解网络攻击或IT故障对医疗服务和患者安全的影响。
